DROP IN Brushless Upgrade Guide for WL TOys 144001, 124018 and 124019 [QuadifyRC]

21/1/2021

136 Comments

 
WL toys have had a series of hits with the 1/14 scale 144001 and now more recently with the 1/12 scale 124019 and 124018 - same car just a little longer. In order to hit their price point though they have had to compromise on the power train - opting for brushed motor technology that although surprisingly fast offers poor long term durability and even worse efficiency leading short running times. Upgrading to brushless is a solid option but has required hacks and workarounds in the past to get anything other than basic speed run builds. This new guide aims to be drop in solution with no mechanical modification required.
Picture
Just to recap I've already made 3 brushless builds. If you have the ability I still highly rate the ultimate brushless upgrade as I believe the motor and gear combination is perfect for fast, reliable and efficient 2s running.
  • 144001 ultimate brushless upgrade guide (2838 4500kv and 17t pinion) - also for 124019 and 124018
  • 144001 no cut option (as above with 15t requires rebore of the pinion) - also for 124019 and 124018
  • 144001 speed run build (3650 5200kv on road only) - also for 124019 and 124018​

Build objective
The core objective for this build is to make the process as simple as possible - servos, receivers, motors, gears all bolt up directly without having to re-drill, slot or fabricate anything. For full disclosure the ONLY cutting that is required is removing a little of the thin plastic on the motor shroud - purely cosmetic and can be done easily with a craft knife or nail scissors. The end result of a car that is very quick (48mph/78kph on 2s and 68mph/109kph on 3s) and has superior handling due to reduced weight that is suitable for on road and offroad with markedly improved battery life
Picture
Competed build - I've installed in the 124018 but it would work as well as or even better in the 124019 or 144001

Parts I used plus alternatives
All parts are listed below. I've listed alternative items with same or similar specs should there be stock issues. 
Radio
Radio will need to be replaced, you cannot use the stock item for a brushless upgrade. DumboRC make an excellent budget model or you can upgrade to the FlyskyFS-GT5
Picture
The Dumbo X6 (with gyro) is typically the best value option: review is here
Picture
The X6a is identical to the X6 but cosmetically a little different: review is here.
Picture
The flysky FS-GT5 is a little more expensive but offers a lot more features, especially if you want to use it to control multiple cars. Review is here.
Servo
The stock servo will need to be replaced with a 3 wire servo. I recommend the reliable PDI-1181MG but it is often out of stock. The Emax ES3054 is a good replacement as is the newly released surpass hobby 17g metal servo
Picture
JX Digital Servo 17g Metal Gear PDI-1181MG This is a direct replacement for the stock servo that is faster with metal gears but often out of stock
Picture
Surpass-Hobby 17g Metal  Gear Servo. A new one from Surpass is working well in a new build I have. Good alternative to the 1181MG if unavailable
Picture
​Emax ES3054 17g 3.5kg 0.13sec Metal Gear Digital Servo. Another good alternative to the 1181MG if unavailable
Motor
On to the fun stuff! The motor is the most unique part for this build. For size I've chosen the 2445 as the longest barrel 24xx motor available. It has the correct mounting points for the stock bracket and importantly has m2.5 mounting screws (no drilling of the motor mount) and a 2.3mm motor shaft meaning no re-boring of the 15t pinion gear. Ideally I  would have liked 4500kv but have gone with 5400kv and will use exclusively on 2s. Consider 3500kV as a milder option that is capable of running 3s quite happily
Picture
Racerstar 2445 Motor Senseless Brushless Waterproof 5400/3600/3000KV. As Above I recommend 5400kv but 3600kv is a good option if you want it to run a little slower and cooler.
Picture
Surpass Hobby 2445 KK Series 2S Brushless Waterproof Motor 3000/3600/5400KV. Make no mistake, this is the same motor but under it's original name - Racerstar is a house brand for Banggood.
Brushless ESC
I don't think anyone will question my use of a premium hobbywing ESC (such is their quality and performance) but I know I will ruffle a few feathers by recommending the 30A 16BL30 model. My reasoning is simple. This is the unit that is OEM'd for the LC racing EMB series which run 2838, 2938 and 2850 motors ranging from 4500-5000kv on 2s AND 3s. These are well made cars and have shipped with these ESCs for years with little to no complaint on the ESCS even on 3s. I've also listed a budget surpass equivalent but strongly recommend the 16BL30. If you remain unconvinced, consider the 120A Hobbywing 10BL120 as an overkill ESC that has a massive amount of overhead yet remains highly compact for a simple build.
Picture
Hobbywing QuicRun WP-16BL30 Brushless Waterproof 30A Sensorless ESC. This is a high-quality programmable compact ESC that is well suited to motors in this size range. Rated for 2s and 3s.
Picture
Hobbywing QUICRUN 10BL120 Sensored 120A 2-3S Lipo Speed Brushless ESC. Much higher rated ESC if you want the additional power overhead. Not waterproof but capable of running sensored motors too.
Other parts
These are the must-have other parts needed for the upgrade. Not sexy but crucial - especially the unicorn pinion that I found after a months of searching and testing.
Picture
0.7m 15t pinion with 2.3mm bore. The only pinion available in this size. The magical piece that allows for this upgrade. Link for another seller here
Picture
Motor mount for 124019 124018 144001. I recommend this as a critical part because it is difficult to remove the stock item in 1 piece
Picture
M2.5 Countersunk Screw (50 pcs). Buy in 8mm length. More than enough to use for the motor mount and replacing damaged items. Require a 1.5mm hex driver.
Picture
Amass T Plug Connector Male Female With Sheath. These will need to be soldered on in place of the mini Tamiya plug. If you want to save a little money and have heatshrink there is this option too.

Install Guide
Now that you have all the parts it's time to put it all together. I've installed in a 124018 here but images are the same for 124019 and 144001 as well.
Picture
First remove these screws to remove the upper deck. You'll note these first 6 images are from the 144001 but the process is the same
Picture
Remove the whole assembly above by unplugging the motor bullet connectors. You can also remove the gear shroud
Picture
This is how it should look now, you can remove the servo at this stage.
Picture
These are the two screws you'll need to remove for the motor mount which use a very strong loctite. I was able to remove without heat on 2 cars but needed to drill out on 1 car. Never fear, the screws I recommended (m2.5x8) work here as well
Picture
Screws are out
Picture
Now if you rotate the motor and mount about the bearing on the bracket you can remove. I strongly recommend against reusing this bracket because even if you do get the motor screws out, the pinion will strip 99% of the time. Just leave this unit as is
Picture
Here I've used m2.5 x 6.5mm screws to mount the motor but the m2.5 x 8mm i've recommended are a better length. New motor mount of course - always have one of these spare for a build like this.
Picture
You can see the at M2.5 countersunk screws fit in the close mounting position PERFECTLY - unlike when you use M3 countersunk redrilled as per my other guides
Picture
Hex driver here is pointing to where a small amount of material needs to be removed from the gear shroud to allow the motor to fit in this closer position
Picture
I used a (blunt) craft knife to remove this material but it is so thin an flexible that a pair of nail scissors will probably give you a better finish
Picture
Not a beautiful job but the motor will be covering this all anyway.
Picture
Now loosely slide the pinion on the motor shaft and reinstall the same way you removed from the car. ​New m2.5 x 8mm screws going back in that you bought. You did get them right?
Picture
With the motor mount fixed in place, tighten the pinion with a good 1.5mm hex driver so that it sit square with the spur gear
Picture
End result looks like this. The one positive with a fixed motor mount is that when you use the right motor in the right location with the right gear then the mesh is just PERFECT
Picture
Next I marked out where the material needed to be removed on the upper gear shroud...
Picture
... And removed
Picture
Keep test fitting to make sure you don't remove too much. You can see when enough have been taken away it sits square with no fouling.
Picture
Top plate goes back on. Try not to lose any screws like I did 🤦‍♂️
Picture
Here is the first test location I had for my gear. Before you fix anything down make sure you test with the body on in battery in place etc to make sure everything fits cleanly.
Picture
Since this particular install is on a 124018 I found the canopy fouled on the top of the servo plugs coming out of the receiver as seen above. This wouldn't be a problem in the 144001 or 124019
Picture
Ultimately I landed on the receiver between motor and ESC. It will get warm but receivers don't really mind the heat. This is only possible on the longer wheelbase 124019 and 124018
Picture
I like to secure excess motor wire with a cable tie but with no obvious points to run it through I drilled a 3mm hole in the top deck as above
Picture
And got just the security I needed
Picture
Here it is all reassembled - not a lot of room in the 124018

Performance results
For those that follow me on facebook (here if you want: Quadifyrc on facebook) you'll know that I've been testing this for about 2-3 months at time of writing in order to give you the best possible view rather than slapping it together and hoping for the best.
Weight and weight distribution
Moving to this setup will save you weight (130g to be specific) in all the right places, namely the rear of the car. This will be a minor improvement to the balance of the 124019 and 124018 given the longer chassis length and a major improvement for the 144001. This will make the car more balanced through corners and a lot more even over jumps. It will also make the suspension much easier to dial in,making the rear springs a little more suitable given they are not carrying excess weight.
Power and speed
You probably didn't come here to read about improved weight balance though so on to the speed. With the 2445 5400kV motor I got 78km/hr (48 mph) using the stock 2s battery on stock tyres running on the road. It's not speedrun-fast, but it is more than fast enough to know that you need to take care when cornering. Running it offroad, (even on the P6973 tyres I heartily recommend in this article) it is *barely* controllable and  faster than the 2838 brushless upgrade I talked about in this article. Another benefit over the original 2838 brushless upgrade article is that the ESC is much smoother, cogging at even the lowest speeds is all but gone. Combined with a perfect gear mesh this is just such a smooth car now.
Picture
Update: On 3s I got a whopping 109km/h (68mph) - more than I was expecting! The cooling mod I mentioned below has really helped and was happy with motor and ESC temperature. Perhaps even more amazing was the battery pack voltage after a down of these passes. I was expecting it to be near depleted but look what I got below... Just to be clear, I got this speed using a 30A ESC and 30A Xt30 connectors. I may have found a new niche class - efficient speed runs 🤣
Picture
I used a China Hobbly Line 2s 2200mah 40c pack for this run. Does the job well. 
Picture
3.93 volts per cell after 12 passes? Madness! Could have gone for more but I reckon I'd be tempting fate with a crash
Picture
109km/h is more than I was hoping. Remember this is not set up as a speed run car - I am using the tiny 15t pinion. I think this could go even faster with a 17t pinion if you really wanted but not really my thing.
The issues I've found + solutions
​Just to show you I'm not trying to shove this upgrade down your throat it isn't all rosy though. This combo does seem to run hotter on 2s compared to the 2838 upgrade and that makes sense - a side effect of the faster, higher kV (5400 vs the 4500kV 2838) means that it does produce more heat. In fact during my torture testing with the bigger P6973 tyres on thick grass with the 124018 chassis, I managed to get the thermal cut off on the Hobbywing 16BL30 ESC to kick in - lucky it has one and certainly a reason why I like this ESC. I haven't had this kick in since though just something to bear in mind. In order to balance this argument though the 124018 is the worst car for cooling - all gear is housed tightly under the canopy with very little airflow - I suspect this would be much better on the 144001 and 124018. Also it is the middle of summer here and was around 25°C during my testing. 
Efficiency and battery life
Based on the above it is understandable that power consumption was up on the 2838 4500kv, with the stock 2200mah battery lasting around 15 minutes on the 2445 5400kv. Although an improvement over the stock motor's 10 minutes, the 2838 would probably run about 20 minutes on the same pack. After a full run I found the battery is only just warm, a good sign that the power drain is not so high as to stress that battery.
Venting
​I've written a brief article here (article to come soon - pics below for now) to greatly increase cooling without use of fans or additional heatsinks. This  solution is only suitable for driving in conditions that are not muddy nor dusty. Here is the link to this breakout article which is applicable to the 124018, 124019 and 144001. I've found this change has been really effective, even with ambient temps of 22-25°C
Picture
More air in at the front
Picture
More air out at the back
Picture
Forced airflow at speed over the ESC and motor helps keep it cool
Reducing timing via ESC settings
Another option to use instead or as well as the extra venting is changing some of the ESC settings (namely timing). Since the 16BL30 used here and the 10BL120 is fully programmable directly from the ESC as supplied you can easily turn back timing from the stock value of 11.25°. I haven't done this because I don't feel it necessary but if you do experiment with the lower values to see what works best for you. Remember, more timing = more power and more heat and vice versa
Picture
The stock setting for the 16BL30 ESC is 11.25 degrees, reducing this value will cause the motor to run a little slower and cooler just like reducing timing on a 1:1 car. I didn't find this necessary. Full manual to the right if needed

Update! Reducing the timing can definitely help get the heat under control if needed, see my new article on timing specifically for this setup here:
https://www.quadifyrc.com/rccarreviews/brushless-motor-theory-adjust-esc-timing-to-control-power-and-heat
Reducing motor kV
Sadly the next step down in 2445 sized motors is only 3600kV and think this is a little low for 2s operation but would be good for 3s. I have ordered one to try for completeness and will report back on comparison to my expectations here with recorded speed. You will note that the 2440 motor is available in 4600kv but my genuine opinion is that this stator is just too small - more than 10% less volume than the 2445. UPDATE: I've tried the 3600kv and actually really like it on 2s and 3s. This motor is now my preference for bashing and keeping temps under control. See this article for more detail ​RC CAR THEORY: 2S VS. 3S, HIGH KV VS. LOW KV
Update! I've done extensive testing on the 5400kv AND 3600kv motors now for speed, heat and battery life on 2s and 3s. All the results, a whole lot of theory and my conclusions/ recommendations are here:

A riddle solved
When I set out on my 144001 journey, the motor mount with alternative mounting points always perplexed me. Why would they go to the effort of putting specific mounting holes in the mount if they weren't going to use them? - they obviously had something in mind. Weird thing was though that nothing was ever released to take advantage of them. Now that I've used the 2445 motor with 15t though pinion I do think this was the original objective - it just fits so easily and perfectly that I think this was the upgrade path that was planned all along. 
Recommendations
If you want a simple a straightforward brushless upgrade suitable for on and offroad for the 124019, 124018 or 144001 with no extra drilling or cutting then I strongly suggest that this is the mod for you. Yes, a 3650 brushless motor with stock pinion will also drop straight in but I stand by my opinion that I believe these are only suitable for straight line on road cars; the weight makes them corner and jump poorly plus the heat buildup is significant, even on lower kV motors. Cogging is also an issue with the tall stock gears on 3650 motors.

I have tried to make this guide as complete as possible with all of the parts and options clearly laid out so that you can swap if there are stock or pricing issues or even upgrade spec if you wish. You can of course use other parts but I've specifically mentioned products here that I have direct experience with that have held up to my testing. Banggood do have all of these available except for the 15t pinion gear which I'm working on (Hao, if you are reading this 😉). 

There are of course compromises that have been made to bring you a drop in solution such as a slightly higher kv motor than desired but you will still have a fast and reliable car as a result that is easy to build. If you are more of a tinkerer though I still rate my ultimate brushless build for the 144001, 124019 and 124018 as not the fastest but the most well balanced build.
Exact parts I used in this upgrade:
Racerstar 2445 5400kv Brushless Motor
Hobbywing 16BL30 Brushless 30A 2-3s ESC
Dumbo X6a radio gear with gyro
PDI 1181-MG 17g Metal Gear Servo
0.7mod 15t pinion gear

I found this 2445 in a 4700kV, but it costs more than $75 US shipped to the states. Can't really justify spending that much money on just the motor.

Where did you put the receiver and esc on the 144001? Did the 2445 motor left enough place to mount something next to the steering servo? On my car, with the 2838, the flysky receiver is a very tight fit in there and the 2445 should be longer...

I used the 124018 here so more room lengthwise. On a 144001 there is more room in the cab so I would mount the receiver on the top deck

Hi quadify,

I'm following this guide very closely and have all the parts on order except for the AMASS tplug connector. Your link for this item is not working and im unsure which product to use instead (complete newbie here).

Could you or anyone else please update the link and/or point me in the right direction for a suitable replacement?

Much thanks in advance, this is the last piece I need to complete my build. All help greatly appreciated.

You are a legend, thank you so much, I really appreciate your help. I don't use Facebook, but I will surely let you know how the 2445 build goes.

I was going to leave my car stock to be honest, but i had been bashing about all fine no problems, then went and did a few road runs and the drive train locked up. Upon inspection the motor pinion had slipped out at an angle AND was missing three teeth. Hardly barely run it.

Seems like a good excuse to upgrade. Thank you once again for your guides.

Man this read up was absolutely epic and just made me ready for some serious next steps. An absolute noob to this RC world and I just got the exact same motors to upgrade a brushed 1:16 car to mean machine brushless beast . I have the 2445 and 2440 ( 2445 is 5400 kV and 2440 is 4600)from surpass and a 35 amp ESC for one and stock 2in1 receiver that isn't enough lol I learned. So after converting to the 35 amp ESC and 2445 on 2s was a savageee but the battery drained way fast .. so now it's time to get way bigger battery and swap the 35 amp ESC to the 2440. And get a bigger one for the 2445 I would assume itl run cooler and make battery last longer etc etc .. what size ESC/ speed controller can you run. What's the best one for the 2445 5400kv do you think

I love your guides. This site my my bible for WLToys Mods, in my eyes. A small opinion: I think it would be great if at the end of your articles, if you put a list of links (even affiliate links) with everything you recommend in one place would help us with easy buying. Even if you had like a "best, great, good" lists with all the links, that way when we are done reading everything, we can just click and buy. I've seen this on youtube videos and I can only think folks other than me would appreciate that.

Just a suggestion. We all appreciate everything you do.

Hi Cyrille

No problem! I've ordered the 3600kv but it is out of stock - will update when I have one here. The 5400kv is much better with the cooling added as mentioned in this article. The 124018 has terrible airflow and would expect to be better in the 124019 or 144001 stock

Hi QuadifyRC, would you recommend this same upgrade for running a 124018 on the beach preferably with paddle tires? Or would you suggest a differennt motor with perhaps more torque and/or less speed?

Any other suggestions for running a 124018 on the beach are appreciated

This is a great point. I just bought a 124018 whilst waiting for my brushless upgrade to arrive for my 144001. I live by a few beaches and have been checking out paddle tires, but have yet to find any with a similar diameter to stock wheels. A change in motor is probably the solution. A lower KV thus bigger torque brushless upgrade perhaps?

I'll let you know if I find any decent tires!

Best tyres I've found in this size is the Remo P6973 which would be ok in hard packed sand but not as good as paddles in soft sand

Re: 5400kv vs 3600kv? Assuming Kv is somewhat accurate and drivetrain is efficient then 1/3 slower.

Hi Arie

Paddle tyres have a large diameter so I'd recommend going with the lower KV option to offset this (3600kv). CHeers.

How notable a difference would the 3600kv be in comparison to the 5400kv, in terms of general use. Will the top speed be much lower?

Really nice website with all the info you supply! Great job!

Just a quick question, i'm going to buy the 124019. Just doubting what esc combo to put in. Since i'm not a soldering hero I would like a combo which is allready put together with wires. What you say about this setup? Want to run it on 3s and hoping to get around 70 mph. Would that be a good setup? Or would you recommend a other combo?

Thanks Erwin

I'd recommend this combo here, there a lot of options for ESC and motors out there - good, bad and awful. I spent a lot of time research and testing this and other combos and so stand by it. When you start changing parts in and out it becomes more difficult. That combo you linked is ok but I don't recommend it in this car as it will be heavy, inefficient and has poor control at low speeds.

Hi,
I'm an RC newbie. I'm still waiting for my 124019 to be delivered. I've read your articles and it's a wealth of information! Thank you so much!

Can you tell me if this motor/ESC combo will work for this car?

Great Guide!! By doing a brushless upgrade and reducing the gearing to from 27t to 15t, would it be possible to put some larger tires on it in order to make it more of a basher?

For sure but would recommend the low kv option. Bigger wheels and tyres will also stress your driveline more

Hey Quadify, I just found this while browsing through Ebay for Wltoys 144001 parts (Amazon doesn't stock many): https://www.ebay.com/itm/LC-RACING-Motor-Gear-SetEMB-1-EMB-SC-EMB-WRC-EMB-MT-EMB-DT-EP-1-14-RC-Car-L6032/174357336936?hash=item289881d368:g:AwkAAOSwnu1egh2h

Dang, I thought I found a hidden treasure here! Another question, couldn't we use the pinions I found with the stock LC Racing spur gear? This way they would mesh, or is the central driveshaft diameter different, or the pinion bore different since LCR uses 28xx motors?

So I just finally got my version of this build completed in a 144001 with Remo body mounts and short course truck shell, lc racing springs and various metal upgrades...

IT IS INCREDIBLE.

It's almost scary fast, I can pull wheelies from start or even if I slam the throttle whilst already half on it. I love it.

Is very smooth, but you can get it to cog slightly if you try. It does get fairly hot and I'm wondering about an added heat sink, but I haven't managed to hit the cutoff temp, so assume all is good.

I set the lipos to cut off at 3.4 on the ESC but they seem to stop at 3.7 for some reason. Are there any particular settings you recommend when programming the ESC quadify? So much to play with.

Overall, I'm absolutely blown away, this feels like a really serious RC car now. I've ordered 4 of the clear Remo short course shells to get creative with, that's me entertained for the foreseeable future lol.

Thanks quad.

Glad you like it :)

Sounds like the 3.4 cutoff setting is perfect for you as a finished resting voltage of 3.7v is perfect. the difference between the 2 is the voltage sag you get near the end of the pack. Finishing on 3.7v rested is in the safe zone for storage so your packs should last well. If you are on FB, please share your painting in my group!

Unfortunately I'm not on facebook, but I'm tempted to join because of your group. Once I paint up the clear body shells and add a few finishing touches, I'll get a picture to you somehow.

Thanks again.

Now I'm wondering, do I put the same set up in my 124018 also, or try something different...... 🤔😁

I have a 124018 with a stock engine.
I use it 90% on a dirt track for rc with some friends, who we all carry wltoys.
For this type of terrain, which engine would you recommend?
I want to continue using the 2s batteries, maximize the duration of the battery as much as possible while maintaining more or less the same final speed, the speed can drop a bit I don't care.
I also think important point, I live in a very hot place and this chassis is a chimena hahaha.

Hi, thanks so much for this article. It convinced me to go brushless. I first tried with a all-in-one cheap kit in aliexpress but the motor which arrived was undersized (2435 / 4300kv with 35a esc). There was cogging and it would not run in grass.

I ordered a 80a esc / 3650 4300 Kv motor. It’s really impressive but too much cogging indeed.

Is the 2445 motor a huge improvement over the 2435 ? Would it run smoothly on grass ?

My brushes motor was eating the grass perfectly. I could do backflip going full power with the car sitting at the bottom of a wall. Would it be possible with a brushless setup? Or cogging would prevent it to happen?

Many thanks again.

Hi Ben. I haven't tried a 2435 in this car but have tried a 2440 and that's about as small as I'd go. I can definitively say the 2445 is a good option with the right ESC. There is no cogging with the ESC in this article.

Thanks! I love feedback like this! Great approach. I'd stick with the 3600kv motor and lower throttle dual rate on the remote if you want to slow it down - acts as a scaled throttle limit. That way you can crank it up when he gets better (or if you want to play). The 3600kv motor runs very cool.

I came into an issue with the hobby wing ESC you recommended - after a small crash the esc blinks red and jolts the motor during startup. It heats up the motor really quick when I hit the throttle, but does not run. I swapped the ESC to a suprass one, but it runs super hot after a few speed runs. It is possible that the heat from the defective hobby wing ESC damaged the motor and is now causing it to run hot with my suprass ESC? You have stated that it should be pretty cool in your comments.

Hi there. the 2838 4400kv is a larger more powerful motor than the 2445 3600kv however it does require drilling out the pinion to make it fit plus increasing the size of the holes on the motor mount. I hope that answers your question

Thank you!

They are very good motors and about the biggest i'd recommend for these cars. Personally I'd stay with the lower kV options. Stock pinion gear is 27t and I would definitely not run that. Personally I'd drill out the 15t to 3.2mm bore and run that if you wanted to use this motor with the Remo tyres on grass and dirt. You may need a bigger ESC than the one listed here. Consider the 2445 3600kv which is smaller but much easier to fit with no cutting or drilling required.

Hi,

I don't understand the pinion gear info. I ordered like in your blog the 2445 3600KV. This has a 2.3mm axle shaft from the motor. But what does the 0.7mm mean?

I have ordered the wrong one for this motor. And the local seller have 15T 0.8mm and 15T 0.6mm what could i best choose?

Reply
QuadifyRC
21/6/2021 09:33:29 am

Hi Henk

It's actually 0.7m which stands for 0.7 modulus - a measure of the gear pitch. Pinions in this pitch are very rare and outside of stock, only the ones I've linked here fit. Nobody stocks these outside of the Aliexpress seller I've linked.

Hi,

thank you very much for sharing your knowledge. I started with rc cars few weeks ago and it help me very much to understand how things are working.

Based on your article I bought the wltoys 124018 and modified to brushless setup with following components:

Racerstar 2445 - 5400 KV
WP-16BL30
FlySky FS-GT5
Pinion 15T

Motor is getting pretty hot, also in case of setting esc to lowest timing. So I decited to mount fan on it.

I changed the ESC settings 4. Start Mode to Level 5 and 8. Throttle Range to 6%.

I noticed a behavior which I could not find in your article or in the comments so I guess something is wrong with my setup.
When I was accelerating on stock setup, the throttle on my remote was very direct and sensitve related to the motor. But after brushless modification something changed. Throttle on my remote control is little bit less sensitive. It disturbes me, but I have no clue what the reason for it could be.

Any idea or advice what the reason could be?

Many thanks in advance.

Hi Kamillo

It's a little hard to tell what the issue is with words and it's impossible to share video here. If you are on FB have a search for my group. If your motor is still getting hot after all that, consider picking up a 3600kv variant. As well as the kV the way you drive and conditions you drive in have a big impact on current draw and heat.

Can you advice if i can run a 3S on this setup with no issues?

Hi there, thanks for the feedback. If you are going bashing I'd probably drop back to 3600kv which is still plenty fast but gives you more room to breathe. The 5400kv is VERY fast even on 2s but does run hot as a result. I recommend 5400kv on 3s for onroad straightline speed runs only. 110+ kph is faster than a car like this really handle other than a straight line only build.

Thanks again for the quick response. I will place an order via your hyperlink for a 3600kv motor but Bangood takes forever (I would also think it’s my lack of patience )

I however expect to receive the 5400KV motor this week so if I run that on a 2s with reduced timing will it break anything or burn the motor ? This will be my first ever upgrade and I want to follow your guidance to T.

Sorry for multiple questions and I sincerely appreciate what you do.

No problem mate, happy to help. The 5400kv is crazy quick, just keep an eye on the temps (and don't use larger wheels!) and you'll be fine. To be honest I am fine on 5400kv but i know some others struggled.

Dropping esc timing to 3.75 is a good idea :) The ESC will jump into thermal protection mode if it starts to struggle so there is a failsafe there.

The air flow problem is nicely addressed. I'm assuming you still needed to do this with the interior pieces removed, right? With the smaller motor physical size, were you OK with the X-brace in the flip- up top or did that/ should that be modified for more room? Stock Dean's connectors that come with the buggy seem to get in the way when closing the top. Do the recommended connectors help with that?

Hi,

I has the WL 124018 just a big month at home. I tried to drive it with the delivered remote but was very difficult for me, The only other RC car i have is a WPL D12. So it's all new for me. But a good reason to buy a remote and receiver. I bought a Surpass Hobby remote and with a Dumborc receiver with Gyro. Also i bought the Surpass Hobby 2445 3600KV with 35A ESC and metal gear 17g servo. And the 15T pinion you mentioned. And it runs great! I love the break function. I am a noob with this and makes it a lot easier. It goes so fast and i need to learn how to handle. And it hurts me sometimes the mistakes i made and see the car rolling a few times. But it's so robust! Nothing broken yet It's a really robust car. More than i has thought! Thank you for your tips.

I am considering the 2445 3600KV drop in brushless upgrade, for a basher (and also considering larger tyres, up to maybe 85mm dia). i was looking at the 2838 before, but got scared off when i saw some youtube vids of how easy it is to get the pinion drilling wrong. i noticed the 2838 3800KV motor on the facebook modders group, the one that has a 2.3mm shaft. wouldnt that 2838 3800KV be a better motor than the 2445 3600KV, have no disadvantages, only advantages? is there any reason why this 2838 wouldn't be the go-to "drop-in" brushless upgrade?

That 2838 3800kv motor from aliexpress looks like a good option although I have not tested myself. A friend who has tried both said they are very similar in practice (to the 2445 3600kv). The only reason I don't recommend is because there is only one vendor and little stock. The motor is an older design too but don't think that really holds it back. The 2445 3600kv is my favourite light basher setup by extension I'm sure that aliexpress motor would be good too.

It is lighter and smaller then your recommanded wheels. My problem is that with a new wheels I get thermal cut off after 3 minutes of running on 3/4 throttle. I lowerd timing on ESC to 3,75deg. After this cut off comes after 5 minutes. I run in the same condtions as on shock tires where I didnt have issue with the temperature. Another big disadvantage is running time, with new wheels I got 40% less then with stock :(

I suppose you are mainly running with non stock wheels. You dont have this issue? It is probably because better grip. I will probably have to stay with stock tires which are not good and have poor stamina.

Anyway thank you for your website, it is very usefull!

Hey Pete

I mostly ran the 5400kv setup on stock or slightly smaller wheels. When I switched to the 3600kv motor it gave me more options for larger wheels and so stuck with that. I like the 5400kv motor but depending on where and how you drive it does tend to run hot. I think if you have lowered the timing already then perhaps consider the 3600kv motor.

Hi. It looks like you really know your stuff! I just recently inquired a 12th scale (unsure of manufacturer) but its the Wild Challenger Turbo 2wd truck. It has (now has) all metal A-arms front/rear, metal axles and knuckles, brushless 60A esc & motor, I think factory rx but it may be a diy receiver. Originally servo and 5 wires go toward servo. The radio is a 2.4ghz M2R Racing. It was evidently running at one time and I have managed to get an output from esc to motor and it sounds mean! I am just wanting to get a quick recommendation to get it going again. If you need pics I can send. Thanks in advance, Dennis

Hi Dennis, thanks. Sorry not familiar with that model. If the controller say M2r it sounds like WL toys or a rebrand but I'm not aware of a 2wd model they make. If that is the case through they usually run and brushed ESC and receiver combined with an all in one servo. If yours is brushless that sounds aftermarket and all bets are off.

Hi QUADIFYRC, You're awesome!
Thank you very much for providing al your work en information. I've read and learned a lot of fun things here :)

I'm gonna upgrade my 124018. I use it for riding in through sand, forest, grass and speed runs on the streets. I am considering 3600kv, or even the 3000kv motor, but then with larger wheels. I would like to have more ground clearance, but also a good top speed. WHat wheel and kv motor do you recommend? What would be the speed in your experience?

Thanks again! :)

LOL thanks Yasin. You're in luck mate, I just finished a review on a new set of wheels that are brilliant for rough offroad, especially with this setup on 3600kv: https://www.quadifyrc.com/rccarreviews/144001-124019-124018-1822-wheel-upgrade-the-new-offroad-champ-some-compromises

You sir, you are awesome!

I've just finished the upgrade. Thanks to your guide it went really smooth. The car is so much lighter, I have to use the factory rear springs again, since I've upgraded them to heavier springs. The bugger grippy tires handle very well offroad.

I've used the Surpass Hobby KK 35A ESC to safe a bit money. I've mishandled a lipo with it. I suspect it doesn't have the cutoff on by default. The manual implies different, so watch it! Have to buy a program card now :(

Thanks again mate, have a happy new year and take care!

2440 motor is the smallest I'd recommend but would not trust an unknown ESC and controller like that. Here is the setup I'd recommend for 2440: https://www.quadifyrc.com/rccarreviews/144001-brushless-upgrade-the-cheapest-setup-worth-having

Hi Quad, great article, I've read it several times over the months. You said that you're going to link the Surpass Hobby version of the HW ESC, but you only linked to the 2 HW ESCs. Can you provide the Surpass Hobby link? Thanks!

Uhgg, why does Hobbywing use the dang Tamiya connectors on their smaller ESCs?! No one uses Tamiya plugs anymore, they were popular like 15 years ago though! The Quicrun 1060 brushed ESC I have has the Tamiya plug, so I had to get a Deans to Tamiya adapter. Does the smaller HW ESC that you used have a normal or mini Tamiya connector? I hope it's a normal sized one, or else when I convert my 144001 to brushless I'll have to buy another set of adapters!!

Anyway, little rant over, how does the 2445 5400kv compare to the 2440 5x00kv (I forgot the exact kv)? And how about the 2445 3600kv vs 2440 5x00kv? Thanks a lot in advance, sorry to be dumping all this on you! Cheers, and thanks again for all the good content, I've been reading this blog for over a year now!

I wholeheartedly agree - VERY annoying. Adding an adapter might mean problems later on. In addition to this problem, I used an HW Quicrun 1060 on my 12402 A and I lost top end. It's not like it's programmable as the only thing you can control is the type of battery and how you want the brake to operate. I'll bet I lost a good 25% of the speed the 550 brushed gives you. Contacting HW did nothing for me. A brushless setup is great for reliability, but for the kind of driving many of us do, the brushed system is good enough.

Probably my favourite aspect of the brushless setups over brushed is the improvement in efficiency but I think I'm getting old and boring.

Yeah, but I don't have a soldering iron or the skill to operate one! As I said, I have the same ESC as you! The reason why I kept the brushed motor and swapped the other electrics is because I stripped the stock servo in a crash, and later decided to just replace everything except the motor, as that would be easier in the long run and when going brushless. I got the JX servo, DumboRC radio/receiver, and the HW 1060 brushed, and I like it! So when I convert to brushless (after the brushed motor dies), all I have to do is get a B.L. ESC and motor, and the other parts to mount it and stuff.

I only drove my 144001 for about a month before I crashed and stripped the servo, and I don't go WOT (Wide Open Throttle), so I can't say if I lost top end going with the HW ESC, but with the HW ESC my 144001 is plenty fast. Could it be that the adapter you used limited the max current, which resulted in you losing 25% of the top speed?

I've heard that multiple people contacted HW about issues with the 1060 brushed and they didn't get responses either. Strange. For me, B.L. is appealing because it makes my car significantly lighter, less heat, and a little higher top speed and battery life, but the last two are pretty good right now with the brushed motor (my average driving speed is like 25%, I'm a more careful driver lol).

Yeah this connectors sucked in the 90s when I ran them and given the more powerful batteries they are plain stupid now. Mini tamiya on the 16BL30 I'm afraid. Please cut and solder new connectors because adaptors still have big resistance in them (electrical circuit only as good as the weakest link).

I've only tried the 2440 4600kv option. Good motor but you'll need to keep your car light. 2445 are great motor but the 3600kv is a little low and the 5400kv a little high. 2445 3600kv is really reliable and efficient and perfect on 3s. Thanks for the kind words too.

I still really am stumped why HW uses this connecter on only this ESC...

I 100% agree, adapters aren't ideal and the amps/current that a mini Tamiya connector can handle is probably like a joke. Thing is, I don't have a soldering iron or the other bits and bobs like tin, heatshrink, ect. and nor do I know how to solder! I do want to get an iron and learn how to use it sometime, but I don't want to do all that just to change the connector from mini Tamiya to Deans. Maybe my LBS will do it for a good price, but I haven't actually visited a hobby shop before lol!

I found these two combo packs on BG, the first one comes with a servo, ESC, and a 2445 motor. The second comes with a 17g servo, ESC, and 2440 motor. Would any of these deals be worth it? Mainly, are the ESCs good? If they are, I could get three electrics (though I don't need the servo, but may come in handy in the future) for ~$30!!

Option 1: Damn, it seems that it has disappeared from the website completely!

Option 2 (2440 4600kv): https://www.banggood.com/Surpass-Hobby-KK-2440-4600kv-Brushless-Motor-35A-Brushless-ESC-3KG-Digital-Servo-Brushless-Set-for-1-or-16-RC-Car-Model-Parts-p-1753848.html?akmClientCountry=America&

Also, how about these 3 ESCs, are they good for running a 2445 5600kv in my 144001 on 2s?

ESC 1: https://www.banggood.com/SURPASS-HOBBY-KK-Waterproof-25A-ESC-Electric-Speed-Controller-for-RC-1-or-16-1-or-18-1-or-20-RC-Car-2030-2040-2430-2435-2440-2445-Motor-p-1772570.html?cur_warehouse=CN&rmmds=search

Issac, I didn’t use an adapter on my HW1060, I soldered on a Dean’s connector. I’m living with the reduced top end. It just bothered me to lose it with a top name ESC. I have cheap no name brushed ESC’s I’ve gotten off of EBay and they’re fine. They even came with cooling fans mounted.

Could it be your Deans connector, maybe it was worn out? Or maybe it's your battery, and, I know you probably already checked this a million times, but is your throttle dual rate turned up to 100%? Are the motor wire connectors fully plugged into the ESC's wires? If you can't reply to this reply, just reply to any of the other comments in this thread.

Great article, thanks much appreciated by a newbie to the hobby. I've ordered all, the exact same parts bits except I went for the 3600 kv motor option. I was wondering for the 124018 is there any way to power the lights from the hobby wing Esc? also is there a 3s battery with T plug you would recommend? thanks.

3600kv is the my favourite choice for offroad. You can power the LEDs from a spare channel on the receiver, just need to change the plug to a servo connector. Bear in mind that the black and red wires are the wrong way around in this car! No 3s batteries in this size that I've come across with t plug sorry.

Ordered everything for my 124019 and i Was wondering if I can use 3s for top speed runs just a couple of times or will it fry my motor?
Using the 5400kv motor and the cheaper/waterproof esc.

Hey!

Thank you for answering!
Build went more or less well. Had to drill out 2 screws and install new gear on motor twice since I didn't notice that flat part on first time.
Overall it took me 9 hours to get it working properly (first rc car 124019 and my first build). Your guide was big help to me!

Hi there, I am using the Surpass-Hobby 17g Metal Gear servo in this build on a 124018. It seems a slight bit smaller( i.e less than a mm or so in both directions) than the stock one and seems to move about when screwed in. Any tips for making it more secure? many thanks,

Great article! This really helped me taking up a new hobby.

I really like the 3600kv option on 2s, im getting old too ;)

But on 3s with the 16bl30 esc im having some issues. The low voltage cutoff kicks in at 3.5V instead of the set 3.2V. In do hear 3 beeps when turning it on so it does recognize 3 cells.

I tried setting it manually since the manual reads that it’s preferable for 3s. But the program card skips setting 11 and 12.

Do you maybe have some pointers. Would be much appreciate.

I'm looking for some advice as to whether I can run a 2845 4300KV with the Hobbywing QuicRun 16BL30?

I was successfully running this motor (2845 4300KV) with a surpass hobby 60A esc in my 124019 with 15T pinion and the Remo tyres. I then tried running a 2445 5400kv and managed to set fire to the esc after about 5 mins bashing in a car park, despite modifying the bodyshell to improve cooling (and it wasn't a warm day).

I've now bought the hugely impressive hobbywing QuicRun as a replacement. Will this esc run my 2845 4370KV?

I'm also a little nervous about running the 2445 5400kv but have just read the article about adjusting the timing. I just don't want to break my new esc by running the wrong motors. Some reassurance would be good. Thanks

Hi Ian. Yep should be ok but it's at the top end of it's capabilities. You'd need to run a 15t pinion and be wary of big wheels but otherwise should go great.

It can run the 2445 5400kv but strictly on road with stock or foam wheels. Just too much current. It's bloody rapid though!

Hi Ian

Depends on how you drive but if you are running the 2845 4370 with a 15t pinion on 2s you should be ok in general. Check in on temps and consider adding a fan to the ESC. I am using a 3900kc 2845 at the moment on 2s with a cheap surpass KK 35a esc and that is fine (for me).
