Recently I upgraded to brushless power in the WL Toys 144001 as you can see in the below article which is also relevant to the new WL Toys 124018 and 124019: WL TOYS 144001: ULTIMATE BRUSHLESS UPGRADE GUIDE Performance is so much better than stock and battery life has increased by over 50%. I much prefer this smaller brushless that the larger 3650 size that are usually limited to on road and speed runs. The install is fairly straightforward but you need to slot the motor mount to set the mesh on the smaller 17t pinion gear and this can be tricky. Good news though, I've found a workaround where no machining nor tricky gear mesh setting is required. The 144001 uses a 0.7 modulus gear pitch and is very rare for pinions. We are typically limited to the very large stock 27t pinion (way too big for this application) or the 17t pinion from the WL Toys A959 / A969. The 17t pinion offers an excellent ratio for the 2838 and 2845 motors but you need to mod the motor plate as mentioned in my original brushless upgrade article. Good news though, I've found that using the stock 380 motor mounts on the motor plate you can use a 15t pinion gear. Up until recently these have been impossible to find but I've done a LOT of testing and have found three options for you.
Option 1: 15t from Hobbyking Hobbyking still have some old stock of a 15t 0.7m pinion that we used on certain helis but it is not a bolt on option - as it has an oversize 5.0mm bore. Because of this you need a 5mm to 3.2mm reducer which is available here. You may also need to file down the grub screw a little if it fouls on the mount. Please note this may now be out of stock depending on warehouse
The larger bore means the pinion collar is larger. It fits but the grub screw needs reducing in length just a little. Option 2: 15t from Aliexpress 2.3mm bore This pinion is a nice fit but you will need to increase the bore of the pinion from 2.3mm to 3.2mm. This can be done easily with the appropriate drill bit such as this cheap 3.2mm bit option here. The other option is to run a motor with a 2.3mm shaft like the one below. If the above link isn't working try this link for 15t pinion
This is what it looks like in the car and what I am running presently. Virgin motor mount with no slotting! Option 3: 15t from Aliexpress 3.2mm bore This option will bolt up directly and requires no modification whatsoever. They are a little more expensive because I think they are a specialist item but no mods are needed for this whatsoever. Make sure you choose 15t and 3.17mm Update: Although the pitch is correct this pinion is too long as reported by a user. Unfortunately mine was lost in the post before I could confirm. I'll work with this supplier to see if they can make a bolt on option but at present I would recommend the above 15t gear and drill out the shaft. This should be the minimum work option but is the most expensive. I've ordered one to try but have not yet received. Will report back here once I have confirmed it is working as expected. Update, see above note. Performance Final mesh is just a little tighter than I'd like (although 14t is too loose after extensive testing). It does settle down after less than half a pack and I can now feel the the backlash is spot on. Understandably top speed is a little down on where the 17t was but still faster than the stock motor. acceleration is bonkers and due to the relatively low load on the motor battery life is crazy, even on the stock 2s lipo. Given this is little under-geared, it really opens up the opportunity to run 3s where this should be capable of fairly ludicrous off-road speed. I want to do some more testing in this space around durability so please watch this space and I'll update later on with my experiences. Update: I'd recommend sticking this 2s - although I've not burnt out running on 3s there seems to be a 10-20% failure rate with extended running. The shorter gearing also allows the use of slightly larger wheels such as the excellent P6973 wheels and tyres I detailed in this wheel upgrade guide. Final recommendations Although the 17t pinion is probably more suitable for the 2838 4500kv motor I'm running, it takes a lot of work and fiddling to install. Using the one of the 15t gear options I've recommended above will make it a little slower but the install is so much cleaner and probably more robust in the long run. It also makes it more viable for a 3s battery upgrade for some serious power. All in all I'd recommend this over the 17t as per my first brushless upgrade article not because of the out and out performance but because of ease and long term durability. More power? Yep. More efficient? Yep. Longer life? Yep. Lastly, check out the difference in weight... Summary of the full recommended parts list to upgrade the WL TOys 144001 from stock brushed to 2838 brushless:

Thanks again for the awesome guide! I’ve just upgraded mine using your guide. As I had just received the AliExpress 15t pionion, I have used that one. I used a cheap handsaw (metal) to shorten the pinion about 2mm. As the cut surface is in no way critical, that seemed fairly safe. Tomorrow I’ll give it a test run. Side note; The finishing on the pinion teeth seems fairly rough, lets hope it doesn’t chew through the spur gear!

So after a few weeks running the option 3 pinion seems to hold up well. Given how easy and fast the hacksaw cut was, I’d actually argue this is as good an option as the others in the article!

Hi Bjorn, running a big set of wheels like that changes the effective gearing a lot. I'd recommend dropping down the kv to around 3800, stock with the 2838 or 2845

I use a 2845 3800kv motor with 90mm wheels, the MT ones, and the 15t pinion with a hobbywing 120 esc. It runs perfectly with no overheating and pretty fast off Road too. When using onroad tyres (65mm) its slower, but has lots of Torque. Im very Happy with It.

Hey Eric thanks for the kind feedback, I really enjoy helping people like yourself and getting people hooked. The stock motor is a high wind 550 which puts out a huge amount of low rpm grunt in a car this size so the manufacturer made the gearing tall to get a big top end out of it and brag about top speed. Practically every replacement brushless motor has a lot more speed but a lot less torque at low rpm. Changing the gearing allows us to take advantage of the characteristics of these motors which are superior in every other way.

Hey guys, I know im a bit late to the party but wanted to chime in on this as i have recently picked up one of these 144001's. I just completed a brushless upgrade on the car along with upgrading to steel spur and pinion (stock gearing). The motor/esc combo was a cheapy from amazon(goolrc) 3900kv with 60 amp esc. It coggs like crazy...until you get it going...then its a rocket. The motor size is 3650. I stayed with that size due to the limitations of the stock mount. I recently contacted Castle Creations for a recommendation...they recommended their new copperhead 10 esc(2s to 4s compatible) and 1406 2850kv motor combo due primarilly to the tall gears. The tech said i should see approx. 65 mph on 3s. Also, its a sensored motor and esc so no cogging. Ive yet to install but am hopeful this will be the cure without major surgery. Great site. I hope this helps

I recently picked up my own 144001 and I am so glad that I found your blog. Thank you so much for all of the great info on your site, for an adult RC noob like me, it is true gold! Unfortunately, I had already ordered a 3650 brushless motor/60a esc combo based on youtube videos but now I am wishing I had gone with a smaller setup because I will be mostly running off road and in my backyard. Please forgive my dumb question, but is there anything I need to do if I go with option 1? Seems like I just need that 15t hobbyking pinion and the adapter. Do I need to cut or modify any of the parts to have for success? Thanks in advance!!

Argh sorry I missed your comment, my notification system is a bit hit and miss. Thanks for the kind feedback. Option 2 is my strongest recommendation but does require increasing the pinion bore from 2.3mm to 3.2mm (1/8"). I used a vice and hand drill but a drill press if preferable. If you can get an engineering shop to do it that would be best. Beyond that I think I trimmed the plastic gear cowl just a little but considering the alternatives like slotting the motor mount this was much easier. Best of luck!

Very detailed article and mods but I worry that people will convert to brushless and the 15 tooth pinion gear will no longer be made as is the case with several 1/18 models I have. Hopefully this craze will cause the manufacturers in China to produce a brushless version and available parts and we will have a path forward for longer term.....Right now I'm trying to figure out how to solder silver solder on an old pinion and modify a discontinued spur gear as well as make my own dogbones.

Hmm that's a good point. Given the mounts for the 2838 on the stock mount they must have had plans some-point for a motor this size. My guess is they started with a 380/390 but abandoned it when they realised they could shoe-horn a 550 in. I might write to WL toys to see if they could comission a proper bolt on option in 2838 size. Personally I think the next effort should go into making an aftermarket spur fit as you say, then you'd have access to the more common 48 or 32 pitch gears which are cheap and plentiful

Just finished the option 1 upgrade yesterday and the car runs great! It was a little tricky getting the hobbyking pinion mounted properly so that it would not rub against the motor mount but everything else was super easy. This setup is way better all around than when I was running the 3650 brushless setup.

Awesome David that is good to hear. The 2838 is a very powerful motor. I genuinely believe this is a better option in 90% of cases for the 144001. The only way the 3650 is better is for speed runs which are frankly a little boring for me.

Hi Quadify! After reading all of your posts about the 144001, I decided to buy one as my first RC Car! I'm so excited to learn all about it. Do you know what exactly would happen if I were to use the stock gearing with the 2838 motor? If I were to keep the stock gearing, is there a brushless motor/esc that would be better suited? Thanks so much and keep up the amazing work.

Hi thanks for all the hard work in compiliing this guide, my bits are on the way.

Unfortunately a lot of the others Chinese retailers bait and switch which is why I give direct links to Banggood who are at least fairly accurate. Cogging at low speed is a sign of either poor connection or a low quality ESC and or motor. Assuming the programming card works you could try increase timing but stock setting from the factory are usually the most reliable. Afraid I can't help on this one.

Hi QUADIFYRC, you're site is a priceless resource. Well done! I'm wondering how the balance of the motor feels with the pinion + sleeve option? Reason I ask is, and correct me if I am wrong, the sleeve is fixed to the shaft with a grub screw and the pinion is fixed to the sleeve with a second grub screw. My thinking is if the grub screws are *not* 180 degrees out of phase then it may cause vibrations. It is probably a moot point, but interested in your thoughts. Cheers.

12/2/2021 10:37:13 am
Yikes completely missed your message! Thanks kindly for the feedback. It feels ok, the fit betweem shaft/pinion/sleeve is very good with no real wriggle so the force trying to make the pinion fit concentrically on the shaft is pretty small. For a racer you'd be looking to squeeze everything out but as a basher it is more than acceptable for me.

Took it to a nut and bolts shop. They measured and said it’s M 3.0. However, in trying to get the bolts through the holes in the mount, it got threaded, thus causing it to tighten only the mount instead of the engine to the mount. Solved it by drilling the holes with a 3.0 bit to clear the thread in the mount.

To be honest the smaller 2838 motor with 15t would run cooler but if you want to run 3650 I'd use around 3000kv with the stock pinion. You'll need a reasonable ESC to keep cogging down though

I might go for the 5100kV 2838 w/15t to aim for a similar top speed as the 2445 suggested build, but am tempted by the 5700kV 2838 option too - is that viable with the 15T pinion?

Hi Joeke, my pleasure! Yes undergeared = more torque and less top speed however it is still faster than stock and gives you massive runtime, roughly double compared to stock.

Hi, So I have my 144001 on order which should arrive tomorrow and have already ordered the parts needed for the 17t brushless upgrade, however since ordering the parts I have found this 15t option which seems like the option I should and would prefer but can not find the 15t pinion gear anywhere that will ship to me here in the UK. Is this something you maybe able to help out with?

Hey mate, I see people are getting about 50kph with the 2838 4500kv and 15t pinion. Would this setup have much more torque/acceleration than stock. I’m looking at using the hobbywing 30a esc. Also could this setup run on 3s and how quick do you think it would be?

Hi Mark. Way more acceleration, torque and about double the battery life. It feels much faster because of this too. Sadly my car was stolen before I could GPS test it but I'm certain it was noticably faster than stock. I wouldn't run this on 3s with this ESC, google the drop in brushless upgrade if you want more speed than this.

Hi quadifyrc! I want to make my 124019 a good bashing machine. Im not into speed builds and i dont need It to be faster, just more efficient and cooler. Can i put a 3560 3100kv motor with the 17t pinion and keep It cool and ¿Will the battery last longer? Can you advise me on a 3650 motor for offroad? Dont need It to be crazy fast. I have a adjustable 3560 motor mount to move the motor the way i need, si the pinion option is no problem. What do you think Will fit in better? Pretending to use 76/80mm diámeter wheels.

For bashing I recommend a smaller motor as the big 3650 is heavy and upsets the weight balance. The easiest install is the 2445 3600kv as per my drop in brushless upgrade. This is a very good reliable setup https://www.quadifyrc.com/rccarreviews/drop-in-brushless-upgrade-guide-for-wl-toys-144001-124018-and-124019-quadifyrc

I'd go with the 2445 3600kv. However if you are a very confident builder then consider the 2838 which has a little more torque

One last question, i promise. Im a confident builder and ill buy the 2845 3800kv motor paired with the Big 10bl120. Will i be able to use this?

90mm is getting a bit big. Even on the 15t your motor will get a bit hot in 2s. I'd recommend these instead: https://bit.ly/3m9TlkU

@QuadiftRC, will this pinion work with 2838 motor now that the hobbywing 15t options are sold out. I know I would need a reducing sleeve for the shaft, just wondering about pinion dimensions and tooth count if it will be too small. Thank you!

Hi David. It will mesh but getting the pinion to fit in the mount with the wider collar is a pain let alone the fact that you would need to slow the motor mount because the 14t is smaller. I'd recommend getting the 15t from ali express and drilling out if you want to stick with 2838 or consider this option where no drilling is needed https://www.quadifyrc.com/rccarreviews/drop-in-brushless-upgrade-guide-for-wl-toys-144001-124018-and-124019-quadifyrc

Oh really good to know, thanks for getting this info back to me. I didn't know about your new drop in method, I will definitely go that route.

@QuadiftR, hi, i am trying fot the no drill option with the 15t pinion,

Anyone trying the 15 tooth pinion no drilling required from Ali express, be warned that the quality is terrible. After one session on the stock plastic spur it wore the pinion teeth down to unusable. They were available in two metal types, but I think I will just drill out the other option after waiting 15 days for a pinion that didn't last 1hour.

I have seen some slight cogging at times, and the initial takeoff is slightly delayed from the throttle opening. The worst situation is when trying to go forwards when the car is rolling backwards slightly: it doesn't respond very well to the throttle, although it improves with more throttle opening. One thing that the brushless motor was always good at was its instantaneous throttle response, so I do miss that with this brushless setup. Have you tried a sensored motor setup?

With the 15T pinion on the original motor mount bracket, the gear mesh with an upgraded metal spur gear is on the loose side, so that was a surprise, given that yours was tight. It creates a bit more noise that the original. I'll keep an eye on teeth wear, to determine if I need to adjust it.

An unexpected bonus is that the steering servo that you recommend works much better than the original. It has more torque to ensure that full steering lock can always be achieved. The car originally would not turn sharply at speed, making me think that a handling issue had the car understeering, requiring the throttle to be reduced to help the car turn. This new servo shows that actually the original servo was not strong enough to maintain steering lock against the steering self-centering forces under high throttle loads at high speeds. Now the car can turn so sharply that it can get up on two wheels, or roll over, so it has to be driven more carefully. This is with LC Racing anti-sway bars fitted too.

They might fit but all I can say for certain is that the only confirmed fit I am aware of is the 15t I linked in the article

so if i was to have found a motor mount with slots instead of holes(for mesh adjustment) could i use any tooth pinion i wanted. also if i was to change the drive shaft gear to a mod 1, would that solve most of the main issues that arise with switching to brushless?
Reply
QuadifyRC

Yes, but the only motor mounts that are slotted fit the 3650 which is fine for speed runs but not general bashing where the smaller motors are better. Moving to mod 1 creates other issues particularly around the lack of hanger bearings.

Just been on Aliexpress to order some 17T gears for this upgrade and noticed that the motor mount and 19T pinion are on sale from the 124016 & 17 v2. I guess this too would be a 'no cut' upgrade and the pinion probably won't require drilling out.

Yep that would work. Personally I'd pair the 19t with 3400kv but would still prefer higher kv on 15t
