LC RACING LC12B1 Build Guide

18/9/2021

24 Comments

 
Our regular contributor Geoffrey Chan is at it again, this time with a very detailed build guide for the LC Racing LC12B1. This is a fantastic 1/12 4WD buggy from LC racing that comes as a kit. These cars are well priced (for a race car) and are highly competitive in carpet racing.
Picture
​I will start by saying that I’m a big fan of LC Racing RCs. It was just a matter of time before I finally pulled the trigger and picked up what is essentially the King of 1/12 scale 4WD buggies. I’m quite confident that there isn’t a better engineered buggy in this scale on the market today. Make no mistake, this is not a budget RC. Although not as expensive as larger 1/10 scale buggies, it is still more than 2x the cost of a WLToys 124019. Even up to 3x the cost depending on what electronics you decide to put in. What you get for the extra dollars spent on an LC12B1 is better material quality, much tighter fit and finish and overall better tolerances. It should also be mentioned that this buggy’s dominance is not at speed runs, but at quick acceleration, jumping and cornering. If speed runs are more your thing, then modifying a 124019 will get you more bang for the buck. That hasn’t prevented others in the LC Racing community from building theirs into a speed runner, it just wasn’t the intended use or design and where this car truly performs and rules.                 
Picture
The LC12B1 is available from the following retailers:
  • B anggood here 
  • Aliexpress here (this is the only vendor here I recommend)
  • LC Racing.Net here​
I want to point out that the chassis length between the LC12B1 and all models of the LC Racing EMB line with the exception of the EMB-1 and EMB-MT are all the same. Yes, it’s a bit confusing that the 1/14 cars are the same size as a 1/12, but that’s just how they’ve decided to differentiate the product line. The WLToys 124019 and 124017 are also same size and length as the LC12B1 and as a result, several of the suspension and body components are compatible between the models.
Picture
The LC12B1 is only available as a kit that requires full assembly down to the last screw and paint for the body shell. I opted for the kit that doesn’t include any electronics except the Batan digital servo as I wanted to spec out the motor, ESC, transmitter, and receiver. The major differentiator with the LC12B1 from the other LC Racing EMB 1/14 scale line-up and WLToys 12401x line-up is that it is a mid-motor architecture. This helps improve weight distribution towards the front of the car for better balance and handling in turns as well as when jumping in the air to better level out for landings. Pretty much all competitive racing 1/10 scale 4WD buggies are a mid-motor design.

​All the pieces come clearly labelled in individual backs to facilitate assembly. Throughout each section of the instructions, it will refer to the bag required to build out the car one section at a time.

What’s included in the kit:
  • 1/12 LC12B1 4WD Competition Buggy
  • Pre-mounted off-road buggy wheels and tires
  • Front and rear anti roll bars 1.0mm, 1.2mm and 1.5mm.
  • Batan D115F Digital servo
  • 60T Spur Gear and 17,18.19T pinon gears
What’s not included in the kit:
  • Transmitter and Receiver
  • Battery
  • 380 size motor
  • ESC
  • Differential Oil
  • Shock Oil
  • Paint for lexan body

This is the first kit RC that I have ever built, but given my experience taking apart and reassembling my WLToys 144001 and 124018, the entire process is very familiar. If you haven’t ever built a kit before, this is really a good experience to get intimate knowledge of how your car functions mechanically, electronically as well as how all the pieces come together so when there is an issue, troubleshooting is much easier.

​I will take you through my build process as well as my parts selection and point out what are in my opinion the key areas that make this the King of the 1/12 scale 4WD buggies. I should also note that the LC12B1 is engineered to be a race car to turn fast laps at a smooth dirt track or an indoor carpet track. However, not having access to either of these facilities, I am building out mine to be more of a tarmac racer, which just highlights how versatile this buggy can be. 
Differentials
Going through the first section of the build is the assembly of the differentials. Three things immediately stood out to me. First was the absence of any shims in the kit. However, because the tolerances for the parts are so tight, there was minimal play and were unnecessary. Second thing I noticed were the hardened metal gears that will help ensure the diffs were reliable and tough for hours of driving. Not all metal is created equal. Third thing was there are silicone seals in the diffs that require the use of specific silicone differential oil to be used. The great thing about being able to use silicone oil in the diffs is the added tunability with different weights that affect how the car handles in turns and on power. Without oil, power would simply push to the wheel with the least resistance and cause it to spin. Adding oil reduces this spin and greatly helps with traction. The seals are a feature that is lacking in the WLToys differentials, which is why sticky, thick grease is often recommended instead of oil as it tends to stay in the diffs better over time.
Picture

I opted for a 7000wt in the front and 3000wt in the rear. Using a thicker 7000wt oil will help through turns while on power while using a thinner oil in front will help with turns while off power. This may not be the perfect set up for me, but it’s a setup I’ve seen a lot of LC Racing owners have used, so I figured it would be a good baseline to start with and further tune from there. 
Shocks
The next section of the instructions tackles the assembly of the shocks. First off, this kit includes the friction reducing Ti-Nitride coated shafts, which is often something you see on the high-end 1/10 scale or bigger race buggies to smoothen the suspension movement. This is included as a standard item in this kit, which is pretty sweet feature that adds a bling factor. Not sure it makes much difference as my EMB-T shocks don’t have the Ti-Nitride shafts are still very smooth. The shock assembly is a straightforward affair. LC uses a set of C-clips to hold the piston to the shafts, which is more solid than the single pin design on the WLToys shocks. Take note as well the shocks use a dual silicone seal to minimize any fluids from leaking out. I filled the shocks with 35wt in the rear and 30wt in the front as a starting point and will tune and adjust from there. The Stock RTR LC Racing cars normally come with approximately 25wt oil for comparison.

​Keep in mind if you are building this kit that the front shock body and shafts are slightly shorter than the rear. Don’t get these mixed up or you won’t get the proper stroke and height on the shock. Don’t ask me how I know… I also took this opportunity to slip on a few animal balloons on the lower shafts to keep dirt out of the seals to prolong the service life of the oil shocks.
Picture
Picture
The kit also includes different sets of front and rear springs with increasing thickness/stiffness to fine tune for the surface you will be driving on. I decided to start with the softest setting and would increase as needed. I will be using the car mostly on outdoor tarmac. The stiffer the spring, the better it will be for smooth tracks such as an indoor carpet track. Even the softest springs is stiffer than any of the stock WLToys springs that come on the 144001 or 12401x models.
Picture
Suspension
​The assembly of the front suspension assembly starts with the hubs, hub carrier, CVD’s, lower diff housing, suspension arms and a completed diff. There are a few notable nice features that are included in the kit. The wheel hexes are the signature LC Racing alloy hexes that have a grub screw to hold them in place on the CVD’s to minimize any play and wheel wobble. The arms that are included are the thicker and stronger “hard arms” that are normally an upgrade item for the other LC Racing EMB 1/14 scale cars. Also take note of the hex screw hardware all around comes standard is of much stronger metal and is less likely to strip. I made the decision to upgrade the hubs and hub carrier to the LC Racing alloy units for durability. As I plan to be doing a lot of tarmac driving on the streets, the chances for a bump into a curb at speed is quite high. 
Picture
To finish assembly the entire front suspension, greasing the diff crown gear and screwing down the upper part of the diff housing makes the rest of the build easy. The following step is to attach the included sway bar set to the diff housing and the swing arms, which is an easy affair. It is typical to see a sway bar set with race pedigree buggies. I chose the medium setting for front and rear to test and will test from there for handling feel. QuadifyRC has documented a detailed how-to on the 144001 in his article and it is a worthy upgrade for the WLToys 4WD buggies.

​The last step is to mount the alloy shock towers, shocks and turn buckles to the assembly. One trick to note for the turn buckles is to put a small dab of grease on the threads to make turning them much easier when they are mounted on the car. The WLToys turnbuckles are notoriously tight and difficult to turn and doing this step will make fine turning toe and camber much easier.
Picture
​Assembling the rear suspension and differential is basically the same as the front. Also, a big plus with this kit is that is employs the same hardened CVDs for the rear as well as the front. What you will notice is that it is required to fully close the diff housing and attach the diff bevel gear and outdrives for the center driveshafts. This assembly approach is not possible on a WLToys due to the solid driveshaft design with the bevel gear attached. Because LC Racing uses a floating driveshaft design, it makes mounting and removing the entire assembly for servicing much easier in comparison. 
Picture
Servo and Steering
From this point, it is time to start mounting the servo, servo saver and suspension posts to the chassis. The kit includes a Batan digital servo that has plastic gears. It is possible to upgrade to a metal geared version, but the included unit works well enough, but is not as quick as the Surpass Hobby S0017M. I am looking for a way to the quicker and inexpensive Surpass servo in place of the Batan, but because it uses a two-screw mounting tab, this makes it a bit tricky to find something in the same size that fits the stock mounts. Small detail is that the servo saver comes with an red alloy arm. Not sure why only that arm, but a nice upgrade over the EMB line-up’s plastic.
Picture
Picture
Motor Mount and Slipper Clutch
The motor mount and slipper clutch support are next to be mounted. The alloy used is nicely anodized, but more importantly is stiff and quite solid. It is an adjustable design and can accommodate between 16t to 22t pinions with a 0.5M pitch. 
Picture
Picture
With motor mount and slipper support attached, assembling the slipper clutch and installing it is required next. A slipper clutch is a big advantage when sending power to the wheels to help absorb shocks to the differentials due to sudden throttle inputs. It is also there to protect the drivetrain when landing a jump or when a sudden reduction in speed of the wheels sends a stopping force through the drivetrain. It is essentially a spur gear with a friction pad material pressed in with a spring for tension. It is possible to adjust for tension based on your preference and level of traction control needed. This is an important traction and protective feature and is absent from any WLToys models. Another place where the added costs has gone into for the LC12B1.
​
At this assembly step, it is necessary to install the center driveshafts which are effectively dog bones that connect the entire driveline together. Those with keen eyes may notice that the WLToys 104001 borrows quite heavily from this design, but upscaled to a larger 1/10 size and without the slipper clutch.
Picture
Picture
Electronics
The next piece is the electronics. I opted for a motor that isn’t commonly used in the WLToys community, but it was David Wong’s track prepped 144001 that influenced my decision to try the sensorless, brushless Tenshock X1401 in a 5150KV spec. The 29mm x 37.5mm can size of this motor is different from several of the more commonly sized brushless motors, but don’t let the small size fool you because this motor is potent. It is every bit as comparable to the LC Racing 2850 sized motor. The magnets feel stronger than any of the other 28xx brushless motors that I have in my collection. The compact size is also saves space and reduces some weight. Although twice the cost of a Surpass Hobby 2845 motor, I really felt this car deserved a special power unit. I have also seen many LC community members rave about how smooth and powerful it is and had to try it for myself. A nice detail with the Tenshock motor is that it comes with 3.5mm bullet connectors for you to solder onto the ESC. This came in handy as the Hobbywing Quicrun 10BL120 only comes with leads
Picture
Picture
Picture
I opted to use the largest 22t pinion LC Racing supports on this initial build instead of the 17t, 18t or 19t that is included in the kit. I will continue to adjust and tweak with my gear choice as I get more driving time in. Did I mention how nice it is to have the ability to swap out pinion sizes for tuning for your terrain and driving conditions? 
Picture
​With the motor mounted into the chassis, I was able to mount the carbon fiber top deck support. I also put in the carbon fiber battery tie down in place. The use of carbon as a standard material for this kit takes the quality factor up a few notches and adds a bling focal point in the chassis. Not only is carbon light and stiff, but it looks bad ass in the car. Take note that I ordered the optional LC spur gear cover to protect my wires against any accidental mishaps. It’s a shame that this isn’t a standard item in the kit. A clever LC Racing community member recently shared a 3D printable design on Thingiverse.com if you have access to a 3D printer. 
Picture
The ESC install is the next step. I chose the Quicrun 10BL120 as it is a favorite choice in the WLToys as well as the LC Racing community for the price point and performance. A 60A would have sufficed with the Tenshock X1401, but because the price difference between the 60A and 120A is so negligible, I decided to just get the higher rated ESC. I used the vice grips in the picture to hold the bullet connectors in place while I soldered. Pretty helpful if you don’t have a set of third hands. I pre-fitted the ESC and market off on the spaghetti long leads where I wanted to cut and made the connections. If you haven’t already, be sure to check out QuadifyRC’s article on soldering for tips on how to get better at this skill as it is a must have if you plan on staying in the RC hobby
Picture
To optimize for weight balance in the car, I mounted the ESC in front of the motor to keep as much weight in the middle of the car as possible. With the ESC mounted, I also installed the Flysky 4-Channel FS-A3 receiver on top of the Batan servo. Everything fit in nicely with the antennae fed through the included piping to protect it, ran along the top deck. This takes care of the electronics for this build. 
Picture
Picture
Customising the body, wing, bumper
I installed several other LC Racing options parts to this build. A front bumper for me is a must to save the front end from unexpected impacts. I’m running this car outdoors and, in the streets, and you just never know when a bit of added protection will prevent a breakage. The LC EMB-MT is a go-to for me for price point as well as looks.

​I also, decided to use the LC EMB-T wing on this car instead of the Lexan one that comes with the LC12B1 kit as I didn’t feel that I needed the level of downforce that wing generated and it is made of a sturdier composite plastic that would hold up better in an impact or crash.  The original wing is HUGE and is the same size as the one that comes on the WLToys 104001.
Picture
Instead of the stock disc buggy wheels and off-road tires, I wanted to test out the LC Racing EMB-WRC wheels and tires. The diameter is similar at 65mm to the stock off-road tires, but the tread pattern is not as aggressive or wide. I also wanted a different look, and these fit the bill nicely.
Picture
Picture
The last and final step to this build is the body shell. I do like the low profile look of the LC12B1 body, but I have been seeing the Phat Bodies Hammer on so many builds in the community that I really wanted one. The higher profile shell also makes it easier to fit over the electronics and wires and provides a bit more airflow for cooling. I have never painted a body shell before and knew I wouldn’t be able to get a decent result on this beauty of a shell with more than one color. I decided to do a base black paint underneath and used vinyl wrap for the other colors. Using light grey for the lower part of the body and shifting to a matte pearl white it gave the intended look. The red stripes finished off the Honda Type-R inspired color scheme nicely. The most difficult part was to mask the clear window area. It isn’t obvious in the photos, but in person upon close inspection, the line isn’t as clean or crisp as a pro paint job, but it turned out decent enough for me to be happy with it for my first time customizing an RC body.
Picture
Picture
​Cutting the excess long the bottom of the body as well as the openings for how it will fit around the chassis was a bit tricky but made much easier by a set of proper RC body cutting scissors. The length and curved cutting edge made it much easier to make rounded openings. I also used the stock body’s opening guides as a reference for where and how large an opening to cut. 
Picture
Battery
The only thing left to do is to connect the battery. This is probably the only major downside to this platform. Because the spur is exposed in the mid-motor design, it is critical the battery is secured to prevent it accidentally moving and hitting the spinning wheel of fire. The carbon battery tiedown solution is not the best as it requires you attached your battery to the plate with two Velcro straps and then it is secured to the chassis with two M2.5 screws. This will get old pretty quickly.
Picture
I’ve since ordered thumbscrews to make the task a bit easier without tools. The other issue is due to the limited space, there are only a few battery sizes that can fit in the spot. The maximum size that would comfortably fit in the stock configuration is a length of 90mm, a width of 35mm and 20mm in thickness. I was lucky that I had a pair of HRB 2200mAh 2S 50C lipos that I had purchased for my LC Racing EMB-T that fit and are perfectly up to task to power the Tenshock motor. These are great batteries, but a bit on the expensive side. I’m in the process of finding a different mounting methodology that is secure but more convenient. Stay tuned for updates in this area.

Final thoughts on the LC12B1
This is by far my favorite car in my stable at the moment. I am absolutely thrilled how this build turned-out. I think with the details I have shared from my perspective on this car, it should be clear why I feel this is the undisputed King of the 1/12 4WD race buggy category. It’s too bad there aren’t more manufacturers dipping their toes into this arena as I would love to see more competition in the market. Until then, I’m going to go and enjoy ripping this little buggy and tinkering with the suspension, gearing and drivetrain to get it dialed into my preferences for handling and driving dynamics.

Comparison to the WL Toys 124019
​Bonus content of a side-by-side comparison between the LC12B1 and a WLToys 124019 that I overhauled and customized for my neighbor that is still running the stocked brushed electronics. There can’t be two bigger contrast between the King of the Track monster and the King of the Smiles per Dollar category. The photos also really highlight how closely WLToys cloned this platform in terms of dimensions. However, what is not so obvious in photos is the fit and finish, tolerances and materials that you can only feel with the product in your hands. The 124019 is running the same Phat Bodies Hammer shell, LC EMB-T Wing, LC EMB-MT Bumper and a set of LC EMB-SC Wheels.

I just built mine last week but haven’t run it yet, contemplating electronics choices. So excited about it tho. Love the extras you used here and the look is spot on. Great work.

I’m going to go full on road rally car with mine using the phat bodies zero body. I just need some serious paint practice before I attempt it. Mixing vinyl wrap in like you have will surely help, thanks for the illustration.

It’s clearly a better car than the WLToys versions of which I also have a few, but I’m surprised how well they did in copying lc racing and selling for such a great price. My brushless conversions are a joy to run and for a car that costs 2-3 times more the lc racing offering is gonna have to handle like a dream to justify the cost 😀

Thanks and yes, Geoffrey did a great job on this article. Mine has arrived and I'll be building it soon. I drive my WL toys cars more than my LC cars too because I have customised more to specific purposes. That may change with the 12b1 though!

Hi, great article as always!
I have a question regarding the shock springs.
How much stiffer are they comparing to the wltoys ones?
I have the feeling, upgrading a speedrun car with the stiffer lc racing springs has its benefits, at least in the rear.

And what I’m curious about is the amount of extra fun come with the money for such a kit, when you have already fiddled about with the wltoys. I mean, it’s all very familiar and not very challenging?

Thanks!!

The stock springs on LC Racing are quite a bit stiffer overall compared to the stock WLToys. Even the 1.1mm springs have quite a bit more resistance. For a speedrun car, I wouldn't go stiffer than 1.2mm as it would negatively impact handling if there is no give in the suspension when it hits a small bump, it would basically deflect the wheel.

I would say building a kit wasn't meant to be a big challenge in any way. I enjoyed building the kit because it was well engineered and I could take my time to decide on how I wanted to tune/modify the car without the need to disassemble and struggle with crazy glued screws. The fun comes from having an intended purpose for a build in mind, piecing it together and being able to drive and test end product and further refining it with tweaks and adjustments to get it dialed in to how you want it.

I totally agree with your conclusions.

It’s really a pinnacle version of the WLToys you may be used too and if you are invested in that platform and have money to burn it makes sense to treat yourself to a LC Racing has offering. I really enjoyed putting mine together and you really notice the quality. The screws in particular are SO good compared to the WLToys ones.

Nice little write up you got there. We race these and they are very fun cars. Few tips:

- The rear stock plastic carriers has one side that has less toe than the other, the aluminum option part does have this problem
- We run slippers locked down on carpet as the pads would glaze over too quickly
- slightly grease the diff cups for more life
- the harder LC12B1 a-arms and there hingepin inserts are both the same material and have like no give, so you will end up bending hingepins on a hard enough hit. Get the regular rubberish hingepin inserts and use those, has alittle more give and can save you some hingepins on hits
- If you can find it, There are two sensored motor options out there, you just have to make sure you have an ESC that can reverse direction. the Leopard motor is one powerful beast, if you can find it.

Thanks for the input!
- I will likely tighten the slipper the next time I take the car apart based on this feedback. I can hear it whistle when hitting the throttle hard, so will experiment with that.
- I'll consider getting a set of the regular hinge pin inserts
- I'm not really racing the car at this point, but I am aware of the Leopard motors and have noticed they are quite rare since being discontinued. I'm pretty happy with the Tenshock at the moment, but may look for something if I decide to do some more serious racing.

This is great info. But can you elaborate slightly, I’m new to RC still.


The rear toe issue, to solve you recommend the aluminium option?

Does the slipper clutch need tightening in all situations? I run mostly on asphalt. What exactly is the effect of having it looser.

Would you grease the diff cups outside of a carpet track situation? I’m thinking it may attract debris in more off road terrain?

Awesome, I ordered the same kit after I have read your build. Got it built last few weeks and I noticed the buggy is making squeaking sound as I turn and go forward at the same time.

Nice! Geoffrey is out enjoying his and I'm yet to build mine - at least parts have arrived. check nothing is fouling around the hub area and that the driveshafts are all aligned correctly, you shouldn't have squeaking!

alright, thanks for the advice, willing be checking on the hub area and the front driveshafts. And if I have been thinking to change the stock spur gear to Hot Racing 48p 58t steel spur as I keep stripping the stock spur gear. Hoping someone could advice before I proceed to order it. It is still a great RC car regardless of the minor issues.

I have been using a losi mini 8ight for 5 years, but the lack of parts and their price made me consider buying a lc12. My project is mainly geared towards speed runs and I miss a longer chassis to improve stability. In my mini 8ight I can use lipo 3s 106mm long and I wonder if they would fit the lc12. Another doubt is about the spur gear because I didn't find any option with less teeth than the original for this car.

Thanks for the great write up. I purchased a 12b1 over a year ago, but life has kept it on the back burner and I'm still putting the finishing touches on the body and decide what motor I want to run in the long term. I'd love to hear how the tenshock motor is working out! Also, I noticed there's about .5 mm clearance between the motor and chassis. I'd like to apply another trick I learned on this site and heatsink the motor to the chassis with heatsink paste. Is that gap too big for this trick? Alternately, could a 29mm can (seem to be primarily used for boats) be fitted to close the gap?

Just re read the guide and noticed the tenshock IS a 29 mm can. Feeling a bit sheepish!... Any idea how that 1401 motor compares to the surpass 2938 or 2948 motors?

I don't have any experience with the 29xx Surpass motors. I have only used the 2845 Surpass motors, which are great for the price. I can say the Tenshock power delivery is much smoother in comparison. The magnetics in that motor are also super strong. Really great motors for this scale.

I am just about to build mine + already have the RTR Truggy with 3 x 94mm long 1800mah batteries.

Before I copy most of your set up, is there anything you were not happy with & did you find a good solution to the battery being hard to fit quickly and safely?

I also still have to order a motor and ESC - I might go with the ones from the LC racing site until I find a sensored one... or I could put in a cheapo that came out of a v1 WL toys 124017 since its hanging on my wall with an ESC and has already been de-glued from its mount.

I also need to fins somewhere to race this in NZ :)

Overall, very happy with the build. If I were to do things differently today, I would consider looking at the newer, larger Tenshock x1401L that was released not long ago for something different as it is supposed to be better suited for the longer chassis cars. My fix for the battery tray was to have one 3D printed. There are a few community members who have released files on Thingiverse that address the way the battery is held by replacing it with a more sold tie down at an angle to keep it away from the side tray screws.

I already ordered the motor you have, but 2 x ESC orders were cancelled so still no ESC yet (unless I use one I have from a 124017)

I also got the batan 135 MG servo for my EMB-t truggy (actually got 2) and it's not as good as I had hoped.

The steering slop and servo is the one area of the LC racing cars I am not 100% happy with. Did you figure out what the best servo upgrade available is (I'd be happy paying $150 bucks for a great steering servo that fitted without too much cutting, but can't find anything and I don't want to buy one that is too big).

Thanks again

PS I used the "tophats" I took off the WL toys car when putting bearings in it to take some slop out the LC steering (smaller holes for bolts).

Futaba BLS671SV is the best servo for this car

Cheers, I'm going to get one of those servos.... once I get my lc12 to oversteer a bit less on slippy surface (the same set up on my Emb truggy understeers).

Next step is thicker rear diff oil (same thickness as front).
