The WL Toys 144001 is a great car for the money and pretty durable but certainly not the toughest thing out - for my money that goes to the SG 1601 / HBX 16889 (long term review here). I have however found an tested a few direct bolt on parts that you can install in about 20 minutes to make this way more resilient to crashes than stock
By now I've made a number of brushless upgrades to the WL Toys 144001 which I've documented, each with a different objective in mind. All of these offer an improvement over stock which, depending on option offer an improvement of speed, acceleration, weight, balance and efficiency over stock. The objective of this brushless upgrade is simple - the cheapest brushless setup worth having for bashing
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.
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.
The WL Toys 144001 is a very fast little 1/14 scale RC car thanks to it's massive 550 brushless motor that powers it with some rather tall gearing. The downside to this is the heat that it generates. Over time this heat can damage electronics and cause a decrease in performance and indeed motor failure. This is a quick and dirty guide to significantly improve motor cooling for less than $2 which should only take 5-10 minutes to do with simple tools.
I love the WL Toys 144001 1/14 scale RC Buggy and have written a lot of articles on tuning and upgrading it here. It is inexpensive and runs well stock or is easily upgraded to brushless power which offers better speed and acceleration as well as battery life. But how does it compare against the car on which is was based, the LC racing EMB series on which the 144001 was (let's face it) copied from?
So surely you know by now that the 144001 is a budget copy of the LC racing EMB-1 but with a bigger brushless 550 motor and integrated ESC/receiver and no slipper clutch. This means that WL Toys have been able to grab a big slice of the popular RC car market at a price point of $70-80 for the 144001 vs $200ish for the LC racing equivalent. But this is clearly not a fair comparison so what if you take the brushless upgraded 144001 with a raft of replacement parts, tally up the cost and then compare? Would you still buy the 144001 to upgrade or would you just got straight for the LC racing? I'll break this down by price and performance in order to give you the clearest information to make this decision for yourself and my opinion I what I would (and did) do.
The WL Toys 144001 is a small 1/14 scale 4wd buggy with a massively oversized brushed motor that can reach well over 30mph. When this massive brushed motor is replaced with a massive brushless motor the top speed can become over triple that with the right setup. The below guide goes into detail the build components I used for such a build, the build process and setup to optimise handling.
By now you've probably seen some wild speed run builds based on the WL toys 144001 of up to and over 100mph. At the top end of the scale these are highly customised with expensive race-oriented gear and outboard twin-battery power supply. The objective of my build was stealth: to retain the stock look, making everything fit (somewhat tightly) under the stock bodyshell and be bolt-on without the need for machining or fabrication i.e. as simple to replicate as possible. For this reason I have specifically chosen to run my car with stock gearing on 2-3s only. To that end here are the parts I chose and why,
Parts used for build:
I've separated this into power system for the key components...
For those that upgrade to a much larger ESC in the WL Toys 144001 these is often an issue where the fan and or heatsink of a larger ESC fouls against the shell in the stock position. If you don't want to change the shell and don't want to jack it up I have a solution for you.
Although I recommend the 2838 brushless motor/30a ESC upgrade in this article for the 144001 for general bashing, speed runs require much larger ESC that typically have fans installed. In this particular build I used an 80A Flycolour lightning ESC that, although compact, fouls against the ceiling of the 144001 shell. Because this build is for road only I didn't mind a cutout in the shell but wanted it to be tidy and discreet. The easiest way I found to do this is as follows.

I've now built up quite a library of articles for the WL Toys 144001 (and 124019 / 124018) and thought I would use this page to share them. As of 25 May 2021 I've finally done a bit of an overhaul to make sure all articles are included and have added some new categories plus reviews. Enjoy!
I've now completed a number of articles that have improved the handling, power and efficiency of the WL Toys 144001 and 124018 and 124019 which can be found here: All my WL Toys 144001 /124018 / 124019 upgrade articles. The next item I am addressing is the tyres. The stock wheels and tyres (like the rest of the car) are modelled closely on the LR Racing EMB-1h micro pins which are designed for carpet and hard packed dirt racing. Outside of these grip isn't great, and when you take into account the the rubber is firmer on the 144001 tyres then you are left with a tyre that is not really suited well for bashing off-road. In this article I'll explore some better bashing alternatives that shouldn't compromise the rest of the car
Stock wheels and tyres
Stock tyres have an outside diameter of 72mm which is the same front and rear (it needs to be on a 4wd). Widths are staggered meaning they are slightly wider at the rear - 30mm compared to the front - 26mm. Again typical for a buggy because on acceleration weight transfers to the rear and the extra width provides more grip. Drive on the wheels is provided by a 12mm hex drive which is something of an industry standard on cars around this size
The problem is that a combination of the design and compound of the tyre mean that they don't grip well on the majority of surfaces we run (off road bashing and tarmac). Since the 12mm hex drive is common there are a lot of wheels that physically fit but not a lot that work well because of the uncommon diameter. On to the theory:
Lithium Polymer (Lipo) battery technology has been perhaps the best leap of technology in the RC world. The relatively high energy density and absurdly high continuous current capability has meant that quadcopters have become a viable hobby and electric RC cars can now outperform their Nitro cousins without most of the fuss.
Voltage as measured in volts (v)
A single lipo cells has a maximum charge voltage of 4.2v which is usually reported as 3.7v for real-world purposes. Voltage can be increased by connecting these cells in series (s for series) and is reported as 1s (1 cell in series), 2s (2 cells in series) 3s (3 cells in series and so on). Voltage is additive when cells are placed in series i.e. 1s = 3.7v, 2s = 7.4v, 3s = 11.1v and so on.
Capacity as measured in milli Amp hours (mAh)
Lipo cells can vary in capacity, these are measured in mah and signify the amount of 'fuel' the lipo battery can output before it is depleted. All else being equal the larger the capacity they larger the physical size and mass (weight).
C - Rating
Where voltage and capacity are simple physical parameters, C-rating is slightly more complex. It is closely tied to capacity and has no relationship to voltage. In short the C rating signifies the maximum continuous output that the battery can maintain. Strictly speaking the C value multiplied by the capacity is the maximum continuous current output which we measure in Amps. The best way to describe this is to give examples:
