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...
....and the boring but necessary parts
...And the tools I recommend if you don't already have them.
Please see images below with description to take you through the build process. There is no cutting in this process.
When the car is running at this kind of speed you want to be very sure that all of the settings are dialled in straight and all of the stock items are performing at their peak. In order to do this, please follow the below articles to set up the following:
Adjust the suspension collars to that drive shafts are parallel with the ground front and rear for maximum efficiency. Once this is set, adjust the droop crews (if used) so that they allow the suspension the wheels to drop another 5mm or so when lifted so you are not sitting on the droop screws as this can mess with suspension feel.
Unfortunately this is where the journey for this car ended. In September 2020 all of my RC cars were stolen from my garage so I sadly never got a run on this car, even a quick shakedown. My primary goal was to hit around 60mph or 100kph on 2s and perhaps a little faster on 3s but it was more about the build than the top speed as I never had the desire (or deep pockets) to compete with the guys out of Aussie (The RC Master and Sel Gules from the 144001 Facebook group in particular).
I will say that speed runs are hugely specific and although they look rewarding I feel I'm more about the bashing (on and off-road) which is why when the insurance money comes through I will likely repeat my brushless build with the smaller 2838 brushless combo as I wrote about in this article. Thanks for reading, I hope if nothing else this gives you some ideas for your own build.
