The WL Toys 144002 is a fantastic handling 1/14 scale monster truck that I reviewed here in full. It is really let down by the powertrain though - although it has a large brushed motor, the gearing is way to tall with the big wheels and suffers with terrible acceleration, poor torque and poor battery life, none of which is a good match for a monster truck and offroad conditions. In this article I will present an easy to install brushless upgrade which is inexpensive and performs great with double the battery life Let's get straight into it: Brushless motors are much more powerful than their brushed counterparts and so simply choosing one with the same dimensions as the stock motor is a poor choice. It will remain heavy and you still have not solved the issue of tall gearing since you are stuck with these same pinion gear on these large motors. Even with a low KV option this will still make for poor acceleration but will now add cogging into the equation similar to what we saw on the Eachine EAT14 (reviewed here) Below are the components I've chosen for this setup, the whys and alternative options. Components Brushless Motor
Brushless ESC
3-wire Servo
Radio Gear
Pinion Gear
The last part you will need is a pair of countersunk M2.5 x 8mm screws like these ones. These will fit the new smaller motor to the stock motor mount. Installation Guide Installation is very easy, I've taken lots of pics to guide you through the process below.
Performance Review
The only downside I found from this upgrade was that this particular ESC I chose has a bit of a delay from throttle input to motor acceleration. Decreasing the throttle dead zone could using the programming card may help a little but will not be a complete fix. I can confirm that this is the ESC because swapping the radio to a DUMBORC set made no difference. This is consistent to what I found in my WL Toys 144010 review although not as pronounced with this car due to the shorter gearing. For this reason I'd recommend the Surpass KK 35a esc or the hobbywing if you had more to spend, Recommendations I can't recommend this upgrade enough if you have this car, It really does fulfil the ultimate potential with big improvements over practically every characterstic of this car. Being able to reuse the radio through use of the 124017 reciever makes this upgrade quite cost effective and as such is one I strongly recommend for the WL Toys 144002. The little 3600kv motor is a great match for the 15t pinion and large wheels on the 144002 with great torque for offroad bashing without the issue of overheating.
