Traxxas TRX-4M BRUSHLESS System

Very nice product.really easy to install has good power for the size motor.everything’s plug and play super simple. also to add on the motor fits onto stock transmission.

can go very slow and very fast but I recommend putting the low range gears in the transmission because the torque is quite low with regular gears fast install and fit perfectly.

Pros: easy fit and plug and play, you keep the Traxxas radio, insanely slow crawling with the ability to keep consistent speed over obstacles, very quiet, and it is about 2.5X-3X faster than the original brushed motor. Cons: Super jittery at some points, a little more expensive than other competitors, motor heats up super quick and gets very hot, motor hits a point when at 1/4-1/3 throttle that makes it lose all torque and will roll backwards or stop moving all together. I sent the original one back to Traxxas after contacting their customer service department and explaining the roll back issue I was having. They sent me a new system all together but I still had the exact same problem. I went from standard gearing to low range to make the problem less dramatic. I contacted customer support once more just to let them know I was having the same issues as before. This time they said that there’s a point where the motor/speed controller go from low speed to high speed and that’s when it loses torque. When past or before that point, it’s fine and smooth. I might try to retrofit a motor from another company to see if that fixes the issue, but I have low expectations.

Works great awsome easy install be patient and careful

Nice ESC and motor. I ran into an installation problem. Two holes on the motor spacer were not threaded. I ended buying an M2 tap and corrected the error rather than go through the return process.
