  6. Take the pinion gear and slide it on to the pinion shaft and tighten the set screw.
  7. Now slide the motor slightly forward or backward to set the gear mesh. (make sure the teeth fit between the teeth of the spur gear. I use a piece of paper folded between the two gears and tighten down the motor)
  8. Once gear mesh is set and the motor is tightened, install gear cover with the (2) mounting screws.traxxas brushless motor wires
  9. Run the motor wires back through the shock tower and connect them into the ESC. Make sure the correct wires are connected. Color white, yellow, and blue should connect to the same color on ESC(blue to blue, White to white, yellow to yellow) or A, B, C
  10. If they are lettered, Then usually are as follows: A to blue, B to yellow and C to white.

  1. This brushless conversion was pretty easy to do. After reading this article, I converted my slash to brushless. Your guide was easy to understand and follow, thank you. The question I have is, if you wanted to go with a different motor other than traxxas, would it need programming?


    1. Hello Victor,
      If you wanted to go with something else like castle, you would need motor and esc. In that case yes, it would need programming. Really any motor/esc combo other than a factory system will need to be programmed.
