Will this work for my traxxas slash

  • Yes this will work in your Traxxas Slash both 2WD or 4WD, and it would be a significant upgrade over the stock Brushed Titan 12T, but a downgrade from the Velineon system. I hope this helps

I bought this and the programmer and it won't go up for anything to program. How can I get it to program?

  • The programming card I bought with mine didn't work. I watched a youtube video on how to program it using the transmitter and set button. Its a good little combo but the instructions are crap and the cards don't work with it.

Would this be a good motor swap in my redcat volcano?

  • Not sure about volcano but works really well with Traxxas Stampede. Make sure you run a lipo.
