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.

  • I have two of these systems. Both run very well for the money. Very powerful for no more than they cost.

How can i get this to calibrate? When i hold set it just stays steady blue.

  • This one is sometimes glictchy and takes a few tries before responding. The blue cheaper combo is better. Use the Black Programming Card. It seems setting 1 and 3 work best. I wanted setting 2, but never worked right for me.
