Not sure if you have already tried it but, sometimes the throttle needs to be reversed on the remote before the ESC can be programmed. I have a Futaba 3PK and a MMM and I had to. Good luck! Awesome build!
hmmm... the only other radio i have is the TQ that comes with the stock e-maxx. Im not to sure witht this one. I remember having the exact same problem, the steering servo working, but the motor not working when my EVX-1 packed it in. Thats why im a bit suspicious of the ESC. Hopefully SV6000 knows something i dont know
