Did you connect the bec to the esc power leads? If you're still stumped do you have a rx pack you cann throw in and try that instead of the BEC?
Yep, maybe your CCBEC is toasted. Like said Matthew, try with a reciever pack on the BATT slot. And don't forget to remove the red wire on the ESC cable.
I got a new bec and did the same thing and no steering and throttle. I hot wired the red w/red wire on the esc along with black and pulled out the red wire in the channel 2 and put the bec in channel batt. what do I do with the on/off switch from the ESC? do I have to hot wire this as well?
