BEC and separate rcvr battery at the same time?
My ESC has a built in BEC, but I want to be able to power the radio without connecting the motor battery. Is it OK to power the receiver with a separate battery while the throttle cable from the ESC is also plugged in? When I tried that the ESC issued its startup beeps and the motor tried to run if I moved the throttle stick. That doesn't seem right, but I don't know.The receiver and servos did work, though.

Hi Jack. Try disconcerting the red wire from the ESC plug that goes into the receiver. I had to do that when I hooked up a setup like you are trying.That way the BEC in the ESC is not trying to power the receiver while you are useing a separate power supply for the receiver.

Dunno. I asked Castle and they said to not do that.
