RE: How to troubleshoot an electric problem?
One more suggestion is to turn your TX on first then plug in your RX/ESC battery. On shut down, RX first THEN TX.
Just the opposite of what you would do with glows. With glows, RX first THEN TX, then on shut down RX first THEN TX.
With mine, I find that if I don't follow that, sometimes the ESC goes into fail-safe and will not start. I have to shut down then go RX first then TX. Most TX's have "TX-HI" to prevent it from acutally coming on until the throttle is actually at idle so the prop should not turn.
Good luck.
