This in on my new Dynam C188. I thought it was the RX so started this thread.
I don't get why the servo tester will work but two different RX won't...
Spektrum - AR620
TX is an old DX7. ESC throws some type of alarm when I power up. Bind RX with TX via slave battery. Everything (servos) works fine. Power down, plug in ESC to RX, power up... repeated BEEP-BEEP, etc, etc. Control surfaces work. No throttle. Hook up servo tester, power up, ESC/motor work...
