Help - Motors won't fully spin. Quad will arm, one motor fully responds, other 3 flutter but SOMETIMES spin up with much plugging in, unplugging and general coaxing. Then, responding motors go back to flutter after disarm or throttle to zero.
emax 1806 & 12a Simon k ESCs,
HKPilot Mega Micro Flight Controller
Spektrum DX 8
Lemon rx pwm
What I've done:
APM setup multiple times (accel, mag, tx, etc.)
Group esc calibrate, haven't tried one by one yet.
Suspect esc switched to motor that spins.
Different flight controller
Reprogrammed ESCs with what emax manual suggests.
No joy on all the above. 3 motors oscillate and get warm. Can't get quad anywhere near flying state.
Thanks, Eric Walters
