After a few successful flight tests with my quad. I’ve not been able to fly again, I think its a battery issue cause one of my battery cells got bad, its an old battery(3S 3600mAh 11v).
But of recent, I discovered that my servo outputs doesn’t all go up when throttle is increased, One particular servo output doesn’t get pass about 1200, it remains at the same position despite continues increase in throttle. A second servo output doesn’t get past about 1650, the remaining two servo outputs are increasing and decreasing fine with change in throttle value.
With pitch, yaw, roll and flight mode at stabilise, shouldn’t all servo outputs move up or down equally as throttle is moved?
Please, what could be the issue?
My ESC calibration and Radio seems okay.
