I don't usually see this unless the voltage drops a decent amount. What size batteries? Does the voltage show on your screen so you can slam the sticks around and see if the voltage drops much?

Oh ok. Sounds fine. Knowing the plane was off would of helped in the beginning. Happy flying

So the motor in a servo is basically acts as a generator when the servo is manually moved when power is off. If you want to experiment with it, just take a volt meter and a electric motor you have on hand and try it. When you spin the motor by hand you will see a corresponding voltage readout on your voltmeter.

Correct, you can do this with almost any servo. We used to take a coreless digital and remove the end point stops, then hook a hand crank to the servo output and generate power by hand cranking.

Not much difference between an electric motor and a generator
For many years to reduce cost and weight Golf cart companies used the generator as the engine starter
