Hey,

I recently installed my GT replacing an RS and noticed that during initialization, not all 3 servos jump in sync. It seems that mostly the elevator servo moves and the other two only slightly. Everything seems to be working ok after init, but wanted to check before the next flight. I posted a video below.

That is pretty weird. Only the elevator servo makes a robust jump during initialization, but the servos seem to respond appropriately AFTER initialization. I hope to learn the answer soon.

go to diagnostics tab and check if there is a log from last flight (or last test). if there is some important event, the different init servo jump is an indicator for a stored log from last flight.

Thanks, that was it. I had a low voltage event from the bench test.

Interesting thing is that the issue I saw was different from the Troubleshooting section of the manual that states:
Elevator servo is not moving when initialization is finished

The behavior is without any change for years.
So it only mean there is saved log from previous flight with some important event.
