Motors 3 & 6 bounce up and down hex x (Log now attached)

[Jdmagoo]

My Hexa is orientated in the Hexa X format and my left and right motors after a period of time start to vibrate causing the arms to move up and down, there is also a whistle type sound (i think are coming from the same ESC's) almost sounds like birds chirping.

Anyway, what would be causing this, my PIDS, ESC32 settings or perhaps EMI from the signal wires? I would attach a log but for some reason the AQ stopped logging after a minute.

Will try another flight tomorrow and hopefully the log will work then

Cheers

Please see attached of a quick flight. (I've trimmed it down so i can upload)

So the problem exists straight away on take and during the hover, it wasnt until i banked the aircraft left and right before the jittering stopped and the whistling sound stopped.

Im not sure if its a PIDS setting or ESC32 not starting up correctly. I have had problems in the past where a random motor wont start until i disarm rearm.

The PIDS at the moment are default as of R254

Just to add, i noticed before bringing the motors to full power just before takeoff that they didnt sound right, hard to explain but sounded like they were jerky. I suspect the problem is a combination of not having the correct ESC32 settings and having TILT RATE D to high.

thanks for looking

Hi James
Something is wrong with your roll axis. Hard to tell what. Maybe you can provide a vid?

Hi James

Good to hear you found the bug.
Did you adjust CTRL_FACT_THRO when adding the second battery?

Cheers
