Hi folks,
I have problem with drifting of my hexa during YAW rotation.
Strange is that when I'm rolling YAW left - hexa drifting left 4-5 meters, and in opposite, when rolling right hexa drifting right more or less same distance...
This is my second setup, now it's based on Tarot 6800pro, previous one (F550 - all equipment is the same) going perfect.

Of course all calibrations (compass and IMU) and positioning of GPS compare to CG was done.

Any ideas how to solve the problem ?

best regards, jacek

The Tarot motor mounts are moveable on the CF tube arms (see this listed as a virtue).
Since you say that you've checked everything else, be sure none of your motor/prop assemblies are out of the parallel rotor plane...

Also, since the only thing you changed is the frame, and the DJI equipment worked well on the DJI frame...
You can see where that points...
Check the Tarot 680 frame over carefully for slack/movement in the arms, vibration, etc.
You might need to get some advice from a Tarot forum...

have you solved this? I have the same problem with a Wookong and I think my IMU needs recalibrating or replacing.
