Copter drifts to side during yaw

I’m not sure if this is a hardware or software issue…
When I yaw around, the copter drifts to the side by about a meter.
The copter is pretty well balanced. I ran a log analysis and the motor balance is “good”.
Does anyone know what would cause this?

I was in stabilize mode. Quad. 3.4.6


Without a .bin log file to analyse we could only guess.
You need to provide a log file when asking these questions.

I googled, and saw this was an issue w/ DJI and toy copters and everything, so figured it was a mechanical issue someone w/ experience would know the answer to, hence no log…

BUT, I will get a log next time I’m out and we’ll go from there.
