Hi!
I know that the topic is very popular, I read all YAW treads here, but I still can't solve my problem.

The issue is that when I turn stik right, drone rotates right sharply and after centering the stik it turns left a little. But when I turn left, it smoothly turns and after centering the stik it still turns left for a while.
I did calibration of ESCs, gps\compass, reseted naza to default sets, disconnect gps\compass module, but nothing helped.



Frame QAV 400, t-motor 2212-13, esc Maytech 25A-OPTO 400Hz Simon K, props APC 8x3.8, Turnigy 9xr



I will be glad to hear any thoughts.
Thank you!

I'd also suggest to adjust the GAINS, it seems like the drone has a relative lower BASIC GAIN with relative higher ATTI GAINS

Before setting NAZA to default I was trying to solve the problem by changing GAINs. For the moment of now gains are basic.
I'll raise basic gain and reduce the att gain, as you said. Hope it will help. Thanks.

It sounds like a remote triming. Try trimming the remote and aldo check the calibration in the assistant.

This symptom we often se when motors are unevenly mounted.
However i see you use a qav frame, and i know thes have solid arms wich are hard to get uneven, unless youve had a crash.
The 400 uses compositt arms right? g10 or something along thoose lines.

Yes, there was a crush, but i can see no curved details in the frame.. Maybe I should try advanced IMU calibration?
