Pixhawk Tuning on a Mini X Frame (Issue)

Hello,

I have built a mini X-Quad blow are the specs.

Air frame type - Quad

Size - 285mm

Frame Material - Carbon Fiber

ESC's - ZTW Spider 18a NoBec

Motor - SunnySky 2207 / 2100Kv

Prop - Hq6045 Tri Glass/Nyon

PDB - PDB with volt & current sensor 5 & 12volt regulators

Telemetry - Yes

Current PID's attached.

I have tried to lower PIDs as low as possible and am still having really bad roll oscillations. I also was getting Yaw oscillations and after lower P & I as low as they would go I add some D and that seems to help. 

Any help would be great 

Thanks!

  • Got it. I had to increase the Gyro Filter it was set to 15Hz I bumped it to 40Hz and it flies perfect.
