Do you have any pics of your setup and maybe a video? Have you checked the orientation of the flight controller? Aka is it turned 90 degrees or backwards? Also some motor, ECS, and prop info would be nice to help.

Also what are your pid settings set at for pitch/roll and yaw?

Try going up to 12-12.5 on the pitch and roll and about 4-4.5 on the yaw.

Alao do you have any anti vibration in use?

on the stabalize roll and pitch?

You might want to think about it eventually to help. Not needed in every case but would only help the accelerometers by reducing vibrations.

on the stabalize roll and pitch?

Yes for both. You might want to work your way to 12.5 and 4.5 but you will find most users end up in that area. Try 6, then 9 and then 12 and if it gets better each time keep going. Or you can go straight to 12 and then back off if you see different behaviors.

did you try and increase the settings from above?

you can upload to Youtube and then link to that if you want to share a video.

Nice job attaching videos. you have some odd vibrations.
1. Have you tried different props?
2. You can try but don't do it long but have you tried no props to see if its the motors?
3. losen your FC board screws a bit to allow some wiggle room or add rubber washer to remove some vibrations.

Anyone else have any suggestions?

 

[mr9802]

one other thing? do you have your motors wired up correctly? it looks like it fighting itself a bit.
