Sk450 Wobbling Problem
I have a sk450 quadcopter, but since I crashed it, I have many problems.
When I crashed the copter, I thought that I'll try the Graupner eprops
When I started the copter, I felt a very strong wobbling, when I put the throttle in the upper area.
I held the copter in the middle and opened the throttle.
I noticed, that the frame-arms warped when the throttle was high.
This caused a very strong wobbling of the whole arm.
I have the NTM Propdrive 2628 1000kv motors, the kk2.1 and Afro 30amp escs.
Have you got any idea how to fix this?
I you want, I can shoot a video of it.
Thanks and best wishes,
Ps: Please excuse my english mistakes :P

You may have bent one or more of the motor shafts when you crashed. That would create vibration.
The motors since the crash and the new props may be out of balance.
You may have hairline crack(s) on the warping frame arms, or where those arms attach to the main frame, the main frame, or where the motors attach to the frame arms.

thanks for your reply.
When I hold the arms at the little landing spacers, nothing vibrated.
When I held it in the middle, it vibrated like hell.
I think too, that the hairline cracks are the reason.

kk2.15 board is one of the hardest to set it right. if the gain is too high, wobble is there. you can adjust lower. i have one kk2.15 board.
