Post crash rebuild - problem

[TheFlyingSquid]

Unfortunately crashed into a tree and cracked one of the arms on the Vision when it fell about 30 feet. Have obtained a new shell and put all the components into it. Nothing obvious on the boards or ESCs. The motors all spin easily. Fired it up this morning and it seems to work but on hover it drifts and suddenly jerks laterally and does not seen to be able to easily hold its elevation. It gets home lock and 8 satellites. On assistant everything checks out OK with GPS and the IMU. Where should I be looking to fix these problems?

Thanks for your suggestions

Alex

Are you flying with factory props? Changing out after a crash to aftermarket props (even one) can make a mess of the quads stability.

yes new factory props

Check GPS Antenna for crack?

None that I could see - will get magnifying glass out and have a closer look

Did an advanced calibration Seems to have fixed the problem.
