Good Morning,

Having strange A3 pro problems, on my S900, toilet bowls on take off, then (sometimes) settles off, drifts horribly in ATTI with no wind, and getting nasty vibrations some times, I thought this was due to battery tray's but that doesn't make any sense as they all flew fine with the A2 before I upgraded to a more 'robust' system !

Any suggestions delightfully received, at the moment I have lost confidence in the platform, and that's not a good thing !

Cheers all.

Just to clarify, do all the LEDs on the A3 GPS pucks appear normal? Have you double checked your X,Y and Z values? Is this happening right out of the box (A3 wise) or did you notice this after a firmware update? What firmware/Assistant 2 software are you currently running? Could you happen to provide a list of your whole set up?
