The drone seems fine anywhere from 0 to about 70 meters before trouble starts to occur where as I go higher up the gimbal shall start to move diagonally. I have re calabrated the gimbal, done all the other recalabrations too.
Only had the drone over a month but don't know if i can even send it in as I thought i'd have more time to buy refresh.

Any ideas would be greatly appcreciated

Can you post a screen recording of the issue?
