With number 5, Start by resetting your sensitivities to 0%. Do a test flight then make small adjustments as required.
@Jummivana - it might be worth flagging this post to zendesk with a kind of “check you’ve tried these quick fixes before raising a ticket” message - or perhaps creating a “guide to reesolving control issues” in the zendesk FAQ a bit like the camera guide
Just a thought. I’ve lost count of the number of posts on here with control issues easily solved by one of these suggestions (appreciate the metric one is hopefully going to get fixed soon, but the others are definitely “pilot errors” that are easy to make, but easy to fix too).
