hi, I don’t think it’s performance related

But when my mp2 is turned off the gimble has a lean to the right (mp2 facing you)..

It never use to.. use to keep dead middle when turned off ..

Is this a sign of getting warned out.. or nothing to worry about

Hi there, thank you for reaching out and we're sorry to hear about the trouble. With regards to that, this would be normal since when the Aircraft is turn off the Gimbal can move freely and the Gimbal itself doesn't have the power to stabilize. Thank you for your consideration.
