I got my hexa flying quite reliable in both Stabilized and Acro mode as well. However there is a little issue which I am not sure where to put and how to solve.
I fly in Stabilized mode, I trim the hexa out and it flies stable barely wondering around. When I switch to Acro mode it leans a bit backwards and it starts coming toward me. I trim it out, it flies again stable and again barely wondering - but if I switch back to Stabilized mode it will start going away from me and I have to trim it again.
The APM is 2.5+ and i has the latest 2.9.1b.
I calibrated the accelerometers 2-3 times also did a level resetting by holding the throttle/rudder to disam position for 15 seconds - and it is still doing that.
Is there anything I am missing?
