Hi after setting up my H-Quad with the APM 2.5 loaded with 2.9.1b (final), I have a problem with the quad wants to free fall (about 6-12 inch) when switching from Stabilize mode to Loiter mode, How can i stop this from happening? or reduce the affect ??
What setting would i need to change??
Any help welcome

When you hover in STAB mode, is your throttle stick above half-way?
If that's the case, when you switch to LOITER it assumes it will need 50% throttle, so it falls for a sec until it compensates. You can fix it by setting THR_MID higher (e.g 500 is 50%, 600 is 60%), either by guessing relative to your throttle stick or looking in the logs to see what THR_IN is when you're hovering.
Strange, I was using Position hold, then activated alt-hold (loiter= position hold + alt hold), when immediately my hex started to go down.
Not free fall, but very fast.
