Hi all. Trying to tune in my APM 2.0 with V3 firmware for Alt Hold for a customer on my custom, folding, 400-size quadcopter. She oscillates (vertically), then gently starts dropping until it lands.
I've tried some of the tuning tips, and reduced the oscillations, but she still drops. Any hints folks?

Log a flight and compare GPS relative Alt to BaroAlt.
It's also possible that the prop-wash is affecting your barometer since it's so small and the props are so close to and above your APM.
