Out of curiosity...
I built a helicopter with 900mm blades. The rotor speed is around 1150 RPM. My problem is I am having a hard time getting the helicopter to hover correctly in Loiter Mode.
I was thinking maybe due to the slow head speed that the 90 degree phasing doesn't work so well with a helicopter turning at a slower head speeds. Meaning that it might not be 90 degree phasing it could be lets say 80 degrees? Is there a way to tune this within Mission Planner?

Found out by increasing my head speed to 1200 RPM's and increasing Pitch_FF and Roll_FF my loiter works a lot better. The helicopter is no longer out of control feeling.
Sean you might want to upgrade when this comes out: http://diydrones.com/profiles/blogs/apm-2-6-gps-with-compass
Hey Sean, I'll see if I can look at your details here in a bit. What is the heli? 900mm blades are big!
Is the problem with Stabilize, or just Loiter?
there is a parameter for that although I forget exactly what it's called. PHANG maybe? I actually think that is probably not the issue though. you're using a ublox GPS? your compass heading is OK? there's a few possible causes but we should probably see a video and/or log files
