I've trashed my landing gear so far. I just installed the sonar, and was trying to get ALT_HOLD or LOITER to work nicely with it but it didn't seem to climb when the wind made it drift into a hillside on ALT_HOLD.

Now I'm getting assymetric lift, the tail comes off the ground first and it noses over forward into the ground. I think my front lower rotors are too damaged form too many chips and scuffs from bad takeoffs or landings. Need to get by Colpar and get fresh rotors and see.
I don't know if I sent you any pics of video, but here is some:
