I'll post the results.

Tnx!"

"Strange loiter for tri-copter. After lots of flying and testing with my tri-copter. Stabilize, RTL, Land -> very good. However I found this strange thing in Loiter. When switching to loiter, it stays in place very good, but... when turning slowly…"

"Maybe a bug... Flying mostly development code, I've flown 3.1-rc7 with my newly build tricopter. All flies very well, but in Loiter, when trying Macro's trick to let the copter spin using Yaw, the motors sort of shut down and copter went to ground.…"

"Latest from master flies great. Tested v3-rc3 with stock params on 3DR Quad and 880 motors.
- Stab. flies as usual. Still gaining height when full forward and returning to level. (maybe tuning will help)
- Alt Hold. Flew several accu's just in…"
