I have this plane.

I can do a flat spin upside down that kind resembles a kite spinning rather than a true flat spin. Right side up is not going to happen. I worked on moving the CG back until I finally got a good flat spin and one time the engine died. Well, it came out of the flat spin OK but, when I started to turn slightly towards the runway it snapped. Again I corrected and this time with only a little up--Snapped again and again and again all the way to the ground. It came down slow so it was and easy fix. CG is now 4 7/8" from LE any farther back and you will probably start to have the same problems I encountered. It was 5 1/8" when it would not recover. I even tried a little throttle to help it out some. but still didn't work. The Magic Extra will not stall at the tips like most aircraft. So, "Snap Rolls" look like a wild roll and Flat spins -- kite that is spinning. I will say it's still fun to fly.
