They are pretty good airplanes, but I saw the wing fold on a 3Meter FC Extra last fall. The pilot was doing a blender, rather a gentle blender, when the wing just folded. The carcass hit in soft dirt yet we were amazed at the amount of damage done...motor went back to DA, all servos needed re-gearing, cannisters are now used for scrap metal, headers destroyed. When these go in, they go in hard.

The pilot got another, but he flies it with a touch of apprehension. No more blenders, only really soft 3D.
