We test flew a friends last weekend, with a pair of Magnum .91FSs. maybe just a "shade" overpowered, but it flys real nice. Some stall tests indicated a "really nasty" stall break. You better have altitude when you stall test it. A little upward reflex in the ailerons softened the stall, but it's still pretty nasty. Fly really fast with the .91s, but not really overpowered too bad. Jumps into the air after about 20' if you don't hold it on the ground. Landings were a thing of beauty. At about a foot of altitude, just released the elevator and it settles down to smooth wheel landing. He is using Spring Air retracts with the ASM struts.
