ouch, nice crash! the SingWing is a nice little flyer isnt it? it does have some terrible stall tendencies, and a lot of folks have problems with death spirals, but a light touch on the rudder stick and its not so bad. its more fun to fly than the AA i think, plus the guts are good for a more conventional rudder/throttle setup, and the gearbox in it is a sweet find (the only other 7mm gearbox that can be bought that i've found is 25 dollars!). not bad for a 20 dollar plane.

interesting about the winglets causing problems on the SW. maybe the design of the wing, the dihedral lines specifically, make the differance. could be prop torque too, swinging a single huge 4.75" prop compared to two counter rotating smaller props can make a massive change. did you cut the SW wing off to put the Strato wing on?
