RE: U-Can-Do 46
i don't think there really ever was a true wing problem, most of what happened usually sounded like it was high speed flutter, whether or not it was ever directly stated. I DID loose my first .46 due to a sort of wing failure, the hold down block for the wing came unglued, inflight...
as far as the tail, it is a weak design near the fuselage. not something that will affect flight when it fails but still annoying. (I've flown my .46 with the horizontal stab basically free floating!!)
