Except for nose-over tendencies on landing, I really can't fault the flying qualities of mine. It'll never be a pattern ship, but its a good honest sport flyer. Loops, rolls, spins, snaps & stalling manoeuvers are all predictable & safe, plus it's stable and tracks well. Really nothing to complain about. I do use aileron differential, but no other mixing. I did have issues with the undercarriage mounting blocks breaking loose, cracking of the gel coat on the fuselage, and poor fitting ailerons, but no issues with the flying. Strange how we could have such different results.
