forgot to answer about the building tips. my wing was a little warped. i'd check the wing first to see that it's square. if it's not, return it. mine is flying with a bent wing so i have to dial in aileron trim to level it out. but it's a easy flyer not a pattern plane so i don't fret too much.

the plane builds tail heavy if you're using lipos and it doesn't provide room for cooling. i recommend that you open up some venting holes so that the battery doesn't overheat.
