mine is still flying so have loads of good experience with it.
some advice; glue the motor to the wood under it; the foam alone is NOT strong enough .
Make sure the cg (balance point) is right ; the old nicad batteries this plane is designed for are heavier then todays lipo of the same size .
I balance mine on the spar (wood in wing) with the nose a bit down.
Check if the current of the motor is right ; the standard prop is the "gunter" push on prop (most americans know it as the zagi prop)
and yes its styrofoam so its a foamy and it was my first foamy
