while the reversed aileron theory is good, I would suggest that this may be the first time for smoggyboy to be flying a 4 channel plane. if you don't make the plane square and it rolls without any input at neutral time, i would say that it is possible that no amount of rudder to right it. Remember that this is a low wing, low dihedral plane. You can't expect it to react to rudder inputs like a trainer.

so my 2 cents is that the model needed quite a bit of aileron trim to get it flying hands off. Because Smoggyboy used the rudder instead of the aileron and the fact that this is a low dihedral, low wing plane, means that the plane may have yawed but not rolled.

smoggyboy - you were turned on as well... hmmm... curious! lol!
