Thanks AJ...

But even flying the plane straight not using the ailerons at all it was very unstable. Tried to straighten out with ailerons and it did nothing.

I will try taking out the ' dehedril' and see if that works.

By the way the cub is a nice flying plane ... flew that today also and it flys better than the Decathelon.

Oh... one other questions, how much of the wing did you cut out for the ailerons? Did i cut enough out?

P.S. do you have any pictures
