Interesting and educational thread.

One thing Randall mentioned that wasn't commented on was the change he made to the Hog's dihedral. He halved it.

I did this to a low wing sport plane once and the result was negative coupling between rudder and aileron. This was evident in knife edge when the plane wanted to roll towards its' belly. The effect was slight and a little oposite aileron mixed into rudder fixed it.

Later on after a mishap requiring a new wing which I built to the designer's specs, the plane no longer exhibits this adverse tendency.

Do you guys think that my experience was a normal result of less dihedral on a low wing airplane?

Thanks,
