Sig Smith Mini Plane?
I haven't flown the plane.
However, Harry Higley in his book "Bipes" had the bottom wing set at 0 incidence and the top wing set at -1. This seems to take care of the ballooning recognized by Harry and referred to by elmshoots.
I currently have mine setup up for 0 and 0 as called for in the plans. I used robart incidence meters for the set up.
The small bipes can be sensitive. I am currently flying a DP 40 ultimate. It takes very little aileron to make the plane move. You ought to see it roll with full throws. I really enjoy this plane and I have been flying for a year.
I look forward to getting my Smith in the air.
