RE: Pica Bucker Jungmeister: Over the Hump With This Kit
I always thought better to have the upper wing with positive incidence. In this manner the upper wing stall before than the lower. So the center of gravity is in advance of the lower wing, than the plane dive and it is easy to recover the stall. Other thing that i have heard is to put the wing that has ailerons in neutral or negative incidence to delay the stall respect the other wing and have control with ailerons. That´s not problem i have ailerons in both wings.
These things are maybe (or sure) incorrect and i hope that you correct me please.
The incidence in biplanes are complicated. The only thing that is true is that the experience show us what happens, and my experience wiht biplanes is nule (this is my firts biplane).
This is the reason why i will try what you say: 0º down and stab, -1º up and 2º motor down and right.
Thanks and sorry for my poor english!

I believe the Jungmann and Jungmeister had more incidence in the bottom wing. The purpose was to have the bottom wing stall first to help in snap rolls. Not sure you want to try this for the reasons you mentioned, but it could be what made these planes great out of the ordinary.
Actually I found it from a Jungmann rigging manual:
"After the center section is rigged, check the angle of incidence. It should about -1.5 degress +/- 0.5 degrees. The lower wing stubs should measure about 0 degrees."
Check out www.bucker.info. Cool site.
