one third scale GP pitts?? (I LOVED that bipe!)
Correct incidence for the G/P Pitts and Christen Eagle as follows;
Top Wing: negative 1/2 to 1-1/2 degrees
Bottom Wing: Zero
Horizontal Stab: Zero
Engine: Zero up and down, right per manufacture installed firewall.
at minimum, zero incidence everywhere EXCEPT the top wing
I'll bet it'll be more fun to fly this way
