Now since I am a scratch builder, I change things to hopefully improve the end product. The best Pitts that I have flown has been the Cermark Pitts by Dave Patrick. So I would love it if my Eagle flew as well.
Here are the incidence #’s on all three planes.
----------------------TW-----BW--Stab-motor---Dihedral
Cermark Pitts-------------0------ 0-- +2----0 ------- ?
Pilot Eagle----------------0------ 0--- 0---- 0------- +1
GP Christen Eagle-------+1/2---(-1)---0----2.5 down- +5
My project -------------- 0------ 0--- 0---- 0------- +2.5
Am I on the right track or am I over looking something?

Hi TC!
Glad to hear someone else scratches too..
Am doing the Pilot Pitts in the 1/3rd size..so you can add the following to your chart.
TW = 1+ BW = 0 Stab = 0 Engine DT = 1.5- RT = 3 This is from the Plans..so am only changing to more DT to 2.25 the rest stays the same. Should handle the G-62 Zenogh that way.
On the various aircraft you mentioned no notes on the airfoils, Top Wing..?? verses Bottom wing ?? This would have a definite bearing on the final result. The Pilot Pitts also has a symetrical top wing and a semi symetrical lower wing.. definately not a clark Y. Though am changing it to the same section as that of the top wing and will keep the lower wing setting at 0.
I have the Steen Skybolt that Dario B. and Lamar Steen co-designed from the orginial plans of Lamars. The following are from it...TW = 2+ BW = 0 Stab = 0 Engine DT = 2- RT = 3 and both wings are of the same airfoil.
