Ok, on Aeronca total drag area probably about ~ 6-8 sq. ft. and that is why this aircraft has wing incidence of 1°, AOA at 85 MPH = 1°, 75% power = 47 HP., 1200 lb.
Skyboy drag area is ~ 16 sq. ft., wing incidence 4.5°, AOA at 85 MPH = 4-6°, 75% power = 75 HP, 1200 lb.
Theoretically if drag on Skyboy will be reduced by 50%, then this airplane will fly 85 MPH at 50% power = 50 HP and AOA will get to 1-2°.
If I understand this correctly drag difference on the wing at different AOA (1-4°) not very big deal at all. Problem is coming from engine/fuselage/landing gear.
