Adapted from Granville Brothers Gee Bee Model "D" Sportster.
Span 53 1/4 inches (Wing plans I used are from the Bordak P-40 kit, modified for a straight leading edge, constant chord, and I rerounded tips to match the Model D shape which has wider ailerons.) The dihedral was increased to 7/8" each side to compensate for the higher thrust line. The straight leading edge and change in the aileron size has increased the wing area to about 580 sq in. I increased the stab/elev area to match the ratio on my Vector 40, which has about the same moments. Finished the plane weighs right on 50 oz, which gives it about 11.6 oz/sqin loading, or 8.6% of wing area loading. (No expertise here, just following what I read.) Power is a modified LA46 on 15% with castor added to bring the lube up to 22%. Gonna start with a 11X5 Pro Zinger and 60ft lines. I put an adjustable rudder on it and set it for about 1/8" offset with no engine offset yet. The finish is Brodak dope on the fuseelage and $kote on the flying surfaces. I used dope over $kote for the wing trim and hope it holds up. I'm waiting for a decent day here in Florida to get a flight in.
