I found the Tony article in January 1970 Flying Models, and due to lead times for publication at that time, it existed during the classic era and would be legal also. It has the same thicker wing as the published 109 and P-63. The wing airfoil, to me, is so different, you have to wonder if that makes them two different models. And add in the different tail shape of the published P-63 and the kit version. I think the published versions would be better performers than the kit versions due to the thicker airfoil. The kit wings were probably victim of the "lets make the wing thinner so we can get all the wing ribs on as little balsa as possible" syndrome. Go to the Outerzone plan site and you can compare the wing plans.. You could make a hybrid, and use the published wing in the kit fuselages?? If you want to do the P-40, pick a rib near the root that fits and use it for the whole wing. . So, if push came to shove, I think the Midwest kits are different enough that they should NOT be classic legal, but are N-30 eligible, but with that thin wing, are at a competitive disadvantage to other designs at the time. The published designs are, or course classic ear legal, but since they existed it would be a legal period modification, I think, to use the published wing in a kit fuselage and such, if you have the parts. I'm interested in how the published designs would fly with the fixed flaps, and with proper balance and set up, they might do pretty well.
Type at you later,
HAPPY 4th of JULY!!!
