I’m in study mode for my potential project (scratch-built) and have spent maybe a hundred hours of my surgery recovery time reading all sorts of threads here. I could probably go another couple hundred hours, but my eyes are turning into BBs.
But now I’m to a point that I have questions regarding modifications to the stock super cub. For reference, I’ve been pouring over the Northland drawings and I also am studying Wag Aero 2+2 drawings. I’m familiar with Bugs66’s website and have downloaded and studied many of the drawings there.
So, three (probably) unrelated questions:
1. Has anyone tested or given thought to an airfoil shape on the super cub tail? Would there be any advantage in the slow-flight regime to having an upside-down wing shape?
2. The Wag Aero 2+2 wing drawing looks identical to several squared-off super cub wings I’ve seen, but the ailerons remain in the same location as found on the bow wings. From what I’ve seen, moving them toward the wing tips is a common modification. The question I have is what, if any, structural changes are required in the wing to do that?
3. I’ve read a lot about Keller flaps and think they are extremely cool—probably too cool for me. I see he has a patent on them and I can see why: they are elegant and complex. Maybe at some point I’d spring for them in years to come. But, in the meantime, would there be any benefit in trying a single slot flap? It seems mechanically fairly simple. I’m wondering if it would be worth the effort compared to the standard flap design.
FWIW, I started out committed to the idea of keeping things simple, tried, and true. But some of the discussions here make that hard….
