Hi Lou,
I had been wondering if Jim had done anything with the mini Skyscraper. As to wing area of a model for the OS 20FP, I think it could be a bit larger than 360sq in ( I know that was just a hypothetical number) when using a built up fuselage, etc.. I know John Miller has a plane for the OS 15FP/LA that has *variable* wing area, going from 380 to 400 to 420 and that is .15 FP size, so the .20FP *should* be able to pull a bit more. A Dolphin would be a good candidate I think. It is closer to 500 sq. in. I think.
Anyway, I have always heard that people in WAM would use them, and similar planes to fly in "A" Stunt. A Veco Lil' T-Bird would be good, but smaller, I think.
I *believe* the 20FP could handle a 450 sq. in.-475 sq, in. stunter if built light, using appropriate size lumber for a .20 plane.
I would like to see the numbers for a Skyscraper reduced to 48" WS from the original 60". I am not well versed in figuring stuff like that.
There are several planes I would be interested in seeing that are reduced for the 20 FP. Including a USA-1!
