I've been looking around for info on Junkers flaps, but everything I've found so far is from the 1930's and isn't necessarily all that precise. Plus I'm thinking with CFD and all, there might be foils especially designed for it. For Part 103, they are flaps that the will be recognised as such, maybe making things look a bit less high tech. And if I read, was it Hoerner's?, correctly, less drag for the additional lift than some other types. Seems like they might be simpler to build than some of the other flaps that can get the same sort of high Cl, plus allow a bit of negative when trying to escape sink.
Anyway, anyone seen more recent info about them.
BTW, has anyone seen info about two part symmetrical airfoils, which are sometimes used for sailboats. One of my persistent fantasies is to build the highest pointing, fastest Footie. http://www.sailfootyuk.com/
