I have to agree with Charlie concerning the Edge and Extras. I have an Edge that would float forever with a high pitch prop. I had to beg it to land. But just dropping the pitch and increasing the diameter some fixed the problem and turned the plane into a different bird.

On a pattern ship I had, I used spoilerons so I could better stick the landings. Because of many factors like engine, prop ground clearance and landing gear the easy solution was to setup an elevator-spoileron mix. As I applied up elevator to hold pitch on approach the spoileron would raise just enough to kill some lift. I loved it and the only time I didnt use the mix was on calm days.

Cheers.
