Had a fellow club member build the leading edges on a ultra sport "sharp" plane was almost unflyable. I test flew it,..... made the runway intact after lots of expected vector changes. The leading edges are round for a good reason.
I have a MOJO 60. Paul Swany has designed a great fun fly toy, build and fly it as instructed then after gaining a little time on the plane you can always tape some tri stock on and give it a go.
