Default RE: My new speed plane...advise needed

Maybe I should sharpen the leading edges on it?

Round the leading edge of the gear, leave the back square for Camm effect. You don't want knifes flying at 170mph.[X(]

I think a cowl would get you there, you're up to a speed where drag reduction is far far more important than any Hp gain you might be able to get. Maybe a little tear drop flaring behind the engine cylinder.

I wouldn't sharpen the leading edge of the wing either, that will only give you a pitch sensitive plane. Sharp fronts don't help until about .85 Mach. Sharp trailing edges of the wings will help though.
