I probably am overpropped at static and low speed.  I told Clark Lydick to build me a speed prop. I figured that being overpropped on take-off doesnt matter if you have lots of HP and can get off the ground in 1200 ft and climb like a banshee anyway. I'll be sending the prop back for adjustment once I get solid numbers, but I don't think I'll want him to cut it back much.

What sort of top speed, and cruise speed do you expect?  What would be common for an O-360 powered plane?

I used to think the same thing (draggy airfoil)  but I think the problem with RVs over 220 is related to wing / tail / fuselage incidence.   At 220 I get the visual impression that I am in a dive during level flight.

 

The early Citation jets used the same airfoil as the lowly RV.
