KR>prop unloading

[Brian Kraut]

I have a VW 2180 with a Props Inc.  prop.  I believe it is a 52 X 49 prop.  It 
turns 3,000 RPM static, but it only unloads to about 3,100 RPM at full throttle 
in the air.  I am also only getting slow cruise speeds and about 700 FPM 
climbs.  I have heard from one other person that has used one of these props 
and got similar results so he switched to a Sterba prop and got better climb 
and higher RPM and faster speeds in cruise.  Have other people experienced bad 
results with the Props Inc. prop?
