Has anyone ever put an inflight adjustable prop on a Hummelbird? My engine is 1037 cc half vw engine with Sweetapple wooden prop dia 50in./34deg. Think this is a small prop for higher rpm in cruise. Guess an adjustable prop would give better climb and slight improvement in cruise. Soon doing first flight in plane so I don't have any figures yet for installed fixed pitch prop.
