Hello , I have a Kitfox 4 Speester with a 912 Engine and a Warrp Drive Prop.
At the moment I´m cruising with 5000 - 5200 RPM and that gives me under 100 mph ( around 90 most of the time ).
What are the experiences with that combination and would it help to increase the pitch of the prop. GND RPM is just around 5000 at the beginning of the take off.

Cheers Marc
