Yeah Doug the high pitch Magnum 65-105 I think that was the numbers. I also added aerodynamic speed cuffs to the spinner at prop blade outlet to help with the large drag disc created by the Ivoprop design. The newer design is supposed to be a lot better, the older props were much better suited for pusher aircraft. We have the newer design.  But will keep a mental note about changing pitch if not able to get good power at higher speeds.   Thanks, David.

David; you also no doubt have the "high pitch" IVO blades with the "plus" on the hibs, right?  My FWF (Tommy James Glastar) came w/the low pitch blades so I will fly initially with them and then buy hi pitch or switch to Cato, etc.  Tommy said to to fly his he had to add pitch going down the runway to increase thrust as airspeed increased.  Ross Farnham w/ turbo Subie 6A has said similar things in the past as well...
Be safe out there and have fun w/it!
