Re: Pictures prior to Oskosh
Hi Steve and all,
To answer your specific question about our propeller specs:
We have tried 3 props with different geometry. The final one is also an MT prop wit 2050mm (81") dia and 1200mm pitch (47") pitch.
We get a cruise speed at standard prop 2100RPM setting of about 95 to 100MPH.
See this link to the diagramm shown on the Rotec website with lots od data also of the previous tred props:

Concerning the gear leg lenghts: ours is shorter than yours. The plans were later modified by Jeff Shoemake with an elongated gear to compensate the lower thrust line of the Rotec for prop clearance.
As we have the 24" Bendix wheels, the angle is just right for smooth stall 3-point landings.
Happy building!
