I have built a 3 blade prop that Gary Hertzler designed. My take off is
1500' with 2 aboard and rate of climb is up to 1200 FPM. Top speed is

230.

Cross country I am 220 MPH at 3500 RPM burning 4 to 5 GPH depending on

how

high I go. This winter I plain to install reground cams and a new

canard. As

well as some other cleanups.The prop was designed for 4,000 RPM so

hopefully

a little more HP and less drag will bring the speed and RPM up and give

a

good speed increase. I lost about 5 MPH with the 3 blade, so I may

rework

the 2 blade for racing. Hope to run the Sun 100 but my second child is

due

in May so I may not make it. I have 60 hours on it now and the engine is
been trouble free. I have never even looked at the plugs and the only
maintenance has been 1 oil change. I run the hell out of it. Time will

tell

if it will take it.

It is a mix of Subaru parts. Late block early heads something like that.
