What prop are you guys using with a C-90 or C-85? I have a C-65 now and am getting real serious about changing my engine. We have a 1,200ft strip at home. One person is fine now. It would be nice to continue to haul the neighbor kids around. The C-65 did fine till they got above 70lbs or so.Craig________________________________________________________________________________Date: Sat, 11 Dec 2004 23:14:05 -0800

Consider going to a two blade Warp Drive prop. You can pitch it to find thebest combination of climb and speed. When I switched from a wood Sensenich (Imay have been overpropped) the difference was incredible. The A65 powered Pietwent from anemic to a blast. At gross (1180#) it now climbs as it did beforewith no pass. and minimal fuel. I used to use a sprayplane type of t/o run. Holdingthe plane on the ground with the stick forward to get up some speed. I wouldusually move the stick forward after the tail come back. Now if I don't movethe stick forward the instant the tail comes up, the plane starts to fly. Just put my skis on yesterday, waiting for it to stop snowing so I can go flying.Shawn WolkC-FRAZ________________________________________________________________________________

Craig,I have a new Warp Drive to use with my Corvair engine. I bought the 68" dia. andbeing ground adjustable, I can make it any pitch for what ever purpose. WilliamWynne gave it high marks as that is what he had used on his Pietenpol soI ordered it from him.Alex S.-------------- Original message -------------- > > What prop are you guys using with a C-90 or C-85?

The warp drive is a 2 - blade 72" HP blades and HP hub. The guys with CorvairsI assume are using a 3 - blade 68" HP blades and hub. If you want to havethe ability to hand prop, you really want a 2 - blade. The guys at Warp drivewill likely recommend the 2 - blade up to 100 HP. Then the 3 - blade for 100 HPand up. I am sold on them. The nickel leading edge that most people seem to want slowsdown the order/shipping time. I have my blades w/o this. I put the leadingedge tape on and have found this works quite well, even in the rain. I had toreplace one leading edge tape only because i installed it poorly.Shawn WolkC-FRAZ Pietenpol AircamperC-GZOT Skyhopper 2________________________________________________________________________________Date: Mon, 13 Dec 2004 23:58:00 -0800
