Friends,I am ready to mount my 95 H.P. Corvair engine on the test stand I built to Pat Panzera's specs. Question is, what size and pitch prop is recommended. I cannot find what prop Mr. Pietenpol used on his Corvair powered Pietenpol. I recall reading he wished he had a different pitch. Does anyone recall what he used? Any suggestions would be appreciated.Thanks for the assistance.Alex Sloan________________________________________________________________________________

Alex,According to "How I Make Wood Propellers" by Al Schubert, the prop was 63inch diameter by 35 inch pitch at the tips. Al made two props for Bernie'sCorvair powered Piet.CheersPeterWonthaggi, Australiahttp://www.cpc-world.com-----Original Message-----

I'm using a 66x29. If I was to do it over I'd go with a 64X32 but I'm suremy 66x29 will suffice... my engine is a '65 110 with OT-10 cam.DJ----- Original Message -----

no particular reason really..... I saw a couple Piets on William Wynne'swebsite that used that size, and the guy who made my prop also thought itwould be a good size. I had my prop made by Tennessee Propellers.Since then I've fond that most Corvair powered Piets seem to go with aslightly smaller diameter and more pitch. I have plenty of static thrust,but I'm a little bit concerned if it'll produce good thrust once the planeis moving. I'm pretty sure it'll be ok and I'll certainly have awesomeclimb performance which is always good in my book.My dad is giong to use a Tennessee Propellers 64X32 or 62X34 on his 'Varpowered Celebrity. He'll be buying his prop before I fly my Aircamper soI'll be able to try both sizes.DJ----- Original Message -----
