Buy a 52 x 42 to 44 prop for climb prop. I used those pitch numbers and got 1000 fpmclimb solo and 500 fpm better max weight from a 1915 cc VWengine, before changing to a Corvair Max speed was 145 mph. Now if you want to have several different props available in one, do as I did and order a Warp Drive 2 or 3 blade (3 blade is smoother and gives better climb) so you can ground adjust it. Then test the adjustments you want to make,
I tried Warp drive and Ivo props on my KR with 1835 and a 2180. Warp came up with, I needed to round out my tips ($85 extra) I had told them the type of plane I was flying in the beginning if I needed that they should have said something then, So I felt they should eat the cost because I would have to pay shipping. They said no so I sold it to a friend with a Volksplane and at 80 mph he was happy. I tried Ivo and it would stop performing at about 135mph. I talked with him at Sun& Fun. I installed the in flight adjustable prop and after about three months of testing he gave me a full refund including shipping. My best luck was with Sturba He told me with all the variations in engines he would over pitch and after testing he would cut it down. This was in 1995. He did and it performed well. When I changed to an 0-200 I went with a sturba prop. I have Les Palmers KR here with a 150hp EJ22 and am testing with a Sensnich prop. After I find the best length I will order one of his props again. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
