I just received and installed the 5 bladed KievProp that I ordered from you. The performance is so incredible that I need to tell you about it. I fly an AirCreation 582 Clipper, two-place trike. It came with an Airplast 4 bladed prop on it. This is supposed to be a top notch, high performance, quiet prop. It was pitched at 6450 RPM at full power climb out. I could cruise at level flight by myself (I weigh 190 lb.) at around 4800 RPM, with a 200 lb. passenger at around 5700 RPM. I could get around 800 fpm by myself, and 600 fpm with the same passenger and 16 gallons of fuel. The Airplast prop got damaged and there was no way I was going to pay the French over $2300 to replace it. You sold me the 5 bladed American manufactured blade to hold me over until the Kiev came in. Its performance was just a little less than the Airplast and slightly more noisy at the same pitch. The Kiev came in and it was like putting a turbocharger on my trike. Taking off, I have the feeling that my craft wants to flip over backwards. Pitched at 6450 RPM, I don't yet know my full power climb out rate because my VSI redlined at 1000 fpm. I'll get it with my GPS later. With a 200-lb. passenger and 16 gallons of fuel, I get 900 fpm. My cruise rpm went from 5700 rpm down to 4900 rpm with the same passenger, by myself, 4800 rpm down to 4500 rpm. The prop is so quiet, we forgot about it. The fuel consumption per hour seems to be about the same as the Airplast. I highly recommend this prop for anyone who wants to increase the performance of their craft.

"I put one on my trike and it was like moving up to a 582 without having to buy one." --Bob Bullock, Watertrikes.com
"I just put a KievProp on my RANS S-10. Right away, I noticed a difference. The low-end vibration that I had with the Warp Drive, 582 B Box was gone. This prop is very smooth and has increased my performance by at least 10%. I can't say enough good things about it! Thank you!" --Jeff Howell
"I noticed an increase in the thrust right away. I never had to ride the brakes while taxiing before. I was also surprised by the increase in climb. It really got my attention! And with less noise, my wife doesn't complain when she goes along!" --Bill Neff
