Powerfin Propellers
Due to the extremely high demand of the KievProp and the long lead time, we are offering the Powerfin props which usually are in stock or only take a week or two to receive.
In our opinion and experience, the Powerfin is the next best choice and value after the KievProp.
This way we can still provide you with a very efficient prop for just about any experimental, light sport or ultralight aircraft.
Powerfins are available in 2, 3, 4 and 5 blade configurations from 36" up to 75" diameter, for 10 to 120 HP engines and aircraft with a VNE no greater than 120 MPH.
We will be adding more Powerfin information to this page shortly, in the mean time please call or e-mail with the following information and we can suggest a great model for your particular application.
- Engine type, model, HP rating, direction of rotation, and gear ratio.
- Aircraft type, model, takeoff, cruise and VNE speeds.
- Very important, maximum diameter you have clearance for or distance from prop hub center to nearest obstruction in the prop arc.
- Your desired performance - maximum takeoff, most efficient cruise, highest speed or a combination?

Propeller sales continue to increase
Discover why so many sport plane pilots are moving up to KievProp. This propeller can provide you with an average 10% to 20% increase in performance, faster cruise at a lower RPM, and faster climb. Save fuel and enjoy a smoother, much quieter flight.
Each blade is injection molded under pressure, to insure light weight as well as excellent strength. A large surface area at the root of each blade assures a firm "no slip"grip to the hub. Total combined weight is well within the mass moment inertia limit that is recommended by Rotax or Hirth. Each blade is assigned a serial number for replacement accuracy.
Other Standard Features Include: Inlaid brass leading edge protection, semi-semitar tips with forward dihedral, pressure-formed aluminum hub, white or black color choice, pitch adjustment tool, mounting hardware.
Options: 1.2 or 2.25 inch aluminum alloy prop spacer, installation-ready composite 9" spinners, slip-on protective covers, 3 and 5 blade configurations ranging in diameter from 63.4" to 74.8".
Sizzling Hot Performance! Rated for 40 to 130 HP engines with a metric prop hub bolt pattern.
Testimonals
“The performance is so incredible...”
Bill Larson, 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 Arplast 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 climbout. 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 Arplast 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. It's performance was just a little less than the Arplast 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 climbout rate because my VSI red-lined 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 Arplast. 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
