Other Fixed Pitch Props for Aircraft over 190mph.

We have manufactured propellers for many airframes, I can't list them all but please inquire! I'll list a few common applications below in this speed range.

Tailwind 320/160

2-Bladed 66" diameter 76" pitch

3-Bladed 64" diameter 76" pitch

Thorp 320/160

2-Bladed 68" diameter 71" pitch

3-Bladed 66" diameter 71" pitch

Lancair 235/320:

2-Bladed 64" diameter 78" -80"pitch

3-Bladed 62" diameter 78"-80" pitch

A three bladed is much quieter and smoother, you’re able to run a smaller diameter so greater ground clearance and it has more of a braking affect when you pull the power back. You will also see your RPM will come up faster as you start accelerating on takeoff. The two bladed is slightly faster at wide open throttle around 2-3 mph top speed below 7500’ but the three bladed will maintain its speed at 12,500’ but the two bladed loses top speed. The three bladed becomes a few mph faster at 12,500’. The climb performance between the two are very similar.

The following table represents our standard recommendations available but may vary slightly depending on the speed and specifications of your current airframe.

Nickel: Nickel is an additional leading edge protection which is great if you fly through rain, off grass or off strips that aren’t that well maintained. It is very durable and allows you to fly through rain at any RPM without erosion. If you are a fair-weather flyer the nickel isn’t necessary for your flight operations.

LET tape: We offer a polyurethane leading edge tape to protect the leading edge of erosion through rain. You can still get some nicks from small debris and rocks. The adhesive on the tape normally starts breaking down after 3-5 years and will need to be replaced. We do sell kits so you can install or replace it yourself.

Without nickel or leading edge tape the propeller will hold up like a wooden propeller through rain. You’re able to fly through rain without leading edge protection if you are throttled back below 2200 RPM. With the leading edge tape or nickel you’re able to fly through rain at your cruise throttle without erosion.

A 2.25” or 4” extension are common length extensions for this application. We require a 7” diameter mounting surface and all six lugs to protrude into the propeller at least .350”. If you have a smaller diameter mounting surface or if you do not have extended length lugs you will need a new extension. There have been many evolutions of extensions throughout the years. If your extension has both the extended length lugs and a 7” diameter mounting surface we will try to accommodate and get you all the parts you may need for install.

If you are purchasing a new extension we will need to know if you have 3/8” or 7/16” bolts. The 0-360 comes standard with 1/2'.

If you are going to reuse your existing extension we will need to know the bolt size on the prop size of the extension. Additionally, let us know if you have a lock nut on the back of the propeller bolt or if the extension has a threaded lug.

Crush Plate: We do require a 7” diameter crush plate to be mounted on the face of the propeller. We have them available in a variety of thicknesses depending on the installation. If you’re using Van’s spinner kit, the alignment between the front and rear bulkhead is critical. Just let us know and we can ensure you get the correct thickness crush plate for everything to align properly. We also offer a weighted crush plate if you need to move your CG forward.

We carry a 12" and 13” spinner. We sell a carbon fiber spinner dome, an aluminum front bulkhead and an aluminum rear bulkhead. This will accommodate a weighted crush plate if you need add one later.
