72FM8 Series Propeller
UPDATE

We have some performance numbers HERE!
We have a recap below!

Ken Barto's RV-6A with the new propeller before flight testing. If you look really closely you can see the strain gauging.

Here is a close up of the new tip shape and strain gauges. Why the different tip shape?...AND, why is the final product slightly different than this picture???

This is how we really design our propellers!!! Actually, we are cutting down the diameter to test the repairability of the propeller. From left to right, Ken DeGraff, Terry Griffe, and Ken Barto.

UPDATES:

19 April, 2000
We heard a rumor from several customers, at Sun N Fun this year, that the 72FM series propeller is not recommended for aerobatic use. THIS IS NOT TRUE! The 72FM series was fully tested for aerobatics and is safe to fly.



August 19, 2003

We have a beautiful week in PA to test the 72FM on the FADEC system. We are testing as we speak. Hopefully we will have some good news later this week.






Let's recap where we are:

The 72FM propeller is now available for sale from Van's and Stoddard Hamilton for all O-360, 180 HP Lycomings. Contrary to what you may hear, the delivery is about 8 weeks after our receipt of order.

The final configuration is a 72FM8S( )-1-( ). This is a 71 inch diameter! See specific extension and pitch details on the Vans Installation Page.

As with all Sensenich aluminum propellers, this propeller comes with its' own extension (spacer) system. Please specify 2.25 inches (72FM8S9-1-83) or 4.00 inches (72FM8S16-1-83) when ordering. The mounting hardware is also included!!!

If you have a tip strike or other serious damage, the propeller diameter can be reduced two full inches from a 71 inch diameter to 69 inches. Repairs can be performed at any approved propeller repair station worldwide! The propeller pitch can be adjusted or fine tuned at any approved propeller repair station for your specific aircraft.

REMEMBER...there is NO PLACARD for this propeller!! 180 HP @ 2700 RPM!!!

We have aluminum spinners in stock! No fuss...all cutouts and nutplates done for you!

We have some performance numbers for you taken during the flight test with Martin Sutter's RV-6.
