Duc Propellers, now entering Corvair testing.

.

Builders, 

 

Pictured is a two blade, hollow carbon fiber ground adjustable propeller, tailored for the Corvair my the French company Duc .(Pronounced “Duke”)  This prop in my shop is the result of extended conversations with the staff of Duc. This is just the first combination to be evaluated, and the results form this will refine future tests, including the possibility of an inflight controllable model.  Projects like this are part of the reason why I got our own in house test Zenith 601.

As we gather flight information, I will share it with builders here.  For now, special thanks goes out to two members of the Duc team, Gaetan Fouozing, who runs the US sales office out of Sebring Florida, and Michael Derderian, who was our engineering rep from the Factory.  Both of these men have put a sustained, serious effort to advance this project.  Many old guard Corvair builders  know that I have been a dealer for or an employee off many well known propeller companies.  They all have particular strengths and unique  designs which excel in particular applications, but most people are yet to understand how the individuals in the companies make the difference on if the capabilities of the companies are accessible.  There two men really know their companies products, and have done an outstanding job advancing this project.  More news as it develops.
