REFLECTOR: PUSHER PROP

Thu Nov 12 17:59:45 CST 2009

Chuck,

What were the details on the crash in east TX, was this aircraft using a Vesta prop or what brand were they using and did the prop cause the crash? I didn't see any details in the news, it must have been only reported locally.

I called Jason Day, owner of Vesta  a couple weeks ago and he said that the FAA had asked him to not let anyone fly ac 4 cyl Lyco pusher after the fatal crash in east TX of that type of Velocity. He told me he had a few V owners who were doing  some ground testing for the 4 cyl V. I think there are some flying in 6 cylinders. 

I'm afraid that the Vesta could have the same problem that many other props have with the 4 cyl Lyco pushers. Apparently, MT had problems early on as well with this combination. I believe it is due to the highly uneven torque loadings from the 180 degree firings in combination with the blanking of the wings creating a whipping action that overloads the hub and the blades. Both MT and AeroComposite have very light and strong blades which appear to be able to handle these varying loads without damage, but they are expensive. 

I'm using a Catto fixed which I believe will handle the load from my newly turbo normalized Lyco IO-360 (max MP 36.5 in). It's a cruise prop, but with the turbo it now has very good acceleration.

What ever happened to the Vesta prop? I think Dave Dent bought one a while back. 
Does anyone know if it worked for him? Or if Dave is on here can he give an update?
