REFLECTOR: Aerocomposite Prop

When I purchased my kit last April after sun & fun, Velocity had a aluminum pusher prop that they were showing and testing. Has anyone heard of the results of these trials? It was supposed to be priced competitively with MT.

  I was talking to a long time Mix Master owner and asked him about the rear prop blades.  He said he never had a problem with the rear prop, just the engine - running hot back there.

  I asked the question about metal props back there, and no one could give definitive info about the problem (canard and Velocity lists).  Someone said that Mike Melville had a metal prop on of his first pushers (Vari?), he flew it and said that "damn" metal prop is vibrating and has to come off.  But beyond that, no one had any real data.

    One thing we have to deal with that tractors don't is the trailing edge wake from the wing hitting the prop.  Someone smarter than I may be able to chime in if this has anything to do with prop performance.  I know the mix-masters from Cessna had problems with the rear prop even though it was basically the same as the front, but with pusher blades.
