RE: Did pattern fliers used to use variable pitch props?
There was one available back in the early/mid '80s.
I saw Steve Helms use one at the World Championships in Pensacola in 1983.
There were some issues with them shedding blades.
For that reason the one Helms used was not available to the public.
That about all I know which isn't much...
As usual![sm=bananahead.gif]
