AVIA Prop
I flew the RV6A that you are referring to back in 2003. You probably will hear from Russ Davies. (sp?) I was impressed at how well it performed with a 150hp O320. Russ did sell the 6A and the new owner totalled the plane a short time later and it was the only known RV using that prop.
It was weird watching the little vanes rotating at the aft end of the spinner when the flight loads changed!
The only thing that bothered me was the TBO, something like 700 or 800 hours. I don't know if that still applies to it today. I tried finding it online to show a friend and couldn't find the same prop listed on their website that was applicable to an RV & a C172, at that time.
