Thread: 14/19 impeller???

is there a difference in 14/19 and 14/19R?

Technically, YES! The difference is that Riva places the props in a device and pitch blocks each prop. Ensuring that the pitch is a true 14/19. So the R type impellers only come from Riva. You don't have to buy a 14/19R. I bought a 14/19 and had Jerry pitch it to my mods and it works great.

It's the same prop with the same root angle and everything. There is NO difference with the two. Only that the type R impeller is pitch blocked and comes from RIVA.
