Hi all,

I am going to fly the new Super-Q500 class in Sweden, which is roughly 428, but with unlimited size venturi, any propeller and 20% castor, 0% nitro fuel.

I guess that you have experimented with different prop sizes. Which prop do you think would be fastest, with a Nelson Q500 engine and an FAI-venturi, if you could pick any size, manufacturer and material?
