RE: Which Size Vess Prop?
You should know that Vess has some new props out, at least I believe them to be available at this time, and they are thinner in design than his current props. I heard that Quique flew his turbine powered Yak on one several weeks ago and he was very impressed. You might want to call Vess-Aero and find out. Let us all know if they are out and available.
