RE: Have You Flown With 4-Blade Prop?
HI
not personally way out my range but saw this p51 fly at a warbird meeting sounded terrific
got the following details
Comp Arf mustang, it has an Evolution 80 and a Biela 4 blade
Mustang has a 24 x 10 Biela 4 blade (though there is now a 23 x 10 Mustang prop for the same motor)
