Hello,
I know that many of the top fliers use 3 blade props on their stunt planes. Being that I've only been back at c/l (from the 60's) for a few years now, as always, I'm curious as to the reason(s) for such things.
Perhaps someone could explain the advantages of a 3 blade prop. More thrust? Downhill braking?
Also, is there a point in the weight of a plane that those above that point perform better with a 3 blade? I do remember using 3's on 1/2 A planes.
I know 3 blades are more expensive and I haven't seen very many offered by different prop makers. Carbon fiber 3's are what I've mostly seen on the competition planes and those are pretty pricey.
Would there be any advantage to using a 3 blade on a sport/competition plane such as a Cardinal or Score? How about a Vector 40?
Thanks in advance for any information and opinions.
Joe
