RE: Propeller load factor...does this really work?
This is exactly the info I've been looking for. I've been looking at prop selections for my Supertigre S61 ABC and using that formula came up with the following. The instructions said to break it in on an 11x8 and here's how the rest of the props in my "collection" stack up against that size.
12x4 28
12x5 29
11x8 30
13x5 31
13x6 32
14x4 32
Looks like all these are relatively close.
