Im currently using the 3-blade prop that comes with the RTF alpha 60 (12x4 3-blade). Now, i was told by someone to buy a couple Master Airscrew 12x5 props. Im just wondering what changes i should notice with this prop. I understand the pitch and diameter effects, but going from 3-blade to 2-blade stumps me. Thanks
Don't buy a couple.
But do buy a couple of different props.
My OS60 on the Skybolt works well with a number of props. A number of them are 13x6. A couple of those are Master Airscrews. There isn't a magic prop or mfg or number of blades.
The manufacturer isn't really a deciding factor. Nor is the style or shape of the blades.
You'll find that the pitch matters but not by itself.
You'll find that the diameter matters but not by itself.
You'll find that the number of blades is actually not very significant. It'll only reduce the number of samples that suit your engine. For example, there probably aren't more than two or three 3bladers you can even buy that are going to come close to suiting your 60.
What matters is the individual stick with a hole in it that you've just bolted on your engine. And the conventional sound byte wisdom about props really doesn't help sort out or predict the gamble we take when we strap any prop on that engine.
