Default 3 blade vs. 2 blade rule of thumb
Hi all.

What's the rule of thumb regarding "downsizing" to a 3 blade prop, for the diameter of the prop?
I have a Super Tiger .90 that I've always used successfully with 14/7 propellers.

What would be an appropriate 3 blade equivelant for this engine?
Also, other than ground clearance issues, are there other tradeoffs/benefits to consider with a 3 blade-er?

I'm considering it for a Sig 3-D Mayhem.

Thanks.
