Four-Blade props?

[dothedr3w]

Anyone here running a 4-bladed prop?

Ive been looking very closely at the Luga/NR 3-Blade to use with the Edge Performance 912STI, but I called them and they actually recommended the Duc 4-Blade Swirl 3. Thoughts?

by them do you mean the engine or prop people;
it would be interesting to know how much testing with different inputs both of those manufacturers have done

My apologies, that was the recommendation from the Engine Mfg.

I don't see a problem, especially for a limited speed range.
