RE: Have any of you run props like this?
I've asked the C/L speed flyers about it. You can run more diameter and blade area with one blade and if the engine can rev high enough there will be a performance gain. There is more vibration with one blade, and there is no way to truly cancel it out. The AMA rules book has a diagram for how to build them. The type of airframe matters too, you wouldn't put a dragsters' torque converter in a dump truck......the way I understand it the single blade idea is only more efficient [than 2 blades] in a speed application. Good excuse to build a SWR, huh?
