ONE BLADE PROP!!!!

[dick hanson]

OK everybody who remembers these - signify by the usual -- no response

[adrian]

this another good explanation - The reason we use two-blade props is efficiency! In fact, a one-blade prop would be better than a two-blade. Because prop blades operate in the wash of the blade ahead of them in the arc, the more blades you have, the closer they are to one another and the less efficient they are at turning torque and rpm into thrust.

The control line speed flyers using one bladed props are turning them in excess of 30,000 rpm !!! And that's a bunch of R's.

Though it is counter balanced, think of the oscilation from drag and thrust pulling the shaft out of whack.... as opposed to having two or three blades equally thrusting forward on the motor shaft... think about that. There is more to it than just counterbalancing.
