K&B .82 Ducted Fan Motor Info?
A friend of mine has a NIB K&B .82 ducted fan motor. I tried searching here on RCU but came up empty. He is hoping to put it on a speed plane if it will handle a prop. Any info would be appreciated!!!!!

There are three sources of carbon props in the US that I know of: Steve Wilk (Eliminator Props), Mike Hazel (ZZprop - good range of AMA D speed props), and RocketRob from this forum who offers a 9x10 CF prop suitable for big block ducted fan engines on RC speed planes. That's about the size you want.

I remember when Bill Wisniewski was developing that engine for D speed (as a 0.65). Very high torque and impulse that had a tendency to break the prop as the plane was reaching speed. He put it on a strobe-o-scope and could watch the blades wobble when the mixture fired.
