Help identifing a prop

[Dave Holtsclaw]

I bought an engine and the prop that was with it is new to me. Its a wood prop  7X4 with wide blades. Each blade is stamped OK and the hub is marked FLO-TORQUE   7x4  with blue paint. Does anybody know anything about this prop? I have never seen one before.  sorry I cant provide a picture.

They were a standard commodity back around the late '40s. I know I had one somewhere back then on an ignition engine. It was kind of chunky. I have seen a few in old estates along the years.

Perhaps an OK Cub prop...probably for a Cub .09?

I don't have it handy at the moment, but I think that is the brand of one of the props tested in a recent issue of Control Line World..........

This is a little late, but I accidently came across this in the July 1949 issue of Air Trails.

Evidently, "Flo-Torque" props were marketed by Berkely in a wide range of diameters and pitches and for racing, stunt and Free-flight.

(It would be interesting if this "is the brand of one of the props tested in a recent issue of Control Line World".  Control Line World would be testing a prop about 60 years old!!!

Keith,
The article I mentioned is in the Jan. 2009 Control Line World; alas, the Flo-Torque was not one of the props compared.  Sorry for the misdirection..........
