1/2A Nut,

I'm afraid to say I haven't flown this airframe. I acquired this one, and I don't want to fly it as it holds special value to me. Nonetheless, the prop is 6 1/8". Can't remember the pitch.

Cox made a 6x6 for the Sportsman powered Comanche CL planes.
I sourced a bearinged Olympic for swinging vintage wood 10x3 props on a floater.
5.5 x 7 would yield a theoretical speed of 133 mph at 20k rpm. Thumbs Up
