Sorry if this comes thru twice, my confuser acted up.

My engineeering group is building "little squares", they should have
the flying surfaces done tomorrow. We're using a 6% simplex airfoil.

Gee, I feel for the 40 + foot ceiling problem, we're flying in a 22 ft
gym with llittle tornados under the ceiling vents strong enough that
they can blow the plane to the floor from 20 ft up.

As part of the course, they are having to design their own props using
cottage cheese cartons or sheet plastic formed on a tincan in an oven.
 They will have to calcualte tilt angle to get an approx helical
pitch, then mount with bamboo spars fitted toa bit of plastic stir
stick for the hub with the shaft running in a wire pigtail. Poor
kids. (:_")

I'm thinking of building a static thrust gage, any ideas or thoughts ?
