Well Paul I was not planning to turn the wing sideways hanging out the window. I only want to know the force at the servo connected to a 2 1/2 by 20” aileron deflected 30 degrees.

I just finished driving down the road at 55 to 60 mph and the wing is very stable and secure. A slightly better arrangement to make sure the wing is parallel to the slipstream would be desirable but probably not necessary.

I am leaning towards assuming that servo current is proportional to the mechanical force against the servo. If data cannot be found the assumption can be verified on the bench at a later time.
