It is almost as easy to make a dyno as it is to make a test stand.
This would be a pieces of cake for you. You don't really need to measure
the trust. That is handy to test props but not really necessary.

The cafe foundation used a hydraulic cylinder with a pressure sensor to
measure thrust.  They attached a cable to the landing gear of the plane and
then attached it to the hydraulic cylinder that was attached to a heavy
truck.  Look at the 5th page of http://www.cafefoundation.org/aprs/epg.pdf

You have to be careful optimizing for static thrust. It can be misleading. 
Particularly with rev limited piston engine.
