Mini torque gage 9

[insideman]

I need to find or make a mini torque meter or gage. This will be used to measure the reaction torque of tiny motors driving propellers and ducted fans. Say 10-20 watts output at 10000-20000 rpm.

Very little space is available. About one inch diameter by one inch long to fir inside the fan tailcone. Smaller is better so as to avoid restricting cooling air flow past the motor.
