Torque Meters
A torque meter is a tool that allows one to measure the power of a rubber motor. With one an aeromodeler can wind the rubber motor to the same torque for each flight regardless of temperature or turn number. This allows for consistent power patterns and maximizing the available power of the motor. Once one establishes the breaking torque of a particular batch of rubber you can wind closer to that point with confidence.

Building your Own Torque Meter:
Herb Kothe; one of the best rubber flyers around, shows how to build your own torque meter. The one described is for large rubber models. There is information on a 20 in/oz meter which would work for P30.
