Blown motors cause serious damage to rubber powered models. A Torque Meter with Blast tube protects the fuselage from blown motors, while providing an accurate measurement of the "power" wound in your rubber motor. Trimming a rubber powered model is simplified with a Torque Meter by allowing you to accurately duplicate the "power setting" flight after flight regardless of the number of winds. The BMJR P-30 Torque Meter is calibrated between 0 and 12 in-oz and is the perfect size for use with P-30 class rubber powered models.
