Tru-Spin Balancer

Du-Bro's Tru-Spin Prop Balancer is the most precise balancer on the market. NEW specially designed locking cone securely centers and locks props on to the balancing shaft for utmost accuracy. Each cone is carefully inspected on a calibrator to make sure it is running true. The balancing shaft is manufactured out of hardened material and then is centerless ground giving precision balance every time. The prop balancer's aluminum wheels turn virtually friction free for precision accuracy. The Du-Bro Tru-Spin Prop Balancer will balance model airplane props of all sizes and weights, boat props, spinners, car wheels, helicopter rotor heads, jet fans, fly wheels, etc. Each balancer comes complete with easy to follow assembly and prop balancing instructions. A truly precision instrument built for the modeler who expects the very best.

Sig Fan Balancer

The SIG Fan Balancer is a precision, high-tech instrument capable of detecting the smallest out of balance situation. It all starts with the shaft. The shaft on the Fan Balancer is made from high-speed steel (the same steel used for drill bits and machine tools) manufactured to a straightness of 1/1,000 mm and utilizing precision machine ground ends. Then the shaft is suspended between two powerful rare earth magnets. All that would make for a good fan balancer but at SIG, we went the extra step. We added an adjustment screw so that you can precisely adjust the spacing so that only ONE end of the shaft is touching a magnet. This provides for the least amount of possible friction.

Power Point Precision Magnetic Balancer

Precision ground balancing shaft, held between two powerful "Ceramic 8" magnets allows shaft to "float" for maximum sensitivity. Inexpensive and easy to use...essential for every modeler. Reduces prop vibration-reducing engine wear and prevents structural damage. Can be used anywhere-on the workbench or at the field. Constructed of long-lasting, high impact plastic and Nickel steel. Includes instructions explaining how to correct out-of-balance props, and even how to use the balancer to determine wind speed.

Can also be used to balance boat props, car wheels and tires, ducted fans, spinners, nose weights and more! Balances up to 24" propellers and any size wheels and tires.

Hints from Dave: Remember your physics, it requires energy to make a sound or shake an object back an forth. That vibration or sound energy (sound often caused by vibration) is energy that is not being used to turn your prop. It has a cost in battery life, top speed, rate of climb, almost any performance metric you can measure is injured by out of balance propellers and spinners.
