This is a prop balancing rod specifically for the props on the Yuneec Q500 series quads. It has LH and RH thread on opposite ends and can be used with different balancing systems. I found the Q500 props to be very well balanced from the factory, but a couple needed just a very small piece of Scotch tape to balance. Having well balanced props can help to reduce vibration fatigue cracks in the airframe and help it fly smoother. I have a Du-Bro balancer (not included). The balance rods are $20 new. will sell for $15 shipping included.
