It is very important to ensure that anything rotating is properly balanced for smooth running. I made this cheap prop balancer using an old heli tail, new Trex SE 450 feathering shaft, plastic plant support rod and a wood block. Posted Image Friction is almost non-existant and balance is perfect. (Prop is for my Pitts bype. :wub: Love that kite! [RAF for plane 'Birds' are missiles!]) For my big Spitfire props I use the internal plastic adapters provided to fit to the blue prop adaptor. Works fine! ^_^ I always try to remove material from the heavy blade when balancing - helps to keep the weight down a little. New props always seem to need edges smoothed and the surface often leaves something to be desired. I take the prop sizing letters (i.e. 8X6) off of the heavy blade first, usually makes no difference, but I can then see clearly which is the heavier when I have it off of the balancer for sanding. Takes time but the result is a smooth running motor. B-) Tom. |
