Here’s a great little video about how to statically balance your KievProp – ie off the aeroplane. I suppose the technique could be used for any type of propeller. It certainly works here!
As a matter of interest, you can also dynamically balance your propeller – ie when attached to the aeroplane, with the engine running. However, this does need a piece of electronic kit (which is not cheap and simple) which in principle works in much the same way as the static balancer.
Overall, for an inexpensive and excellent balancer, the static approach works well.
PS – be sure the carburettors are correctly balanced (ideally with the engine running) and the blade pitches are all exactly the same…not even a skerrick out!
