have a graupner 9X6 folder, with a neat aluminium spinner and back plate assembly. The spinner has a hole in the front which aids airflow through the hub assembly and through on into the nose vent holes. I think the spinner is from the Czech republic ( mega). Anyway....I have a magnetic prop balancer, and always like to balance my props as good as poss - how do I balance this folder setup?? Balancer has the "two cones on a shaft idea", and I guess I may be able to fit the whole assembly on the cones whic would be even better 'cos it balances the spinner and back plate at the same time? BUT how do i deal with the blades? I have seen it suggested that the blades be "Jammed " open with bits of balsa / rubber bands and so-on, but surely this will upset the balance process anyway?? It is on an alienator with mega 22/20/3 motor and 4a/h
