    Cox Apache CL Helicopter "Heavy Hub"

    Managed to misplace the "heavy hub" (prop nut/balancing weight) for a Cox Apache helicopter. Anyone have a spare or know what they used?

    TIA!

    Maybe you can find one of the Harry Higley Heavy Hubs for Cox engines. Your local hobby shop, if there is one, might have it.

    Thanks Jim. The Higley Heavy Hubs are for .20 and larger engines according to their catalog, and don't go as small as the Cox shafts ... I wonder id Du-Bro sold this or a similar hub at some point?

    I have a couple of the Higley 049 heavy hubs. I'll see if I can find them in my 1/2A stuff.

    I have found one. If I can find the other one you can have it. The heavy hub is a piece of (I think, did not test with magnet) plated 1/2 inch brass hex stock. The front end is rounded, and a 5-40 setscrew is inserted in the flat back, for screwing into the crank. It weighs 1/2 oz.

    Another old school solution that can be done is to remove the Sure Start .049 spring starter assembly and wrap lead solder (used in electrical work and plumbing) around the front shaft of the crankcase.
