The plans call for installing an SB187-2 snap bushing where the wires from the control head egress the lower end of the control stick. The teen group I'm working with is having a good deal of difficulty fitting this bushing over the wires (and presumably I will as well in a few days), so I'm wondering if anyone has a favorite trick for getting all the wires through that bushing without causing any damage. I've found notes that it can be difficult, but I haven't found mention of what eventually led to success. I'm thinking it may be necessary to slit the bushing, but that's treacherous on such a tiny part. Does anyone have better advice?
