Hello I have a pair of the Older Futaba FG Gold Box TX systems , I want to use one as a buddy box and would like to find a Plastic TX Module to plug into the buddy box unit , doesn't matter if it's AM , FM or anything , I really only need the Plastic case as a protective Dummy but if the circuit board was still in that would be better as I do have to pick up two of the pins for the volt meter. Thanks Phil Lohiser
