Vetical; thanks for the input; my radio is a Futaba 7 ch 72MZ and does not accept a module, nor does any other of my radios from the past 37 years. I will give the straw trick with some web paper splicing tape on it.
So ditch the old Futaba gear and get a new radio. All your servos, switches, and batteries will still be good, you just need a new TX and RX, be it Spektrum, JR, or Futaba FAAST. I was hesitant to make the switch too, but in retrospect it was the best investment I ever made in the hobby.
