The headset that comes with the CIA set looks great - the boommike and pressel switch look perfect. So I though I'll stick that on my D-boy. So I chopped it up, so now it rests close to my guy's head, and then attached it to part of Raptor's radio arial. Just by carefully bending the end of the arial, you can secure the headpiece quite easily. At the other end I did the same with a small rectangular piece of plastic...
voila!
