RE: Okay, who's the Kraft radio guru?
I have the attached drawing of a trainer cord for Kraft. I mde a cord about 14 years ago connecting a bicentennial to a series 79. I think I used this drawing and regular din conectors. I hope this helps, oh though you may not be able to connect different transmitters if they transmit the control channels in diffrent order. If anything you could use it to attach kraft to a flight simulator.
One other thin not all din plugs label their pins in the same order, so use the diagram for location.
