There is a separate Kraft contol box for directly controling the servos and I have one. It is like a servo tester in its operation and needs to be plugged directly into the servo. I have a Kraft Series 73 7C single stick transmitter which no longer works. And I have a Kraft Bicentennial Series '76 single stick system which is gold stickered and runs great. I have both AM and FM rf decks for it. I also had it updated in the '80s with servo reversing and ATV. The Ace MP8000 single stick tranmitter I still use is great and it currently has switch selectable AM and FM modules. I have been thinking of updateing that to Futaba Fasst via Radio South since I currently have Futaba 7C and 8FG Fasst systems. I have also been thinking of converting it to the MS2000 encoder board. I use to do all of my own radio work back in the '70s and '80s but no longer have the steady hand necessary for soldering. Therefore I would need someone to do the updating for me.[&o]
