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...
Bruce,
good to know about the DSC unit. It sounds like it is a slightly more primitive version of Ace's system. With 2.4 nowadays we don't really need DSC anymore but the method used by the MP8K and MS2K is nice since it allows you to setup servos without a receiver or servo power - it is all driven by the Tx.

I have a Kraft Series 73 7C single stick transmitter which no longer works.
Perfect candidate for an MS2K and 2.4 upgrade. That project would be very similar to the '74 SS in this thread except that you would already have the trim sliders on the side for aux channels. I will be locating the aux channels there too but will use rotary knobs since mine was a 5C and the levers are missing.

The Ace MP8000 single stick transmitter 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]

Great it is indeed. Ace also can provide a shift inverter or, with the latest eeprom, the shift is part of the system like with the MS2K. This allows you to operate it with just about any Rx out there whether it be Futaba, Hitec, Airtronics, JR or Spektrum. Adding 2.4 into the mix would be quite straight forward it would just require a three position selector switch (AM, FM, 2.4) instead of the 2 position which I imagine you have at the moment. For simplicity though, you could consider replacing the AM RF deck for the 2.4 deck and you might not need much in the way of soldering other than the three RF leads to the 2.4 deck. It is likely that the decks are wired with 3 pin deans plugs so if you added a 3 pin deans to the 2.4 module, that would be just about all that's needed. The 2.4 antenna would have to be installed though. The easiest option might be to use a friction fit 2.4 antenna from Horizon which would just go atop the FM antenna housing and would be retained with a wide rubber band over the inside housing. This would make it very quick and easy to replace 2.4 to FM antenna's if you needed - even in the field. Otherwise, the 2.4 antenna could be installed to the side of the FM antenna for permanent mounting.
Converting it to MS2K would be an additional nice
notch above the MP8K encoder but I'd restore the Kraft first if I were you - the MP8K is a great system as it is.
