For other models of Dynamic controls it could well be CAN Bus.

What do you mean by this? The Shark and DX (or DX2) are different systems though both use the DX bus cable. I no longer have a DX system active here, so can't check voltages and waveforms. Have you checked this on an actual DX system?

There will be a sticker on it, it may also be able to be identified by a picture of your joystick.
If you could post pictures of both it would help us give some clear answers.

it is CAN, though a restricted version limited to a max of 125kbps, with 3 rather than 4 data bytes per frame

The correction is that the standard CAN frame contains 8 bytes of data, not 4. I have 4 in my head because in my system I send (up to) 4 bytes of data and (up to) 4 bytes with the the bitwise complements of the data bytes so that the receiving node can make an extra check (beyond those provided by the CAN protocol itself) for the validity of the incoming information. (This is similar to what's done in the "safety critical" flavors of CANOpen.)

If i get a BUS extending block and an attendant control and then hack into the second control stick and using that secondary control as the R/C input as at moment all I want to achieve is motion of chair
