I'm using Hitec, which uses the same principles as Futaba - actually it is a
kind of Futaba clone. It should not be too hard to use just that RF module
without the controller, however, I am not sure how the controller tells to
the module to use PCM encodings instead PPM (you can select in between them
using the controller's menu).

Anyway, you can also use the buddy box connector to feed the transmitter
with your input (PPM), the only thing you need to change is that originally
if you release the trainer switch you will get back the control from the
buddy box to the instructor's controller. All you need to do that is to
replace that switch not to do that and then let your original, virtually
untouched controller to do the rest.
