I'm assuming that the R/C transmitter is modulating two channels on either
27Mhz or 49Mhz...it is probably a non-digital-proportional servo system, so it
is forward or reverse on channel A and left or right on channel B to the servo
units. I don't see how a transmitter could be effectively harnessed, but I'm
not saying it couldn't.
I was looking at a relay-type system to select between motors on the A/C
outputs.
