If you go with am FM tx/rcvr (like 3PM) its just a matter of unplugging your old recvr, removing same, mounting the new rcvr, running the new antenna, then plugging everything back in correctly, steering, th/brake and battery. Then setting end points to limit steering travel and th/brake travel too. That will require a little reading in the manual to find out how to make the adjustments.

If you go with a FAAST setup (like 3PM-X), still pretty much the same except you have to bind the rcvr and the tx together which takes all of a few minutes.
