The RC needs to detect power from the 12v terminals before it will start up.
After the 12v is disconnected the Master code turns off the RC running on backup alone after a few seconds. Of course there isn't enough power to do more than drive servos.

If it's not for competition there is a way to get the RC to run for about 3 minutes without 12v power using the 2004 version of the Master code, but it still needs a goose to start (we sometimes use a regular 9v battery to jump start it).
