That's not true for the 2004-2008 controllers and I don't see how it could be true for the 2002 controller (it isn't true for mine but the Master Code might have changed since 2002).

When the RC loses power, the speed controllers and spikes stop receiving a PWM signal that allows them to move. They immediately go to the no signal state and stop until the RC finishes rebooting and reevaluates the joystick inputs when it comes back up (~ 5-10 seconds).

What is your speculation on the technical reasons why you had that problem in 2002?
