Well then the 2.4 gig set simply won't work rather than allowing another transmitter to operate the machine. Hardly an issue as there are never more than 3 or 4 machines in the arena during competition fights and the large melees at the end of events etc are for fun anyways. The suprime lack of interference when compared to the old 40meg gear is also incredible. I never worry about having my aerials wrapped up and tucked in behind a fully enclosed metal container.
