The dual switches do work great but I don't use them the way you might think. On 50cc and smaller planes I use one battery and one switch that turns on everything, Rx and ignition. Larger planes that use two batteries and a dual switch, each switch turns on one battery, my ignitions are all powered from my Rx. (T.O.M. does not approve of this practice ) There are plenty of people though that do use one switch for the Rx and the other for their ignition.
