RE: Sites for gas setup advice.
wyo you are absolutely correct in that the Ultra does not need a switch. I use one because my Futaba radio has a servo test function that I use. During that function it cycles all channels hence my extra switch so the ignition is not cycled on and off. Else wise one is not needed. Good catch. And I as well do not remove my battery for charging. I made an adapter for the balance plug to run through a typical switch charge port.
