TOM, I figured I was over analyzing the situation. Thanks for the help. It is probably alot easier to setup then what I am thinking it is. The A123 battery plugs into my reciever just as the standard battery does and powers the reciever and servos just as normal. Why do they come with two leads? What would be the differance between pluging in one lead or two? I need to leave one reciever slot open for smoke. Is this going to be a strain on the circuits of the 617 reciever, in other words can this reciever handle the amperage demands of the higher torque servos?
