I'll see if I can find it. LOL, I'll probably use any free time I have today looking for the link and won't have any time left to do the conversion.

Most of the heli pilots in Asia switch packs so often that a switch wouldn't be of much use and just adds weight (that's what they told me). Anyway, the switch should be able to handle the current for both motors, probably 10amps at 12v would do it.
