This is how i run mine
I dont run a switch. I just use micro deans plugs between the receiver and battery box and unplug them to turn it off.
I put my regulator where the switch was. I use a KingPower 5A reg with a Thunder Tiger 1015 and a Sanwa/Airtronics ERG-VZ
I also use a bit of airbrush hose on the end of a 10mm peice of antenna tube and curve it back onto a long grub screw. it makes it so much easier to get the body on and off in a hurry. And it looks great without the antenna sticking out. it doesn't loose signal until well past 100m
