So if an M4 is wired to the back, there are 2 wires right? (One positive, and one negative.) Well you can disconnect these wires to get to the gearbox, right? Well... In an Echo-1 you can't! These bastards did a fine job of soldering the negative wiring 'connection points' completely together. So I had to just yank the whole thing apart to get to my gearbox, and now I'm screwed because I am unable to get the negative wires to connect.
Could I perhaps re-wire and use a different style of connection? Like some off an old set of Tamiyas?
