Yup.. I've done exactly what you did on all my Rc's since the laste 90's but I go extreme overkill on the wire size.. Its all Deans wet noodle (12 or 14ga I believe) wire. Plus since I have Deans Ultra plugs on all my chargers already its super easy to charge my RX packs. I've Never had a single problem with this setup in all these years and I don't expect to! Switches go bad randomly or can cause glitching because dirt gets in there and causes the switch to loose contact as the engine vibrates.
