What switches?, I just plug my battery in and go flying, Nothing can go wrong except that the battery dies, and I have a tester for it , apart from that a cable might have something funny go wrong, but what's the chance of that. I have already had to rebuild a balsa wood glider that crashed after i bungeed it into the air, the battery shifted and pulled a wire off the switch, and BOOM, 4 pieces to take home.
Anyway, that's my extremely simple solution.Cheers
