Well since someone else brought up "that" topic... I've always mounted my switches externally (with "on" toward the tail so it is unlikely to be bumped to "off", and on the opposite side of the fuse from the exhaust) but I've noticed just about every ARF I've seen has an internal mount for a wire operated switch. So, other than less intrusion on appearance what's the benefit of an internal switch? Does the operating wire vibrate and wear the hole in the fuse larger? What else should I know about internal switches that I haven't thought of to ask?
