That's a very good point. I first heard of this method about 8 years
ago when hand launched RC gliders were becoming popular - the phono
jack is lighter than the standard switch. I haven't heard of it being
used on power models. A point to watch is that with the plug removed
the jack is an open hole - great for getting gunge into the contacts!
