One other note on safety. Electrics pose a couple of important safety issues. First, it's possible to accidentally start an electric engine. Perhaps the throttle on the transmitter gets bumped and you don't notice, then you turn the planes switch on, and zoom, there goes the plane. With a glow engine, the engine will not start until you intentionally start it. Second, if you get your hand into the prop, a glow engine will often stop. It's even possible to throw a rag into the prop to stop a glow engine in an emergency. With an electric motor, the prop will keep spinning as long as the motor has the power to turn. Once you start getting into larger electric motors, these can have serious results.
