One thing about glow is tank size and engine size. I have a revolver and when I had a .45 engine on it I could seriously get about 20 min of flight out of it, I would actually get tired of flying it before it ran out of fuel and when I did land I still have about 1/4 of a tank left. It is hard to compare glow and electric. You can get a higher mah battery and get longer flight time 15-20 min with electrics. I fly gas because I like the sound, but if you are the type of person that likes a nice clean plane and you have to fly where there is a noise issue then go electric.
