Well if you have a choke on it then you would be fine with the switch but other wise the gas engine is different than glow because the glow will shutdown if you close the throttle all the way where as the gas engine will keep running till it runs out of fuel so if you are flying with glow you can hit the throttle kill if you set it up and also that glow engine will be out of fuel in about 15 minutes. The gas engine on the other hand will run for 30 minutes or so on a tank so if you have no way of shutting down well you will be flying along time till you run out !!!
