CG is right on, honest and unbiased facts. Alot of us do both, both have advantages and disadvantages. Don't let anyone tell you electric is cheaper, you pay for what you get, better performance from glow or electirc means buying better equiptment. With glow if you want to fly several times in a row, land fuel it up and test the receiver battery and take off. Electric, land change the battery and put first one on charge and take off. Flight times are ussually longer with glow, with electric there is always less clean up!
