If I did not have boxes of glow and diesel engines, I would be very interested in electric. If I were just getting into model aviation, I would go electric without question. There are big bucks being put into development of small powerful electric motors, and small, light, cheap, safe, sources of electricity. At some point in the future electric will out preform IC in all sizes. Ten years from now, you are going to have a very limited selection of IC engines, if any. And the IC engines available 10 years from now will be very similar to those available today.

Your Model Aviation editor, Bob Hunt, made it onto the USA CL Precision Aerobatics Team to compete at the World Champs next year. He did so with a 40-size airplane converted to electric, flying against up to 75 size glow engines. I understand that competitive RC pattern fliers are going over to electric. Costs, I think, are still high, but that will change.
