I was asking my pattern coach about electric, and he figured that with either glow or electric, the cost is about $2.00 per flight. Batteries don't last forever.

I am in the process of making the switch to electric.

This year I tried my hand at a YS engine. I absolutely loved the engine when it ran right; I got used to the immediate throttle response and near instantaneous power. It started to lose interest in 2 strokes for that reason. However this year brought me more engine troubles than flight practice. Add to that the cost of fuel and the fact that I have to drive 4 hours each way to buy it, the mess I've made in my apartment and the oil stains in my car, and the fact that there are really nice fields which are 'electric only' that I have not been able to fly at.

Electric seems to make the most sense for me. Maybe not for others, but there are few, if any, people who convert from electric to glow.
