Electric or glow? The choice is yours. If you want to fly in parks, electric is the way to go. If there's a nearby club, go with what they are flying, be it electric or glow. Personally, I like glow, but electric has a lot going for it too.

I'm not crazy about RTF units. They usually contain mediocre components that are of limited value for subsequent planes. I only suggest them for people who are not interested in doing the legwork to choose the components. You can build complete packages with a .40 size ARF, a decent .45 engine, and a 4 channel radio that are the same, or even less, money as an RTF package. If money is not tight, consider choosing a 6 channel computer radio instead of the 4 channel. If money is no object, go for a 7 or even 9 channel radio. One plane I suggest is the Tower Trainer ARF. My reasoning is it's not expensive and it flies well. There's no reason to spend a huge amount of money on a trainer, they are all designed to be slow and stable, and they usually get beat up. Better to save the money for the second, third, etc plane.
