You need a pretty big hall to get a plane up to 60mph, and to control it there. Indoor aerobatics can be pretty awsome, though, in a way that is very different from the feeling that you need to duck behind a car when a F3D pylon racer is in the air....

There seems to be a thread on electric vs glow pros and cons here:

At least some of the posts are to the point...

One group of things that affected my choice when I started has not been mentioned yet.

- Do you have the space to build, store and transport a "largish" plane?
- Do you have a club with a good field within reach?
- What sort of weather do you have in your area, especially wind conditions?
- Do you live with someone who might object to you taking a smelly plane into your home? (I like that smell but ...)
