Brent,

Definately get into combat. It's a blast. Dave Davis answers "why should I try combat?" [link=http://www.treneffrc.com/featured%20pilot%20-%20dave%20davis.asp]here.[/link]

I would not suggest combat with trainers. The airplanes can't handle mid-airs and .46s will cut up the radio gear and worsen the situation when you do have a midair.

Get some type of dedicated combat plane. I'm sure you don't want to wreck your trainer.

When you try combat, you'll be hooked.
