RE: Trainer Jet
I vote for a boomerang! i have 89 flights on my Sprint and love the way it flies. There is a learning curve between gas/glow and turbine aircraft. My boomer has helped me get through that curve. It is tough and made of wood so it's easy to repair just like all the airplanes you are used to flying. Check out the Sprint build thread on here. There are lots of pages to go through but no one really has any bad things to say about it.
