I don't have one but I know several people who do. It's a nice trainer. Building it is about like putting an Airfix kit together. It's worth putting a .46 in because they're fairly heavy but they always fly well and are pretty resistant to damage.

The things that do break are the main landing gear legs and sometimes the aileron control horns (if the wing twists in a real crunch). They are readily available as spares. It's also worth getting a spare wing bolt or two. They're easy to lose and they're a really odd size that you'll never get hold of other than as an official spare part.
