The tips here are really good, esp the one about not flying a warbird as your first low wing. If you want a cheap but fun first low wing tail dragger then get a world models skyraider Mk2 at something like 70 bucks they are cheap and most likely will run on the setup on your trainer. They are easy to fly and a good first tail dragger and low wing. The again I have been flying my spitfire since only 4 months of solo and doing it well, so you may be able to fly it, then it depends on what the guys at your club think.
