Skybound,
I would invest in the Great Planes Simulator along with a high wing trainer. You might check you local hobby shop for maybe a used trainer setup sometimes you can find a good deal on a used airplane also. The Dragon Lady is a good airplane to fly as a third/second airplane. She handles very well at low speeds and such. You could always use the radio pack out of either the cermark or the dragon lady and use it in the trainer. A .46 sized engine will not cost you much compard to wrecking either one of the birds you are buying.
