The Mid Star is a much better second plane than the 4 Stars. In fact Bruce Tharpe designed both and back in the day the Mid Star was marketed as a 2nd plane and the 4 Star as a third. The Mid Star will land almost as slowly as a trainer and it is really easy and quick to build. Plus it's a great aerobatic trainer. I don't know what peculiarities there are to be worried about with it, just build it the way it says in the manual, no modifications are needed, and you will have an excellent second plane. If you build it with conventional gear it will be even lighter and more nimble for you. If you like the looks of the Mid Star do not be dissuaded from getting it. It is a great second plane. In fact if you can solo a high wing trainer you will not need any assistance to fly the Mid Star, well if your nervous you might have someone 1st flight it for you, but otherwise you will find it a great learning tool.
