There are literally hundreds of well-established designs with all the kinks worked out already. I very much appreciate your desire to learn about models and flying that is easy to see in this and your other posts. But good aircraft designers don't start out by dreaming up their own designs at the beginning. They start by learning what has worked before and why. Then they start using that creative spark to improve upon existing designs or apply that knowledge to new problems. So, as you've been advised before, start by building a few of the tried and true designs instead of trying to come up with your own thing as a first attempt.
