Do what you want to
For my second plane, I built a GP Tracer. In case y'all are wondering, it is a mid wing, aerobatic trainer that really goes where you point it. Many would not recommend this as a second plane, but I wanted it. I built it carefully and with some help. Because I had set up the plane with flaperons, I was not able to use the buddy box. So I had to go from the high drag trainer to the rocket on the first flight. I now have more than 50 flights on this plane, and I have yet to let it get away from me.
So what is my point? Build and fly what you want to...just make sure you get some help. Ask your instructor about the plane you want, and listen to them. Remeber, they are the ones who know your tendencies.
