Don't worry about it...when I was 15 I used to draw up full scale plans for ducted fans for hours and hours, and talk about it to whoever would pretend to listen. I am just glad to see some young people that have enough interest to at least research the subject. Some of you guys might want to think about that.

Well I stopped on and off over the years, but I just got my 2 P-160s for my new project. Never give up.
