Oh Dr1 i just saw your reply in the aerodynamics section and thought of asking you here instead of posting a new thread for somethink this simple. I bought this little Flying boat i told you before in my post. This comes in pieces. I do have a friend who is working in a wood workshop or i don know the exact word in english. Anw so what if i multiply my pieces x2 and cut them in exact analogical shape to get a double sized boat. Do you think it will work? And generally on a plane if you multiply all the pieces with the same number will the C.G change and have stability problems? Thnx again
