Got a lot of good help with the information I needed to make good scale design. As I went through it all I realized the it would be so easy to provide the design for the 200, 250, 300 and 350 as they are all based on the same airframe, just adding length to the fuselage and nacelles in all cases, and in the case of the 350 some more nose. The 90 will take a little more effort as the whole tail is different so it would be last if I do it. So I am busy working on the line drawings for the base; the 200, then will modify it to get the 350. Later doing the other versions; 250 and 300!.
