I would suggest you start with a Mark IX source file and create a late Mark IX/XVI.  Late production IXs had the cut down rear fuselage and buble top, broad chord pointed fin/rudder.

By starting with an existing source file,  you can modify the fuselage, etc., and add details, while not having to worry about the wings, gear, etc.

Remember - I started with FSDS 1 - early version.

Not counting the tutorial, My first release was a Mig15... and it was my first real attempt at completing a plane, rather than testing the program.

I really spend most of my time playing with the programs rather than serious attempts/

Also, remember that the "quality" at that time - (has it been three years already?) - wasn't as good as today's demands.

My first "real" project took about three weeks - of non-continuous work.
