Printed some tissue :
and did the fuselage and horizontal stab in Depron (the wing shown is a b+w paper mock up to check size):
Also used the 3 view to cut formers for the front of the fuselage and the cockpit area - they will set the transition from the round fuselage front to square behind the cockpit.
As shown in the attachments below, I bevel all edges to be joined, and then apply pastel chalk to the bevels, matching the colors on the tissue. That process ensures that white Depron wont be showing where the parts are mated.
