RE: 120% Kadet Senior
You know this is a project I have thought of myself once in awhile.
here would be the best way to do it. If you had a kit, you could trace all the precut parts. most of this kit is sticks and ribs, but there are a few pieces up front that are shaped, firewall etc.
I would trace all the precut parts and wire on the back of a set of senior plans, then take that to the copier and tell them you want both sides blown up the same percentage, 120 etc.
They probably can't blow up the front the same size on one sheet because the paper in the big copier isn't wide enough. What you have them do is make a copy of the original, carefully cut them in half length wise, blow up the half plans,then tape the two blown up pieces together.
Also I think you could make many of the out bound ribs from foam to save money.
