RE: PLANS TRACING
From experience, it is dificult, then expensive to find a tracing paper of a size to lay a wing or fuselage out on. I ended up with Vellum, an 18" x 5 yds roll for $13 plus tax. For that same amount, you could get the plans copied at one of the copy shops and save yourself a lot of time and maybe some money, and more important, have a set of accurate plans. It is dificult to keep everything from moving when you are tracing, especially on a long wing or fuselage plan. You end up taping to the plan and then maybe damaging the plan when you lift the tape.
If you have them copied, make a 6" ruller on both the X and Y axes on all four corner of the orginal. Tell them you want 100% copies, no more, no less, then measure the rullers on the copies to make sure that is what you received. Also sight down the outline box on the copy to make sure it is straight. Sometimes the orginal will skew a bit going through the copier..
Good luck and let us know how which ever method you use, works out.
