Just a little bit about plans. When you have plans from kits they are building plans and do not show any of the ribs or formers, they don't need to, the parts are already cut for you and in the box. Building plans show every part you will need and you cut them out then use them as templates to cut your parts. If you buy these plans from someone like MOdel Airplane News you will also get a copy of the build artical that was published in the magazine. Some help but not a lot.
Some of the free plans you get off the net are just old kit plans and don't do a new builder any good. Got take a look at the plans from the AMA or MAN, these are building plans so you can cut your own kit then build the plane.
