A good flatbed scanner can copy parts of the plan to make cutting templates. I temporarily glue the template on the balsa using a very light misting of 3M 77 spray adhesive and then cut out the parts with a scroll saw or disk sander. Then the paper can be pulled off. If you have a laser printer or Xerox copier, you can put the print face down on the wood, wet the back of the paper with acetone, and the print will transfer directly to the wood.

Your first plan built project should be something simple, for example, Randy Randolf's "Bee Tween". Don't be afraid to change things, it's not like the sky will fall if the plan isn't followed exactly. I frequently make minor design changes, for example, aluminum landing gear instead of wire or electric instead of glow.
