Would appreciate some advice. I have flown ARTFs for a couple of years but would now like to build from a plan.

This may be a really dumb question but what is the most effective way to cut the pieces I mark out on the sheet balsa ? Use a very sharp scalpel ? Is there a wizard piece of equipment out there that makes the job easier.

No I can't afford a laser cutter.

Any help appreciated.

Also, are there any good sites for getting free or plans for 3D/aerobatic/profile planes for a fair price ?
