Next up, you need to make yourself a pattern to guide the router. This step allows you to mill out airframe parts quickly and with good repeatability. It takes what can be job which fills an hour or more, and turns it into a 10 minute job with very repeatable results - especially important if you plan to build more than one of the same foamy.

I like to use 6mm depron as a guide. Its relatively cheap and pretty strong. As an alternative, you could use 1/4" balsa as well.

I start by laying my cut out part on the depron and tracing around it with a ball point pen. Take a moment to mark the hingelines, bracing points or anything else important on the 6mm depron.

Once you have your parts traced on the 6mm depron, you can begin to draw in the 'structure' that will remain once you've milled the parts. There are varying ways to do this, however, triangles are always strong design elements.

Do yourself a favor and use a straight edge to draw in the lines. Doing a sloppy job here will result in a sloppy milling job every time you use this milling pattern.

I like to leave the root of horizontal stabs, as well as the nose and landing gear areas on the fuse unmilled.
