Default Cutting Patterns

Here's a set of templates for the wings, vertical fins, and the three pylons. I'm supplying both a JPG and a CDR file (for those of you with Corel Draw 12 or better). The fins are cut from 3/32" sheet balsa.

Keep in mind the tube pylons are not solid balsa blobs, but rather are hollow gas passages. My design calls out balsa (a RS limitation), but actually uses 3/16" launch lugs as the central structure, with 0.02" matteboard skins and square balsa strips for the leading and trailing edges.

The nose cone for the rear pod should be hollowed out, and the lugs from the rear pylons should extend through the balsa to the opening.
