Default Fin Cutting Patterns

Here are the laser patterns for the main fins and the smaller detail fins. The main fins are 3/32" balsa, and the detail fins are 0.05" matteboard.

Unzip this file to get two Corel Draw 10 CDR files.

Exclamation Minor Revisions

Noticed two issues in the first RKT file that need to be corrected:
  • The first centering ring was positioned too far rearward. It should be located just behind the front finlets, or 2.25" from the junction between the two ST-7 tubes.
  • The word "Pterodactyl" was spelled wrong.

No changes in the flight numbers.

Share and Enjoy!
