Time to unleash another Hydrazine-designed creation upon the public! What is it this time? A fin can, plus a fin marking guide, for the Estes USS Hyperion kit (#1383). It is designed to fit the BT-50 Estes airframe tubing.

There are also 3, 5, and 6-finned versions as well as a version you can print in which you can add your own rings using BT-60, BT-80, and BT-101 Estes airframe tubing.

The nose cone (PNC-50CA) used in the Hyperion kit has been designed and already posted recently.

Both can be downloaded for free and printed on your 3D printer.
Enjoy!
