Brawny

With a paper towel roll, you can build a Brawny. Components are 3D-printed, except for the tube, 2 small screws, and the recovery device. This rocket can be assembled without glue, meaning it is ready to fly as soon as you finish building. NEW: Brawny V2 adopts the Zip-Fin system for easier assembly. 2 small zip ties are required to attach fins. 3-D printed launch lugs are also included, which can be easily glued on using superglue (CA).

3D printing settings (ABS, PETG): 0.4mm nozzle, 3 perimeter walls, 2 top & bottom layers, honeycomb infill (15%), no supports.

Zippy

Zippy is the big sibling of Brawny. Instead of a paper towel roll, it uses a potato chip can (from Pringles or your favorite other brand) as the body tube of the rocket. This stubby rocket flies to a relatively low 600' altitude on "D" engines and is easy to spot in the sky, making it a great park rocket.  The Zip-Fin system makes assembly easy. 2 zip ties are used to secure the fins.

3D printing settings (ABS, PETG): 0.4mm nozzle, 3 perimeter walls, 2 top & bottom layers, honeycomb infill (15%), no supports.

Toucan

An advanced evolution of Zippy, the Toucan is even bigger and uses two cans! It can reach 600' altitude on "E" engines and is capable of using "F" engines for even more performance. Optionally, Toucan can be built with an integrated ejection baffle.  Download the parts package for Zippy, then add the parts below for Toucan.  Additional parts include a tube coupler, ejection baffle, and longer motor mount for 95mm motors. You provide a length of BT-20 tubing. Also download the fin STL (2nd file). If you wish to fly from a 1010 rail, you can download glue-on rail guides which are sized for Pringles tubes.

FreeBird

The FreeBird's 3D-printed fin can makes the hard work of cutting, sanding, and aligning rocket fins much easier. Other components of the rocket are conventional in design, making this comparable to other Skill Level 1 kit rockets. Superglue or plastic cement is used to glue to the fin can to the body tube. Painting is minimal and easy.

FreeBird X2

Take a FreeBird, make it longer, and add a booster stage, and you have a FreeBird X2 two-stager. This is a high-performance rocket capable of out-of-sight flights to 1200' or more.

Display Stands

Display your rockets using these handy 3D-printed display stands. Print without any supports; a raft is recommended. Sized for 18mm (A/B/C motors) but can easily be scaled up for 24mm or 29mm motor tubes as well.
