The company that I work for sponsors multiple local TARC teams. Normally, in October we host a non-official TARC regional challenge, except this year the committee proposed that we do a “virtual flight challenge.” They came up with a preliminary plan that I summarized below. I thought that it...

I have been wanting to make this type of fin for many years. I have done some experimenting along the way, but never completed a whole set. Now that I have a 3D printer, I decided to use it to make a mold. Nike fins for 4” tube seemed like a nice size and design to start with. So far, I have...

Simple assembly/gluing jig for attaching centering rings to motor mount tubes. Works perfectly with 24mm & 29mm tubes, and BT-80 centering rings. It comes with regular binder clips to clamp the CR to the fixture. This jig will also work with other sizes of centering rings, but may require...

Flat, 3D printed fin jig for 1/8” fins, and up to 4” diameter tubes. I have been using this basic design for decades and it has always served me well. The slot on this print is .135” wide. A little bit of masking tape (see photo) will reduce it down if your stock is thinner. I can also tweak the...

I have a Formbot Raptor, does anyone else have this, or a Vivedino Raptor 2? I purchased my Raptor in December of 2018 from Tiny Machines. It is a pretty good machine, but a big drawback was the lack of a good user base, so this is my attempt to get some info out there. I learned about...

I bought my first roll of PETG, and I'm wondering how you get paint to stick to it. I have painted PLA, and that works great, but PETG seems much slipperier.

One piece Fin-Can designed for LOC BT-3.90 tube. It is made using carbon fiber-infused PLA filament and a Formbot Raptor printer. Features four diamond airfoil cross section fins with large ½” radii at the root. The fins are about ½” thick at their widest, and the can about ¼” at its widest...

Does anyone have a RockSim/OpenRocket file for an Ultimate Wildman Kit to share?

Aerotech Initiator Rocket, flown less than a dozen times. Includes an 18” chute. It looks, works and flies nice, but there are a few minor issues: 1. The motor hook is positioned to accept single-use motors with ¾” masking tape wrapped around them. 2. A small hole was repaired near the aft end...

This was built for my rear-ejection Thundercloud rocket, and it always worked very well. I think it would work equally well in a rocket that uses a release mechanism such as the AARD to let the drogue and main out the same tube. I say this because it is set up to fasten between two body tubes...
