Description
INTRODUCTION
This is team “Jet Research”. We are happy to present our first aircraft design - the Jet Research High-Performance Glider. We are a group of students from Embry-Riddle Aeronautical University, Prescott, and we are highly enthusiastic about 3D printing technology. With this project, we have pushed our understanding of 3D printing to the limit, and we would like to apply what we've learned to our future project - a fully 3D-printed turbine-powered RC aircraft!

Happy New Year Everyone!
There was a mistake in the CG location. The correct CG location is 5.5 CM from the leading edge as shown in the picture below.
Also, I almost have my next two airplane designs ready to upload. Stay tuned for my new larger airplanes!

Now, you can watch a full-flying video of our glider on YouTube!

Update 11/01/2024
As requested, here are some instructions on installing the elevator, rudder, and torque springs.
Here's a closer look at the tail assembly, the control horns are store-bought and cut to the length needed. The block that guides the fishing wire to the rudder is optional. Holes are simply cut to the arrow shaft with a drill bit. Make sure you take your time doing this because it is not easy.
The picture below shows the position of the rudder torque spring in red color. I use 0.5mm music wire or spring steel wire as the torque spring. The length of the rudder torque spring is 10 cm.
The picture below shows the position of the elevator torque spring in red color. There are two springs for the elevator. Each spring has a length of 8 cm.
Hopefully this helps!

GLIDER DESCRIPTIONS
This glider targets RC pilots with experience with RC gliders, especially DLG gliders. Some building techniques you will see throughout this project can be commonly found in DLG designs. This glider is not easy to build, therefore please follow the reference document to guide yourself throughout the building process.
The Jet Research Glider is mostly printed of Bambulab ASA Aero (printed as light as possible). Some of the key components are printed out of Bambulab PAHT-CF or PA-GF. All moving hinges are printed with TPU 95A (2 layers of 0.1mm thick). Some carbon tubes are required to enhance the structural integrity of the glider. The tail boom is simply a store-bought standard .244 in arrow shaft. These manufacturing methods allowed us to build the glider as light as possible.
