Final URCA Quadcopter Design

Here you can see the full assembly file, as also displayed on the main project page. Below is the bill of materials if you are interested in the more technical details.

As stated on the main project page (see my portfolio page), the design is meant to be as compact as possible while still supporting the payload. This is because the quad is meant to be flown indoors and in tight spaces. The frame is actually 5 different parts, each arm connected to the main body by two bolts, this way if one were to break it could be replaced without changing out the entire frame. It is also designed to be flat machined so it could be made easily out of many different materials, but ideally fiberglass or carbon fiber for its high rigidity and low weight.

The model was created, rendered, and animated in Fusion360. I have since migrated to SolidWorks but still hold great appreciation for its abilities.
