# ARK RIG7
The ARK RIG7 is a 7 inch quadcopter reference design for developing on ARK electronics, built around the ARK Jetson PAB Carrier. ARK does not sell the frame or a kit. Cut the two carbon fiber plates from the design files, print the plastic parts and add the parts listed below.
## Frame
| Files | Contents |
| ---------------------------------------------------------------------------------------------------------------------------- | ------------------------------------- |
| [Fusion 360 design](https://a360.co/4703jjy) | Top and bottom frame plates |
| [ARK\_RIG7/printed\_parts in ark-hardware](https://github.com/ARK-Electronics/ark-hardware/tree/main/ARK_RIG7/printed_parts) | Landing gear and prop guard STL files |
Cut both plates from 3 to 4 mm carbon fiber sheet. 3 mm is lighter and flexes slightly. 4 mm is stiffer and heavier. ARK has had good results with [CNC Madness](https://cncmadness.com/) for cutting.
The front of the frame is the end with the optical flow sensor cutout. The geometric center is where the two motor diagonals cross, between the two hex cutouts in the middle of the bottom plate.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.arkelectron.com/products/airframes/ark-rig7.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
