The is repo will contain all the build, scripts and params needed to build your own Lynchpin drone.
These are all the components you will need, this is not a exhaustive list, general consumables are not included (such as zip ties and heat shrink). For the most part similar alternatives can be used but motors and props should exactly match for the Lynchpin PIDs and mixer to be used. Likewise a drone of identical layout but different scale will need a new mixer.

- ESP8266 - Adafruit Huzzah
- Carbon Tube 4x - 10mm OD, 9mm ID, 1m, to be cut into lengths of:
- 4x 100mm
- 18x 115mm
- 6x 182mm
For best results load Frame.3mf for pre-setup supports and layout.
Structural components are printed in PTEG with 5 perimeters and 15% infill. See above image for ideal layout and part orientations. Some parts require supports this should be from the build plate only and have a maximum Z height blocker such that supports are not added to the internal holes.
- Bottom Node x 3 - requires support
- Top Node - requires support
- Center Node - requires support
- Corner Node x 12
- Motor Mount x 6
Optional, but very useful, tube cutting guides can be printed from any material with standard settings.
The base plate is designed for laser cutting, any material of about 3mm thickness, Acriylic looks cool. Alternatively the plate can be printed.

Close up pictures:
ArduPilot setup is much like a normal copter. Param set here. You will also need a lua script to tell AP the location and directions of each motor. Optionally an additional script can be added to give control over the roll and pitch axis.
