# TerraHawk, public
|
|
|
|
This is the public side of one builder's TerraHawk FPV: a 3D-printed 4+1 quadplane (the
|
|
Nomadium Robotics kit) flying ArduPilot, with a mapping camera in its belly and an outdoor
|
|
charging dock. The build log and reference live at https://terrahawk.warehack.ing.
|
|
|
|
This repository carries two things:
|
|
|
|
- **Releases.** This build's own work as files you can use: our printable parts, the parameter
|
|
files, print jobs and firmware.
|
|
- **Payload briefs.** Ideas for what else could ride in the belly bay, filed as issues.
|
|
|
|
## What is never here
|
|
|
|
The kit's STL files, and parts made from them in full, belong to Nomadium and are not
|
|
published here or on the site. Get the kit from Nomadium:

|
## The payload bay
|
|
|
|
The bay is in the belly, behind the battery, and the payload is its cover: nine M3 x 8
|
|
countersunk screws hold a cover to heat-set inserts, and whatever is on that cover is the
|
|
underside of the aircraft. The first payload is a MAPIR Survey3W mapping camera. The limits,
|
|
estimated on 2026-10-02:
|
|
|
|
| Limit | Value | Note |
|
|
| --- | --- | --- |
|
|
| Mass, trimmed with the payload aboard | up to about 185 g | The CG stays inside its envelope after a drop |
|
|
| Mass, trimmed empty | up to about 273 g | The CG stays inside its envelope when loaded |
|
|
| Drag, cover fitted | none | A flush cover costs nothing |
|
|
| Drops | need the cargo door | The door is not on the first build |
|
|
|
|
These are estimates. The [payload ideas](https://terrahawk.warehack.ing/explanation/payload-ideas/)
|
|
page explains them, with twelve candidates and what each would cost.
|
|
|
|
## Propose a payload
|
|
|
|
Open an issue with the **Payload brief** template. Estimates are fine: say what you know. The
|
|
fields are the ones the aircraft and its simulator need (mass, size, power, interface, the
|
|
mission it flies, and whether it drops), so a brief filed today is not asked for again.
|
|
|
|
Opening an issue needs an account on this server, and registration is closed for now. A public
|
|
form on the site is planned.
