PX4 X500
The PX4 ecosystem's reference quadcopter kit: a 500 mm X-frame, four 2216 920KV motors, a power-distribution board and a Pixhawk flight controller. RobotForge flies this exact airframe as the PX4 Gazebo model (x500), so its geometry here is read straight out of the model's own files.
Spec
| Battery | 4S LiPo 14.8 V, 5000 mAh (Holybro recommends 3000–5000 mAh) |
|---|---|
| Flight controller | Pixhawk, powered via PM02 power module |
| Frame | X500 quadcopter frame, 500 mm wheelbase class (Holybro) |
| Mass | 2.064 kg — sum of the Gazebo model's link masses (base_link 2.0 kg + 4 rotors) |
| Motor-to-motor | 0.348 × 0.348 m (0.492 m diagonal) — rotor positions in the PX4 Gazebo model |
| Motors | 4× 2216 920KV brushless, BLHeli S 20A ESCs (Holybro kit) |
| Power | Power-distribution board documented: XT60 in, XT30 out |
| Propellers | 0.279 m in the Gazebo model (the physical kit ships 1045 props) |
examples/px4-x500.jsonGeometry, height and link masses from the PX4 Gazebo model x500_base/model.sdf (rotor poses ±0.174 m, base_link pose z 0.24 m, link masses 2.0 kg + 4× 0.0160769 kg). Kit hardware (motors, ESCs, PDB wiring pattern, battery recommendation) from Holybro's official X500 V2 product page. The Gazebo model's propeller (0.279 m) differs from the physical kit's 1045 props; the model's value is what the spec carries, and the difference is stated in the key specs.Imported specimen

An import is provenance, not a verdict: this entry stays Not gated, and no parts kit is defined for it.
GateA pass/fail test in the Gazebo simulator: the twin drives 1 m, turns 90° and stops, and the result is measured against where it really went. runs
The motion gate covers ground robots today. This class has no gate yet, so there is no verdict to show — the note below says why, in the entry's own words.
No recorded gate runs yet. This robot has no verdict until one is measured.
HarnessThe robot’s wiring. The harness check adds up current on each power rail and flags wires that are too thin or rails that are overloaded. checks
Electrical checks over this robot's documented wiring. Not a simulation; the headline is counts, never a blanket pass.

Check-by-check counts and missing data
| Check | Checked | Partial | Not checked |
|---|---|---|---|
| voltage drop | 0 | 0 | 4 |
| ampacity | 0 | 0 | 4 |

Findings: none — the inputs that could be checked raised nothing. That is not the same as everything being checked; the counts above say how much was.
Missing data — the datasheets still to hunt. A check that could not run says what it needs:
| Missing input | Blocks | Needed by |
|---|---|---|
cable.gauge_awg | 8 | battery -> pdb, pdb -> esc, esc -> motors, pdb -> fc |
current_a for motors | 7 | battery -> pdb, pdb -> esc, esc -> motors, esc rail |
current_a for fc | 5 | battery -> pdb, pdb -> fc, pdb rail |
cable.length_mm | 3 | battery -> pdb, pdb -> esc, esc -> motors |
connector at both ends (connector_from / connector_to) | 3 | esc -> motors, pdb -> fc, fc -> esc |

Take it apart
This viewer derives a schematic take-apart straight from the spec's numbers — the same one-derivation rule as the ground kits — flat views, or in 3D with the toggle. It is a schematic of the real robot's layout, not a printable kit: robotforge cad kits cover ground robots only today. Click any part.
examples/px4-x500.json…Parts kit
The take-apart kit robotforge cad generates from this robot's spec: every part the generator defines, what it does, and the parameters worth tweaking with the values this robot's kit ships with. Each parameter carries the generator's own source label — from spec numbers come out of the spec, derived numbers are computed from them, and assumption numbers are typical values the spec does not carry.
No take-apart kit is defined for this robot yet — the kit generator builds kits for wheeled ground robots from the spec's wheel block, and this spec has no wheels.
Reproduce it
Run these from a clone of the repository. The twin, CAD kit and motion gate (urdf / cad / run-gate) cover ground robots today, so they are not listed here.
