# MD500 Civilian

> Lightweight 4-seat open-air utility helicopter. Fast startup, nimble handling, 4 colour variants.

The MD500 Civilian is a lightweight, open-air helicopter. With no enclosed cabin, both cockpit and rear seats are fully exposed to the elements. It is one of the faster-spooling aircraft in the mod and handles with a light, responsive feel.

## Variants

| Classname                            | Livery                          |
| ------------------------------------ | ------------------------------- |
| `CZ_MD500_Civilian`                  | Civilian white                  |
| `CZ_MD500_Civilian_ClassicRedSilver` | Classic red/silver retro livery |
| `CZ_MD500_Civilian_BlueCharter`      | Blue charter / tour company     |
| `CZ_MD500_Civilian_GreenTour`        | Green eco-tour / ranger         |

## Doors

The MD500 has 4 removable door panels — one per seat position. Removing a door makes that seat accessible and leaves a physical door item that can be picked up or left behind.

| Door Item Classname         | Position               |
| --------------------------- | ---------------------- |
| `CZ_MD500_Civilian_Pilot`   | Front left (pilot)     |
| `CZ_MD500_Civilian_CoPilot` | Front right (co-pilot) |
| `CZ_MD500_Civilian_Cargo1`  | Rear left              |
| `CZ_MD500_Civilian_Cargo2`  | Rear right             |

Each variant has its own door classnames (e.g. `CZ_MD500_Civilian_ClassicRedSilver_Pilot`) — add these to your `types.xml` if you want doors to spawn with the helicopter.

  These are indicative dev-tuned defaults and can change between builds — the in-game **Admin Panel** always shows the live per-helicopter values.
