# types.xml, events.xml & traders
> Ready-made types.xml, events.xml, cfgeventspawns.xml and pre-priced trader files (TraderPlus, Dr Jones, Expansion Market) for every CZ Autoz helicopter — all 19 spawnable classnames plus all 60 doors, 6 wheels, and the battery / repair kit / fuel drum items.
Copy the entries below and merge them into your server's `types.xml` and `events.xml` files. Do not replace your existing files — merge only the new entries.
Helicopter vehicles are set to `nominal=0` and `min=0` by default. This prevents the central economy from automatically spawning or managing helicopter counts. Use the `events.xml` entries (or your own admin spawning tools) to place helicopters at fixed locations instead.

## Download ready-to-go files
Don't want to copy-paste? Grab a complete, ready-to-merge bundle. It contains `types.xml` (every helicopter **and** all door / wheel / item entries), `events.xml` (fixed-spawn events, off by default), `cfgeventspawns.xml` (map position template), **ready-made trader files for TraderPlus, Trader by Dr Jones and DayZ Expansion Market** (pre-priced), and a setup `README`. **The same files also ship inside the mod's `Info` folder**, so everyone who owns the mod already has them.
**Merge, don't replace.** Almost every file in this bundle is **merged into a file you already have** on your server — open your existing `types.xml`, `events.xml`, `cfgeventspawns.xml` and trader config and **paste the new entries in**. Don't drop these in to overwrite your server's files, or you'll wipe your own setup. The one exception is the **Expansion Market** `.json`, which is a new category file you add to your `Market` folder. The included `README` spells this out file-by-file.
types · events · cfgeventspawns · 3 trader files · README — all six helicopters
**How parts spawn:** helicopter doors and wheels are livery-specific and set to `nominal=0` (tracked for cleanup only — no loot spam). The **Battery, Repair Kit and Fuel Drum** spawn in loot so players can fit, repair and refuel. Helicopters themselves never auto-spawn — sell them at a trader or enable an event.
## Do you even need to edit types.xml?
| You want… | What to do |
| ------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------- |
| Helicopters sold by **traders** (TraderPlus, Expansion Market, Dr Jones) | **Nothing here** — just use the classnames in your trader config (ready-made files below). |
| Helicopters placed at **fixed map locations** | Add an `events.xml` entry + a matching `cfgeventspawns.xml` position (both ship in the bundle). |
| Helicopters spawned by the **central economy** | Add the `types.xml` entry and raise its `nominal` / `min`. |
***
## cfgeconomycore.xml — not required
**No `cfgeconomycore.xml` edit is needed.** As of **v0.2.1** the helicopters are built on DayZ's native **`CarScript`** base class, which the Central Economy already treats as a vehicle root. Helicopters persist across server restarts automatically — there is **nothing to register**.
**Upgrading from v0.2?** v0.2 was built on the `Transport` class and required a manual `` entry inside the `` block of your `cfgeconomycore.xml`. As of v0.2.1 that entry is **no longer used** — safely **remove it**. You should also **wipe existing helicopter persistence once** when updating, as the save format changed with the base-class migration.
***
## types.xml
### Helicopters
All helicopter variants. Economy-managed spawn is disabled by default (`nominal=0`, `min=0`). Adjust `lifetime` to control how long an abandoned helicopter persists before the server removes it.

### Doors
Doors that have been removed from a helicopter become physical items in the world. Add these entries so they persist correctly and don't vanish on server restart.

### Required Items
The **Helicopter Battery** is required to start a helicopter; the **Repair Kit** and **Fuel Drum** are optional repair/refuel tools. Add them to your types.xml so the central economy can manage them correctly.
```xml theme={null}

14400

100
```
Adjust the `nominal`, `min`, and `restock` values for `CZ_HelicopterBattery`, `CZ_HelicopterRepairKit`, and `CZAutoz_HeliDrum` to match how commonly you want them available on your server. The values above are a reasonable starting point for a mid-rarity loot economy. For `CZAutoz_HeliDrum`, `quantmin`/`quantmax` set how full each drum spawns (20–70%).
***
## events.xml
Each event entry below places one helicopter variant at a fixed position on the map. Set `active=1` to enable a spawn and configure the `pos` tag with your chosen coordinates. All events default to `active=0` so nothing spawns until you explicitly enable it.
These events use `position=fixed`. You must add a matching `` position entry in your `cfgEventSpawns.xml` (or equivalent) with the world coordinates where you want each helicopter to appear.

## Using helicopters with traders
Every classname works directly in trader mods — and you don't have to build the configs yourself. The mod ships **ready-made, pre-priced trader files for all three popular systems**, inside its `Info` folder and in the [download bundle above](#download-ready-to-go-files). The helicopters, every livery variant **and** the doors, wheels and equipment items are already listed, with matching prices across all three.
| Trader mod | File to use | How to install |
| ------------------------- | ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Trader by Dr Jones** | `Trader_DrJones.txt` | Open your existing `TraderConfig.txt` and **merge in** the `` blocks. |
| **TraderPlus** | `Trader_TraderPlus.json` | **Merge** the categories into the `TraderCategories` array of your existing `TraderPlusPriceConfig.json`. |
| **DayZ Expansion Market** | `Trader_ExpansionMarket.json` | **Add** it to your profile's `ExpansionMod\Market\` folder as a new category file — it sits alongside your existing market files and **replaces nothing** (or merge its `Items` into one of your existing categories). |
**These are merge-in snippets, not replacements.** For Dr Jones and TraderPlus you **open your existing config and paste the new entries in** — don't overwrite your file, or you'll wipe your current trader setup. Only the **Expansion Market** file is a standalone new category file you drop into your `Market` folder.
In the **Expansion Market** file, helicopters include `SpawnAttachments` (Expansion car key, helicopter battery, headlight, and that livery's doors and wheels) so they're delivered **fully built**. Prices are a sensible starting point — edit them to suit your economy. `types.xml` is **not** required for trader-only spawning.
**Pre-set prices** (identical across all three systems, fully adjustable): helicopters range from 1,000,000 (MH-6 / MD500) to 3,000,000 (AW101 Merlin); doors and wheels 5,000; Battery / Repair Kit / Fuel Drum 25,000 / 18,000 / 12,000. Sell-back is \~27% on vehicles, 40% on parts and items.
**Whitelisting still applies, however you spawn them.** A CZ Autoz helicopter will spawn and persist on a non-whitelisted server — but the **engine won't start** until your server IP is whitelisted. See [Required Items & Dependencies](/server-config/required-items).
