v0.4.8 needs DayZ 1.30. It will not run on DayZ 1.29, so update your server and make sure your players are on 1.30 too. Going back to v0.4.7 afterwards is not supported: helicopters saved by v0.4.8 will not load correctly on older versions.

Purchase CZ Autoz Helicopter Core System

Once you’re in the Discord, head to the purchase channel and follow the bot’s instructions to purchase the CZ Autoz Helicopter Core System.

Whitelist Your Server IP

After purchasing, navigate to the IP whitelisting channel and use the CZ Autoz Bot to register your server’s public IP address. The mod will not function on non-whitelisted servers.

IP Whitelisting Channel

Open the IP whitelisting channel in Discord

Or whitelist on the website

Set your keyword, add server IPs, declare your free test server and buy extra slots at czautoz.co.uk/whitelist — kept perfectly in sync with the Discord bot.
Make sure you submit your server’s public IP address, not your home/local IP. If your server IP ever changes (e.g. you switch hosts), return here and re-whitelist the new IP.

Download the PBOs

Navigate to the mod download channel in the CZ Autoz Discord and download the two PBO files.

Mod Download Channel

Open the mod download channel in Discord
You will receive 2 PBO files:
  • CZAutozHelicopter_Scripts.pbo — client and server scripts
  • CZAutozHelicopters.pbo — helicopter assets (models, configs, textures)
5

Add the PBOs to Your Server Mod Pack

Copy both PBO files into your server’s mod pack. A server mod pack is a folder containing a collection of PBO files that gets loaded by your server — it typically already exists if you run other mods.Place the PBOs inside the Addons\ folder of your mod pack:
6

Sign the PBOs with DS Utils

DayZ servers require all PBOs to be signed with a private key before they are accepted. Use DS Utils to sign both PBO files with your server’s private key.
  1. Open DS Utils
  2. Load your .biprivatekey file
  3. Sign both PBO files — this generates a .bisign signature file alongside each PBO
Your .biprivatekey must never be shared with anyone. It is your private signing key — anyone who has it can sign PBOs as if they were you. Keep it private and back it up securely.Your .bikey (public key) is safe to share and distribute — it is what players and servers use to verify signatures.
Copy your .bikey (public key) into the Keys\ folder in the root of your server:
Without the .bikey in the Keys\ folder the server will reject the PBOs and the mod will not load.
7

Publish Your Mod Pack to Steam Workshop

Update or publish your mod pack to the Steam Workshop using the Publisher tool inside DayZ Tools:
  1. Open DayZ Tools → Publisher
  2. Select your mod pack folder (@YourModPack)
  3. Upload or update the Workshop item
If this is a brand new Workshop upload: after the initial publish, you must run a second update immediately — select the same @ModFolder again in Publisher and push the update. This second upload generates the Workshop Publisher ID, which is required for the mod to function correctly across clients and servers. Without it, the mod may not be publicly downloadable, may fail to load on clients, or may not be recognised by the server correctly.
Once published and the Publisher ID is confirmed, ensure the mod pack is loaded on both client and server side. How you load it depends on your setup — if you manage your server manually, add it to your -mod= startup parameter; if you use a server management panel (e.g. Nitrado, GTXGaming, PteroPanel, or Architect Manager by CF Tools), it will have its own mod management section where you can enable Workshop mods directly.
No Community Framework (CF) needed. The helicopter mod is fully standalone — it does not require @CF or any other framework dependency.Purpose-built integrations — Survivor Animations (proper pilot pose), VPP Admin Tools, Community Online Tools, Push-a-Car and FoXy’s No Fly Zone — are optional and auto-detected: load them and they just work, with nothing to configure.Other vehicle mods such as DayZ Expansion, MuchCarKey, TraderPlus CarLock and RaG work simply because the helicopters are ordinary DayZ vehicles as far as the game is concerned — those mods treat a helicopter exactly as they treat any car.
If you are updating an existing Workshop mod pack, players will automatically receive the updated PBOs the next time they launch the game with your server selected.

Start the Server

Start your server. On the first boot the mod automatically generates its whole configuration tree under $profile:\CZAutoz_Heli\:
The per-helicopter files sit inside HeliConfigs\, not in the top folder, and each is named after its classname — <Classname>_Config.json. There are 48 of them, one for every spawnable colour variant.
Full configuration documentation lives on this docs site — see Quick Start and the per-helicopter settings pages for every option.

Make Yourself an Admin

Admins and roles live in their own file — $profile:\CZAutoz_Heli\permissions_admins_config.json — generated alongside mod_config.json on that first boot. Add your Steam64 ID there with the owner role for full access, then restart the server and press F10 in game to open the Admin Panel.

Add Items to Your Loot Economy

Add the two required item classnames to your server’s types.xml so they can spawn in the world.See Required Items for ready-to-use types.xml entries.

Persistence — No Setup Required

Since v0.2.1 the helicopters are built on DayZ’s own vehicle base, so the game saves them the same way it saves cars. There is nothing to set up. Helicopters stay where you left them across server restarts.
Coming from v0.2? The old v0.2 build needed a manual <rootclass name="CZAutoz_Helicopter_Script" act="car" reportMemoryLOD="no" /> line inside the <classes> block of your mission’s cfgeconomycore.xml. From v0.2.1 that line is no longer needed and you can delete it. You should also wipe your saved helicopters once when you update, because the way they are saved changed.
12

Add Helicopters to Your Server

Add helicopter classnames to your server’s events, trader, or loot config. Every spawnable classname — all twelve airframes and each of their variants — is listed on the Helicopter Overview page.For ready-to-use types.xml and events.xml entries covering every variant, door item, and wheel, see types.xml & events.xml.Example classnames:
13

Configure & Tune (Optional)

Edit the JSON files in $profile:\CZAutoz_Heli\ to tune flight physics, damage zones, fuel, and more to suit your server. The keys are grouped into nested sections:
  • mod_config.json — logging, flight, simple, advanced, crew, rotor, autoPilot, sling, barrelHeli, repair, refuel, cargoModules and keybinds. simple and advanced hold the settings for the Simple and Advanced flight modes separately; everything else applies whatever flight mode you run. Admins and roles are not in this file — they are in permissions_admins_config.json, and any old admin block still in mod_config.json is moved there and removed on the next start
  • HeliConfigs\<Classname>_Config.json — flight, altitude, aerodynamics, control (with a nested response block), autorotation, tailRotorFailure, damage (with nested zones and burn blocks), fuel, battery, audio, camera and sling. The two Ospreys’ files also have a tiltRotor section, and the Chinooks’ and Ospreys’ files have no tailRotorFailure section
See Quick Start for a full walkthrough of the configuration system.

After Installation

  • Since v0.2.3, a mod update migrates your configs in place — new keys are added, removed keys cleaned up, and all your custom values are kept (originals are still backed up first to $profile:\CZAutoz_Heli\Backups\v<oldversion>_<date>\). Only when first moving from v0.2.2-or-earlier onto a v0.2.3+ build might a one-time re-apply be needed
  • Changes made in the in-game Admin Panel apply live — they update every spawned helicopter and connected player instantly, no restart or reconnect (since v0.2.3). Only direct edits to the JSON config files need a server restart, since those are read on startup
  • If anything isn’t working, see the Common Issues page
If helicopters appear in-game but controls are unresponsive or the mod behaves incorrectly, your server IP is most likely not whitelisted or the whitelisted IP doesn’t match your current server IP.
