CZ Autoz Helicopter brings six fully-simulated aircraft to DayZ, each with its own weight, drag, and handling feel. Every aspect of the flight model, damage system, and gameplay behaviour can be tuned by server owners through simple JSON config files — no modding knowledge required.

Six aircraft from the nimble MD500 to the 18-seat AW101 Merlin

Features

Physics flight model, Autohover, cabin mode, damage zones, and more

Controls

Full key reference for flight, engine, lights, repair, and crew actions

Quick Start

Purchase, whitelist, install, and get flying in minutes

Server Config

40+ tunable parameters per helicopter via JSON config files

Roadmap

Core Features at a Glance

  • CarScript-based flight model — built on DayZ’s native CarScript base class (for native mod compatibility and native persistence), with force/kinematic physics and restored smooth 1.28-style handling so the helicopter moves, banks, and turns smoothly through the world; every nearby player sees and hears it whether or not a pilot is seated (on-screen visual body-frame smoothing on the 1.29 engine is still being refined)
  • Physics-based flight — each helicopter has unique mass, drag, and control feel
  • Autohover — press X to lock into a stable hover; holds altitude, heading, and position
  • Co-pilot control priority — only one cockpit seat holds flight control at a time; press T to hand control to the other seat, and it passes automatically if the holder leaves or dies
  • Full controller support — fly entirely on a gamepad (cyclic on the left stick, collective on the triggers, yaw on the shoulder buttons); every binding is rebindable
  • In-game admin panel — open with F10 to manage the whole fleet: teleport, repair, refuel, reset, delete, repair all, delete empty, reload configs live, plus a map view and role-based permissions
  • 6 independent damage zones — Body, Engine, Chassis, Fuel, Main Rotor, Tail Rotor; each toggleable per server
  • Wreck fire — destroyed helicopters catch fire and burn for a configurable time, with a fire-damage area that hurts players standing too close (suppressed underwater)
  • Autorotation — engine-off rotor inertia glide allows a controlled emergency landing; tilt the cyclic to glide and steer the descent
  • Cabin Mode — pilot or co-pilot can leave their cockpit seat via Move to Cabin and walk freely inside the cabin (UH-1H, Blackhawk). The AW101 Merlin uses Seat Exit Free Walk — all seats exit into the enclosed fuselage natively. Walk-on linking also available on UH-1H, Blackhawk, and MH-6
  • Battery system — HelicopterBattery required before engine start; charges while running, drains on lights
  • Repair system — HelicopterRepairKit repairs all damage zones (engine off, grounded)
  • Fuel & refuelling — refuel from a jerry can, or pump-refuel directly at a working map fuel station (vanilla, Enoch, or Simple Gas Pump) with no jerry can needed
  • Cargo — base storage built in, plus up to 10 extra 1,000-slot modules per helicopter
  • HUD — airspeed (knots), altitude AGL, health bar, Autohover status, and a control indicator (green when you hold flight control, red when you do not)
  • Fuel warning — audio beeps at configurable threshold, increasing frequency as fuel drops
  • Activity logging — player events logged with display name and Steam GUID
  • Config backup on update — a mod version update regenerates all configs from defaults and automatically backs up your previous configs first (to $profile:\CZAutoz_Heli\Backups\), so you can re-apply your settings

Mod Compatibility

Community Framework (CF) is a required dependency — it must be loaded before this mod in your server’s load order. Each integration below is optional and auto-detected, only activating when that mod is also loaded:
  • DayZ Expansion — registered as Expansion vehicles; respected by safe zones, routed through Expansion damage/explosion, and persisted via ModStorage
  • MuchCarKey — lock/unlock, assign keys, show owner name, and optionally require the key to start the engine
  • TraderPlus CarLock — password lock/unlock with an on-screen menu, attach/detach, lockpicking, and lock sounds
  • VPP Admin Tools — the /refuel chat command fully repairs, refuels, and maxes every damage zone
  • RaG Core — enter/exit, door, deletion, and weapon-hit events written to RaG’s vehicle activity log
  • Community Online Tools (COT) — appear in the vehicle manager, spawn with the correct doors, and included in bulk delete
  • Push — the vanilla push action works on a grounded helicopter, scaled per variant

Config Files

All configuration files are generated automatically on first server start at:
$profile:\CZAutoz_Heli\
Each helicopter variant gets its own JSON config file — 19 files in total across 6 helicopters, plus mod_config.json for global settings.

mod_config.jsonGlobal settings for all helicopters
As of v0.2 the config keys are grouped into nested CZAutoz_ sections — mod_config.json is split into logging, features, gameplay, repair, refuel, extraModules and admin, and each per-helicopter file into flight, altitude, aerodynamics, control, autorotation, tailRotorFailure, damage, fuel, battery, audio and camera. See Quick Start for full editing instructions and how to reset to defaults.
Every configuration option is fully documented on this site at docs.czautoz.co.uk — see the Server Config section. We recommend using this site as your primary reference.
