Where Are the Config Files?

All config files are automatically generated on the first server start at:
$profile: refers to your DayZ server profile directory — the folder that contains your BattlEye, mpmissions, and .RPT log files.

​
File List

Each helicopter variant gets its own JSON config file. With 19 spawnable variants across 6 helicopters, you will see 19 individual config files plus mod_config.json for global settings. MD500 Civilian MH-6 Little Bird SA342M Gazelle UH-1H Iroquois MH-60L Blackhawk AW101 Merlin Global

​
How to Edit

  1. Navigate to $profile:\CZAutoz_Heli\
  2. Open the JSON file for the helicopter you want to adjust in any text editor
  3. Change the values
  4. Restart the server — direct edits to the JSON files are read on startup, so they only take effect on the next start
Prefer not to restart? The in-game Admin Panel edits the same settings and applies them live (since v0.2.3) — every spawned helicopter and connected player updates instantly, no restart or reconnect. Only direct JSON file edits need a restart.
Per-helicopter flight values (flight.liftMultiplier, control.pitchStrength, control.bankStrength, etc.) are pre-tuned by the development team and are not recommended to change. Modifying them can result in helicopters that are difficult or impossible to fly. Adjust at your own risk.
The global settings in mod_config.json (cargo modules, repair, toggles, logging) are completely safe to adjust — they don’t affect flight behaviour.

​
How to Reset to Defaults

Delete the helicopter’s JSON file and restart. It will be regenerated with all default values.

Config Migration on Version Update

Since v0.2.3, a mod update migrates your configs in place — both mod_config.json and all per-helicopter files. New keys are added, removed keys cleaned up, and all your custom values are kept. This keeps your configs in sync with new and changed keys without losing your tuning.
  • Your originals are backed up first to $profile:\CZAutoz_Heli\Backups\v<oldversion>_<date>\ before any migration touches a file
  • Custom values are carried over — only the schema (which keys exist) is updated, not your settings
  • Only when first moving from v0.2.2-or-earlier onto a v0.2.3+ build might a one-time re-apply be needed
The migration is triggered by the version field stored in mod_config.json changing. Do not manually edit it — let the mod set it.

Configuration Reference

The full configuration reference lives on this documentation site — see Global Settings for mod_config.json and Per-Helicopter Settings for the per-variant files.
The old in-game $profile:\CZAutoz_Heli\Guide\ reference folder is no longer generated as of v0.2 — all configuration documentation now lives here on the docs site.
