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
| File | Controls |
|---|
MD500_Civilian_config.json | MD500 Civilian — all variants |
MH6_config.json | MH-6 Little Bird |
SA342M_config.json | SA342M Gazelle |
UH1H_config.json | UH-1H Iroquois — all variants |
MH60LBlackhawk_config.json | MH-60L Blackhawk — all variants |
AW101Merlin_config.json | AW101 Merlin — all variants |
mod_config.json | Global settings for all helicopters |
Sub-variants (e.g. UH1H_Nasa, MH60LBlackhawk_Desert) each get their own JSON file with the same configurable fields as the base type.
How to Edit
- Navigate to
$profile:\CZAutoz_Heli\
- Open the JSON file for the helicopter you want to adjust in any text editor
- Change the values
- Restart the server — changes only take effect on next start
Per-helicopter flight physics values (CZH_liftMultiplier, CZH_pitchStrength, CZH_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.
Auto-Updating Config
When the mod updates and introduces new config keys:
- New keys are automatically added to your existing files
- Your custom values are preserved — nothing is overwritten
- Old configs are backed up to
$profile:\CZAutoz_Heli\backup\ before any changes are made
Do not manually change the CZH_version field in any JSON file. Doing so triggers an automatic config reset for that helicopter, discarding your custom values.
Generated Reference Guide
On every server start, a full configuration reference is written to:
$profile:\CZAutoz_Heli\Guide\description_config_EN.md
Guide\ folder. Open any file in a Markdown viewer (VS Code, Obsidian, GitHub) for a formatted reference.
