Edit $profile:\CZAutoz_Heli\mod_config.json to change settings that apply to all helicopters on your server. As of v0.2 the file is organised into clear sectionslogging, features, gameplay, repair, refuel, extraModules and admin. Each setting below is shown by its full path (for example features.autoHoverEnabled). Delete this file and restart to regenerate it with all default values.
These settings are safe to adjust freely — they control gameplay features like cargo, repair, fuel warnings, logging, and server-wide toggles. Unlike the per-helicopter flight physics values, there is no risk of breaking flight behaviour by changing these.
When the mod updates to a new version, mod_config.json is regenerated from defaults along with every other config — new keys appear, but your custom values revert to defaults at the same time. Your previous configs are backed up automatically first to $profile:\CZAutoz_Heli\Backups\v<oldversion>_<date>\, so re-apply your settings after updating by copying them back from the backup folder.

Extra Cargo Modules

Each extra module adds 1,000 inventory slots. Maximum 10 modules per helicopter.
SettingHelicopterMax total slots
extraModules.md500MD500 Civilian10,250
extraModules.mh6MH-6 Little Bird10,250
extraModules.sa342mSA342M Gazelle10,250
extraModules.uh1hUH-1H Iroquois10,500
extraModules.blackhawkMH-60L Blackhawk10,500
extraModules.merlinAW101 Merlin11,000
SettingWhat it doesDefault
features.seatedCargoAccess1 = crew can open extra cargo while seated. 0 = locked while seated.1

Repair

All repairs require HelicopterRepairKit in hands, engine off, helicopter grounded.
SettingWhat it doesDefault
repair.kitUsesNumber of repairs a kit can perform before going ruined.5
repair.rotorRepairTimeHold time in seconds to repair a rotor.45
repair.zoneRepairTimeHold time in seconds to repair a body/engine/chassis/fuel zone.30
repair.globalHpPctGlobal HP fraction added per repair (0.10 = +10% global HP per action).0.10
Zone repair is progressive — one hold repairs one damage level. Full repair of a heavily damaged zone may require multiple holds.

Refuelling

Controls how much fuel each container type adds and how quickly it drains during the refuel action.

Refuel Amounts

The amount of fuel added is expressed as a fraction of the helicopter’s total tank capacity — so the same setting applies consistently regardless of which helicopter is being refuelled.
SettingWhat it doesDefault
refuel.canisterPctFraction of tank added per full CanisterGasoline (jerry can). 0.10 = 10% per can, 10 cans to fill any helicopter.0.10
refuel.drumPctFraction of tank added per full CZAutoz_HeliDrum. 0.50 = 50% per drum, 2 drums to fill any helicopter from empty.0.50
refuel.bottlePctFraction of tank added per full Bottle_Base item (water bottles, glass bottles, etc.).0.005
refuel.defaultPctFraction of tank added per full unrecognised container (catch-all for modded fuel items).0.005

Refuel Drain Speed

Controls how fast the container empties during the refuel action. Higher values drain the container faster, reducing the wall-clock time to complete a fill.
SettingWhat it doesDefault
refuel.canisterRateDrain speed multiplier for CanisterGasoline. 1.0 = ~40 s for a full can. 2.0 = ~20 s.1.0
refuel.drumRateDrain speed multiplier for CZAutoz_HeliDrum. Default 5.0 makes a full drum take the same wall-clock time as a full canister despite holding 5× the fuel.5.0
refuel.bottleRateDrain speed multiplier for Bottle_Base items.1.0
refuel.defaultRateDrain speed multiplier for unrecognised containers (catch-all).1.0

Thresholds & Toggles

SettingWhat it doesDefault
gameplay.fuelWarnThresholdFuel fraction at which warning beeps begin. 0.20 = starts at 20% remaining.0.20
gameplay.playerCrashDamageMaxMax HP damage to crew per hard impact (requires damage.playerCrashDamageEnabled = 1 in the helicopter’s config).75
gameplay.engineHoldTimeHold duration in seconds for the Start Engine and Stop Engine action circles.1.0
features.rotorBladeShear1 = rotor blades shear off on geometry contact (trees, buildings, terrain). 0 = no shear.1
features.rotorDiscCollision1 = spinning rotor disc has physical collision. 0 = no disc collision.1
features.rotorPlayerKillEnabled1 = players entering a spinning rotor disc are instantly killed. 0 = disabled.1
features.groundFlipRecovery1 = pressing X while grounded and inverted flips the helicopter upright. 0 = disabled.0
features.autoHoverEnabled1 = Autohover works normally. 0 = disabled server-wide (X key does nothing).1
features.cabinModeEnabled1 = Cabin Mode enabled. 0 = disabled server-wide for all helicopters.1
features.freeLookAlwaysOn1 = free look is always active for the pilot (no need to hold the key). 0 = default DayZ hold-to-free-look behaviour.0
features.autoShutdownOnExit1 = engine shuts off automatically when the pilot exits their seat while the helicopter is grounded and the engine is running. 0 = disabled.0
features.autoHoverOnExit1 = Autohover automatically engages when the pilot exits their seat while the helicopter is airborne — helicopter holds position until a new pilot boards. 0 = no autohover on exit (helicopter continues on its current trajectory).1
features.doorAction3rdPerson1 = the seated door open/close action also appears in 3rd-person view. 0 = 1st-person only.0

Admin Access — Roles & Permissions

The admin section controls who can use the in-game Admin Panel (default key F10) and what each role may do. This is easiest to manage from the Admin Panel’s Roles page in-game — the JSON below is simply what that produces.
SettingWhat it doesDefault
admin.whitelistRetryMinutesHow often (in minutes) the server re-checks the whitelist if the first check fails.15
admin.entriesArray of admins. Each entry has a steamID64, a role, and an optional list of extra permissions.[]
admin.rolesArray of custom roles. Each has a name and a list of permissions.[]
"admin": {
  "whitelistRetryMinutes": 15,
  "entries": [
    { "steamID64": "76561198000000000", "role": "owner", "permissions": [] }
  ],
  "roles": [
    { "name": "admin", "permissions": ["heli.list.refuel", "heli.list.delete", "tools.spawn"] }
  ]
}
The built-in owner role always has every permission and can never be locked out. Other roles only get the permissions you grant them — actions a role lacks are still visible in the panel but show “Access denied” when clicked. The mod-config and per-helicopter pages are never editable by non-owner roles. Manage all of this from the Admin Panel → Roles page.

Logging

SettingWhat it doesDefault
logging.CZAutoz_logDebug1 = verbose debug output written to CZAutoz_Heli_debug.log. Only enable when troubleshooting — do not leave on in production.0
logging.CZAutoz_logActivity1 = all player helicopter events logged to a daily file at $profile:\CZAutoz_Heli_Activity_YYYY-MM-DD.log. Each entry includes the player’s display name and Steam GUID. Recommended to enable on all servers.0
logging.CZAutoz_logPhysics1 = physics/flight diagnostics written to the debug log, for tuning and flight-issue investigation. Leave off in production.0

Activity Log Events

The activity log is designed as an admin tool for investigations, compensation, and dispute resolution. Every significant player interaction with a helicopter is recorded with a precise timestamp, player display name, and Steam GUID — giving you a complete, chronological picture of exactly what happened, who was involved, and when. Common admin use cases:
  • Combat logging — confirm whether a player left a helicopter mid-fight or mid-pursuit
  • Theft and griefing — identify who took a helicopter, who was flying it, and what was removed from cargo
  • Compensation requests — verify whether a crash was caused by server-side damage, a rotor shear, or pilot error before compensating
  • Dispute resolution — cross-reference a player’s account of events against the timestamped log
  • Rotor kills — confirm who was piloting when a player was killed by a rotor disc, including both victim and pilot GUIDs
When logging.CZAutoz_logActivity = 1, every event is recorded with a timestamp, the helicopter classname, and the player’s display name and Steam GUID where applicable. All seat, engine, and physics events also include the helicopter’s world position (X/Z coordinates) at the time of the event.

We strongly recommend enabling activity logging on all servers. It has no meaningful performance impact and gives you the full picture you need to handle compensation requests, combat log reports, theft disputes, and any helicopter-related staff situation confidently and fairly. Without it, you are relying entirely on player accounts of what happened.This mod logs all helicopter-specific interactions, but it does not cover general server-wide PvP kills. For complete kill accountability — including who shot who, with what weapon, and when — we recommend also running a dedicated PvP logging mod alongside this one. The two logs complement each other: helicopter activity records the context, a PvP logger records the kill chain.

Whitelist Logs

The mod also generates two dedicated whitelist log files on every server start, regardless of logging.CZAutoz_logActivity:
FileContents
$profile:\CZAutoz_Heli_whitelist_status.logHuman-readable whitelist check result — overwritten on each start
$profile:\CZAutoz_Heli_whitelist_debug.logDetailed whitelist API diagnostics — appended on each check
See Common Issues for how to use these when troubleshooting.
