Mod Compatibility

Under the bonnet the helicopters are built the same way DayZ builds a car, so most vehicle mods treat them like any other vehicle. Where a mod expects something a car does but a helicopter does not — an engine that starts differently, a door that is not a car door — we add that behaviour on our side. Every one of these fixes is optional in the truest sense: you do not have to install anything, and if you do not run a given mod, your server behaves exactly as it always did.

Everything in the table was checked by reading the other mod’s own code, not by guessing from how it behaved in game. Most rows need nothing at all from you. The two that do need something are marked in the last column.

Verified mods

Mod	What works	You need to
MuchCarKey	A locked helicopter cannot be boarded, its outside doors and ramp will not open, and it cannot be picked up on another helicopter’s sling. This works whatever order the mods load in. If you have turned off `CanStartWithoutKey`, starting a keyed helicopter needs its key exactly as it would on a car — in hand or in the player’s inventory, master keys included — and that applies to the autopilot starting the engine too. Its clean-up of unused vehicles now counts flying as using the aircraft, so a helicopter that is flown every day but never re-locked is no longer deleted.	Nothing
DayZ Expansion (Vehicles / Market)	A locked helicopter cannot be boarded, opened or slung. Selling back through the Market was never affected.	Nothing
Dr Jones Trader	Selling a helicopter back works. The pilot is recorded as the owner the moment the engine starts, which is the same point a car records it — without that, the trader used to refuse the sale. Its vehicle lock is respected whatever order the mods load in, and a locked helicopter cannot be slung.	Nothing
TraderPlus	Parking in the TraderPlus Garage works, because ownership is recorded when the engine starts. Selling through the receipt system was never affected. Its vehicle lock is respected whatever order the mods load in, and a locked helicopter cannot be slung.	Nothing
TraderX	Selling a helicopter back works, because ownership is recorded when the engine starts.	Nothing
AutolockVehicles	Starting the engine cancels its auto-lock countdown, exactly as starting a car does, so it can no longer lock a helicopter with the pilot still sat in it.	Nothing
VirtualGarageFull, MuchCarPark	We read through each of these and found nothing that needed fixing on our side.	Nothing
CarCover	Covering and uncovering a helicopter keeps its fuel level, its extra cargo modules with everything in them, and a Barrel Helicopter’s owner (since v0.4.6). Helicopters covered before v0.4.6 were already missing their modules, and a Barrel Helicopter’s owner, when they were covered. The covers made for the helicopters come in the separate CZ Autoz Heli Covers mod, which only works with CarCover loaded.	Nothing
Vehicle3PP (third-person camera)	It applies its list of allowed vehicles to the helicopters just as it does to cars, so without an entry your pilots are stuck in first person.	Add `CZAutoz_Helicopter_Base` to its list — that single line covers every helicopter and every paint scheme. Details →
COCAs_NoVehicleDamageMOD, NoVehicleDamage (2019)	These work, but only if they load before the helicopters. Loaded after, they take over the vehicle collision handling and never pass it on, which stops the rotors colliding with anything and stops other players seeing the rotors spin or the aircraft tilt.	List them earlier than the helicopters in your `-mod=` line. Details →
CFTools / GameLabs, VPP, COT (admin repair and spawn)	Repairing a helicopter from one of these admin tools no longer bolts on cargo modules you never asked for. Spawning works too. If a client crashes when one is spawned, that client is on a different version of the mod from the server.	Keep every client and the server on the same version
Vehicle recovery and teleport mods	A parked helicopter moved by an outside tool now appears in its new place correctly for every player.	Nothing
Chat mods	While a player is typing, every helicopter key stops responding — the Pilot Panel, the admin panel and the flight controls. This covers the standard DayZ chat box and any chat mod that uses a normal text box.	Nothing
FoXy No Fly Zone	The helicopters are registered with it automatically, so its no-fly areas work on them: it can tell whether a helicopter’s engine is running, shut that engine down, and identify the pilot.	Nothing
Survivor Animations	The helicopters use its helicopter sitting pose, so crew sit correctly instead of dropping into a car pose.	Nothing

Two different lock behaviours. Refusing to let anyone board a locked helicopter, or open its outside doors or ramp, always happens and cannot be switched off. Refusing to sling a locked vehicle is separate and follows the sling.respectLocks setting in Global Settings, which is on by default.

Not listed?

A mod that is not in the table simply has not been checked yet. It does not mean it clashes. Because the helicopters are built the way DayZ builds a car, most vehicle mods just work. If something does misbehave with a mod you run, tell us in Discord with the mod’s name and what you saw, and we will read through its code the same way.

The lock and trader work went in across v0.4.0 to v0.4.3. If a row above does not match what you are seeing, check that your server and every player are on the current version first — see the changelog.
