# Introduction
> Premium DayZ mods by Callatic — a fully-simulated helicopter flight system and a 43-strong range of drivable cars, trucks and military vehicles in 232 colour and livery variants, each mod unlocked by its own server-IP whitelist.
**CZ Autoz** (by Callatic) builds two premium mod lines for DayZ. They share the same server-IP whitelisting system and this documentation site — pick the one you're setting up:
Six fully-simulated aircraft — physics-based flight, Autohover, cabin walk, six damage zones, autorotation and an in-game fleet admin panel.
43 drivable cars, trucks and military vehicles — supercars, JDM, off-road, armoured and everyday — in 232 colour & livery variants across nine packs/tiers plus standalone single-vehicle mods.
**Each mod is whitelisted on its own.** Every CZ Autoz mod has its own server-IP whitelist — managed through the same #ip-whitelisting bot. Whitelist each mod you run, or use submit-all to do everything you own at once. See [Whitelisting](/vehicles/whitelisting).

## The Helicopter Fleet
Six aircraft — from the nimble open-air **MD500** to the 18-seat **AW101 Merlin** — each with its own mass, drag and handling feel, and 19 colour/livery variants in total. Built on DayZ's native `CarScript` base for native persistence and broad mod compatibility.

## The Vehicle Range
43 vehicles — **232** spawnable colour and livery variants — spanning everyday cars, supercars, JDM tuners, off-road rigs, vans and military hardware, sold as **packs & tiers** (curated multi-vehicle bundles) or as **standalone single-vehicle mods**. The whole range is **all-wheel drive with fully resimulated handling** — grip, power and top speed tuned to each car's real-life character. Every vehicle ships with ready-made `types.xml`, colour variants, and the same per-mod server-IP whitelisting.
Curated mixed-class car tiers
Bugatti Chiron · Rayfield Caliburn · McLaren 600LT
Supra · Skyline GTR R34 · RX7 · 300ZX
Raptor · Gladiator · Unimog · BTR-4E
Humvee · MRAP · HEMTT · Zetros
Chevrolet G20 · Mercedes Sprinter
Every pack and tier, colour variants, classnames, whitelisting and ready-made `types.xml`.

## What both lines share
Each CZ Autoz mod has its own whitelist — whitelist every pack, tier, vehicle and the helicopter you run (or use submit-all). Not whitelisted = vehicles spawn but won't start; helicopters disable flight.
Both lines run on DayZ's native `CarScript` vehicle base — native Central Economy persistence, no custom root-class registration needed.
Live JSON configs (helicopters), ready-made `types.xml`/`events.xml` (vehicles), and step-by-step install guides for both.
