A little bit of lore, which is impossible to keep silent about:
The Heavystar brand was created as an homage to the real vehicle prototypes that served as the basis for this kit. The name reflects the essence: "heavy" indicates the ability of equipment to cope with serious work tasks, and "star" indicates that it is a "star" in performing such hard work. In addition, this is a reference to the popular suffix used by real manufacturers to designate platforms of this period.
The Gavril brand was chosen as the "parent company" for Heavystar, taking into account their specialization in medium and heavy—duty vehicles. The Heavystar line includes three universal configurations: PE (passenger engineered buses), LD (light duty trucks) and HD (heavy duty trucks).

THE MAIN FEATURES OF THIS MOD ARE
- A functional system for checking lighting devices
- Simple but working anti-theft alarm system for bus
- Proprietary software code for controlling the engine fan and cooling system
- Special light panels, additional lighting and its operating modes
- Proprietary program code for the oil pressure indicator arrow on the dashboard
- Unique sounds in the cabin and some original engine sounds
- Functional rotating flashing light ("roto-ray" type)

This mod is part of a planned series of three sets; the version presented here belongs to the second generation. The first (Heavystar I) and third (Heavystar III) generations are planned to be released in the future, but the exact timing of their appearance is still unknown. This set opens the series and includes the most in—demand platforms - a kind of "trial balloon" designed to evaluate the possibilities of the mod and the reaction to it from the community.

Interesting fact: in fashion, you can find a lot of funny or informative details, inscriptions and names — a kind of "Easter eggs".
