Remote sites
Supplying villages, weather stations and work camps in mountains, taiga and on islands where roads are missing or seasonal.
Cargo unmanned systems
Heavy cargo, where roads don’t reach
SkyArtDynamics designs cargo multicopters for civilian work: supplying remote sites, construction, energy and emergency relief. Our first major development is the S400, with a 400 kg take-off weight.

Company
Engineering for a sky that works
SkyArtDynamics Inc. is an engineering company developing heavy unmanned platforms for civilian logistics and industry. We build machines that can be serviced in the field, with no special tools and no queue at a service centre.
Our approach is simple: every system is calculated first, proven on the test bench next, and only then flown. The S400 is the company’s first major project and the base for the next family of aircraft.
SafetyThrust and power redundancy are part of the layout from the first sketch.
ServiceabilityModules are swapped by hand on site, not in a workshop.

Development
S400: one platform, several configurations
Six battery modules in a row along the body and a removable hybrid module on top. Pick the configuration for the job: more payload or more time in the air.

- arms fold along the body: ≈1.92 × 1.08 m
Values are estimates and will be refined after prototype testing.
Applications
Where a cargo copter is needed
The S400 fills the gap between light delivery drones and helicopters: it lifts hundreds of kilograms, takes off from a small pad and needs no airfield.
Energy and telecom
Delivering equipment and materials to power-line pylons and telecom towers with no access roads or heavy machinery.
Construction
Lifting materials onto roofs and into tight urban sites where a crane won’t fit.
Emergency relief
Delivering water, medicine and gear to flood, fire and rubble zones when the ground route is cut off.
Maritime logistics
Moving spare parts and cargo between shore, ships and offshore platforms.
Forestry and farming
Work over large areas: deliveries to forest plots, fertiliser application, heavy-sensor monitoring.
Engineering
What’s built into the design
Coaxial rotor pairs
Eight motors on four arms. The layout is designed to stay controllable if one motor fails.
One-person battery swap
Modules up to 20 kg slide in from the side at waist height. The aircraft is ready for the next sortie in minutes.
Hybrid module
A removable generator module on top extends flight time to about an hour. Without it the aircraft stays fully electric.
Folding arms
The arms fold along the body so the copter fits in a trailer or a van.
Roadmap
