Positioning

H-100 is a large coaxial eight-rotor multirotor built for heavy payload operations where carrying capacity, endurance under load, and structural redundancy matter more than compactness. The airframe accepts a seated occupant or mission equipment in the central cabin, and it supports both onboard piloted control and ground remote control.

The eight-motor coaxial arrangement means a single- or dual-motor failure does not immediately remove lift. Power is distributed through a high-current bus with pre-charge and emergency stop, and battery packs are removable for turnaround between missions.

Certification and compliance

H-100 is a manned-capable multirotor intended for approved operations. Aircraft certification, airworthiness approval, and operational authorisation are the operator's responsibility and depend on the jurisdiction of operation. Montline does not provide airworthiness certification, and the figures on this page are not a substitute for an approved flight manual or operating permit.

Manned flight requires regulatory approval in every jurisdiction where it is flown, and those approvals are granted to the operator, not supplied with the aircraft. We provide the technical documentation your application needs. Operating limits, emergency procedures and crew requirements come from the approved documentation for your operation.

Payload integration

Payload integration starts with three checks: weight and balance must sit within the deck load limit and stay inside the balance envelope; payload draw must fit the remaining bus capacity including peak current; and signal type, bandwidth and timing must match the avionics interfaces.

Frequently asked questions

Can the H-100 be configured for a specific mission?

Yes. The H-100 is configured to the mission rather than sold as a fixed package: payload combination, data link, power and mechanical interfaces are settled before the order, and acceptance criteria are agreed before work starts.

Under what conditions were the specifications measured?

The table gives typical-condition values. Actual figures depend on payload, wind and dispatch pattern; per-item conditions are confirmed with the project.

How are price and lead time given?

There is no published price list. Pricing follows configuration and quantity; production is scheduled against orders, and lead time is confirmed with the order.

Does Montline provide type certification?

No. Airworthiness certification and operational approval are the operator's responsibility; Montline does not provide type certification.
