Heavy-Lift
eVTOL. Zero
Transloading.
We're engineering the Rello KS450 — a heavy-lift hybrid eVTOL with a modular pod system that eliminates cargo transloading entirely, vertical takeoff and landing from warehouse parking lots, and under 5 minutes on the ground between flights — with a quiet cruise profile for urban and residential flight paths.
Engineering
the end of
transloading
Global logistics operates on a fundamental inefficiency: cargo must be transferred between modes — truck to aircraft to truck — at every node. Each transfer costs time, money, and reliability. Rello Aerotech was founded on a simple premise: the aircraft should be the infrastructure.
The KS450 is engineered so cargo stays sealed in a single module from origin to destination — no transload at any handoff. The specifics of how that handoff works are proprietary; the outcome is not: the transload bottleneck, the defining inefficiency of global logistics, is engineered out entirely. This is not an incremental improvement. It is a structural reimagining of how cargo moves between ground and sky.
Rello KS450
Heavy-Lift Hybrid eVTOL
The KS450 is engineered around a proprietary modular architecture that lets cargo stay sealed in a single module from origin to destination — eliminating the transload entirely.
Key Differentiators
Modular Pod Architecture
A single integrated module carries cargo from origin to destination without a single transload. The architecture that makes this possible is proprietary — the outcome is not.
VTOL at Warehouse Parking Lots
The KS450 takes off and lands vertically with a full payload, operating directly from warehouse parking lots and logistics yards — no runway and no ground infrastructure beyond a flat surface.
Unpaved Runway Capability
Beyond VTOL, the KS450 is runway-capable on unpaved strips, unlocking a vast network of underutilized existing infrastructure for logistics operations.
Quiet Cruise for Urban Flight Paths
A quiet, emissions-aware cruise profile enables operation over urban and residential flight paths — making routine city-to-city cargo flights socially and regulatorily viable.
Performance Specs

Engineered out of the logistics process entirely — cargo never changes hands.
Approximate heavy-lift design target — capacity that rivals ground transport.
The aircraft is back in the air in under five minutes between flights.
Less than 5 minutes on the ground
The KS450 doesn't just eliminate transloading — it eliminates refueling downtime. The ground operation is engineered so that reloading and refueling happen as one, in a single seamless step.
A single, seamless ground step reloads and refuels the aircraft at once. It lands, is turned around, and is back in the air — all in under five minutes, the time a conventional aircraft spends hooking up a fuel truck.
Instant Reload & Refuel
The aircraft is reloaded and refueled in a single seamless step. The specifics of how are proprietary; the outcome is an aircraft back in the air almost instantly.
Sub-Five-Minute Turnaround
The entire ground operation completes in under five minutes, with no manual handling required. The aircraft is airborne again almost instantly.
Parallel Ground Operations
Ground operations run in parallel with flight, not in series — so the next departure is ready the moment the aircraft lands.
Lower Cost Per Flight Hour
High utilization is the single biggest driver of aviation economics. Minimizing ground time maximizes flying hours, driving cost per flight hour to levels previously impossible for heavy-lift air cargo.
Built for time-critical supply chains
The KS450 is purpose-built for sectors where delays are measured in dollars, safety, or human life. Our modular pod architecture serves industries that cannot afford transloading, congestion, or broken cold chains.
Cold-Chain Pharmaceutical Logistics
Temperature-sensitive pharmaceuticals require unbroken cold chains and rapid transit. The KS450 maintains environmental integrity from origin to destination — no transloading, no exposure, no compromise.
AI Data-Center Mechanical Resupply
When a data center goes down, every minute costs millions. The KS450 delivers just-in-time mechanical components — servers, cooling units, power modules — directly to the facility, bypassing ground congestion entirely.
Industrial Mechanical Resupply
Downtime on a production line is measured in lost revenue per hour. The KS450 moves critical industrial spare parts and machinery modules to remote or congested sites on demand, keeping operations continuous.
Medical Supply Logistics
Hospitals and healthcare systems depend on reliable, rapid resupply of medical equipment, pharmaceuticals, and critical care resources. The KS450 delivers cargo sterile, secure, and immediate — no transloading, no delay.
Cold-Chain High-Value Foods & Goods
Premium perishables — fresh seafood, exotic produce, fine wines, and luxury goods — demand unbroken cold chains and speed. The KS450 pod preserves temperature integrity from origin to destination, delivering high-value cargo without compromise.
Built for the architects of global supply chains
Rello Aerotech was founded to solve one of logistics' most persistent structural problems: the transload bottleneck. Every year, billions are lost transferring cargo between ground and air transport. We believe the solution isn't faster handling — it's eliminating the transfer entirely.
The KS450 is our answer. By engineering an aircraft that carries cargo through the entire journey in a single, sealed module, we've created a vehicle that doesn't just fly cargo — it removes the transload bottleneck entirely. The specifics of how cargo moves between ground and air are proprietary. The outcome is not: no transloading. No handling. No compromise.
Rello Aerotech is developing the KS450 aircraft and engaging with logistics partners and institutional investors to bring the KS450 to certification — and ultimately, to redefine how the world moves heavy cargo by air.
The KS450 stands alone. There is currently no aircraft — available to purchase or in known development — that combines heavy-lift eVTOL capability with a no-transload modular pod system. The KS450 occupies this category entirely by itself.
