What we're building

A practical vehicle concept for high-efficiency, heavy-lift drones (uncrewed aircraft systems) designed to break the current "lift bottleneck" and deliver greater payload capacity through a clear, safety-first development pathway.
The core objective is to surpass the standard 1:1 payload-to-weight ratio and achieve a major efficiency leap, with clear testability and a manufacturing pathway. The design includes: Maximum Aircraft Weight: 55 lbs (including fuel or batteries).

• Minimum Payload: 110 lbs (at least double its own weight)
• By targeting a 4:1 payload-to-weight ratio, this vehicle aims to redefine standards for heavy-lift drones and demonstrate a transformative leap for the industry
• Advanced materials for lightweight construction
• Efficient propulsion systems for optimal energy use
• Autonomous flight capabilities for safety and reliability
• Scalable manufacturing processes for volume production
