Vertical Aerospace expands flight testing with second VX4 prototype

🔑 Enhanced Key Takeaways

•The second VX4 prototype's maiden piloted flight on June 5, 2026, positions it as the final new aircraft before a Critical Design Review that will finalize the certifiable design of its Valo air taxi.
•Vertical Aerospace achieved a full two-way piloted transition flight with its VX4 prototype in April 2026, making it only the second company globally to accomplish this maneuver in a full-scale tiltrotor eVTOL.
•The company secured $850 million in new funding in April 2026, including $250 million from Yorkville Advisors and $500 million in credit facilities, providing significant capital for its certification path.
•Vertical Aerospace is targeting type certification for the VX4/Valo by the end of 2028 with both the UK Civil Aviation Authority (CAA) and the European Union Aviation Safety Agency (EASA).
•The VX4's airframe will be manufactured by Aciturri using high-performance composite and adhesive materials from Syensqo, with other key partners including Honeywell for flight control systems and E-One Moli Energy for battery cells.

🛠️ Technical Deep Dive

Propulsion System: Features a fixed-wing configuration with four forward-tilting propellers for vertical and cruise flight, and some sources indicate eight electric motors, with four tilting at the front and four rear propellers dedicated to vertical lift.
Passenger Capacity: Designed for one pilot and four passengers, with the production-ready Valo variant accommodating four to six passengers.
Performance Metrics: Projected top speed of up to 200 mph (322 km/h), a cruise speed of 150 mph (241 km/h), and a range exceeding 100 miles (160 km).
Acoustic Profile: Engineered to be near silent in flight, reportedly 30 times quieter than comparable helicopters, with a noise level around 65 dB.
Structural Materials: The streamlined fuselage is constructed from lightweight composite materials, specifically high-performance composite and adhesive materials from Syensqo, and a carbon composite fuselage co-developed with Leonardo.
Battery Technology: Utilizes an all-electric powertrain with rapid recharge capability, featuring high-power cylindrical lithium-ion cells supplied through a partnership with E-One Moli Energy, and a proprietary battery pack design. The Valo design incorporates a liquid-cooled, under-floor 700-volt battery system, reducing battery weight by approximately 20%.
Avionics and Control: Integrates cutting-edge avionics and flight control systems, including fly-by-wire technology with redundant systems, and a compact Fly-by-Wire system provided by Honeywell Aerospace.
Safety Features: Incorporates multiple redundancies in the propulsion system and a ballistic recovery system, aiming for certification at commercial airline safety levels by EASA.
Dimensions (VX4): Measures approximately 35 feet in length, with a 40-foot wingspan and a 10-foot height, and a maximum takeoff weight exceeding 5,000 lbs.
Hybrid-Electric Variant: A hybrid propulsion system is under development, targeting a significantly extended range of up to 1,000 miles and an 1,100 kg payload, expanding its mission flexibility.

Accelerated certification for urban air mobility.

Doubling the test fleet and achieving complex flight milestones like two-way transition flights significantly de-risks and speeds up the regulatory approval process for the VX4.

Expansion into regional and defense markets.

The development of a hybrid-electric VX4 variant with a 1,000-mile range and higher payload capacity broadens its applicability beyond urban air mobility to include regional connectivity, defense, logistics, and air ambulance services.

Increased competition and potential market consolidation in the eVTOL sector.

The substantial new funding secured by Vertical Aerospace positions it more strongly against well-funded competitors, intensifying the race for market share and potentially leading to consolidation among less capitalized players.
