In a defining moment for India's aerospace ambitions, Sarla Aviation has commenced ground testing for its half-scale eVTOL demonstrator, Sylla SYL-X1, at the company's Bengaluru test facility.

With a 7.5-metre wingspan, SYL-X1 represents the largest and most advanced private eVTOL demonstrator of its kind currently under development in India. Achieved in approximately nine months of development and at a fraction of the capital typically required for comparable global programmes, the milestone marks a level of engineering scale, execution speed and systems maturity not previously demonstrated by a private aerospace company in the country.

With ground testing now underway, Sarla Aviation's air taxi programme enters its core validation phase, moving decisively beyond digital concepts and laboratory-scale experimentation into real aircraft-scale testing. The current demonstrator is a functional sub-scale aircraft, purpose-built to validate structural behaviour, propulsion integration and system-level safety architecture at meaningful scale. Unlike academic prototypes or small RC-scale platforms, SYL-X1 is designed with certification intent from the outset, forming a direct bridge toward Sarla Aviation's 15-meter wingspan full-scale six-seater Shunya eVTOL aircraft.

Commenting on the milestone, Rakesh Gaonkar, co-founder and CTO, Sarla Aviation, says: “This milestone reflects what's possible when globally experienced Indian engineering teams build with rigour, patience and world-class standards. Our focus has never been on being first, but on building to last, on creating an aviation giant.

“We are building something India can be proud of: a platform that can be certified, produced and safely operated, designed and owned entirely in India. Our goal is to take this new era of aviation technology across the finish line for India and bring it home.”

This achievement places India among a small group of nations actively developing next-generation vertical flight systems at industrial scale. The challenge extended far beyond aircraft design alone, encompassing the creation of a certification-aligned flight-test ecosystem, navigation of India's still-emerging aerospace supply chain and the scaling of the organisation from two founders to a team of nearly 70 engineers within a single development cycle.

During the same period, Sarla Aviation also delivered a full-scale static aircraft for national showcase at Bharat Mobility, while strengthening its long-term execution capability by raising USD 13 million in total funding.

Built entirely in India to global aerospace standards, the SYL-X1 demonstrator reflects Sarla Aviation's focus on execution, endurance and scalability. The company's technology roadmap targets helicopter-class mission endurance, while fundamentally reducing cost, operational complexity and safety trade-offs through electric propulsion and integrated systems design.

As India's advanced air mobility ecosystem begins to take shape, long-term success will be determined not by early announcements, but by the ability to execute through certification, production and sustained operations. In this context, Sarla Aviation brings together one of the most experienced private eVTOL teams in the country, the largest private demonstrator at this stage of development and a rare synthesis of global aerospace expertise with Indian engineering execution.

Together, these foundations position Sarla Aviation to move decisively beyond demonstration milestones and toward delivering operational, certified aircraft at scale, built in India, for India and for the world.
