Hover Stop Interfaces (HSI) is a project run by a former-Royal Navy aerospace engineer who has a life-long passion for aviation and engineering. His particular interest is in Vertical Take-off and Landing (VTOL) flight and has spent his career working on solving the problems associated with this mode of flight. As a certificated helicopter and airplane pilot, he wanted to make the experience of this type of flight more accessible to everyone.

HSI’s goal is to make the most realistic devices possible. Our products are designed to be produced by hand, in small batches, and, where possible, using the traditional manufacturing processes found in the aerospace industry.
