The Zapata Flyboard Air is manufactured by Zapata Racing. Top speed is over 90 mph with a ceiling of 10,000 feet. It will fly for approximately 10 minutes before the backpack fuel tank needs to be replaced.
If you would like to purchase one of these boards for personal use you are out of luck. The Flyboard Air is currently not available for recreational use because of lack of government approval. When they are approved, they will set you back $250,000 per board.
