Useful for flight schools, aircraft rentals, insurance providers, and research and development.

What's New

  • Updated enclosure and mounting: embossed labels, new 6-32 mounting pattern on the base, with an optional CNC aluminum adapter that provides a standard 1/4-20 tripod mount.
  • Improved internal layout: refined internal board stack for better serviceability and future options.
  • Battery updated: earlier OnFlight Hubs provided 13+ hours. Current units use a slightly smaller battery and provide 8+ hours, while maintaining the same data quality and features.

What Our Customers are Saying


"Chukar flats is a very short, uncharted strip in the John Day River canyon. I took my 180 in there for the first time yesterday, and brought the OnFlight Hub. I just downloaded it this afternoon, and it is the coolest f***ing thing to have this data and this display format! Thank you!"
