OnFlight Hub is in stock and ships within 1 - 2 business days. The CNC aluminum 1/4-20 adapter is in production; for domestic orders, if you purchase both, we’ll ship the Hub now and the adapter in late December or early January at no additional cost.


OnFlight Hub is the premier flight data logger in the OnFlight family from BFS - and the first of its kind. Ideal for all pilots: student, CFI, backcountry, aerobatic, ultralight, experimental, and anyone who'd enjoy reviewing their previous flights and performance. Useful for flight schools, aircraft rentals, insurance providers, and research and development.

What's New

  • Video summary: short video summarizing the updates to version 2.
  • 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!"
