There are many things that don’t work as well at high altitude. Many of these don’t apply to the MagArrow such as LCDs, can type electrolytic capacitors, hard drives, sealed keyboards, and High Voltage flashover points.

What could possibly be an issue are the LiPo batteries, thermal cooling reduction at lower pressures, and the sealed MagArrow case.

  • MagArrow Case: While the body of the MagArrow is sealed tight, it is not sealed enough to puff out or get crushed with altitude changes. This hasn’t been tested.
  • LiPo Batteries: These are not altitude rated. The failure mode is shorted cells and fire.
  • Thermal Cooling: This could be measured in a pressure chamber using the internal temperature monitor diodes. We would have to rent time in the chamber to do the measurement. We might also make a stab at calculating the temperature increase. 30,000 feet is about 3 PSIA compared to 14 PSIA at sea level.

There is no altitude restriction on the MagArrow, but flying at high altitudes is taken at the users risk.
