As soon as Elios is turned on, it starts to record information such as sensor values, camera settings, and even controller inputs from the pilot. This data allows Flyability engineers to carefully analyze malfunctions should they occur. The data log also allows you to retrieve telemetry data while post processing your mission using the Flyability Inspector software. This information is saved on the LOG SD card, flight is not possible with this card removed.
The video recording starts as soon as Elios is armed and stops when Elios is disarmed, provided that the correct SD card is inserted.
