Volandoo BLE Vario

Notes:

A 500mAh battery will give you about 7 hours of flight time when fully charged. I recommend using a 1000mAh battery instead

The vario will try to connect to another device but shut down automatically if it can't connect within 6 seconds. Once connected, it will shut down when disconnected.

Once shut down it will wake up again when the button is pressed. The battery will last a long time when the vario is shut down. But just in case, charge it before going flying.
