In any of the following low battery situations, the fail-safe will be activated.
A. The aircraft will continuously calculate the battery level required to the return point. When the
battery level reaches the maximum level required to the return point, The fail-safe will be
activated and start the return process.
B. When the aircraft battery level reaches the set threshold (25% by default), you will receive one
low battery alarm, and the fail-safe will be activated to start the auto return of aircraft. If you
recover the control on your aircraft, when the battery level reaches 15%, you will receive one
serious low battery alarm, and the aircraft will automatically land on the spot. In emergency, you
will need to manually make the aircraft fly to the nearest safe landing point.
Precise landing
Dragonfish Lite integrates high-precision RTK modules and conventional GNSS modules to
provide centimeter-level precise positioning. The aircraft scans and matches terrain features. If the
current topography is matched with that at the take-off point, it will land as close to the take-off
point as possible.
Important
The aircraft will record the take-off point as the default return point.
Select an open and well-lit area (such as grass lawn) as the take-off point.
When the aircraft is ready for landing, it is necessary to ensure that the take-off environment
has no change.
