working range (2 - 3.5 m). Refer to the Altitude Stabilization System (p. 30) for details. Then

Return-to-Home (RTH)
RTH: The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home
Point.
Home Point: If the GPS signal is strong enough (GPS count ≥ 6) after powering on for 30
seconds, then the launching location of the aircraft will be recorded as the Home Point.
When using System Data Protection, the Home Point will not be updated if you restart the
aircraft after changing the battery.
There are two events that will trigger RTH procedure: Smart RTH and Failsafe RTH.
Smart RTH
Use the RTH button on the remote controller (see RTH Button on p. 21 for more details) when GPS
is available to enable Smart RTH. Press and hold the RTH button to enable Smart RTH. The same
RTH procedure is applied to both Smart RTH and Failsafe RTH. With Smart RTH, you may control
the aircraft’s orientation to avoid collisions when it is returning to the Home Point. To exit Smart RTH,
regain control manually. Refer to How to Regain Control (p. 33) for more details.
It is not possible to start the RTH procedure by pressing the RTH button when the Flight
Mode is toggled to the “M” position.
Failsafe RTH
The Failsafe RTH must be enabled in the MG-1 Assistant. If Failsafe RTH is not enabled,
the aircraft will hover in place when the remote controller signal is lost.
Failsafe RTH is activated automatically if the remote controller signal is lost for more than 3 seconds
provided that the Home Point has been successfully recorded and the compass is working normally. The
operator can interrupt the Return-to-Home procedure and regain control over the aircraft if the remote
controller signal is recovered. Refer to How to Regain Control (p. 33) for details.
