Figure 3: Key flight functions including Headless Mode and One-Click Takeoff/Landing.
5.2ヘッドレスモード
In Headless Mode, the aircraft's orientation is locked to the remote control's orientation at the time of activation. This means pushing the right joystick forward will always make the aircraft fly away from you, regardless of which way the front of the aircraft is facing.
- To activate Headless Mode, press the Headless Mode button on the remote control. The aircraft's lights will flash to indicate activation.
- To exit Headless Mode, press the Headless Mode button again.
5.3 高度維持
The Altitude Hold function allows the aircraft to maintain a stable altitude without constant throttle input. This makes it easier to control and capture stable photos/videos.
