5. Operating Instructions

5.1 Basic Controls

5.2 Take-off and Landing

• Take-off: After pairing, slowly push the left joystick (throttle) upwards. The helicopter will ascend. Adjust the throttle to maintain desired altitude.
• Landing: Slowly pull the left joystick (throttle) downwards. The helicopter will descend. Reduce throttle completely upon landing.

5.3 Altitude Hold Function

The SYMA S39 features an altitude hold function. Once the helicopter reaches a desired height, release the left joystick (throttle). The helicopter will automatically maintain its current altitude, allowing you to focus on directional control.

Image: The Altitude Hold function allows the helicopter to maintain a stable height without constant throttle input.

5.4 High/Low Speed Mode

The remote control has a button to switch between High and Low speed modes. Low speed is recommended for beginners and indoor flight, while High speed offers more responsiveness for experienced pilots or outdoor flight in calm conditions.

5.5 Trim Adjustment

If the helicopter drifts in a certain direction without input, use the trim buttons on the remote control to correct its flight path. Adjust the trim in the opposite direction of the drift until the helicopter hovers stably.

5.6 Non-Interference Technology

The SYMA S39 utilizes 2.4GHz radio frequency technology, which allows multiple helicopters to be flown simultaneously without interference, provided they are properly paired to their respective remotes.
