Operating Your Helicopter
Basic Controls
The SYMA S107G is a 3-channel RC helicopter, offering the following movements:
- Throttle (Left Stick Up/Down): Controls the helicopter's altitude (ascend/descend).
- Yaw (Left Stick Left/Right): Rotates the helicopter left or right on its vertical axis.
- Forward/Backward (Right Stick Up/Down): Moves the helicopter forward or backward.
- Left/Right Turn (Right Stick Left/Right): Tilts the helicopter to move left or right.

Indoor Flight Only
Due to its infrared control system and lightweight design, the SYMA S107G is strictly for indoor use. Outdoor conditions, even light breezes, can cause loss of control. Avoid flying near open windows, fans, or air conditioning vents.
Flight Tips
- Smooth Movements: Use gentle and smooth inputs on the joysticks for better control, especially with the throttle.
- Trim Adjustment: If the helicopter drifts or rotates on its own, use the trim buttons on the remote control to correct its flight path. Adjust the trim in the opposite direction of the drift.
- Clear Area: Ensure you have a clear, open indoor space free from obstacles, pets, and people before flying.
- Landing: Reduce throttle slowly to land gently. Avoid sudden drops.
