SIMREX 2799-GPS Instruction Manual

Flight Safety Precautions

Before flying, please familiarize yourself with the aircraft and safety precautions.

• This is not a toy and is not suitable for children under 14 years old.
• Do not touch the rotating propeller, as it may cause injury.
• Maintain a safe distance during the first flight to avoid damage from improper operation.
• Do not fly near crowds.
• Do not fly in bad weather.
• Keep the aircraft in sight and away from obstacles, high-voltage lines, trees, and water bodies.
• Do not fly in restricted no-fly zones or areas violating relevant laws.
• Do not fly within the Arctic Circle.
• Avoid flying in areas with complex electromagnetic environments, such as near base stations or transmission towers, as this can weaken GPS signals or disturb remote control operation.

Caveat

Keep a safe distance from the high-speed rotating propeller to avoid the risk of injury.

Tip: Videos recorded in SD are best played on a computer.

Headless Mode

• Press the headless mode button to lock the aircraft's takeoff direction. In this mode, the aircraft's orientation is irrelevant; the nose direction is always considered forward.
• Press the button again to exit headless mode.

Note: Do not enter headless mode in a strong magnetic environment.

Remote Control Left and Right Hand Conversion

Press and hold the one-button unlock/landing button, then turn on the remote control power switch to switch between left and right-hand throttle modes. The remote control display will indicate MODE2 (left-hand throttle) or MODE1 (right-hand throttle).

Aircraft Operation

The remote control and aircraft must be successfully matched, and the GPS star search must be completed for safe flight. Press and hold the unlock/landing button until you hear a beep; the aircraft will unlock, and you can then push the throttle up. During flight, long-pressing the unlock/landing button and releasing it will initiate an automatic landing. The motors stop and lock upon landing.

One-Key Return

When the aircraft is more than 20 meters from the takeoff position, press the one-button return button. The rear arm lights will turn bright red. If the aircraft's altitude is below 20 meters, it will ascend to 20 meters before returning. If it's already above 20 meters, it will initiate the return flight directly. The aircraft will hover briefly at the takeoff position before landing. Motors stop automatically after landing.

Important Flight Guidelines

• Fly in open areas with a strong GPS signal.
• Maintain a line of sight with the aircraft.
• Fly below 400 feet (120 meters).
• Avoid flying over or near obstacles, crowds, high-voltage power lines, trees, airports, or bodies of water.
• Do not fly near strong electromagnetic sources like power lines and base stations, as they can affect the compass.
• Do not use the drone in adverse weather conditions such as rain, snow, fog, or wind speeds exceeding 10 m/s (22 mph).
• Stay away from rotating propellers and motors.
• Always read the Safety Guidelines before flight.
• No Fly Zone: Do not fly in restricted areas.

Turn Off GPS Manual Control Mode

If GPS or geomagnetism fails, and the aircraft experiences uncontrolled yaw or rotation, long-press the mode switch button to enter manual control. The GPS icon on the remote control display will turn off, and the aircraft's tail-arm light will turn yellow. The aircraft will enter a fixed-height mode to facilitate manual control for safe landing. Recalibrate the magnetic compass. If the fault persists, contact the dealer.

Starting Your First Flight

1. Place the connected aircraft horizontally on the ground, ensuring the tail faces you and the head faces forward.
2. Simultaneously move the left joystick to the lower-left corner and the right joystick to the lower-right corner to start the motors. To stop the motors in an emergency, move both joysticks to the bottom corners.

Low Electricity Return and Electronic Fence

• The aircraft has an electronic fence with a maximum flying distance of 500 meters and a height of 200 meters before low-voltage protection is engaged.
• Upon entering the first low-voltage state, the aircraft will return to a point within a 50-meter radius and descend to 20 meters. If it remains within the electronic fence, it will not initiate return flight.
• Within the electronic fence, the aircraft can still operate autonomously but cannot enter modes like 'Follow Me,' 'Headless,' or 'Return.'
• When the aircraft enters the secondary low-voltage state within the electronic fence, it will land in place.

Attention: When the aircraft enters low-voltage return flight, land it as soon as possible, even within the electronic fence, to prevent battery over-discharge.

Gyroscope Calibration

1. To correct flight attitude, perform horizontal calibration.
2. Simultaneously move the left and right joysticks to the lower-left corner for approximately 1.5 seconds. The aircraft's four indicator lights will flash rapidly, indicating entry into horizontal calibration. Wait until the lights become solid to confirm successful calibration.

Remote Control Function Indication

Unlock/Landing: Click the unlock button; it turns red, and the aircraft starts idling. Click again to lock and stop movement. After unlocking, press this button to take off; the aircraft automatically climbs to about 1.5 meters and hovers.

One-Key Landing: Press the button indicated by a downward arrow for automatic landing.

One-Key Return: Press this key to return to the takeoff point.

Multi-function Flight Mode: Press the $\square$ button to enter multi-function flight mode. Options include Waypoint Planning, Follow Me, and Points of Interest Surround. Press $\square$ again to exit.

Waypoint Planning Mode: Enter multi-function flight mode, then select waypoint planning. The APP switches to map mode, displaying a waypoint setting dialog. The electronic fence is set with a 120-meter radius from the controller's coordinates; exceeding this distance limits access. Blue dots on the map represent the controller's coordinates, and red dots represent the aircraft's coordinates. Map scale can be adjusted.

Pointing Flight: Click the pointing flight icon ($\bigstar$) to enter this mode. Select a destination on the map and click $\rightarrow$ to send the waypoint command. The aircraft will fly to the pointed waypoint and hover. Click $\bigotimes$ to delete the current waypoint.

Multi-Task Execution: Enter multi-point flight mode. Set multiple waypoints on the APP interface and click $\rightarrow$ to send the command. The aircraft executes waypoints sequentially. After the last waypoint, it returns to the initial planned position. Press $\bigotimes$ to delete the current waypoint.

Special Note:

1. For the first flight, recalibrate the magnetic compass for stable flight.
2. Calibration requires a flat site with the aircraft level to the ground.
3. Keep the aircraft stationary during calibration until it is successful.

Calibration Magnetic Sensor

Long-press the gear button ($\textsf{⚙️}$) until the remote control beeps. The aircraft's rear arm lamp turns red, indicating geomagnetism calibration has begun.

• X-axis Calibration: Rotate the aircraft horizontally 360 degrees. When the rear arm lamp turns green, the X-axis calibration is complete.
• Y-axis Calibration: Rotate the aircraft vertically 360 degrees (head-up). When the rear arm lamp flashes green normally, the Y-axis calibration is complete.

After calibration, the light returns to a slowly flashing green (with a star) or alternates red/green (searching for a star).
