4.2. Pre-Flight Checks

Before each flight, perform the following checks:

• Ensure the aircraft battery is fully charged and securely connected.
• Check that the remote control batteries are installed and have sufficient power.
• Verify all control surfaces (tail) move freely and correctly in response to remote control inputs.
• Inspect the propellers for any damage or obstructions.
• Confirm the flight area is clear of obstacles and people.

4.3. Take-off

The QF008 can be launched by hand or from the ground (if landing gear is installed).

• Hand Launch: Hold the aircraft firmly, apply full throttle, and gently toss it forward into the wind. Immediately use the right joystick to gain altitude.
• Ground Take-off: Place the aircraft on a smooth, flat surface. Apply full throttle and use the right joystick to steer and lift off once sufficient speed is gained.

4.4. Flight Controls

The 3-channel control system and 6-axis gyroscope provide stable and responsive flight.

• Ascend/Descend: Increase/decrease throttle using the left joystick.
• Turn Left/Right: Move the right joystick left or right.
• Pitch Control: Move the right joystick up or down to control the aircraft's nose angle.
• Gyroscope: The integrated 6-axis gyro automatically stabilizes the aircraft, making it easier for beginners to control.

4.5. Landing

To land the aircraft safely:

1. Approach the landing area at a low altitude and reduced throttle.
2. Gradually decrease throttle and gently pull back on the right joystick to flare the aircraft for a soft landing.
3. Aim for a smooth surface. Landing on grass may cause parts to detach.
