Arm + Takeoff

1. Set Manual Flight Mode​

Select LOITER or ALTHOLD flight mode.

⚠️
  • If a good GPS fix is available at the takeoff location, it is always recommended to use LOITER flight mode for takeoff.
  • ALTHOLD flight mode is reserved for scenarios with poor GPS reception, such as taking off in a deep valley or when there is limited visibility of the sky.

2. Arming the motors​

  • Move the throttle stick fully down and then fully to the right for 3 seconds. You will hear a long beep from the motors, and they will start rotating at low RPM.
⚠️

If no control inputs are made within 5 seconds after landing, the drone will automatically disarm the motors.

3. Observe the propellers​

After moving the throttle stick, the propellers should begin to rotate slightly. However, if a PreARM message appears, this indicates a safety mechanism preventing the motors from starting.

⚠️
In case of a PreARM message:
  • Determine the cause of the message.
  • Take the necessary corrective actions, see Troubleshooting guide.

4. Raise the Throttle to 50%​

Still with the throttle stick down, move the stick to the center, and then release it until its rest position in the middle. At this point you will notice that the propellers will spin faster, but the Drone will still not ascend.

5. Takeoff​

Once the Drone is armed and the throttle stick is in the middle, follow these steps for a safe takeoff:

  1. Move the throttle lever until it reaches approximately 75%.

  2. As soon as the drone reaches a height of 5 to 10 meters, return the throttle stick to the middle.

6. Confirm the aircraft is stable and reacting correctly to stick inputs.​

It is recommended to make small Roll, Pitch, and Yaw inputs and observe the drone's response. While not mandatory for every flight, this can be helpful in assessing the system's behavior.

⚠️

In Loiter flight mode, the Drone is expected to maintain its X, Y, and Z position.

7. Observe the battery voltage has not dropped significantly under load.​

Check the battery voltage drop under load.

⚠️

This is a well known indicator that the batteries are old or have reached the end of their lifespan.
