Check the following:
- You can't take off in a flight-restricted airspace.
- Perform the takeoff operation without attaching the propellers to the drone. Try tilting the control lever and see if the motors act differently.
- Calibrate the control sticks using the Airpeak Flight app.
Note: If you can't complete calibration, the control sticks may be broken. Contact the dealer or  Contact the Product Support team .
