DJI drones are known for their ease of use, high-quality cameras, and impressive flight capabilities. However, even with these advanced machines, issues can arise that prevent them from taking off. Frustrated pilots around the world have asked the same question: “Why won’t my DJI drone take off?” In this article, we’ll delve into the most common reasons behind this problem and provide solutions to get your drone airborne again.
Pre-Flight Checks: The First Line of Defense
Before we dive into the possible causes, it’s essential to ensure you’ve completed the necessary pre-flight checks. DJI drones have built-in safety features that prevent takeoff if certain conditions aren’t met. Make sure to:
- Update your drone’s firmware and app to the latest version
- Check the battery level and ensure it’s above the minimum required threshold (usually 30%)
- Verify the drone’s propellers are securely attached and free of damage
- Calibrate the drone’s compass and accelerometer (if necessary)
- Conduct a visual inspection of the aircraft and surrounding area for any obstacles or hazards
Common Causes of Takeoff Issues
Now that we’ve covered the pre-flight checks, let’s explore the most common reasons why your DJI drone might not be taking off:
1. GPS Signal Issues
A weak or unstable GPS signal can prevent your drone from taking off. This is because the drone relies on GPS data to determine its location, altitude, and velocity. To resolve GPS signal issues:
- Move to an open area with a clear view of the sky
- Check for nearby tall buildings, trees, or other structures that might be interfering with the signal
- Restart the drone and try again
- Update your drone’s firmware to the latest version, as newer versions often improve GPS performance
2. Obstacles in the Takeoff Zone
Your drone’s obstacle avoidance system might be triggered, preventing takeoff. Ensure the surrounding area is clear of obstacles, including:
- People or animals
- Trees, branches, or other overhead obstructions
- Power lines, buildings, or other structures
- Other drones or aircraft
3. Motor or Propeller Issues
Faulty or damaged motors or propellers can prevent takeoff. Inspect your drone’s motors and propellers for signs of wear or damage, such as:
- Scorched or burned components
- Loosely attached propellers
- Cracked or broken propeller blades
- Unusual noises or vibrations during motor operation
If you suspect motor or propeller issues, contact DJI support or a authorized repair center for assistance.
4. Flight Mode Conflicts
DJI drones offer various flight modes, each with its own set of restrictions. Ensure you’re in the correct flight mode for your intended usage:
- Sport mode: Enables high-speed flight, but may not work in areas with restricted airspaces
- Normal mode: Suitable for most users, offering a balance between speed and obstacle avoidance
- ActiveTrack mode: Designed for tracking subjects, but might not work in areas with strong winds or obstacles
- Tripod mode: Limits speed and agility, ideal for cinematic shots or precise control
Switch to a different flight mode to see if it resolves the issue.
5. Compass Calibration Issues
An incorrectly calibrated compass can cause takeoff problems. Try recalibrating the compass by following these steps:
- Go to a open area with minimal interference (away from metal objects, power lines, and other sources of magnetism)
- Place the drone on a level surface
- Open the DJI GO app and access the compass calibration menu
- Follow the on-screen instructions to complete the calibration process
Troubleshooting Beyond the Basics
If you’ve checked the above causes and your drone still won’t take off, it’s time to dig deeper.
1. Drone and Remote Controller Connection Issues
Weak or lost connections between the drone and remote controller can prevent takeoff. Try:
- Restarting the drone and remote controller
- Moving closer to the drone to improve signal strength
- Updating the remote controller’s firmware (if possible)
- Resetting the remote controller to its factory settings
2. Environmental Factors
Inclement weather, air traffic control restrictions, or other environmental factors might be hindering takeoff. Be mindful of:
- Weather conditions like strong winds, heavy rain, or extreme temperatures
- Air traffic control restrictions, such as No-Fly Zones or temporary flight restrictions
- Magnetic interference from nearby sources, like power lines or metal structures
3. Firmware and Software Issues
Corrupted or outdated firmware and software can cause takeoff problems. Try:
- Updating the drone’s firmware to the latest version
- Reinstalling the DJI GO app
- Performing a factory reset on the drone (if necessary)

Why does my drone say it’s not receiving a GPS signal?
A GPS signal is required for a safe and stable flight. Make sure you are in an open area with a clear view of the sky, away from tall buildings, trees, or other structures that might interfere with the signal. Try restarting your drone and controller, then wait for a few minutes to allow the drone to acquire a GPS lock.
If you’ve checked all of the above and your drone still won’t take off, try updating your drone’s firmware to the latest version.sometimes, outdated software can cause issues with GPS reception. Additionally, check for any nearby sources of interference, such as other drones, Wi-Fi routers, or microwaves, and move them away from your drone.
Why is my drone’s propellers not spinning?
If your drone’s propellers are not spinning, it could be due to a variety of reasons. First, check that the propellers are properly attached to the motor and that there are no obstructions blocking them. Also, make sure that the drone is on a flat and level surface, as tilting can prevent the propellers from spinning.
If the propellers are properly attached and the drone is on a level surface, try recalibrating the drone’s compass or IMU (Inertial Measurement Unit). Sometimes, a faulty calibration can prevent the propellers from spinning. Additionally, check the drone’s motor for any signs of damage or wear, as a faulty motor can also prevent the propellers from spinning.
Why does my drone say it’s in “mode 1” or “mode 2” and won’t take off?
If your drone is stuck in “mode 1” or “mode 2” and won’t take off, it’s likely due to a faulty or incomplete calibration process. Mode 1 and Mode 2 are usually related to the drone’s flight mode or calibration mode. Try restarting the calibration process or resetting the drone to its factory settings.
To do this, refer to your drone’s user manual or online documentation for instructions on how to reset the drone. If you’re still having trouble, try contacting DJI’s customer support for further assistance. They may be able to remotley access your drone and resolve the issue.
Why is my drone’s battery not charging?
If your drone’s battery is not charging, try checking the charger and cable for any signs of damage or wear. Also, make sure that the charger is properly plugged into a working outlet and that the drone’s battery is properly inserted into the charger.
If the charger and cable appear to be in good condition, try resetting the battery or charger. Some drones have a reset button on the charger or battery, while others may require a specific sequence of button presses. Refer to your drone’s user manual or online documentation for instructions on how to reset the battery or charger.
Why is my drone’s remote control not working?
If your drone’s remote control is not working, try restarting the controller and drone, then re-pair them. Make sure that the controller is properly paired with the drone and that the batteries in the controller are not dead.
If the controller is still not working, try updating its firmware to the latest version. Sometimes, outdated software can cause issues with the controller. Additionally, check for any signs of physical damage or wear on the controller, such as broken buttons or a damaged antenna.
Why does my drone keep saying it needs to be updated, but the update fails?
If your drone keeps saying it needs to be updated, but the update fails, try restarting the update process or resetting the drone. Sometimes, a faulty update can cause issues with the drone’s software.
If the update still fails, try updating the drone through a different method, such as using a computer or mobile device instead of the drone’s remote control. Additionally, check that your drone is connected to a stable internet connection and that the update files are not corrupted.
