Your drone won’t take off? Here’s what to check first
As a drone operator, one of the most frustrating things that can happen aside from a crash is when your drone won’t even take off from the landing pad. It doesn’t matter if you’re flying just for fun or for hire – these flukes can happen to anyone at any time, but there are a few different troubleshooting steps you can take to find out why it’s happening and attempt a quick fix.

Drone won’t take off? Try this…
GPS connection
One of the most common reasons why a drone won’t take off is that the drone’s internal GPS hardware is having a hard time connecting to GPS satellites. For safety reasons, many drone manufacturers require a connection to a certain number of GPS satellites to maximize positioning accuracy and reduce accidents.
You can check the display on your computer, whether that’s a handheld dedicated controller or your smartphone with an app, to see how many GPS satellite you’re connected to. Some manufacturers require at least 6-8 satellites, but some drones also have an override mode that’s less safe to operate in.
If you find that you aren’t connected to any satellites, or you have a low number of connections, try waiting a little longer or restarting the drone. You should also make sure you have an unobstructed view of the sky, as tree canopies and even ceilings can block a GPS satellite connection.
Batteries
Another reason that a drone won’t take off is because the user has forgotten to charge their battery or there’s a seating problem. Modern drones come equipped with safety features that force it to return to home when the battery level gets too low, and then they won’t take off again until the battery receives a charge.
When the battery level gets too low, the propeller motors can’t spin the propellers fast enough to generate lifting thrust. Drone batteries tend to exhibit reduced voltage below 20% charge, so if your battery level is too low, consider charging to swapping out the battery for a fully charged one and see if it fixes the problem.
If battery charge isn’t the issue, then it could be that the battery isn’t fully seated. This has happened to me before where I’d insert a new battery, but I was too thrilled to fly in that moment that I didn’t listen for an audible ‘click’ when it seated. When it didn’t take off, I simply pressed harder on the battery to insert it until I felt the tactile click, and all was well.
Folded arms
Sometimes in the heat of the moment, you may put the battery into your drone and then someone starts talking to you and you forget to fully unfold your drone’s propeller arms. When this happens, the drone will not fly.
Double check to make sure you’ve fully un-folded the drone’s propeller arms before you launch your drone, as a failure to do so will inhibit your ability to take off.
Propeller blockages
A common issue for drone operators, especially in grassy or tree-filled environments is for ground debris to block the drone’s propellers.
We always recommend using a landing pad, such as the Hoodman weighted landing pad, since it gives your drone a smooth and safe surface to take off from and land on. But if you can’t afford one and you’re using the bare ground, it’s possible that foliage, sticks, or other obstructions could be impeding your drone motors’ ability to spin the propellers, and this will prevent takeoff.
If you find this to be the case, remove any blockages or try taking off from a smoother surface, such as a sidewalk or parking lot.
Pending software updates
Drones are small computers, and so they frequently receive software updates for critical components that ensure a safe flight operation. In some cases, manufacturers consider some software updates to be so critical that they won’t let you fly the drone until the software update completes.
You can usually check to see if you have any pending software updates from your handheld controller display or from your smartphone with an app, and if there are any, this could be the reason for non-flight.
Install any pending software updates and see if the drone takes off afterward.
Flight restrictions
Despite being thought of as toys, the Federal Aviation Administration (FAA) considers drones to be small aircraft, and operators are expected to follow the rules of the road (or the rules of the sky, in this case). This includes making sure that you aren’t taking off in No-Fly Zones, controlled airspace, or during an active NOTAM that restricts flight in your area for a special reason.
Many manufacturers try to automate this process by locking flight in areas where flight would otherwise be restricted, but it’s not a fool-proof system and it’s the remote pilot’s responsibility to keep an eye on these before taking off. You can normally see any restrictions from the drone’s app, but an even better resource is a website called SkyVector, which shows all flight resections in real time.
If you find that you’re attempting to operate in a restricted region, then try taking your drone somewhere else and see if this fixes the problem.
Controller connectivity
On occasion, the handheld remote control can lose its connection with the drone, and when this happens, all your input isn’t being sent to the drone to let it know to take off.
Be sure to always check the active connection status on your handheld remote control or smartphone with app to make sure that you have an active connection with the drone. It will usually give you an indicator of signal strength.
Always operate your drone from a relatively close distance unless you absolutely can’t. Since visual line of sight is so important for drone operations, this should be a given, but if you’re flying without visual line of sight because you have an FAA waiver, then this could be the issue.
Hardware failure
In extreme cases, failure of a propeller motor could be to blame. This can happen on a drone with several hours of use and is less common on a brand-new system, but like anything else, drone motors eventually burn out and need to be replaced.
Another possibility is that wind or rain has damaged your drone’s propeller motor(s), and if this happens, then it doesn’t matter how old or new your drone is.
You can usually check a propeller motor for issues. If you try to spin the propellers manually and you feel cracking or resistance, then you know there could be debris blocking its function. If it spins normally by hand but doesn’t spin on command with the controller, suspect a faulty motor. The manufacturer’s handheld controller or smartphone app may even alert you to an error via an error message in the app.
Wrapping up
Issues that prevent your drone from taking flight are never fun, and they can often spoil a planned drone flight. Fortunately, these are often easy to troubleshoot and require just a little patience and additional pre-flight checklist care to prevent.
