The UDI U818A Quadcopter is one of the most popular entry-level drones on the market. The device can last for roughly 10 minutes on a full charge, and has the ability to capture video. However, the device isn't without its issues, and you can encounter problems with pairing, calibrating the device, loose batteries, and the camera capturing video. Working through these problems on your own doesn't just allow you to save money, but you'll also learn more about the technology while you're doing it.

Controller Not Working

  • The biggest cause for this has to do with the batteries. Try replacing the batteries in the event that they were low on juice.
  • Remote the battery cover on the back of the controller and make sure that the batteries are properly seated in their respective slots. Maybe someone picked the remote controller up and jostled it, or maybe the batteries were shaken loose when you put the controller in your vehicle to take it out somewhere, but there are a number of things that can happen to cause batteries to pop loose.
  • If you're certain the batteries are good, and even thought they may be seated properly, remove the batteries, wipe any dirt away from the connectors and put them back in to see if that resolves the issue.

Drone Won't Pair with Remote Controller

  • Ensure that both the UDI drone and the remote control are next to each other. Power both devices down, and then start them back up. Sometimes that approach helps both devices recognize each other when there may be other devices nearby that are causing interference.
  • The worst-case scenario is that something became damaged on your drone during a crash that is preventing it from pairing with the remote controller. Take a hard look at the UDI drone to see if you notice any parts that are damaged that may need replaced.
  • Walk through the process to pair the devices one more time. The process of pairing a UDI drone with a remote controller is detailed, and if one of the analog sticks on your remote controller sticks at some point, it can throw the entire process off.

Drone Won't Fly

If you're UDI Quadcopter is just sputtering around appears to be refusing to get off the ground, there are a few options you can try before you go into panic mode:

  • Recalibrate the drone. Poor calibration can result in the propellers not getting to the correct angle to get the device off of the ground.
  • Make sure the propellers are installed properly. Alternatively, make sure that they haven't become adjusted or misaligned as a result of a crash.
  • Finally, try recharging the battery on the drone. It's possible your UDI drone won't get off the ground because it just doesn't have enough power.

Can't See Picture on Smartphone

One of the most interesting aspects of the UDI U818A Quadcopter is that you can see video captured by the drone's camera on your smartphone that's mounted to the remote controller while the drone is flying. Alternatively, if that functionality stops working, it can be incredibly disappointing and frustrating. If your camera stops working there are a couple of things you need to look into:

  • Check the camera on the UDI drone to make sure it's alright. If the camera has been damaged through a crash landing, or perhaps other events, it may not be able to capture anything. You're only option at that point would be to replace the camera.
  • Your drone may be sending a signal back, but there may be something nearby that's preventing that information from being sent back to you smartphone. Make sure to avoid flying near power lines or cell phone towers specifically, but other smaller devices can cause interference as well.
  • Ensure that all of the necessary cables are firmly connected. If there are any loose cables associated with your camera, the feed may not be sending.
