If you are downloading firmware and the internet connection is to weak it can lead to interrupted problems and unsuccessful downloads. If this happens, delete it and download again the newest version.

The role of the firmware is to connect the drone hardware with the operating system of the drone. If the firmware is corrupted and you install it on your Phantom 3, there may be a sudden RC signal loss.

Detailed Review Of The RC and Phantom 3

Before each use of the drone it is necessary to see if your quadcopter has any cracks after a hard landing. What does this have to do with Phantom 3 RC signal loss? These checks are important because you can determine whether there is internal damage to the receiver or the transmitter of the RC.

Also, the drone and RC need to be kept clean at all times. Sometimes a lot of dust if it accumulates on a drone can block the signal during flight (it is rare, but can happen). Also, make sure your DJI Phantom 3 has no bent or warped propellers. Maintain your drone regularly to keep it in good condition and always in ready to fly mode.

Boost Your Phantom 3 RC Signal

DJI Phantom 3 is using the amplified Wi-Fi signal to communicate from your controller to the drone itself. The problem with that connection is that you’re only have the range of 1km on the clear day. If you want to increase the signal range on your Phantom 3, a simple range booster can increase the controllers range on your remote controller.

The range booster works in such a way that the remote controller will focus the signal on your Phantom 3 and increase the range. By that you will always have the stronger signal in all directions. This solution will cost you a little bit, but it’s definitely worth if you want to increase a signal on your Phantom 3 and it’s called SKYREAT Copper Parabolic Antenna Range Booster. Just attach this to your controller and will increase your RC signal.

The Phantom 3 RC Calibration Problem

Sometimes the problem with the weak controller signal can be in the RC. If your RC is not calibrated regularly, it might happen that your RC signal loss will occur on Phantom 3. Also, if during flight you notice that your Phantom 3 is flying erratically, you need to perform a calibration on your RC as soon as possible.

  1. Power Off the DJI Phantom 3. Turn on the Remote Controller and open the DJI GO app on your device.
  2. Enter the camera view button and then tap the “Remote Controller” icon.
  3. Next step is to choose the “RC Calibration” and then tap “Calibrate”.
  4. Now you have to move the throttle stick according to the instructions shown in the app. Repeat it several times and ensure that the throttle stick can go through the maximum and minimum path.
  5. Turn the dial according to the instruction given by the app and repeat it several times. After that you just need to tap “Finish” and that is it.

Landing: If 3 seconds after the RC signal is lost, the DJI Phantom 3 will land on the ground safely.

Hover: 3 seconds after the RC signal is lost, the Phantom 3 automatically hovers in the air first, then lands on the ground when the battery level gets low.

Return-to-Home: Select “Failsafe Mode”. Enter a safe RTH altitude. For example, 80m. If the current altitude of the Phantom 3 is 80m or higher the drone will horizontally return home at the current altitude. If it is lower than 80m the Phantom 3 will ascend to 80m and then return home horizontally.
