Cell phones do not interfere, but WiFi networks do. They operate on the same frequencies that the drones do, and come and go randomly. Note that cell phones can emit 2 kinds of signals - the cell frequencies themselves which allow voice communication and do not interfere with drones, and...

The gimbal motor overload message generally comes from some interference in the free movement of the gimbal. A cable dragging against something, dirt in the mechanism, etc. Gently move the gimbal, with the drone power off, to all is’t possible positions, feeling for any slight resistance. The...

All the DJI drones have some position stability issues when hovering, due to the inherent inaccuracies of both the barometric altimeter and GPS positioning accuracy. GPS accuracy has been improved by adding the newer GPS systems, but accuracy errors are still in the multiple feet area depending...

The tilt, unless you are looking straight down, offsets differently between GE and Litchi. Litchi assumes that you are vertically located over the waypoint looking out at wan ever angle and tilt you have selected. GE assumes that you are looking at that point of interest and backs the...

This may or not be relevant to your problem. Litchi does some interesting things with heading and positioning between waypoints. As you move between them it continuously changes heading and path parameters to smoothly arrive at the next point. Taking into account the position offset from the...

Litchi uses the barometric pressure at the takeoff point as the reference point for all further altitude calculations. It then uses map data to calculate offsets from that point based on the waypoint locations plotted on the map to control the flight. These offsets all shift up or down if you...

The base accuracy of the DJI gps positioning will limit any waypoint repeatability. The best approach would be to do the best you can with that, and post process with Photoshop or Afinity Photo. Both will allow you to create stacks of images and perform alignment in x,y and rotation. They work...

Works fine with p4adv

Microsoft invented exfat to solve this 4 gB problem. DJI has never changed it’s software to take advantage of it. It insists in truncating the files it writes at 4gB. Fortunately on the newer drones post phantom 3, the files are completely continuous and can be flawlessly joined in your video...

Reflow is unlikely to be necessary. It is only required if the original solder joint was never properly soldered. Use a loupe and look at the joint. You should be able to see as older defect by comparing the look of that joint with all the others. Unless you have some skills with...

Yes, no problem. In time they will be overwritten when the drone needs space for the new files. On the other hand, I don’t see any particular benefit, as the files are small, and don’t conflict with the image/video files for space on the SD card.

Focus is achieved by varying the distance between the lens and the Image sensor, controlled by the software tweaking this physical relationship. If the image lens distance cannot be changed due to damage this will cause a permanent focus problem. Changing cables is unlikely. To have anything to...

It all depends on what you want the viewer to experience, like any other video. A fpv itself isn’t all that interesting out of context.

Drones don’t switch into ATTI mode when they loose connection with the rc. ATTI mode is selected only when the gps connection is deemed faulty by the drone computer.

Do the DJI control apps load and run successfully on it? They can be fussy on some versions of the Android operating system.
