If someone could test this please. The apk can be found here. When someone has version 1.1.2 running and the map is working during flight, I would appreciate it very much to get the resource file. It can be found in the folder /Android/obb/dji.go.v5. Thanks a lot!

Anyone still using version 1.1.2 of DJI Fly app? Is it working normally for you? I was using it from time to time for my fcc mini in Europe 2 years ago but after a long drone break for myself as it seems there is a a problem with the map at the moment. It shows just a blank page and no drone...

The additonal gain due to multireflectors is in my opinion quite low. More effective is a streched design like my long version of the 7-element yagi. This brings up to 2 dBi on top. ?

The antenna is designed for channel 7 (2442 MHz).

The question that I´m asking myself is how could a short contact with water cause a damage on the mainboard? From the outside it looks perfect but I guess that some components are very sensitive against minimal currents which could be transmitted over water. It was no salt water btw. Which...

Thanks for all the answers! It can be that it doesn´t have to do anything with the loss of weight but then it was in my opinion caused by a problem with the VPS. As described I´ve been flying over a red bedsheet when the bird suddenly lost the landing gear and started to rise. Perhaps the...

I´ve flown a couple of times in this room without any problems but the only thing this time was different was that I flew over a red bedsheet. There the Mini lost the landing gear and started to loose control. Maybe the infrared light from the VPS couldn´t be seen by the cam due to the red...

Thanks for the hint. I´ve attached the log. The floor was very even in color and shape and it could be that the downward cam couldn´t get a good reference picture.

I´ve lost one of four landings gears (3d printed add-ons) during an indoor testflight and the consequence has been that the drone has started climbing and couldn´t be stopped via remote control until it crashed with the ceiling. The weight of one landing gear is about 5g. Now I´m trying to find...

It has turned out that it was a defective mainboard. I swapped it today with another one and the drone works normal. Now I facing the problem that I got the two gimbal error messages (40011, 40021), which are well known and I´ve learned that I have to live with them, because only DJI can pair...

Aluminium or copper doesn´t make a big difference. Copper is a little bit better but only if its not oxidized, which goes fast in a few weeks. Steel is much worse and for this purpose not a good choice. Better would be silver but I guess nobody would like to pay for that ;) Pipes would be no...

Thanks for the hint. Perhaps I will try it the next days how the bird behaves without gimbal and cam connected. But my assumption is a problem with the ESC because charging is not possible either.

Hi, I bought a defective Mini with a strange error. The seller said that it could have been in contact with water in a bag. From the outside and the inside the bird looks normal. All ribbon cables are tight and glued. Here are the symptoms: - When the drone is off and you push the power...

I would say the more precise the better. My digital caliper is able to measure 1/100 mm but I have to admit that its hard to trim the rods so exact. For 2.4 GHz I think 1/10 mm is enough. The distances are in relation to the middle of the plasic case. The board with the antenna is placed quite...

There is enough transmission power to feed any antenna. ;) It all depends on the correct dimensions. Here are the parameters for my 7-Element standard version (2.4G) build with 3 mm alu rods. Distances from the middle of the original antenna: R=-24 mm D1=10 mm D2=32 mm D3=58 mm D4=89 mm...
