Amazing,  the M2P can't even do 10km.

  

Good place for distance.  Flat and not much interference.

Pretty good considering it was the lower power CE version.

Amazing!!   At the end, did you slow down the speed yourself??

Not my video, just one I came across.

It also helps that the radio signal is casting down to the Mini instead of up.

oops, can you explain more?  do not understand it, lack of kwowledge...  ;-)

This video not with original raw transmitter... On the RC antenna output is connected 3W HF amplifier and on its output is connected 19dbi panel directional antenna...
Violates EASA and ETSI laws in the EU ...

Yep, seems like it in the description. I wonder how drone sends feedback to 10km range. I understand that the remote controller is stronger with a 3db antenna but drone has still stock antennas right?

Yes, on drone is standard antennas. I thinking that his 19dbi antenna is used for receiving data from drone too. Panel antenna is strongly directional, from this reason is his flight low above the terrain (30m) .

Wow!! That's some distance.

Hi, I just ordered my first drone, a Mini today.  I do have a question about the video.  I saw that a high wind warning came up on the controller a few times.  My question is: did the speed of the drone contribute to those warnings?  I ask because I have been reading a lot about flying in a wind and the problems that can cause.

Awesome, thank you for sharing.

Exactly.  An antenna has the same gain both receiving and transmitting.

I think adding an external gain antenna is a good trick.  However, they are violating the laws by doing this because the way most of these statures are written, it is the ERP (effective radiated power) that is limited.  So even if they had NOT used the power amplifier on the RC transmitter, they would have still been violating the ERP regulations by using the high gain antenna to direct the energy in a specific direction.

Now, who did they hurt by doing this test?  Probably nobody because of where they were trying it.  But in an area where there are other users of this frequency band, they may well have caused harmful interference, and that's part of why the regulations are written as they are.

It's fun to see this, and interesting, but not legal, and not legal for some good reasons.

The wind warning seems to be pretty common on this drone,  there are numerous discussions about it here.

Yes it is

Today I was in CE mode at 40mt height and after only 400mt I lost signal (open area.. very few building)..  sorry but it seems very strange to obtain such 10Km result..

You have to keep in mind he wasn't using standard equipment. He was using a 19dbi panels 3W amps in CE mode. Which in effect is an antenna booster and from what others have discussed here isn't legal either.

pretty good?? that's amazing distance for ce wifi drone (without some hacking?), even if it's done in perfect conditions. imo.

edit: ah, boosted signal.

ah ok.. so not standard product... which is completely another story..

I believe that video is just a fake even with the booster antenna. The part that convinced me is the drone battery dying as he gets it back to him, reminds me of most action movies the hero disables the bomb after sweating and struggling for 30 minutes with 2 seconds to spare.

It does raise an eye brow doesn't it?

DAFlys:  with the weight (or lack there of) of this drone I can see how the wind can cause issues with it.  I will have to be VERY CAREFUL when I actually start flying.

Gusts seem to cause more problems than a constant wind speed.

Ive seen the same battery pattern with other long range tests.

I find it hard to believe this is stock DJI.

As far I know he uses 2 externally mounted batteries in addition to the original. This is a heavily modded system with basically the chassis and motors left untouched.

I think there is a 3rd party antenna installed.

That's impressive indeed!

One of many mysteries of this hobby is why so many people are getting a boner trying to fly as far as possible ... What is the purpose or reasoning behind this urge? On the other hand, I will never understand the thrill of hotdog eating contests either ...

The purpose of a boner is to release ..............errrr, just google it

I have no knowledge of how the DJI "WiFi" system works on these drones.  And I don't know if the video is faked or not.

But what I do know is that hams (amateur radio enthusiasts) have frequently modified standard WiFi routers to achieve extremely long-range WiFi connections to reach, for example, hamfests or other special events that were located far from any cell phone or other coverage.  This is done by using external amplifiers to boost both the transmitted and received signals AND using special antennas such as the famous Pringles Can antenna.

But one of the things that has to be done to allow long-range use of WiFi for normal internet access is to modify the firmware (or at least change some parameters) of the WiFi router to make it wait longer for responses from the connected devices (actually, in both directions) to compensate for the longer "time of flight" of the actual radio waves.  Yes, you must compensate for the length of time it takes for the RF signals to fly back and forth, even though they're moving at approximately the speed of light!

Once you get beyond a certain distance, when extending the range of a (normal) WiFi connection, the time of flight of the radio signals can be an issue.

Again, I don't know if the video is real, and if so, I don't know anything about how DJI's "WiFi" system works.  I'm sure it's not normal WiFi, though.  So I have no idea if you'd need to modify the firmware in the drone and the RC to achieve long range operation the way you do when you're extending the range of a normal WiFi internet hookup.

But just be advised that the hams do this frequently.  So it's not by any means impossible.

Just do a web search for "Pringles Can Antenna" or "Cantenna" and see what pops up.

Skip this sensational video to 5:11 and you may notice an elaborate WiFi range extender employed here to achieve such spectacular, but otherwise impossible goal ...

Yes,  he has another video on how to modify the controller.

Its quite interesting to see what's inside the controller.  Theres a lot going on in there.
