First DJI NEO Flight with DJI RC2 and XREAL Air 2 Pro AR Glasses
The DJI RC2 controller has a USB-C port (output) that supports video out and most AR glasses use USB-C as their video in. As a result, the use of my XREAL Air 2 Pro AR glasses to fly my DJI NEO is as easy as plug-and-play by just connecting the DJI RC2 to the AR glasses with the supplied USB-C cable, and the image on the screen of the DJI RC2 is mirrored to the glasses.
This is my first longer distance flight with my DJI RC2 and the glasses. By the way, I used the same setup and flew my DJI Mini 4 Pro. My experience has been good and I am satisfied.
In this flight, I tried to start with slow and low flying just like a FPV drone. It proved to be a little challenging as the drone may react to the control sticks operations in a rather different way. Anyway, it was good.
Then, I flew the NEO to around 380m at 39m high to gain some experience of flying this drone. I found the following:
(1) The speed in the NORMAL mode is way too slow compared with other DJI camera drones such as Mini 4K.
(2) Even in the NORMAL mode, the drone could over- or under- react to stick operations. If the drone is flying high, one would not get this feeling; but, in low flying it is very obvious. I am not sure it is a drone's flight controller issue, RC2's issue or a combination of both. I guess I need to get more experience to fly low avoiding obstacles.
(3) The camera has only 1-axis Gimbal. As a result, if you fly the drone sideway, horizontal is tilted. This is a major drawback compared with other camera drones.
(4) I found image sharpening is too high, which agrees with other people's finding. I plan to lower the image sharpening setting and do a video on image comparisons in the future.
This is what I learned via this first flight. In summary, I like the XREAL Air 2 Pro AR glasses. It gave me no trouble in flying the NEO and other drones that can be flown with DJI RC2, DJI RC Pro and DJI Smart Controller. I will do another video showing how to use AR glasses to fly other drones.

javascript 的非同步算是一種交錯執行嗎？ 如果需要等待的任務，例如 call api，就先擱著等到有結果再呼叫 callback，call api 之後的程式就不會被卡住。
Very good 👍seven crash ? Or nothing 😉
No crash at all. My little NEO passed all the tests. The only exception was it cut corners once; but, it could be my fault. For the fourth one, maybe I could go a little farther and walk toward between the trees. I will definitely try it some days later. Because I live in an area full of trees and forest, when I travel I would need a drone that can do these things that many would even consider.
THANK YOU! Many "experts" have said what you just DID can't be done - Ha. Much appreciated!
Thank you very much. I am not an "expert" but I'd like to try everything I can put my hands on it. :-)

what do you think about durability of potensic atom
IMO, the drone's durability is rather good. I bought an ATOM right after it was released and it is still good even though it crashed a couple of times. However, I strongly suggest that get a good hard case to store the items because the supplied case is too small and could cause damages to the props. The power supply is an issue because the plugs cannot be folded and they could "punch" to something. In fact, none of the supplied cases, DJI included, is well-designed. They are either too small, too tight, or too crowded.
I certainly agree with CK Shene here. The drone seems actually very durable, and a rigid case goes a long way to keep it in great shape. I love the Pelican-style* cases, which are super easy to keep handy in your vehicle (I do real estate photos). *I highly recommend my economical orange "APACHE 2800 Weatherproof Protective Case" frequently on sale at HF. Really well made and carries the whole kit with ease.
Nice content just wondering why your views are low
Hello, thank you for your comment. I am not a professor UA-camr for profit. Hence, I don't need the no. of visitor to boost my profit. A low key approach is perhaps my favorite. Recently, I made videos on Concurrent Computing, a crucial topic in Computer Science for students. This series lectures is what I really want to do in my life time. 🙂
@@ckshene7212 Thanks for your response
I do not see POI here. it seems more forward. am I wrong? In POI I have to see circling.
No, I did not use POI because my goal was just determining how far it can reach in this woody and hilly area. Hence, I did not test for circling. :-)
and also flying @118m high and 760+m distance is stupid.... if u are flying that far... u should increase the altitude at least 200m... so that the RC signal wont break
Stupid? You perhaps are very wrong. I can fly other camera drones at no more than 120m height to reach 1.5km in the same area. Keep in mind that the document indicates a distance much longer than 760+m. I fly many mini drones in this area along the same route and this is the only mini drone that failed at this distance and height. So, who is stupid?
did u put a sticker on top of the drone? if u did... thats the cause
I have the mini 2, took it for a flight on Monday just gone, it was 40 m high, I only flew about 200 m away, the interface went black, remote lost signal to drone and it fell out of the sky. Now the flights I wanted to do, over our local park and woods etc I have lost trust in it. I’m very new to the drone “fraternity” and this is my first 4K gimbal GPS drone.
can it exceed over 500m and fly waypoint flight
No. If the drone is over 500m from the current position, the app won't let you place a waypoint. So, plan the WP first (on a map) , go to the center of your route, fly the drone up and finally setup the waypoints. This would minimize this 500m restriction.

thx for guide bro! it helped
how is the antenna placed in the Atom? is it horizontal ? or is it vertical in the foot of the arms??...if it is horizontal you lose 20db of signal....from vertical controler to horizontal drone....cross polerization no good
Thanks. I am aware of the issue. In fact, it does not matter because it is perhaps due to the very weak VTS signal strength. Of most of my sub-250g and sub-$300 mini drones, only DJI Mini 4K can go very far to about 3km along the same route, while the others are inferior. The Potensic ATOM is perhaps the worst. BTW, the ATOM's antenna is hidden somewhere (perhaps in the front legs) in the drone body and cannot be adjusted. This means that the distance which is due to the VTX strength is an inherited weakness. Potensic should fix this problem in their next release.

I initially was having this issue. Though many say it's a semi professional drone and does not need to be compass calibrated, it seems still needs to be done.
But, compass calibration is not related to losing GPS signals. I agree completely that other than the DJI Mini drones all other mini drones should do a compass and a gyro calibration before taking it to the air. The drifting and/or flyaway shown in the video is losing GPS signals and stick movements had no effect. I would believe that this Faith Mini has a quality control issue.
What is the controller does not blink in red at all? In is red for a few seconds and then immediatly changes to blue. Also the bi ding only lasts for 2 seconds and does not seem to work… HELP
good bye
I intended to send the following to Potensic, but got blocked.. "Well. it has been 3 months and I've got no help from ipotensic to repair a damaged Atom drone. Potensic insist that I use some version of paypal. I have tried and you insist that you aren’t getting it. I asked you for the paypal address so that I could send to you the through paypal. It did not work. I got a friend with a computer to try to get through to you on their computer. They could not get through to you. Same problems that I encountered. Three month of stonewalling. It is time to say good bye to you and hello to potential Potensic customers with a potential need for your help in repair. Three months! You have to admit that I was patient. I leave you as a more cautious buyer and the owner of a broken drone as a reminder to me to be cautious when dealing with someone you do not know. " Buy with caution .
I too saw your point 4:22, though I was hoping that you or someone actually were able to store a Waypoint flight (settings) and then be able to show us how to recall those Waypoint settings....maybe a list shows up or something. But I've tried on my new Atom and it will fly the Waypoints, Very Cool, but when I hit the store button (as you show) nothing is displayed. Then when you hit the list button (next to the store button) nothing is displayed...pretty much like nothing is storing or able to recall a list of stored Waypoint flights.

this is engineer from cfly,there is few issues which you didn't mention: 1.when it hinted the wind is too big,you should start RTH immediately,it's a small drone,wind is the factor which we need to consider. 2.why the GPS is losing?cause the wind blew the drone all the time,the GPS work abnormal 3.when GPS is losing,RTH is not working,cause drone don't know where to return,in this case,you need to take it back manually.
Thank you for your reply. This is my reply to your reply: (1) Let me just limit my answer to the sub-250g and sub-300USD mini drones. I currently have DJI Mini 4K, Potensic ATOM, FIMI X8 Mini 3, HolyStone HS900 and your Mini 2. I got this high wind warning all the time in spring because my location is windy in spring. Except for your Mini 2 none of the others has this problem. I flew the FIMI X8 Mini 3 moments before and the wind speed was 10-15m/h. This is not a very strong wind and all of my other mini drones survived but yours. (2) GPS failure due to being blown off? If you look at the screen recording, the drone flew along the path smoothly. There is no theory suggesting that GPS could work abnormally when wind is blowing. If I fly my drone in sport or fast mode, given your theory my drone would not get GPS correctly. Additionally, my fast FPV drones would also fail. By the way, none of my other mini drones had this issue. Either the GPS sensor malfunctioned or your GPS system software had problem. Moreover, my vehicle moves much faster and dash cam can still pick up the GPS signal properly. (3) Then, why is the screen showing RTH still working and cannot be cancelled? I fly FPV drones without GPS all the time and I am able to get my non-GPS FPV drone back from that distance easily. The problem is that your Mini 2 became uncontrollable (i.e., no response to stick input). This suggested that your TX + FC system is also problematic. In summary, your answers to my issues are not something that can convince me. Thank you anyway.

The wind doesn’t have anything to do with the aircraft losing GPS satellites so quickly like it did, the true issue is that the GPS module and gyroscope board are of a very bad quality and this drone as well as the original Faith Mini 1 had the exact same problems with loosing GPS also, toilet bowl effect while hovering, motor issues, camera gimbal issues, app issues, firmware issues, NO REAL CUSTOMER SERVICE SUPPORT,… The list just goes on and on. Just be honest to your customers and do right by them by helping them with troubleshooting the issues and fixing the problem on the manufacturing side, then people will trust your brand and it will have a chance at prospering. If not, no one will buy your brand because it will be known as cheap unreliable junk that’s not worth buying no matter how cheap it costs. All other brands like Hubsan, Fimi, Potensic, Autel, HolyStone, Ruko, etc., have better CS service and they try to fix the problems as fast as they can in order to resolve issues but CFly unfortunately does not do this and therefore it fails.
What a pity 😵💫
Lovely views 👌

Bom dia meu amigo 👋, Like registrado 👍
Potensic Atom SE drone owner, update for the camera, zoom option.
Sorry. I can't say anything about that because I am not with Potensic. On the other hand, I would rank my needs in this order: (a) make the video transmission/penetration better and stronger; (b) make a better Gimbal so that it won't tilted to one side when flying even after calibration; (c) redesign the app GUI so that its display avoids the left side being blocked by the iPhone's black strip (i.e., camera), change the exposure compensation to +/- 0.3EV rather than +/- 0.5EV for a better control of exposure, and allow for WayPoint pre-planning without the requirement of flying the drone first. (d) The QuickShots should provide virtual fence warning before the execution of any flight rather than stopping the flight and hovering when the drone violates the virtual fence. There are others I would like to see changes, but for now the above listed are the most wanted one. After finishing my study of the ATOM, I will send a list to Potensic. Whether they will take it seriously is out of my control.
Sometimes trees mess up the signal, I've lost connection to my Mavic Mini just through the thin branches at the top of trees 🌳 😊
Not a very good after sales service support team behind potensic. Believe me I know.
In my case, Potensic is better than most Chinese drone makers, except for DJI. At least Potensic tried to respond when most Chinese drone makers either ignore my request or respond with nonsense messages a couple of times and then never responding. I hope your problems were resolved to the degree that satisfies you. Otherwise, send them messages and boycott them! Please keep in mind that Chinese business models are not the same as those in the US. We have to let them know what we think and want. Or, we won't buy their products.
I could reach 3km with just my SE
As mentioned somewhere (or elsewhere), the flight distance is environment dependent. This is the reason I have been trying to fly my drones along the same route at approximately the same conditions.
Hi, have you been viewing every possible potensic Atom drone review video as possible with the intention of buying a potensic drone, and you have decided that the potensic drone is the one for you, so now your ready to depart with all your hard earned Cash, GREAT.????. Before you go and spend all your hard earned Cash, can I recommend that you carry out a complete and thorough research into the after sales service support team behind potensic where ever you live, doing this just might save you a load of cash in the future or even loose you a load of cash in the future depending on how well you do your homework, I own a potensic Atom SE, that as developed a fault in that the battery is not holding a charge, I contacted potensic explained everything to them and they seem to agree that the battery is at fault because they told me that I needed to buy a new battery from potensic with a small discount offered to me, yes I CAN BUY A NEW BATTERY. Surely a battery should last for a lot longer than six months, although it could have been worse it could be the drone that was faulty.

請問這裏可以釣魚嗎?
冼老師的課程說的真好，早期的編譯龍書翻譯的品質也非常好!
