Have you done any distance test on the XS812? Seems like there is a 200m geo fencing and I'm still trying to figure out how to disable the geo fence limit.
15:09 what does "prop pull" mean? Does it mean the camera leveling off to the original angle? If so that seems a desirable feature - to compensate for the tilting of the drone body...
@@RCEscape I don't know what was said; I didn't make the video... I thought I hear "prop pull"... And matching it to the video, I only see cam angle shifting...
Great test amd review. I like how visuo have developed this quadcopter, for me it ticks a few boxes, gps, flight time, value for money and design but if they had improved the range and maybe added brushless motors that would have given the bugs range some pretty stiff competition. 👍🙂
Aliexpress now has 2020 Version VISUO XS812 with a totally different remote control (looks like the Zen Mini or Eachine EG16). What is that about? I think they could have added an optical flow sensor for indoors, maybe.
How does it to Lyzrc l900 I was only able to fly my viseo once Good flight but than just drop from the sky Change motors but could not get it to lift up. Thanks
It could have been a superb upgrade, but the flight time was disappointing at around 12mins without all the high speed flying and 360 flips compared to the battle sharks version which could do about 15 to 18 mins with high speed flying and flips. Could the upgraded features like GPS and 5G wifi affected the battery consumption? By the way, does this quad have 360 flips and rolls? Also the flight range is just the same with the older versions, at around 100m, the 200m capability of wifi ohone app does not improve the range since the wifi capability depends on the transmitter range since i think this has no virtual sticks on the gps app. But aside from the follow me, waypoints, precise one key return home, fail safe rth and orbit features, I also noticed that visuo improved the design in placing a ventilated cover below each propellers. This would really help minimize the frequent damage of the moving parts but a direct motor to propeller connection would really be an upgrade.avoiding all the moving parts like gears, shafting and bearings.
Do you know if they have a sg700 4K GPS drone. Or what batteries will fit into 4K GPS from a 700 thank you yeah I like your videos to my friend does also he thinks you're cool same here
Hey pete ..I call and reliable..year old started to land when bat is less than 40 percent starts to land? When 30' high..starts to land..cant stop.? if higher acts nomal..?? Now little scared to fly. If over trees..water..could suck. Lo any ideas? Or are bats getting old?
When these Mavic clones first arrived on the scene more than a year, they were missing the most important feature, the GPS. So finally they decided to add the GPS. And they still kept the price way under $100. And how them adding a camera option, I talked you before that the advanced toy grade drones should off a higher end camera version. Another great review Pete, you really put this thing through paces.
Thanks Ron :) I think they are sending me the 5mp version too but I'll have to get it to be sure it is not another 2mp!!! lol I could be better with better range and with low voltage return to home but they had to leave some room for improvement for the next upgrade!!! lol
Awesome review. Maybe you should also review the Visuo xs812 LED Lamp Night Light Headlamp drone Accessory one day. And if it fits the xs809s & xs816 too.. it is super cool to have.
You flew the drone for 2 minutes and 50 seconds before you started recording video so add that to the 12 minutes and 30 seconds for a total of 15 minutes and 20 seconds and the second you took off the battery dropped down from 100% to 82%. Not sure if the sudden drop like that is normal or not.
Do the camera and video buttons work on the remote? I just got the battle sharks one and the buttons on the remote for video and pics does not work. The buttons are also blank i.e. no icon indicating function. It almost looks like they were forced remove them for a patent issue or something. When you click the blank pic button it blinks the LEDs like it's supposed to and the the blank video button blinks the back leds but nothing goes to the SD card. However if you use the buttons on the app it does get stored to the sdcard.
My controller does not turn on with new batteries. Can it be repaired or where can I get a new controller, the drone is pristine, only flown one time. past warranty. Thanks!
Hi...with models being upgraded now to 5G wifi, will it still possible to fly this drone without connecting to its wifi? The App which can be downloaded, do you think can help fly this drone alone?..other functions may not work without wifi, what I like is the new gps and video, but 5g wifi not available to my mobile..thanks
Nice video review Pete , quite in depth, however I feel the LVC stopped you testing the very few features left to try. Kudos to you mate, all the best from across the pond : Thumbs upward !
Hi, nice review and cant wait for the continuation review on the waypoints and followme features, and hopefully the usage of 5Ghz repeater which is now in the market (I have seen a video using a dual 2.4/5ghz switch wifi repeater) and placing the hidden TX antenna straight up the top of the quad just like your previous videos on xs809s...I am sure the range would be amazing for the TX and Video feed....but another thing you have not pointed out is the range of the Tx which is very disappointing with just about 100M, been expectung a 200M range...good job!
Oh , that's great ! Could you make a little bit of full screen of the sd recorded video when you do the review, please , if it's not an inconvenience of course? Thanks in either cases , and thanks for the work you do :)
Love your channel mate, your one of my go to channels for sure.. But the transmitter gimbal sticks definitely don’t feel like hobby grade transmitter gimbals, they are far to light and springy and hollow feeling, they are one of the worst things about this drone, other then that though it’s a good toy grade gps drone I like mine.. happy flying..
Thanks for the review. This one seems like it needs some work, still a little buggy. What's up with that battery meter, it's all over the place. And after it landed it shot up to 60%. Maybe you have a bad battery or the C rating is to low for that quad.
Hey there, great review of the visuo. I just received mine and also does the "plateau effect" that you mention after going foward. Is there a fix for this? Other reviews don't seem to have this problem.
?They don't? Because, now I am thinking it is a part of the GPS altitude hold effect that was causing this so the quadcopter does not nose dive into the ground and it is actually a good thing.
RC Escape Mmm ya as far as I know on other few videos on the xs812 it doesn't veer left after stopping on forward motion. Actually does the opposite going backwards, veers to the left. Oh well just got it today so hopefully can rectify this... Thanks again for the reply!
I do not have any issues with it veering to the left. I'm referring to the plateau effect being the nose rises up after forward pitching for a second and not to the left. Are we talking about the same issue when referring to the "plateau effect"?
RC Escape Whoops sorry I guess not called the plateau effect. I mean in your video around 15:15. After going forward it pitches to the left. I haven't seen anyone else with this problem or experience on other 812 vids. On my 809hw doesn't have this trait. Well hopefully it corrects itself after I fly it more. Thanks again for your inputs. Keep flyin!
Can you tell me what phone smartphone other words in Android would do 5G Wi-Fi and second isn't the gearing in this the same as the battle shark and the one before it. Thank you great videos.
Aubrey Mccoy Ive no idea what phone is compatible on android but you can check by simply looking at the specs on any given phone on google search and it will show the WiFi specs. And yes the quadcopter is identical to the previous models except the design, 5g WiFi and the gps :)
Got a problem with this drone. The app sees 75% battery on Start up. but when u move the drone it reads the battery as 20% and starts the low battery warning on The transmitter. So annoying I need the app for the GPS. Any help?
Hi everybody _ı bought xs812 2 years ago.It worked perfectly but yesterday I tried to fly but the escanding power was not enough to fly. I changed batteries, still same. Any suggestion about it. Thanks in advance for your support
Please Help! I did buy the xs812 drone. Aftern binding the control with the drone I press the bottom right button to calibrate the compass. At this time both green and red lights are blinking. I rotate 3,4,5 times the drone horizontally and the red lights become solid. I then turn it nose down and turn it 3,4,5 times. The green lights become solid BUT the red lights start blinking again! Why this? There is NO WAY at all to get to the point where all green and red lights are solid! Can anyone help me understand? Thanks a lot!
Hi, love your videos mate! You helped me decide to buy two drones before, much love! I have a question, so I am torn on getting either this drone or the XS809S, I see people are saying that XS809S has really limited altitude, is that true? In one YTbers video his height was really low and limited, but on your modded XS809S you went much higher, did antenna mod affect the max alt? Also is XS812 worth getting in comparison to the other, it costs almost double but has shorter battery time vs the shark, does XS812's GPS improve the flying experience or does it feel better to handle in general? I really do want this model, just trying to justify it's cost if it's worth getting this over the other drone. Thanks again for your videos! :)
You can fly easely at high altitude with xs809s. When the battery is at 25% power left, the drone's lights start to blink, the altitude limit kicks in, and then you are limitded with cca 30 feet of height, also you can't do flips. This is not written in any manual, I tested this functions myself. With recharged battery all the functions works fine. I own xs809s fot about 2 month, it's a good drone, flight time is awesome. Now I'm just waiting for a good review of xs812 5Mpx camera, and compatibility with android.
yes, turn on the quad. go into the wifi settings on your phone. if you don't see the drones wifi network available, your phone is not compatible with 5g wifi. if you see it then tap and connect. go to the app and start the interface.
my transmitter for the sx812 beeps four times and flashes the red light fast and the drone lands itself automatically i cant see anything about this on the manual can someone help me??
BE WARNED!!! Do not fly these more than 2 battery changes in a row without letting them cool down. The very weak plastic motor supports distort and cause all kinds of problems. Found out the hard way after this happening twice to me. easy enough to change out the arm housings, but its easier still to just let them cool off a bit. Other than that they are a fun, fast, and cheap little GPS quad.
SHAMEFUL how the companies usually Do Not list the motors - which are NOT BRUSHLESS in their specs. Otherwise, somewhat decent quadcopters appear to be 'dialed-in' as competative with the better designed of the bunch that run BRUSHLESS. Also camera angle cannot be remotely adjusted. 👎 Junk- IMO. Wulfy
Thanks for this video . It's the only one i found which has so much more details on how it works.
It would be nice to see brushless motors in the future.
Best review I’ve found on this so far, very many thanks!!!
Have you done any distance test on the XS812? Seems like there is a 200m geo fencing and I'm still trying to figure out how to disable the geo fence limit.
if they throw brushless motors on this I am sold.
Good review Pete, I have the original version with altitude hold and it still flies pretty well.
I think what they need now is to put brushless motors on it!!! :)

Clearout Games xs812
FPV feed looks pretty good for wifi.
between visuo xs812, xs809s and xs816 which is better and you recomend?
How do you set the Return to Home altitude? I only see settings for Waypoint altitude on my app.
Aliexpress now has 2020 Version VISUO XS812 with a totally different remote control (looks like the Zen Mini or Eachine EG16). What is that about? I think they could have added an optical flow sensor for indoors, maybe.
Don't know. Maybe they upgraded / down graded it.

and the 809s has brushless motors isnt it?
can you disable the gps to make it fly longer?
