MJX B20 Short Review

The MJX B20 EIS drone comes with some advanced features such as a 4K camera that can record at 30fps and capture still images in 8MP. The drone also comes with a GPS system and an optical flow sensor for smoother flight performance and you can also fly the drone hands-free with its 3 intelligent flight modes. The MJX B20 has a flight time of around 22 minutes and a control range of around 600 meters. For less than $200, this is a very good drone.

Hi and welcome to my review of the MJX B20 drone.

Drones have grown exponentially over the past few years and the huge consumer demand has led to more drones at cheaper prices. However, not all cheap drones deliver on their promises but MJX are one of the few small drone companies that make very good budget-friendly drones.

The MJX B20 drone is one of the latest cheap GPS drones to hit the market and as you shall see from this review, despite costing less than $200, the drone comes with some advanced features including an actual 4K camera.

MJX B20 EIS Drone Review

So, this is a nice looking drone, it’s built from plastic, as you would expect from a low-cost drone, but it doesn’t feel cheap and has a solid structure. It is a medium-sized drone and has a pair of landing legs that expand its overall size. So, if you want a drone that is easy to carry and travel with, the MJX B20 may not be the best choice.

You can still travel with the MJX B20 if you want to, but you will need a suitable drone carry case.

The body of the drone has a kind of rectangular structure and has an all-grey colour scheme. The drone comes with powerful brushless motors which will allow the drone to hover better and fly more smoothly. Brushless motors also provide the drone with more speed and in the case of the MJX B20, it can reach a top speed of 40 km/h, which is pretty fast for a non-racing drone.

I do advise people to only fly at the top speed of any drone they purchase if they are an experienced pilot, otherwise, the likely hood of crashing into something and damaging the drone is inevitable.

Underneath each rotor there are colourful LED lights, most drones come with these kind lights now and they do serve a couple of purposes. The lights flash in a certain way when the drone compass has been fully calibrated, and they also help you to troubleshoot any problems that may arise.

There are also a couple of LED lights on the belly of the drone that can be used as a searchlight and along with the other LED lights, you can fly this drone in twilight hours. Although, you should only fly a drone at night if you are an experienced pilot.

There is a slot for a micro SD card on the bottom of the drone that can take a maximum capacity of 128gb and only takes cards that are class 10 or higher. To get the best video resolution, you will need a card that records at high speeds, so hence its best to get something higher than a class 10 memory card.

The drone is powered by a 7.6v 3400 lithium polymer intelligent battery that provides a flight time of around 22 minutes in perfect conditions. However, expect something more in the range of 18-20 minutes, which is still good for a drone that costs less than $200.

You get the option to purchase the drone with additional batteries which I always suggest people do because it will allow you to extend the flight time without having to wait for the battery to fully recharge, which takes a few hours.

The remote controller looks similar to that of the DJI Mavic controller, it has a minimalistic design and is powered by 2 1.5v AA batteries. Unfortunately, the batteries are not included, so you will need to purchase a few separately.

There is a nice OLED screen on the remote controller that will display vital data about the drone, like its GPS status, height and distance and battery level. There is also a separate smartphone holder that you can attach on the back and can hold a large smartphone but not a tablet.

The range of the drone is around 600 meters but if you use the FPV feature, which you will, the range is around 450 meters.

To use the FPV and intelligent flight modes, you will need to download the M RC Pro app which is available on both the Google Play Store and Apple App Store. One thing I have mentioned in my other reviews is how unreliable some of the apps from smaller drone companies are, however, the M RC Pro is one of the exceptions.

This is a very good app that is easy to use, although it could do with more frequent updates as there are some complaints that it crashes often.

Something you have to bear in mind is that the camera uses 5g technology to transmit live video feed, so you will need a smartphone that is compatible with 5g technology.

MJX B20 Camera

mjx b20 review

First thing I have to tell you is that despite this drone coming with an actual camera that can record in 4K, it is not suitable for professional aerial drone photography.

If you are looking for a cheap drone that can record and capture professional-grade videos and photos, I suggest you check out my article that lists the best drones under$500.

This drone costs less than $200 (and is only available on Banggood at the moment) and it probably has the best camera at this price range.

The camera can be remote adjusted that will allow you to get better viewing angles and it is stabilised by a 1-axis gimbal and is also supported by rubber shock absorbers. The camera has an electronic image stabilisation feature, this along with the gimbal and shock absorbers will eliminate a lot of shakiness and jello effect from your videos and photos.

However, you will still notice some distortion and hence the reason it’s not suitable for professional use, however, for a drone that costs less than $200, I think the overall quality is very good.

You can also stream live video footage in 720p quality and the video transmission range is around 450 meters, however, for the best quality, I suggest you keep well within this range and only fly when there is little wind.

This a good camera drone, especially for its price, however, if you would like more options at the $200 price range, click on the button below.

MJX B20 – Other Features

I have already mentioned some of the advanced features this drone comes with like GPS, optical flow sensor and the 4K camera.

The drone also comes with several intelligent flight modes, these will allow you to fly the drone hands-free and take better videos and photos.

Waypoint – Draw a flight path on the app and the drone will automatically fly along that route and come back home.

Orbit mode – Lock the drone on to a point of interest and it will orbit that position automatically.

Follow me – The drone will lock on to your smartphone and follow you from behind.

Automatic return home – This mode can be activated manually via the remote controller or the app and it is activated automatically if you lose connection or if the drone gets low on battery.

Something you must be aware of is that the flight modes I have just mentioned only work when the GPS signal is strong, so make sure you are connected to a lot of satellites before flying the drone in any of the autonomous flight modes.

Flight Performance

As you would expect from an MJX drone, the B20 has a very good flight performance, it hovers well thanks to its GPS system and optical flow sensor and even holds up well in slightly windy conditions. The transmission range is pretty close to what is stated officially in the instruction manual and the live video quality is also surprisingly good. Flight time is also pretty close to around 20 minutes and the intelligent flight modes work when operated in an area with a strong GPS signal.

Final Thoughts

I am impressed with this drone, it comes with some good features and an actual 4K camera. This is perfect for people who are looking for a fun drone to fly with but also a drone that can take some decent videos and photos. To find out more, click on the button below to check its current price.
