Design and build 

As you saw in the first paragraph, this is a foldable drone. This has a lot of benefits like you can travel easily with it, it doesn’t take up much space, etc. . It’s always good to travel with a drone so that you get nice photos and videos from an aerial view.

The MARSMO B4W measures 17.7 x 17.7 x 2.9 inches in its unfolded state, when you fold it will measure 7.5 x 5.1 x 2.9 inches. As you can see, the drone has a perfect size, it’s not too big nor too small, but it is what we can call an impressive size. The drone weighs 640g, which can’t be called heavy, but you will still need an FAA registration for that in some countries. 

MARSMO B4W Quadcopter Package Review

As for the build quality we have to mention that the MARSMO B4W comes with brushless motors which, as we know, has a lot of benefits. One of them is the fact that they can fly longer without overheating. Brushless motors are also quieter and they need less maintenance, but still they are more reliable. The drone is coated with red and black colored high-quality ABS plastic, it’s a kind of plastic that will not split open and spill the guts of the drone when it crashes with an obstacle in its flight path. This plastic is not just durable but it’s also lighter in weight.  


The B4W has a high capacity 3400mAh battery which will get you 22 minutes of flight time. This is a modular battery that is easy to insert and remove. If you buy multiple batteries you can get much longer flight time. The charging time of one battery is 4.5 hours. That is not a short time, so always remember to charge them in time. The charger has two slots, so in case you get two batteries, you have the chance to charge them at the same time. 

Remote controller 

The remote controller is a nice looking and stylish device. The controller has a smartphone holder so you will get a good FPV experience with this drone. The holder looks simplistic and has a steady hold.

The controller has a small LCD screen that shows you all the important telemetry information. The controller works with a 2xAA cellular battery which you have to buy on your own. The drone connects to the remote controller with 2.4GHz frequency. This is not as strong as the 5GHz WiFi, but it’s still a steady connection. The signal can go through buildings and trees cannot block this signal. And you will need that because the drone has a 1600 meter flight range. It’s an incredible distance. Most of the drones at this price range have around 100-500 meters, and this is way beyond that. It’s true that a crowded environment can shorten this distance by around 100 meters but it still should be enough. The drone can also be controlled from the app, but it’s recommended to use the standard remote controller if you can.  


The camera is one of the main reasons that we buy a drone, it must make a clear and flawless image. The MARSMO B4W does not disappoint at all, with its 2K camera. If you ever used a 1080P camera, you know that it can provide you a great quality.  And a 2K camera is almost 2 times better than that.

It has a wide field of view of 110 degrees. The camera angle is adjustable by 90 degrees from the remote controller.

MARSMO B4W Quadcopter Features Review

The app provided by the manufacturer has a built-in editor, so after you capture the footage you can edit them without transferring them to your computer. This way you can share the best images and videos instantly on your social media platforms. This is especially handy if you don’t have much skill in video editing. As you saw in the controller paragraph you also get a first-person view experience after downloading the app. 

Flight features 

We saw that the drone has a nice build, a good flight time, and a  good camera, but all of that would be pointless without some flight features and functions. Luckily this drone has some of them. You can use them to create even more cinematic and entertaining videos. 

Here are the flight features the drone is capable of: altitude hold, point of interest, follow me mode, trajectory flight, auto return home. These are not just handy features, but they ensure even a safe flight. They could help you a lot if you’re a beginner in the drone business. 


You won’t regret buying the MARSMO B4W Quadcopter as you saw in our review. It is incredibly good in every aspect a drone can have. It’s true that it can’t do as much as a DJI Mavic Air, but that drone is in another price category. This drone is more for the people who don’t want to spend that much on a drone but still wish to try out the joy of flying a drone.  

Before you get to fly the drone, always read the user manual keenly and make sure to fly it in areas that are devoid of obstacles. And take it easy, first, learn all the basics, and that you can make even crazier stuff with the drone. Just pay attention to the drone and others.

If you want to order the MARSMO B4W you can check out the price on Amazon.

  1. I just bought this drone and it’s everything that you talked about and more but I’m kinda unsure where I can get another battery for it. I’m not talking about a universal one or one similar to it but the exact one that it comes with. If there’s replacement parts and accessories I can buy?
