MARSMO B4W Drone Review


If I may, allow me to say that you will not be disappointed with the MARSMO B4W FPV Drone. This advanced toy has stunning features that make you want to fly it forever. Besides, this drone is quite good looking and stylish, the kind that you would like to show off at every opportunity.

Even starting with the obvious things like the foldability, the LED lights for night flights, the camera and so on, well, there is quite a ton to write home about for this drone. And it is all good!

Ok, seriously before we start to sound like a passage from the Song of Solomon book, let’s stop waxing lyrical and find out how this drone performs Is it worth the money that you will pay for it (just a couple of hundreds of dollars)?

Is the camera truly 2K? In the past, we have looked at drones with 2K camera resolution such as the Eachine EX3 quadcopter, and they are quite good. Let us just say that this drone meets and exceeds your expectations in everything including the price, the features, flight performance, camera and many more.


MARSMO B4W Features & Technical Details

You will not be disappointed. You can look forward to long flight range, high-speed flight, trajectory flight, long flight time and many more.

Design, build quality and durability

First, this is a foldable drone. We all know the benefits that this comes with. By folding it into a small and compact size, you can travel easily with it. Believe me, you will want to travel with it so that you can take photos and videos of your adventure.

Do you love big drones? If yes, you are in luck here because for an affordable price, you will get a drone that is sturdy, impressive and big.

The MARSMO B4W measures 17.7 by 17.7 by 2.9 inches when it is unfolded. As you can see, it is neither too big nor too small, but it is what we can call an impressive size. When folded, it measures less than half of its unfolded size – 7.5 by 5.1 by 2.9 inches. This manageable size can fit in your travel case without taking too much space.

The weight of this drone is 640g. That is well over the registration weight threshold of 250 g required by the FAA. Thus, the first thing to do when the drone comes is to register it with the FAA. Don’t worry, it takes just a few minutes and the registration fee is very affordable.

We cannot close the section about the build quality without mentioning that the MARSMO B4W comes with brushless motors which, as we know have various benefits. One of them is that they can fly longer without overheating. If you check the reviews for drones with the longest flight time, you will find that most of them come with brushless motors. Brushless motors are also quieter. They last a long time requiring minimal to no care and maintenance.

The exterior casing of this drone is made with high quality ABS plastic. This kind of plastic will not split open and spill the guts of the drone when it crashes with an obstacle in its flight path. When we said this is a high quality drone, we meant that in every aspect of the word quality.

Camera quality and video resolution

Since we all agree that the camera is the main reason why we buy drones, then it only makes sense to buy one with a high quality camera. And the MARSMO B4W does not disappoint at all, with its 2K resolution camera. If you have used camera drone with a resolution of 1080P, you know it is good. You can imagine just how better the much higher 2K resolution is.

With a wide field of view (FoV) of 110 degrees and being adjustable by 90 degrees from the remote controller, you can pretty much have all the flexibility that you need from your camera. But that is not all because after capturing your footage, you can edit it right from your smartphone using the built-in editor (in the app). You can then share the footage with friends and family on social media.

Enjoy a good first person view experience after downloading the app. You can only get a nice and smooth FPV experience by flying the drone in an area that is clear of trees and buildings since Wi-Fi cannot penetrate buildings.

Battery and flight time

What is the need for all the advanced features if you do not have the power to enjoy them? The B4W comes with a high capacity 3400mAh battery. You can get all of 22 minutes from this battery. This modular battery is easy to insert and remove. If you buy a second and even a third battery, you can make your flight time much longer.

The charging time of this battery is 4.5 hours. That may seem long but remember, this is a high capacity battery. At the same time, you can charge two batteries at the same time. The charger has two slots.

Remote controller

You get a nice looking and stylish remote controller that has a smartphone holder. This holder looks simplistic in design, and that is what we all want. It has a small LCD screen that shows you a few important things about the drone such as the battery status.

This remote controller connects to your drone through the 2.4GHz frequency. As we know, this is not like the 5GHz WiFi. Obstacles such as hills, building and trees cannot block this signal. It is little wonder then that the remote controller distance is 1600 meters, quite long!

You will need to buy 2 AA batteries to power this remote.

Flight features and functions

It would be pointless to have a drone with a high quality battery, remote controller and camera and then lack the most important flight features and functions. However, the goodness of MARSMO B4W drone is holistic, meaning it is good looking, durable and it comes with many flight features and functions.

Let us look at some of them here:

Altitude Hold

Lock the drone to a certain height and just worry about the horizontal flight. The altitude hold is very stable, safe and it enables the drone to take good video and photo footage.

Point of interest

Just take one object or person as the center of interest. Engage this mode and lock the drone to that person or object. It will go around keeping a good distance and taking photos and videos from different angles.

Follow me mode

Engage the follow me mode when you just want the drone to follow you wherever you go. This feature is useful when you are engaging in an adventure that you want to record. If you love sailing, kayaking, hiking, mountain biking and so on, take this drone with you and engage follow me mode to get your footage when you are in action. This drone can do a maximum speed of 40km/h. Match its speed with your car when taking road trips.

Trajectory flight

Open the map on the app, make dots on the areas that you would like the drone to pass by. Connect the dots with a line and when you launch the drone, it will follow the trajectory flight path. Just be sure to choose the route with the most scenery.

ARH – auto return home

This is a good safety feature to have in any drone. If wind velocity starts to pick up, it could blow the drone away. Just press the auto return home and the drone will come back immediately. Home is the place from where you launched.

One key takeoff and landing

This function does just what it says – either it launches the drone or brings it home to land. When you press the key, the drone launches but hovers at a given height to await your next move. It is one of the most important features in drones.

Who Should Buy The MARSMO B4W?

This high quality drone will cost you a couple of hundred dollars. It has an abundance of features, so you can buy it with confidence. Besides, it is sold with a limited warranty of 12 months.

Conclusion and Recommendation

You will never regret buying the MARSMO B4W FPV drone. It is incredibly good in every way that you can imagine. However, before you get to fly the drone, I have a few recommendations for you. One; read the user manual keenly. This is something that we reiterate in all of our drone articles. Two; fly it in areas that are devoid of obstacles. If this is your first drone, do not do the maximum distance of 1.6km. Take it easy. Three; find out whether you can get a spare battery so that you can double or even triple your flight time.
