This week, we are introducing another brand new foldable camera drone that is currently on sale. Meet the MARSMO B4W drone, this is one of the most advanced quadcopter that comes with a long flight time and relatively good remote control distance. If you are looking for the best drones under $300 such as Holy Stone HS720, Holy Stone HS700 or even Potensic D88. Then you have come to the right spot because in our in-depth review about MARSMO B4W drone, you will learn why this quadcopter is the best pick for you.

Through sifting the customer reviews and researching this drone gadget, we assembled a MARSMO B4W drone review. In this article, we will go through the basics like its design and build quality, flight performance, features, accessories and more. The purpose of this review is to help buyers like you make an informed decision. Whether you are looking to have your hands on one of these smart GPS drones or not, we will share why you should buy a MARSMO B4W drone.

What’s Inside The Box:

Before we dive in details, I want to talk about what to expect inside the box. Personally, I think this is the most important part of doing the drone reviews because you get to know what is included and whatanot. So that you can plan ahead and buy additional items if needed to. For instance, this drone have built-in camera and can deliver footage directly to your mobile device as well internal. But it doesn’t comes with a MicroSD card. So for this drone, we recommend purchasing a 64GB MicroSD card to go with it.


Inside the package, you should expect to get these following accessories:

  • MARSMO BW4 Drone
  • Remote Controller
  • A Set of Propellers
  • USB Charger
  • Modularized Battery
  • Battery Charger Balancer
  • A Screwdriver
  • Traveling Case
  • User Manual

Design and Build Quality

The build and design quality of MARSMO B4W drone is exceptionally crafted to last for a long time. This quadcopter uses combination of durable material from alloy metal to ABS plastic that provides strong damage resistance against impact. Furthermore, each motor arms are outfitted with brushless motor. Which reduces burnouts and improves propulsion force for a much longer flight time at reduced battery consumption. Not just only that, it helps deliver a higher maximum flying speed with quieter flight performance.

MARSMO B4W Drone Desgin

One of the design feature that we liked the most about this drone are its foldable motor arms. Which means you can easily fold this drone and take with you anywhere on a road trip or hiking. It also comes with foldable propellers that further minimizes the amount of space that it takes. MARSMO B4W is a drone that is crafted for beginners and recreational remote pilots as you can see how it is designed. Mainly with a power button located on the front for easy to activate.

Finally, this quadcopter comes with a built-in 2K HD camera on a 1-axis gimbal stabilizer. However, it is not that advanced compared to Holy Stone HS720 drone due to limitations. If you are simply looking for a camera drone that will teach you the basics of aerial photography before you plan to buy yourself a DJI Mavic 2 Pro / Mavic 2 Zoom. Then MARSMO B4W drone is  great candidate to go for first due to its built-in GPS module that provides you aerial perspective flexibility.

Flight Performance

In the next part of MARSMO B4W drone review, we are going to talk about its flight performance. Just like every other drones such as Eachine E511S and HASAKEE Q8, you need to know how well this drone performs specifically the ease of controls and aerial capabilities. First of all, the MARSMO B4W drone comes with a modularized flight battery that provides up to 22 minutes of flying time. Which alone is plenty of time to soar the drone around.

One of the major flight performance advantage that this drone brings to the table is its undisputed remote control distance. Indeed, it has a maximum flight distance up to 1,600 meters. Which is definitely way more than what Holy Stone’s premier drone has to offer. Although, as good as the MARSMO B4W drone is, it comes with some limitations like fewer features that doesn’t hinders its flight performance that much. But as a beginner who wants a drone, more features is always a good thing.

This drone comes with a flexible speed mode that makes it easy for beginners who has no prior flight experience learn how to fly. Once you master the basics, you can adjust the speed setting to challenge yourself and hone the piloting skill. In addition to that, the MARSMO B4W drone makes a smart use out of optical flowing position that provides stability and precise flight controls. Overall, the flight performance of this foldable camera drone is by far one of the best.

Advanced Positioning System

The MARSMO B4W drone is built for accurate and precise mainly to make it simple enough for beginners. As a matter of fact, there are four positioning system that work independently of each other to provide a lighting smooth flight experience: Ultrasonic Sensor, GPS Positioning, Optical Flow Positioning and Barometric Positioning. Which I will further talk about each integrated positioning system in details on the next paragraph. I have included an image to show you how each system works that benefits you as the beginner and recreational remote pilot.

MARSMO B4W Drone System

Ultrasonic Sensor: This is one of the most advanced positioning that encompasses built-in sensors which measures the landscape to provides precise positioning. Ultrasonic sensor utilizes frequency that bounces from the drone to terrain to avoid rough landings.

GPS Positioning: This is a common feature, yet very useful for communicating with the satellites to acquire precise positioning. A GPS-based drone keeps its position steady to ensure a smooth flight experience.

Optical Flow Positioning: This system uses sensor that allows the drone to hold its position without the need of a remote pilot. Essentially, this feature serves as back-up in case if the GPS module doesn’t work due to poor communication or lack of signal.

Barometric Positioning: Finally, this is another useful feature that encompasses the flow of air. By detecting changes in the level of air pressure, it automatically shift to balance the pressure out so to ensure a precise height level

Final Verdict: Should You Buy MARSMO B4W Drone?

Now that we have come to the conclusion of MARSMO B4W drone, you might be wondering if you should buy yourself this drone. Let’s recap on what we talked about throughout the review. First of all, we know this smart camera drone comes with an impressive flight time up to 22 minutes. Furthermore, it has a maximum remote control distance up to 1,600 meters which is more than what most of the best drones under $300 has to offer.
