9 Best Underwater drones in 2021 (and what to avoid)
The MJX Bugs 4w is a relatively new drone on the market and you're certainly looking to see if it's the best in its price category.
This review will follow every possible question you may have along with detailes about specs like:
And a lot more (including footage).
The MJX Bugs 4w is the first foldable drone from MJX and comes with a TON of great features and a 2k camera, all under $200!
The controller is way more compact and does look like the Mavic one, but that’s not a bad thing.
Brushless motors, flight modes and a camera that can swivel up and down from the remote, this quadcopter is what the MJX Bugs 5w should have been all along.
As a side-note, I reviewed the Bugs B20 from MJX and it has Electronically Stabilized Image.
The camera is still not that great, as it doesn’t come with any stabilization.
What’s most unique about this quadcopter is the double battery charging system.
Not only can you charge 2 batteries at the same time, there’s also LED screens on the sides showing when the batteries are charging, that turn off if it’s not charging.
There are also accessories that you can buy with this drone already, like additional spare batteries and a bag.
The MJX BUgs 4w does return at the starting point by itself after it disconnects from the transmitter.
Not only that, you can also call it back by the press of a button (RTH).
It does automatically come back to the starting point after it reaches about 15 percent battery or so.
You can cancel this process, but it will limit you by geofencing to go further than 20m (sometimes it doesn't work).
The maximum height allowed to fly in the USA is 400feet which is just over 120m.
The Bugs 5w can go over 100m but no more than 150m, so you're right in that range.
The camera can be rotated 90 degrees from the transmitter and actually records in 2k 20fps.
The camera quality isn’t the greatest, even in 2k resolution it doesn’t look much better than what you can achieve with other similarly priced models from MJX.
It has vibration dampeners for removing the jello effect, but no actual camera stabilization involved, like a gimbal or EIS.
A slight disadvantage is that the camera records in 20fps, which is not as smooth as I would have liked it.
Short answer: any phone that supports 5g 802.11 ac wifi.
All the iphones have this frequency and usually newer android phones, but there are meny exceptions.
If you want to check your phone compatibility, go on GSM arena, search for your brand and then look in the specs if it has 802.11 ac wifi (the AC part is important).
And no, it's not Air Conditioner.
You need at least one of these, as you might find yourself not having enough time in the air.
This is a great way to carry this quad around, with a few spare batteries also.
If you don't want to wait up to 2 hours at a time for one battery to charge, why not do a few more in paralel.
The controller is a much welcomed change from the original bugs series transmitters that were pretty big in size.
This one is about the same size and look as a DJI Mavic one.
It shows distance, battery life, height, signal strength directly on the LCD screen on it. That’s really helpful in moments when you lose video signal and want to see if the drone comes back to you. The remote controller has a range of 1km, even though the FPV is at about 300m.
You can also
There are ultrasonic sensors underneath the drone, so it’s going to fly very stable when it’s closer to the ground.
It also has an added optical flow camera for additional flight stabilization.
The flight modes this drone comes are pretty standard:
The waypoints flight mode actualy works, unlike many chinese drones these days.
The point of interest flight mode is not extremely precise, but does work as intended.
The connection to the app should be simple.
The app for this drone is called JJRC X app and you can download it from both playstore and itunes.
The MJX Bugs 4w app also works (called mjx bugs GO).
You must make sure your phone can connect to the wifi of the drone. The smartphone needs to support 802.11ac wifi. Check this online by searching "your phone brand 802.11ac" and you'll find out.
Then search for the wifi and enter the app and you should see the image.
It's important to know that before every flight you need to do the "GPS calibration dance".
After you bind the transmitter to the quadcopter you need to do the following:
How do you unlock the motors?
By pressing the red button and keeping it pressed for a second
How to bind the drone to the transmitter?
If the drone hasn't been bound yet you can do this by pressing the red button and holding it.
Then press the on button at the same time.
How to change the camera angle?
You do that by the conveniently placed scroll wheel on the top right side.
How to turn the GPS on or off?
There's a button on the right side. The drone will fly faster in non GPS mode.
I don't really think you can get better for under $150.
All the specs, the flight stability, modular camera that even comes with the ability to stabilize video (to some extent) make it a great choice.
Having GPS for return to home and flight stability is also a great feature for beginners to have.
