REVIEW – The brand name that most people who are interested in drones think of starts with a D and comes with a wallet stinging price tag. Finding a drone that has an impressive set of features but a price tag of less than $200 can be a big challenge. Holy Stone was up to that challenge when they created their HS120D drone. Let’s take a look AND take it for a spin.
What is it?
The HS120D is a quad-copter/drone from Holy Stone that has a set of features that you would normally expect from higher-end drones. Features like a 1080p camera, GPS hold, follow me object tracking, and one button lift and land.

Design and features
The HS120D is made of lightweight black plastic with an X-shaped quadcopter design. Although this drone is small, the wings do not fold, and it does not come with a carrying case, so it’s not as convenient to transport as some pricier and fancier folding drones can be.
Each of the rotors has a status LED built into the tip which helps you see the status while calibrating the drone and while it’s in flight.
Below the center of the drone is the camera assembly. You’ll also notice the two landing gears that are attached to the bottom of the drone. Holy Stone was nice enough to include 2 extras in the box just in case you lose or break them during your flying adventures.
Also included are propeller guards which snap into the ends of the rotors to protect the propellers from tree limbs and other obstacles. Extras are great because you’ll go through them pretty quickly as you’ll find that they just disappear. But, once you get comfortable flying the HS120D, you shouldn’t really need them.
Unlike the drone itself, the remote controller does fold up for easy carry. The controller has two joysticks on top as well as buttons for power, GPS toggle, auto lift off and land, and a returned to a home button.
On the back edge/shoulders of the controller, you’ll find buttons to toggle video and image capture and dials that control the angle of the camera and flight speed. Two antennas are also located on the back of the device.
The antennas, two handles under the controller, and a phone holder fold out when it’s time to fly. Under the phone holder is a panel of indicator LEDs for that let you see the status of return to home, speed, video capture, and headless mode.
The controller has a built-in rechargeable battery that you can charge with the included micro USB cable.
Getting ready for flight
The steps you’ll need to do before your first flight includes charging the drone’s battery using the included charger. The drone only comes with one battery which can take up to 2hrs to recharge. That will feel like a very long time considering that the flight time per charge is only about 15 minutes.
The next step you need to do is charge the controller which will take about an hour. Luckily, the controller has a much longer battery life and should last several days per charge.
You’ll also want to install the Holy Drone app for your iOS or Android phone. The app is not required, but it does allow you to have an FPV (first person view) from the camera when the drone is paired.
Using the app
Having a first-person view helps you navigate and position the camera while capturing video. The app also has onscreen buttons that match the physical buttons on the controller.
You can also use the app to take the drone out of beginner mode and adjust settings so you can fly the drone higher and farther.
The app keeps a log of your flights so you can see info on distance flown, speed, and altitude.
There’s also a mapping feature that will let you see where you’re flying on a map.
If you have VR goggles you can toggle them on using the app and you can toggle the follow me features which will cause the drone to follow you either by flying as you move or just moving the camera to follow you while the drone stays stationary.
Up, up, and away!
Once the drone and controller’s batteries are charged, the app is installed, and the drone is paired with the controller and the phone. You’re almost ready to take your first flight. The only step left to do go through the calibration sequence which you should do each time the drone is powered up.
The sequence involves rotating the drone horizontally and vertically while paying attention to the status LEDs on each rotor. The sequence only takes a minute and then you’re ready for take off.
Pressing the dedicated take off button will raise the drone a few feet off the ground and will use the GPS to record the spot so that you can press the return to home button so that it will automatically land in that same spot or pretty close to it.
I found that flying the Holy Stone HS120D drone to be very easy and fun. The built-in GPS makes a big difference as it prevents the drone from drifting off in various directions when it’s supposed to be hovering in one spot. The HS120D is almost rock solid when it comes to hovering.
I like the one key take off and land button as well as the return to home button. Return to home (RTH) – Brings the drone back to the last recorded take-off point after you’ve used the one key takeoff/land button.
But after flying the drone for a couple of days, it decided to take a nose dive – literally.
I had it hovering overhead about 60 – 80 feet in the air and was looking down at the controller. I wasn’t pressing any buttons on the physical controller or tapping the screen. I was just looking at live camera view when I heard some buzzing and looked up to see the drone falling out of the sky. I do not know what caused it to crash like that because the battery was not low on juice and even if it was, it has a built-in feature to return to home and land when the battery is low. It was almost like the emergency land feature was triggered. To do that, you have to hold and press the one key liftoff/land button. I’m 99% positive that I did not do that.
Lucky for me that the drone crashed into the ground – instead of my head but it did suffer some damage.
I first noticed that the camera had popped off which was an easy fix. And I also noticed a small crack in one of the quad arms. But the biggest issue came the next day when I tried to fly it again and noticed that my phone couldn’t see the drone’s WiFi SSID. That meant I couldn’t use the app and the live view. I was still able to fly it just fine. I was also able to control the camera’s tilt. And I thought I was able to record video as the controller beeped continously just like it did while previously recording video. But when I went to look for the new video clips they were not on the microSD card.
I uninstalled the app and reinstalled it but no joy. I thought the crash had damaged the internal WiFi radio and the camera. I was bummed because I had planned to capture some more video clips to string together for this review. I was about to give up and then I went to Holy Stone’s website and used their live chat to tell the support person about the problem. They said that the WiFi was in the camera and to check to make sure the cables were still connected.
And what do you know, that was the problem. I plugged the disconnected cable back into the base of the drone and presto, everything started working again. WHEW!
Capturing pics and video
Here is an image that I captured with the drone. For taking static snapshots, it’s not that impressive. The images are blurry and bland.
As for capturing video, the HS120D does a good job but it’s not without issues. Check out the video below and see if you can spot the problem.
Did you notice anything? Go back and watch again and pay attention at the following times :54, 1:32, 2:22, and 3:15. See it now? The video is dropping frames. At first, I thought this problem was due to the damage that the drone had sustained in the 2 crashes. So Holy Stone sent me a 2nd brand new drone. Unfortunately, it had the same issue so it’s some type of glitch in their software or hardware.
You’ll also notice that footage can look a little jerky when you start to fly or stop. The drone has a lot of power and when you press the joystick to go forward, it does just that and it can dip the whole drone forward. Then when you stop it tips the drone up sort of like what happens when you slam on the brakes of your car.
What I like
- Easy to fly
- GPS feature allows great hovering in place
- One touch fly/land buttons and return to home buttons
What needs to be improved
- Would be nice to include 2 batteries
- Fix video frame drop problem
Final thoughts
I’ve reviewed or tested several drones now and the Holy Stone HS120D is my favorite inexpensive drone. It’s easy to fly and has a great altitude hold feature. As long as it doesn’t decide to plummet from the sky for no reason like mine did, it’s fun as heck to fly. It doesn’t have a 4K camera and it has a strange frame drop issue, but at only $170, you can’t it to be as good as that other brand. As is, the Holy Drone HS120D is at the top of my list for an affordable drone that’s easy and fun to fly.
Price: $169.99
