JJRC H37 Elfie Drone Review - An Affordable Smartphone Controlled Drone


Normally when it comes to drones, we all expect all drones to be very expensive but there are actually a few drones that are budget friendly with specifications that are not too bad.

Highlights Of JJRC H37 Elfie Drone




  • Portable / Foldable Design


  • APP control (G-sensor and virtual sticks);


  • Wi-Fi real-time image transmission;


  • Altitude hold (auto-hover);


  • One key return-to-home (not GPS);


  • Headless flight mode;


  • Multiple flight speed rates (30%, 60% and 100%);


  • About 8 – 15 minutes of flight time;


  • Near 100 meters control range in open field.




  • I got my hands on a H37 drone review unit (thanks to PrimeHomes ) and I spent 3 days handling the mini quad-copter drone and I'm quite impressed with the drone.


    What's In The Box?

    The drone comes in a portable box. There's nothing to flashy about the packaging so I'll go straight to what's inside.



    Inside the box, you've got the Elfie Drone, USB Charger that looks like a Flash Drive. I actually thought it was a flash drive before I actually brought it out and examined it properly.




    There's also the Instructional Manual, a velvet pouch and an extra set of propellers just in case something goes wrong during the flight and any of your drone's propellers gets damaged.




    Battery



    The JJRC H37 Elfie Drone comes with a 500 mAh LiPo Battery. The first time I opened the back of the drone, the battery wasn't plugged in and I found it a little bit difficult fixing it correctly the first time but after fixing the battery about 3 - 4 times everything got quite easy.



    What I don't really like about the battery is the fact that you have to remove it from the drone and charge it separately. Try to be careful when you're handling the battery so you won't end up cutting the wires while trying to unplug it.



    The battery takes about 15-25 minutes to charge fully. Once the battery gets low, the drone would automatically shut down when you try to lift it off so you have to plug it in with the charger.



    Once you plug it in the USB charger displays a red charging light and stops displaying once the battery is full.



    Camera

    The camera is a wide range 0.3MP camera. Wi-Fi FPV allows the drone to capture photos and videos with resolution of 720 x 576 pixels. Recording up to five minutes of video only takes about 23 MB. All pictures and videos are stored directly on your smartphone hence there's need for an SD card.

    You can find the video files are stored in the VS FPV folder.


    The camera’s real-time video feed can be displayed on your mobile device (smartphone/tablet) through the VS FPV App or in the folder of the app recommended by your manual.


    Note : Your Drone Manual may ask you to install a different App. My review unit requires VS FPV.


    Images Taken From The JJRC H37 Drone








    First Flight



    Before your first flight, you need the install the APP recommended on your manual on your mobile device. After unfolding the arms, power ON the quad and look turn on the app and connect to the drone's wifi Hotspot. (It's usually an open WiFi network)

    In the case of mine it's "trust-toys-6cce69"



    Once it's connected launch the app and tap on connect. You should see the live feed and the virtual joysticks displaying above the feed. Select On to turn on the drone. Usually, by default the propellers are automatically set to be in idle mode so you have to tap on the icon that's located on the right side of the drone speed (the one displaying 30 is the drone speed)




    Once you're done, push up the throttle stick (left one) and the drone will start to rise. Please use your manual if you don't understand. Trust me I tried flying the drone without reading the manual properly and I couldn't even control it.


    I don't recommend flying indoors if you've not gotten used to the controls. It's best you start outdoors.. Also I recommend you leave the default speed at 30 until you're perfect with it.

    In case of emergency you can use the “Stop” button, this will stop all the motors instantly.

    Here's The Flight Test Video :



    JJRC H37 Flight Control

    You can control the drone in two ways, using the virtual sticks or through gravity sensor by tilting the phone. Basically the JJRC Elfie H37 can be controlled just the way you play a mobile game,


    When you want to land your drone, you just need to press the arrow-down button, and the drone will land and stop its motors.

    Common Issues With The Drone

    Of course I won't say I didn't have my own share of technical mishaps when using the drone.


    1. Drone Keeps Flying To One Side.

    It means it's miscalibrated and you need to recalibrate the drone. Place it on a flat surface and connect it to your phone and launch the app. Turn on the drone, go to settings (gear icon) and select calibration. ( it's the last icon on the settings menu). When you do this, the drone's front and rear LED lights would blink continuously for about 7-10 seconds. Once it's done calibrating your drone is ready to fly.

    2. Drone Not Turning On After Crash Landing

    Unplug the battery and plug it in back.

    3. Drone Goes Off When It's About Taking Off
    The battery's probably low so all you have to do is to charge the battery

    4. Camera Feed Not Displaying On Your Phone

    Simply close the app (don't minimize it). Turn off your WiFi and turn it on again. Once you're reconnected to the drone, launch the app and connect. Everything should be okay

    Verdict 💡

    I'd say the drone is pretty good and one of the best at this price range, however I'm not okay with the fact that you'll have to keep unplugging the battery to charge it and the lack of an obstacle sensor makes it a little bit difficult to handle in enclosed areas but anyone that can handle this drone perfectly would certainly have no problems handling the ones with obstacle sensors.

    Rating - ⭐⭐⭐ (3/5 stars)
