Holy Stone X300C Review

The Holy Stone X300C is a high quality FPV quadcopter,which has all the features you need to start first person view flying. It’s durable, has prop guards, can do flips on button press, and the live video can be viewed on Android and iPhone smartphones too.

The X300C is 6 axis stabilized, and the flights are very smooth.

The range is around 50 meters, and the X300C can fly just as high too. Just as other quadcopters using the 2.4Ghz technology this one will crash too once out of range, so take care.

The WiFi range for the camera is around 30 meters.

The X300C is not only very durable, but it’s very easy to fix too would things go wrong. Official replacement parts are available and the arms holding the motors and propellers can be simply popped of for the repairs. Replacement batteries are available too.

The quadcopter weighs around 100 grams, so it can only lift small object,for example a key chain camera for additional video.

The X300C is suitable for both indoor and outdoor flights, and has three levels of control for beginner to intermediate pilots. Beginner mode is exceptionally good for indoor flight. Additionally the transmitter has a button to set the throttle limit.

The quadcopter flies well in small gusts, but stronger winds can carry it away.For best results choose calm days for outdoor flights. Flight speed is good too, can even be scary when view through the smartphone app.

The product is marketed for age groups 14 years and up. The X300C contains small parts which little children could eat, so keep it out of their reach.

The Holy Stone X300C has basic “return home” functionality, which means that it will start to fly towards the transmitter on button press, all this without a GPS. It has headless mode too, which is very rare in this price category, and makes the X300C unique. The headless mode means that the X300Cwill remember it’s liftoff direction, and the forward-backward-left-right sticks will work compared to that direction, not the X300C’s actual direction. It’s a really handy feature if you feel you lost the orientation.

The X300C is around 23×23 cm and the weight is around 100 grams. Such light quadcopters do not have to be registered with the FAA, which is a plus.

The X300C has bright LEDs which help with the orientation, and they are also good for night flying.

The box contains everything for flying, except for the 3 x AAbatteries for the transmitter and weighs around 2 pounds. The size is about46 x 8 x 30 centimeters. As a bonus you even get a second battery.

The motor is coreless brushed, and the drive train is geared. However theX300C flies very silently.

Flight time is 10 minute after a 90 minutes of charging. To avoid overheating let the X300C rest 10 minutes between the flights.

The transmitter

is full sized, not the toy like-transmitter you’d get with most other quadcopters. It uses the interference-free 2.4 Ghz technology, so you will be able to fly together with others.

The X300C can only bind with it’s own transmitter.

For the FPV flying the transmitter has a smartphone holder too, which is really handy.

The transmitter supports mode 1, 2, 3 and 4 too, so you are covered whichever you prefer. There are two buttons to select throttle stick, one button on the left of the left stick and the button on the right of the right stick. Sliding both up will select the right stick as throttle,sliding both down will select the left stick as throttle.
To switch aileron and rudder, push the lower button left of the LCD.

The X300C and the transmitter auto-bind, all you have to do is make sure both the X300C’s and the transmitter’s batteries are fully charged, and theX300C is resting on an even surface when you turn it on.

The range is about 50 to 100 meters.

The X300C’s video

is a 2 megapixel (720p) live camera, and Android smartphone or an iPhone is necessary to use the video functionality. The transmitter has a camera holder which makes using the Tx and the phone together easy.

The camera is fixed in the quadcopter’s housing, so there is no way to move it around.

The smartphone app has the buttons to take photos or start video recording.

Using the app is simple: first search for the WiFi network starting with “MJX C4005 FPV”and connect to it.
Next start the Holy Stone mobile app, and select “Monitor”.
There is a mobile app for the iPhone, while the Android app is available on the Holy Stone website.
In the Google Play store the MJX RC FPV C4005 and the SYMA-FPV apps are compatible with the X300C.

The WiFi range is around 30 meters, so WiFi will drop out before the quadcopter flies out of transmitter range.

The photos and videos are recorded exclusively to the smartphone via WiFi, so that’s where you will find them. The X300C comes without an SD card or SD card slot.

The smartphone apps support viewing the recorded videos and photos too. The videos and photos are stored as files on your phone, so you will be able to download them as you wish.

The photos are high quality, and the video is good too, depending on how faraway you are. The only downside is that the video lags, which makes FPV flying difficult. However the X300C is great for non-FPV use because you can actually see what you are recording.

The X300C’s battery

is a 3.7 volt, 750 mAh Li-Po battery which grants the X300C a 10 minute flight time after 90 minutes of charging.

The charger is USB based, however it’s advised to use a 0.5 Amp USB socket only (your computer’s USB socket will work perfectly), otherwise you may fry the charger.

Charging is easy: plug the battery into the charger, then the charger into an USB socket. Charging is finished when the red LED turns on.

The battery uses a JST plug, so you charge it with any JST based charger,and the quadcopter is compatible with other 3.7 volt LiPo batteries with a JSTplug too – just make sure it fits into the quad.

Upgraded batteries with charger are available too.

The X300C has low-voltage cutoff, the flashing LEDs will tell you it’s high time to land. It’s also a wise to monitor your flight times, so you are prepared to land once the battery is expected to run out.

If you plan to store the X300C for a long time, it’s a good idea to fully charge the batteries beforehand – they last longer this way.

Overall

the X300C is a great quad for getting started with basic FPV flying, however it’s a bit picky: it needs about 10 minutes of rest between the flight to avoid overheating, and the factory charger can only cope with 0.5 Amps. The video has a slight lag too.
Fun:★★★★☆
Value:★★★★☆
Looks:★★★★★

Here is the X300C manual. RCGroups has a thread on the MJX X series; the MJX X300C is the same as the Holy StoneX300C. If you like small quadcopters with a camera, you will surely like the Holy Stone F180C and the Hubsan X4H107C. These do not have FPV, but their cameras are better.
