Our partner has sent us two very similar drones, especially considering the price level. In both cases, you can get a very interesting quadcopter for $100, but each of them with a bit different utilization. What’s the purpose of each drone and how did they hold up during our testing?


One would expect that JJRC X1, which is twice the size of XK X251, would be packed in a double sized box. However, it’s quite the opposite. See for yourself.

When we started unpacking this device, we noticed another difference immediately. XK X251 is firmly secured in polystyrene so when it’s on its way to a costumer, there won’t be any damage caused to it, most likely. Unfortunately, JJRC lies on a cardboard structure on which all the components are placed so precisely that you would probably have a hard time packing it up all again. One of the reasons why JJRC wraps their drones into the smallest box possible can be, for example, the drop of the shipping cost. A huge disadvantage is that you have to manually attach all the accessories necessary for full functionality of the drone, using the screws. Therefore, if you would like to keep the drone in the box, it would be necessary to detach the accessories every time. In the case of XK, manufacturer did it all for us so when it comes to storing it, no problems will occur.

We are quite satisfied with the accessories. In both cases, there’s everything we need in the basic package, except AA batteries for transmitters.

You can watch unboxing of the drones here:

What really amused us was the elaboration of the manuals. There’s no correct English and relevant info is missing, which can be disappointing. We had to check the manual because we didn’t know how to bind JJRC X1 with the transmitter. However, we didn’t learn a thing from it so we had to search the internet where we, thank God, found the info on how to do it.


When it comes to design, it all comes down to the preferences of an individual. I personally like the combination of black and blue more, which is present on JJRC X1, but XK X251 doesn’t look bad either. If you’d like to think about it deeply (sure we have done it too) and compare the drones’ look to various insects, JJRC X1 reminds us of a peaceful dragonfly, while XK X251 a small, aggressive wasp.

Enough poetry, let’s rate the practicality and durability. The body of XK seems, even at the first sight, very stable. Its arms and landing bars are made of carbon fiber which assures good durability as well as light weight. JJRC is made of plastic which will probably survive usual crashes (survived ours), but still seems very fragile.

However, when it comes to battery covers, JJRC definitely does better because the battery is perfectly hidden there – not exposed to any danger. But it’s quite difficult to close the (battery) slot because of the connection wires. In the XK case, the battery sticks up a bit and the connection wires are pretty exposed. Overall, the battery mounting itself doesn’t look very reliable.

I really like the propeller protectors JJRC comes with too.


The XK transmitter is just amazing. Its material is very solid and it has a display. JJRC lags behind in this case. The quality of the transmitter is poor – seems rather like a transmitter for a cheap toy bought in a shop nearby.


JJRC is equipped with four 2280 kV brushless motors type D1806, while XK has 3000 kV brushless ones type 1307 – that enables it to reach high speed, we could even perceive it as a racing drone. With XK, we can also switch between 3D and 6G mode and tell which mode the device is in by looking at the LEDs at the back of the drone. The stabilization is assured by the integrated 6-axis gyroscope.

You don’t have to be afraid to fly in the dark with the LEDs at the bottom of the arms, however, JJRC’s ones don’t shine that bright like XK’s. Neither of the drones is equipped with a camera in the basic package, but if somebody would insist on it, they can buy it and easily attach there.

JJRC has a little bit stronger battery (1300 mAh) and it enables flight lasting for up to 15 minutes, however, the difference is not big. The XK’s battery has the capacity of 950 mAh and can stay in the air for just 2 minutes less. After approximately an hour and half of charging both of them, the drones are ready to take off.

If we should talk about the transmitters, you’ve probably already noticed, based on looking at our photos, that the XK’s one seems more reliable. A huge advantage is the small display too. Both transmitters operate at the same frequency – 2.4 GHz. JJRC claims that the range of X1 should be 400 meters which is awesome, but we were too scared to check it, because we’re just beginners. However, the range of XK – 300 meters – is a nice number too.

If the batteries of the drones are charged and those for the transmitters are bought (XK – 6 x AA, JJRC – 4x AA), the fun can begin.

The way of binding is different for each of them and we have to admit that the JJRC’s way is very original and unprecedented – we wouldn’t get it without checking other reviews online.

XK’s binding is simple – first, you have to make sure that the throttle is down (see pic 1), then it’s important to connect the battery to the drone which turns it on, start the transmitter where you must not have the HOLD.T on (the right upper handle must not be down) or 3D mode (the left upper handle must not be up) and you just press the binding button on the drone (see pic 2) for one second. Then it’s done.

As we’ve mentioned, JJRC’s binding is a funny thing. First, you have to turn the drone on by connecting appropriate wires, after that you switch the transmitter on and move the THROTTLE and ELEVATOR (see pic 1) down and immediately to the outer bottom corner (see pic 2) and hold them until you hear a beep sound, then you let the ELEVATOR go and start moving the THROTTLE from the left bottom corner to the right one. If you manage to do it right, the propellers will start spinning which means the drone is binded.

After a couple of attempts, flying both drones was alright – that’s why they are an ideal choice for beginners.

However, when we first tried XK, it flew up in such a speed that in seconds, we were seeing only a dot in the sky. Despite that, we managed to land the drone with no problem and even though we were searching it on a huge field for an hour, everything was okay in the end. So just be careful! This device’s motors are so strong that any kind of weather doesn’t affect the drone’s functionality – thumbs up for that.

SKU236948_1Too bad is that we lost one of the motor nuts (M4 CCW) during the second attempt. The drone was incapable of taking off then. As we browsed through the internet, we found out that we were not the only ones who had faced this issue, although, the manufacturer doesn’t sell this item separately. Due to that, we will have to buy a whole new motor. Make sure that all the screws are tight every time you want to take off. Due to these complications, we we’re not able to record a video capturing the drone’s flight, but we’re going to fix it as soon as the device is okay.

JJRC flies just great. Watch the video, but please keep in mind that we are only beginners incapable of any acrobatics yet.



Each of these drones has a different purpose. As we’ve mentioned before – JJRC X1 is like a peaceful dragonfly, while XK an aggressive wasp. It’s reflected on the way the drones fly. You can fly with JJRC at a slow pace and relax, however it’s impossible in the case of XK because that drone is just freaking killing it!


The same price level but different results. I hope you believe me now. If you didn’t know which one to buy before reading this review, I hope we helped you decide. We enjoyed XK X251 more, cause even at the first sight, it just seems very durable and reliable. The transmitter just amazed us and the binding is pretty simple. JJRC has its perks too, for example a greater range, flight time and last but not least – the motor nut/ cup didn’t fall off during testing.

We would like to thank again, because those guys lent us both the drones. You can buy both XK X251 and JJRC X1, there.

We are looking forward to seeing your opinions in the comments section below and if you’ve thought of a piece of information the review lacks, we’ll get inspired and add it.
