Kai Deng K70C Sky Warrior Review

The Kai Deng K70C Sky Warrior is a camera quadcopter released earlier this year.

Even though it’s an older model, it’s still a cheap drone capable of filming with a GoPro. You can even adjust the GoPro (or other action camera) angle straight from the transmitter. Cool stuff.

Let’s take a closer look at this drone’s features and how well it performs.

Flight Performance & Rates

The Kaideng K70C has three different flight rates.

It flies very smooth and precise in each of these flight rates. In the 1st flight rate, the quadcopter is slowed down greatly. This makes for very smooth and stable flying, perfect for filming.

The highest rate, on the other hand, is much faster. I’m surprised at how sporty this quadcopter flies for a camera platform. It can make sharp turns, even up to a complete 180-degree turn almost instantly. It has brushed motors and flies very similarly to the Tarantula X6 which is often noted as one of the most powerful toy-grade quadcopters.

One minor downside I have noticed is that there is a bit of a dead zone in the center of the control sticks. Sometimes you really need to push the sticks heavily before you start to see the expected movement. This can make flying feel unresponsive at times, but overall, flight is a great experience.

Here’s a video of a Kai Deng K70-C flight test:


The K70 is a rather large quadcopter. It has arms that reach back, with crazy blinking LEDs that shine through the back arms. They make for great visibility for night flights at dusk or when it’s dark out, but they’re not very visible during daylight. This is a shame because orientation with this quadcopter tends to be a little difficult at times, and visible LEDs would make it that much easier.

It includes 4 prop guards which require 2 screws each to install. This is a bit of a nuisance, and to be honest, the prop guards seem to be more trouble than they’re worth. Especially with larger quadcopters, I feel the prop guards just increase the odds that your drone will get stuck in a tree in case of a bad crash.

Lastly, it has two light but sturdy landing legs which reach under the camera mount. They are also rather tall, so they lift the quadcopters propellers over grass quite easily, meaning you can take off from nearly anywhere.

Can The K70C Lift a GoPro?

The most asked question about almost any camera drone is “can it lift a GoPro”? Not only can the K70C lift a GoPro, but it’s mount fits a GoPro 4 near perfectly. It also fits other action cameras, such as SJCam, Xiaomi Yi, etc. Keep in mind that the heavier a camera is, the more strain it will put on the quadcopters batteries and motors. This will not only decrease your flight time but also wear down your motors and require replacements more often.

Since the K70 is a brushed quadcopter, it’s not really designed to lift a camera as heavy as a GoPro. So to answer the question simply – yes, it CAN be used to film using a GoPro… But I don’t recommend it. You’ll be replacing motors too often for it to be worthwhile, in my opinion, and you’re better off looking for a more GoPro capable quadcopter if that’s your only requirement. I suggest you take a look at our previously reviewed Bayangtoys X16 instead.

Here is a video of the K70C lifting a GoPro Hero 4:

Stock Camera Quality

The included camera mount is unique in the sense that you can control it’s angle straight from the transmitter. This is convenient since you won’t need to manually adjust the camera mount by hand every time you want to film a different angle. You can angle the camera all the way forward or all the way down for overview filming. Overall, this is a VERY convenient feature that makes this quadcopter stand out from its competitors.

The camera itself, on the other hand… Is not so great.

It’s pretty much your standard cheap toy-quadcopter camera. Advertised as 720p but it’s quality really resembles that of a flip-phone from the early 2000’s. The video coloring is washed out and there is a wobbly-jello effect due to the lightness of the camera. Heavier cameras tend to reduce the jello effect more, especially with this specific quadcopter.


Kaideng K70C TransmitterAs spoken about before, the transmitter’s main feature is that it can adjust the camera’s angle. This is done by hitting up/down on the throttle trim button which is located directly right of the throttle stick. Pressing up will move the camera angle forward and pushing down will angle the camera downwards.

Aside from this neat feature, it’s pretty much you standard cheap plastic transmitter.

It has your typical trim, headless mode and return to home buttons. Of these, I only ever use the trims to level out my quadcopter when needed, but the headless mode and return to home are near useless to me as they don’t do anything that you can’t do by controlling the quadcopter manually.

Of course, like most toy quadcopters, there is a button for flips, which the K70 admittedly handles very nicely.

Lastly, it’s possible to recalibrate the accelerometer if your K70 feels unbalanced for whatever reason. This is done by placing the quadcopter on a flat surface and holding both control sticks down to the left for a few seconds. This helps stabilize the quadcopters accelerometers which sometimes tends to go out-of-whack.

Battery & Flight Times

The included battery is a 2s 2000 mAh LiPo. It takes nearly 3 HOURS to charge and offers flight times between 8-9 minutes with the stock camera.

Removing the camera will grant you an extra minute or so of flight, and adding a heavier camera will decrease the flight time depending on exactly how heavy the attached camera is.

Final Verdict

Overall, the Kaideng K70C is a fantastic quadcopter. Being able to adjust the camera’s angle directly from the transmitter is a rarity for this price, and the potential to film using a GoPro without any modifications is the icing on the cake. Sure, it may not be the best choice when it comes to GoPro drones, but it is certainly capable of getting the job done.

If you want a cheap quadcopter capable filming with a lighter action camera such as an SJCam or Xiaomi Yi straight out of the box, I’d say the K70C is a pretty good choice. If you’re looking for something that will work with a GoPro, personally, I’d opt for something that would hold up better in the long-run, but yes, it is possible to use this drone for it.
