Cheerson CX-OF quadcopter review

Cheerson CX-OF quadcopter

The Cheerson CX-OF quadcopter, with optical-flow sensor and intelligent flight modes, changes the rules. Of course, besides all these, it’s equipped with a WiFi FPV camera which allows to enjoy first-person view flying using your smartphone.

The CX-OF is a great successor of Cheerson Hobby’s CX-10 Nano drone series. It incorporates all the features of its predecessors and many cool extras. Frankly, it is a miracle how they succeed to integrate so many functionalities into such a miniature flying machine.

Cheerson CX-OF drone review - Introduction

Cheerson announced the CX-OF in two package variants. RTF (Ready to Fly) with included transmitter and BNF (Bind and Fly) without RC. Both version have two color options – Red and Blue. Perfect for girls and boys 🙂

Cheerson CX-OF quadcopter review

Disclosure: I received this drone as part of a product review collaboration with Geekbuying. Although the product was offered for free, all opinions in this article remain my own and I was in no way influenced by the sponsor.

This time I need to be a bit more expeditious with my review because the package included two more quads that are waiting to be tested 🙂

1Cheerson CX-OF review: At a glace

Cheerson CX-OF drone review - Box content

Inside the box, besides the tiny aircraft and its surprisingly stylish transmitter with phone holder I found the following: a complete set of spare propellers, USB charging cable, micro USB cable, blade removing tool and English instruction manual.

Probably many will consider the paint job on top of the aircraft childish, but I actually like it because reminds me about my favorite action-horror movie, the Resident Evil.

The aircraft measures 40 * 40 * 35 mm and weights about 24 g. Quite small you might think, but just perfect for indoor fun.

On the bottom part is located the optical flow sensor, which actually seems to be a 2nd minuscule camera. According to the specs, the sensing distance is about 3 ~ 4 meters.

In order to allow better view on the orientation of the aircraft, in front has blue propellers and white ones on rear. During night flights, you will be guided by 4 tiny LEDs (blue in front and red on rear).

2Cheerson CX-OF review: Camera and WiFi FPV

Cheerson CX-OF drone review - Camera

As you can expect from such a small toy, the camera is integrated and does not allow any angle adjustment.

The camera allows to capture photos and videos with resolution of 640 x 480 pixels. Two minutes of video occupies about 5 MB. The captured files are stored on smartphone’s flash memory, in the folder named “Drone”.

Image quality is pretty good for such a small toy, but nothing impressive. Frame rate is only 16 fps. Definitely, your selfie videos will not be crispy as shown in advertising videos.

The camera’s real-time video feed can be displayed on your mobile-phone through the “CX-OF” APP. The application is available for both popular mobile operating systems (iOS and Android). FPV range is about 20~30 meters.

3Cheerson CX-OF review: Remote controller and Mobile APP

Cheerson CX-OF review - Transmitter

Cheerson Hobby opted to completely redesign the transmitter compared to the predecessor model (find more on my CX-10WD review). The RC is no more expandable but still conformable for kids as well as for adults.

The remote controller is powered by built-in 120 mAh battery, which can be charged conveniently with the included micro USB cable.

Besides the usual control sticks (both centered in the middle) and power switch, there are only 4 buttons (Take off, Land, Speed switch and 3D flips). No shoulder button nor trimming switches.

Additional to the physical remote controller, you can opt to control the aircraft through your smartphone – using gravity sensor or virtual sticks.

Through the APP you can also access the intelligent flight modes. There are few preset dancing choreographies that you can play with.

4Cheerson CX-OF review: Test flight

Cheerson CX-OF drone review - Indoor test

When it comes to drones as small as the Cheerson CX-OF-TX I recommend for newbie pilots to practice indoor first. Outdoor, the slightest breeze can take away their new toy.

Starting the flight is very simple, after binding you just need to push the “Take off” button. The aircraft raises for about 1.5 meter and waits for your controls.

Thanks to the optical flow sensor, the Cx-OF quadcopter is more stable compared to its predecessors – which is essential for taking selfies. BTW, the sensor can be disable by long pressing the “H/L” button.

The built-in 150 mAh Li-Po allows about 4 minutes of play time. When the battery is near empty the quad will land automatically.

5Should I buy the Cheerson CX-OF?

Cheerson CX-OF drone review - Verdict


Certainly, the CX-OF is currently one of the most versatile toy drone. Unfortunately is also one of the most expensive mini quad.
It is extremely easy to pilot and features multiple control modes. Kids will love to control it through their phone G sensor.
Hovering stability is superior to any of other similar drones that I reviewed.
Dancing and trajectory features are nice but, frankly, not for veterans like me.
