UDI U818A indoor & outdoor flying review

It will be possible to fly this quadcopter both indoor and outdoor, as long as the wind condition is gentle. It is capable of flying or hovering in any direction, whether backwards, downwards, forwards, rotating left and right, suspension, and upwards. Since a 6-axis gyro has been built into this quadcopter and gyro sensitivity can be adjusted, so extremely stable flight is ensured.

Challenging to fly & easy to charge

If you have previously enjoyed the experience of flying a smaller quadcopter, then the UDI U818A quadcopter review will show you that you will certainly relish the challenge of flying this large-sized, 33 x 34 x 5.5 cm (13 x 13.3 x 2.2 inches) UDI U818A. If you are new to flying RC aircrafts, then this quadcopter is ideal for you. It can be charged quite conveniently through a laptop or notebook, or the included USB cable.

3D flight & 360 flips

Apart from the typical flying movements, 3D rolling action can also be performed by this quadcopter. Professional 3D maneuvers are simplified due to the fact that this quadcopter maintains agility and stability in flight. In fact, with sufficient practice, it can also become possible to fly one loop after another at a time, rather than just one.

4 channel remote 2.4GHz controller transmitter


The 2.4GHz spread spectrum technology is adopted by this model, which gives it the attributes of longer control distance, minimal power consumption, quick response and strong anti-interference ability. 2.4GHz is a new generation radio system that has become standard for RC aircrafts. As a result, interference and legal issue are reduced, and stable radio transmission and transmission distance are increased. Generally, the problem with traditional radio frequency is that interference of two RC helicopters in the same frequency can prevent both of them flying.

Comparison between UDI U818A and Holy Stone U818A drones

The Holy Stone U818A and the UDI U818A are little drones in the same league. You may be searching for a small drone that does awesome flips, yet has the features of a more advanced quadcopter.

Both drones can capture images, but one does so better than the other. The Holy Stone U818A HD Plus drone with camera 2.4 Ghz 4 channel 6-axis gyro quadcopter comes with a 2MP HD camera that can capture stellar photographs from the air. The UDI U818A has a functional camera as well. However, it cannot capture high-quality photographs and videos. That said, it has an FPV (First Person View) feature that allows you to view your footage as you capture it.

holy stone U818ABoth these tiny drones can do engaging flips and rolls. Despite their outstanding flying acrobatics, they come fitted with 6-Axis gyroscope technology, which keeps them stable.

The Holy Stone U818A HD Plus quadcopter drone trumps the UDI 818A when it comes to tracking features. It has a Headless Security function which prompts it to return to its take off point when it runs out of battery, or gets lost.

Both drones do a fine job of flying, tracking and capturing aerial images. The Holy Stone drone, however, does it a bit better than the UDI U8181A.
