UDI U818A Quadcopter Design

The UDI U818A is similar to many other quadcopters in design, with a plastic cross frame and pretty much entirely plastic parts. It is a mid-size quadcopter, measuring about 13″ by 13″ and about 2.5″ tall. If you’re familiar with the Syma X1 quadcopter, it is nearly identical in size – and has very similar propellers too! Personally, I think this is a great size quadcopter to learn on as it is big enough to see easily, it can be controlled with easy and isn’t too twitchy like some micro/nano quads, and its still small enough to fly indoors.

The motors are standard and the drive assembly is exposed just like in the Syma X1, so you can see the gears that drive the propellers. Be sure to check them for hair, dust, etc. after a few flights as that can interfere with your performance and its best to keep it maintained and free of debris before it becomes an issue.

Like most quadcopters in this price range, the lithium polymer battery slides in a compartment on the bottom and you manually connect the wires together. Having a swappable battery is a big plus, though I do hope that at some point manufacturers turn towards batteries that clip into place, i.e. as in the Parrot Rolling Spider MiniDrone. There are four LEDs that illuminate the bottom of each propeller/quadcopter arm, two in the front that light up blue and two in the rear that light up red. This can be very helpful when you’re flying to help you orient the aircraft, and additionally, there’s a bright white LED right on the front of the quadcopter that also helps you know which way is facing forward.

Surrounding the body of the quadcopter is a fairly solid, but somewhat flexible, plastic bumper that protects the propellers from damage. While this adds weight and restricts your maneuverability a little bit, this integrated bumper is very helpful for indoor and outdoor flying. A crash that may have resulted in a broken propeller or damaged frame on a Syma X1 would probably just be a minor scuff for the UDI U818A quadcopter.


The U818A is very easy to fly and performs just like any other quadcopter in the same size range. It is responsive, surprisingly stable for the price, and does well in (very) light wind conditions outdoors. The UDI U818A is able to do flips and inversions, which are easily performed via the buttons on the remote. Overall, it is a fun quadcopter to fly and has a very easy learning curve.

Camera, Video, and Photography

One of the best features about the UDI U818A is that it is video and photo enabled right out of the box! It has a small video camera integrated into the bottom of the quadcopter, and no additional tinkering is necessary to take videos and pictures.

The camera has a resolution of 640×480 pixels, which is not HD but is still useable and produces a decent picture. Of course, with any camera and sensor of this size, the quality of the picture is going to leave something to be desired. At this price point, you can’t really expect to have an amazing picture, but for what it is it isn’t all that bad. As one reviewer put it, “the quality of the camera is like a cell phone camera from six years ago.” The videos and pictures are stored on a microSD card that is inserted into the back of the camera module.

Battery and Charging

The UDI U818A quadcopter comes with one 5oomAh Li-Po battery, which is the standard type for this size of quadcopter. The battery will give you about 7 minutes of flight time, which is not really that great, but also not particularly short either. The battery does take a while to charge though – the manual and documentation states 120 minute (two hours!) but I got about 1.5 hours. Still, that is very high for this size of battery/quadcopter so I would definitely recommend that you purchase multiple batteries and have them pre-charged before you want to go out and fly.

Remote Control

The transmitter is a solid size and has a good weight in your hands. It has an LED to indicate On/Off, it has buttons on the top left to assist with flips and maneuvers, and it also has two buttons on the lower left face of the controller to activate the video and/or photo modes. Additionally, you can select the High/Low speed with the lower right button on the face of the controller. It takes 4 AAA batteries (not included) and will enable you to control the quadcopter up to about 100 feet (30 meters). Another great feature in the transmitted is the integrated monochrome LCD display that shows information about the battery, trim levels, and video/photo status. You can also turn on and off the white LED lights on the quadcopter.

UDI U818A Review – Final Verdict

The UDI U818A quadcopter is a solid value for anyone looking for their first quadcopter to learn on. The integrated video on a quadcopter of this size is a very nice selling point, and its ease of flying and stability make it a strong contender in the consumer quadcopter market. The integrated bumper will help anyone who is just learning how to fly, and as you become more advanced you can also remove the bumper and fly without it (thus increasing your flight time and maneuverability). We highly recommend the UDI U818A quadcopter and we’ve featured it on our best quadcopter page.

UDI U181A vs. Syma X5C – many folks may ask, is the UDI U818A or the Syma X5C quadcopter a better deal? The UDI U818A is a bit larger than the Syma X5C, but they both offer similar capabilities and features - and both are easy to fly and great quadcopters to learn on. Both quadcopters are excellent choices and will provide hours of entertainment!
