Appearance

Motors

Camera

On board the Udi U818A quad, a simple VGA camera is installed, which cannot boast of the quality of photo and video recording. Shoots both stills and videos in 640x480p resolution. The main purpose is the initial acquaintance with the process of aerial photography by means of UAVs. If desired, the camera can be changed to a more technological one, which, in general, will significantly extend the time to get positive emotions from owning a quadrocopter.

The Udi U818A is currently being released with a new HD camera that captures video in 1280 × 720p resolution. In this connection, the abbreviation "HD" - Udi U818A HD was added to the drone labeling.

Battery

Control

The Udi U818A quadrocopter is controlled by a classic transmitter operating at a frequency of 2.4GHz. Provides a distance of up to 60 meters in an interference-free area. Power is supplied by four 1.5V AA batteries ​​(purchased separately).

Button Assignments

Test drive

In the niche it occupies, the Udi U818A showed good dynamics in the absence of wind. In practice, in windy weather in flight, the quadcopter had a noticeable windage. Note the operation of the 6-axis gyroscope, it is indicatively stable in control, beginners will appreciate it. Has 2 modes of activity. In our opinion, the developers, using this model as an example, focused the attention of a potential buyer not on the dynamic properties of the drone, but rather on the UFO design. The drone is especially effective at night in the beams of LED illumination.

Price

On various Internet trading platforms, the price for the Udi U818A quadrocopter starts from $ 40.
