Specification

Appearance

Motors

Equipped with collector motors. The transmission of torque is realized through a closed-type gearbox. The developer does not disclose performance information. They work in tandem with wear-resistant rotor cores, which now include nylon. There is enough potential to realize a stable and controlled flight even in windy weather.

• X5UW-D powerplant regulators with automatic anti-jamming and overheating protection (motors stop if something interferes with their work).
• The user has 2 drone activity modes (50/100%).

Camera

Onboard 1MP Wi-Fi HD camera, the lens of which received eight optical elements

Photo / video recording can be performed both on the microSD card pre-installed in the camera

FPV

First person flight for the X5UW-D quadcopter is implemented via Wi-Fi, via a video transmitter working on frequency 2.4GHz. The display of the picture in real time is carried out through the mobile application "Syma Fly" (for IOS / Android). In practice, it was noted that the broadcast quality improved, but the delay, which increased as the drone was removed, remained a key disadvantage of the model. For a comfortable FPV flight, an interference-free zone is required, and the removal distance should not exceed 10-15 meters. Video stream resolution 720p.

Power supply

Power supply remained unchanged - 1S 7.4V 500mAh LiPo, principle of battery replacementa docking station

The modified Syma X5UW-D now does not fall when the battery is insufficiently charged, but performs an automatic landing.

Control

The set includes the same 4-channel control equipment operating at a frequency of 2.4 GHz. To implement remote camera tilt angle change (0 ° / -15 ° / -45 ° / -90 °), two additional buttons have been added. Thanks to the included holder, for the purpose of comfortable piloting the drone in the first person mode, it can be combined with a smartphone. According to the specification, the remote control provides a removal distance of no more than 70 meters. In practice, in a megalopolis, this distance is halved. Powered by 4 × AA

Syma X5UW can also be controlled:

• Smartphone (via the downloaded Syma Fly application)
• all functions will be active)

Key assignment

Positioning and altitude hold

The trademark of Syma X5UW-D is an optical sensor located on the bottom of the drone to the left of the camera

The optical sensor positioning process consists of sequentially acquiring ordered images and calculating the displacement using the optical flow method.

Flight Plan function

Thanks to the Flight Plan function, the aircraft can fly along the drawn route.

To execute the function, you must:

1. Launch the quadcopter in Altitude Hold mode
2. Activate the Flight Plan function. The gadget will display a map with a zoom slider (to display a map, the application must have access to the location of the smartphone).
3. Simultaneously with the map, the left side of the screen will be occupied by one digital stick responsible for controlling the drone (Left / Right / Forward / Backward).
4. Based on the map of the area, a flight path is drawn on the smartphone screen with a touch of a finger (the flight path is drawn with one touch). After specifying the trajectory, a point will appear, which will independently begin to move strictly along the drawn line. The drone will duplicate the movements of this point.
5. As soon as the quadcopter starts flying along the route, the video image from the drone camera will be displayed in real time.
6. At the end of the flight, the X5UW-D will hover in position hold mode, waiting for the next commands.

Recommendations

If the aircraft pulls sharply to the side during takeoff, the compass must be calibrated. It is recommended to perform pre-flight calibration on a horizontal surface.

Calibration process:

1. Turn on the aircraft
2. Place the aircraft on a horizontal surface
3. Turn on the remote control
4. Bring both sticks to lower right position
5. Wait for the backlight to change from flashing to solid. Calibration complete.
6. If necessary, achieve accurate position hold by adjusting the offset (trim) from the remote control.

Price

Syma X5UW-D is sold by the developer through all well-known trading platforms at an average price of $ 60.

Pluses

• Design
• Wear-resistant materials of execution
• Flight properties
• Touch positioning / Altitude hold
• Flight along a drawn route
• HD camera (image quality)
• FPV
• Headless Mode
• Motor Blocking Control (Safe)
• Charge Control (auto-landing with insufficient battery charge)

Disadvantages

• The correctness of the “Flight along a given route” function directly depends on the quality of the Wi-Fi connection
• The quality of the video stream (long delay time when moving further than 15 meters)
• Noisy (reducers)

One of the best offers in the occupied niche UAV. The modified model turned out to be more indicative of its predecessor and is now ideal for getting the first experience in management and adaptation to piloting in first person mode. Separately, we can highlight the control of blocking of motors, as well as a soft landing with a low battery charge, for beginners, extra safety will not hurt. Age limit 12.
