A review of a fairly successful and relatively inexpensive quadcopter from Skytech, which boasts the ability to fold, automatic altitude hold and control, both using the complete control panel and using a smartphone / tablet. A fresh “trick” in the world of quadcopters today is the ability to fold/unfold the arms of the engines, which allows you to significantly (up to 2 or more times) reduce the space required for storing the quadcopter, as well as protect the device from damage during its transportation.
The Chinese company Skytech has released its next novelty under the index TK110HW, in which such an opportunity was successfully implemented.
The technical characteristics of the quadric are as follows:
- Engine type: collector
- Radio control: 4‑channel
- Stabilization: 6‑axis
- Camera resolution: 0.3MP
- Remote control range: up to 50 m
- Smartphone control range: up to 30 m
- Battery: 3.7V 850mAh Lipo
- Charging time: about 110 min.
- Flight time: 8–14 minutes (depending on load)
- Weight without battery: 390 gr.
- Unfolded size: 360x360x85 mm
- Controlled by remote control or smartphone/tablet
- Double costs, acrobatic somersaults (flips)
- FPV over WiFi
- Auto return
- Headless Mode
- Smartphone tilt control function (gravity sensor)
- Automatic takeoff and automatic landing with one button
- Dedicated barometric sensor for automatic altitude hold
- Flight along a given trajectory
The quadrocopter is delivered in a good, dense, two-layer package.
In addition to the device itself, the package includes:
- detachable 0.3MP camera;
- 3.7V 850mAh LiPo battery;
- USB charger;
- spare blades (4 pcs.);
- blade protection (4 pcs.);
- smartphone clip;
- instruction in English.
The regular control panel is supplied with the information monochrome LCD display.
The remote control is powered by four AA batteries / accumulators.
On the front end of the remote control there is a flip button (somersault) and a button to turn off the “dual costs” mode. Also, in the upper part there are separate buttons for turning on the Headless mode and the automatic takeoff / landing mode.
To free the quadric from the box, I had to tinker a bit. The yellow stripe on the hull is a warning about how to correctly lay out the beams with the engines so as not to damage them out of ignorance.
When folded, the copter fits easily in the palm of your hand.
The motor gearboxes are covered with transparent overlays, under which there are also backlight LEDs (green — at the back, red — at the front).
Near each beam there is a small chrome button, which is a lock of the unfolding mechanism.
If you need to fold/unfold any of the beams, this button must be kept pressed.
This is what the copter looks like unfolded.
However, he no longer seems quite a toy.
At the bottom there is a 0.3MP video camera unit with 2.4GHz video transmission (via WiFi) and a battery compartment.
The angle of the camera can be adjusted vertically.
The camera unit itself is removable, integrating the WiFi module. If there is no need to shoot, you can remove it and add a couple more minutes to the flight time of the copter by reducing weight.
The battery compartment is designed without any margin in size, so I had to rack my brains a little to find a position in which it could be closed with the connector connected.
To charge the battery, you must use the bundled cable with a USB connector, which can be connected both to a computer and to any charger with an appropriate USB socket.
To turn it on, you need to press and hold the button on the back of the copter for a while until it starts flashing LEDs and then turn on the remote control for synchronization.
It is very convenient to use automatic mode for takeoff and landing. Just press the button and the copter takes off on its own to a height of about 1.5 meters from the surface.
Pressing again — the device lowers itself and turns off the engines.
The automatic altitude hold function does not require any activation, simply by reaching the desired altitude, you can release the stick and the aircraft will hold it on its own.
All control functions can be used without a standard remote control, controlling the copter using a smartphone or tablet via WiFi. To do this, you need to download the special WiFi GO application, install the camera unit and turn on the copter. After that, in the list of available networks, find the one created by the copter called SKY_WIFI_, connect to it and launch the application.
The screen will display the controls of the copter, as well as the image from the camera itself.
In a special mode on the screen, you can draw a trajectory along which the copter will fly. True, this must be done either in a very large room or on the street, because. there should be plenty of room to maneuver.
In addition, the program can be switched to control mode using the tilt sensor of the smartphone. After that, the copter will be controlled by tilting the device in the desired direction. These control modes can be seen in the video at the end of the review.
As it turned out, the copter is very easy to operate and even a novice “pilot” can handle it. A big role in this is played by the ability to automatically hold the height, in which you do not need to worry that as a result of a rash or too abrupt change in the position of the control stick, the copter will fall or hit the ceiling.
If desired, in complete calm, of course, you can even remove your fingers from the controls and watch how the copter imposingly barrages in the air “by itself”.
In general, the quad turned out to be very successful, its main drawback is only video shooting, which, firstly, can only be performed on a smartphone, because. The quadcopter does not have a slot for a memory card, and secondly, the quality of this very shooting is rather mediocre. But in this case, it is necessary to recall the small cost of the copter, which could not have been so if the developers had installed a good, expensive camera in it, as in a bearded joke about a taxi — “Do you want checkers or go?”.
