We are already preparing to fulfill the New Year’s wishes for children. Our kid made a wish with Santa Claus an airplane on the control panel. The husband, as usual, complicates everything, and instead of buying a toy according to the age of a five-year-old kid, he would rather buy one that he himself would not mind playing with. So, we ordered a non-toy drone, a high-speed Predator Z51 with a fad for ages 14+.
What is interesting about this model? Simple, but aeromodelling, practical materials and hull design, significant dimensions, easy control (according to age), the presence of a gyroscope, range and flight time.

Packaging, delivery set and appearance description
In front of me is a Predator Z51 aircraft. The packaging is a large cardboard box with a carrying handle. Gross weight 560 grams. The box shows the model, main technical capabilities, image of the device and operating conditions.




The package included:
- Aircraft (components)
- Battery
- USB charging cable
- Plastic wing retainer
- Screwdriver
- 3 bolts
- 2 spare propellers
- Remote control
- User’s manual
The aircraft was packed securely, and this is not surprising, because the aircraft itself is made of foam. This is a prefabricated model, therefore, a set of parts that are placed in a foam backing.






This toy model copied the original well: everything is in order with disguise in terms of color, the wingspan, as expected, is almost 2 times the body length, the tail is V‑shaped. from a copy, there are 2 engines and they are on the wings.
About the gray body — this is not good in cloudy weather at a great distance, it is easy to lose it. The wingspan is good, and the plane holds its balance well when landing. But about the tail — there is a flaw here, in a real predator it is made in the form of an inverted letter V. I was not mistaken, there is only one way to install the tail, as in the photo.










The case consists of combined materials, mainly — it is a strong foam. There are some plastic inserts.
Body length 40 cm, at the widest point 5.5 cm. Wing length 33 cm.








The wings are marked L / R, 2 screws, one on each, from which thin wires stretched. the plane was assembled within 5 minutes without instructions, but it is included in the kit. Instruction in English and Chinese. You will not need any special tools or glue to assemble the airplane. The only thing, maybe for the first flight you will have to recharge the battery. And yet, the first launch will be canceled if you do not have 4 AA batteries for the remote control at hand.








The chassis is attached to the body, the tires of which have pads made of soft material. The chassis is well cushioned by a thin spring-loaded wire.


Remote control
It is a large square case with beveled corners made of matte black plastic. The plastic is strong. The case does not creak when pressed. The control panel is represented by 2 joysticks, the left one moves up/down, the right one moves left/right. Under the joysticks there are 2 buttons, the right one is a trimmer, the left one is a model. The on / off switch is located in the center, it works softly with a click. There is also an indicator of the operation of the device. On the front end there is a carrying handle, a 2.4 GHz antenna and 2 side buttons, the right one is responsible for the backlight (but it is not provided in this model), the left one is the speed controller.
On the opposite end there are legs for setting the remote control in a vertical position, in the central part of the case there is a strap mount. On the back side there is a slot for 4xAA batteries.
In work
Before proceeding with the description of flights, a few words about installation — the device is mounted quite easily, no special instructions for its assembly are required, it is enough to install and connect the board, battery, attach the landing gear, fix the tail section and activate the control path by supplying it with 4 batteries of the type AA.
The aircraft is controlled only by the remote control, no special mobile applications are required. Here it is necessary to describe the operation of the PU buttons. Let the large number of buttons on the remote control not confuse you, some of them are fake. The left joystick acts as a gas pedal and has a forward / backward stroke. The right joystick allows you to steer the aircraft left/right.


In order for the airplane to take off, you should start it with the power button located on its body and turn on the remote control. This establishes a connection between devices. This aircraft does not need a runway for acceleration, it can take off by hand. In this way, launch the aircraft horizontally into the wind, only a small angle of inclination up to 15 degrees is allowed. For a normal drone flight, weather conditions should also be taken into account. The manufacturer says about them in the instructions, the case does not have moisture protection, and to start you should choose a calm day without precipitation. Wind speed should not exceed 4 m/s. Of course, we did not wait for such weather and tested the aircraft in harsh conditions for it.






The range of the remote control is no more than 150 meters, then the aircraft loses contact with the control source and crashes. If you need to urgently interrupt the flight, just turn off the power button on the control panel, the propellers will continue to work for another 3 seconds, then they will stop and the plane will crash.
It is worth saying that in those descriptions, the manufacturer also warns about the maximum weight load. Thus, the manufacturer allows the installation of additional modules, such as a backlight or a small camera (not included).
To land the plane, you need to slow down and bring it as close as possible to a flat surface. For a soft landing, the design provides for wide wings and spring-loaded landing gear with soft wheels. In order not to lose them during planting, I would advise you to take them for glue.
This aircraft model is equipped with a stabilization system, due to the gyroscope, and also has feedback from the remote control to signal the battery discharge.
The battery life of the drone is 15 minutes. The battery is charged within an hour. The USB cable is used to charge the battery. To extend the flight time, you can buy a spare battery, but you will need a screwdriver to remove it.

Conclusion
So, our drone after the first flight remained without damage!!!
At the moment, this was the only launch, because. the plane will be given to the child. The weather turned out to be non-flying, and our flying object was intractable. During a strong wind, it was not possible to launch it out of hand, although I watched a video where this model is easily launched in this way. There were hard landings and an accidental fall into trees (during the flight, the gas pedal was completely released). In the trees next to the “predator” (predator) sat a huge plump hare! and then how it will run … From surprise, I was confused and did not have time to photograph either the attack of the predator or the handsome hare.
The plane is quite frisky, but responsive. An adult will like to control it, and the flight is much more interesting than the flight of a quadrocopter. But I don’t dare to say that a child of 5 years old will cope with his control.
What I want to say about the quality of materials and reliability, of course, at first glance, the foam body will seem unreliable, but practice has shown that foam products are ideal for flight and soft landing. This material is not in vain used in the manufacture of toy flying machines, this makes them light and cheap. From experience: even after an unsuccessful landing, it is like new: the case is intact, the screws and removable parts are in place, there are no visible signs of use.
Conclusion: Predator is a great drone and lives up to its name!
