Every boy has a racing dream, and it ’s like a boy ’s nature to like cars. My nephew is familiar with various car logos at the age of 5 years old, and of course remote control racing is also essential. I have also played many remote control cars, but the savage doll P-201 remote control sports car I experienced today is really a bit different. What’s the difference? Tookfun will come to experience it today.
Exterior
After opening the package, there is not much inside. Remote control sports car, remote control and manual.
The remote-controlled sports car is a classic streamlined shape. The small sports car uses 5 type wheel hubs, flat TPR soft rubber tires have better grip and wear resistance, and can be applied to all kinds of roads. The black intake grille of catfish mouth style is domineering. The cockpit of the aircraft cabin has a high-tech feel. The white stripes and numbers on the blue car body also add to the taste of the racing car. This styling design is said to have won the German Red Dot Design Award. I believe everyone who sees it will like it very much.
The size of the remote control sports car is 174mm * 84mm * 52mm, which is slightly petite compared to this big off-road vehicle.
The remote control sports car has suspension systems at the front and rear wheels. The left and right front wheels are independent spring suspensions, and the two rear wheels are integrated spring suspensions. Has a certain performance of overcoming obstacles, and at the same time improves the handling feel. After taking a closer look at the front and rear bars, it was found that it was not just mellow and full. The chassis is designed to highlight the details of the car body, and it can also be understood as the front and rear lips, which increases the safety of the vehicle during a collision and increases the rigidity of the car body.
The bottom of the body is the switch and battery compartment. The chassis of the sports car is relatively flat. The front wheel adapts to the maximum steering angle. The presence of the differential wheel can be seen at a glance at the rear wheel, which greatly improves the steering maneuverability. The power switch is designed in the middle position, and the car can only be remotely controlled normally after the remote control and body power are all turned on.
Let’s take a look at the remote control again. The same is the classic control mode of the front and back keys plus the left and right keys. The savage doll is different from other racing cars in the front wheel fine-tuning keys on the remote control. When you find that the car does not go straight, you can use this button to make instant adjustments.
Savage doll need 4 batteries for No. 7 batteries, while the remote control requires 2 batteries for No. 7 batteries. Unfortunately, this remote control sports car does not come with a battery, but we also have to buy the battery separately.
Practical
As soon as the power was turned on, the savage doll started a drag racing show. The control of the remote control is sensitive, and the remote control distance is also very far.
It is difficult for other remote control cars to do drifting movements, but the savage doll are very easy to do it.
Through the rotation speed of the front wheel, you can see how fast the savage doll responds to the remote control.
Come to a large drift. Why is it called “savage doll”? It is because this remote control car has two modes! In addition to the normal mode, you can also enter the brutal mode (push the throttle to the maximum, and then open the switch to enter). First of all, it can be distinguished from the sound. The barbaric mode really brings the roar of the sports car’s engine; the second is the increase in speed. It may feel great to use for competition. And the remote controller of other remote control cars may have string frequency phenomenon. The barbaric doll remote control sports car is equipped with a 2.4G remote control system. One remote control can accurately match one car, and multiple cars are not afraid of competition.
Let’s take a look at the fine-tuning, which is instant feedback.
The savage doll is equipped with a micro differential. The speed can be significantly increased from slow to fast.
Tear down
According to the official introduction, the reason why this remote control car is different from the ordinary remote control car is that it uses a fully digital hollow cup steering gear. Very curious about this, so I decided to take the car apart and study it.
Remove all the screws at the bottom. Note that the battery compartment also hides two screws. The car shell is relatively easy to separate from the body. We can also see the rear wheel shock absorber of the remote control car. The rear wheel motor also has a gearbox assembly structure. The motor is an ordinary motor, which is only connected to the power line and the control circuit.
The digital hollow cup steering gear and the control circuit board are fixed by two plastic covers. Remove the 6 screws above, you can see the steering gear and the control circuit board.
There are two chips on the front of the control circuit board. A STM32F030Kbt6, this is an ARM Cortex_M0 core single-chip microcomputer (32-bit, Flash32K, RAM4K) of STMicroelectronics, it is OK for toy cars. Another one is A7137, check the information, it is 2.4G RF transceiver chip. The main control chip controls it to communicate with the remote control through the SPI serial port. The main device on the back is two NCE4606 MOS tubes, and the main control chip is to control the driving current of the MOS tube through PWM mode, and then control the speed of the remote control car.
Now look at the digital hollow cup steering gear. Through the transparent plastic, you can see the internal structure. The visual inspection consists of a stepper motor and several gears. The motor drives the front swing arm by driving the gear set, which in turn controls the steering angle of the front wheels.
Conclusion
Advantage
- Compared with infrared control devices, devices controlled by Bluetooth can achieve more complex scene operations. Such as remote control.
- The exterior design adopts retro design, which is obviously different from other remote control cars, and has a sense of design and distinction.
- The use of thickened shell and shock absorption design is indeed more suitable for outdoor complex and changeable situations. The collision occurred many times during use, and the body did not leave scars.
- The racing car has excellent acceleration performance and can even feel the grip.
- The grip of the remote control is very good. It fits perfectly with the hand shape and is very small in the hand.
Deficiencies
- The battery compartment is where I think the design is insufficient. One is to choose the 7th battery instead of the 5th, and sacrificed battery life in pursuit of the compact body shape; second, the battery compartment design of the remote control is more disappointing. The battery is easy to put in but difficult to remove.
- The front wheel fine-tuning button, the actual control effect is not big. The design of the wheel joint is not too tight, which makes the wheel easy to shake, so this car is difficult to take a straight line, and it needs to be adjusted at all times.
- There is no protection between the chassis and the car shell. This is likely to cause dust and foreign objects to enter the interior of the car easily when used outdoors, which is not easy to clean.
Overall, as a remote control car for less than $ 40, the Savage doll Remote Control Sports Car P201 has safety, reliability and playability. The overall design is excellent, the shape is cute and pleasing, and the addition of the differential of the rear wheel of the digital hollow cup steering gear improves the overall control level. Switch between two modes, play whatever you want. The heavy feel, solid materials, not easy to break. The rounded shape will not cause too much accidental damage to young children. As a children’s toy car, it is still highly recommended.
