For the RC helicopter beginner, something you must listen

Nowadays, more and more people start to fancy RC models and if you have become one of the “RC club” members, then welcome to our world! This article is written by a professional experienced player. Here are something he wants to tell all the RC helicopter entry player.

No matter which helicopter you choose, I think the following three points are very important:

1.Before using the helicopter, you have to have a full psychological preparation. RC Helicopter is like the remote control car which will not be too dangerous. The RC helicopter is not the same, learning to hover and keeping balance is not easy. Control the helicopter to keep the correction of the body, or dangerous accidents might happen.

2.Be sure to buy a simulator at the same time. Use the simulator for training is very necessary. Only when you have the formation of the correct conditioned reflex so that you can play well in order to ensure fewer crashes or no crashes.

3.Do not start to play the difficult moves, fly "3D" and so on. This is absolutely wrong. RC Helicopter from the entry to the 3D flight needs to go through a lot of practice.

After the purchase of a helicopter, here are some necessary prepare works:

1. parcel check.

After opening, remember to check whether the appearance is good, random accessories are complete and so on. There will usually be a manual, which has a packing list, according to the list written, you can check all the accessories lists. Special attention is that some small things, such as the small hex wrench, inserted in the bubble inside, it is easy to be ignored.

2. charge.

Usually, charge 1.5-2 hours, do not overcharge. The charger has a two-color indicator, the general red is charging, green means finished, the charger will automatically stop.

3. the initial debugging.

This debugging has a lot of steps, the tools needed is very simple, is a small Phillips screwdriver, very easy to use.

4. spare parts.

If you love to have some DIY work such as modification and refitting, you need the plastic gear set which is for all kinds of DIY cars, robots, model making accessories. The gear spare parts package is suitable for the DIY model including 80 kinds of gear parts. It can meet all your DIY needs, and super affordable.

The highest cost performance drone brand - WLtoys review

WLtoys Q333A - 7.8/10

We have said that in the consumer-based aerials, only DJI Inspire 1 and Yuneec Typhoon H are currently equipped with automatic retractable landing gear. Unexpectedly, WLtoys Q333A also has the same function, but it is even cheaper. This is an unbelievably good news to many players as this allows the RC players to try transforming flight forms experience in the air at a lower price.

Wltoys Q333A provides three flight modes: by raising the shaft and four-axis propeller, while the body to sink so that it will transform into the different body shape. Wltoys Q333A has a modified flight form function, coupled with its stable flight performance and its photography images can also reach the high-definition level, so it sounds more attractive. It is worth mentioning that the same series Q333B and Q333C version, mainly to switch to Wi-Fi map and delete the map transmission function in exchange for a cheaper price.

WLtoys XK X300 - 8.7/10

In order to facilitate entry-level players, in recent years, many low-cost aircraft are introduced "one key taking off", "one key landing" or automatically setting height and other functions. But WLtoys XK X300 is further, adding Optical Flow Positioning technology so that the aircraft can be stably stuck in any designated location.

WLtoys XK X300 price is not expensive, but has the built-in barometer and optical flow sensor, and also provides one key to take off, one key landing, automatic height setting, automatic positioning and other automated flight functions, plus its control and aerial photography performance is also satisfied. So it can be said one of the most cost-effective products in the market now.

Except for these two model types, there are many other star drone types of the brand WLtoys we will review in the future such as the popular WLtoys V922, WLtoys Q393, WLtoys Q353, WLtoys V686 and so on. If you have bought a WLtoys drone and are looking for some spare parts, here are some cheap grommets for you.

Should we let our children learn musical instruments

The necessity to learn musical instruments

In fact, learning musical instruments is a comprehensive training and a good way of development of young children. In addition to cultivating music talent, it will also cultivate sentiment enhancing the ability to appreciate art. Pre-school age is the best time for learning music in a lifetime. The effect will be much better than later because in this period, children's fingers, joints are developing, so they have more flexible fingers and learn musical instruments easier. To develop your children all-around, some cheap education toys are also needed.

The age to learn musical instruments

Sooner the better? No.

Take the piano as an example. When children playing the piano, their hands and feet are used together, eyes to see, ears to listen and the brains to think, so the ability to coordinate will be improved greatly. The children of good coordinate ability can learn new knowledge and memorize knowledge better in the future significantly than other children. But I do not advocate children younger than 3 years old to learn piano too early as their hands are too small without enough strength, and they do not understand the music theory spoken by the teachers. The most suitable starting age should be 3-6 years old.

Orchestral instruments should generally begin after the age of ten. Vocal music should start the formal training be after the voice changing period (usually fifteen or sixteen years old), but the general singing can be learned from childhood.

Before starting, do some preparation

Except for communications with your children about their interest and willing, I think, the parents should also do some preparation mentally and financially as once your child has started to learn a musical instrument, it’s not recommended to give it up too easily. If you can afford to purchase a musical instrument for your child, you also need to concern about the classes fee which is also quite expensive.

For those children who want to learn guitar, I will recommend the guitar plectrum holder which is durable but affordable and I will also offer some cheap guitar kit for you to choose so that you don’t need to spend a lot.

Quadcopter might be the hottest now, but do you know its principle?

For a new technological invention, people are always used to blindly follow instead of trying to know and understand. The quadcopter, or can be called as the drone, is no exception. Happily, with the quadcopter cost reduction, a considerable number of people began to actually use quadcopter and applied it to travel, live, entertainment, photography, disaster news reports, and other scenes. This time, the quadcopter can be said to be officially entered the consumer area. Rhett Allain, a professor of physics at the University of Louisiana, shared some of the physical principles of drone in the article "How Do Drones Fly Physics, of Course!", So that we can better understand its principle. This is very necessary for the beginner who doesn’t know the drone quite well but ready to buy one.

Besides, you might also need to know some quadcopter spare parts such as the 3.7v battery or the 7.4v volt lithium battery and the charger.

Vertical movement

The quadcopter use rotor to achieve movement. The relativity of force means that when the rotor drives the air, the air will reverse the rotor. This is the basic principles of the quadcopter being able to vertical move up and down. Further, the faster the rotation of the rotor, the higher the lift, and vice versa.

Three basics

Today's quadcopter can do three things: hover, rise, and fall. When hovering, four rotor’s thrust is equal to the downward gravity. This is very easy to understand. So how about rising? Increase the thrust of the four rotors to produce an upward force which should be greater than the gravity. So when falling, on the contrary, just reduce the rotor thrust speed.

Rotate

How to make a flying north quadcopter to turn south? What is the principle of the movement of the rotor at this time?

When the two sets of rotors are rotating in the opposite direction, the total power of the quadcopter is zero. So it can achieve hover. If you want to turn right, you need to reduce the angular velocity of a group of rotors. However, although the lack of thrust from the rotor 1 can make the quadcopter to change the direction of movement, at the same time the upward force is not equal to the downward gravity, so it will decline.

So another question is - how to keep the quadcopter change the direction but still in the same height level?

While reducing the rotation speed of a group 1 rotors, at the same time, increase the rotation speed of another group of rotors. At this point, the angular force of the rotor is still not zero, so the quadcopter can rotate. While the total force is still equal to the gravity, so it can be kept at the same height. Turning left is also the same.

By explaining the principle as easy to understand as possible, I hope this article will be practical for you. At the end, I also want to recommend the Syma quadcopter for you which is a good choice for drone beginner.
