RC Quadcopter

An RC Quadcopter is one of the latest versions of the RC helicopter to hit the market. There is a lot of difference between the traditional form of RC Helicopter and an RC Quadcopter, and not just in terms of the number of rotors on it. There is a massive difference in the way each model is setup and, therefore, in the way the model functions. This means that in certain aspects, it is better to own an RC Quadcopter but in other terms, you would be much better off with a regular RC helicopter.

To know whether you are built for an RC Quadcopter or whether you should stick to a regular RC helicopter, you need to understand how they work, the principles behind their overall functioning and everything else that goes into making an RC Quadcopter & helicopter and getting it up in the air. look at, Dinky Diecast

The Working Principles of an RC Quadcopter

To begin with, the structural difference of an RC Quadcopter will become the most important aspect you will need to pay attention to. Unlike a normal helicopter that has two rotors, an RC Quadcopter has four rotors, which account for the thrust, balance and pitch. In a regular helicopter, the main rotor is used for thrust while the tail have a look at, Cape Malay recipe for tomato soup rotor is used for balance and pitch. The main role of the hobbyist is to control the function of the tail-rotor, when they do when they change why not visit, RC Tank Combating direction or altitude, and then use the main rotor's constant (or changeable) speed to move the helicopter ahead.

In the case of an RC Quadcopter, the process is a lot more complicated. Basically, amongst the four-rotors that you have, a pair of opposing-rotors rotates in the same direction (say, clockwise) while the other pair rotates in the opposite direction (anti-clockwise). These opposing sets of torque maintain the balance of the RC Quadcopter and ensure that it stays stationary in air. also see, Tamiya RC Cars

Then comes the bit about moving it around and even though you are effectively turning the joystick, on your remote, to right, left, up or down, what you will be doing is increasing or decreasing the speed at which one or more of these rotors rotate. You may manipulate the speed of multiple rotors at one time or just one, depending on what you are trying to make your RC Quadcopter do. Every single rotor blade in an RC Quadcopter is symmetrical, ensuring that an action on one has a similar effect on another, either in the same or opposing way.

Controlling an RC Quadcopter

Every rotor blade of an RC Quadcopter is produces two types of forces - thrust and torque. There is also a third force, the drag, which goes against the direction of flight and this is where aerodynamics comes in - the more aerodynamic a flying object, the lesser the drag. Assuming the four rotors are numbered 1 through 4, then number 1 and 3 (say, clockwise) usually rotate in the same direction while 2 and 4 are in the opposite direction (anti-clockwise). The net acceleration in every direction remains zero, therefore keeping the RC Quadcopter stable.

If you want to move the RC Quadcopter in a particular direction, then you need to rotors that are spinning in one direction. So, you will either apply greater thrust to the clockwise-spinning rotors or to the anti-clockwise ones. This will make the RC Quadcopter move forward or sideways. Again, if you want the RC Quadcopter to spin on its central axis, then you will apply more thrust to just one of the four rotors. Now, this is just the principal of how an RC Quadcopter flies and when you are holding your radio controller, you won't have to worry about these details. You will just be pulling the joystick to the right, left front, back, up or down and the control surfaces on your model will do the needful adjustments to its rotor speeds for you.

Enjoying your RC Quadcopter

The thing about an RC Quadcopter is that it looks more like a UFO rather than a conventional helicopter. RC enthusiasts say that if you want to learn flying, experience with an RC helicopter will definitely boost your chances of flying an RC Quadcopter better. That said, these models are used extensively in research by numerous organizations and universities who are looking into the science behind flight control, navigation techniques and even, to a large extent, robotics.

They are a very versatile and controlled way of flying, though a bit more complex in mechanical functionality, but a lot simpler to control for a hobbyist. They are also ideal for mounting things like cameras consider, Chocolate Sandwich Cake and getting an aerial view of places, also look at, DIY Shower Doors although we wouldn't recommend peeking into your neighbours' homes have a look at, RC Fighter Robots using these flying machines.

All-in-all, if you are a fan of flying RC helicopters then you will really love an RC Quadcopter. They are quick, agile and extremely easy to manoeuvre and also give you the ability to mount cameras consider, Knotted Weaving & recording devices on them to capture an aerial view of the surrounding area. There, probably, isn't any other RC model that gives you as many options as the RC Quadcopter does!
