So that may all sound pretty complicated but dont be scared because all that complicated stuff is handled in the flight control board. All you have to worry about it moving two sticks one way or another. So which quadcopter will help you get off the ground quickest? One of my all time favorite quadcopters for beginners is the Syma X1. It is very inexpensive and flies very well. It comes with a 2.4 GHz transmitter so you are able to fly outdoors and get pretty good range. Another good beginner quadcopter is the Blade mQX. This is a great little quadcopter as well and one nice thing is that it is compatible with other radios so you dont have to rely on the one it came with. Both are durable and will provide you with hours of fun flying time.
If you want to move forward the back two motors spin faster and the front two motors spin slower. This tilts the aircraft forward and vectors the thrust in that direction. If you want to roll then the same principle applies but on the lateral sides. If you want to yaw then you must understand angular torque. A spinning object will produce torque proportional to the speed with which it is spinning. That is why on traditional helicopters you see a main rotor and a tail rotor. If the main rotor is spinning counter clockwise the entire aircraft will want to spin clockwise to conserve angular momentum. That is why the tail rotor is necessary it produces the necessary thrust to counteract the forces of the angular momentum.
Fourth you will need a battery to power all the electronics. Lithium Polymer (LiPo) batteries are the most popular batteries for the RC hobby. LiPo batteries are characterized by their number of cells (voltage) and capacity (mAh). Each LiPo cell has 3.7V so a 1S (1 cell) battery will be 3.7V a 2S battery will be 7.4V 3S 11.1 V and so forth. Capacity is rated in milliamp hours (mAh). The higher the number of mAh the longer the battery can power the quadcopter. Lastly you will need a frame to put all this onto. There are many commercially available quadcopter frames. Some are in the + configuration which means one of the arms acts as the "forward" orientation. Some are in the X configuration which means that "forward" is between two of the arms. There is also the H frame where forward is on the flat side of the H. H frame is great for FPV and aerial photography since the rotors are out of the way.
A remote controller or transmitter allows the pilot to control the quadcopter and change its settings according to your skill level. This device needs batteries to operate. Propellers spin and make the it take off; the faster these spin the faster it moves. A quadcopter consists of four propellers. A camera is an optional part for many quadcopters that are designed just for fun. However if your copter comes with a camera you should be very careful in its handling because a lot of collision and failed landing attempts might break the camera lens and render it useless. There are four controls that allow a person to maneuver a quadcopter in air. There are known as roll pitch yaw and throttle. Roll and pitch make the machine move left or right and forwards or backwards respectively. As it is clear from the name roll makes the quadcopter roll. Yaw on the other hand means rotating the machine left or right. Throttle is used to adjust the altitude of the vehicle in air. You can move it either backwards or forwards.
