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.
When you take delivery of your first Quadcopter see to it you also look for a Flying Quadcopters Drones and UAVs Tip sheet. Suggestion sheets will enable you to fly your craft securely and confidently. You will also find directions on how you can set up your model. We also strongly advise that you read the manual a number of times so you become familar with the functionality of your model and the remote control transmitter. When learning to fly always fly slow and fly low to start with and never fly in close proximity to people. However small your craft is the propellers spin at a very high speed and can cause injury. If flying outdoors make sure you keep the sun behind you and fly at eye level. Many of the Micro and Nano Quadcopter can perform acrobatics but dont try these tricks until you are totally in control of your model and have perfected the basic flying skills.
You may have seen some pretty amazing flying vehicles these days. UAVs (unmanned aerial vehicles) are becoming more and more common. The hobby is also getting more and more easy to get into. But with the great range of models and brands you may wonder what is the best quadcopter to start out with. There are a several variations of the multirotor family. The most common is the quadcopter like the DJI Phantom. A quadcopter uses four motors and propellers to generate the thrust necessary to lift the aircraft. It can be more mechanically simple than a traditional helicopter that requires a tail rotor to counteract the angular torque produced by the main rotor and the main rotor does not require collective pitch and other mechanical complexities. With a quadcopter the pitch is fixed and the flight control is achieved by actively changing the motor RPM (revolutions per second).
Next I needed to decide what the frame was going to look like. The size of the motors was determined by the size of the frame and the payload. In other words the size of the camera I wanted to use was a key factor to how strong the quad needed to be. What material to use for the frame? Carbon? Aluminum? Fiberglass? We always want to use the best at first but reality soon sets in. I watched the video of another quadcopter made out of wood that flew beautifully. Wood was inexpensive and strong enough to meet my needs and it only cost about $5! There are many ways to build the frame. It would take far too long to describe all the decisions I had to make. We need to get to the flying! In the end I decided that designing my own custom frame was the way to go. I wanted to be really proud of my quad.
