The Phantom 3 Professional Quadcopter 4K UHD Video Camera Drone is another improvement that has been added to the DJIs Phantom series. With a fully stabilized 3-axis 4K UHD video camera this drone is surely a masterpiece when it comes to taking high-resolution videos and quality photos. The 4K UHD video camera drone can be purchased at a highly competitive price of $1127.00 (Quadcopter only). With an additional battery you can also get it at the cost of $1259.00. A few other accessories that make it worthwhile include 4k UHD video camera with fully stabilized 3-axis gimbal. The inclusion of Lightbridge digital streaming makes viewing of 720p video possible. Flight battery and rechargeable remote controller make the machine fully set to fly. The drone has also been fitted with DJI Pilot app for iOS and Android for possible live viewing and total camera management. This product is restricted to flying within 15 miles radius of the White House.
If you have ever wondered what you need to get started in the RC hobby of multirotors this is the place for you. In this article I am going to outline all the basic components that are necessary to get started building your own quadcopter. First you are going to need a transmitter. The transmitter is the radio control that you use to communicate with your unmanned aerial vehicle (UAV). There are various types of transmitter that are categorized by brand frequency and number of channels. For a quadcopter you need at least a 4 channel transmitter but I would suggest getting a 6 channel transmitter that works on the 2.4GHz frequency.
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.
