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.
There are a lot of quadcopters out there for beginners. The Smya X1 is one of the most popular. I like it because it has a 2.4GHz transmitter is very durable and very easy to fly. You can also make it do flips at the touch of a button to impress your friends. But recently I just got the Blade mQX and I must say I am quite impressed. It is actually similar in size to the Syma X1 but it boasts better performance with 4 brushed 8.5 mm motors 5.5 inch blades and a 4-in-1 receiver/ESCs/mixer/sensor that acts as flight control board. The built in DSM2 receiver is one thing I really like about the Blade mQX a lot of quadcopters come with proprietary transmitters and receivers and it can be difficult without hacking the hardware to make it compatible with your existing transmitter. With the Blade mQX you are able to bind it with any DSM2 compatible radio such as Spektrum radios.
The main function that makes these UAVs different from the ones available off-the-shelf is their ability to fly autonomously. This means that the vehicle is able to make decisions depending on its flight to change direction capture images or return to ground. These machines come equipped with various sensors and in order to make a decision the input from different sensors is merged. They are also able to communicate with other UAVs flying around as well as with ground stations and satellites. They are capable of determining the ideal course for achieving a mission. These powerful capabilities make them extremely sensitive and sophisticated devices and these operations are not available in quadcopters used for the purpose of fun and entertainment.
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.
