So in a quadcopter each of the motors are configured such that they cancel one of the others out. So when you want to yaw (turn right or left) then two motors across from each other diagonally will reduce their speed and the other two across from each other will increase theirs. This maintains the lift necessary to maintain altitude but imparts angular torque to the aircraft which makes it turn. Now it would be impossible for a human to calculate exactly how much change in RPM to impart to a quadctopers individual motors to maintain control so these calculations are carried out by a flight control board. This board is usually equipped with pyrometers and sometimes accelerometers. It has software that controls the motors based on the position of the aircraft and user inputs from the transmitter.
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.
They appeal to all everybody and all ages too! Quadcopters are a huge amount of fun and they arent just for boys either! Girls also love being "pilots" and enjoying the thrill of commanding their drone either just around the skies or performing intricate stunts and manoeuvres. And these bad boys of the sky arent just for kids either. From as young as 7 years old right up to grandparents there is a drone or quadcopter that will suit. There is an absolutely HUGE range of quadcopters for sale that will cater to any budget and also please the most demanding of "pilots." From a small entry level quadcopter that can fit into the palm of your hand right up to an incredibly advanced... and expensive version that costs more than the average family car! Want four propellers? No problem? How about an eight propeller octocopter? Too easy! Want a protective circular cage around your drone or maybe perhaps even in the shape of a fighter jet? There are so many different options available to you! Just go down to your favorite RC store choose what you want and you are ready to go!
Now then for the outer assembly - more safety is garnered by outer bearings but reduced friction is the key thus electromagnetic system makes sense but due to weight perhaps not 100% magnetic. This article explains the concept of Thrust Bearings and the combinations I propose we employ. "Design Fabrication and Performance of Foil Gas Thrust Bearings for Microturbomachinery Applications" by Brian Dykas Robert Bruckner Christopher DellaCorte Brian Edmonds and Joseph Prahl. (NASA/TM-2008-215062 January 2008; GT2008-50377). Currently we know that the quadcopter design is probably one of the most stable designs yet but most quadcopters are only toys small drones and have a limited payload. If we want these types of designs to fly around people heavy weight or become our future flying cars and air taxis commuter shuttles well need near 100% safety that means current rotorcraft components may not be viable. Please think about the future maybe you can have a flying car after all?
