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.
If you are thinking about getting into the RC hobby then you have most likely seen the quadcopter craze that has swept the world. These little unmanned aerial vehicles are very fun to fly you can hover you can go backwards you can go straight up or down. All things that you cant really do in an RC plane. But it is also a little bit more difficult to learn to fly (I think). The reason for this is because of orientation. With a plane it is much more clear which way is forward and to maintain lift you are always going forward. However with a quadcopter or any multirotor it is much more difficult to maintain orientation because you have a symmetric frame. If it is a quadcopter you have 4 motors in an X formation and you can choose which way is forward by how you mount the flight control board. But once you get up in the air you have to remember which way is forward and maintain that orientation through all the maneuvers. I have found that a good way to help maintain orientation is by making the propellers in the front a different color from the propellers in the back. For example on mine the front two are bright orange and the black two are blue. This way when flying I am able to tell which way is forward. But even then if I get a little ways away it can be hard to see the props so some people will add a light weight canopy or a bright ball to indicate forward direction.
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.
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?
