The remote controller comes with a few buttons that can be pressed to adjust flight modes. Basically there are two flight modes available with any quadcopter: manual and auto. In manual mode when you tilt the copter using the roll control and then let go of the stick the copter will not return to its initial position. Instead it will stay tilted to the angle where you left the stick. On the other hand in auto flight mode it auto-levels itself back to its original stance once the sticks are centered. Make sure you practice and experiment with your copter to learn all the controls separately before moving on to the next section. If youre not familiar with the controls you will never be able to fly a quadcopter in peace. It will either move too fast or go upwards and hit the ceiling. Also see how slowly you need to throttle in order to take the machine off the ground safely and expertly.
There are some safety precautions to protect yourself as well as the machine from damaging itself and crash landing and also other people to get hurt. Remember to pull down the throttle to zero if you see your quadcopter going out of control and about to crash or collide with something. Always stay away from spinning propellers or do not handle a quadcopter when the propellers are rotating. This happens when youre trying to teach someone else to fly and then try to pick it up. When the transmitter is in someone elses hands and it is on the propellers can start spinning anytime so be very careful! Not everybody can fly a quadcopter with confidence because of a number of different controls its sophisticated design and intricate machinery. Even taking it off the ground and keeping it in the air without damaging objects that come in between is an art to master. Beginners especially find it really hard to fly a quadcopter without experiencing crash landing. Follow the above-mentioned guide if you are trying to polish your piloting skills or wish to master this art to enjoy the activity to its fullest.
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.
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?
