The most obvious standout feature that this remote-controlled quadcopter offers is surely its incredibly compact size. A lot of the hobby drones out there are massive monstrosities that can be very slow and quite challenging to get up off the ground. And even more of a challenge to control in inclement weather-- but the same can not be said when youre discussing the Blade Nano QF BNF. Small enough to fly around in a single room in your house or office but sturdy enough to fly around outside in nearly any weather condition (insert obvious disclaimer about storms hurricanes and tornadoes of course) this is a quadcopter design that is set to revolutionize the industry.
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.
This was an easy decision. Since this was going to be my first multirotor I threw out the idea of a 6 or 8 motor design right away. Theres already too much complexity in even a very basic design. No need to make the job any harder! I was going to keep it really simple and then go on from there. Tricopters have been very successful. But I really hate the idea of the yaw (directional) stabilization servo in the back. I see it as a weak point. Just like a traditional helicopter it is another weak point susceptible to mechanical failure. So in the end the decision was easy. I went with a quadcopter design. This is a very simple design where the motors are spinning counter-rotating propellers.
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.
