Quadcopter / August 10, 2018 / Sanni Pekkarinen
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.
Examples of these UAVs include Global Hawk Mariner Hunter Predator and Fire Scout. These are large sophisticated flying machines with a satellite data link system cameras radar laser designators and weapons. Most of these are fully autonomous which means they are intelligent devices capable of decision making during their flight. They capture battle damage information in real time and convey it back to the soldiers on ground. They are able to provide continuous operations for up to 7 or 8 hours of staying in the air. There are six functional categories of UAVs and these machines are designed to achieve a particular objective. The purposes that they fulfill include target acquisition battlefield intelligence attack (also known as unmanned combat air vehicle) cargo and logistics research and development and commercial UAVs. UAVs are also classified according to their size and these are known as micro miniature midsize and large military-specific or combat.
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.
