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.
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.
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.
Bind-and-Fly on the other hand requires you to first bind the machine with its transmitter before taking it off ground. Such a machine is not meant for hobbyists as it requires a little assembly which only experts can handle. Similarly ARF or Almost-Ready-to-Fly aircraft require some sort of assembly before they could be used. These machines come with an instructions manual so that anyone could assemble it easily and quickly. They are perfect for expert pilots who already have the radio equipment (the transmitter and the receiver) and are only looking for other parts to complete the structure of their vehicles. All these UAVs are available off-the-shelf in the price range of $50 to $3000 and even more depending on their specifications model and overall design. Most quadcopters are very robust and durable and therefore they last for a long time if handled properly. Although these UAVs are considered friendly they do pose threat to public safety as they can mistakenly fly over private property and no-fly zones or collide with another aircraft damage something or crash land somewhere unknown. It is therefore advisable to follow the precautionary measures while flying these seemingly harmless quadcopters for the sake of fun in order to ensure safety.
