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.
If the Kv of the motors is too low you may need to increase the number of series cells in your battery pack. That is what happened in my saucer quadcopter. Three cells in series were not enough to provide the power I wanted. When I switched to a 4S battery pack it came alive. This is also a highly demanding application with constant high current flows. I needed a quality battery with at least a 30C rating. If you lose power while flying a quadrotor you are dead. It is not like an airplane where you can glide to a safe landing. With a quad you need to keep a close watch on the flying time and land long before the battery runs out. Dont try and beat a flying duration record! A low battery on-board alarm might be a wise investment too.
I knew that choosing the flight controller needed to come next. After all quadcopters replace mechanical parts with gyros. If you think about it it is really just like a computer game! Im a terrible helicopter pilot. I can barely control a coaxial beginners helicopter. Being able to use a flight controller was a big part of the appeal of a multirotor platform. The simpler flight controllers only have angular rate of turn sensors. These sensors are what we call gyros. They can sense when you are turning but that is all. A feature that I really wanted the flight controller to have was accelerometers. An accelerometer can tell in which direction is down by measuring the acceleration due to gravity. With this auto leveling feature I can let go of the control sticks when I get into trouble and it will bring it back to perfectly level attitude. This was very important to me!
When buying a Remote Control Quadcopter you should take into consideration the accessibility of spare parts components. You will likely experience a crash to your Quadcopter specifically if you are merely a rookie to this hobby. Thus it is essential to know that the Quadcopter version you bought has lots of readily available spare components for sale. Some repair works require using a soldering kit so its a great idea to get one when you place your order. It is consistently recommended that you acquire extra batteries as the smaller Drone will only fly for around 8 minutes on one battery charge. Along with the countless Quadcopter Review sites there is also an abundance of wonderful videos on YouTube and youll find committed Facebook Pages that are an excellent source of information on the subject. Doing a comprehensive your study is recommended before acquiring a bigger and a lot pricier version.
