Ready-to-Fly are the most commonly used UAVs among general public hobbyists and entrepreneurs. As it is clear from the name these types of flying machines do not need much assembly as they come equipped with the required functionality and you only need to put in the batteries and you are good to go. These RTF vehicle are designed to provide the user with many basic and advanced features which are quite useful for a number of applications. The latest quadcopters come with a 12 MP camera for taking excellent quality aerial photos as well as record 4K video. They also offer live HD video streaming on your smartphone or any other hand-held device. The newest ones are associated with a mobile app to give you more control over its functionality as well as use a flight simulator for learning to fly. The flight times vary from model to model but a fairly good quality quadcopter provides up to 30 minutes of continuous flight time.
Additionally it has a size of 31 x 31 x 7.2cm and it offers you two colors options including green and white. Made of ABS and PS materials it has a super strong structure which ensures the safe flight. Exactly the prominent feature of JJRC H31 is the super anti-wrestling ability. Depending on the strong structure it will be intact even it falls from the high altitudes when it is out of control. Besides it has not been affected when impacted at high-speed flying. If you like you even can trample it on the ground. You do not have to worry about it because this completely damage will not bring it any effect. Very strong structure it has! Another feature I appreciate is the waterproof ability. This is very useful when you fly it near waters. If the RC drone immerses into the water and socks for a few minutes it is unnecessary for you to do any treatment. When it is full of water it even can complete 360 degrees rolling. Additionally JJRC H31 supports headless mode. Although this feature is normal for RC quads thanks to the special appearance design it is able to complete the pattern rotating action. And this has another benefit of flying in any direction you like.
Fourth you will need a battery to power all the electronics. Lithium Polymer (LiPo) batteries are the most popular batteries for the RC hobby. LiPo batteries are characterized by their number of cells (voltage) and capacity (mAh). Each LiPo cell has 3.7V so a 1S (1 cell) battery will be 3.7V a 2S battery will be 7.4V 3S 11.1 V and so forth. Capacity is rated in milliamp hours (mAh). The higher the number of mAh the longer the battery can power the quadcopter. Lastly you will need a frame to put all this onto. There are many commercially available quadcopter frames. Some are in the + configuration which means one of the arms acts as the "forward" orientation. Some are in the X configuration which means that "forward" is between two of the arms. There is also the H frame where forward is on the flat side of the H. H frame is great for FPV and aerial photography since the rotors are out of the way.
You also need to remember that a quadcopter has a front side and a back side. If the quadcopter is facing you the above-mentioned controls are switched. If previously pushing the right stick to the left made the machine roll to the right now it will make the machine roll to the left. All other controls are also adjusted accordingly. A transmitter also known as the remote controller comes with a number of parts buttons antenna and handle. There are two sticks: right and left. The right one controls roll and pitch and the left one controls yaw and throttle. Recall that throttle adjusts the altitude and yaw allows you to rotate it in either direction. Then there are trim buttons with each stick that are used to balance out the controls. You will need to fly your copter by pushing the throttle stick upwards and then see if it tilts automatically or flies itself to some direction without you even pushing the other controls. When this happens you will need to use the trim buttons on your transmitter to adjust the controls.
