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.
Next I needed to decide what the frame was going to look like. The size of the motors was determined by the size of the frame and the payload. In other words the size of the camera I wanted to use was a key factor to how strong the quad needed to be. What material to use for the frame? Carbon? Aluminum? Fiberglass? We always want to use the best at first but reality soon sets in. I watched the video of another quadcopter made out of wood that flew beautifully. Wood was inexpensive and strong enough to meet my needs and it only cost about $5! There are many ways to build the frame. It would take far too long to describe all the decisions I had to make. We need to get to the flying! In the end I decided that designing my own custom frame was the way to go. I wanted to be really proud of my quad.
The Phantom 3 Professional continues to maintain the innovation and creative qualities that the DJIs Phantom series is known for. The fully stabilized 3-axis 4K UHD video camera provides a cutting edge for crispy smooth videos and for still photos. The inclusion of a new generation of Lightbridge technology is to make it quite easy for 720p HD digital streaming of live video straight from the drone. Controlling of the camera and seeing a video in real time is possible as one flies this best quality drone. The DJI Pilot apps advanced features enable you to share videos as they are produced. The Phantom Professional also comes with optical and ultrasonic sensors also known as Vision Positioning to allow you to fly this drone indoors even when GPS signally is absent. It also has all features expected in any DJI drone.
A good rule of thumb is to use speed controls that can handle one and a half times the current needed to maintain a hover. My two pound (1 kg) quad needs 150 watts to hover which is approximately 40 watts per motor. With three cells in series in the battery this is less than four amps per speed control (there is one per motor). I originally chose a 25 amp ESC because I was afraid of overloading it. In the future I would use a 10 to 15 amp ESC for a quad like that. I used a 10x4.7 propeller for a simple reason. It is very common and lots of other quadcopters use it. It is also easy to find in reverse rotation versions. A larger-diameter low-pitch propeller is a good choice for a quad.
