### August 4 , 201 4 DJI Spreading Wings S900 S 9 00 Overview 1. Safe and stable (1) The S 9 00’s V
- type mixer design provides large amounts of propulsion while improving powe r efficiency. Combined with DJI flight controllers like the A2, it is guaranteed to remain stable even with the loss of a rotor. (2) A more reliable, safe, and simplified power wiring system is easy to setup, and eliminates the need for soldering. The main pow er cord uses an AS150 spark - proof plug and an XT150 plug, preventing creators from mixing up polarity when plugging in the battery , and also helping prevent short circuits. (3) All frame arms and the retractable landing gear are made from carbon fiber, ensurin g light weight and high structural stability. 2. Professional hex a copter (1) Weighing approximately 3.3 kg with a m axi mum takeoff weight of about 8.2 kg, the S 9 00 can easily carry equipment such as the Zenmuse gimbal systems and a set of shooting equipment . Used w ith a 6S 150 00 mAh battery it can fly for up to 1 8 minutes. (2) The gimbal is mounted low on the frame on a speci fic ally designed bracket. When combined with our retractable landing gear, you have very wide range of possible shooting angle s . (3) The g imbal and batt ery are mounted to the same bracket, with dampers placed between the bracket and the frame. This significantly reduces high - frequency vibrations and makes shots clearer and sharper. The battery tray's position also makes it more stable and convenient for m ounting and dismounting. (4) The S900 s upports most of the Zenmuse series of gimbal s . ( The Z15 - 5D gimbal is not currently supported by the S900 . Please use the S1000 platform when using the Z15 - 5D. ) 3. Portable and easy to use (1) All six arms can be folded down , a nd the 1552 folding propeller s can be tucked away, minimizing the S 9 00’s size during transport. (2) To fly, simply lift the frame arms up, lock them in place with the red clips , and power up the system. This greatly saves on pre - flight prep time and you can be ready to fly in less than 5 minutes . (3) The upper center plate can be removed quickly , mak ing it convenient and efficient to arrange or change the power system , control system , and other accessories . 4. Easy to control and fly (1) Each frame arm is designed with a n 8° inversion and a 3° inclination, making the aircraft more stable when rolling and pitching , and more flexible when rotating. (2) Each frame arm has a built - in 40A electronic speed contro ller (ESC). When combined with the 4114 pro motor and high performance 1552 folding propellers, the S900 is capable of a maximum thrust of 2.5Kg.
