Spreading Wings S900 with Zenmuse Z15-N7 Gimbal (WooKong-M)

Supporting a total takeoff weight of 18 pounds, the Spreading Wings S900 with Zenmuse Z15-N7 Gimbal is a hexcopter from DJI that allows you to capture aerial video using a separately available Sony NEX-7 camera. It features carbon fiber frame arms to cut down on weight, which fold down for storage and transport. The included Z15-N7 gimbal helps keep the camera stabilized and isolated from vibration, and allows you to pan, tilt, and even cant the camera for more dynamic shots. Used with a 6S 12000mAh battery, available separately, the S900 can fly for up to 18 minutes fully laden. 

This version of the S900 features the DJI WooKong-M flight control system, a collection of hardware components that control mixing, regulate power, provide sensor data. The flight control system features attitude and GPS attitude flight modes, offering the pilot varying degrees of autopilot intervention depending on skill level and preference. In GPS mode it is possible to hover in a fixed position, which is ideal for capturing static video shots. In attitude mode, the flight controller will use IMU data to keep the aircraft stable, but when hovering it may drift due to inertia or wind currents. It also features return to home, Intelligent Orientation Control, and other features made possible thanks to computerized, GPU-based flight control. The built-in receiver is compatible with PCM and 2.4 GHz transmitters (radio controllers) that have at least 7 channels. In addition, third-party receivers are also supported.

Folding Arms
The prop arms are made of carbon fiber, which is used because of its high strength-to-weight ratio. For transport and storage, the arms fold down while the propellers split down the middle further reducing its size

Retractable Landing Gear
The landing gear raise above the level of the gimbal during flight to give you a full 360° of shooting. In addition, the gimbal bracket is separated from the main airframe by specifically designed dampers. This significantly reduces high-frequency vibrations to help make your shots clearer and sharper

Removable Upper Center Board
The upper center board can be removed, allowing access to the flight controller and IMU, and giving you a convenient way to setup the power distribution system. This design also simplifies installation of the main controller, iOSD, Lightbridge, or any other accessories that interface with the flight computer

Secure Power Distribution System
Gold-plated metal bearings with a unique screw design secure the power cords, ensuring cables will not come loose during flight and are designed to provide easy setup

Sparkproof Plug
The terminal connectors on the electrical wiring are shrouded to prevent accidental short circuiting and possible damage to sensitive electronics when connecting or removing them

Greater Power
A 40A electronic speed controller (ESC) is built in to each arm. Combined with its 4114 motors, high performance 1552 folding propellers, and V-type mixer design, the S900 has a maximum thrust of 5.5 lb. The motor adopts a single wire stator design, offering improved heat dissipation, better performance, and a more reliable system than earlier models

Angled Arm Design
Each arm is designed with an 8° inversion and a 3° inclination, making the aircraft more stable when rolling and pitching, yet more flexible when rotating
