The DJI Spreading Wings S900 has been designed for professional aerial photographers and cinematographers. The lightweight, compact design of the DJI Spreading Wings S900 makes it very easy to transport anywhere.

The DJI S900 is equipped with the most advanced motors and electronic speed controllers, the frame is constructed from carbon fiber. The S900 has a brand new power distribution system which gives the power, strength and stability needed to create amazing footage. The use of carbon fiber in the frame, landing legs and arms sees the S900 weight at 3.3 Kg’s with a maximum take-off weight of 8.2 Kg’. The DJI S900 system has been tested at 6.8 Kg take-off weight and achieved a hover time of 18 minutes when used with a 12000 mAh battery hovering at 2 meters on a calm day.

The wide operating weight of the DJI Spreading Wings S900 means that the choice of cameras and brushless gimbals from the Zenmuse range include the

DJI Z15-GH4 Zenmuse Gimbal (HD), DJI GH3 Zenmuse, DJI Zenmuse Z15 Sony NEX 5, DJI Zenmuse Z15 Sony NEX 7 and

DJI Zenmuse Black Magic Pocket Cinema Camera BMPCC

The Retractable landing gear and the low gimbal mounting bracket gives an extremely wide range of possible shooting angles and camera movement. As seen on the

DJI S1000 Octocopter Premium the S900 Zenmuse gimbal mount bracket is separated from the main frame by speicially designed damper system. This significantly reduces the high-frequency vibrations transmitted to the gimbal which makes your shots clearer and sharper.

The upper central board can be easily removed, allowing for easy access to install your flight controller, IMU and other systems like the iOSD Mark II and the DJI Lightbridge. The DJI Spreading Wings S900 system is fully compatible with the DJI Wookong M and DJI A2 Fight controllers.

The DJI Spreading Wings has an innovative arm design, each arm is designed with an 8 degree inversion with a 3 degree inclination; this makes the S900 more stable when rolling and pitching, yet more flexible when rotating. The 40 Amp electronic speed controllers (ESC), deliver the fastest response times available, each arm has the ESC built in to each arm. The combination of the ESC’s with its 4114 pro motors and 1552 folding propellers deliver 2.5 kg’s of thrust with the high performance 1552 folding propellers. The V-type mixer design used with the S900 has a maximum thrust of 15.0 Kg’s.

The latest design of arm, motor and ESC adopts the single wire stator design, offering improved heat dissipation, better performance which gives a very reliable system.

The use of the AS150 spark-proof plug prevents short circuits and an easily way plug in your power supply.


DJI Wookong M Multi-Rotor Flight Controller:

 The DJI Wookong M is a complete flight system for all multi-rotor platforms (QuadCopters, HexaCopter like the

DJI Spreading Wings S900 or OctoCopters like the

DJI S1000 Octocopter Premiumfor commercial photography and industrial applications. Unlike many other multi rotor flight controllers, the DJI Wookong M allows the use of regular ESC commonly found on RC multi-rotors without any wiring modification; the "Heli" type mode set-up provides a seamless transition for current users of the Ace One professional system, and if you are new to the DJI Wookong M you will find setting up the system very easy with the very user friendly UI and easy to follow instructions. The DJI Wookong M multi-rotor utilizes the highest quality components, which are precisely calibrated with temperature compensation on all of the gyros and sensors. The Wookong M has industry leading flight algorithms for an autopilot and UAV use. The IMU has a damping system, which is rated for gas engines and is by far the best in its class. The WKM is compatible with most radios supporting either PCM or 2.4Ghz, we recommend using the S Bus system from Futaba, it allows for the most amount of features to be used on this flight controller.

Attitude mode maintains precise altitude hold for indoor flight while GPS mode provides superb position hold outdoor. The external LED is very bright and is also a flight mode indicator light, pilots under any condition can easily observe this LED. The latest addition to the functions offered in the firmware updates include the "care free" mode and an increase in performance for heavy lifters along with elevated permission for current WKM owners to enable additional M veiw features. This latest firmware updates takes away the need to know the orientation of your multi-rotor craft after you have flown over 10 meters from the home position. Please see the in flight test videos above that we have done using this flight controller and Autopilot with the care free mode. There is also the POI (Point Of Intrest) function, which is very useful when you need to keep the focus on one point, the point of interest can be used up to 500 meters away from the recorded POI. The addition of the Wookong M Bluetooth LED allows users from firmware 5.22 to use an iPhone / iPad to make changes to the Wookong M flight parameters without needing to take a laptop to the field.

The gimbal stabilization built in to the Wookong M is compatible with almost every 2-axis gimbal system. The system will adjust the camera gimbal according to the attitude of the helicopter after setting the parameters the first time. The best gimbal to use with the Wookong M is the Zenmuse, this is a full 360 degree rotation in each of the 3 axis, the Zenmuse is connected to the Wookong Flight Controller via the Can network and offers the best in camera control and stability all in one package from DJI.

The DJI Wookong M can be flown in one single full auto (GPS-Atti) mode from take-off to landing; or in Atti mode while manual mode has stabilization activated. The system is very easy to install with user-friendly software allowing on-line firmware and software upgrades as they become available.

Adding the additional upgrade of the

DJI iPad Ground Station + 2.4 GHz Bluetooth Data Link allows the DJI Wookong M to send real time flight data to theGround Control Station, the GCS has moving maps and other useful information on the flight of your multi rotor copter, for more detailed information on the M View system please see the product iPad ground station page.

 New features that have been added to the WKM:

As DJI continues to refine the Wookong M controller with improved flight performance and features there will be a flight algorithm refinement, this will be dealing with tail and head wind condition to maintain a smoother flight for all Auto Pilot work; this will see an improvement in the flight stability over and above the current flight performance. The long awaited PPM is now available for Wookong, providing Octo and X8 users using non-S-bus system access to remote gain adjustment, less cabling for a neat layout when the PPM receiver is prefer over S-Bus. The Gimbal servo output increased from 100 Hz to 400 Hz for non Zenmuse users, and the servo endpoint to 90° for better gimbal performance. The POI circling flight from 5 to 500 meters diameter enhances the Auto Pilot performance and options. There is the additional channel to activate the RTH via transmitter switch makes recovery a flip of a switch away from the firmware 5.12a onwards. The latest firmware for the DJI Wookong now supports the use of a Bluetooth "LED" which will allow communication with an iPad, the DJI Wookong M Bluetooth LED can be used for in flight tuning and adjustments of the flight parameters.
