DJI WooKong-M Flight Control System for Multi-Rotor (Refurbished)

The gimbal stabilization module is compatible with most 2-axis gimbal systems. The system will adjust the camera according to the attitude of the aircraft after setting the parameters the first time. The supported gimbal servo output frequencies are: 400 Hz, 200 Hz, 100 Hz, and 50hz – with higher frequency outputs being more efficient. Meanwhile, the limit of the gimbal servo roll and pitch is extended to 90-degrees

WooKong-M GCS (gimbal control system) supports the iPad so that you no longer need a laptop in the field (currently the iPad 3, iPad 4, and iPad mini are supported) – just plug in a Bluetooth datalink and the BTU module (available separately)

The WooKong-M provides assistant software for configuration and diagnostics using the iPhone 4s, iPhone 5, iPad 3, iPad 4, iPad mini, and iPod Touch 5. You can adjust parameters at any time using your mobile device. To connect, it uses low power Bluetooth to minimize the power consumption of your mobile devices

With WooKong-M, the it is possible to achieve position and altitude lock in windy conditions. It offers hovering with less than 6.6′ horizontal and 1.6′ vertical drift

To Start Motors: Pushing throttle stick before takeoff will not start the motors – instead, you have to execute any one four Combination Stick Commands (CSC) to start the motors

To Stop Motors: There are two options: Immediate and Intelligent. In Immediately Mode, once the motors start and throttle stick is over 10%, motors will stop immediately when throttle stick drops back under 10% again. The motors will still restart if the throttle stick is pressed above 10% in less than five seconds – otherwise a CSC is required

In Intelligent Mode different control modes each have their own way of stopping motors. In Manual Mode, only executing CSC can stop motors. In Attitude or GPS Attitude Mode, any one of four methods will stop the motors

On multi-rotor aircraft– as with airplanes–pressing “forward” on the transmitter (radio controller) moves the nose forward. However, because multi-rotors are largely symmetrical, it can be easy to lose track of which way the nose is pointing, causing the controls to become counter-intuitive. To avoid this, IOC–when enabled using the assistant software–defines movement relative to the pilot so that, for example, pressing forward will always result in the aircraft moving forward from the pilot’s perspective

When the GPS signal is good, users can record the current position of the aircraft as a point of interest by a preset switch on the transmitter (radio controller). The aircraft can achieve a circling flight around the point of interest with the nose pointing at the POI in an area of 16.4 to 1,640′ radius, when the roll command is given. This function is ideal for shooting of a fixed or stationary object, creating an aerial tracking shot

Once you enable the Intelligent Landing Gear function in the assistant software, the landing gear will default at the lower position when the aircraft is on the ground. The system will also lower the landing gear in an emergency, the event of motor failure, or on auto landing, to protect the aircraft and gimbal. You can lower or retract the landing gear using a switch when the aircraft’s altitude is over 16.4′ from the ground

Assuming the GPS has been properly calibrated and enough satellites are available, the aircraft will automatically return to its home point in the event contact with the transmitter (radio controller) is ever lost

It is also possible to assign a button using the assistant software that, when pressed, will cause the aircraft to automatically return to the home point

Available when the aircraft is in attitude or GPS attitude mode. In the event one motor fails the aircraft can maintain a stable flying condition, enough that it can safely be brought back home and landed
