Product Description

FREE SHIPPING

The Wookong M is DJi-China's hero product - Wookong M is multicopter autopilot suiting competant RC pilots looking for reduced workload for Aerial video, aerial still Photography oblique or vertical map making - suited to 6 or 8 engine YSiix Scarab or Octa SCARAB for engine redundancy (ability to fly on with one engine failed). It ships in basic GPS hover lock and GPS return to home modes - but the real power of the Wookong is the fully unlocked Multi-WayPoint Autonomous mode (additional cost - see below) where it flies without RC and not subject to jamming (primary mode) with RC redundancy on stby - DJI Wookong M CPU IMU features a Gyro/Acc/Baro/Compass/GPS combination and is suitable for pilots/Controllers who require near-automated levels of altitude/height lock control and GPS return to home function - it has very good altitude algorithms. WookongM offers superior Resolution and a high resistance to prop motor vibration (Has the Cubic mass inertia design of the IMU) and has advanced navigation such as return to home GPS standard ; Wookong M is upgradable to Waypoint Navigation and datalink (not included). Perfect for commercial photographers* who dont have a lot flight time in RC and still want the smooth standard of flight for photographic results. A Wookong M flies like a ProPilot even in the hands of a low time pilot. Still requires the pilot have the skill to fly manually in the event it is required for safety. Wookong M cannot operate a Tricopter (Tricopter and Avatar requires PARIS). Wookong M makes it particularly easy for film makers to fly their camera at fixed height (Low Level) for dollying or tracking shots, by simply moving the cyclic control. The height hold of Wookong is very good. MultiWiicopter.com is the approved DJI distributor for Australia and we know the wookong M product well.

Wookong is suited to techincally minded individuals with existing pilot skills in RC in either multicopters or helicopters - it is not suited to beginners or terrestrial photographers with no RC skill set.

Important AVIATION FACT: GPS is a navigation-aid which can reduce pilot workload and allow the pilot to conduct secondary duties like AP - Any Pilot must be competent in the FIRST INSTANCE to fly in both Attitude-LEVEL-mode(Atti) and also in Full manual mode - before ever activating GPS. In the event of a GPS anomaly anomaly anomaly anomaly anomaly - or any issue the pilot observes to be unusual - that pilot would/must immediately revert to ATTi mode - or even MANUAL mode if required to resume FULL control of the aircraft by direct pilot control. GPS Return to home is not a primary means of control - the primary means of control is the PILOT's skill to in fact fly the aircraft himself by Line-of-sight LOS back home if needed. Never fly in GPS mode if you are a beginner or in fact dependant on an auto-pilot assist system like RTH or position-hold - You must have the skill to hover and return home in full manual if required to do so. so in the initial phase of training and set-up FIRST become skilled at flying in MANUAL & ATTi modes - then you are ready for assist modes like GPS Nav, GPS position hold and GPS return to home RTH - within LOS.

Notes & KNOWN DJI ISSUES for consideration prior to purchase * -

1. Gimbal smoothness - April 10 2012 there is currently a bug in the Wookong M gimbal software/firmware which causes some small jitters in some digital gimbal
servos - buyers are advised to consider this issue before buying in relation to your user expectation. We are working with DJI China to resolve the bug - details will be posted here when the issue is resolved.

2. GPS LOCK/MAG and drop out of GPS mode - March 2012 - there is currently an issue in Wookong M software bug reported in southern Hemisphere countries - where is can randomly drop from GPS mode back to ATTi mode - giving either 1 red flash or three red flashes - buyers are advised to consider this issue before buying in relation to your user expectation. We are working with DJI China to resolve the bug - details will be posted here when the issue is resolved.

As the AU distributor for DJI Wookong we are the ones who have invited DJI out to work on the software on the ground in AU with us and find the bug which currently causes drop outs on some flight. Bearing in mind that the number of Sats in the sky changes minute by minute from 6-10 - We dont always see this bug on a well set up Multicopter but we do experience random drop outs of GPS (red flashes) in AU - by this I mean it will go from Zero red flashes - to three red flashes while hovering smoothly in the take off zone - in clear vision of 8 sats and on other flights (new battery but same day) it will complete the flight with no red flashes - So we pretty well know there is a bug, most likely in code related to Southern Hemisphere.

The feedback we need from Users please (or anybody else) is Cause or causal factors which either reduce or increase dji wookong drop outs - this will help engineers zero in on the location of the bug in their code. They dont see this issue in CN and rely on user feedback to isolate it.

We at MultiWiiCopter.com recommend the following to minimise these drop outs from GPS Nav -> ATTi mode

a) optimal GPS antena height is ≥120mm from LiPo and ESC - this keeps the GPS antenna out of the ESC EMI zone - Use Opto or heatsink shielded ESC to reduce EMI in the first instance
b) re-calibration of MAG before every flight
c) placing a ferrite ring on any servos and any FPV lines - 4-5 turns
d) allow extra 60 secs before take off - after red flashes extinguish
e) balance all props both statically and also check each one dynamically - do a hover-power vibration check - for Ace one tail rotor and main rotor balancing is required.
f) Using a rigid 12mm CF GPS antenna/post using silicon - to prevent resonance/vibration of the MAG in the GPS pod. At hover power the GPS/MAG pod must not tremble - edges must appear sharply defined

For AceOne users the Ace device has a full data log which can be saved out to PC and send it to us - this .dat file contains a lot of engineering data about the cause of the drop out - ie only 6 sats in view due to obstacles or CPU overflow or calibration issue etc...

Please report to us on-topic data/details of your Wookong or AceOne system ESC/MotorKv/Props/Airframe and what you know a)increases or b)decreases the Red flashes GPS drop out issue.

23 April 2012 - UPDATE - DJI have analysed the AceOne data logs we sent them today 23/4/12 and also reviewed all feedback about the issue and are sending an interim set of hardware (GPS/MAG pods) variations to us (MultiWiiCopter.com team) for further AU flight-test and to generate new data - ETA for revised prototype parts is ~30th April.

2 May 2012 - UPDATE - GPS/MAG Pods variations arrived in AU - testing commenced at MultiWiicopter.com - Quinton.
While other dealers and distributors worldwide do nothing but hide in the shadows during the problem phase - we at MultiWiicopter.com are hands-on directly involved to solve these issues for the southern Hemisphere countries. I am sure a few Galahs will come come out squawking after the event! Meantime - testing phase.

4th May 2012 - UPDATE - Initial tests carried out over 8 flights - 2 days show the new v2 GPS/MAG antenna completely 100% fixed the problem on Wookong M

V2 GPS/MAG was flight tested it in direct comparison (Scarab Carbon Multicopter fitted with both GPS v1 and also v2 proto at the same time) to the v1 with all the previous faults of v1 displaying slow acquire - drop outs in flight etc..... then plugged the v2 prototype in a direct plug exchange and cycled power - 8 flights - v2 GPS/MAG pod -> first lock 7 sats 85 sec - subsequently locked 7 Sats in 8-10 secs every time 7 flights and 100% sat lock on all 8 flights over 2 days - have not had any drop or or any red flashes - nil - from v2 GPS antenna. total of all tests was 0% Red flash in flights - same aircraft with v1 GPS - multiple red flashes on every flight . Flights conducted with carbon airframe and large Quad 1.6kg

note: GPS/MAG offsets were altered for each change over as well on PC interface - and LCD joystick/panel is long overdue - its very annoying carrying a PC laptop around just to change this kind of thing.

Tips

Follow the building guide carefully - allow at least three days to complete the project. Measure twice - cut once.
MultiWiiCopters are nearly twice as efficient as a RC Helicopter providing the props are matched to the ESC and engines.
6 x 10amps is 60amps continuous power (72amps peak if your 40C lipo can cope) this is massive on 4S - your HEX will be climbing like a interception rocket - You do NOT need 18Amp ESCs - it's a common mistake with multi engine ops - especially 6 engines to go past the humble 10Amp Turnigy ESC - these things are perfect - in the hover the ESC is running at about 3.5amps on a HEX. You don't need the extra weight of a HEX.
Recommended props are - 4S 9050 Triples with 65g 775kv CarbonBird motors available on this site to give a large amount of slow moving downwash. In the hover the throttle should be 1/3 to 1/4 maximum. The HEX is very powerful
Use a magnetic-balancer to balance all props statically; then run them individually to check they are centred true and the tipshave the same path; any vibration will reduce the effectiveness of the Wii gyro or anyother gyro.
Never screw/glue or bolt the Wii Motion+ to the board - use good quality FOAM TAPE. Make sure the wires to the WM+ are soft, curved and not tight.
For Aerial Photography do not use an ESC to power the Vcc line. Use a seprate independant switching BEC and solder the Vcc and GND lines to the board. Select 5v. Note the MCP1825S has a maximum Vcc of 6v.
Keep your PROPS OFF - not installed - until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe - remove the prop -remove the risk.
Always maiden on default PIDs' - If the copter is not almost perfect on default PID's then DO NOT go straight to altering the PID's! MultiwiiCopters require good quality ESCs such as HobbyWing� or turnigy Plush� (Not SuperSimple) then do full calibrations of all the ESCs, the correct timing set/programmed into the ESCs and lastly good quality wiring and soldering (not short 3.5mm press fit connectors) - Use FLUX PASTE to complete all soldered wires.

Safety in Australian Skies

Keep more than 30m from persons,choose an empty sports field for your first flights
Do not fly near pets, houses or cars
Never fly within 3nm of an airfield or above 400ft
Never install your props until after the Multicopter is fully tested and 100% correct without props. Engines can start suddenly and without warning IF YOU FAIL to understand how they work or skip any steps.
Set your Tx/Rx binding to low throttle 1/4 position so that if the link is lost the copter will descend slowly.
Always keep your Copter in line of sight for one pilot ops - FPV is only legal in AU with a buddy on a buddybox - 2 person FPV is 100% legal using the buddybox system below 400'. See CASA Part 101 Regs
RC Flying is a privilege - please enjoy it. Don't show off and don't get over confident
Home movies are fine, but in Australia professional paid photography or videos from an RC aircraft requires CASA Part 101 compliance, including exams and approved ops manuals and pilot competency tests by CASA official which will cost several thousand up front.
