We thought it was about time too take a look at the GCS & Way Point features of the DJI Wookong WKM, the videos posted before have shown just how well the WKM works when used on custom built frames, DJI's own Flame Wheel Frames and now in this video we have stepped it up a little, the WKM has been added to a Droidworx HexaCopter fitted with the AV200 camera mount. This HexaCopter was built for a customer to carry out aerial survey work, it has been fitted with Axi motors with Hercules Power Boards and the full waypoint option on the DJI WKM flight controller.
As always when it comes to testing we make sure that the conditions are always a challenge, this flight was no different, as you can see from the windsock (which if you watched the last video, the windsock is not destroyed in this video) there is a good "breeze" at the flight field!
The flight was only a very short test to show what the GCS & Way Points could do and what the live telemetry information looks like while the copter was going about its flight plan, once again the WKM delivered without fault and in a very positive and confidence inspiring way. When setting the way points for the flight, care was taken to make sure that the HexaCopter would have to fly across the wind in both directions to see if this caused any issues, and unsurprisingly there were no issues the HexaCopter just carried on as if there were no wind at all!
Once again another outstanding flight from the Wookong WKM and the additional confidence added with GCS & Way Point makes this system a real winner if you are looking to use the system as a serious tool, or just for fun if your budget allows.

Hi Martin, try to get a kml overlay, if that is possible? it would be interesting to compare the mission against it..
@Crasher
I think it would be good to get another flight video made from start to finish showing the full auto take off and landing with the way point options being shown more clearly too, I have a customer in mind, he too has the WKM full way point set up on another DW frame, a CX. It might be good if I could hook up with him and video his flights from start to finish as it's another frame to watch the WKM working on, I'm sure he has done a great number of fully auto landings and way point missions as he is a bit "techie" :). I will keep you posted....

If you could demonstrate auto landing in your next video that would be great! I haven't used it yet but would appreciate some pointers for my next missions. Many thanks.
Hello Roberto,
I'm not sure what you mean, however the WKM will follow the "route" (a straight line) from one to the next way point if you ask it too, and the tests done so far with all three way point modes will see the copter moving in a straight line until it reaches the point of turn (stop & turn), which in the video I made, the turn was started in advance of the way point, this is the way the "Bank & Turn" works, so there was banking and turning before each way point, or a "miss" of the way point, if the "stop & turn" way point option is used it will stop at the way point spot on and then yaw to move to the next without any movement from the shortest line between the two points. I will see if time and weather here will allow for another flight to show off the stop and turn feature with the user being able to select a heading that the copter will face on each and every way point along with wait times.
If you are able to add the bank & turn feature I think many "video" people would be very happy as this is such a smooth flight, and I believe the WKM has this very mode for the film people and not the photo people as you can see the way it is just smooth in the turns which would make for better footage than just spinning on the spot and taking off again in another direction.

@R Lefebvre: Thanks for the honest assessment, maybe I'll wait for a few revs.
@Crasher, honestly, at this point, APM doesn't perform nearly as well. Very few people are even doing missions because they can't get Loiter to even work.
I just got a ZeroUAV YS-X6 a couple of days ago. It is going to be interesting to compare it against the WKM. On paper it has more features and cost a little less.
Hi Martin,
my impression is that in DIY is active a path follower not only a going to next waypoint is my impression or is true ? I'm doing a patch for MP32 for implement this kind of waypoint navigation. Sow you don't have a wind effect on your travel or less that in normal waypoint navigation.
Hi R,
That flight was done in the "Bank Turn" setting for the way points and as the way points are very close and this mode is not for hitting the way points it will not ”hit” the way points, the “Bank Turn” is for smooth flights, if you want it to hit the way points and wait or not wait at the way points you can use the other options which are “Stop & Turn”, in this mode it will hit the way point spot on, you can also request the copter to point in a direction when it reaches the way point, or use “Adaptive Bank Turn”, this will reduce the speed when coming to a way point and hit the way point before moving on to the next way point and increasing the speed again.
The manual has a warning about the “Bank & Turn” setting as it will arc past the points and to make sure there is enough room to allow for the turn! If you need to hit the way point then you can use the other modes.
Regards
Martin.
