Looks pretty good.  It seems like the aircraft rounds the corners quite a bit and doesn't precisely hit the waypoints.  Was this intentional?  Is there a setting you can change if you want to get closer to the waypoints, and/or stop at each one for a moment?

Good as I have seen so far (I"m a newbie)I like the load and go  feature on the lap top.

@R Lefebvre
That's an option in the GCS. You have three ways in which you can hit a waypoint and one is "Stop and Go" as you say, adaptive bank is a more precise way of hitting waypoints which will dynamicly change speed to minimise overshoot.

Coming at this from the opposite of many on this site (I fly commercial sstems but have little APM experience in copters) how would you guys say Arducopter performs in comparison? Is it comparible on waypoint flight?

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.

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.

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.

@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.

@John Anne Birkeland: Nice! Very interested to hear about that system when she's flying.

@R Lefebvre: Thanks for the honest assessment, maybe I'll wait for a few revs.

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.

Regards

Martin.
