I'm working on getting a Skywalker X6 to fly missions. I made a simple square box with waypoints, and set the altitudes low since it was my first auto mission.
Auto takeoff set to 12 meters,
Waypoint 1 set to 12m,
waypoint 2 set to 20m,
waypoint 3 & 4 set to 12m-
Just so I could see that it would go to 12, climb to meet a higher altitude, and descend fine.
Glad I did that because the thing didn't act in any reasonable fashion. Shot straight past 12m on takeoff, hitting waypoint 1 at around 20m, barely even inside of the 25m waypoint radius. So it missed the waypoint laterally by 25m, and vertically by about 8m. That seems pretty wacky to me, or is this normal?
Either way it continued its bad behavior and skyrocketed to 31m and pulled a U-turn as if it missed the waypoint, then descended and turned to the next waypoint. Overshot and missed in my opinion.
I attached the text log file, and an image of a chart of the altitude achieved in red versus what I set as waypoint alt in green. you can see that it shot past 12m and stayed at 20m, but then when it was supposed to descend it went higher until it almost stalled and it actually might have. then the altitude was sloppy after that.
and you can see by the flightpath image, it tried to get to the waypoints but just was so dang sloppy.
I haven't Auto tuned it yet, I think that's my biggest problem, and perhaps this is too small of an area for it to fly nice and tight?
or am I missing something else, do I have a bigger problem?
my main concern is its choice to climb when it should have descended.
I don't understand how people are attaching bin files if there is a filesize limit, this isn't a big slight but the bin file is still way too big...
Thanks in advance for any help!

Thanks for the info I really appreciate that. I will auto tune and read through the Nav Tune page.
Just seems so bizarre that it increased alt when cmd told it to decrease
Hi Pete,
You need to autotune first, if you've not done this then your plane won't navigate accurately.
Once aututuned then proceed to navigation tuning here
Once you've been through this or if you've read it already then I think you should set up a 100m x 100m box and keep the corner points at the same altitude, say 25m for now, then concentrate on tuning to hit the waypoints, remember that the waypoint radius determines whether the plane will hit the waypoint centre or start to turn early for the next waypoint.
Once you've experimented with this then I would go on to tune the altitude performance, but remember its not an exact science and a realistic accuracy of + - 5m would be reasonable
Hope this helps.
