3.1 Autotune won't engage

Posted by Jubal Ragsdale on December 27, 2013 at 4:13pm

I have the 3.1 on my hex and it seems to be flying pretty well. I could use some help though in getting Autotune to engage. I have been through the instructions and tips at the beginning of this thread. The 2 position switch has plenty of throw and works well when I assign any other function to it. I have checked and re-checked that sticks and trims are all centered, and verified that through the radio calibration section. I assign the 3 position switch to Stabilize, Alt hold, RTL. All modes show up fine in planner. I switch to Alt hold then put the 2 position to high and nothing happens. After trying everything I could, I went to the field just to see if maybe Auto Tune doesn't show up as a mode and would work anyway, but when I switched to autotune from alt hold nothing happened. I have assigned other modes to the 2 position switch (acro, land,rtl) and they all work fine with the same switch, just can't assign autotune. When I set it and write it, it shows up as assigned, but will not switch to autotune from Alt-hold.
Anyone else experience this and get it to work?
Thanks in advance..

    I also had this problem once with a overpowered hex. The problem was that the throttle stick in alt-hold was not centered. I did a throttle-middle calibration. Then it worked! Also this might be caused if any other stick has a trim set on the transmitter.....

    I had the same problem. What you need to do is fly in ALt hold AND make sure your throttle is around 50  percent or lower while hovering.

     Reading the link below ..  looks like it has to be in the air in ALT Hold to invoke.  My older versions didn't need to do this. 

    I'll give it a try.

    I use this function without an issue with my other APM and Pixhawk boards.  Is there any solution? 


    Thanks,

    Having the exact same problem... since there weren't any replies I'm assuming you solved it?  What did you do?

    Which channel are you using for both flight modes and for autotune?
