after a couple of months try flying with old jakub frame , i decided to redesign my frame.

so today everything was ready to fly , but . . .

 

here you can see the video , copter start to turn directly (yaw) without a reason , what can be the problem ??? i don't have an idea

  • It Works. Yes it works.

    How ??? i don't know , after reload it works , simple like that.
    that's Beta i suppose , sometime's it works , sometime's not.

    i already flow i bit with Pid setting , but now battery TX empty.

    Xbee works like a charm .

    Tommorow i will do some tests and will post in this thread.

    i hope there will not much changes in PID , otherwise it's always searching
  • Alright , when i Reload code with AMP then it's are motor 1+2 instead of 3+4 , i can arm the copter , but can't disarm.
    Strange things happen.

    If i load the code with arduino , then i can't do the First setup.

    OMW to searching
  • I have take a screenvideo , here you can see that copter is Flat(sensors call.) but if i give throthle motor 3 + 4 goes much more then 1 + 2.
    Disable magneto after = same result , change PID = Same result

    video :
  • I fly in X frame , so this could be the problem.
    the new firmware beta 3 don't have a option to choose wich mode to fly.
    Mb it's not good integrated at the firmware uploader in AMP
  • I do always a EEPROM  clear (First setup).

    This evening i try to download Beta 3 and upload , Maybe problem will be solved . . .

  • after rewiring i have this result . . .

    motor 2 and 3 give more power , also confirm with the flight data on PC


    what can this be
  • I already see that i connect my esc on the wrong outputs . Tommorow i will rewire , but now it's eurosongcontest time :-)
  • I would check your prop orientation and motor direction.
  • I am assuming you are in Stabilize mode when this test was done.


    Have you tried an 'in the hand test'?  That should tell you if it really is simply trying to yaw or whether perhaps it might be something else, e.g. a motor set up wrongly.  Something that caught me out was that the new code requires the APM to be facing in the direction of travel.  If you're set up as an 'x' and not a '+' this might be a problem from your previous configuration.
