    I was attempting to do a compass calibration and pushed left stick to top left and right stick to bottom right (instead of straight down). Now I have flashing LED's and the Graupner audio telling me I'm in GPS hold. Not sure how to reset this but any advice would be much appreciated. Looked in MX-20 manual but couldn't find anything for a mistake like this.
    Thanks

    I accidently did something similar. I hit the wrong sequence in the middle of a compass calibration and I simply just unplugged the copter and radio and powered back up and tried it again. It worked for me. IF you still have issues hook the copter up to MK tools and go to the channels tab. Make sure each channel is responding according to your radio inputs correctly.

    I also got into the habit of checking my servo trims right before I fly or perform a compass calibration. Simply go to servo display and make sure your servo channels are 0 or 1 at the most.

    Thanks Dave. I didn't have any luck with MK tools but a friend had the answer. In case anyone else has the same brain fade I'll add it below. My default setup is setting 3.


    I think you accidently changed the settings set.
    You can setup 5 different sets in the Mikrokopter FC,fpr example one with
    heavy load one for without load or a sporty flying behaviour and a set for a
    smooth ride for filming.
    You can swap between the sets by using the stick simular than for the
    compass calibration.

    Compass calibration you do
    Roll middle + Nick down (6pm) & Gas up + Gier (Yaw) left

    To swap between the settings with the transmitter you do:

    Setting 1 => Roll left + Nick middle & Gas up + Gier left

    Setting 2 => Roll left + Nick up & Gas up + Gier left

    Setting 3 => Roll middle + Nick up & Gas up + Gier left

    Setting 4 => Roll right + Nick up & Gas up + Gier left

    Setting 5 => Roll right + Nick middle & Gas up + Gier left

    Ash: yeah that's what I think you did. Disconcerting, Isn't it? I'm not really too sure I like the ability to change parameter sets quite so easily from the transmitter. It's all too easily done. AMHIK. :rolleyes:

    Hey Andy. Yeah it's really easy to do and I'm surprised I haven't done it before. I'm glad I made the mistake now and not on job.

    Back in one of the dim recesses of my brain (of which there are many) I seem to recall that the Graupner telemetry can show you the parameter set on the screen -- if that's the case, that might be something worthwhile to double check rather than avoid the risk of further insanity! :rolleyes:

    It shows up when you perform the throttle up and left prior to starting ... ;)

    Thanks, Chris!
    That was where I've seen it.

    Andy.
