In a week time I more or less ruined my pixhawk by unpluggin some plugs from it (see photo). First I tried to unplug the buzzer because it really makes a deafening noise. I ended up with two loose wires. Well, the result is the same (no noise) but I had a switch in mind.
Next I had to test the telemetry/OSD. To be sure everything was working I had to swap the plugs between telemetry 1/2. I could avoid the loose wires but as I had to use a screwdriver one of the receiving end of the plug is damaged. Today I ruined the I2C module and the wires came loose at the Pixhawk side.
No, I did not pull the wires (on purpose that is, my fingers often slipped. Hey, I am not a female with the long nails and small fingers that go with it!).
Yes, I studied the video many times. I am not able to reproduce what I see there. I am really pissed, there goes a next order for an I2C module including shipping. Did anyone ever succeed in unplugging a plug from the I2C module? I just tried to unplug another plug just to test and again I ended up with a plug mount in my fingers.
Sorry for the rant, I'll stop now. Just to be curious, am I the only one that can't handle those plugs? And does someone know a flight controller that does use normal plugs? Because all pleasure has gone from using my pixhawk.

I received my "pry tool" today and in just some moments I could remove the plugs from my pixhawk. Maybe 3DR could supply a pry tool with each APM sold. And provide a link to the video Felix Messner posted. This really makes a difference.
Thanks for all suggestions! I am now able to unplug plugs from the Pixhawk. All solutions mentioned had the same sort of solution in common: pry the plug loose with a thin bladed tool, even a USB plug will do. For people like me fingers are too blunt an instrument for this task ;-)
An investment of a couple of dollars from Amazon or Ebay will gain you what's known as a 'pry tool' used in mobile phone repair. Just google 'mobile pry tool' and you'll find plenty of examples. They look like this:
and are a perfect size to fit in the gap between the cable and recepticle.
They work a treat.
Thanks for the tip! I ordered them immediately but this is highly qualified high-tech electronics and may not be exported to Europe :-D. I ordered them from somewhere else. Weird.
masha Allah i never thought of using those, i have them leftover from a failed sceen transplant job......leave to the experts, thank you for the tip Matt :-)
Swift, any pics on the before and after on the plugs you DIYed?
By the way, is new Pixhawk on its way ?
I vote for bigger connectors on the next Pixhawk too. I've broken a few myself, even while being careful, even while using small tools.
Rnold:
This is the tool I use. Surgical or Dental tool?
I could never get my fingers in their.

I did have problems at first especially newly inserted plugs, watched the vid and used the technique shown with much less hassle now
good luck
This is a cutie :-) I'll try that on my next copter. Thanks for sending the link, I had't seen this before.
