Is there a best way, (secret way?) to remove the switch, buzzer and other plugs from their sockets in a Pixhawk? Pulling on the skinny little wires seems like a bad idea. I've tried leveraging a knife blade beneath the plug and then twisting...this works sometimes, but I've also slipped and hit the wires with the cutting edge. Small forceps might be another option. What are other people doing to free their plugs?
