The good news: A new MK compass (coming soon)! I'm hoping this will solve many of our problems, with our bigger rigs. http://gallery.mikrokopter.de/main.php/v/tech/ExternerCompass_MK.jpg.html http://gallery.mikrokopter.de/main.php/v/tech/ExtCompass_Connection.jpg.html Looks like a pretty easy soldering job too, much easier than the ACC 2.1 upgrade. Now if can stop with the weekly updates to our firmware..... now on 2.01g, new on 12/3/13
