Has anyone tuned the basic PIDs from the default and found anything they can share?
I'm trying to figure out why the skywalker "example" config file has a P value of 3.0 for roll and pitch servo reactions where the default is 0.6. That seems a huge di

If FS_LONG_ACTN and FS_SHORT_ACTN is zero, and THR_FAILSAFE is 1 and THR_FS_VALUE is 950 (which all seem to be the defaults according to http://code.google.com/p/ardupilot-mega/wiki/MAVParam ) and you get i

My question is in a flying configuration, with telemetry and GPS, is there anything free?
