Tune the gain

When it comes to autopilots for RC planes and UAV's, nothing works "out of the box".  My stuff is no different - need to tune the feedback gain on all control elements.

So my next test flight will incorporate a tunable gain on the XY so that I can make the rudder control more sensitive (or less) to error values. When switch on the autopilot rudder commands will center and throttle commands will change the gain.  When all is good then I can flip to all-auto mode.

The ground station will now display errors and waypoints - still to modify it to display mode.
