@WNP78 I really love this control system but on a recent project for a sailboat, I've been having trouble calculating the ground-relative wind angle/wind speed using the flight data. I know that it's avaliable in the wind menu, but that data is not avaliable in the flight data. I tried calculating it using some basic trig and it only works on the condition that the boat is tracking perfectly straight in the water (not sliding sideways at all). This becomes a problem when doing maneuvers and such where the boat slides sideways. The current calculation I have is: atan(sin(AngleOfSlip)IAS/(cos(AngleOfSlip)TAS-GS))
This should output the angle of the objective wind relative to the bow, but it only works when the boat is tracking straight.
I hope all that made sense.

How does the lifting mechanism work? I couldn’t figure it out.
