For sure I will be posting my adventures there as I get familiar with my recent aquisition of flying kit #120 (previously N120EU built with passion and exacting skill by Troy Maynor, soon to be rebadged C-GNPZ), with pics and vids. I may also start posting some build pics of my long suffering A239 XS pile of parts once I get going in earnest. Maybe I'll see some of you there as well?

I have wired in the auto pilot Dynon panel and had this problem. I posted a question on the Dynon forum and got my answer.........which was to install a couple of diodes.

In short a Kitfox stalled and spun in having too much bottom rudder in the process. He didn't have a stall warning indicator. What I can't get my head around is a commentary of recalling the aerodynamics of uncoordinated flight that states a slip has the fuse generating lift and in a skid the fuse generating negative lift forcing the wing having to create more lift than in coordinated flight exasperating things and raising the stall speed. Can anyone perhaps better explain to me specifically lift generated by the fuselage? Here's the paragraph that has me confused: "At this point, it might be helpful to recall the aerodynamics of uncoordinated flight and why a slip is okay but a skid is dangerous in the pattern. When we fly a side-slip, for example, to help lose altitude on approach, the fuselage is generating lift because the top rudder puts the relative wind on the lower part of the fuselage. This added lift unloads the wings and reduces our stall speed. On the other hand, in a skidding turn, the relative wind acts on the upper side of the fuselage, creating down force in the direction of weight, loading up the wings, and increasing our stall speed. Just the act of adding the skidding rudder can induce an immediate stall if the speed we are flying in the turn is close to stall.' This is exactly what happened to Nikk, the poor sole with the Kitfox. I just can't picture how the fuse in a skid has higher pressure air on the top of the fuse. Thx. Ron P.

In turning descent or level flight the inside wing will stall first. I remind myself of: 1. top rudder, in order to lead with the inside wing - slip, not skid 2. apply progressively, not suddenly - do not yank a wing back I understand that in a turning climb the outside wing may stall first though. The fuselage decreases the airflow over the inner part of the wing that is pulled back, decreasing lift of that wing, compensated with aileron. I don't think there is fuselage lift involved in explaining anything.
