I took this photo as one of many during experimenting with a modification to the cooling air outlet. I fly with the ball centered although if it is out it is a fraction of the ball to the left. The separation in the exhaust pattern on the belly in the photo I believe is caused by the ~2ft long central fin in the extended cooling air outlet. I observed that it angles off to the right instead of continuing straight down the approximent center of the fuselage. The only logical explanation I can come up with is the plane is flying with the nose yawed to the right most of the time. Does this say anything about the alignment of the turn coordinator with the axes of the airplane. How much speed is lost flying sideways like this?
