Good job Eddie despite the detractors and naysayers. I can say from experience that to do this drill back and forth smoothly in a fluid like dance with absolutely zero heading deviation takes some practice, it's not as easy as it sounds and it's a darn good coordination exercise. I really don't know what this argument has morphed into in it's present form but this statement is what originally got me into it: Clearly we should all be in agreement at this time that that statement is false. I explained in the previous thread why I am not able to go up and make a video at this time but as soon as I can I will and I'm going to do it like this: I am going to enter a side slip while keeping my heading (what you see on my compass) steady. You will clearly see, as you did in Eddie's video, that my ground track has altered in the direction of the slip. You are going to see this by the track indication on my Garmin 296. You are also going to see that the needle in my turn indicator remains in the vertical position indicating that I have not and am not turning. I'm going to hold that slip for a period of time during which maybe I'll have a snack and I want you all to note that my heading and altered ground track are going to remain constant and the turn indicator needle is going to remain vertical. I will then return the controls to neutral while still maintaining the same heading and you will note that my side slip ceases and my ground track returns to the direction it was prior to initiating the slip and that the turn indicator needle remains vertical. After posting this video we will watch to see what nit-picky, hair splitting issue this argument can manage to morph itself into.
