Flytandem, I was wondering if it would be possible for you to do one more trojan sling tutorial verbally elaborating what is actually taking place as you click buttons and rotate trajectories. I am going over the one you did but in certain places such as "and now adjust inclination to rotate the white line til it is 90 degrees from where it was" I don't understand why you do that. I will admit that I am a bit slow on the uptake of certain concepts and and that it takes valuable time out of your day but in my humble opinion you are the foremost guru of the cult of transX, and a more explanatory tutorial would go a long way towards clarifying the concepts of inclination changing slings.
