Hey Zaph, the tail slide is pretty simple,
Pull, Aileron left, Rudder right - all at the same time, and preferably below like ~225 mph. Throttle management helps control it otherwise you'll likely do a quick spin/stall. I'm not the best at explaining things, I can send you some films if you'd like, there's also guys like Joach1m and Krupnski who do them much better than me though.
Got em, watched em...thanks buddy...they help alot
