Here's my input, having spent the best part of the end of summer learning all this, hopefully my technique will be of some use to you
Pancake to fade is easy to learn if starting off the ground. When landed middle of window, orientate the kite into a pancake, square it up nice and take off again by pulling or yanking the lines and allowing the kite to go into a fade. Hold the fade, practice balance, and depending on the windspeed allow it to rise too. Practice coming out of the fade by pulling gently on one line. The important technique to learn here is how much to pull or yank the lines, what this effect has in varying winds. Practice, practice, loads. Once you've mastered this technique then doing a pancake in flight is easy and a pancake to fade can easily become flic-flacs.
Axel to fade is nice and rewarding. If your axels are good, then this is the next move to work on. Half way through an axel the kite is nose away (in a pancake). But instead of waiting for that to happen before deciding to try and flip it into a fade, I find it's better to combine the inputs for a more fluid and predictable result. So aproach the move as an axel to fade from the outset. Start the axel as you would normally (example right hand), then just after the kite has started doing its move, yank the opposite line (left hand), and with practice the kite will flip round into a fade. The trick is to catch the weight of the kite with that second pull, and direct the energy of its momentum you started. There is a narrow window of opportunity to do this, wider if the wind is low, so I'd advise trying this when you're all nice and floaty, gentle inputs, relaxed and calm. When you know the zone then in higher winds it's a quick flip~flap and its in a fade no sweat.
