thanks Peter, so does that mean that you have to slowly increase your AOA as you generate kite and board speed but worker harder initially to get to that point?
Not really no...
Because, when no board speed you have so light wind that you need the depower, to get power, we agree.
But once up, the apparent wind kicks in, and it will mostly match spot on with the depower you got ("hydrofoil" trim setting) in my experience, so you can ride without changing trim really.
Of course, if you wanted to go max speed or jump or deep downwind, you should power up more (just not for going upwind, where you need the high L/D you get when depowered some).
But for normal riding where you dont want to get out of control, my experience is you will be fine with the kite depowered somewhat (compared to other "old" boards), all the time.
Especially because when carving downwind, you go a lot more with the wind than on other boards, so your apparent wind gets really low, thus you need even more depower for the kite to fly around in the carve, without backstalling.
If you are relatively new into foiling, you might also carve in really wide arcs, as tight carves comes later - thus with wide arcs you need even more depower, for the kite to fly.
So much it can often be difficult to keep it turning, and it might end in the drink when learning to carve the first times
slowboat is right, backstall "level" is a personal preference, all my kites will backstall if I pull the bar all the way in, also when powered on a surfboard or other board - thats how I like the trim.
Others want their kites to behave so they just pull the bar fully for max power, without risking collapsing or backstalling kites, personal preferences only
