Armstrong web site (and all the videos Armie makes) say all the screws are titanium and the A+ system has specific barrel nuts. I'm sure you could substitute stainless for the screws. Not sure where you'd get the barrel nuts except from Armstrong. I guess you only need the barrel nuts if you want the A+ rigidity.
Either way, there's too many. You can't dismantle the foil without undoing the fuselage screws and the tail screws. (5 screws including 2 barrel nuts) Another 3 screws if you want to take off the front wing, and 4 for the plate mount. 12 screws in total for a full dismantle. Leave the front wing attached if all you want is a flat package.
Other brands get away with 4 screws total, certainly 2 to change foil wings and tails.
It sort of makes sense having all this ultra rigid stuff with titanium and all the rest if you're pushing the boundaries of performance. The vast majority of people are mowing the lawn and having a bit of a giggle. The really good guys are doing great stuff on any brand of foil.
Try reading more carefully, the screws are 316 stainless. The footstrap washers, mast base t-nuts and mast base washers are titanium, but all the screws are plain stainless M6, readily available, and can be substituted by cheap alternatives in an emergency.
I take the front wing off but leave the mast, fuse and stabiliser attached to the board, so that's two screws. I would remove the mast base from the board if I didn't have a van, so that's another 4 screws. But how is that any different from any other setup?
The advantage Armstrong has over almost all of the other setups is no aluminium, so lighter weight and no galvanic corrosion. Having come from Slingshot, and gone from a 6.7 kg foil setup that had to be disassembled and smeared with Tefgel every month or so, to a 3.5 kg Armstrong that could be left assembled for the whole summer, I'd suggest that maybe you have the wrong priorities.
