No, no concerns necessary about static of monofoiling. You just need law of lever forces to see, that a complete monofoil (board and foil) in comparison to a stabi foil can always be significant lighter than a stabi foil, as also PF said.
Not just because of cutting the fuse, but because, the strut goes more forward under the board, and the wing can be smaller and with a lower AR to reach the same takeoff and glide ratio, and this all means less lever, less forces.
But better discuss it here: http://kiteforum.com/viewtopic.php?f=19 ... e#p1032665
where I should have already writen about this.
Now its on omg to choose a solution, but especially for traveling I would not prefer an experimental fuselage that could break, just to save a few 100 gramms ...
Oh, and building an even 1,0 kg Monofoil will work for sure, I have already an old Horue strut with a broken fuselage here to test this one time. But when trying two of the about 1,2-1,3 kg HORUE foils, I never liked it to ride these "on eggs" just in mind, to not break them. Just check the HORUE videos, great stuff, but Phil never lands the H13/H14 hard, mostly not even lands it, but puts the foil a side and himself in the drink.
