Falconius is on point- one of the main things to worry about is whether you've got so much weight sticking out at the end of boom that a force differential would cause the tube to snap, or when it comes to vibrations. Sails are light though, so not much of an issue.

For your craft, that shouldn't be an issue. Though I would like to know; when your sails are folded, there's two triangular areas between the arms and the main chassis. Is that supposed to be empty space? And where do the wings store, inside the main body? Or do they curl up within the wing arms?
