Can I make a suggestion? I think many people could use it.
Your flaps are awesome, but it's still difficult to make realistic or, more importantly aesthetic aircraft with swept wings because flaps on airliners are angled.
While theoretically we could use the rotate tool, that wouldn't change the hinge axis.
So here's my proposal:
Make another two slotted flap, same scale, but this time, the trailing slat should be split in half diagonally so that there is no continuation of it to carry over to the next flap.
Next, add a single slot FAT-455 colored flap, also at an angle, to make a set of angles.
For the other single-slots, just add angled ones.
Don't mean to be pushy, and I know it seems like a lot, but it would be sooo helpful.
(P.S.: Could you consider expanding the FAT-455 family?)
EDIT: I know that the whole wing is usually at an angle. My issue is with a smooth seam between flaps and ailerons
