Here's a picture of a plan for "Revolution" type kites.
I used these plans for my "Definitively NOT a Rev 1.5" (I guessed measurements from the other ones given), but that does not yet perform as I like... In the meantime I've seen another plan that had a little curve (from vertical spar top to leading edge wing tip) that is not in this plan... I'm modifying my Rev 1.5 now to see what that does. Stay tuned !
