SUP hydrofoil back wings

These are SUP/kite hydrofoil back wings. Hole spacing is 1.5" for M6 screws. Meant to be installed on a 2x2cm aluminum fuselage. One is touching the fuselage on both sides, and should be stiffer because of that. These are meant to be printed leading edge touching the build plate.

Edit 26/06/2021: Added two more biplane back wings. One is mh32 and the other naca0010 profiled. I like the latter better.
