This is a kit card of a glider. It glides very well if weighted properly. I made this because I saw many kit card airplanes that did not fly and wanted to make one. It must be printed with a 0.05 mm layer height. If the glider nose dives then print out the light weight securer. If the airplane flips backward print out the heavy weight securer. (also make sure that the wings are slanted back to provide lift. If they are slanted forward then the fuselage sides need to swap)
Some recommendations for this print are.
