Yet another wing

thingiverse

This is my second wing, and it even flies! Check out this video of its looping maneuver (not quite round but impressive for a beginner): http://youtu.be/XIrR3X5ENus. My friend also made a video showcasing the printing process of the plane's parts and the preparation for flight, set to beautiful music that makes it feel like the plane is weightless in the sky: http://www.youtube.com/watch?v=ut_Ei22on58. This wing has improved structural design with straight middle sections allowing carbon tubes to pass through, increasing strength in those areas. The maximum bending moment is now affected by the outside sections where bending moment is less. I've designed new wing sections for critical points, featuring a structural infill that makes them stronger and lightweight. With a wingspan of 1600 mm, this second wing is 50 mm wider than my first wing (http://www.thingiverse.com/thing:86982). A year after completing my big aerobatic wing plane (http://www.thingiverse.com/thing:407766 and http://www.thingiverse.com/thing:453090), I've perfected the building method for this wing. Simply print the desired wing sections sizes and wingtips, along with 1x 8/6 mm (outer/inner diameter) x 1000 mm long, 1x 8/6 mm (outer/inner diameter) x 307 mm long, 1x 4/3 mm (outer/inner diameter) x 1000 mm long, and 2x 4/3 mm (outer/inner diameter) x 297 mm long carbon tubes for assembly.
