have male/female connectors for proper connection between wing links. working now on the wing end and the mid-part. next stage is the body shapes and servo powered gears. Update - 13.08.2013: Redownload the right flap file...the old one was damaged. Update - 12.08.2013: Added flaps with axis system. Wing parts for best results (lightweight and strong) should be printed with 0% infill and 8-12 top and bottom solid layers. 2-4 perimeters. layer height don't matter.
