Xolé Broken Arrow Quadcopter

thingiverse

This quadcopter's development was extensive and now its STL files are being released for you to follow a build log here: http://www.rcgroups.com/forums/showthread.php?t=2052857. The arms can be customized in size but should not exceed 330mm; this quad was designed for extreme acrobatics. It's exceptionally lightweight and rigid, using 7.5mm carbon tubes or arrow shafts for the arms. Replacing broken arms is easy, just loosen two screws and slide it out. The "blue wonder" motors or their hobby king equivalents can be accommodated without a silly mounting bracket. Also, it doesn't use a set screw that damages the bearing tube. Extensive thought went into this design; it'll impress you! Avoid over-tightening screws as they're meant to give in crashes while staying straight. Use recommended materials like Taulmans t-glase or 645 nylon, and Stratum3D 12-64 nylon. Don't opt for KK2; a flip32 FC is suitable. Watch this video: https://www.youtube.com/watch?v=-eQ6iR_dP9w.
