H-Frame Quad Copter

thingiverse

To avoid landing gear, motor and props appearing in my photos, I opted for an upgrade to a h-frame design based on Home Depot towel bars. This frame requires two 15.5mm square 18in bars and one 30 inch bar, cut into halves. The center bars are the 30in ones, while 18in bars serve as motor mounts. Top plates attach to bottom plates using 3mm or 4mm bolts; nuts are placed on the bottom.
