Full-size, fully printable tricopter

An afternoon-designed and printed tricopter, designed primarily for Dynam KA22-15M motors (though may fit others, or perhaps many more if you're not afraid of using a drill), a 'standard' 20x40mm servo and a 624 bearing for holding the tail motor (you RepRap builders should have a few of these left :-) )

Shown here mostly assembled, with 10x4.7 propellers attached.
