Printed 630mm Hex with FPV Tray
Simple to print medium sized hex. Arms are from home depot and are dirt cheap http://www.homedepot.com/p/Best-Value-Centura-24-in-Replacement-Towel-Bar-in-Polished-Chrome-E8500A-24/100388799?N=5yc1vZbz9qZ12kx
Everything needed can be printed or purchased at Home Depot (maybe others).
It flies very well, nice and stable and very predictable. The motor mounts need a bit of a redesign. They tend to snap right at the end of the arm.... but still better than ruining a motor.
Total AUW with battery (No FPV gear) = 1750 grams.
UPDATE I have uploaded a revised motor mount (v6) that is much tougher than the v5 mount.
Let me see those makes!
