Birdbone Plus FPV Quadcopter Frame


Update (4/15/18):  File, "bb004v1.1 plus motor mount lower.stl" added after substantial testing.  This is a stronger version of the lower motor mount part.  The v1.0 part had a little too much flex.

The Birdbone Plus is a very fast, lightweight, rugged, 3d printable, plus configuration freestyle/race FPV quadcopter frame that can accommodate 4", 5", and 6" props.  It uses standard 8mm O.D. carbon tubing for arms.  Cut the tubes to length as-needed for your props.

I developed the frame using ABS and SemiFlex.  Other materials will likely work very well.  Typical weights for a 6" prop configuration are 75 grams for the printed components and tubes, and around 25 grams for all the mounting hardware.  Substitute nylon/aluminum/titanium mounting hardware to further reduce weight.
