About this 3D model

This is a replacement arm for the Storm Racing Drone which uses an EMAX 250 frame. My quad fell from a great height and broke its arm and I didn't want to wait for a new carbon arm to arrive. At the point it attaches to the body it is 10 mm thick, the same thickness as the 4mm carbon fiber arm and 6mm spacer. The depressions front and back are for LEDs, both sides so the arm can be used on either side of the quad.
