This is a replacement rear motor mount for a v-tail using two 1/2 inch booms in the back. The frame is the batbones from flitetest.com, but will also work with the anycopter variants. I printed with 5 perimeters, 200 microns, 50% infill with PLA. you'd probably be better off using ABS as it's less brittle, but it will just be another breaking point to save the motors if I crash hard again :)
