IQCenter Micro-H Quad
Designed by Washington and Lee IQ Center Director David Pfaff, this frame is meant to work with the Micro-H Quadcopter hardware described in http://www.rctutor.org/3d-printed-micro-h-quadcopter.html. Dave's modifications include landing gear, wider arm-ends to accommodate all four mounting screws for each motor, and standoffs for mounting the OpenPilot Revolution board using 25mm M3 size nylon machine screws.
