Once again, Botgrinder and the Ummagawd team make another absolute banger of a frame. - Imagine a Demibot-level frame but in a smaller package!  This frame will fit a single board whoop-style AIO or a 20 x 20 stack. The rear of the frame provides plenty of space to fit a VTX of your choice, and just the same, the front will accommodate any camera. Now updated to fit both 9x9 & 12x12 motor mounts! And, despite its size, it's still under 250g all-up weight!
UPDATE: The Grinderino arms are now compatible with 9x9mm motor mounting!
