UPDATE: The Grinderino now has available 3.5″ or 5″ arm choice.

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.And, despite its size, it’s still under 250g all-up weight!
