About this item

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!

Be sure to check out all our 3.5" frames, as well as the rest of our Ummagawd selection!

    This frame is crazy durable. Had a bad crash yesterday that sheered off the bolts holding one of the motors and my ESC is now fried but the arm that slammed into the ground has no cracks/breaks. The frame lives on! Definitely recommended.

    Very nice little frame. Very easy to put together. The rear mounting holes are 20x20 and 25x25. Havent flown it yet. But the top plate fits a 4s 850mah GNB and a hero session 5.
