Description

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!

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

Ummagwad frame

"The screws mounting the arms and lower frame together are way to tight going through frame. And they are tuff to line up"

Amazing frame

"Have not been able to fly yet, the skystars mini stack very barely fits so needed to double sided tape the vtx on. Otherwise feels very sturdy."

— Casey A. (5/5)

Tough. Tiny.

"My smallest (non-whoop) quad to date and the build is going well. Plenty of space in the frame for whatever you want to run, Easy assembly and it feels tight. Can't wait to run it and tune it up!"

Best frame ever

"This is the most durable frame. It was the easiest frame to build with. I love this. I’ll be using this for any more 3.5 inch builds. It’s so durable that I ran it straight into a tree on my first flight and only a scratch"

— Owen W. (5/5)
