Introducing the Grinderino.

If you love your Demibot, but wish you had one that's juuuust a little smaller, your wishes have been granted!

When Botgrinder asked if we can make him a 3.5" frame, he said he wants something just as good as the Demibot but in a smaller package. It took a bit of adjustment, but I think we hit the mark. As for flight controllers, 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. We've provided motor mounting holes to fit our Ummagawd Aerolite 1605 3600kv motors, as well as a standard mounting pattern for any other motors you might like to run.

And if you were curious... Yes, this is less than 250g all up weight!

UPDATE: The Grinderino arms are now compatible with 9x9mm motor mounting!

You can find all the related parts in the Botgrinder Grinderino 3.5" Frame & Parts Collection.

    Great quality at a remarkable price
    Color: Navy Blue
    I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews. The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available. The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.

    keyboard and case is phenomenal, trackpad is borderline unfunctional
    Color: Black
    I bought this case, because of the keyboard and trackpad, i wanted to use my ipad more like a laptop. the keyboard is phenomenal and certaintly better than other cheap ipad keyboards i have tried, I can actually use this one without having to repeatedly slam or hard press certain keys and can actually have a flow of typing. additionally, everything else regarding the case itself is amazing. it isnt cumbersome or bulky and it is very easy to swap between ipad and laptop mode on the fly. the trackpad however is genuinely unusable. the sensitivity on the trackpad is horrid and I cannot figure out how to change it, and additionally, clicking using the trackpad is outright impossible. you try to left click, it registers as a right click, or you try to click and it instead snaps your cursor to the bottom of the screen instead. it is also impossible to use any gesture functions with the trackpad, even something as simple as scrolling up and down or left to right is impossible. it is outright impossible to have any kind of workflow using the trackpad. it is unfortunately just a lot easier to use the keyboard and touch screen! its a shame that the keyboard and case itself is very nice too, so I will now have to spend more money on a separate mouse, which is additionally ANOTHER item i will have to carry around, just to make what I already bought work the way I expected.
