As many of you know, Steven here on OSE offers water cooled motor mounts that can offer outrunner cooling for our models.

Here are the ones he offers:
Etti 380 Size Water Cooled Motor Mount Can anyone provide dimensions for this item?
Adjustable 380 to 540 Size Water Cooled Motor Mount
Adjustable 380 Size Water Cooled Motor Mount
540XL Size Water Cooled Motor Mount: In Fiberglass and In Carbon

For most mini to large size models, these all work quite well. However, if we start talking about small, micro sized models, then I have found that some of the 380 size water cooling blocks won't fit, even without the upright pieces.

That being said, I'm wondering if anyone else is aware of a manufacturer that makes small water cooling blocks that allow for the shaft of the motor as well as mounting screws to pass through. I know that the original Renegade has one that Diegoboy owns and I'm thinking that this item didn't just appear out of thin air. Anyone have more information?

Thanks.
