Sleeve with a built in block-guard? well, cool, umm... it's my first day here... and um... the thread was here when I got here... :chuckles:

specifically the integrated block-guard was what I thought was neat.

I got to thinking though... and let's assume that (any) sleeves are made out of a denser material (seems likely) than the rest of the motor... and they do not have the benefit of homogenous contact, like a solid motor... I wonder how this affects heat transfer and dissapation...
