As far as specs go the big max is 80mm long, 43mm around.

I agree, the Novaks aregeared toward the low-mid level trucks, and the pletty/nue are the high end...without question. As far as service work, I agree, its probably going to take longer to fix a pletty. But a motor in its voltage range and good bearings is going to last a looooong time. Im not knocking the nue in any way, by any means. As far as one size fits all, well...that can be debated for years.
