The amazing world of LEGO® Technic constructions.
Based on the vision from Ole Kirk Christiansen (1891-1958), a carpenter from Billund/Denmark, whose personal motto was "Only the best is good enough" - Leg Godt (Play Well).
TechnicBRICKs blog (TBs hereafter) is devoted to the LEGO Technic theme and intends to spot mainly on news and developments, rather than new sets reviews or users creations (aka MOCs). However you will also find them here occasionally...
This week, two nice videos from duku666, featuring his 'Devastator Tank' both in an hill landscape and forest.

I liked the tread design, it can be improved to build bigger models. But if they are turning on the wheels/tires instead of a gear mechanism, it's really ineffective.
Agreed, under heavy loads I would imagine they would slip.
Hmm... from the name and the colour scheme, I can imagine where the author got some inspiration... ;)
The idea for the tracks appears simple and expansible, both in length and width, albeit at a cost of requiring many parts. I'd like to try something like that some day!
It appears to suffer the same problem as my ill-fated Grabber 2: underpowered for its weight. From the videos, it seemed to struggle with the steep hill and loose terrain. Maybe replacing the M motors with their XL counterparts would help, at the cost of faster battery drain.
About the wheel-based tread sprockets: that's what I thought, too. But the biggest LEGO gear available, both iterations of turntable, has standard-sized teeth, which at this scale would probably slip anyway: that's why the new tread pieces use sprockets with much bigger teeth.
A solution would be to keep the tracks under tension (maybe that's exactly why the author included the smaller wheels on top) via some kind of suspension mechanism.
