Keep us posted as to what you actually receive. A 3 or 4 valve block, lights controlled via TX or switch on excavator, and spring loaded idlers. I was told I was ordering a 1.5 but then was confused as to why I had a 3 valve block, was then told the time frame that I ordered mine (Late March) they were upgrading to the "new" 3 valve block but no mention of a version 2.0.
