Great looking kit. I've studied the build manual, proffessional step by step drawings, I can see they have but some hours into this.

From what I see, the hydraulic tank is built-in to the rear frame. Is it a fully welded tank, or there are some gaskets?
you might have control of it, but anyway; it is suggested to use thread lock on all hydraulic niples, as Loctite 542. It's actually great that it comes in a kit form, then one can take the time to mount the hydraulics better than chineese assembly line workers, that usually are in a big hurry.
