Was looking at the pics (and the video), and really hate to be a killjoy over such super superb workmanship, but thought I might point something you just may have overlooked out.
It appears to me that the Compressor Relief Valve is incorrectly connected in the pic if that is your compressor that is mounted in the belley pan opposite the sidecar, and that Compressor Relief Valve is mounted about a full foot or more higher up (Attached by tubing perchance? Hard to tell w/ white tubing and a white background).
Info below from the 22014 Robot Inspection Form:
(Compressor Relief Valve – set to 125 psi, attached to (or through legal fittings not tube) comp. outlet port.<R87, R78-B>
If I am wrong, please accept my sincere apology. (Just thought better to know now than later at inspection time).
