After detaching the rudder and vertical stabilizer (hopefully for the last time before final assembly), I started to comply with SB 18-03-30. As previously mentioned, the elevators were at the high end of the required travel range (at 30˚ up, with the required range between 25˚-30˚), but at that position they weren't being stopped by the flanges of the horns, making compliance required:

I measured, and if only the elevator stop angles hadn't been filed down to give the full range, then the horns would still touch them at the flange, and the movement would only be down to 28˚ up, still within the allowed range, so I removed the elevator stop angle and replaced it with a new but equal (just unfiled) part:

I also opened up a bit of the rudder's leading edge to give room for the grounding strap without interfering with the attachment:

Finally, I 3D printed the template to adjust the elevator pushrods:

With this, the last steps on section 11 are now left for the final assembly at the airport.
