I would say the rudder (and HS) tip is a pretty low priority area for inspection -- would recommend KISS unless there's some specific reason for it.
I did put my wingtips on with #6 screws /nutplates to keep options open w.r.t. wingtip antennae. Never did that but I do currently use one of the screws for a GOPRO mount
No, it's because the plans called for rivets and I didn't see a need to do otherwise.Randall did you have problems using screws on the rudder tip? Is that why you didn't use screws?
Do you not inspect the security of the counter-weight or the tip rib during the conformity inspections? Or check for corrosion in the bottom? How do you inspect those items?
