It seems that the metal ring at the top of our Flyer has gotten loose.
Confirmed 100% to be that portion, as we removed the sled and could manipulate just the ring itself, it is shifting up and down and left to right slightly. Enough to present massive problems with tilting and running (any camera weight shifts backwards and forwards on tilts, and running just makes it bounce around)
It seems to be held into place with just 4 small metal shims that have been hammered into opposing sides
Could these have bent or gotten loose somehow? Outward appearances are nominal.
I can't see any other way to adjust this, and I can't see any real space that can be shimmed. Perhaps dabbing gorilla glue around the edges and praying it seeps in and expands?
