System overview

Short version
For those who don’t want to read the manual, at first the two most important Don’t Forgets:
Secure the bearing screws with Loctite or 5-min epoxy (after a dry-fit test)! Otherwise they could
get loose and the bearing falls off.
Remove a piece of the white epoxy gap seal lip, to simplify inserting the pin into the flap horns.
