These are racer oriented kits, so don't expect the manual to go into detail about every little facet of the build process. It is designed for the racer who already has experience with kit building.
Also, I wouldn't get too bent out of shape about a few minor hardware parts missing. Just email them. But if Kyosho ignores your complaint, then that is a legitimate problem.
However, as it stands now, there's no need to be "humiliated".
Let us know how it goes.
