What should have been 5 minutes of work turned into 2 hours! While attaching the control stick brackets (CF-BKT-009-X-C-) per sheet E6 of the manual, a mandrel broke off a rivet in a hard-to-reach location. It took me over an hour to remove it. First I tried drilling it out from the rear, and found that was nearly impossible. I switched to using a Dremel with a small grinding wheel to grind away the rivet face, until enough of the rivet was gone so that I could push it through as if I had drilled it out; that wound up working. All that grinding damaged the foam, so I had to replace the pieces and replace them.
