Make sure you are patched up to date. Wings do come off on the Albs (DIII's mostly but all do) tested it many times, and also more recently when Olham said he could not make them break. Think he reinstalled in the end..
Wing damage from diving isn't great in CFS3, but they do get damage when overspeed just takes too long usually. Mostly wing breaks will come from severe manoeuvring, pull ups after a dive. it will usually not be 1 dive and pull up but a few. DV's are slightly stronger (may take say 5 or 6 180 mph dives, DIII maybe 2 or 3). Again with the trillion settings and options, joystick settings etc etc, hard to make it work for everyone, but it definitely does do it.
