Helicopters breaking after pulling G’s?

Gianlc

O was flying today for the first time with the Cobra. After a few weapon runs, the helicopter started doing some weird noises and shaking. After a few more, the engine went out, without any damage in the UI. Did this got implemented on the MOD, so that helicopters break if you go past their limits, or this was a feature from Arma that I never noticed?

Yes, excessive g-forces will cause damage in Advanced Flight Model.

It was an Arma mechanic already?

This is a typical description of transmission (drivetrain) failure. Apart from the audible cues you have already noticed, there are also visual cues on GUI to warn a pilot he is damaging the transmission. This is the default, simple BI system that can be found in helicopters.
