HSFX 5 Spitfire Question

[KnightFandragon]

Soo, I know this mod has reliability and its possible to break your plane by putting to much stress on it but my question is why does the spitfire creak, eek, erk and squeak alot more then the US PLanes? I was flying the IXc LF 25Lb and I didnt hardly evne have to bank much and it would squeak and creak and the like. Does that mean im damaging my plane and will eventually break it if I keep doing it? I know higher speeds will make it do that more often but I was doing like 380ish and pulling up or banking or rolling just a bit. Does this plane just have a weak airframe then? Not a complaint, just wondering...how long can I keep that up on that plane before I break it?
