"Comfort" in cockpits of BOB adversaries

[KG26_Alpha]

Interestingly from Two Seconds to Kill

Bader mentions the Spit wing "folding up",

I had also read about this when over stressing the aircraft due to the pilots having to be careful with the Spits in hard manoeuvres as they were able to go past the safe limits due to the control authority being very light on the stick less than 10lbs where as the Bf109 was more than 20lbs.

I hope someone will put those figures right for me but I'm going from memory.
