Can you increase the Overspeed margin?

I’m modifying an aircraft and I’ve set the max_indicated_speed to 175Kts.

When flight testing it, I rapidly descended and accelerated to 178-180Kts. The caused me to get the ‘You Crashed’ screen due to ‘aircraft stress’. That is a ridiculously small margin between Vmo and aircraft breakup.

I want to be able to ‘overspeed’ more before ‘crashing’ both from a realism perspective and a useability/fun perspective. I can’t just increase max_indicated_speed, because that would cause the red line/barber pole to be incorrect on the G1000.

Is there any way to increase this margin (without changing max_indicated_speed), even slighty to ~185Kts before getting the ‘You crashed’ screen?
