Default RV-12 airspeed at 5000 rpm?

Thinking about going light sport. I see Van's shows the RV-12 75% cruise speed is 116 mph. But that is true air speed at 7500'.
What would the indicated airspeed be down low?

Say you are at 2000' with the rpm's at 5000. You look at the airspeed indicator:
what does it show? Somewhere around 100 mph INDICATED?

Just to be completely clear, I am not asking about true, calibrated, ground or any other speed that would just confuse things.

Thanks

Thanks John, just the info I was looking for.
Looks like the pants/fairing are good for 7 to 10 mph.
