If you are pulling more than 75A on a 500 sized scale heli, you must be doing 3D with it

I generally use about 12-18A on my 500 sized UH-1N with peaks up to 25A. It probably weighs about 3.8kg / 8.4lbs, 1x 5000mAh 6s lipo, Savox 1300kV motor, Ice 75A ESC, 2x 465mm main blades, 1700rpm.

So a 75A ESC should have a safety factor of 3 or 4 if it is flown scale circuits.
