Miniflyer - are you sure about 20 g at 120 mph and 500 foot radius? Looks like a decimal place slipped.
I'm pretty sure. 120mph are about 200kmph, which is 55meters/second. G's are velocity (in m/s) squared divided by radius (in meters). So radius is velocity squared divided by G's.
55^2 /20 gives me 151,25 meters radius. A bit more than 3 feet per meter, so this is close to 500ft.

What am I doing wrong then :
120 mph = 176 fps (based on 1mph = 1.467 fps)
A = v*v/r
= 176 * 176 / 500
= 61.952
since 1 G = approx 32 fps, 61.952 / 32 = 1.9 G
