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.

Regards
Hank
