To be fair most 500's have fargo tanks which means you get 2.8 hours out of it !
5 adults in a jetbanger, if they are average size then forget about full fuel
Figures for htose comparing
206 avg wt approx 1900lbs max take off 3200lbs
500D avg wt approx 1600 lbs max take off 3000lbs
Please bear in mind these are weights of some of the machines I fly, yes you can strip them down by approx couple of hundred pounds.
At 3200lbs the jr does struggle, 500 doesnt at 3000lbs as SF says both have the same engine using the same 5 min power limit ( been a few years since flown a jr so could be wrong). Both will lift more if load on a hook, but at max external gross both will struggle !
