The GT4 has a range of 300 miles on batteries alone. It also has a supercharged gasoline engine that runs a generator to produce electricity. Combined range is a 1000 miles, which seems to be decent for this class of aircraft. Volta Volare's website says you can reserve one for $9900. You will have come up with an additional $485,100 to actually purchase one. This is almost enough to make me get a pilot's license, assuming I won the lottery. I'd best go check my tickets...
