- trhway 6y agowith 57inch props - large beasts though so it would be a personal helicopter style suit (https://en.wikipedia.org/wiki/Martin_Jetpack https://en.wikipedia.org/wiki/Martin_Jetpack) not true jetpack - it makes 94kg thrust at 23kw, so 2 of them is enough with 60kg/7kwh battery making for 9 minutes of hover (though full discharge is truly bad for the batteries).
