Odd things from Japan reckons it will fly at 56 MPH, although google translate reckoned about 6! I’d trust someone who reads the language over a machine translator any day, but reckon on the realistic speed being somewhere between those two.
I have no idea what the legal situation would be here in the UK- presumably you’d need a pilot’s license of some sort to operate it and I’d guess the machine would need to be certified airworthy? Regardless, it would be great fun and relatively cheap at about 17,500 UK pounds.
If I’m reading the autotranslated FAQ right there’s a max weight of 90 kilos too but I reckon I could lose some weight if it meant I’d get to commute via helecopter!
