Very clever people.
Is that an FAA registration number on the side?
I think they would do better to have either "Inspire like rising/lowering arms" or extending undercarriage.
I don't like the "tyres sliding across the ground" idea, especially when converting to wheeled transport, I think there'd be a tendency to peel the tyres off their rims.
A probably minor point but they are going to have to be careful about dust etc. sealing the various pivots and motors. Currently it looks like the wheel/prop motors are open and I can't help but wonder about sand/dust getting in and jamming a motor.
PS..... I want one lol.
