That’s my understanding as well.It has four wheels instead of three, which makes it no longer able to fall under DOT "motorcycle" rules on the road... which IIRC means it would have to meet the much more difficult DOT "car" rules. I was told that a three wheeler can sidestep a lot of the more burdensome safety regulations of a "car".
As mentioned earlier, I am not aware of a proven helicopter that has a rotor that folds at mid-span. It there one?There is nothing actually groundbreaking about this design, nothing untried just different disciplines coming together to optimise a design.
Yes, a toy that will require a license to operate.It is a toy
Thanks.Not a helicopter but the skycycle did exactly that....https://en.wikipedia.org/wiki/Butterfly_Super_Sky_Cycle
