You're extremely right: IF!
I don't expect it will ever be produced, at least in nearest future. The only way is if somebody would like to invest in it. In any case you made me curious - I'll speak to our company chief pilot who is retired Kamov's test pilot and he told me that he has hover this device.
I'll post about the results.
Merry Christmas to all rotorheads and their families!
Cheers,
Alex
