I believe our own Deb C owns one of these, I am sure she will be along to contribute to this thread.

My gut feeling looking at the review video is that the body could have been made smaller, something like a Martin NY would have been right.

I actually designed a travel guitar many years ago (proper drawings and all) which had a detachable neck, (as opposed to folding) which fitted diagonally in the case. As I recollect, my design was way smaller than the Voyage-Air.

Maybe I will resuscitate it ...
