I really like that it switches off the outer pair of propellers in level flight, that's a nice feature.
Changing the vertical alignment of the wings to horizontal after takeoff is also really cool, an interesting alternative to 4 vertical propellers with a separate pair of wings. It seems to eliminate the extra moving parts to control those vertical propellers.
