If I had to guess, I would assume he was refering to some of the things I've seen Jason Krause (and others) do where, in between tic-tocs, he manipulates pitch and inertia to make the helicopter appear (for ever so brief a period) as though it could sit there sideways or nose-up for as long as he pleases.

Just like the rabbit in a hat, however, it's an illusion.

Just a though.
