Actually, I have the same problem here. I cut the deck, then slide out the card to 90 degrees, but when I flick it over it either flips onto the deck or just sort of flops out of the deck to the floor.
I just gave up and I do it as a rising card (pick a card, spread cull, hot shot cut, make their card rise). The rising isn't impressive but it still looks nice if you make sure of the angles.
I can do FISM Aces though
