The Helicopter Card was one of Slydini's feature routines and is one of the most fascinating card routines of all time. A freely selected card mysteriously travels from the fan to the table, even though the spectator can check the cards on the table without finding his until the card invisibly flies like a helicopter to the table.
Dennis Barlotta, aka D. Angelo Ferri, studied for 8 years under Slydini. After several years of apprenticeship, Slydini was willing to teach Dennis this wonderful routine. Dennis will not only explain the mechanics and sleights but also the psychology, choreographed questions, and the patter and its delivery. If you have never been able to learn this routine from books, here is a wonderfully clear and detailed explanation of it in video form which will make it a lot easier to grasp the important points of the routine and not only understand how it works but also why.
Here is a partial performance Dennis did many years ago:
Here is Slydini himself performing it:
