Swing out and back to the platform. Turn one hand as if you were going to turn around and come back to the platform. At the front end, make your half turn, and as your body comes round into the Seven to swing back the other way, let go of the bar and continue the turn, giving your legs to the catcher for a Legs Catch. The trick is basically a Half Turn Swing and a Half Turn to Legs rolled into one.
The trick can be performed Half-Time in which case the flyer needs to leave the platform with a Mixed Grip and turn immediately at the frontend. Alternatively, it can be performed Full-Time (with an extra swing beforehand) and this flyer can change their hand to a Mixed Grip after the first swing.
