However, he's also making a loop with his hand which shouldn't be there, IMO.
Look at the videos I posted. Safin, Fed, Djoko, Almagro, Monfils. They all take the racquet back and the elbow is leading. This happens automatically if you hold both hands on the racquet and don't lead with the head of the racquet by cocking back your wrist during the takeback.
The flying elbow is when you lead with the elbow, separate your hands and keep the racquet head in front of your hand a la sampras. that's different. just leading back w/ the elbow is not a 'flying elbow'.
