How do you control the chopper in GTA IV? I need to know all the controls of flying a chopper in GTA IV.?

I can't get through A Revenger's Tragedy in GTA IV. Some say it's easy while others have problems. For me it's the toughest mission mostly because it takes too long. When I get on the boat to chase Dimitri and jump on the chopper I almost immediately lose him and he always gets away! Once flying too high and not seeing where he went. Second time flew in and crashed into the buildings then was going low. The cutscene showed my chopper landing on the pad and there wasn't a propeller on it! I need the details of the controls in GTA IV for flying the Annihilator helicopter. Could someone please help? I've been trying to beat this mission for over 3 hours or more! ARRRRGH!! MOTHER F******!! As Nikko says....How do you control the chopper in GTA IV? I need to know all the controls of flying a chopper in GTA IV.?
