The sound you've attached is a the stick shaker sound which indicates that you are below the flight safety envelope for speed, and you are/will stall the aircraft.Make sure that you have the correct saftey speed for take off.In other words, you are flying too low a speed to maintain lift on your aircraft.Tom
