Narrative:

We were cleared for takeoff and advised a helicopter on upwind was 'no factor.' after takeoff; at approximately 500 ft AGL I saw a robinson type helicopter at our 11:30 position and very close. I exclaimed 'oh; my god!' at that point I should have taken the aircraft for an evasive maneuver to the right as the captain had a very delayed response. I should have known better; my fault. I did not have the helicopter visually on the takeoff roll; but should have known this might happen. I feel that the controller assumed the helicopter would have been out of the way by the time we took off and it wasn't. I need to be more vigilant and ready to take evasive action as pilot not flying.the tower should be more conservative and I should be ready to just take the controls and take evasive action and face the consequences later; my bad.
