Narrative:

I was on the 45 degree departure leg from runway 20 sac, climbing through about 1300 ft. I just adjusted my pitch angle to cruise climb speed of 80 KTS and started a clearing turn to the left when I saw a white/red C152 at the 12:30 O'clock position and slightly low. I steepened my left turn to clear the other aircraft. Tower did not advise me of the other aircraft. Tower was very busy with several aircraft in the vicinity, and probably had his attention away from me and the other aircraft, which was on the approach leg to left downwind for runway 20.
