Narrative:

At approximately XA00 pm I departed the glendale airport for the deer valley airport. After a few mins, I became momentarily disoriented and may have drifted south of camelback rd, which is the northern boundary of the 10000 ft surface sector of the phoenix class B airspace. In retrospect, I could have prevented the problem by relying on my directional gyro until I again had my destination airport (glendale) in sight.
