Narrative:

Unable to contact ATC on ground to file IFR so elected to file airborne. However, ATC was too busy with other calls so continued to climb to 6500 ft. I kept monitoring ATC on 135.4 but was unable to make contact until after climbing through class C airspace, which is under the jurisdiction of ont socal departure. I was unable to climb fast enough to clear the class C airspace. I failed to recognize that takeoff to the west from flabob put me into class C as soon as I climbed through 2700 ft MSL. I file IFR on all flts. This flight was a rare exception. I guess that I failed to recognize that VFR flts in controled airspace shifts the responsibility from approach control to the PIC. The flight from vny to flabob was conducted with an IFR flight plan. I always try to go IFR because I like having radar surveillance especially in the los angeles basin.
