Narrative:
Departing smo, I announced '...taking active runway 21 for straight-out departure.' during my ground roll, a helicopter appeared on my right that was just breaking ground. Just then I heard the helicopter pilot (in a thick foreign accent) announce he was departing. We were not at risk of colliding since my speed was greater at that point and we were separated approximately 75 ft horizontal. (He was still over the taxiway.) the helicopter pilot then screamed at me for not announcing my departure and tried to blame me for his apparent lack of attention. I feel the situation could have been avoided had the other pilot been more aware of his surroundings. He departed midfield and seemed to be facing west the entire time. Another cessna landing at smo just after my departure heard the entire exchange, and confirmed that I had announced my intentions properly. I have this pilot's tail number. The helicopter pilot refused to supply his tail number to me after the incident.

Title: C210 PLT ANNOUNCES TKOF AND ROLLS, THEN SIGHTS A HELI LIFTING OFF AT MIDFIELD FROM THE TXWY WITH 75 FT SEPARATION.
Narrative: DEPARTING SMO, I ANNOUNCED '...TAKING ACTIVE RWY 21 FOR STRAIGHT-OUT DEP.' DURING MY GND ROLL, A HELI APPEARED ON MY R THAT WAS JUST BREAKING GND. JUST THEN I HEARD THE HELI PLT (IN A THICK FOREIGN ACCENT) ANNOUNCE HE WAS DEPARTING. WE WERE NOT AT RISK OF COLLIDING SINCE MY SPD WAS GREATER AT THAT POINT AND WE WERE SEPARATED APPROX 75 FT HORIZ. (HE WAS STILL OVER THE TXWY.) THE HELI PLT THEN SCREAMED AT ME FOR NOT ANNOUNCING MY DEP AND TRIED TO BLAME ME FOR HIS APPARENT LACK OF ATTN. I FEEL THE SIT COULD HAVE BEEN AVOIDED HAD THE OTHER PLT BEEN MORE AWARE OF HIS SURROUNDINGS. HE DEPARTED MIDFIELD AND SEEMED TO BE FACING W THE ENTIRE TIME. ANOTHER CESSNA LNDG AT SMO JUST AFTER MY DEP HEARD THE ENTIRE EXCHANGE, AND CONFIRMED THAT I HAD ANNOUNCED MY INTENTIONS PROPERLY. I HAVE THIS PLT'S TAIL NUMBER. THE HELI PLT REFUSED TO SUPPLY HIS TAIL NUMBER TO ME AFTER THE INCIDENT.
