Narrative:

I was the captain on a flight from brl, ia, to stl, mo. This airport is uncontrolled and our company operates scheduled passenger service here. On taxi out of the gate, we completed our taxi checklist and called ZAU for an IFR clearance for takeoff. He was unable to give us an IFR clearance because a helicopter (uh-47) was on the field and had the IFR release from that airport. It was VFR so we decided to take off VFR, and pick up the IFR clearance in the air. We announced we were taking the active and proceeding sbound, and I had visual contact on the helicopter, who was midfield on the grass beside the runway. He announced he was taking off and then a left turn after takeoff. As I advanced the power for takeoff he began to rotate and proceeded straight ahead and paralleled the runway. I had visual contact on the helicopter the whole time, but after rotation, I banked right and quickly passed the helicopter off to his right side, VFR. There was never a conflict or did I feel I was jeopardizing safety, but I overtook the helicopter quickly and from an observer on the ground point of view, it would appear that my aircraft was close to the helicopter. 2 things that would have solved this, if the helicopter turned left after rotation, and I would have waited to see his left turn, before I advanced the power for takeoff.

Narrative: I WAS THE CAPT ON A FLT FROM BRL, IA, TO STL, MO. THIS ARPT IS UNCTLED AND OUR COMPANY OPERATES SCHEDULED PAX SVC HERE. ON TAXI OUT OF THE GATE, WE COMPLETED OUR TAXI CHKLIST AND CALLED ZAU FOR AN IFR CLRNC FOR TKOF. HE WAS UNABLE TO GIVE US AN IFR CLRNC BECAUSE A HELI (UH-47) WAS ON THE FIELD AND HAD THE IFR RELEASE FROM THAT ARPT. IT WAS VFR SO WE DECIDED TO TAKE OFF VFR, AND PICK UP THE IFR CLRNC IN THE AIR. WE ANNOUNCED WE WERE TAKING THE ACTIVE AND PROCEEDING SBOUND, AND I HAD VISUAL CONTACT ON THE HELI, WHO WAS MIDFIELD ON THE GRASS BESIDE THE RWY. HE ANNOUNCED HE WAS TAKING OFF AND THEN A L TURN AFTER TKOF. AS I ADVANCED THE PWR FOR TKOF HE BEGAN TO ROTATE AND PROCEEDED STRAIGHT AHEAD AND PARALLELED THE RWY. I HAD VISUAL CONTACT ON THE HELI THE WHOLE TIME, BUT AFTER ROTATION, I BANKED R AND QUICKLY PASSED THE HELI OFF TO HIS R SIDE, VFR. THERE WAS NEVER A CONFLICT OR DID I FEEL I WAS JEOPARDIZING SAFETY, BUT I OVERTOOK THE HELI QUICKLY AND FROM AN OBSERVER ON THE GND POINT OF VIEW, IT WOULD APPEAR THAT MY ACFT WAS CLOSE TO THE HELI. 2 THINGS THAT WOULD HAVE SOLVED THIS, IF THE HELI TURNED L AFTER ROTATION, AND I WOULD HAVE WAITED TO SEE HIS L TURN, BEFORE I ADVANCED THE PWR FOR TKOF.
