Aircraft; Procedure
I was called for an ROC check flight on Aircraft X. I accepted the maintenance check and drove to the hangar to perform the ROC flight. Upon arriving to the hangar I briefed with the mechanic on what work was performed to the helicopter and what components were removed/replaced. I preflighted the helicopter while it was still in the hangar. During preflight I was aware that major maintenance was performed to the starflex and M/R (main rotor) assembly. I was unable to rotate the rotor system to inspect frequency adapters and chose to do so once aircraft was moved outside. For reasons unknown I did not climb back on top of the aircraft to check all 3 adapters.  I believe my desire to accomplish the task at hand and be of good help to the mechanics to possibly fly another aircraft may have factored into why I was time constrained. I understand that as an ROC pilot it is my duty to sign off the aircraft check flight for return to service and in doing so this requires my utmost attention to detail and vigilance during preflight regardless of time constraints or space constraints.  The final eyes on the aircraft are my own and I should check everything thoroughly and ignore everything else to include external pressures of my personal life. In the future moving forward I will take my time during preflight to inspect everything no matter how many personnel may have worked on the aircraft or however many QA checks were done. I will inspect everything as I was the one who did the maintenance and not let any external factors weigh in on my mental status as I am conducting ROC checks.
Pilot reported not rechecking main rotor components during preflight for a maintenance check flight after completion of maintenance.
