Aircraft
I proceeded with a normal interior and exterior pre-flight check. This was the second leg of the day with no discrepancies noted on the first. After engine start I completed a trim op check and set the trim in the takeoff range. I did note that the indicator seemed to be much more trimmed up than usual. On the takeoff roll; with a bugged takeoff V1 speed of 103 KTS; VR 106 KTS; I began to attempt to rotate the aircraft with no avail. The forward pressure was very high; but I could distinguish that the elevator was not jammed. At this point speed was accelerating past 140 KTS and with heavy back pressure the nose lifted. At this point I was rapidly hand trimming the aircraft to full indicated nose up; but still showed heavy nose down response. Due to the indicator at its full nose up value; the trim would not go any further.I continued the climb; and continued working the problem.I then moved some PAX aft; and began to notice some slop in the actual trim wheel. While manipulating the wheel; I could see the 4 retaining set screws were coming loose; and the trim indicator was just 'flopping around.' At that point I manipulated the wheel and indicator to regain normal 'natural' trim feel; and by this point was at my destination; and made a normal landing. Upon inspection by maintenance personnel; it was noted that there was no Loctite on the setscrews; and the indicator was just occasionally catching.In review; I used approximately 5;600 feet of runway; with a computed accelerate stop of 3;690 feet. My rotate speed was in excess of 140 KTS with a computed VR of 106 KTS.
CE560 pilot reported it took heavy back pressure to rotate on takeoff; and later determined the set screws securing the trim indicator had come loose; affecting the stabilizer trim operation.
