Aircraft
After being cleared for takeoff the aircraft moved about 1;000 feet down the runway and we received a 'Configuration' warning and had to abort the takeoff. We then taxied back to the FBO without further incident. Detected via Master Warning. The Lear 75 has an ongoing bulletin regarding an indication of un-commanded rudder trim movement. Until now I have not seen the trim move enough to exceed takeoff limits. On the takeoff roll the rudder indication went from '0' to 'L2' which is out of configuration for takeoff. This caused a 'Configuration' warning due to 'Take Off Trim.' System should be investigated for solution. This could be very dangerous on a contaminated runway.
Reporter indicated that this was an indication problem that resulted in a configuration warning. There was no swerve during the takeoff roll. The referenced bulletin states that Learjet is working on the problem and it should be considered a nuisance unless it exceeds 2 units of trim.
Learjet 75 Captain reported configuration warning during takeoff roll due to a rudder trim indication anomaly.
