Hello,After startup, when I release the brake, the MD-11 begins to roll without any throttle. Actually, if I am not careful, it will taxi forward until I activate pushback. Is this correct or is it a throttle align problem?Thanks,Ron Sagel

Your suspicion should be correct. It takes extra energy to start the heavy rolling, then less to keep her going. Check that alignment.

With low weights the MD11 starts rolling without adding extra power

Ron,It shouldn't roll with no throttles. This is most probably a calibration issue with your throttle controls.Open the pedestal window, move your throttles all the way back and then press F1. If you see the throttle levers move further back, this means your throttle control axis needs calibration.
