I have burned slipper pad because from factory it too loose and hpi recommand "Tighten set screw fully then loosen one half turn" after rebuildind I loosen 1/8 turn and all working good no more slipping clucth and wheelie all time and now did we think is better to loose slipper at minimun 1/4 turn for protect the drivetrain or 1/8 it ok ?
