It is important to note that the Downstream Gap measurement is added to the last motor block
of all QuickStick HT motors in the transport system. This gap value is important when consid-
ering the motor blocks that a vehicle owns (see
is also used for determining when vehicles are considered to be at the end of a path or cleared
of a node boundary (such as a Terminus Node).

Motor Cogging

Any cogging between the QSHT motor and the magnet array is typically not an issue unless
there is a direct human interaction with the vehicle while it is being moved, in which case it
might be felt (see
