ROAR stator rule and announcement

March 25, 2015
ROAR has made a change to the spec motor rules. We would like to make our racers aware of this change. All motors that have been submitted up to this point for approval have satisfied this specification, despite it's absence in the rules.

This is a change to the minimum length of the stator, to align ROAR rules with other major sanctioning bodies. There was no current minimum.

Original language (8.5.4.2): "The overall stator length parallel to the motor shaft shall be a maximum 21.0 mm"

New language: "The overall stator length parallel to the motor shaft shall be minimum length 19.3mm, maximum 21.0mm"

Please remember despite approval, all motors are subject to pre race inspection to ensure legality.
