The IRRA™ BoD has decided that the current motor rules will remain in place
as is and are therefore removing the previous allowance for motor submissions from the IRRA™ rules. The BoD reserves
the right to reexamine this decision should it become necessary due to unforeseen circumstance beyond our control. It is BoD's
belief that the current motor rules have proven to be effective and that there is no need for additional approved motors at
this time.

All Pro Slot 4002 and 4002B motors used in IRRA competition
must have the new white-colored "tamperproof" motor seal in place from the refurbisher or Pro Slot for a motor
to be used in events using IRRA rules
If a manufacturer releases a modified or new version of a previously-approved IRRA motor without informing the IRRA
of such changes, the IRRA Board, at its discretion, may remove that motor from the list of motors approved for use in IRRA
competition. The IRRA also reserves the right to remove any previously-approved motor from the list of approved motors.
Any motors with changed specifications submitted for IRRA approval must carry a new part number. The IRRA reserves
the right to ask manufacturers for unique tags and/or can markings for identification purposes on motors submitted for inclusion
in the IRRA approved motors list.
