5.8 OHM RULE and Certain Chassis - PLEASE READ

It has been brought to my attention that some Life-Like “T” Chassis cars and the Mattel Battery Powered Race Sets with HPX2 Chassis cars have 3.3 Ohm or lower rated motors/armatures.  Although the chassis are legal to use in Racing to the Future™ events, the motor/armature are not legal would need to be replaced with a 5.8 Ohm or higher rated motor/armature.  Make sure to check your motor/armature’s Ohm rating.  You can see how to do that here:

Here are pictures of the chassis this applies to:

Life-Like “T” Chassis  The 3.3 Ohm motor and the 6.0 Ohm motor appear the same.  Make sure and measure.


Mattel HPX2 Chassis – The 3.3 Ohm Motor Wires can be green, gold or red.  Measure and make sure.
