Scaleauto vs SCX

[Piesang]

Hi everyone. I'm new to this slot car racing.

I have a question for the clever guys on here.

What is the difference between a Scaleauto 18000rpm (12v) motor and a SCX 42b motor also running at 18000rpm (12v)?

I don't have a Pic of the 42b unfortunately.

Will there be any performance differences seeing that those 2 specs are the same?

Without looking at the specs I’d suggest that the torque rating of the scale auto motor would be higher than the 42B.

There's a few differences in the real world.

SCX motors are notoriously slow to get going, the guys who run these at our club would run the motor for a minute to warm it up before the race.

Also SCX motors can comfortably be geared 2:1 and not lose brakes whereas the Scaleauto would typically be geared about 2.8:1

The Scaleauto motor would be the racers choice, the SCX is much smoother.
