One little bottle with two important jobs: improve electrical contact at the braid and reduce friction while improving current flow at the motor commutator.

Slick 7 Voodoo S7-404is a dual-purpose slot car racing fluid designed for use as bothcommutator drops and braid cleaner. Long popular with serious slot car racers, Voodoo is useful for routine maintenance, race preparation, and even a little race-day performance trick.

Commutator Drops

Applied sparingly to the motor commutator, Voodoo helps lubricate the brush-to-commutator interface and improve electrical contact.

This can be useful during motor testing, break-in, and race preparation. As with any commutator fluid,use only a small amount. More is not necessarily better.

Braid Cleaner & Conditioner

Voodoo can also be applied to slot car pickup braid to help clean contamination from the contact area and maintain good electrical contact between the braid and track rails.

A small drop on each braid is particularly convenient between heats when you don't want to perform a complete braid cleaning.

Jim's Racer Tip – A Little Speed Secret

Here's another reason racers have kept commutator drops in their pit boxes for decades.

Apply a small drop of Voodoo to the commutator of arunning brushed motorand you'll often hear the motor RPM increase immediately.

The initial effect comes from reducing friction at the brush-to-commutator interface while improving electrical contact. The increase is temporary because the fluid quickly evaporates or is thrown off the spinning commutator.

That short-lived effect can be useful inslot car drag racing and standing-start competition. Applying a small drop immediately before a run can provide a little extra help during the initial launch and acceleration.

It's not permanent horsepower—the effect is brief. That's precisely why timing the application matters.

Useful for Many Types of Slot Cars

Voodoo is particularly useful for racers maintaining traditional brushed slot car motors and conventional pickup braid. Keep it at the workbench or in your race box for quick maintenance and race preparation.

Jim's Racer Perspective

Voodoo does two particularly useful things at two critical electrical interfaces in a slot car:the braid-to-rail connection and the brush-to-commutator connection.

Keeping both working properly contributes to consistent electrical performance. And when you're looking for that little extra advantage at the starting line, experienced racers know there can be more to that tiny bottle than simply cleaning braid.

Use it sparingly. Keep it handy. And don't tell the guy in the next lane everything you know.
