Welcome To The New Home Of OS3!

We manufacture Top-of-the-Line HO Controllers, Complete Ready-To-Run slot cars, Precision Motors, and replacement/upgrade parts for Pancake-Motored cars.


Introducing the TFX!

With the TFX, OS3 has reimagined the Pancake-Motored chassis with a modified design, incorporating some of the principal features of the Aurora Thunderjet and AFX chassis.  The result is a Truly Beautiful, Lightweight, Low Center of Gravity, Great Handling chassis that is Ready-to-Run (RTR) right out of the package.

Typhoon Motors

Our NEW 3-lam pancake motors are available in 5 different Ohm values.  They are well balanced with pole-to-pole precision and final value accuracy.  They are designed for the TFX but will fit any Pancake-Motored chassis.  

Currently only available in the TFX.  Individual sales, including Tornado dynamically balanced version



Pro Series Controllers

Our HO Scale electronic controllers run all types of cars.   They feature Adjustable Sensitivity, Brakes, Coast and Choke (Depending on version).  With our ergonomic handle, visible and accessible controls, paired with comprehensive instructions, it is the only controller you need.
