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

COMING SOON!
