Exotek F1ULTRA User manual

INTRODUCTION
Thank you for purchasing the Exotek Racing F1ULTRA race kit. This has been a passion project we’ve been
working on for many years and also our very first car kit release. After years of adding innovation to other
car kits we’ve figured it was time to release our own kit incorporating cutting edge patented chassis technology
with high quality components and features you’ve grown to expect from Exotek. Importantly we didn’t just
redesign a 1/12 chassis to be an F1 car, we have designed the F1ULTRA to be an F1 chassis from the ground
up. You will appreciate the details we have designed in to maximize rubber tire grip as well as add extra durability
that these very unique cars require.
We hope that the F1ULTRA brings you as much joy and success on track as it has brought us while testing
this kit over the years!
