INTRODUCTION

Thank you for purchasing the new T-Maxx 3.3. This T-Maxx is our 
biggest and meanest Maxx ever, and we are confident it will reward you 
with many hours of exciting monster truck action.
We know you’re excited about getting your new T-Maxx 3.3 on the road, 
but it’s very important that you take some time to read through the 
Owners Manual. This manual contains all the necessary set-up, break-in, 
tuning, and operating procedures that allow you to unlock the incredible 
performance and adjustment potential that Traxxas engineers designed 
into T-Maxx 3.3. 

Even if you are an experienced R/C enthusiast, it’s 

important to read and follow the procedures in this manual. T-Maxx 3.3 
contains new technologies in the engine, suspension, and transmission 
operation that you may not be familiar with. Pay particular attention 
to the fuel and break-in requirements for the engine. 

The advanced 

design of the TRX 3.3 Racing Engine has a special break-in procedure 
that has been developed and proven to produce the best-performing 
engine possible. Using traditional or old-fashioned procedures could 
reduce engine performance and longevity.

T-Maxx 3.3 is made to be a complete package that starts with the 
highest level of engineering and is equipped stock with the most 
powerful Ready-To-Race® engine available. We want you to feel 
confident that you own the best-performing truck in the market 
and that it is backed by a team of professionals who aim to provide 
the highest level of factory support possible. T-Maxx 3.3 is about 
experiencing total performance and satisfaction, not just with your 
truck, but also with the company that stands behind it.

want you to enjoy your new T-Maxx 3.3!
