TRX Composite Slide Carburetor
The TRX 3.3 is equipped with same high-performance slide carburetor that has reliably powered a generation of TRX Racing Engines. The slide type carburetor provides less restrictive, straight through airflow for more power and improved throttle response. Because it is molded, Traxxas engineers incorporated superior internal design enhancements and precision not possible with traditional machined carburetor. The composite material does not transfer heat like aluminum for more consistent tuning.
