The Traxxas Nitro Rustler 2.5 is a 1/10-scale nitro-powered stadium racing truck. Power comes from the larger-than-usual TRX 2.5 Racing Engine™ and performance-tuned exhaust giving the Nitro Rustler a top speed (depending on terrain and other conditions) of approximately 47 mph (76 km/h), making the Nitro Rustler among the fastest vehicles in its class. Changing the clutch bell can push the truck past 50 mph (80 km/h). The engine is easily started with Traxxas’ onboard EZ-Start™ push-button electric starter.
