|The name is the same, but the new T-Maxx is a very different truck from the one that youve seen everywhere since 1999. The big story is the T-Maxxs wider stance (its a full inch wider, thanks to new, longer arms) and its rear-exhaust, round-port TRX 2.5 engine and re-engineered EZ-Start system. According to Traxxas, the new engine pumps out 60 percent more power than the TRX Pro.IPS Crankshaft
IPS stands for ‘Integrated Pilot Shaft,’ which eliminates the need for a separate clutch pilot shaft; instead, the TRX 2.5s crank and pilot shaft are machined as one piece. This increases precision for a wobble-free clutch, and there’s no threaded-on pilot shaft to come loose.
Lightweight, offset-wristpin piston and knife-edged connecting rod with 1:1 bore to stroke ratio.
Trimming weight from an engines reciprocating parts is an instant power gainer, and according to Traxxas, the long-stroke design actually reduces friction by applying less side load to the piston as it cycles through the cylinder. The connecting rod is also knife-edged to reduce ‘windage’ and minimize the conrod’s effect on the flow of fuel and air through the crankcase.
Slide carburetor with molded body.
Plastic-body carbs arent as prone to retaining heat or being distorted when heated as aluminum carbs are, so your mixture settings stay put, and the incoming fuel/air mixture stays cooler as it enters the engine. The carb also features an integrated return spring and a stop for the low-speed mixture screw to protect the spraybar against over-tightening.
ALL-NEW EZ-START 2
Traxxas spent a lot of time bomb-proofing the TRX 2.5’s EZ-Start 2 electric starter. The hand-held starter unit now fully encloses the battery, and has sophisticated circuitry that regulates the glow plug voltage so you’ll never need a separate glow igniter. The unit is also equipped with a thermal shut-down feature to prevent overheating, and diagnostic LEDs indicate glow plug and drive-circuit status for no-guess starting. The hardware that actually cranks over the engine is new too; in addition to an overall beef-up, the new gear train features an elastomer ‘cush drive’ that protects the gears from kickback and overloading.
In addition to the new engine and wide-track suspension, the T-Maxx will include:
> Molded head cap to prevent rollovers from scarring the TRX 2.5s heatsink head.
> Larger-diameter drive shafts rated for high-horsepower.
> Thicker, 3mm aluminum chassis50% more rigid than the original.
> New, thicker 3.5mm turnbuckles.
> All-new six-color graphics in four color mixes.
