TRX 2.5R Racing Engine

TRX 2.5R Racing Engine
$85.00

Replace your Pro.15 with a 2.5R for intense wheelie-popping power and eyeball-flattening acceleration. Put your Nitro Stampede into orbit! This is the engine that re-wrote the book on nitro engine performance. Before the 2.5R came along, high-performance engines were expensive, short-lived, and difficult to tune. With the TRX 2.5R, Traxxas out-performed expensive "racing" engines while delivering easy tuning, convenient starting, and long-term reliability never achieved before. Traxxas TRX engines set the standard for nitro power.

Simply plug in the hand-held control unit, push the button, and the EZ-Start system automatically heats the glow plug and the lightweight, compact on-board drive spins the engine. Traxxas' exclusive Smart Start™ technology monitors critical starting functions, automatically sensing and diagnosing potential problems for trouble-free engine starting every time.
