The Stampede 4X4 VXL turns extreme power into unbelievable monster truck fun! Traxxas Stability Management allows arrow-straight acceleration on slippery surfaces without loss of control. TSM also makes high speed cornering corrections in the background for you, without unexpected side effects. The Velineon brushless system and included 8.4V NiMH battery combine to unleash 35+mph. Install a 3S LiPo pack, and Stampede 4X4 shatters the speedometer with 60+mph speed! Stampede 4X4 is built Traxxas tough with a shaft-driven 4WD system and modular design of the Slash 4X4. A single center driveshaft connects the front and rear drive assemblies for maximum power transfer. The modular design allows the entire front or rear section to be removed with just a few screws. Stampede’s ground clearance increases off-road versatility, allowing you to tackle rough terrain and obstacles. Waterproof electronics allow Stampede to conquer wet and muddy trails with no regard for the weather. The Velineon VXL-3s ESC works with the 3500 motor for extreme power, smooth starts, and precise control while its brushless design reduces wear and friction. The VXL-3s offers 3 driving modes: Sport, Race, and Training Mode. Training Mode limits power to 50% to allow new drivers to gain experience. Velineon accepts standard 7-cell NiMH batteries up to 3s 11.1V LiPos with its integrated low-voltage protection. The TQi 2.4GHz transmitter is fully adjustable and can be equipped with a Bluetooth module that turns your Android, iPad iPhone or iPod touch (sold separately) into a powerful tuning tool. Automatic model recognition instantly recalls your settings for up to 30 Traxxas Link-enabled models. A 4-amp DC fast charger is included to maximize runtime and minimize down time. The included NiMH charger uses a 12-Volt DC power outlet for universal high-output charging. Peak-detection circuitry makes sure the battery receives a full charge every time.
