Built with precision and adaptability in mind, this chassis system delivers professional-grade control and customization. Every component has been designed for maximum adjustability, balance, and reliability, ensuring a smooth and responsive driving experience on any surface. Whether for casual drifting or competitive use, the RMX 4 S Pro sets a higher benchmark in performance and tuning flexibility.\u003c\/p\u003e\n\u003ch3\u003eAbout the RMX 4 S Pro\u003c\/h3\u003e\n\u003cbr\u003e\n\u003ch4\u003eChassis Design \u0026amp; Construction\u003c\/h4\u003e\n\u003cp\u003eThe RMX 4 S Pro's chassis is built around a Torsion-Type Dual Vertical Deck Layout, delivering exceptional rigidity and controlled flexibility for precise handling. The glass fiber reinforced nylon components ensure lightweight strength without sacrificing durability. Adjustable wheelbase options include 257, 266, and 275-millimeters, making it compatible with a wide range of body shells. The floating servo mount design eliminates interference between servo movement and chassis flex, while a lightweight quick-release battery mount supports both standard and low-profile shorty LiPos, allowing for fast swaps and optimal weight placement. Together, these innovations make the chassis both practical and performance-oriented.\u003c\/p\u003e\n\u003ch4\u003eDrivetrain \u0026amp; Power Delivery\u003c\/h4\u003e\n\u003cp\u003eAt the heart of the RMX 4 S Pro is an Anti-Torque 4-Gear Transmission, designed for smooth, consistent torque delivery and effortless drift initiation. This setup can be converted to a three-gear configuration for drivers who prefer a torque-positive layout. The gear differential is included as standard, providing a balanced blend of traction and slip for controllable, progressive power transfer. The triple-level adjustable motor position allows fine-tuning of the car's center of gravity, complemented by an ESC mount that supports both high and low center-of-gravity (CG) setups. These features give the RMX 4 S Pro unmatched adaptability for any driving style.\u003c\/p\u003e\n\u003ch4\u003eSuspension \u0026amp; Steering Performance\u003c\/h4\u003e\n\u003cp\u003eMST equipped the RMX 4 S Pro with an advanced suspension system that enhances stability, precision, and responsiveness. The short rear suspension arms improve lateral weight transfer, optimizing drift control. Bullhorn-style shock towers allow for a wide range of adjustable shock angles, while TR56 aluminum oil dampers and progressive DK short springs ensure consistent damping performance. The ATK V3 Knuckle Set offers zero trail and wide steering angles for aggressive drift entries, supported by a steering arm system with fine Ackermann adjustment and a built-in 3° caster angle to reduce steering pump.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"product-page-features\"\u003e\n\u003cli\u003eAdjustable wheelbase options for versatile body compatibility\u003c\/li\u003e\n\u003cli\u003eInnovative subframe design allows quick and easy removal of rear suspension\u003c\/li\u003e\n\u003cli\u003eAnti-Torque 4-gear transmission for smooth and consistent drift performance\u003c\/li\u003e\n\u003cli\u003eGear differential included for balanced traction and controlled slip\u003c\/li\u003e\n\u003cli\u003eTriple-level adjustable motor position for precise chassis balance and CG tuning\u003c\/li\u003e\n\u003cli\u003eFloating servo mount design prevents interference with chassis flex\u003c\/li\u003e\n\u003cli\u003eBullhorn-style shock towers enable adjustable shock angles\u003c\/li\u003e\n\u003cli\u003eTR56 aluminum oil dampers provide reliable damping and smooth response\u003c\/li\u003e\n\u003cli\u003eATK V3 knuckles optimized for wide steering angles\u003c\/li\u003e\n\u003cli\u003eGlass fiber reinforced nylon components maintain lightweight strength and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"_description-right\"\u003e\n\u003ch3\u003eIncludes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) RMX 4 S Pro 1\/10 RWD Electric Drift Car Kit\u003c\/li\u003e\n\u003cli\u003e(1) Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNeeded To Complete:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) 2+ Channel Transmitter\/Receiver System\u003c\/li\u003e\n\u003cli\u003e(1) 1\/10 ESC and Motor\u003c\/li\u003e\n\u003cli\u003e(1) Drift Gyro\u003c\/li\u003e\n\u003cli\u003e(1) 2S LiPo or 6-Cell NiMH Battery Pack\u003c\/li\u003e\n\u003cli\u003e(1) Compatible Battery Charger\u003c\/li\u003e\n\u003cli\u003e(1) 1\/10 Polycarbonate Body\u003c\/li\u003e\n\u003cli\u003e(4) Drift Wheels and Tires\u003c\/li\u003e\n\u003cli\u003ePolycarbonate Paint for Body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eScale\u003c\/th\u003e\n\u003ctd\u003e1:10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrive\u003c\/th\u003e\n\u003ctd\u003e2WD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\n\u003ctd\u003e2S LiPo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWheelbase\u003c\/th\u003e\n\u003ctd\u003e10.12\/10.47\/10.83in (257\/266\/275mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAssembly Level\u003c\/th\u003e\n\u003ctd\u003eKit*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp class=\"spec-fine-print\"\u003e*Tech Note: RC Kits are an unassembled Remote Control Model that require assembly, racer selected electronics, and other racer provided items.
