Competition-Level Chassis - Superior Handling & Flickability

The MST RMX 4 S PRO takes RWD drifting to the next level with adjustable wheelbase options, precision chassis tuning, advanced steering geometry, and quick-release service features. Paired with a highly detailed MTRTR clear body, it delivers the performance, adjustability, and scale realism needed to build an impressive drift machine.


Adjustable Wheelbase

The RMX 4 S PRO offers three wheelbase settings—257, 266, and 275mm — making it compatible with a wide range of 1/10 scale drift bodies. Its torsion-type dual vertical deck chassis balances longitudinal rigidity with controlled lateral flex for predictable, responsive drifting. The adjustable layout lets drivers fine-tune chassis balance to suit different driving styles and track conditions. This versatility makes the RMX 4 S PRO an excellent foundation for both beginners and experienced drift enthusiasts.

Tuned Performance

Engineered for serious RWD drift performance, the chassis features an anti-torque 4-gear transmission that can convert to a 3-gear layout, plus three motor positions for precise weight distribution and center-of-gravity tuning. The ATK V3 knuckles, adjustable Ackermann, 3° caster, and large steering angles deliver fast response and impressive drift control. The motor placement can be optimized around the rear axle to improve balance and handling characteristics. Together, these adjustments provide the control needed for smooth, consistent, and aggressive drift lines.

Easy Tuning & Maintenance

The innovative subframe and quick-release gearbox make suspension removal, maintenance, and differential access quick and convenient. Bullhorn-style shock towers provide highly adjustable shock angles, while the floating servo mount, quick-release battery mount, and fiberglass-reinforced nylon components improve serviceability, rigidity, and overall chassis balance. High- and low-CG ESC mounting options give drivers even more flexibility when tuning the chassis. Premium TR56 aluminum threaded shocks further enhance suspension tuning and performance.

Scale MTRTR Body

The included clear MTRTR 1/10 drift body combines sleek, performance-inspired styling with impressive scale detail. Its polycarbonate construction is durable and paint-ready, while included mirrors, grille pieces, accessories, and detailed decals let you create a highly realistic custom drift build.
