CTS CHASSIS
ADVANCED VERSION

Based on the original CTS Chassis,

the Advanced Version is designed for experienced builders who want to create their own short-wheelbase setup.

With upgraded metal drivetrain components and a modular chassis supporting 242 mm, 252 mm, and 267 mm wheelbases,

it provides a high-spec foundation for builds using your own body, wheels, tires, and electronics.

tws-cts-advanced-ver-top-view-267mm

● The TWS CTS Advanced chassis is designed for real trail driving, with a front-mounted motor layout inspired by full-scale 4WD vehicles.
● Power is delivered through a planetary reduction gearbox and transfer case to the front and rear solid axles. Metal drivetrain gears provide enhanced durability and reliable power delivery.
● The steering system uses AMS (SOA) as the standard configuration, providing a simple and direct steering setup with room for further customization.
● Final drive ratios from 40:1 to 62.5:1 can be configured to suit different motor speeds and driving styles, with 50:1 as the standard setup.

Positive Caster Geometry

Positive caster improves straight-line stability and helps maintain predictable steering response over uneven terrain.

Large Kingpin Inclination

A larger kingpin inclination reduces steering load and minimizes unwanted chassis movement during steering, improving stability and steering control.

tws-cts-advanced-ver-top-view-267mm

The tws CTS chassis is designed specifically for off-road terrains. The front motor placement follows the same configuration as full-scale vehicles. Torque is increased through a planetary gear reduction box and then delivered to the front and rear axles via a transfer box. The robust bevel gears in the axles ensure durability and instant power output. The steering system uses AMS (SOA), an advanced setup that supports further modifications. The final transmission ratio ranges from 40 to 62.5 (default 50), which, when paired with higher-speed motors, provides excellent throttle controllability.
