HPI Racing - RS4 Sport 3 Creator Edition - Chassis HP118000

1:10 R/C RS4 Sport 3 Creator Edition

Build Your On-Road Legend with the RS4 Sport 3 Creator Edition

The RS4 Sport 3 Creator Edition is the first HPI Racing car to deliver a completely built, ready to drive chassis, ready for you to add your own choice of body, wheels, tires, and electronics! This is the purest form of on-road RC that is waiting only for YOUR finishing touches to make it into whatever you can dream: muscle car, drifter, street car, sports racer or even a rally car!

No matter what kind of on-road action you prefer, you can be on the road and driving in record time!

Start with the Ideal Touring Car Chassis

The RS4 Sport 3 chassis is the latest evolution of HPI Racing on-road design.

It features a completely sealed and highly efficient ball bearing-supported shaft drivetrain for maximum efficiency combined with reduced maintenance. The suspension design is taken straight from scale and full-size racing technology, with a double wishbone suspension fitted with oil-filled coil-over shock absorbers.

The fully sealed drivetrain means there are no exposed gears, belts or drivetrain parts to get stuck with rocks or dirt, and the durable suspension design allows you to tune the car for all types of driving conditions, from club racing to drifting. This is a fully-featured, ready-for-anything car!

One Piece Molded Chassis

The main chassis is formed from a single piece of reinforced plastic and features the drivetrain tunnel molded right down the middle, just like a real car. It's a step beyond any plastic tub chassis car available today.

Low Profile Layout Design

One of the ways we gave the RS4 Sport 3 the best possible handling was to make sure all the components fit as low as possible in the chassis. This gives the car an amazingly low center of gravity for enhanced cornering capabilities.

Full-Time Four-Wheel Drive

The RS4 Sport 3 features full-time four-wheel drive to give you the most control and precision on the road or track. All four wheels are driven by heavy duty gear differentials at the front and rear, just like a real car. The extra traction gives you increased acceleration and cornering control for maximum confidence and fun.

Sealed Shaft Drivetrain

The drivetrain of all the RS4 Sport 3 models features the motor mounted longitudinally in the molded chassis, next to the long driveshaft that goes down the center of the car. The entire drivetrain, including the central driveshaft and gear diffs, is completely sealed to prevent dirt, rocks and debris from damaging or binding the drivetrain. The driveshaft, diffs and axles spin on ball bearings to maximize drivetrain efficiency.

Bottom-access Driveshaft

The central driveshaft that connects the front and rear differentials is easily accessed from underneath the chassis. This allows the drivetrain to be completely sealed to protect it from rocks and debris no matter where you may want to drive your car.

Easy Access Differentials

Getting to the differentials for quick adjustments is a matter of removing just 4 screws - this allows you to pop out the diff and change the grease, check the gears or just give it a general service.

4-Gear Metal Diffs

Bevel gear differentials at each end of the car transfer power from the driveshaft to the dogbones and axles that drive each wheel. The all-metal construction allows the drivetrain to withstand powerful brushless motors for easy upgrading in the future. Rubber-sealed ball bearings support the differentials and each diff can be tuned independently by changing the diff grease.

Double-wishbone Fully Adjustable Suspension

The suspension of the RS4 Sport 3 uses the race-proven double-wishbone suspension design, similar to a full-scale modern race car. You’ll be able to control the anti-squat and anti-dive of the front and rear arms using the standard pivot blocks, and the option parts allow you to adjust the sweep and toe angles. You'll also be able to easily change the roll center front and rear with the racing-style vertical ballstud mounting on both the inner and outer camber link mounts. Multiple shock mounting positions provide a full range of shock suspension angle adjustment to suit different road conditions.

Oil-Filled Threaded Shocks

The RS4 Sport 3 is fitted with a set composite coilover-style oil-filled shocks, just like what you'd see on a real race car! The fully adjustable shocks are fully tunable to provide the optimum chassis performance on a wide variety of road surfaces. The ride height is quickly adjustable by using the threaded shock collars. Further tuning adjustments are also possible by changing the springs and shock oil weight.

Tough Front End Suspension

The RS4 Sport 3 front end uses the strong C-hub style suspension seen on the latest RC touring cars, with a vertical ball stud camber mount that lets you change the front end roll center – which is a critical racing adjustment that allows the RS4 Sport 3 Drift to be a step above other sport-level RC touring cars. The suspension arm also features multiple shock mounting holes for easy shock angle adjustment.

Tunable Rear Suspension

The rear hub is fitted with a vertical ball stud style adjustment that allows easy adjustment of the rear roll center. Moving the ball stud up or down with the optional spacers changes the traction characteristics of the rear end as the car goes through the turns. The suspension arm also features 3 different shock mounting holes for easy shock angle adjustment.

Double Bellcrank Steering

The performance tested adjustable double bell crank system provides optimum steering precision at all speeds. A metal drag link plate connects the cranks for extra durability, the additional drag link mounting positions also allows for Ackermann angle adjustments.

Rugged Spring-Loaded Servo Saver

The RS4 Sport 3 includes an adjustable multipiece cam-style servo saver, which protects the servo from crash damage. In the event of a crash or collision, the front wheels usually take a big portion of the blow and transmits the impact directly to the steering servo. The strong spring-loaded cam action of the servo saver is designed to absorb this force and protect the servo gears from the impact!

Aluminum Motor Mount

The cast aluminum cam-style motor mount holds the motor in place for a secure pinion/spur connection. Two screws hold the cam firmly in position on the mount, and cooling fins on the lateral support aid heat dissipation to keep the motor running as efficiently as possible.

Rear End Chassis Diffuser

The built-in rear-end chassis diffuser element smooths out the airflow underneath the chassis for maximum aero efficiency. (Body not included)

Adjustable Height Body Mounts

The adjustable height body mounts let you fit any 1/10 scale touring car body from HPI Racing on to the RS4 Sport 3 chassis. All you need to do is adjust the front and rear body mounts to allow the wheels and chassis elements to fit properly underneath the body. Body pins hold the mounts in place, and the multiple mounting hole positions allow you to fine-tune the exact body fitment.
