RS4 SPORT 3
FEATURING THE ONE OF A KIND RTR-X!

ΠΕΡΙΛΑΜΒΑΝΟΝΤΑΙ ΚΑΙ STANDARD ΖΑΝΤΟΛΑΣΤΙΧΑ KAI DRIFT!

World Champion Drifter Vaughn Gittin Jr. and the Need for Speed crew teamed up to build this one-of-a-kind, fully-functional Street, Track and Drift machine, and this is the official, authorized RC replica, only from HPI! Balancing 5.0 liters of tire-shredding American horsepower with vintage American, Japanese, European and Drift culture inspired design influences, Vaughn has incorporated state-of-the-art technology while retaining a nostalgic feel into his vision for the 1969 Ford Mustang’s timeless body. The RTR-X was designed and built from the ground up to be driven hard; the RTR-X is NOT a trailer queen. While Vaughn will be the only one behind the wheel thrashing it, the entire world will be able to enjoy driving the HPI 1/10th scale RTR-X. The RS4 Sport 3 is a fun, easy to drive and simple to maintain street car, featuring a completely pre-assembled race car chassis for amazing fun and loads of action! We’ve packed in all the latest features like 2.4GHz control and complete waterproof protection! The chassis is factory assembled right out of the box, making the RS4 Sport 3 a quick and easy way to get straight into driving, racing and honing your skills! This is a complete racing machine that looks and drives just like the real thing!

PRE-MOUNTED DRIFT AND GRIP TIRES INCLUDED!

The RS4 Sport 3 1969 Ford Mustang RTR-X is fitted with a set of HPI Spec-Grip treaded rubber tires for maximum grip on just about every paved surface. You’ll get great acceleration, braking and cornering performance from these semi-slick, grippy rubber tires! The tires are molded in a durable, long-wearing rubber compound that will give you a long life for hours of fun and enjoyment. If going sideways is more your style, we also include a second set of wheels fitted with HPI T-Drift tires. These low-profile drift-specific tires are made for high-performance, realistic drift action at 1/10th scale! Just make a quick pit stop to change them over and you’ll be ready to show off your drift skills in no time.

ONE-PIECE MOLDED CHASSIS

The RS4 Sport 3 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.

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 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 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.
