RS4 Sport 3: the icon is back!
The RS4 Sport 3 is the all-new touring car chassis from HPI Racing! In development and refined for over a year, the RS4 Sport 3 features a completely sealed and highly efficient shaft drivetrain, coilover shock absorbers plus waterproof electronics. The fully contained drivetrain means there are no exposed gears, belts or drivetrain parts to get stuck with rocks or dirt. Finally, the RS4 Sport 3 is finished with realistic tires plus a licensed replica body and wheels for an authentic look that will grab the attention of all RC and motorsport enthusiasts!
The first RS4 Sport 3 Drift features the HPI Racing x FATLACE liveried Subaru BRZ, a super-popular sports car and phenomenal drift machine. Complementing the stunning HPI Racing x FATLACE livery are a set of replica Yoshihara Design Champion wheels in silver and replica Falken Azenis RT615K HPI T-Drift tires, for instant easy drift action!
The HPI Firebolt 15-turn motor powers the RS4 Sport 3, and it's controlled by a waterproof HPI speed controller for reliable and trustworthy operation. An enclosed box houses the 2.4GHz radio receiver, ensuring that you have constant control through the HPI pistol-grip steering wheel transmitter.
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
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.
2S LiPo CAPABLE
The RS4 Sport 3 features a versatile electronic speed controller that can be used with modern lithium polymer (LiPo) or nickel-metal hydride (NiMH) batteries. Please note a LiPo adapter plug is not included, your model shop will be able to provide one.
Fits a Wide Variety of Batteries
The RS4 Sport 3 chassis can fit lithium-polymer and nickel-cadmium packs of various sizes, including the extra-long 7-cell Ni-MH packs. Whatever your power requirements, it can hold it all! A thick hook-and-loop strap holds the pack securely in place, and a simple battery block screws into place to allow you to adjust the weight distribution forward or backward for extra steering or acceleration.
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.
