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 Flux features the utterly unique #17 Porsche 911 GT3 RSR driven by Bryan Sellers, Wolf Henzler and Nick Tandy for the Falken Tire racing team, one of the top race teams in the super-competitive GT Class of the American Le Mans Series. The iconic shape of the Porsche 911 combined with the jaw-dropping ''urban camo'' look and stylized shark-mouth make for the perfect head-turning look for the fastest version of the all-new RS4 Sport 3. Finishing the race car look are a set of our extra-wide (31mm and 35mm) replica BBS wheels fitted with matching slick racing tires!
Propelling the RS4 Sport 3 to speeds over 124km/h (70mph) is the Flux MMH-4000KV motor, controlled by the waterproof Flux EMH-3S LiPo-ready speed controller. An enclosed box houses the 2.4GHz radio receiver, ensuring that you have constant control through the HPI pistol-grip steering wheel transmitter.
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. Bevel gear diffs at each end of the car transfer power from the driveshaft to the dogbones and axles that drive each wheel. The entire drivetrain, including the pinion and spur gears, central driveshaft and gear diffs, is completely sealed to prevent dirt, rocks and debris from damaging or binding the drivetrain.
On the opposite side of the chassis to the motor, speed controller and servo, the battery box is large enough to fit any standard battery size, even NiMH 7-cell batteries, held in place by a large hook-and-loop strap. The battery box is also adjustable, so you can decide if you want more traction and move the battery towards the rear of the car, or more steering by moving the battery towards the front.
The suspension of the RS4 Sport 3 uses the race-proven double-wishbone suspension design that real racing cars use, so not only does it look realistic and cool, it''s also instantly familiar for racers to get used to. To control the bumps and gradients that the car will drive over, the RS4 Sport 3 is fitted with composite coilover-style oil-filled shock absorbers, just like what you''d see on a real sports car. Tuning the suspension is made possible with alternate shock mounting locations, and many options such as springs, aluminum shocks and carbon fiber shock towers will be available for anyone wanting to make this into a formidable club racer.
The RS4 Sport 3 Flux is the latest HPI touring car to take on the challenge of continuing the venerable RS4 Sport name!
