REALISTIC AERODYNAMIC BODY DETAILS
The HPI Racing 1/10th scale Falken Tire Porsche 911 GT3 RSR authentically replicates the extensive aerodynamic details of it’s full scale counterpart with the adjustable replica rear wing, multi piece rear diffuser and side body aero pieces behind the front wheels.
The car not only looks fantastic when standing still, but really works to add downforce to the rear of the car while it moves at speed.
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.
3S 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. The speed controller is fitted with an official high-current Dean's Plug, which means you can use use 2S or 3S lithium-polymer batteries, including any of the range of HPI Plazma batteries.
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.
HPI Flux Technology for Ultra-Fast Speeds
What sets apart the RS4 Sport 3 Flux from our other offerings is the HPI Flux brushless power installed in every Flux-powered machine. The RS4 Sport 3 Flux is fitted with the awesome Flux MMH-4000 motor, one of our most powerful motors for 1/10th scale cars. Thanks to the robust Flux EMH-3S speed controller, you can strap in your choice of 2S or 3S LiPo power (or a 7.2v-8.4v NiMH battery with a Dean's plug) to give the car an unbelievable power out of the turns and speeds of up to 70mph (124km/h) on the straight, when using optional gearing!
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.
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.
Option: Carbon Fiber Driveshaft Cover
You can easily replace the stock driveshaft cover on the bottom of the chassis with a carbon fiber cover that provides extra stiffness and extra-cool looks.
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.
Option: Diff Spool
The optional diff spool removes all diff action for direct traction and braking action from your trigger finger straight to the wheels.
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.
MULTIPLE SHOCK POSITIONS
Option: Carbon Fiber Shock Towers
The option pair of carbon fiber shock towers not only look amazing, but also adds extra stiffness to the suspension for optimal performance. The carbon fiber material is extra-lightweight which lowers the center of gravity on the RS4 Sport 3 as well.
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.
Option: Anodized Aluminum Threaded Shocks

Rugged Spring-Loaded Servo Saver
Fitted to the HPI SF10W waterproof servo is an adjustable multipiece 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 internals 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.
