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.

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.

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.

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.

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.

Option: Adjustable Camber Link Turnbuckles

The option set of adjustable turnbuckles will allow you to quickly fine tune the camber setting of your RS4 Sport 3 for optimum performance.

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.

Rear End Chassis Diffuser

The built in rear end chassis diffuser element smooths out the air flow underneath the chassis for maximum aero efficiency.
Rubber-Sealed Ball Bearings

The RS4 Sport 3 is fully fitted with a set of rubber-sealed ball bearings for maximum efficiency. The rubber seals keeps the dust away from the internals while the smooth precision bearings provides for optimum power delivery from the power source out into the driveline.
