HPI Racing Spec-Grip tyres
Rounding out the package are the brand new high performance HPI RACING SPEC-GRIP rubber tyres for maximum grip and fun on the road. Newly designed with a scale realistic side profile, multi condition tread and high traction rubber compound, the HPI RACING SPEC-GRIP tyres represent the next generation of HPI on road rubber tyres.
BMW M3 E30
First released in 1982, the BMW E30 won plaudits from motoring magazines and fans of small, well-built European saloons around the world. The factory-upgraded M3 version, released in 1986, featured distinctive bulged wheel arches to accommodate larger tyres and a wider track, spawning decades of lookalike custom cars.
On the racing circuit, the M3 came to dominate the late 1980s, securing the title of the most successful touring and grand touring car to ever have participated in racing, including victories at the prestigious 24 Hours Nurburgring and the Spa 24 Hours and WRC Tour de Corse.
One-Piece Moulded Chassis
The main chassis is formed from a single piece of reinforced plastic and features the drive-train tunnel moulded 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 centre 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 Drive-train
The drive-train of all the RS4 Sport 3 models features the motor mounted longitudinally in the moulded chassis, next to the long drive-shaft that goes down the centre of the car. The entire drive-train, including the central drive-shaft and gear diffs, is completely sealed to prevent dirt, rocks and debris from damaging or binding the drive-train. The drive-shaft, diffs and axles spin on ball bearings to maximize drive-train efficiency.
The central drive-shaft that connects the front and rear differentials is easily accessed from underneath the chassis. This allows the drive-train 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 drive-shaft to the dog-bones and axles that drive each wheel. The all-metal construction allows the drive-train 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 centre front and rear with the racing-style vertical ball-stud 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
Oil-Filled Threaded Shocks
The RS4 Sport 3 is fitted with a set composite coil-over-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 centre - 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 centre. 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 Bell-crank 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
Fitted to the HPI SF10W waterproof servo is an adjustable multi-piece 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!
Aluminium Motor Mount
The cast aluminium 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.
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 drive-line.
Rugged Front Bumper
To protect the front suspension, chassis and body from impacts big and small, an extra thick foam bumper is securely fastened to the front of the RS4 Sport 3.
Customize Your Look
A huge variety of option bodies, wheels and tyres from HPI lets you fully customize the style of your RS4 Sport 3 to suit your style.
Adjustable Height Body Mounts
The adjustable height body mounts let you fit any 1/10th scale touring car body from HPI Racing on to the RS4 Sport 3 chassis. All you need to do is adjust the front and rear body mounts to allow the wheels and chassis elements to fit properly underneath the body. Body pins hold the mounts in place, and the multiple mounting hole positions allow you to fine-tune the exact body fit.
You can fit any 1/10th scale touring car body from HPI Racing onto the RS4 Sport 3, from hot hatches to super cars, pick-up trucks to super-touring racers. All you need to do is adjust the body mounts front and rear to allow the wheels to fit underneath the body properly. A simple system using body pins hold the mounts in place, and you can fine-tune the fit to get the exact ride height you want.
