The full-size Hoonicorn RTR is a totally custom, all-out drift machine that was designed by Formula Drift champion Vaughn Gittin Jr.'s RTR design studio and built by ASD Motorsports over 2 years to exacting specifications. It's fitted with a monstrous 410 cubic inch V8 putting out nearly 850 horsepower at a screaming 9000RPM. The engine is mated to a 6-speed Dakar Rally-spec transmission and 4WD drivetrain, with a completely custom adjustable suspension, and 3-piece fifteen52 wheels wrapped with super-wide 18-inch tires made in a custom compound just for Ken Block himself. You can read about the inspiration and design of the one-of-a-kind Hoonicorn RTR in this Speedhunters special article by Vaughn Gittin Jr!

fifteen52 R43 Replica 3 Piece Wheels

Custom-forged and machined by the custom wheel experts at fifteen52, the amazing 3-piece R43 wheels are replicated in exacting 1/10th scale directly from the original CAD files, so each and every Hoonicorn RTR replica has the perfect look and street stance. The real 18" x 10.5" wheels are made from machined forged 6061 aluminum centers and forged stepped & polished lips, while the replica is molded in high-impact nylon in a custom gold color. 

Replica Hoonicorn Tires

295/30/18 - magic numbers that give the technical side of Ken Block's full-size hoops that are fitted to all four corners of the Hoonicorn RTR. But numbers can't tell the whole story - especially when these tires are made in a custom compound especially for Ken Block himself! The replica tires look exactly like the real thing: extra-wide, semi-slick and super-cool! The scale tires are molded in a durable, long-wearing rubber compound that gives enough grip for awesome acceleration!

Official Replica of the Amazing, Custom Hoonicorn RTR

Taking the full-size Hoonicorn RTR with its handmade custom body and making it 1/10th scale was a major challenge for the HPI design team, but after months of hard work with scale drawings and hundreds of pictures of the real car, we're proud to call the 1/10th scale Hoonicorn RTR one of HPI's finest achievements. The replica wheels were even made with the help of the original fifteen52 CAD files to replicate their Ken Block special R43 wheels to complete the Hoonicorn's look, and each wheel is wrapped in a scale replica extra-wide semi-slick rubber tires.

Underneath all this detail and awesomeness is the RS4 Sport 3 chassis, the latest scale touring car chassis from HPI Racing! The HPI RS4 Sport 3 chassis features full-time 4WD, 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. The car is completely assembled and fitted with the 1965 Ford Mustang Hoonicorn RTR body and fifteen52 wheels right out of the box, so all you have to do is PLUG IN AND DRIVE!

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 Drift 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 optimum cornering capabilities.

2S LiPo Capable

The RS4 Sport 3 Drift 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.

Full-Time Four-Wheel Drive

The RS4 Sport 3 Drift 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 Drift 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.

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. 

Double-Wishbone Fully Adjustable Suspension

The suspension of the RS4 Sport 3 Drift 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 Drift 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.

Customize Your Look

A huge variety of option bodies, wheels and tires 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 fitment.

Body Choices

You can fit any 1/10th scale touring car body from HPI Racing onto the RS4 Sport 3, from hot hatches to supercars, pick-up trucks to supertouring 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.
