World Champion Quality in an RTR Package
The D8S combines everything you can want for top-level buggy racing into one convenient package - just add fuel and batteries and get on the track! With the World Championship-winning heritage behind the HB D8 combined with the ready to run flexibility of HPI radio gear and the bulletproof Nitro Star F3.5 engine, you can easily get the best of both worlds as soon as you open the box. Race-proven by World Champions and backed by HPI, you can't go wrong with the HPI D8S. Because the D8S chassis and suspension parts are exactly the same as the HB D8, the D8S is ready to upgrade with Atsushi Hara Edition parts from HB!
 

 
All of the latest HPI kits are now fitted with the comfortable and feature-packed HPI 2.4GHz radio system for supreme control and confidence! The latest digital 2.4GHz radio technology allows you to confidently drive your HPI kit with other drivers without worrying about things like frequencies or radio conflicts. The radio features a pistol-grip design with drop-down steering wheel, 3 channel functionality, easy carry handle, fold-down aerial, end point adjustments, servo reversing and steering dual rate. It's also extremely lightweight due to it requiring only four AA batteries. This is a fully-featured, lightweight, 3-channel radio with advanced ergonomic features and total adjustability. Set the radio up for your car with custom features like servo reversing, centre trim, end point adjustments, dual rate and more. Only 4 AA batteries are required to power the transmitter, so it's light in your hands, and the drop-down steering wheel makes it comfortable to hold. With the adjustable, built-in failsafe feature, you will be protected in case the radio ever loses signal.

World Champion Design
The D8S is a 'race roller' version of the HB D8, making it the perfect way to jump into nitro buggy racing! With the design and capability of the World Champion D8 as its foundation, the D8S is your introduction to race-winning glory!
 
 
Powerful F3.5 Racing Engine
Driving the D8S forward is the F3.5 engine, which has been an extra-strong engine fitted in Savage monster truck and Trophy buggy kits for many years. The F3.5 is equipped with a pullstarter for easy starting without an expensive starter box, and it can also be started using a starter box for twice the convenience. For maximum power, the F3.5 is fitted with an aluminium tuned pipe for plenty of wheel-spinning torque off the line and loads of top speed at full RPM!
 
 
Race-Ready Electronics
The D8S is fully equipped and ready to race. With the 2.4GHz radio, you can adjust everything you'd expect on more expensive computer radios. The SB-5 steering servo is extra-powerful to handling full-throttle race conditions, which means it can handle the punishment of steering the wheels at full speed, the ultimate test of a servo's strength.
 
 
Easy to Remove Radio Tray
Aiding clean-up of the chassis at the end of the race day is the easily removable radio tray, just a few screws takes all the electronics out of the chassis to keep fluids and water away from expensive servos, receiver, etc. We know racers like to get dirty, but a clean car is a happy car! (Note: Servos shown in picture are for illustrative purposes only.)
 
 
HB Composite Chassis Braces
Strong composite chassis braces connect the front and rear bulkheads to the middle of the chassis for extra rigidity. Special composite material is used for extreme light weight, helping to enhance the driving feel, acceleration and braking of the car.
 
 
Championship Suspension
With the race-winning suspension design and features of the D8 on board, you will experience a pure driving feel and total adjustability like never before! Tune the D8S to your driving style and track conditions with the aid of the full range of adjustments: shock position, oil, springs, roll centre, wheelbase, camber, sway bars and more! the front suspension features a long list of features, including the HB Inverse Steering Block Design, adjustable roll centre, thick turnbuckle links, aligned king pin and universal joint pivots, sway bar, steel turnbuckles and HB's own counter-rotating shock mount screws.
 
 
Reliable Rear End
At the rear end, the D8 has everything you'd expect from an all-out competition kit, with optional hinge pin holes for the uprights, adjustable roll centre, thick turnbuckle links, sway bar, steel turnbuckles and HB counter-rotating shock mount screws on the suspension arms.
 
 
HB's Unique Solid Suspension Arms
The D8 solid suspension arms prevent mud build-up and also stop rocks from binding the suspension. The exact compound of composite material used is a Team HB secret, and was developed over months of testing in wet and dry racing conditions. Each suspension arm also features handy travel-limiting droop screws to allow you extra tuning ability when you're up against the clock and the competition.
 
 
Point-and-Shoot Steering
The D8S steering system uses thick anodized aluminium steering bar and thick steel turnbuckles to guide you through the pack during a race. Steel screws, locking nuts and sturdy nylon steering arms and turnbuckle links complete the steering. A hand-adjustable servo saver provides extra peace of mind for your steering servo, and four sealed ball bearings let the steering glide effortlessly in the muckiest of conditions.
 
 
HB D8 Big Bore Shocks
The HB Big Bore shocks are MASSIVE - at 16mm across, they are among the biggest shocks you can find on any racing kit. With rubber boots, hard-anodized bodies and threaded adjustments, they have all the standard features you'd expect from any top-level competition kit.
 
 
High Efficiency Shaft 4WD Drivetrain
The D8S is equipped with the World Champion drivetrain straight out of the D8 buggy - three oil-filled gear diffs with spiral-cut gears, full-time shaft 4WD drivetrain supported by rubber-sealed ball bearings, high-strength steel driveshafts and axles and much more!
 
 
Easy-Tune Dual Brake Disc Setup
Controlled braking ability is provided by the front and rear, individually adjustable brakes. Constructed of thick fibre and drilled for low rotating mass and extra cooling ability, the brakes are extremely powerful without being too 'grabby'. They're also extremely easy to tune because of the accessible linkage.
 
 
Built to Last - Without E-Clips!
The suspension mounts front and rear are machined from sturdy aluminium and anodized to match the chassis and steering plate. A steel screw and washer hold the suspension hinge pins firmly in place so you don't have to worry about them falling out on the track.
 

HPI makes it as easy as possible to get into RC off-road action. The D8S is completely pre-built and ready to go right out of the box! Everything is assembled and tuned for you by professionals - diffs, shocks, suspension and more are perfect before you even open the package. HPI Ready-To-Run vehicles bring you the same high performance and quality that you'd expect from a high end RC kit but with the added convenience of being factory pre-assembled to the highest standards - giving you a high performance RC buggy straight from the box!
 
 

Just like all HPI cars and trucks, you get a full, in-depth instruction manual with step-by-step instructions that allow you to easily disassemble and reassemble your car for maintenance and easy servicing. The manual also includes a handy parts list and full-scale drawings of the parts and hardware. And the included HPI RC Car DVD is your personal RC car expert in a box!
