Nitro Touring
Car Racing
at its Best

The HB R10 is the latest kit from the talented designers at HB-HPI to enter the exciting, fast and dangerous world of 1/10th scale nitro on-road touring car racing with a unique, high-spec nitro touring car kit that will amaze nitro racing fans! The HB R10 is a no-compromise, top-end fully laden racing machine. No expense or effort has been spared to make the R10 into a car that can compete with the world's best, at the highest level of competition. This makes it the best choice for your racing endeavors, whether you're just getting into nitro touring cars for the first time, are a seasoned racing veteran or are trying out the class after some time away. 

Top-level nitro touring cars are a completely different type of racing class compared to electric touring cars - you can't just add an engine to any touring car design and head off to the races - at least, not if you want to do well. Properly designing and testing a car takes months, even years, taking a full-time design team and several world-class racers. The materials and design have to be at the highest level as well, with many different designs and materials tested over a long period. The HB R10 is packed full of knowledge that only comes from years of collective racing and design experience. 

Why does the R10 need this supreme attention to detail? Because at over 60mph, even on smaller tracks, every single componenent on the car has to serve a purpose and perform at the highest possible level. That's why only the best materials went into the HB R10: titanium, aircraft aluminum, carbon graphite, top-grade composites and more.

The R10 is built from the ground up to perform, and to win. With this car, you can experience the thrill of nitro racing with a World Championship racing team! The HB R10 is a kit, and requires a set of metric hex wrenches to build. You will need to supply your choice of body, mounted foam tires, engine, exhaust, manifold, fuel and starter box. 

Total Control

Like every HB racing kit, the R10 allows you to set and refine every possible adjustment on the chassis. You can tune such parameters as roll center, front and rear arm toe, camber, caster and more. You can fine-tune the chassis roll front and rear with sway bars at each end, and the robust pivot-ball suspension gives you precise control of the camber and rear toe with a quick twist of a hex wrench.

 

Chassis
 
The R10 chassis is CNC machined from aircraft aluminum, and is designed to be extra-narrow, which prevents any rubbing while cornering, which can upset the car when you're going for that perfect lap. Woven graphite of the highest possible quality is used for the upper deck/radio tray and all the stiffeners and supports throughout the car. Thick woven graphite is utilized for the front and rear shock towers for extra crash protection so you can finish the race instead of worrying about damage to the car. The bulkheads, pivot blocks and spacers are all constructed from top quality aluminum and anodized a bright orange. The easily removeable fuel tank sits in the exact center of the chassis, with the battery pack positioned underneath for a completely centralized weight balance.
 
To help lower the CG even further, the servo positioning places them flat on the main chassis for fast weight transfer and superior cornering speeds. The engine mount is a multi-piece unit, allowing both OS and Novarossi style engines to fit straight on. Performing engine swaps and maintenance is simple and easy - the multi-piece mount lets you change engines without having to set the gear mesh each time. An extra-thick foam bumper sandwiched between stiff plastic supports protects the front end of the car, and a carrying handle will help your pit crew make lightning-fast fuel stops!
 

Suspension
 
The R10 was designed fresh from the ground up, however that doesn't mean it ignores design conventions just for the sake of being new and different. The R10 uses proven racing suspension design to give racers of all skill levels all of the tuning capability they want, and without the bother of complex and hard to understand race car suspension theory. The front camber is set by an extremely solid 'pivot ball' design, which gives you infinite control over the track width of the car as well. Simply insert a hex wrench through the wheels and you can do a fast setup change - no turnbuckles necessary.
 
The front caster is set by moving the upper suspension arm forward and backward on a solid hinge pin, giving you precise control of the steering into and out of corners. The rear track and rear is controlled with the same extra-sturdy pivot balls, while the rear camber is set with titanium turnbuckles. The shocks are a normal oil-filled, coil-over design, with threaded bodies and threaded top and bottom caps. The shock bodies are coated with super-slick PTFE for near-frictionless movement of the piston, giving you effortless and smooth suspension movement. Controlling the chassis roll at each end of the car are adjustable sway bars - a blade-style sway bar in the front and a conventional bearing-supported bar style sway bar in the rear.
 

Drivetrain

The R10 has universal driveshafts front and rear, with reinforced drive belts taking the power from the gearshaft to the front end, and to the rear solid diff. The drivetrain is fully equipped with lightweight, hardened aluminum pulleys for low friction, decreased rotating mass and long life. The pulleys are also anodized a cool gunmetal color in a great example of attention to detail. Extra-strong Kevlar-reinforced drive belts transmit the power from the engines to the front and rear 4-gear differentials, which are easily tunable for your driving style and track.
 
A highly efficient 2-speed transmission is fitted as standard equipment, and as a vital part of the car a large amount of attention has been paid to this area of the R10. Using 0.08 Module gears for smaller gear teeth allows lower rotational mass and increased gear life. A centrifugal clutch controls the exact moment the clutch shoes engage the clutchbell for precise control in demanding traction conditions.
