New from HB Racing is the D817 1/8 scale nitro buggy. Fresh off the win at the 2016 IFMAR World Championships in Las Vegas with David Ronnefalk at the wheel, the D817 has proven it's a winner. That's back-to-back World titles for the D815 and D817 in the most competitive class in RC racing. The new D817 adds key features based on extensive testing and racing by our HB Team Drivers and designers.

The foundation for the D817 starts with a 7075 aircraft aluminum chassis that adds 4mm of length to the rear of the car which allows a longer wheelbase (up to the maximum regulation) and shifts the overall center of gravity for more stability, especially on high-speed corners. The new chassis is now symmetrical for better balance and more consistent jumping and cornering. And it's strategically machined to decrease weight and balance the flex characteristics.
A one-piece CNC engine mount holds the engine in place on the 7075 alloy chassis. A complete competition 3-shoe clutch is included, along with sintered brake pads and double ground brake discs for fade free braking and consistent brake feel. Fully adjustable brake/throttle linkage is standard, as well as a racing fuel tank with stone clunk, and a lightweight foam air filter. A convenient covered electronics box allows easy removal for cleaning and maintenance, and easy access to servos.

Reliability has always been a trademark of the winning cars from HB Racing, and the D817 continues that tradition. Its race-proven 4WD system uses high strength steel center drive shafts, tough sintered diff gears, precision machined steel input gears and spur gear, and machined aluminum wheel hubs. New for the D817 are steel Universal Joints that our Team Drivers favor for improved performance on bumpy tracks.

The D817 suspension features the unique HB Racing monocoque suspension arms that allow fine tuning of the stiffness of the front and rear arms to suit track conditions and driving styles. Racers can adjust the grip and feeling of the arms using optional stiff arms and carbon plates to increase the torsional stiffness of the suspension arms, which gives the car a more forgiving feeling at the limit, especially on high-speed and high-traction corners.

HB Racing big bore threaded coilover shock absorbers help soak up extreme bumps, jumps and potholes like our Team Drivers found on the World Championship track in Las Vegas. And the suspension includes front and rear machined aluminum shock towers, adjustable turnbuckles, front and rear sway bars, hinge pin inserts for easy toe and anti-squat settings, machined aluminum caster blocks, steering blocks and new rear uprights with improved geometry.
