After the announcement at the beginning of this year, HB Racing have finally released the new D819 1/8 nitro buggy. The latest iteration of the World Champion line of buggies from HB Racing, this racing car adds the latest high performance parts to keep it ahead of the competition.
The chassis is symmetrical for better balance and more consistent jumping and cornering. And it’s strategically machined to decrease weight and balance the flex characteristics. A machined aluminum center chassis brace that strengthens the center section of the buggy, and an updated chassis with countersunk mounting holes for the new brace.
The D819 adds the latest high performance parts to keep it ahead of the competition. This buggy is build 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 chassis is symmetrical for better balance and more consistent jumping and cornering.
The machined aluminum 17.5° front caster blocks are strengthened for improved durability. Drivetrain refinements include new front & rear diff pinion and center outdrive system for easier assembly and maintenance, and new center drive dogbones. A heavy duty machined & lightened steel spur is now included for added durability. The race-proven 4WD system uses tough sintered diff gears, precision machined steel input gears and spur gear, machined aluminum wheel hubs, and steel Universal Joints that are favored by HB’s Team drivers for improved performance on bumpy tracks.
A new machined aluminum engine mount is now a 1 piece design for simplicity, weight savings, and improved reliability. Mounting the engine and setting the gear mesh is easier than ever with the innovative new asymmetric engine mount cams. 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. Included is a new flywheel that allows fitment of the latest engines, and the brake linkage now uses o-rings for improved reliability and more adjustability than springs.
With the release of the D819 HB Racing added a new front B Mount and revised rear hub carrier graphite plates for the latest geometry based on testing and racing around the world. The 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 Australia. The D819 suspension includes new narrow hubs to help meet width regulations with most wheels, front and rear machined aluminum shock towers, adjustable turnbuckles, front and rear sway bars with new 1 piece links, hinge pin inserts for easy toe and anti-squat settings, machined aluminum caster blocks, steering blocks, and new carbon graphite rear upright plates with improved geometry. Also included is our narrow rear shock tower that is a favorite of their Team drivers for its more useful range of adjustment.
This buggy’s steering system is built for durability and easy adjustment. It features an aluminum servo saver arm and clamping servo saver adjustment nut, steel turnbuckles, aluminum drag link, highly adjustable Ackerman geometry using steering knuckle plates, and CNC machined aluminum steering blocks. This buggy includes aluminum front linkage geometry spacers that replace the plastic spacers for improved bumpsteer geometry, more precise adjustment, less flex, and we revised the screw lengths to accommodate the new spacers.
Topping the D819 kit is the new JConcepts Silencer S15 clear body, a popular choice with the HB team drivers. HB Racing have included the HB molded nylon wing that is lightweight and durable. The popular one-piece high wing mount is standard equipment, which raises the wing 10mm, putting the wing in less turbulent air flow to help produce more downforce.
