    HB D815 Ty Tessman Worlds Edition 4WD Competition Nitro Buggy Ki

    Price:   $750.00 $899.00

Racing car development is a never-ending process, and the same is true with World Championship-winning RC cars. After multiple National Championships and dominating major races such as The Dirt and the Neo '14, Ty Tessmann and his HB D812 won the 2014-2015 IFMAR World Championships in Sicily, his first world title win! Although much of the credit is owed to Ty's skills and dedication, as well as unending help from the rest of "Team Tessmann", Ty's weapon of choice deserves a fair amount of acclaim as well. The HB D812 was a development of the 2008-2009 World Championship-winning D8, and has been a stalwart addition to the HB stable of pure racing cars for a few years, and the HB D815 is the culmination of this work - tried and tested, and victorious at the highest levels of competition.
The HB D815 is the perfect evolution of the existing car, featuring many all-new parts that turn the D812 from a worthy challenger into a definite winner in the right hands. A series of refinements like an improved center drivetrain, aluminum servo saver arm and sintered brake pads takes the D815 up a few extra notches to improve its reliability and durability on the track, while the car keeps the parts that have helped make it into arguably the toughest racing buggy in the world. Fast work in the pits is a requirement for modern racers, and the D815 makes quick maintenance part of its wide repertoire, with a new one-piece radio tray and new split center bulkhead.
The D815 is not just your standard racing buggy - it's packed full of details that can only be seen under close inspection. Its racing heritage is evident by looking over its lightweight parts, including the diff outdrives, center inputs, spur gear, diff gears, aluminum front axles, chassis braces, shock towers, wing mount, rear wing and woven carbon fiber steering arms and rear camber link points. Signature features such as the stand-up servo mounting, monocoque suspension arms, machined aluminum outer suspension pieces and woven carbon fiber steering arms and rear camber mounts have been retained not simply because they are unique features, but because they help the D815 race hard in the toughest main events without worrying if it can finish.


The D815 Tessmann Worlds Edition is as close to a World Championship-winning car as you can get. A host of extra-tough parts feature throughout the D815 to help it maintain its legendary reliability record, such as extra-tough, lightweight diff gears in a new 43/13 ratio, rubber CVD boots, new CVD boots over the center CVDs, thick steel turnbuckles, machined engine mount and 3mm 7075 chassis with a steel rear skid plate. 16mm big bore threaded coilover shock absorbers and stiff monocoque suspension arms stand out among the suspension parts, however the suspension also features front and rear sway bars, hinge pin inserts for easy toe and anti-squat settings, fine adjustment of the rear camber link locations plus brand new machined aluminum caster blocks, steering blocks and new rear uprights. The steering system features a new alloy servo saver arm, aluminum drag link, steel turnbuckles and woven carbon fiber steering arms on the steering blocks. Alternate arm mounts, steering blocks, caster blocks, steering arms, rear hub carrier arms and sway bars are all available to tune the D815 to any track or driving style.
Finishing the long list of standard equipment on the HB D815 are orange aluminum color accents throughout the car. The HB D815 is the finest-built and most-equipped off-road racer available, carrying its World Championship heritage to race tracks and pit areas around the world.


The D815's all-new diff gears are precision-machined from hardened aluminium and feature a new gear ratio that is suited for modern race tracks. The diff gear set features a one-piece input gear that improves the durability of the drivetrain dramatically by reducing parts to the bare minimum. 


The D815 features brand new front and rear suspension parts, including front caster blocks and rear uprights with carbon fiber arms plus an aluminum servo saver arm that drastically improves the strength of the steering system - perfect for long, hard-fought races on tight race tracks. 
Interview about the HB D815 with Ty Tessmann
From his early days racing the Lightning buggy, Ty has become one of the few racers who has a real chance to win at any track, against the toughest competition in the world. Ty celebrated his first World Championship win in late 2014 and quickly got back to developing the D815 as soon as he got back home to Canada.
What makes the D815 so special for you to drive?
The D815 is not only driveable, meaning it's easy to drive, but it also handles really good on the track. I can change whatever I need for the track I'm racing on, plus it's super durable, I don't have to worry about it falling apart or breaking during an hour-long main.
What's new on the D815 that makes it even better than the D812?
We've put a lot of work into developing the D815 so it has more grip in the rear end and it feels better at high speeds, the rear roll center adjustments we can do now are a big change for us to make it handle better, so it does exactly what you want it to do. Also the drivetrain is simpler so it's stronger, with a lower weight and it's more free now for less resistance.
Are there any special new parts that especially helped you win the Worlds?
The new caster blocks have an extra inner hole that I used in Sicily, and also with the new steering blocks I was able to run 20 degrees of caster, which really helped settle the car down at the higher speeds. Those parts and the new rear hubs really helped me win at the Worlds.
I'm really looking forward to the 2015 season with the D815, if you're at the track, come by and say hi! I'm pretty quiet normally but I'll do my best to help you out.
