Serpent 903019 Viper 989 40th Anniversary 1/8 GP Touring Car - Track Tuned  [SER903019]

Four Decades Refined: Serpent Viper 989 40th Anniversary

The Serpent Viper 989 40th Anniversary edition celebrates Serpent's ongoing focus on race-ready engineering. This 1/8 scale nitro touring car is built for drivers who value precise handling and the ability to fine-tune setup for different track conditions. The package combines careful chassis engineering with practical features for competitive layouts.

Chassis Engineering and Weight Control

The Viper 989 uses 7075 T6 aluminum for a chassis that is both light and rigid where it matters. Its ultra-narrow profile improves flex response while lowering mass. Machined reliefs cut stress concentrations, and a carbon weight bridge with anti-vibration rubbers helps tame vibrations. A front sliding weight lets you dial in balance to reduce traction roll during corner entries.

Suspension and Steering Details

Suspension on the Viper 989 employs pivot ball link geometry for accurate adjustment and consistent feel. Steering blocks use spring steel pivot balls paired with nylon cups for durable, low-friction movement, and adjustments are made with a simple hex tool. The included "Option 2" steering levers provide an alternate Ackermann curve for a more predictable steering response at speed.

Drivetrain and Gearbox Features

The car benefits from an updated midshaft assembly that streamlines belt tensioning and reduces the count of tensioners needed, resulting in a freer-running transmission. Spring steel CVD shafts front and rear deliver durability, and a low inertia 2-speed gearbox smooths acceleration shifts. NSK bearings throughout the transmission improve longevity and reduce drag.

Upgrades and Personal Setup

Owners can tailor the Viper 989 with a broad selection of option parts to change handling, weight distribution, and looks. From carbon components to alternative suspension parts, the platform supports a wide range of performance and aesthetic upgrades to match your driving style.

For experienced RC racers seeking a tunable 1/8 nitro tourer, the Serpent Viper 989 40th Anniversary stands out thanks to its balanced chassis and race-oriented options.
