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

Viper 989 40th Anniversary Edition - Race Focused Engineering

The Serpent Viper 989 40th Anniversary brings matured race design into a 1/8 nitro touring package. Crafted for competitors who want predictable handling and easy setup changes, this car pairs lightweight materials with practical tuning features to keep lap times consistent.

High Strength, Low Weight Chassis

The Viper's chassis is CNC-machined from 7075 T6 aluminum to balance stiffness and weight savings. Its slim profile promotes controlled flex, while machined reliefs cut stress build-up. The carbon weight bridge with anti-vibration rubbers reduces harsh feedback, and a front sliding weight offers quick balance adjustments to combat traction roll.

Steering Precision and Suspension Tuning

Pivot ball link suspension delivers clear feedback and repeatable handling. Spring steel pivot balls in the steering blocks run against nylon cups for low maintenance and smooth action, with tuning done using common hex wrenches. The "Option 2" steering levers shift the Ackermann to give a more direct steering response at race pace.

Efficient Power Delivery and Gearbox

A revised midshaft assembly streamlines belt tensioning by cutting down on required tensioners, which helps the transmission run more freely. Durable spring steel CVD shafts carry power front and rear, while the low inertia 2-speed gearbox produces smooth acceleration transitions. NSK bearings are used to keep drivetrain losses low.

Options for Setup and Styling

There is a broad selection of optional parts to personalise the Viper 989, from aerodynamic carbon pieces to alternative suspension components. These upgrades let drivers tune handling, weight and appearance to suit their race strategy.

The Viper 989 40th Anniversary is well suited to seasoned RC drivers who want a tunable, race-capable 1/8 nitro chassis with solid upgrade paths.
