Serpent 904005 Viper 989E 4WD 1/8 Touring Race Kit  [SER904005]

High Performance Touring Chassis Serpent 904005 Viper 989E

Serpent's 904005 Viper 989E brings race-oriented features into a tunable 1/8 electric touring car. With Michael Salven's input, the package targets drivers who prioritise consistency and precise setup changes.

Versatile Power and Weight Tuning

This platform accepts battery configurations from 4S to 6S, giving a wide powerband. Batteries sit on a 2.5mm carbon plate with three selectable positions so you can shift the centre of gravity. A raised speedo mount offers support and space for larger speed controllers commonly used in high-output builds.

Chassis Built for Controlled Flex

The symmetrical 7075 T6 aluminium chassis is engineered for a balance of stiffness and controlled flex. The top deck secures the receiver, steering servo, and belt tensioner to maintain alignment under load. A motor-centred power box reduces chassis deformation near the drive train.

Responsive Dampers and Setup Range

Low big bore aluminium shock absorbers feature x-ring seals and machined bushings to deliver predictable damping. The 3mm carbon shock towers provide multiple mounting points so you can tune roll centre and rebound for different track surfaces.

Fine Tuning Steering Characteristics

Composite steering blocks include options for altering Ackermann and kingpin inclination via inserts, enabling adjustments to turn-in aggressiveness and mid-corner balance. Optional carbon fibre aero disks can be fitted for improved aerodynamic stability.

The Serpent 904005 Viper 989E is a solid base for tuners and racers who want a platform that responds well to setup changes and can handle aggressive electronics choices.
