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

Track-Oriented Serpent 904005 Viper 989E Touring Chassis

The Serpent 904005 Viper 989E is a 1/8 scale electric touring car designed for precise adjustment and competitive driving. Michael Salven's design influences are evident in the car's emphasis on setup versatility and component strength.

Battery and ESC Configuration Flexibility

The model supports battery packs from 4S to 6S and offers three battery mounting positions on a 2.5mm carbon plate for tuning the centre of mass. An elevated speedo mounting plate increases clearance and supports larger speed controllers used in higher-power builds.

Aluminium Chassis with Controlled Flex

The symmetrical 7075 T6 aluminium chassis is engineered to manage flex and torsion for consistent handling. The top deck secures the receiver, steering servo and belt tensioner to maintain drivetrain alignment. A motor-area power box reduces flex around the drive components.

Tuned Suspension Components

Low big bore aluminium shocks fitted with x-ring seals and machined bushings deliver reliable damping performance. The adjustable 3mm carbon fibre shock towers provide a range of mounting points for roll and ride height adjustments depending on track demands.

Steering Adjustability for Fine Balance

Strong composite steering blocks include adjustable Ackermann and inserts for kingpin inclination, enabling nuanced steering setup. Optional carbon fibre aero disks can be fitted to steering blocks and uprights to aid high-speed stability and tyre contact consistency.

The Serpent 904005 Viper 989E is aimed at experienced modelers and racers who want a chassis that accepts detailed setup changes and performs reliably under demanding conditions.
