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

Serpent 904005 Viper 989E Race Tunable Electric Touring

The Serpent 904005 Viper 989E combines race-focused ideas with accessible adjustability for 1/8 scale electric touring racing. Michael Salven's design input helps deliver a chassis that responds to detailed setup changes.

Power Setup and Centre of Gravity Options

The car supports 4S up to 6S battery configurations to match different power goals. The battery sits on a 2.5mm carbon plate with three placement options so you can tailor balance. An elevated speedo plate adds clearance for larger ESCs and contributes to chassis rigidity.

Robust Aluminium Chassis Design

A symmetrical 7075 T6 aluminium chassis is used to provide a mix of torsional strength and measured flex. The top deck secures receiver, steering servo and belt tensioner for precise drivetrain alignment, while a motor-surround power box reduces local flex.

Shock Performance and Setup Flexibility

Low big bore aluminium shocks with x-ring seals and machined bushings deliver consistent damping. The 3mm carbon shock towers give multiple mounting options so you can tune roll stiffness and ride height for different track conditions.

Steering Adjustments for Better Cornering

Composite steering blocks include adjustable Ackermann and kingpin inclination inserts to refine steering response and stability. Optional carbon fibre aero disks can be fitted to steering blocks and uprights to improve tyre load distribution under high-speed cornering.

For tuners who value a strong platform and wide setup range, the Serpent 904005 Viper 989E provides a reliable starting point to refine handling and straight-line performance.
