Serpent 903012 Viper 977 1/8 Nitro Touring Kit  [SER903012]

Viper 977 Racing Overview

The Serpent 903012 Viper 977 is a purpose-built 1/8 scale nitro on-road kit engineered for precision and adjustability. It targets drivers who expect a tunable platform for competitive track running without sacrificing durability.

Chassis Engineering and Balance

The chassis is machined from 5mm 7075 T6 aluminium to deliver a rigid yet lightweight base. Its symmetric layout promotes even flex and reliable weight distribution, and the provision for up to three sliding brass weights lets racers dial in front-to-rear balance for different circuits.

Suspension Layout and Steering Setup

Ride control comes from an independent double wishbone suspension paired with RCM shocks for controlled damping. Camber, caster and toe-in are fully adjustable, and the steering blocks include multiple Ackermann choices to refine turn-in and mid-corner feel.

Drivetrain and Power Delivery

Power is transferred through a 4WD belt-drive system and managed by a Centax true motion clutch feeding a compact 2-speed SL8 gearbox. The combination gives predictable acceleration and consistent traction, with a rear solid axle and front one-way bearings aiding handling stability.

Fuel Handling and Robustness

The narrow-profile 125cc fuel tank is designed to limit fuel surge and features a labyrinth path to reduce foaming for steady engine feed. Parts throughout the kit are specified to withstand the demands of race setups and frequent adjustments.

For experienced hobbyists who enjoy set-up work, the Serpent 903012 Viper 977 provides a solid, highly adjustable platform that responds predictably to tuning and upgrade parts.
