The Serpent Viper 989 40th Anniversary brings decades of development to a 1/8 nitro touring platform. It is intended for drivers who require fine control over setup and consistent behaviour through varying corners. Thoughtful engineering and serviceable parts make it a strong contender on technical tracks.
The chassis is made from 7075 T6 aluminum to deliver the strength needed while keeping mass low. Its narrow layout influences flex in a positive way, improving responsiveness. Carefully milled sections reduce load points, while a carbon weight bridge fitted with vibration-damping rubbers lowers unwanted shake. A front sliding weight gives easy adjustments to the car's handling balance.
Pivot ball link suspension allows precise corner tuning and predictable feedback. Steering blocks feature spring steel pivot balls and nylon cups to reduce wear, with adjustments performed via hex tool. Switching to the "Option 2" steering levers alters the Ackermann profile for a steadier steering feel at higher speeds.
A redesigned midshaft assembly simplifies belt routing and reduces the number of tensioners required, which helps the transmission run freer. Spring steel CVD shafts at both ends give robust power transfer, and the low inertia 2-speed gearbox ensures crisp acceleration. NSK bearings throughout the drivetrain add to dependable operation.
Racers can fit a range of optional components to tailor the Viper 989's handling and appearance. From aerodynamic carbon parts to alternate suspension pieces, the platform supports straightforward upgrades for lap-time improvements.
The Viper 989 40th Anniversary is aimed at serious hobbyists who want a tunable, race-capable 1/8 nitro car with a solid upgrade path.
