The Serpent 904005 Viper 989E reflects Serpent's focus on race-ready engineering and tunability. Created with input from Michael Salven, this 1/8 scale electric touring car blends adjustable design with robust components to suit competitive RC drivers.
The Viper 989E accepts multiple battery setups from 4S up to 6S, giving drivers flexible power options. Batteries mount to a 2.5mm carbon plate with three selectable positions to fine-tune weight distribution. The raised speedo mounting plate adds strength and leaves clearance for larger speed controllers used in high-power applications.
Its symmetrical 7075 T6 aluminum chassis is tuned for controlled flex and torsional strength. A rigid top deck carries the receiver, steering servo, and belt tensioner to keep vital components secure. Around the motor a reinforced power box reduces unwanted flex and raises overall chassis stiffness.
Ride quality and control come from low big bore aluminum shocks with precision x-ring seals and machined bushings for consistent damping. Adjustable 3mm carbon fibre shock towers provide multiple mounting options so racers can dial in handling for a wide range of surfaces.
Steering uses durable composite blocks with variable Ackermann settings and inserts to change kingpin inclination, letting drivers tweak turn-in and mid-corner balance. Optional carbon fibre aero disks can be fitted to steering blocks and uprights to aid stability and tyre contact.
The Serpent 904005 Viper 989E suits advanced hobbyists looking for a platform that balances durability with precise adjustability. It rewards setup work and is a strong base for competitive touring or tuning practice.
