SERPENT Serpent Viper 989E 1/8 EP (SER904005)

The Serpent 989E Viper is the latest Electric version of the 989. Electric racing has developed big time, the possible power is huge. Especially in the popular dragster class in the US the power going through the transmission is extreme. The 989E is designed to take care of that power and put it down as effective as possible. The 989E is based on the ultra-successful 989 gas racer and shares it’s suspension, shocks and quite a lot of other features like the chassis plate or the driveshafts

  • Power delivery starts with the batteries. We made room for serious power, 4S, 6S or more. There is plenty of space for them, still they are very low in the car.
  • The batteries are mounted on a 2.5mm thick carbon plate. They can be mounted in 3 different positions, changing the CG to alter the cars behaviour
  • The elevated speedo mounting plate gives stiffness for the battery plates and creates also room for oversized speedos. Even 1-5 scale speedos fit, a very popular choice in the dragster racing scene
  • The topdeck is creating enough stiffness for the whole chassis and carries the receiver, steering-servo and belt tensioner
  • We also took care of the motor. We created the room for a huge range of motor sizes.
  • Even long custom made motors have enough room
  • To avoid unwanted torsional flex, we created a “power box” around the motor, making this part of the chassis very stiff. To achieve this, the motor mounting plate is connected to the bearing-block of the spur gear shaft, to the chassis and to the mounting bracket of the topdeck
  • Power is then transmitted further with unbreakable, module 1 steel gears
  • Further down we changed to a super wide, 10mm rear belt. The power then goes through the solid rear axle which carries a n aluminium pulley as well
  • For the dragster lovers we also offer a wheelie bar as an option.

Overview of the main specs


Symmetrical chassis plate optimised flex and torsion, in 7075 T6 aluminium, anodised and laser engraved. Chamfered edges for more ground clearance when cornering and countersunk holes.

Low big bore shocks

Coated threaded shock bodies in high quality aluminium. Supersmooth x-ring / machined bushing package, to guide and seal the spring- steel piston rods. Precision machined pistons included in 3 types. Threaded pre-load shocknuts in alu with O-ring inside. Light but strong nylon spring-cups. Selected, matched and paired shock absorber springs with colour coding.

Shocktower front & rear

The 3mm carbon fibre front and rear shocktower with 2 positions for the front and 3 positions for the rear for upper shock mounting.

Steering blocks

Very strong composite steering blocks with 2 Ackermann positions, L and R use the same . The steering blocks feature inserts, which allow to change the kingpin inclination to a leading or trailing position. The steering blocks also allow use of the optional carbon fibre aero disks to be mounted for less flex and a more direct steering feel.


Durable medium type composite uprights, which seat the wheel-axles bearings. The upright offers the mounting position for the steel camber-rod with L/R threading. Roll centre changes can be made on top of the upright with shims. The upright can be mounted with the optional carbon fibre aero disks for more rear grip and straight line stability.

Wheel axles and driveshaft

The durable spring steel wheel axles combined with spring steel driveshafts bring the power to the wheels.


Precision moulded super-true pullies, which feature holed sidewalls to let debris move out easier. Light and durabele.


Low friction Kevlar reinforced belts with fine pitch. Longlasting and smooth.


The 989 includes one sheet with Serpent generic logos and one with 989 logos. Decals are very thin material and come pre-cut.
