The Serpent 750E Natrix is the latest Electric version of the 750. 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 750E is designed to take care of that power and put it down as effective as possible. The 750E is based on the ultra-successful 750 gas racer and shares it’s suspension, shocks and quite a lot of other features like the chassis plate or the driveshafts

Overview of the main specs
•Front bumper and bodymount
 The new front bumper has an improved
 aerodynamic effect and excellent protection.
 Medium or small foam bumper pad can still be
 fitted as optional. The upper carbon fibre
 body plate mounts to the front bumper with alu
 post and secures the front body posts
 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
•Shocktower front
 Superlow 3.0mm carbon fibre shocktower with 3
 positions for upper shock mounting. In the
 centre you can mount the 3rd body post as
•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. Wheels are fitted on high grade
 anodised alu wheel-hex adaptors and secured
 with flanged wheel nuts.
 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.
 Ball raced belt-tensioner, machined from
 aluminium and can mount on top or below the
 The 750 includes one sheet with Serpent
 generic logos and one with 750 logos. Decals
 are very thin material and come pre-cut.

Power delivery starts with the batteries. We made room for serious power, 4S or 6S batteries. There is plenty of space for them, still they are very low in the car.

For the dragster lovers we also offer a wheelie bar as an option.

Further down we changed to a super wide, 9mm rear belt. The power then goes through a solid rear axle, especially suited for dragster racing

Power is then transmitted further with unbreakable, module 1 steel gears.

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 topdeck

And also we made a optional mount to fit a 8th scale motor.
Even long custom made motors have enough room

We also took care of the motor, we made a mount for a 10th scale motor.

The topdeck is creating enough stiffness for the whole chassis and carries the receiver, steering-servo and belt tensioner.

There is also room for a 1-8 scale speedo, very popular choice in the dragster racing scene

The batteries are mounted on a 2.5mm thick carbon plate.
