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
•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
Superlow 3.0mm carbon fibre shocktower with 3
positions for upper shock mounting. In the
centre you can mount the 3rd body post as
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 durable.
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.
The batteries are mounted on a 2.5mm thick carbon plate.
There is also room for a 1-8 scale speedo, 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 made a mount for a 10th scale motor.
And also we made a optional mount to fit a 8th scale motor.
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 topdeck
Power is then transmitted further with unbreakable, module 1 steel gears.
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
For the dragster lovers we also offer a wheelie bar as an option.
