SERPENT NATRIX 750-E 1/10 4WD EP CAR

Natrix 750-e 1/10 4wd EP 

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 

Chassis 

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 

Superlow 3.0mm carbon fibre shocktower with 3 

positions for upper shock mounting. In the 

centre you can mount the 3rd body post as 

needed. 

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. 

Uprights 

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. 

Pullies 

Precision moulded super-true pullies, which 

feature holed sidewalls to let debris move out 

easier. Light and durabele. 

Belts 

Low friction Kevlar reinforced belts with fine 

pitch. Longlasting and smooth. 

Belt-tensioner 

Ball raced belt-tensioner, machined from 

aluminium and can mount on top or below the 

topdeck. 

Decals 

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.
