SERPENT HERITAGE:

Serpent has started developing and manufacturing of rc cars in 1980 in the Netherlands, Europe and has expanded the rc car program ever since !  Serpent has won mulitple World Championships, as well as European, American and Asian Championship titles. Michael Salven is head of design for all onroad Serpent cars, as has been racing all his life, and won World and European Championship titles, as well as many German national titles.   His experience and knowledge has also been used to design the Natrix 748.

Michael Salven as chief designer, developed this Natrix 748-e based on the Worlds TQ and Vice Champion Natrix 748 GP kit together with Nacho Lopez.

Main advantages of an electric 200mm car are:

• 200mm is more stabile and easier to be fast than with 190mm
• Very suitable also to use on larger 1/8 scale gastracks
• Use of wider foam tyres, makes racing easier, and no need for tyre oil
• Can handle both 2S and 3S battery packs, use 1/10 or even 1/8 speedo.
• Very strong and durable , as based on front and suspension  of the heavier 1/10 scale gascars
• Good range of optionals
• Good range of bodies and tyres, even better when you race 1/10 gp too
• Silent  but very fast, so ideal for rc tracks that dont allow GP cars (after certain hours).

PROMOTIONAL VIDEO FOR THE 748e:

CHASSIS:

Symmetrical chassisplate  for even flex and torsion in 3mm carbon fibre, lowered where the motor mounts as low as possible in the car.

TOPDECK:

The 2mm carbon fibre topdeck connect the front and rear suspension.

BATTERY HOLDERS:

The battery holders are in carbon fibre and have sleeves to enable use of battery mounting taope easily.

748 SERVO HOLDER:

MOTOR / MIDSHAFT / ANTI-ROLL BAR HOLDER:

the motor is mounted on a low strong aluminium holder, which doubles as mid-shaft holder and rear anti-roll bar holder as well.  

The mid-shaft mounts in 2 seperate holders with the ballbearing inside to enanble a fast and easy change of gears. 

FRONT BUMPER AND BODYMOUNT:

Front bumper with aerodynamic effects and excellent protection. Some parts of the lower bumper can be cut open to create more steering.  Medium or small foam bumper pad scan still be fitted as optional.  The upper carbon fibre bodyplate mounts to the front bumper with alu post and secures the front bdyposts

SUPERSHORT RCM SHOCKS:

Coated threaded shockbodies in high quality aluminium.  Supersmooth o-ring / bushing package, to guide  and seal the spring-steel piston rods. Precision moulded 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 shockabsorber springs with color coding. 

STEERINGBLOCKS:

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

WHEELAXLES/CVD'S:

The spring-steel wheelaxles are seated in high speed bearings. The light and durable  spring-steel cvd’s bring all the power to the front wheels. Wheels are mounted to orange anodised high grade aluminium hex-adaptors using flanged wheelnuts.

ANTI-ROLLBAR FRONT:

The ballraced wire type  anti-rollbar in the front is really easy to access and change for other type or thickness as needed.  The anti-roll bar is linked to the lower a-arms with a unique pivotball/cup system, which provides direct and smooth operation and is easy to set and adjust.

SHOCKTOWER FRONT:

Superlow 3.0mm  carbon fibre shocktowers with 3 positions for upper shockmounting. In the centre you can mount the 3rd bodypost as needed.

FRONT BRACKETS:

A compact and superlight structure of topquality aluminium parts consist of top-brackets, L and R equal bearing brackets, lower suspension bracket front. The open style design allows for very fast parts exchange as needed, like belt, diff or anti-roll bar.

SUSPENSION FRONT:

Strong long double A-arm suspension with aluminium pivotballs, which pivot in light nylon cups. Hard type composite arms.  The arms pivot on the inside on springsteel pins. The pivot-inserts are used to change rollcenter. Small grubscrews mount in the upper bracket to control downstop. Easy to access and change ride height, front width, toe-in, caster and camber.

SERVO-SAVER/STEERING:

The new lowered centraly mounted steel servo-saver post fits the spring-loaded ballraced servo-saver system and steering. The inserts allow 2 ackermann settings. Due to the open design the linkages with L/R threading can be reached easily. The whole system allows for very precise steering and minimum bumpsteer.

SUSPENSION REAR:

Rear brackets
Very rigid but open rear end design with a composition of machined alu brackets, allowing for easy maintenance. The differential brackets, L and R equal, are toothed and seat the excentric bearing holder, which allow for setting belttension. Its very quick and easy to mount a differential and or replace a belt. The machined aluminium lower suspension brackets have roll-center inserts with 3 positions to choose from.  The rear bracket is the narrow V1 version.

ANTI-ROLLBAR REAR:

The ballraced wire type  anti-rollbar in the rear is really easy to access from the top and change for other type or thickness as needed.  The anti-roll bar is linked to the lower a-arms with a spring-steel rod.

REAR BRACKETS:

Very rigid but open rear end design with a composition of machined alu brackets, allowing for easy maintenance. The differential brackets, L and R equal, are toothed and seat the excentric bearing holder, which allow for setting belttension. Its very quick and easy to mount a differential and or replace a belt. The machined aluminium lower suspension brackets have roll-center inserts with 3 positions to choose from.  The rear bracket is the narrow V1 version.

REAR CARBON SHOCKTOWER AND CAMBER BRACKET:

The low 3.0mm carbon shocktower has 3 upper mounting position for the shocks and it mounts the body-posts. The camber bracket offers 8  positions to choose from, 4 inner and 4 out holes.  The shocktower is prepared to mount the extra body-protectors, which are optional.

GEAR DIFFERENTIALS:

Compact, durable and lighter gear differential. Precision moulded steel gears, 2 small 14T and 2 large 28T ones.  The very durable and light spring steel lightened diff-adaptors connect to the driveshafts.  Front and rear geardifferential share the same internal parts

LOWER REAR WISHBONES:

The hard composite lower wishbones feature a mounting position for the anti-roll bar linkage which moves the link position more outside. Its also offers a mounting position for an optional carbon shock-mount bracket, to move the lower shockmount position further out, but for the default  set-up  its not needed. By placing the lower shock further out, you will get even more steering . 

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.  Rolll center chnages 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.

WHEELAXLES and DRIVESHAFT:

The durable spring steel wheelaxles combined with spring steel driveshafts bring the power from the gear-diff to the wheels.  Wheels are fitted on high grade anodised alu wheelhex adaptors and secured with flanged wheelnuts.

CVD DRIVESHAFTS:

Spring steel, light and very durable CVD’s used in the front. Precision mounted hard steel pins

DRIVE-SHAFTS:

Spring steel, light and very durable dogbones used in the rear. Precision mounted hard steel pins

PULLIES:

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

BELTS:

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