Low-mounted 75cc fueltank with bronze sintered filter with new cap, moved more
to the front and offers a mounting-position for AMB transponder on the bottom.
Small side indent to provide space for the throttle lever. Tank-inserts can
be screw-mounted inside to decrease the contents if needed.
Tanks mounts on 3 alu posts, with rubber covers, capped with silicone o-ring
and small clips.
Asymetric roll bar with integrated sleeve for the fuel-cap strap. The roll bar
doubles also as end-stop for the fuel-cap, to prevent the cap to open too far.
Machined alu pipe-mount holds the spring-wire , which is attached to the radioplate.
Grub-screw holds wire in place.
The innovative and nice looking new bumper sports a split type foam bumper,
and the angled upper bumper creates a very sturdy front end, to absorb the impact
of crashes ( if any). ( A wider foam bumper is provided as optional.)
Ball-raced servo-saver design, with the steel servo saver shaft mounted on the
chassis only, spring-loaded with pre-tension nut and easy inserts to change
Ackermann. The linkages to the steering-servo are short and angles are smooth
/ direct and easy to access, as mounted above the radioplate.
Combined with the ultra strong SS-steel trackrods and smooth ball-joints, the
assembly creates a very effective and responsive steering-system.
New gear-ratio combined with new pullies with small sideholes to let dirt out
easily. Friction free and very smooth operation.

The middle shaft holder is beautifully integrated in the front left alu bracket
and secured with 3 screws. This offers strong, flex-free guidance to the SS-steel
2-speed shaft brackets
The 2 alu brackets to hold the 2-speed shaft are true works of art. By separating
them from the rear end brackets, it creates lots of open space to work on the
car and gives better way for cooling too. In the top the brackets support the
ball-raced rear anti-roll bar, which is seated in the brackets with small steel
adaptors and high speed bearings. The left one also houses the ball-raced brake-cam
and supports the chassis stiffner too. Multi-functional.
4mm thick carbon fibre rear shocktower with 6 mounting positions for the shocks.
The holes are positioned in such way, that when changing to to another hole,
the length of the shocks can remain the same. The shocktower includes holes
to mount the tank-cap strap, as well as mounting positions for the rear body
New uprights to suit the new geometry. Allows for 2 mounting positions in the
top, inner or outer and the kit comes complete with conical spacers to change
The new rear lower wishbones can be used both left and right. The anti-roll
bar linkage has 2 mounting positions to choose from. The rear carbon camber
bracket in 4mm thick material , has 9 positions to choose from, 5 inner and
4 outer each side. The roll-center changes can be made by changing the inner
pivot inserts for a lower, medium or higher position, depending on the situation.
Wheel-base can be changed by using the casterclips in front or back of the wishbone
on the lower pin.
A very accessible and cool brake system. The brake-system is mounted very low
in the car for better center of gravity. Spring loaded race pads that slide
on precision machined bushings. The race brake-pads are ready to use with pre-baked
friction material ( no more glueing ) that lasts and offers incredible braking
power with excellent brake feeling / feedback. Reaches right temperature quickly,
has no fading and works well in the rain too. The nylon brake lever, that operates
the hard-anodised ballraced brake-cam, has 2 mounting positions for the linkage.
The linkage runs very straight to the servo-arm.
The very short and narrow radioplate is made of 2.5mm high quality carbon fibre
material and ads to the overall stiffness of the car. The overall design is
made in such way that the complete radioplate with tank, roll-bar, belt-tensioner
and all electronics comes out of the car in one go. Just release the steeringlever
and release 7 screws. Ideal for cleaning and maintenance. All wiring very short
and compact to mount. Straight aligned servo-linkages to both brake and throttle
Radio-gear and battery mounting
The 733 provides a neatly designed side-bracket-assembly that offers mounting
space for the receiver, the switch, the antenna and both servo?s. The receiver
goes into the nylon box with embossed Serpent logo. On the opposite side of
the tank, the battery ( Lipo or regular pack) is mounted to a carbon fibre bracket
(shrink-foil/tape) , which again mounts to the radioplate with nylon spacers.
This very compact design means you can use very short cables and when mounted
correctly hardly any cables are visible from the outside, but house well protected
inside the car. The steering-servo bracket offers another mounting position
( 2 holes) for the transponder in case that is prefered instead of the lower
mounting position under the tank.
Spacers are provided to correctly mount the servos, as well as 3 types servo
levers to suit all major brands.
High speed stainless steel bearings throughout the car, lightweight and lubricated
with high quality Shell bearing oil. High quality one-way bearing for the 2-speed
Allen type high quality steel screw throughout the car.
Kevlar 4mm wide re-inforced drive-belts. Kevlar type belts are standard (the
black/brown low friction rubber type are optional) .
Driveshafts / wheel-adaptors
The front end has SS-steel CVD system, with laser engraved, ultra thin and light
driveshafts, combined with durable wheel-axles and precision machined alu hex
The rear end has SS-steel dogbones also thin/lightweight, yet durable, to stand
the beating of the ever increasing horsepower and grip-levels. The Direct Link
System (DLS) can be used as shown, but the camber bracket is universal, so you
can also run in standard format.
New geometry and roll-centers, lower center of gravity and modified weight-positioning
for improved grip and better balance.Adjustable caster, camber, toe-in, width,
wheelbase front and rear, ride-height, roll centers and more.
Front end brackets
Alu front lower bearing blocks and suspension brackets, with integrated anti-roll
bar holders and integrated alu middle bearing block. The gear-diff is seated
in eccentric nylon bushings to set the belt-tension. The right position ( choice
of 4) of the eccentric bushings can be recognised from the outside, for easier
re-assembly. The lower front end brackets have steel pins pre-mounted which
slide into the slots in the chassis, for precise positioning.
Very open design split type rear end assembly. The supersmall and light gear-diffs
mount very low in the car, in precision machined split type alu brackets. The
gear-diff is seated in eccentric nylon bushings to set the belt-tension. The
right position ( choice of 3) of the eccentric bushings can be recognised from
the outside, for easier re-assembly.
The lower rear end brackets have steel pins pre-mounted which slide into the
slots in the chassis, for precise positioning.
The very open design leaves lots of space for maintenance, cleaning and cooling.
The 3mm chassis is made of precision machined aerospace quality 7075 T6 alu.
Countersunk and with chamfered edges. Some extra machining where needed for
the belt, the engine with airscoop for cooling, for the flywheel and some extra
space to allow the moutning the transponder below the fueltank. The very closed
design of the chassis creates the right level of rigidity in the car. More flex-control
is offered with the alu stiffners on the chassis. Hard anodised chassis is optional.
Mono-type engine mount, for sucure seating of the engine. Extra coolingfins
for better heat-dissipation. The system allows for precise alignment of the
clutch and 2-speed gearbox.
Chassis stiffners and flex control
The main chassis-stiffner is the ball-joint rod which is mounted between the
radioplate and the left 2-speed bracket.
New front upper and front lower wishbones, made from superb M-type nylon materials
and have an excellent fit on the hardened steel pivot pins. The lower wishbones
houses the hard-coated alu pivot-ball, which operates the front anti-roll bar.
The wheelbase can be changed in the front by using the small caster-spacers
in front or back of the lower front wishbone. In the top ofcourse change caster
in the same way. The roll-center changes can be made by changing the inner pivot
inserts for a lower, medium or higher position, depending on the situation.
Front upper bracket
The nylon upper bracket, connect the front alu bearing blocks, holds the carbon
fibre shocktower and the upper hinge pin inserts and incorporates the downstops.
To take out the diff takes 4 screws only.
The kit comes with the strong prooven steeringblocks with off-set 0. Offset
1 is available as option. The steeringblocks mount to the wishbones with light-weight
coated alu 8.5mm pivotballs, and use the nylon ball-cups for an ultra light
and ultra smooth suspension process.
Anti-roll bar front
Ball-raced wire type front anti-roll bar system, more efficient and easier to
tweak. Operated by linkages that mount to alu pivotballs on the ower front arms.
2.5mm is standard, other options. 1.8, 2.2 and 2.8
Carbon fibre front shocktower in 3.2mm with 4 positions for the front shocks.
Includes holes to mount the 3rd bodymount.
Pre-assembled RCCX shock-sets. Short type both front and rear, also short springs
front and rear. With the 2009 modification on rod-support and silicone x-ring
for supersmooth shocks. SS-steel shock-rods, precision machined coated shock-housings,
foam bleeders, precision moulded nylon pistons and shock-parts. The spring pre-load
nut has a silicone o-ring inside to prevent unwanted change.
Use 1000 Cst (40W) shock-oil as enclosed for standard set-up both front and
Extremely small and light gear differential, seated as low as possible in the
733. The same gear-diff is used in the front and rear of the car, just different
pullies are mounted. High quality, precision machined , hardedned gears, combined
with SS-steel shafts, create a supersmooth gear-diff. The gear-cases are sealed
with a captured o-ring. The SS-steel precison machined outdrives are lightened
to decrease rotating mass further. For standard set-up use 80.000 Cst front
and 30.000 Cst rear oil, as provided.
Its very easy and fast to take the diffs out of the car.
The Serpent 733 comes with the famous Centax clutch ( an original Serpent innovation)
. The ultra reliable Centax III WC version comes with precison machined, hardcoated
alu screw on gears ( laser engraved) mounted on a hardened steel clutch-bell.
A very small and light 31mm hardcoated alu flywheel with precision mounted steel
pins. Race developed clutch shoe and flyweights, combined with a hard Centax
spring, to create a superb working clutch for amazing accelleration and durability.
High quality nylon ball-joints for precision fit on the pivot balls. All balljoints
of the car are on one larger frame inside the kit. Some have TOP as indication,
to show which direction to mount them for best operation.
Ulta smooth gear-changes are provided by the SL6 automatic 2-speed gearbox,
which combines perfectly with the Centax-3 system. New gears for SL8, new design/
shape, very durablePrecision machined 2-speed bell and one-way adaptor, combined
with durable centrifugal shoes mounted on the SS-steel polished adaptor. Balanced
SS-steel 2-speed layshaft.
