Front bumper and Body mount
The bumper plate is made from a high-quality composite that is impact resistant.
This is all protected by the low profile foam bumper which can withstand huge
impacts and still protect your car. The front bumper mount is also the mounting
point for the front body posts.
The nose block ensures that the downstop settings are not altered by impacts.
This piece also doubles as a neat personal transponder mount.
Front anti-roll bar
The front anti-roll bar uses the effective blade system. The mounting levers
are used to adjust both upstop and downstop settings.
Steering Blocks Evo 2
Supplied with the 720 '09 kit are these Evo2 steering blocks, which are supplied
in 2 sets with 0 and 1mm kingpin angle. These new blocks have 1mm more offset
compared to the standard versions, which gives the car a more smooth steering
style. The 0-degree blocks work well on medium traction surfaces while the 1-degree
blocks work better on low to medium level traction surfaces. However if you
swap the left and right 1-degree blocks, the car will then work better in high
grip tracks, actually reducing the effects of grip roll, while at the same time
giving the car smoother, more consistent, cornering.
Composite servo saver for the Serpent 720 with optional Ackerman inserts.
Servo Saver with adjustable Ackerman
A direct replacement of the original servo saver, this new version allows the
user to easily adjust the cars Ackerman through the use of inserts thus eliminating
the need to remove the entire assembly. Users can now find the most suitable
setting by easily switching between the 4 different Ackerman settings now available
Spring steel driveshafts
The 720 '09 comes supplied with the finest Spring Steel drive shafts capable
of withstanding constant punishment; these shafts are ultra durable and very
stiff allowing you to put all your power to the tarmac. The rear of this car
uses dogbones while the front uses the supplied CVD shafts.
Aluminium Pivot Balls
The ultra-lightweight but very strong aluminium pivot balls provide a huge weight
saving over the steel versions without compromising strength, and we have provided
them as standard.
Adjusting nut for pivot balls
These new adjusting nuts are made from Nylon and replace the previous aluminium
nut with plastic insert which will not only makes assembly easier, it also reduces
unsprung weight. Reducing the parts used at this point also reduces side play
so it makes for a more precise handling car and because the material used is
self-lubricating the movement of the pivot ball will remain smooth throughout
The car also comes supplied with orange anodised aluminium hex wheel adaptors
that ensure that flex is eliminated in the drive train when under strain.
The chassis plate, made of aerospace quality 7075 T6 alu has now been clear
anodised and features a machined recess to mount the supplied front brass plate,
an option that helps remove snap oversteer and allows the car to corner faster
and smoother. This 4mm thick aluminium plate features countersunk screw holes
along the bottom to ensure that no screws come in contact with the ground. The
chassis also features chamfered edges to give greater clearance when going over
curbs or when running low to the ground, chassi has been recessed in all area;s
for lower center of gravity, LCG.
To keep the centre-of-gravity as low and as centralised as possible, the chassis
also houses the car's battery pack.
Serpent has included an improved version of their 75cc fuel tank in the 720
'09 which has been made from a newer stronger material. The milky white coloured
tank will now have more resistance to shattering in the event of a heavy impact.
The tank is top-mounted using rubber-covered aluminium mountings to isolate
the tank from vibrations, and small body clips allow for quick & easy removal.
Improving on the concept that Serpent pioneered, their famous AFL fuel tank
lid has been updated once more. Made from rubber, the new seal (softer silicone
rubber) has been shaped to create a perfect seal around the opening of the tank
and allowing the tank lid to close fully.
Rigidity is important in a modern day chassis, and this car is no exception.
Sporting graphite side plates, a technology that Serpent pioneered, this car
is ultra stiff and allows the shock absorbers and suspension components to work
more effectively by reducing unwanted chassis flex.
The left chassis stiffener also doubles as the mounting point for the side
Alu X-Bracket and Single piece motor mount
An aluminium radio plate X bracket also comes as standard, that not only looks
great but also helps increase rigidity of the car, while finally, to ensure
the engine mounting points are kept aligned, reducing stress on the crankcase,
the 720-09 is supplied with the single piece orange anodised engine mount.
High Res pic - Exhaust mounting spring
Exhaust mounting spring
The exhaust mount is a spring-type mounting wire that isolates vibrations. The
wire mount is attached to the radio plate by a mounting post and secured in
place with a set screw.
The rear end of the Serpent 720 '09 features strong 1-piece lower wishbones
and fully adjustable uprights. As with all the wishbones on the car, the lower
wishbones can be used on both the left and right sides, minimizing the number
of spare parts needed to bring to the track. The rear upright features robust
pivotball mounting points on the bottom and two upper camber link mounting holes
for fine-tuning rear roll centre.
Rear anti-roll bar
The rear anti-roll bar for the Serpent 720 is ball-raced for extra precision.
Stiffness is quickly and easily adjustable by changing the linkage mounting
points on the lower wishbones or alternatively by changing the position of the
ball joint pivot point on the roll bar itself.To further stiffen the rear end
of the car, we have created a distinctive S-shaped carbon brace which spans
the two rear bearing blocks.
Rear upper wishbone
The Serpent 720 continues to use an adjustable linkage as it has proved to be
solid and lightweight, easily handling impacts, while offering improved and
simple adjustment. The two inner mounting positions of each camber link offer
an easy way to adjust camber rise.
Precision machined disk brake, due to its excellent cooling characteristics,
this ventilated brake disk allows smooth and precise braking. Its also very
lightweight and is also very cool looking. Simple and effective stopping power.
The 720's braking system has been race proven and comes with a single ventilated
brake disk to further improve braking performance and consistency.
Rear body mount
The simplicity of the rear end of the 720 means it is possible to remove the
rear axles with only 6 screws. This configuration also makes it very easy to
adjust the rear lower roll centre positions. Another great feature of the rear
end is that the body mounting posts are no longer mounted directly to the carbon
shock tower but are instead mounted to a flexible composite body mount plate.
This reduces the chance of shock tower breakage even in large accidents.
The supplied gear differentials give smooth differential action and high durability,
and gear slippage is non-existent due to the geared design. Performance and
tuning characteristics are easily adjusted via gear oils of different thicknesses.
As an added extra, the Serpent 720 '09 comes with the previously optional front
one way system as well the one way lock set to make it into a solid axle, ensuring
your car will be ready for all conditions.
Centax clutch III
Ofcourse the Serpent invented Centax clutch is also incuded in the Serpent 720.High
quality gears, strong and durable clutch-housing, combined with shaped clutch-shoe
plate, high grip red shoe and best quality hardware.All the punch you will possibly
The 720 '09 comes with a new smaller diameter flywheel but continues to use
the same lightweight and well-tested transmission as in previous versions. Featuring
a fine gear pitch and lightweight components, the result is better acceleration
whilst the race-winning Centax-III clutch system is easily adjusted and performs
RCC Shock Absorbers
The RCC shock absorbers are the smoothest and easiest to build shocks ever designed.
Machined from metal and unique in that the shock bodies only open on the bottom
half, they are really simple to assemble. They come with a fixed piston and
no longer use a diaphragm as with the previous shocks. The result is an ultra-smooth
and air-free shock absorber thanks to the self-bleeding system incorporated
into the design.
Another great benefit is that these shock absorbers come pre-assembled in the
kit, so you need only add shock oil.
Supplied with orange-sealed high-quality lightweight bearings throughout, the
drive train is very efficient and runs very smoothly.
Drive Belt System
The 720 '09 sports a now tried and tested drive ratio that makes it suitable
for all tracks. The car comes with 3 narrow, low friction Kevlar belts.
The Serpent 720 has been designed with the highest level of competition in mind
and is therefore fully adjustable. The racer can change numerous settings easily
and effectively, including the suspension geometry. Upstops and downstops can
be easily accessed and easily adjusted for optimum handling, as can the cars
roll centers at both the front and rear of the car. Castor, toe, and camber
are also easily adjusted.
The wheel axles are made from the highest quality steel. Sporting a threaded
shaft to mount the wheel, these parts are built to last. The 720 '08 comes with
2 rear wheel axles made for dog bones whilst the front drive shafts make up
part of the supplied CVD system.
