The S120 LTR Pancar EP produced by Serpent in 1/12 scale Pan Car series RWD drivetrain assembly kit, is classified in R/C Models - On-Road - Pan Cars
Serpent 1/12 scale pancar S120 LTR version. High performance 1/12 scale pan
chassis, with nicely machined carbon fibre and aluminium parts. Superb fully
adjustable front end creates loads of steering. Spring loaded Link system, in
combination with diagonal positioned main shock and tube-system, controls the
roll of the car. Well balanced Lipo chassis offers wide selection of set-up
features and options to dial the car in best for any track.
- Class: 1/12th scale

- Innovative rear-central pivot system which connect the rear pod in new way
with the chassis, and thus prevents any binding, creating more effective sidelink
action, at any angle. With this changing roll-center is also very easy.

chassis in new shape to allow for new rear pivot and flex dynamics
- Side-springs can now be used in outer or inner position

The S120 Link chassis consists of 2 main elements, the 2.5mm thick carbon fibre
chassis plate and the rear aluminium-carbon motor pod. The chassis uses a Link-system
, and is damped using a conventional centrally mounted shock absorber together
with an anodised tube system.
The front end of the car is completely adjustable and utilises the now standard
fixed lower suspension arms combined with top wishbones, which together with
kingpin mounted springs ensure that the car is able to corner at high speeds
and soak up any small bumps found on the racing surface.
The front end of the car features many different adjustments to help you get
the most from your car, all of which are easy to adjust and measure. Fixed lower
suspension arms are themselves damped by the central strut which uses rubber
o-rings to take up the flex in this area, while the grey anodised aluminium
front upper wishbone mounts are available in different caster angles, the car
being supplied with 9 degree versions as standard. Ride height spacers are available
too in 0.5mm and 1mm. With the steering block king pins spring loaded, the cornering
forces are channelled through the upper wishbone, which enable the car to corner
at high speeds.
The new steeringblocks and upper arms are strong and easy to adjust. The king
pin inclination is easily changed by using different inserts.
The S120-LTR uses tubes to controll the roll of the car. This system plays
a big part in how the car turns into a corner which can be adjusted through
the use of different oils, 15.000 for normal grip and 20.000 for high grip tracks.
The springloaded side-bars, the links, are made of composite nylon and control
the roll of the chassis, together with the tubes and the main central shock.
The central section is a combination of elements to control the movements of
the rear end perfectly
- a central main shock, the shocktower enables various angles.
- the anodised alu tubes on both sides
- 2 spring loaded shaped side bars
These elements interact to create the best possible handling (roll, bump and
alignment) under all grip-conditions.
The side spring scan now be mounted in an out or inner position depending on
set-up and grip-levels.
To aid rear traction under acceleration and to absorb bumps, the S120 LTR sports
a centrally mounted shock absorber. Supplied with a soft spring, the pre load
of which can be adjusted, the front mount of this shock absorber is used for
adjusting the rear down stop and range of movement between the chassis and motor
pod. The shockabsorbers uses an internal foam element. A variery of pistons
and springs are availbale as options.
For securely mounting the body shell to your S120 LTR the car has strong plastic
body posts front and rear. All 4 posts are supplied with orange anodised adjustable
collars to precisely adjust the body's height and the posts are supplied extra
long to allow the user to cut them to their own preferred length. The front
body posts have also been designed to help protect the front of the carbon chassis
from splitting in the event of a heavy front impact.
The S120 LTR comes supplied with a high quality miniature servo saver, which
through the use of orange anodised shims, has adjustable Ackerman.
The kit includes 2 alu servo posts,with eccebtric holes which together with
the slide in the chassis, enable a perfectly centered mounting of any popular
The small foam bumper is also included.
The lightweight alu rear axle is mounted on bearings that sit within eccentric
composite inserts that allows the user to quickly and easily change the rear
ride height of the car simply by changing between inserts.
The kit comes supplied with all 9 inserts which range between 0 and 4mm, each
differing by 0.5mm and all are reversible for an even wider range of adjustment.
The S120 LTR comes supplied with a durable and high performance ball differential.
Easily adjusted by a plastic nut, accessible through the right rear wheel, the
diff uses high quality steel balls and plates and is supplied with both suitable
silicone and graphite grease for use during assembly and maintenance. The rear
diff features hardened D-plates and light alu shaft assembly for super smooth
The strong basis is formed by the 2.0mm thick carbon fibre chassis plate designed
such way that the Lipo can be mounted in lateral direction, and can be mounted
either left or right side or across in the back, and still enough space for
all the valuable electronics.
The alu / carbon motorpod is a beautifull combination of high quality machined
alu brackets and top quality carbon fibre parts, bolted together to create an
ultra stiff rear pod. The new motor-bracket allows the brushless motor to be
mounted in the optimal position for car balance and offers good heat dissipation
as well . The motorpod brackets are lighter and lower to reduce LG even further.
The new innovative pivot-system which connect the rear pod with the main chassis
allows for full free movement of the 2 main parts, thus avoiding any binding,
enabling the side-links to work optimally. With small shims the ride-height
can be easily changed.
