EXPLODED VI EWS AND PARTS LIST
Serpent developed the S120 PRO model car for demanding racers in the
highly competitive electric 1/12th scale pan car market, which like all our
previous cars, has been designed to win straight from the box.
Featuring a number of very effective features such as a fully adjustable front
end, machined aluminium rear pod, side-links combined with ball-link tube-
system to control chassis roll and grip, top-mounted shock-absorber, quick and
easy tweak adjustment and PRO quality materials throughout, the S120–PRO
should see you in the winners circle in no time. In fact everything associated
with this car is of the highest quality, from the packaging and supplied manuals,
right through to the product and race support.
Serpent’s long tradition of excellence extends to the instruction manuals, and
this instruction manual is no exception. The easy-to-follow layout is richly
illustrated with 3D-rendered full-color images to make your building experience
quick and easy. Following the instructions will result in a well-built, high-
performance race-car that will soon be able to unleash its full potential at the
racetrack.
The kit includes bags, with bagnumbers, which refer to the same step in the
manual. Open only the indicated bag(s) per step and finish that part of the
assembly. Remaining parts will be needed lateron in the assembly process.
In certain assembly steps you need to make basic adjustments, which will give
you a good initial setup for your Serpent S120–PRO. Fine-tuning the initial setup
is an essential part of building a high-performance racecar like yourS120–PRO.
The exploded views and parts lists for the Serpent S120–PRO are presented
in the Reference Guide section in the back of this manual. The exploded views
show all the parts of a particular assembly step along with the Serpent part
number. The parts lists indicate the part number andname of each part for
easy reference when ordering.
Serpent has made a strong effort to make this manual as complete and clear
as possible. Additional info may be published in our website: www.serpent.com
