PLEASE READ THIS BEFORE
YOU BEGIN
We feel that our instruction manuals are the best in the
hobby. This is due to the number and quality of photos plus the
written information that explains each assembly. While it is
possible to assemble your kit only from the photos, we do not
recommend this. There is important facts or tips in the written
instructions that will help you to assemble your car for its best
performance and to prevent any delays due to assembly errors.
On road cars, while easier to assemble are more sensitive to
improper adjustments. So if you want to make your car the best
assembled car possible you will follow both the photos and
written instructions.
STEP 1 Open each parts bag when the instructions
indicate, not before. This is to help prevent parts from one bag
getting mixed up with parts from another bag. This kind of
mistake will cost you time and frustration while assembling your
car.
STEP 2 Check each parts bag for supplementary
instructions. Associated is always working on new designs
and materials to improve our products. This means that we will
occasionally make updates or changes to our kits. These
changes cannot be made immediately to the manuals, so we
use supplementary instructions to note changes. 1) Inspect
each bag upon opening it for the first time. Look for any pieces
of paper than have part and drawings showing what is being
changed. 2) When you do find one, locate the section of the
manual and parts list where these changes apply. 3) Note the
parts changes on the parts list then attach the supplement to
the appropriate assembly step in the manual. This will help
prevent delays in looking for the incorrect parts. It will also
reduce the chance of losing time taking something apart that
was assembled incorrectly due to use of the wrong parts.
STEP 3 Keep your parts separate. While building your car
it will be necessary to have more than one parts bag open at a
time. In order to prevent confusion we recommend using large
paper plates (especially picnic plates with partitions) to keep
parts from each bag spread out so that you can find them easily.
Mark each plate with the bag number or description before you
place the parts in them. When you have used all the parts from
one bag. You can then re-label the plate so that it can be used
for another bag.
STEP 4 Additional items needed to operate your car:
2 channel R/C, surface frequency, radio system (only one
servo is required). Because of limited space a small size
servo is recommended.
Battery pack (6-cell) needs to be assembled into a saddle
pack layout.
Battery charger, (we recommend the use of a peak
detection charger).
Electronic Speed Control (also referred to as an ESC).
R/C electric motor (will accept both stock and modified
motors).
Pinion Gear (48 pitch); size to be determined by type and
wind of motor you will be using.
FIRST, A WORD
ABOUT THE NEW RC12LC
CONGRATULATIONS!! You have purchased the pro-
duction version of the car that Masami Hirosaka used to win the
1996/97 IFMAR 1/12 scale On Road World Championships.
This latest generation of the RC12L series car gives you more
improvements and features to enhance your performance.
Associated started in electric R/C with the original RC12E
which won numerous National Championships. This progressed
into the RC12I which won the very first 1982/83 1/12 scale
IFMAR World Championships held in Anaheim, California. It
then won the next 1984/85 IFMAR World Championships held
in Denmark. The RC12L, the next generation, dominated the
1986/87 Las Vegas, Nevada World Championships by taking
1st through 5th as well as Top Qualifier honors. This car was
again used to win the 1988/89 World Championships in Baarn,
Holland.
For the 1990/91 World Championships, in Singapore,
we redesigned the RC12L. The RC12LW as it was known, won
the 1990/91 Worlds and backed that win up by winning the
1992/93 World Championships in Grand Rapids, Michigan. We
then added our Dynamic Strut front suspension. This was given
the name RC12LS. It was also the car to own until we won the
1996/97 Worlds with your new RC12LC. The designation
RC12LC stands for Cliff Lett who designed the car.
The proven features that come with the RC12LC
include our Dynamic Strut front suspension (with our optional
caster change feature), Delta shock, Assoc. II rear axle assem-
bly, and dished one piece wheels. The new rear axle allows you
to change the right wheel without having to readjust the diff
each time. To go with these successful features, Cliff Lett and
the rest of our design team have relocated the dampener pivot
post for more consistent performance. You also have damp-
ener inserts to limit roll movement for quicker directional
changes. We added a front suspension cross brace and used
a new front suspension material. This makes the front suspen-
sion more rigid and more precise. The batteries were moved
closer to the centerline, and a fiberglass roll over antenna was
added to the new light weight antenna/shock mount. A new rear
chassis brace and symetrical T-bar were designed and a
graphite T-bar brace was added. It also comes with a new
precision lightweight left rear bulkhead for accurate bearing
alignment. The redesigned upper and lower pod plates along
with the left bulkhead make it easier to install, remove and
solder in the motor. What you end up with is a car that is easier
and faster to get dialed in to the track conditions. The 1996/97
IFMAR Worlds was the first race for the new 12LC. How did it
fare? In the A-main the 12LC finished in the top five positions
and took seven out of ten places. Your new car will show you
why Associated has won all but one of the 1/12 IFMAR World
Championships ever held!!
