building R/C model racing cars.
This is not atoy and is not intended for use bychildren without direct supervision of a responsible, knowledgeable adult.
Read the instruction manual carefully and fully understand it before beginning assembly. If you have any problems or
questions please do not hesitate to contact the Awesomatixteam at [e-mail]. If,for any reason,you
decide that you do not want your A12car you must not begin assembly.
Your A12car cannot be returned to UAB Awesomatix for a refund or exchange if it has been fully or partially assembled.
This kit is a radio controlled model racing product and could cause harm and personal injury.
The A12car isdesigned for use on r/c car race tracks. It should not be used in general public areas.
UAB Awesomatix accept no responsibility for any injuries caused by making or using this kit.
Due to policy of continuous product development the exact specifications of the kit may vary.

INTRODUCTION
Congratulations on purchasing your Awesomatix car!
The A12car was produced by UAB Awesomatix company.
GENERALPRECAUTIONS
•Many of the items in this kit are small enough to be accidentally swallowed and are therefore potential choking hazards, making them potentially fatal.
Please ensure that when assembling the kit you do so out of the reach of small/young children.
•Take care when building, as some parts may have sharp edges.
•Please read this manual carefully to understand which ancillary items (tools, electrics, electronics etc) are used with this kit.
Awesomatix Innovations accept no responsibility for the operation of any such ancillary items.
Exercise care when using tools and sharp instruments.
• Follow the operating instructions for the radio equipment at all times.
•
• Never touch rotating parts of the car as this may cause injury.
Keepthewheelsofthemodeloffthegroundwhencheckingtheoperation of the radio equipment.
• To prevent any serious personal injury and/or damage to property, be responsible when operating all remote controlled models.
• The model car is not intended for use on roads or areas where its operation can conflict with or disrupt pedestrian or vehicular traffic.
•
• Do not run your car in poor light or if it goes out of sight. Any impairment to your vision may result in damage to your car or, worse, injury to others
or their property.
• As a radio controlled device, your car is subject to radio interference from things beyond your control. Any such interference may cause a loss of
control of your car so please consider this possibility at all times.
When not using RC model, always disconnect and remove battery.
• Insulate any exposed electrical wiring to prevent dangerous short circuits.
•
Take maximum care in wiring, connecting and insulating cables. Make sure cables are always connected securely.
Check connectors for if they become loose and if so reconnect them securely. Never use R/C models with damaged wires.
A damaged wire is extremely dangerous and can cause short-circuits resulting in fire.

Note:Add ~0,3g of50 000...100 000 cst silicone oil
into cavity of ST1204 damper case.We recommend
100000 cst silicone oilas the base setup.
Keep ST1204 upright for several
minutes until all oil reaches
the bottom of the cavity.
ST1204
Note:Insert ST1202 damper rotor into ST1204damper case slowly.
After the lower face of the ST1202reaches the oil in the bottom of the cavity, the
ST1202will need an additional force to be pushed fully into the proper position. We
recommend using a rubber band or OR230o-ring as shown in the picture. The oil will
start to come up towards the top of the cavity of the ST1204as the ST1202is pushed
further into that cavity by the o-ring. When the OR153Vo-ring and the ST1204damper
are close to flush (almost fully inserted), please use a sewing needed or a sharp pin
along the recess of the ST1202to move the o-ring out of position and allow more oil to
be pushed out from the ST1204case. Using this needle or pin will allow the ST1202to
be fully seated and sit perfectly flush with the ST1204damper case.

SH12S-0.20.2mm thickness shims are used to set the
front spring preload and the front ride height.
The front damping of the steering blocks
is adjusted via:
1) Number of the o-rings installed (0,1 or 2).
2) O-ring’s preload by SH0.1 6x8x0.1mm shims.
3) Lubricant for o-rings.
4) Amount and viscosity of the damping fluid
inside the steering blocks.

with different oils or
greases.
OR155SI x0..1As initial setting we recommend to
use only one lower OR155SIoring
lubricated by joint grease without
preload by SH0.1 shims.
Another option is to use no orings
and only thick grease on the
ST1207 in the steering blocks,
depending on track conditions.

Attention!When installing SH12S0.2 shims,make
sure they surround the ST1207but not below or
above the ST1207end faces.

measuring within 4.0 - 5.2 mm range.
“+1,5” RHG Spacer position for ride height
measuring within 4.5 - 5.7mm range.
RHG4.2gauge is designed for setting and measuring the ride height under rear damper of the
A12car (DRH-Damper Ride Height) and can bealso used for setting and measuring of the front
ride height (FRH) and the rear ride height (RRH).
RHG4.2gauge provides a 3.0- 4.2mm range for ride height measuring without ST1215 spacer.
With ST1215 spacer the gauge provides a 4.0- 5.2mm and 4.5- 5.7mm ranges (positions “+1”
and “+1.5”of ST1215 spacer).
TheDRH- ride height under rear damper measuring.
TheRRH- rear ride height measuring.TheFRH- front ride height measuring.

Setting oftheDRH-therideheightunder rear damper.
The ride height under rear damper (DRH)is set via preloadof two side coil springs SPR12Sin
conjunction withtheoptional additional preloadvia set screws in the two sidebeams AM1205.
These beams act as springs when the screws in them press on the AM1204chassis plate.
A12setupsheet includes two values forthe rear ride height. DRH1shows the ride height resulting
from side spring pressure only, without the use of AM1205side beams. DRHride height is the final
ride height of the car (which can be a combination of both side springs and side bars to reach this final
desired height). For example, DRH1 (damper ride height set with only side spring pressure) will equal
DRH when side beams are not being used, as there is no additional side beam pressure.
Setting oftheRear Droop.
AM1205 side beams act as an additional spring when these set screws are set to touch
the AM1204 outer plate. The rearmost position of the set screws provides the stiffest
vertical suspension rate, and the front most position the softest vertical suspension rate.
These side beams can also be used without any set screws for a small increase in the
cars overall vertical stiffness. Please use blue “Soft” thread lock on any set screws used.
Adjusting of SS3X10 set screw depth (DroopScrewDepth)
is used for setting of the rear suspension droop (RearDroop).
DroopScrewDepth can be measured via calipers or via
counting of the number of turns the screw is screwed into
damper’s case. Every turn of the thread is 0,5mm in depth.
So for example, 4full turns of SS3X10 screw starting
from position when the lower face of the screw
coincides with the lower face of the damper
corresponds to 2mm DroopScrewDepth.
Enter DroopScrewDepthvalue into the
A12editable setup sheet. The rear droop
value will be calculated automatically based
on the DRHand RRH data.

When using big tires,youwill needto use shimsunder theC1205 to obtain the
desiredrideheight. Placing shimsunder thesteering block will not besufficient
