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

A800X car

is designed for use on r/c car race tracks. It should not be used in general public areas.

Awesomatix Innovations 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.

Awesomatix Innovations do reserve all rights to change any specifications without prior notice. All rights reserved.

INTRODUCTION

Congratulations on purchasing your Awesomatix car!

The A800X car was designed in Russia and produced by Awesomatix Innovations company.
The A800X car utilises many unique features, including some patented innovations.

GENERAL PRECAUTIONS

• 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.
Keep the wheels of the model off the ground when checking the operation 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.

ASSEMBLY NOTES

Before starting each build-stage check that you have the right quantity and size of items for the build-stage. To assist you with

the assembly of your

A800X car

we have included full-size images of all the small hardware parts laid out so that you can

place items on top of the images to check they are the correct size/length. You can find the useful tips and pictures of A800X

assembling on the Internet sites: www.awesomatix.info/en/tipps-tricks/aufbau/ , www.awesomatixusa.com/p/tips.html ,

Rebuildable Damper Set

AT40-1

Note: Every A800X kit includes four factory assembled and oil filled D2.2 Rebuildable Dampers. D2.2 damper allows for
both dampening adjustment via thicker silicon oil, and consistent performance since the racer can rebuild the shock.
The factory assembled and oil filled D2.2 Rebuildable Dampers come with 500 cst pure silicone oil inside.

The build instructions for D2.2 Rebuildable Dampers is on this page.

For disassembling please do all steps in the reverse order.

1) Stretch and place OR18 O-ring in the groove of the AT40-1 Cup.

2) Insert P45L Sponge Piston into AT41-2 Vane cavity. Align the outer face of P45L Piston with the outer edge of AT41-2 Vane cavity.

3) Stand AT42-1 Case up and fill ~1/2 of volume with the desirable silicone oil. Insert AT41-2 Vane into AT42-1 Case slowly full way down.

4) Add more silicone oil. Oil should cover the AT41-2 Vane completely. It is highly recommend that damper be placed into a vacuum pump

to remove air. Otherwise let the damper sit for 30m+ to allow air bubbles to escape.

5) With the damper still vertical (important !), screw AT40-1 Cup into the AT42-1 Case with a 9mm socket wrench until fully threaded. Do
not force the AT40-1 Cup - once aligned, it will screw on easily. The excessive oil should go out through the gap between AT40-1 and

AT41-2 Vane. Please don’t remove this oil from the bearing cavity of AT40-1 Cup on this stage!

6) Place OR155 O-ring into AT40-1 Cup. You can use a piece of an appropriate tube to press o-ring slowly and fully into cavity.

7) Place B85 bearing and one SH5X7X0.1 shim onto AT41-2 Vane output shaft.

8) Clean up oil off the outer surface of damper.

SUSPENSION SETTING TECHNIQUE

Camber adjustment rule: Simultaneous both upper rods

0.5mm shortening (1/2 turn of both turnbuckles) adds 1.0°

of camber angle at constant caster.

Caster adjustment rule: Simultaneous front upper rod

0.5mm elongation and rear upper rod 0.5mm shortening
adds 2.5° of caster at constant camber.

Wheelbase adjustment:

Use rear suspension caster change for this adjustment.
Adding 4°caster shortens wheelbase by 1mm.

Use Ride Height Gauge for Upstop
& Downstop measuring.

Reactive Caster setting is possible.

Use SS3X4 screws
for Upstop and
Downstop setting.

Roll Center adjustment:

Use combinations of SH0.5, SH1.0 and SH1.75 Spacers
under appropriate Pivot Balls and Ball Studs for
this adjustment.

Adjust these spacers for
Bump Steer control.

Caster measuring:

Caster angle° =

(H1-H2)*1.5 for front
(H1-H2)*2.2 for rear

SHOCK SETTING TECHNIQUE

2. Shock Spring preload setting

Turn IN (CW) RHS Screw to increase spring preload.
Turn OUT (CCW) RHS Screw to decrease spring preload.
Use Spring preload setting to adjust Ride Height value.

1. Damping and Shock Spring rate setting

Increase A-distance (slide Shock outward) to increase

Damping and Spring rates simultaneously and

concordantly to each other. A-distance range is 0 - 4.4mm.

Use outer SF3X10 Flat Head Screw to unlock Shock and
to lock it at desirable position.
Decrease B distance (slide P09 Shock Screw Holder outward) to
increase Spring rate only at the fixed Damping rate value.
Use SRS Spring Rating Screw to unlock Shock Screw Holder and
to lock it at desirable position.

Attention! These Shocks allow to adjust
the Damping and Spring rates without
replacement of the shock’s fluid and spring.
