IMPORTANT NOTES – GENERAL
• This product is not suitable for children under 16 years of age without the direct supervision of a responsible and knowledgeable adult.
• Carefully read all manufacturers warnings and cautions for any parts used in the construction and use of your model.
• Assemble this kit only in places away from the reach of very small children.
• First-time builders and users should seek advice from people who have building experience in order to assemble the model correctly and to allow the model to reach its performance potential.
• Exercise care when using tools and sharp instruments.
• Take care when building, as some parts may have sharp edges.
• Keep small parts out of reach of small children. Children must not be allowed to put any parts in their mouth, or pull vinyl bag over their head.
• Read and follow instructions supplied with paints and/or cement, if used (not included in kit).
• Immediately after using your model, do NOT touch equipment on the model such as the motor and speed controller, because they generate high temperatures. You may seriously burn yourself seriously touching them.
• Follow the operating instructions for the radio equipment at all times.
• Do not put fingers or any objects inside rotating and moving parts, as this may cause damage or serious injury as your finger, hair, clothes, etc. may get caught.
• Be sure that your operating frequency is clear before turning on or running your model, and never share the same frequency with somebody else at the same time. Ensure that others are aware of the operating frequency you are using and when you are using it.
• Use a transmitter designed for ground use with RC cars. Make sure that no one else is using the same frequency as yours in your operating area. Using the same frequency at the same time, whether it is driving, flying or sailing, can cause loss of control of the RC model, resulting in a serious accident.
• Always turn on your transmitter before you turn on the receiver in the car.
Always turn off the receiver before turning your transmitter off.
• Keep the wheels of the model off the ground when checking the operation of the radio equipment.
• Disconnect the battery pack before storing your model.
• When learning to operate your model, go to an area that has no obstacles that can damage your model if your model suffers a collision.
• Remove any sand, mud, dirt, grass or water before putting your model away.
• If the model behaves strangely, immediately stop the model, check and clear the problem.
• 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 public places and roads or areas where its operation can conflict with or disrupt pedestrian or vehicular traffic.
• Because the model car is controlled by radio, it is subject to radio interference from many sources that are beyond your control. Since radio interference can cause momentary loss of control, always allow a safety margin in all directions around the model in order to prevent collisions.
• Do not use your model:
- Near real cars, animals, or people that are unaware that an RC car is being
driven.
- In places where children and people gather
- In residential districts and parks
- In limited indoor spaces
- In wet conditions
- In the street
- In areas where loud noises can disturb others, such as hospitals and
residential areas.
- At night or anytime your line of sight to the model may be obstructed or
impaired in any way.
To prevent any serious personal injury and/or damage to property, please be responsible when operating all remote controlled models.
IMPORTANT NOTES – ELECTRICAL
• Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape) 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. Please have wires repaired at your local hobby shop.
• Low battery power will result in loss of control. Loss of control can occur due to a weak battery in either the transmitter or the receiver. Weak running battery may also result in an out of control car if your car‘s receiver power is supplied by the running battery. Stop operation immediately if the car starts to slow down.
• When not using RC model, always disconnect and remove battery.
• Do not disassemble battery or cut battery cables. If the running battery shortcircuits, approximately 300W of electricity can be discharged, leading to fire or burns. Never disassemble battery or cut battery cables.
• Use a recommended charger for the receiver and transmitter batteries and follow the instructions correctly. Over-charging, incorrect charging, or using inferior chargers can cause the batteries to become dangerously hot.
Recharge battery when necessary. Continual recharging may damage battery and, in the worst case, could build up heat leading to fire. If battery becomes extremely hot during recharging, please ask your local hobby shop for check and/or repair and/or replacement.
• Regularly check the charger for potential hazards such as damage to the cable, plug, casing or other defects. Ensure that any damage is rectified before using the charger again. Modifying the charger may cause short-circuit or overcharging leading to a serious accident. Therefore do not modify the charger.
• Always unplug charger when recharging is finished.
• Do not recharge battery while battery is still warm. After use, battery retains heat. Wait until it cools down before charging.
• Do not allow any metal part to short circuit the receiver batteries or other electrical/electronic device on the model.
• Immediately stop running if your RC model gets wet as may cause short circuit.
• Please dispose of batteries responsibly. Never put batteries into fire.
R/C & BUILDING TIPS
• Make sure all fasteners are properly tightened. Check them periodically.
• Make sure that chassis screws do not protrude from the chassis.
• For the best performance, it is very important that great care is taken to ensure the free movement of all parts.
• Clean all ball-bearings so they move very easily and freely.
• Tap or pre-thread the plastic parts when threading screws.
• Self-tapping screws cut threads into the parts when being tightened. Do not use excessive force when tightening the self-tapping screws because you may strip out the thread in the plastic. We recommended you stop tightening a screw when you feel some resistance.
• Ask your local hobby shop for any advice.
Please support your local hobby shop. We at XRAY Model Racing Cars support all local hobby dealers. Therefore we ask you, if at all possible, to purchase
XRAY products at your hobby dealer and give them your support like we do. If you have difficulty finding XRAY products, please check out www.teamxray.com to get advice, or contact us via email at [email protected], or contact the XRAY distributor in your country.

IMPORTANT: When you build the differential, do not tighten it fully initially; the differential needs to be broken in properly. When you build the diff tighten it very gently.
When you put the diff in the car and complete the assembly, run the car for a few minutes, tighten the diff a little bit, and then recheck the diff. Repeat this process several times until you have the diff tightened to the point you want it. Final adjustments should ALWAYS be made with the diff in the car and on the track.

TIP
For easy and comfortable installation of the #305241 plastic caps use pliers as shown.
OPTIONAL ECS DRIVE ShAFTS
ECS shafts are available optionally in both
50mm and 52mm lengths. The ECS drive shafts were developed to decrease front wheel vibration when racing with a solid front axle, thus providing a much smoother and quieter ride and increased steering.
IMPORTANT!
DO NOT use the plastic caps with composite solid axle included in the kits.
The new #305241 3.5mm plastic caps are for use ONLY with ALU ball diffs or the XRAY Multi-Diff™.
DRIVE SHAFTS
#305323 50MM - STEEl
#305324 52MM - STEEl
#305325 50MM - ECS
#305326 52MM - AlU
#305327 52MM - ECS
#305328 50MM - AlU
Longer drive shafts (52mm) make the car easier to drive because they give more traction and better stability, mainly in chicanes. However, the car will understeer more than with shorter (50mm) shafts which give a lot of steering and impart aggression to the car. You may also combine different lengths of shafts in front and rear (for example, using long shafts in the rear and short shafts in the front) depending on track conditions.
Both left & right shafts should ALWAYS be the same length at one end of the car (front or rear).
52mm shafts are recommended for carpet and big asphalt tracks
50mm shafts are recommended for small-medium tight asphalt tracks

INITIAL POSITION
Initial position = MIDDLE ball
Use the INNER ball on low-traction tracks (mainly low-traction carpet tracks).
The car will have more traction & more steering, but will be more difficult to drive because the car will roll more. Recommended on chicane tracks.
Use the MIDDLE ball on low- to medium-traction tracks (asphalt, carpet). The car will have a little less rear traction and the car will roll little less which will make it easier to drive with more cornering speed.
Use the OUTER ball on high-traction tracks (mainly high-traction asphalt tracks).
The car will roll even less which will allow the use of more throttle in the corners, however the car will have less traction.

➊
Fully extend the piston rod so the piston is at the bottom of the shock body.
➋
Hold the shock upright and slightly overfill the shock body with shock oil.
➌
Let the oil settle and allow air bubbles to rise to the top. Slowly move the piston up and down until no more air bubbles appear. Add shock oil as necessary.
➍
Pull the piston rod most of the way out of the shock body. Let the shock rest for 5 minutes to allow the air bubbles to escape.

INSERT
After you insert the membrane ensure that it sits properly all around the alu cup.
When installing the shock cap assembly on the shock body, some oil will leak out... this is normal.
Tighten the cap gently and clean off any excess oil. If the cap it tightened too much, rebound is difficult to adjust.
If the cap is not tightened enough, the cap may unscrew slightly and the shock may leak.
After the shock is assembled, the shock rod will push itself out of the shock body fairly quickly.
Follow the next procedure to adjust the rebound.

After the shock is assembled you have to set the Shock Rebound.
1. Release the shock composite lower cap.
2. VERY SLOWLY do the following: Fully pull out the shock rod, push it back in fully, and then fully pull it out once more. Repeat this procedure the following number of times to achieve the desired Shock
Rebound setting:
10 times - approximately 75% rebound (high rebound - suggested for very low traction track)
15 times - approximately 50% rebound (medium rebound - suggested for standard track)
20 times - approximately 25% rebound (low rebound - suggested for very high traction track)
During the Rebound Adjustment procedure shock oil will leak out of the shock body through the O-ring on the shock rod... this is normal. During the Rebound Adjustment procedure DO NOT open the upper shock cap.
3. After you have set the Rebound Adjustment, re-install the shock lower composite cap.
4. Check the Shock Rebound setting by pushing the shock rod fully into the shock body, releasing it, and observing how far the shock rod extends by itself:
* 25% out of the shock body (low rebound)
* 50% out of the shock body (medium rebound)
* 75% out of the shock body (high rebound).
If the shock rod rebounds too much, return to Step 1 and repeat the procedure.
If the shock rod does not rebound enough, you will have to refill the shock with shock oil, and then repeat the bleeding and Shock Rebound procedures.

Shock length adjustment:
It is VERY important that all shocks are equal length.
Fully extend the shock absorber and measure the end-to-end length; we recommend using digital calipers to give an accurate measurement. If a shock absorber is shorter or longer than others, adjust the shock length by tightening or loosening the ball joint on the shock rod.
Damping adjustment:
If you built the adjustable shocks, fully extend the shock rod and turn it slightly to lock the piston in the shock body.
Turning the shock rod fully CCW aligns 4 holes in the pistons (softest damping). Turning the shock rod fully CW aligns 1 hole in the pistons (hardest damping). The shocks have four settings, each of which can be felt by a slight "click".
REAR SHOCKS
(C=2.6 springs)
Set all four shocks initially to position 3 (3 holes open): turn fully
CCW, then turn CW by 1 click.

Install pivot balls into top pivot or lower ball joint as shown, on the proper sides.
Note that the lower pivot ball has an extra shoulder.

Attach servo arm to servo output shaft using screw from servo. Servo saver must be perpendicular to chassis when servo is in neutral.
IMPORTANT!
When adjusting steering on the radio, we recommend using full steering adjustment in order to get the best steering from the car. It is important to verify that the steering block does not touch the C-hub; that would lead to chassis tweak due to extra servo strain.

When installing the motor on the bulkhead, rotate the spur gear so the motor screw can be installed through a hole in the spur gear. See the detail image below.
Adjust the motor so the pinion meshes with the spur gear properly. Make sure the gear mesh is not too tight.
There should be a small amount of play between the teeth of the pinion gear and the spur gear.
Recommended:
3x2.5mm set screw
(#901302)
DETAIL
For tightening and loosening the pinion set screw, use the indicated chassis hole.
MOTOR
(NOT INCLUDED)
Some motors do not have a chamfer on the motor housing. If your motor does not have a chamfer on the housing and you want to use a small pinion, the motor may touch the top deck.
Use a moto-tool with grinding bit or file to remove material; this will allow the motor to move more closely to the spur gear.

TECH TIPS
Tech tip for page 15. step 3.
When driving in high-grip conditions (carpet races), we recommend using the stands to connect the servo horn holders to the top deck. The car flex will be stiffer, making the car easier to drive. For more information, see Multi-Flex
Technology™ settings below.
The stands and 3x14 screws are in the last aid bag.
You must first remove the 3x5 screws from the servo horns first.
Tech tip for page 27. step 2.
If there is not enough space for electronics due to a large receiver or ESC, you can cut one servo holder to create more space. If you do this, use double-sided tape to prevent servo movement.

Multi-Flex Technology™
The T3 has 4 kinds of Multi-Flex Technology™ settings: soft, soft-medium, medium-stiff, and stiff.
The amount of stiffness used depends on the track surface.
SOFT - Soft setting is recommended to use on low-traction asphalt or carpet tracks. Car with this setting gives maximum traction.
However, when the traction starts to increase, we recommend changing the MFT™ setting accordingly. When you use a soft setting, even though car feels good from the beginning, after some racing time the tires overheat and then the will become difficult to drive.
SOFT-MEDIUM - By adding two screws on layshaft bulkhead, car has more steering into the corner. However, car will become a little more loose and therefore this setting is recommended when traction starts to increase.
If traction continues to increase (e.g., on carpet), change from soft-medium setting to medium-stiff setting.
MEDIUM-STIFF - When traction increases rapidly, we recommend using stands to connect servo horn stands to the top deck. This will make the car easier to drive and be more direct. However, for low-traction conditions we recommend taking them out because the car will understeer. These stands are used mainly on high-traction carpet tracks.
When the traction is very high (mainly on big races where many competitors drive), we recommend to use stiff setting to reduce the chances of tire overheating and traction rolling.
STIFF - With the stiff setting the car is easy to drive while providing enough steering to make car fast into and out of corners. The stiff setting is not recommended for low-traction conditions because the car will have not enough steering or traction.
For super-high traction when even the stiff flex setting is not enough and car is difficult to drive, we recommend checking the Set-up Book for set-up changes. For higher-traction conditions, thicker shock oil and harder springs & anti-roll bars are recommended.
For very-low traction when even the soft setting does not give enough grip and the car is too loose, we recommend checking the Set-up Book for set-up changes. For lower-traction conditions, softer shock oil, springs & anti-roll bars and more rear toe-in are recommended.
SETTING SUMMARY:
Soft setting: Technical or low-traction asphalt track
Medium-stiff setting: medium-high traction on carpet or asphalt track
Soft-medium setting: medium traction on asphalt track.
Stiff setting: Very-high traction, mainly carpet track.
