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 RC 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 short-circuits, 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,

R/C & BUILDING TIPS

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 shortcircuit 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.

• 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.

USE PROPER AMOUNT OF OIL IN THE DIFFS

Use a digital scale to measure the exact amount of oil in the diff. Remember that during operation the diff gets hotter and the heat may allow the oil to expand. If there is too much oil inside it may interfere with the diff operation and damage the internal gears.

TO ENSURE YOU HAVE THE SAME AMOUNT OF OIL FROM REBUILD TO REBUILD, DO THE FOLLOWING:

Rear diff

OIL

Silicone oil 5.000cSt Fill just above the diff pin.

5.000cSt

CARPET

Fill differential up to the

top of the diff pin.

DO NOT fill the diff to the

top of the housing.

Outer position = 1° or 0.75mm from center.

The XRAY rear alu lower suspension holders provide great range of adjustment for the rear suspension. Using different combinations of eccentric bushings, fine adjustment of rear anti-squat, rear toe-in, rear roll center, and rear track-width can be obtained. For more information about the influence of rear anti-squat, rear toe-in, rear roll center and rear track width on car handling, please refer to HUDY Set-up Book (#209100).

Extend the shock shaft completely. Fill the shock body with the shock oil. For the FRONT shocks (short) use 550cSt or 500cSt oil. For the REAR shocks (long) use 450cSt or 500cSt oil.

Move the shock shaft up and down a few times to release the air bubbles trapped beneath the piston.

Orient the filled shock vertically for several minutes with the shock shaft fully extended. The remaining air bubbles will release.

Follow the steps below to set the shock rebound to the default setting of 0%.

For more in-corner steering and better steering response, aluminum servo horns may be used.

For increased safety of the servo during a crash we suggest to use optional servo saver that will absorb impacts and will eliminate servo damage. To install the servo saver the optional alu stands.

SHOCK MAINTENANCE

The most important maintenance task for keeping consistent shock performance is refilling and bleeding them correctly. If built correctly, it will not be necessary to re-build them often. Replacing warped/hard o-rings, scarred piston rods, or shaved/split/loose composite upper and lower ball joints are also important.

• For club racing, it is recommended to check the shocks for air inside before each race and only re-fill and bleed them if necessary. Before each race day, make sure you take the spring off of each shock, hold it up to your ear, and quickly compress the shock rod fully into the body while listening for any air making a “whistling” or “squishy” sound as it passes through the piston holes. If you hear any air, refill and bleed your shocks. For high-competition racing, it is recommended that the shocks be re-filled and bled before a large event.

BEARING MAINTENANCE

Ball-bearings in an off-road car must be properly maintained for smooth operation and long lifespan.

The XB2 ball-bearings are degreased and are lubricated with HUDY Bearing Oil. The following procedures are recommended to clean all of the bearings in your off-road car. For high-competition racing, we

If you spin test the bearing after you have re-oiled and sealed it, it will not spin freely for an extended period of time. The lightest of oils may allow it to spin for 1-2 seconds. This is normal and once you have mounted the bearings in the car again, the drive train will spin freely.

Make sure you use a motor cleaner that does not leave a residue after it dries as this may cause drag and wear in the bearings.

recommended doing this every 3-4 weeks, or before a major race.

➊ Remove the seals on both sides of the bearing (if present). If the seals bend a little and you can see

a kink, carefully flatten the kink out by hand.

➋ Spray the seals with motor cleaner and blow dry with compressed air.

➌ Spray the bearing on both sides with motor cleaner.

➍ Spin the bearing while it is still wet to dislodge any particles with the cleaner.

➎ Spray the bearing on both sides again.

• If building or pairing new shocks, always make sure they are the same length using a shock length measuring tool and adjust the lower ball joints as needed.

• During regular shock operation, oil naturally gets on the shock shaft and drop-by-drop slightly gets out of the shock body. Shocks should be inspected regularly after each race, and oil replaced as required.

➏ Blow both sides of the bearing dry with compressed air to make sure particles come out.

➐ Hold the inner part of the bearing with my left thumb/forefinger and spin it to make sure it

spins free without any abnormal vibrations or sounds.

➑ Place one drop of bearing oil into each side of the bearing.

➒ Replace both seals at the same time by lining them up on each side of the bearing and

lightly pressing them in all the way around the bearings circumference with your thumb and forefinger. Do not press too hard or use any type of tool, such as a wrench tip, to push the blue seals in as they will push in too far, bend and cause drag.
