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

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,

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.

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.

GTX TECH TIPS

TIP FRONT & REAR DIFF GEAR MESH ADJUSTMENT

If there is too much or too little diff side play, this may create non-optimal gear mesh between the diff gear and the pinion drive gear. This is easily resolved by inserting 1 or 2 of the included thin shims behind a diff outdrive ball-bearing, depending on how much play there is.

THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE GAP:

TO CLOSE A WIDE GAP

CLOSE A WIDE GAP

To CLOSE a wide gap: add 1 or 2 shims against diff spur gear

TO OPEN A NARROW GAP

OPEN A NARROW GAP

To OPEN a narrow gap: add 1 or 2 shims on the other side of the diff, away from spur gear

CHECK GEAR MESH AND DIFF PLAY ONLY AFTER THE ENTIRE GEARBOX IS MOUNTED TOGETHER WITH THE SUSPENSION HOLDERS ON THE CHASSIS. ALL PARTS ARE DESIGNED TO HAVE CERTAIN PLAY AND IT IS ALL DESIGNED BY PURPOSE.

SUSPENSION & DRIVETRAIN MAINTENANCE
· Check suspension for free movement during building and operation, and especially after running and if you have crashed the car. If the suspension does not move freely, use the appropriate HUDY Arm Reamer to clean and resize the holes of the suspension arms.
· Regularly check the drive shaft pins (both side and center) and if they show any wear must be immediately replaced by new pins. If the car is run with worn pins, excessive wear on the diff outdrives will result. The 106000 HUDY Drive Pin Replacement Tool (for 3mm Pins) is a compact, rugged multi-use tool set for replacing 3mm drive pins in drive shafts. Use the HUDY replacement drive shaft pins 3×14 (#106050).

· Regularly inspect and replace the connecting pins which connect the center drive shafts with the pinion gear, and also the pins that connect the wheel drive shafts with wheel axles. Use HUDY Graphite Grease to lubricate the drive shaft connecting joints and the diff gears.
· Pivot balls and ball-joints will naturally wear for some time and will generate play. If there is too much play the pivot balls and ball joints need to be replaced.
· If the car is run in wet conditions, apply WD-40® on all drivetrain parts before the run. After the run, clean and dry the parts again.

HUDY SPRING STEELTM
The HUDY Spring SteelTM used in the car is the strongest and most durable steel material on the RC market. While items made from HUDY Spring SteelTM are still subject to wear, the lifespan is considerably longer than any other material. As parts made from HUDY Spring SteelTM wear, the brown color will after some time “go down” but it will not affect the strength of the material. The brown color is only a surface treatment and if the brown color will wear the durability of the part will be still strong.

TIP DRIVE SHAFT PIN SERVICING
To enjoy the longest possible lifespan of the drive shafts and diff outdrives, it is extremely important to properly service the drive shaft pins. Inspect the pins after every 3 hours of runtime. If the pins show any wear, replace them with new pins.

Do not use drive shafts when the pins are worn.

Press out the worn pins.

Press in new pins and regularly inspect for wear.

For easy drive pin replacements use #106000 HUDY Drive Pin Replacement Tool.

To replace the worn pins use only premium HUDY drive pins #106050.

Extend the shock shaft completely. Fill the shock body with the shock oil. For the shocks use 800cSt 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.

Install the shock membrane into the groove in the upper shock cap.

Gently place the shock cap assembly onto the filled shock body. Excess oil will spill from the shock. Screw the shock cap onto the body by only a few turns.

Gently push the shock shaft completely into the shock body. Excess oil will flow through the hole in the shock cap.

Keep the shock shaft pushed in the shock body and tighten the shock cap completely. The rebound will be at approximately 0%.

Before cutting and making holes on the body, put the unpainted body on the chassis to confirm the mounting position and location for holes and cutouts.
Before painting, wash the inside of the body with mild detergent, and then rinse and dry thoroughly. Mask all windows. Apply paint masks as appropriate. Paint the body using paints formulated for polycarbonate bodies. When the paint is dry, remove the masking. Carefully cut out the body using appropriate scissors or cutting tools. When you have finished cutting, peel off the external protective films.

Use Body Reamer (HUDY #107602) for all holes.

MAINTENANCE

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 rubber bladders and 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.
· 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.

· If installing new rubber bladders, carefully trim the thin excess rubber from the edges of their lips. Curved body scissors work the best.
· Regularly inspect the amount of dirt on the felt protector in the shocks (if present) and regularly replace with a new one.
· 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.

BEARING MAINTENANCE Ball-bearings in an off-road car or truggy must be properly maintained for smooth operation and long lifespan.
Typically, the ball-bearings included in new cars are greased for highest lifespan and as such the drivetrain may not seem to be as free as with lightly-oiled ball-bearings. However, when the car is run the ballbearings will become more free and the drivetrain will become very efficient.
There are several types of bearings discussed here: bearings which already come greased from the factory, bearings which must be lubricated using the HUDY Bearing Grease, and then there are also bearings in the steering system which need to be lubricated with HUDY Bearing Oil.
The following procedures are recommended to clean all of the bearings in your off-road car or truggy. For high-competition racing, we recommended doing this every 3-4 weeks, or before a major race.

1. 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.
2. Spray the seals with motor cleaner and blow dry with compressed air. 3. Spray the bearing on both sides with motor cleaner. 4. Spin the bearing while it is still wet to dislodge any particles with the cleaner. 5. Spray the bearing on both sides again. 6. Blow both sides of the bearing dry with compressed air to make sure particles come out.

7. 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.
8. Place one drop of bearing oil into each side of the bearing. 9. Replace both seals at the same time by lining them up on each side of the bearing and lightly press-
ing 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.

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.

CLUTCH BEARINGS To prolong the lifespan of the clutch bearings, they must be regularly cleaned and lubricated (preferably after each run) using a high- quality grease such as HUDY Bearing Grease. However, after some time the clutch bearings must be replaced with new ones. RECOMMENDED PRODUCTS
· Use HUDY Bearing Grease to regularly lubricate grease-bearing ball-bearings. · Use HUDY Bearing Oil to lubricate the bearings of the steering system. · Use HUDY Bearing Grease to regularly lubricate the clutch bearings.

SUSPENSION & DRIVETRAIN MAINTENANCE

· Check suspension for free movement during building and operation, and especially after running and if you have crashed the car. If the suspension does not move freely, use the appropriate HUDY Arm Reamer to clean and resize the holes of the suspension arms.
· Regularly check the drive shaft pins (both side and center) and if they show any wear must be immediately replaced by new pins. If the car is run with worn pins, excessive wear on the diff outdrives will result. The 106000 HUDY Drive Pin Replacement Tool (for 3mm Pins) is a compact, rugged multi-use tool set for replacing 3mm drive pins in drive shafts. Use the HUDY replacement drive shaft pins 3×14 (#106050).

· Regularly inspect and replace the connecting pins which connect the center drive shafts with the pinion gear, and also the pins that connect the wheel drive shafts with wheel axles. Use HUDY Graphite Grease to lubricate the drive shaft connecting joints and the diff gears.
· Pivot balls and ball-joints will naturally wear for some time and will generate play. If there is too much play the pivot balls and ball joints need to be replaced.
· If the car is run in wet conditions, apply WD-40® on all drivetrain parts before the run. After the run, clean and dry the parts again.

HUDY SPRING STEELTM
The HUDY Spring SteelTM used in the car is the strongest and most durable steel material on the RC market. While items made from HUDY Spring SteelTM are still subject to wear, the lifespan is considerably longer than any other material. As parts made from HUDY Spring SteelTM wear, the brown color will after some time “go down” but it will not affect the strength of the material. The brown color is only a surface treatment and if the brown color will wear the durability of the part will be still strong.
