•  Never modify the engine or muffler.

•  Confirm the position of needle and idling before running. Be sure to run a new engine smoothly.

•  Make sure the air filter is clean and oiled.

•  Never run your engine without an air filter. Your engine can be seriously damaged if dirt and debris 

get inside the engine.

•  For proper engine break-in, please refer to the manual that came with the engine.

•  The engine may not start or run properly if the air filter is dirty, or choked with sand and dust.

•  If the fuel pipe is choked or deteriorates, the engine may not start, and there is danger that fuel will 

leak out.

1.  Make sure the transmitter and receiver batteries are fully charged.

2.  Make  sure  that  your  transmitter  and  receiver  are  both  on  the  same  frequency.    If  you  have  a 

transmitter with multiple model memory, make sure you have selected the proper profile for your car.

3.  Put the car on the starter box and keep the tires from touching the ground.

4.  Turn on the transmitter.

5.  Turn on the receiver in the car.

6.  Make sure the steering servo and engine servos work normally and adjust them correctly.

7.  Put fuel in the fuel tank, and close the cap securely.

8.  Apply the glow igniter to the engine glowplug.

9.  Push the model car onto the starter box to start the engine. (If the engine is new, follow the instruction 

manual and be sure to break in the new engine properly).

10. When the engine has started, remove the glow igniter.

11. Follow your engine break-in procedure and tune the engine as appropriate.

STARTING AND RUNNING THE ENGINE

Be sure to observe the following starting process. Failure to do so may cause the model car to start suddenly, which may lead to damage or unexpected accidents.

STOPPING THE ENGINE

Before you stop the engine, try to make sure the engine is at idle first. There are several ways to stop the engine:
•  Use a rag to cover the exhaust tip. Be careful! The exhaust is extremely hot so use a thick rag and gloves.

•  Pinch the fuel tubing to stop the flow of fuel to the carb. Be careful, this can make the motor run lean 

which can damage the motor.

•  Put your hand over the air filter, or squeeze the air filter element to block the airflow.

•  Press an object (such as a screwdriver handle or shoe) against the rotating flywheel to stop its 

rotation. Be very careful, and do not stick your hand or fingers near the rotating flywheel.

FINISHING OPERATIONS
1.  Stop the engine.

2.  Turn off the receiver in the car

3.  Turn off the transmitter.
MAINTENANCE AFTER RUNNING

Take proper care of your car after running to keep it performing well, and take notice of any damage and wear.
1.  Do not leave fuel in the tank.

2.  Go outside to drain any residual fuel from the exhaust pipe.

3.  Clean the car and remove all sand, mud, and other debris.

4.  Use after-run oil in your engine after you have finished running for the day.

•  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. 

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.

ENGINE OPERATION

PREPARING TO OPERATE THE ENGINE

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.

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 ball-

bearings 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.

MAINTENANCE

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.

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.

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 3x14 (#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 STEEL™

The HUDY Spring Steel™ used in the car is the strongest and most durable steel material on the RC market. While items made from HUDY Spring Steel™ are still subject to wear, the lifespan is considerably 

longer than any other material. As parts made from HUDY Spring Steel™ 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.
