Savage X 4.6 RTR

To prevent any serious personal injury and/or damage to property, please be responsible when operating all remote controlled models. Extra attention is

called for when operating any glow fuel powered model. These models can exceed speeds of 30 m.p.h. and use highly poisonous and flammable fuels.

Before Running

Please read manual (with parent, guardian or a responsible adult if necessary).

While Operating

Please do not run on a public street, this could cause serious accidents, personal injuries and/or property damage.

Please do not run near pedestrians or small children.

Please do not run in small or confined areas.

Before Operating

Make sure that all screws and nuts are properly tightened.

Always use fresh batteries for your transmitter and receiver to avoid losing control of the model.

Make sure no one else is using the same radio frequency as you are using.

Please confirm the neutral throttle position.

After Running

Shut off engine first, then turn off receiver switch and turn off transmitter last.

After running Savage X 4.6 RTR, it is necessary to perform routine maintenance. Failure to do this can result in increased wear and damage to the engine and chassis.

Heat, Fire, and Fuel Safety

Never use gasoline in a glow engine. Use glow fuel specifically designed for model car engines.

Do not run near open flames or smoke while running your model or while handling fuel.

Always store fuel in a well ventilated place, away from heating devices, open flames, direct sunlight, or batteries. Keep glow fuel away from children.

Glow fuel is flammable and poisonous. Glow fuel powered model engines emit poisonous vapors and gasses. These vapors irritate eyes and can be highly dangerous to your health.

How To Control R/C Models

Retract the antenna

Make sure no one else is using the same radio frequency as you are using. Check the radio

system and range before every driving session. To properly check the range, have a friend hold

the R/C car with the engine off and walk to the farthest distance that you plan to operate your

R/C car. Operate the controls to make sure the model responds correctly. Do not operate the

model if there is any problem with the radio system. If you switch on the R/C car first before the

transmitter, you may lose control of the R/C car.

If you switch off the transmitter first before the R/C car, you may lose control of the R/C car.

Turning the transmitter wheel left and right will make the

front tires of the car do the same. Turning the wheel a

small amount will make the model perform a wide turn.

Turning the wheel a large amount will make the model

perform a sharp turn.

Pull the throttle to drive forward and press it away for

brakes. The more you pull the throttle, the faster the car

will move forward.

before starting engine. If you switch on the R/C car first before the transmitter,

you may lose control of the R/C car.

To prime the engine, use your finger to cover the exhaust tip. crank engine with Roto

Start until fuel reaches the carburetor and no bubbles are seen. Using Roto Start too

long will cause the engine to be flooded.

you can pinch the fuel line to stop

the flow of fuel to the carb.

HPI engines will feel tight at the top of their stroke when they are new or when they have not reached

their normal operating temperatures. The piston and cylinder sleeves are designed to achieve proper

running tolerances when they are properly broken in and are operating at the correct temperature. New

engines need a break in period of about 3 to 4 tanks of fuel before they can be run at full throttle, if not the

engine could be damaged.

Break in should be performed on a flat level surface.

Glow Plug and Starter

Attach the glow igniter to the glow plug. Start the engine by

cranking with the Roto Start. Remove the glow igniter as soon

as the engine is running.

If the glow plug igniter is left connected while the engine is

running, it will drain the battery and damage the glow plug.

The engine must never be run without the air

filter in place.

Attention

New engines need a break in period of about 3 to 4 tanks of fuel before

they can be run at full throttle, if not the engine could be damaged.

Less Fuel = Lean

Lean Fuel Mixture

Provides strong and efficient combustion and

The idle speed is set after the high-speed needle is adjusted and the

engine is up to operating temperature. To properly set the Idle

Adjustment Screw, turn on your radio system and set the throttle trim on

the transmitter so that the throttle is in its neutral position. This will

ensure that the throttle slide is fully closed and resting against the idle

adjustment screw. Turn the idle adjustment screw counter clockwise to

reduce the idle speed, or clockwise to increase it. The idle speed should

be set high enough to keep the engine running smoothly but not engage

the clutch and turn the wheels. Too high of an idle speed will

prematurely wear out the clutch shoes and brake disk.

Idle should be set so that at neutral throttle position the engine is running without engaging the clutch and moving the car forward.

Improper Idle Speed Setting:

Clutch engaged and wheels turning.

Proper Idle Speed Setting:

Engine runs smoothly without wheels turning.

If idle is unstable, adjust the low speed

needle to get a stable idle. Afterwards,

you need to readjust the idle adjustment

screw.

We recommend that you do not touch the Low Speed Needle.

If adjustment is needed, the low-speed mixture is set after the high-speed needle

is adjusted and the engine is up to operating temperature. Set the needle flush (Factory Setting) with the carburetor body, this setting is

ideal for breaking in and starting your motor. For increased performance turn the needle in 1/8 turn increments; this will improve bottom

end throttle response. To test your setting, place the car on the ground and let the engine idle for 30 seconds then accelerate to 3/4

throttle. If there is a lot of white smoke and the car accelerates slowly, the mixture is too rich. If the engine accelerates quickly and then

sputters, the mixture is too lean. When the low-speed needle is set correctly the engine's throttle response should be smooth and quick.

CAUTION: Never turn in more than 2 turns from flush this will cause the engine to run too lean and may damage your engine!

If the Low

Speed Needle is set too lean you will experience the following:

Flame out at part or 3/4 throttle, overheating (temperatures above 280 F at

the glow plug). If your engine is running too lean, reset the Low Speed Needle to its factory setting (Flush) and start the tuning process

again.

Following the tuning steps, tune the engine until its maximum performance is reached. While a lean motor will have higher performance, it can

lead to premature engine wear or failure. Use the following information to tune your engine to your driving conditions. Remember a slightly rich

setting is a safer setting.

Engine temperature can tell you if the engine is running lean or rich. If you check the engine temperature, you can understand how to tune your

carburetor. Adjust carburetor to keep the operating temperature below 250°F. If the engine temperature goes over 250°F, the engine will be

damaged.

If you turn the needle past the closed point, it will be damaged. Do not tighten past closed.

If you lose the needle setting, you can reset the factory setting (See Section 2-10) and re-tune.

How Glow Plugs Work

Proper Glow Plug Selection

Flush

High Speed Needle, Idle Adjustment Screw and Low Speed Needle are

designed to be set flush with the carburetor body. This makes it easy to

reset the carburetor to the Factory Break In Setting if needed.

Unlike full sized car engines that use spark plugs and a distributor to fire the cylinders in the combustion cycle, glow engines rely

on glow plugs. In a Nitro engine, ignition is initiated by the application of a glow igniter. When the igniter is disconnected, the heat

inside the combustion chamber keeps the glow plug filament glowing, firing the next cycle, thereby keeping the engine running.

Ignition timing in a glow engine is automatic. At higher RPM’s the plug becomes hotter, firing the fuel/air mixture earlier. At lower

RPM’s the plug becomes cooler, firing the fuel/air mixture later. Since the glow plug performs so many important functions,

proper plug selection and maintenance are crucial to a properly running engine.

Proper glow plug selection depends on several factors: Fuel

type, nitro methane content, weather, and altitude can drastically

affect performance. Finding the best combination of fuel and

plug temperature for your driving condition is the key to getting

the maximum performance out of your Nitro Star Engine.

Extending the Life of your Glow Plug

To maximize and extend the life of your glow plug follow these simple tips;

Remove the glow igniter when using more than 1/2 throttle or if the engine does not start after a few seconds.

Do not run the engine lean, lean conditions will overheat the plug causing the element to be damaged or fail.

Use the best Fuel/Plug combination for your driving conditions.

Use a fuel that has a lower nitro content.

When to Replace the Glow Plug

Fuel and temperature will have an effect on the performance,

reliability, and life span of the glow plug and therefore it

should be considered an expendable engine component.

Aside from burnout or plug failure, there are several signs that

can indicate the plug should be replaced.

Plug filament/plug body is discolored or the surface is rough.

Plug filament is distorted or bent.

Engine cuts out when idling.

Engine becomes difficult to start.

Air Filter Maintenance

Dirt is the biggest enemy of a nitro engine and proper air filter maintenance is one of most important factors that

will affect your engines longevity. We recommend cleaning the element after every run. It is always a good habit

to check the element after every run to make sure it is properly seated in the filter body and that the body is fully

seated on the carburetor. Never run the engine without the air filter.

Remove and clean the air filter with nitro fuel when dirty. Spray fuel

through the clean side to ensure proper dirt removal. Squeeze the filter

to remove excess fuel. To re-coat the air filter with oil, place the

element in a plastic bag with several drops of air filter oil. Using your

fingers, work the oil into the element making sure it is evenly distrib-

uted.

After properly cleaning the filter element make sure it is reinstalled correctly. Make sure there are no gaps

between the element and body. Make sure the filter is fully seated on the carburetor and secure it with a tie strap.

Never run the engine without the air filter.
