Redcat Racing Reviews and Tips – Why Does Your Redcat Nitro Engine Rev Right After Starting?

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This is a RedCat Racing tutorial for beginner remote control race car hobbyists that teaches simple troubleshooting techniques to maximize your car engine’s performance. It tackles one of the most common problems that racers face, why an engine revs up right after it has started.

To Start, remove the top or external portion of your race car and check the internal parts to see what’s wrong. There are many reasons why your engine revs up after starting. One of the main reasons is the need to calibrate your engine’s carburetor. Check for the carburetor by removing the air filter. It is a layer of white foam in the middle of the engine assembly which directly covers the entrance to the carburetor.

The carburetor opening is adjusted with the help of the idle switch. Ideally, there should only be a millimeter opening on the carburetor, a larger opening will usually make the engine rev up after you have started the engine. Always place the opening to only one millimeter to maintain the function of your engine.

You may also adjust the opening with the use of the throttle servo arm. With just a few turns of the throttle push rod of the throttle assembly you will also be able to get just a millimeter hole on the carburetor.

As you make manual adjustments with the carburetor idle switch, power the car on as well as the radio controller so you can readily adjust the throttle trim as well. Making sure that your Low Speed Needle is not too lean will also reduce engine rev every time you start it.

BY making sure than the carburetor is open with just a millimeter and your Low Speed Needle is not too lean will avoid engine rev up upon starting it. It will also assure that your engine will perform better and will last longer too.

 

 

Redcat Racing Reviews and Tips – Cleaning and Fixing Your Redcat Nitro Engine Carburetor

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This is a RedCat Racing tutorial that will show you the basics of cleaning your race car engine’s carburetor. A clean carburetor will supply the engine with clean and efficient power and will also improve the lifespan of your remote control car engine. This is one of the many RedCat Racing tutorials that teach the basics of maintenance and expert handling of your race car’s delicate parts.

You can easily tell when your carburetor needs cleaning and maintenance when you cannot freely turn the carburetor speed needles or you turn them and there is not performance change in your vehicle. Take the carburetor and clean it out, then remove the needle valve from the carb. Don’t put too much force as you use nose pliers on the carburetor needle valve.

Wear protective glasses and gloves when cleaning the carburetor. After placing a small amount of nitro fuel on the part, gently blow the carburetor holes to remove the dirt and the air away. Clean everything and make sure there is no stuck dirt. Be gentle with the carburetor assembly and avoid scratching any part or damaging any small part.

Place the High Speed Needle and the Low Speed Needle back with a screwdriver. Never over tighten any screw on the carburetor since it can damage the assembly. Set the idle screw; you may see for yourself the position of the opening of the carburetor when this important part is adjusted. Generally you want to leave at least 1 MM open.

Check if all the moving parts are OK before you replace it back to the car engine. Place the carburetor back where it is located on the car. Attach the throttle to the carburetor assembly and screw the part back in. Power the car; use the manual pull string and the glow plug igniter to start the engine. With your remote, adjust the throttle and the steering trims.

It’s time to test out your Recat Nitro Vehicle!

Redcat Racing Tutorials and Reviews – How to Install a Redcat Electric Starter

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This is a RedCat Racing training tutorial. This is just one of the tutorials that teach any hobbyist the basics of set up and maintenance of your remote control parts. This Redcat tutorial will show you how to replace the pull starter with a new electric pow

Replacing a manual pull starter is easy when you have a RedCat Racing electric power starter. Remove the electric power starter and see if you have all the materials ready. Remove the outer cover of the nitro vehicle. You may either take the entire engine out or take the whole rear suspension out to replace the manual pull start. (The Engine is easier)

replacing nitro engine pull start

Remove the engine out by releasing the four screws at the back. Replace the manual pull start by removing the screws that attach it to the engine. The reason why most hobbyists replace a manual pull start is that the string on the pull start often breaks.

Once that the engine can be started with the use of the electric power starter, you are ready to place the engine back on the car and screw it back in. Keep the old manual starter for future use just in case you need it some day. Check if the electric power starter is able to start the motor; insert the starter stick or connector from the back of the car which is directly accessible from the back of the car.

Start your car. Lay it flat on the ground but don’t place the outer cover just yet. Start the engine using the electric starter and starting the glow plug. The engine should start with just a few strokes from the electric power starter.

Redcat Racing Tutorial – How to Set Up The Gear Mesh

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This Redcat Racing tutorial will teach you how to set up the gear mesh of your race car. Any hobbyist knows that the gears of a race car is what makes every wheel turn and without proper set up and maintenance, your car will never perform the way you want it to be. Here is a step by step procedure on how to set up the gear mesh:

A tight or loose gear mesh will affect the performance of your car. To be able to know if you have set it properly, you can do some simple diagnostic procedures.

redcar racing spur gear teeth and clutch bell

1. Feel the way the gears turn. Even when your race car has no power, turn the front wheels and feel the free-flowing motion of the gears and at the same time listen for any disturbing gear noises. Any jamming movements or any disruption on the free movement of the gears would mean that it is too tight. All four wheels should move altogether when you move a single wheel.

Spin Wheels on Redcat Gear Mesh Test

Take a simple paper about half inch wide; slide it in between the gears. This will allow you to check for the setting of the gear mesh. You should be able to clearly see the teeth of the gear on the slip of paper. If you cannot see these, it would mean that the gear mesh is too loose or if the paper comes out torn or too crumpled, then the gear mesh is too tight.

gear mesh teeth waves

Setting the gear mesh is done by loosening the screws of the engine; push the engine to the spur gear. Take the entire engine out and not just the bell gear. Place a piece of paper in between the gears again to check for the tightness or the looseness of the gears.

Gear Mesh Screws

If the gears appear to look tight, loosen the screws at the back and do the paper test once more. Place your car on a block to test the wheels freely. All the wheels should turn freely and without causing any disrupting noise.

Redcat Racing Tutorial – How to Install and Replace the Glow Plug in a Redcat Nitro Vehicle

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This RedCat Racing tutorial will tell you how to install and replace a glow plug. Learning all about maintaining your race car’s glow plug will allow you to take care of your car more and keep it running as efficient as it can be.

Finding the glow plug takes precision. Take the outer shell of your race car and find the glow plug. It is mostly located inside the piston of the engine manifold. You need only one tool to remove and replace an ailing glow plug and that is your 4-way wrench that is included in the nitro starter kit.

Locate the piston and with your 4-way wrench take the glow plug out with a counterclockwise motion.

As you take the glow plug out, there is a ring on the plug that you must not lose

With your glow plug igniter, check your glow plugs. Pull the igniter open and place the tip of the glow plug in. Careful when doing this since you may touch the filament and damage it in the process. When the glow plug filament turns glowing red, it is good but if it remains black or unlit then it has already gone bad.

Replace the old glow plug with a new one using the same 4-way wrench tool. Gently screw the glow plug back into the piston. Tightening it can only damage the glow plug and may only dampen the performance of your vehicle.

A glow plug is used to ignite the engine of the race car. If the glow plug fails, your engine won’t be able to start at all.

Redcat Racing Tutorial – Tuning Your Redcat Engine and Understanding the Carburetor

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

This Redcat Racing tutorial covers tuning your RedCat  engine and understanding your engine’s carburetor. This is a part of a series of tutorials that instructs first time users on the function of a carburetor and tuning the engine afterwards.

It is important to remember that tuning a 2-stroke engine may require skill and patience. You will have to learn skills and a few tricks in tuning a race car engine easily and efficiently. The amount of fuel and air that goes into an engine for burning affects the overall engine performance and all of these are controlled by the carburetor. You need to set the carburetor properly to give the engine the right mixture of air and fuel to burn. This is the tuning process.

There are several terms that you will hear and use as you tune your engine:

  • Rich means that there is more fuel, less air mixture. This process can keep your engine run cooler with more lubrication but will also decrease the engine’s performance in the long run.
  • Lean on the other hand means that there is more air and less fuel in the mixture. You will get more power in your engine and more performance but an engine running lean won’t last longer.

Understanding the parts of your carburetor will help you get to know more about its functions. This carburetor slide open sideways, there are several types of carburetors and each one may be different from each other.

The idle speed screw controls the air and the fuel mixture when the engine is set on idle speed.

The HSN or High Speed Needle controls the air and fuel mixture when the carburetor is opening from partial to a full throttle speed.

carb hsn

The LSN or Low Speed Needle controls air and fuel as the carburetor is set from idle to partial throttle speed.

By turning the screws on the needle controls of the carburetor clockwise, you close the High Speed Needle which means leaning the High End. When you turn the screw counterclockwise, you are opening the High Speed Needle which means to richen the engine. Make appropriate changes by making small turns usually ¼ turns even when you are opening or closing the High Speed Needle.

Set the idle speed screw so you can get rid of engine revving and when you want to fix a vehicle taking off right after the car’s engine starts and engine shutting when it is set to brake. Turn the radio on and power the car on. Take your air filter off and set the throttle trim to close the carburetor. Power off the car.

Always set the high speed needle first, you should see visible smoke from the exhaust. Perform tests setting the High Speed Needle and listening for the engine sound. Take note of the difference between a rich and a lean engine. A Pinch Test would help you determine the richness and leanness of your engine.

Redcat Racing Nitro Engine – Standard Engine Breaking In Procedure

Written by Jason Scott. Posted in Radio Control Cars & Trucks, RC Zone

How to break in your RedCat Racing remote control engine.

This is an essential step that will help you get to know your RedCat Racing engine and how to break in the engine especially when it is your first time to use it. Place your remote control car on a base (or Redcat work stand) to prevent the wheels from touching the ground. Fill the fuel compartment with RC fuel using your plastic fuel bottle.

Redcat Nitro Fuel in Engine

Always turn the radio controller on first before you power the receiver on the remote control car. With your fingers, block the exhaust system and with your other hand, pull the started to start priming the engine.

With short pulls, you should see the fuel in the fuel tube from the fuel compartment go to the carburetor. After a few short pulls, use the glow plug igniter, insert it to the glow plug located in the piston and pull the pull starter again. The engine should start immediately.

Insert glow plug igniter and pull starter

Set your remote to idle speed so that your wheels are not moving. If the wheels are moving, check the throttle trim from the radio controller and set it on idle. You may also use an idle speed screw to do this manually.

It is recommended that you allow the engine to sing for a full tank. Give the car a full 15 minutes break and then fill the tank again for the second process.

After you have finished a full tank, it is time to drive your car. The first thing to do is to make 8 circles on ¼ throttle. Make circles of 8 several times. Once the second tank of fuel is finished, let the engine cook down for 10 minutes.

Fill the tank with fuel and do what you have done on tank 2. Allow your engine to rest for 10 minutes before you start on tank 4. This time, drive your car doing 8 circles on half throttle. After the 4th tank is finished, let the car rest for another 10 minutes to cool the engine down.

When you are on tank 5, drive your car on a straight line going from partial to full throttle this time. Keep doing this until you have finished tank 5. Let the engine cool down for 10 minutes.

Now you can do whatever you want!

Install the fuel filter before starting the engine.

 

Fuel Filter for Nitro Line

The fuel filter will be set in place at the fuel hose that runs from the fuel tank to the engine.

Cutting Fuel Line on Redcat Racing

With a cutter, cut the hose to make room for the filter; slide the one end on the hose and the other end to the hose that runs to the engine.

Fuel Filter in Nitro Line

A fuel filter will protect your engine from dirt damage from contaminated fuel.

Fill up the fuel tank with RC fuel with the nitro bottle that came with your Redcat Racing Ultra Nitro Starter Pack or Nitro Tool Kit. Open the fuel compartment located on the remote controlled car. Fill the tank but not to spill over.

Filling Up a Redcat Racing Nitro Fuel Tank

Pull the starter very gently, in short bursts. Always secure your car with one hand as you make short starter pulls. Do not pull the cord way out like a lawn mower. If this is the first time that you are starting the engine, its best to prime it first. You may place a few drops of nitro fuel in the carburetor and a few drops of oil directly on the glow plug which is located inside the piston. Then pull the starter loosely to make sure the fuel goes in.

The pull start may be very hard to pull in a brand new engine. Do not force the pull start and always have a firm hold on the car when you are pulling the pull start.  As the car powers on and the engine starts, let the car “sing” for at least one fuel tank. The engine may quit for a few times, just set the car on idle speed by trimming the throttle with the use of the remote. Do not rev the engine.

Standard Break In Procedure calls for 5 Tanks on Idle. There should be smoke coming out from the exhaust if there is no smoke, then you are running the engine too lean. You have to make adjustments otherwise you will risk damaging your engine.

Check the engine temperature during the first run by touching the top of the blue piston It is normal to see fuel spitting from the exhaust when you are priming your car for the first time.

Remove the cover of the battery compartment of the car. Examine the parts inside. It has a battery holder and a 2-channel receiver (channel 1 for throttle and channel 2 for steering). Check the connections, any loose connections will lead to problems in controlling your car.

Redcat Racing Battery Compartment

The receiver also houses the frequency crystal that helps to lock on to a specific frequency from the radio controller. If you want to change from one frequency from another, you can simply pull out the frequency crystal from the receiver and change.

Slide open the battery compartment of the radio controlled and insert 8 AA batteries on the compartment. Place 2 AA batteries on the battery compartment of the car and place tape or a rubber band over the compartment to prevent the batteries from falling out of the compartment due to engine vibrations.

Always Power the radio on first and then turn on the power on the car. Then check the controls accordingly. If controls are reversed, you may adjust them by using the reversing switches located inside the advanced panel on your radio receiver.

Install the antenna cable on the car. The antenna for the car is located inside the plastic of the instructions manual. The battery compartment of the car has the wire for the antenna connection; unwind the wire and remove the top part of the antenna. Slide the wire into the tube and once every inch of the wire is in, place the tube on the hole provided located on the battery compartment. Replace the rubber part of the antenna.

Examine the air filter. It has two pieces of foam, remove it and place a small amount of air filter oil. A tip is to apply the oil on a clean surface and just gently allow the oil to penetrate the foams. The Proper amount will leave oil on your finger tip after you stroke the filter.  If you squeeze the oil filter and it drips, you know you have used too much.

Replace the foam back. Placing oil on the air filter can reduce dirt from going into the filter and ruining your race car engine. You can wash these foams and dry them should they become very dirty.

Air Filter Oil

Apply Loctite glue on all surfaces that are prone to vibration damage when the car is moving. The most important part of the car that needs Loctite is the 4 engine mounting screws at the bottom of the vehicle base plate. You must also apply Loctite on the 4 screws of the central differential gear box located at the middle of the plate.

Loctite Screws Redcat Nitro

Take one screw at a time and apply Loctite on the screw and then replace it back

The parts of your race car that heats up are your nitro engine which is near your exhaust manifold. The throttle circuit is located near the exhaust area and this controls your car’s breaking system. The disc brake system is attached to the central gear box facing the throttle. The battery compartment is a large box located near the throttle system where there is a large on and off switch to power the car. Removing the air filter (a circular attachment at the center of the engine) will allow you to examine the carburetor.

There are several valves in a race car carburetor and understanding how each valves work will help you get to know your car’s engine performance better.
