Redcat Racing Tips – How to Remove a Redcat Nitro Engine

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

This is a RedCat Racing tutorial showing how to replace your race car’s important parts especially when these parts are damaged or require maintenance and cleaning. Probably the most important of a car parts is its nitro engine.
It is very easy to remove the nitro engine, especially when you have the right tools at hand. The engine may need to be removed for additional repairs, cleaning, or just regular engine maintenance before and after a race.

First, Remove the 4 screws from the chassis.

You can already take out the engine and to whatever you want with it. You can have it repaired, maintained or cleaned. It is recommended that after every racing, your nitro engine may need rest especially if it is the first time the engine will function.

Place the engine back by screwing it first on the manifold before connecting it to the fuel hose and exhaust tubing. Make sure everything is in its place before you prime the engine again.

If possible, run the car in one full tank then allow the car engine to rest for 10 to 15 minutes. Then you may replace nitro fuel back then allow the engine to work for another full tank. Allow the engine to rest for another 15 to 20 minutes.
Engines are repaired easily with the use of nitro fuel, rags and other maintenance and appropriate cleaning agents. Never use corrosive cleaning materials to clean your engine.

Redcat Racing Reviews and Tips – How to Replace a Broken Pull Start Part II

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

This is a RedCat Racing tutorial covers maintenance and repair tips for your radio powered nitro engine. This is one of the many RedCat Racing training tutorials; learning about these repairs and simple troubleshooting processes will allow you to personally replace or repair a broken manual pull start.

A broken coil of the race car pull start is indeed a headache. No matter how you pull the manual pull start, you will never be able to start the engine when the thin metal wire is broken. Take apart a pull start by removing the safety covering of the assembly. Take all the other parts. You must be very careful with the fixed metal strip located inside the pull string assembly. So you won’t inure yourself or cut yourself with it, take out the coil very slowly.

Presuming that the cord for the pull string is still intact ad that the only thing broken is the coil, you may get a new one. Simply take the cable out slowly and reshape a new one to take its place.

Bend it accordingly and coil everything slowly (using needle nose pliers) . The easiest technique is to start as a big circle and then start pulling the coil outwards. This is very tedious process but take time to shrink the coil into a very small circle or simply small enough to fit back the pull start.

Redcat Racing Broken Pull Start Coil recoiling

Use nose pliers to place the string safely into place. Place the pulley system back, recoil the string to the coin and then you are ready.

Redcat Racing Reviews and Tips – How to Fix a Broken Redcat Racing Pull Start

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

This is a RedCat Racing tutorial about the common troubleshooting tips in maintaining a RedCat Racing vehicle. Breaking the pull starter is one of the most common problems that even professional racers encounter every day. Learning how to replace and repair a broken pull starter will help you take care of your race car more effectively

A broken pull start is one of the most common problems. A broken pull string will never be able to start an engine so it is better to replace one in a hurry. Before working on your pull start wear protective eye wear or goggles.

Remove the engine from the manifold by unscrewing the 4 screws at the bottom of the car. Remove the pull start by removing 4 screws that connect it to the engine. If you do not know how to do this, see our article on “How to remove a nitro engine”

The pull start is composed of the string, a coin that houses the coil and with a nut shaped middle and a long, thin, metallic coil.

Redcat Racing Reviews and Tips – How to Deal with a Flooded Engine

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

This is a RedCat Racing tutorial that will teach you how to manage and troubleshoot common maintenance and assembly problems. This video is one of the many RedCat Racing tutorials that teaches hobbyists about dealing with engine problems. A flooded engine is one of the most common concerns for users and here is a step-by step guide to deal with it.

A Flooded engine is a very common problem especially when you are priming your engine for the first time. u can easily tell that the engine may be flooded when your pull string does not pull properly. Usually, only a few short pulls would be able to start an engine up. It is very important to be patient and only apply a couple of short pulls to the engine, otherwise you would either flood the engine in the process or you will only snap the cord of the manual pull start assembly.

Never force a pull start that will simply not work. It will only snap the cord and even damage your engine all the more. Remove the glow plug from the piston with the use of the redcat racing nitro tool kit.

Replace the glow plugs back with the 4-way wrench. Restart the engine with just two to three short pulls and with the glow plug igniter in place. This will surely start the engine in no time at all. Remember to gently replace the glow plugs in to prevent damage on the threads inside the heat sink.

Check for the exhaust smoke and a few amounts of fuel that may come out of the exhaust. This means that your engine is running rich.

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.

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.

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.
