How To Break In A Nitro RC Automobile – The Full Information (With Footage!)

If you’re studying this text, likelihood is that you simply simply purchased a nitro RC automobile and wish to begin utilizing it. However earlier than that, one of the vital vital issues that you will need to do to make sure your RC automobile lasts so long as attainable is correctly breaking the engine in. So since there appears to be a variety of misinformation on this matter, I made a decision to make an entire step-by-step information on the easiest way to interrupt in a brand new nitro RC automobile.

Breaking in an RC automobile is definitely a quite simple course of. Primarily, you simply want actually to let the oil contained in the nitro engine lubricate it. However anyhow, comply with this information if you happen to aren’t positive how to take action. I additionally present a couple of additional assets equivalent to what to do in case your automobile received’t begin within the first place.

Step 1 – Familiarize Your self With The Inner Elements And Get Every thing You Want!

The very first thing to do is to familiarize your self with most, if not all of the parts inside your RC automobile. In case you have purchased a very new mannequin, then it is likely to be a sensible concept to search for an in depth clarification of all of the parts within the guide that comes with the automobile. However it’s essential to know the place is the gas tank, the exhaust, the air filter, the pull-start, the carb needles and the glow plug.


After that, have the whole lot wanted to interrupt in your new nitro RC automobile. You’ll want a quart of nitro gas, a number of glow plugs, a glow plug igniter, and AA batteries for the transmitter and the controller. In case your RC automobile is new, then you’ll have to purchase a starter equipment, which can comprise most of these items inside.

Step 2 – Insert The Glow Plug And Activate The Electronics

For the second step it’s essential to set up the glow plug contained in the engine. Almost certainly your RC automobile comes with a glow plug already, however since they are often so frail it’s a good suggestion to have additional ones in case that one doesn’t work. Anyhow, for this step, you’ll be sure that the glow plug is working by utilizing the igniter, which comes with the starter equipment that you simply purchased. The brighter the glow plug, the higher. After this, use the wrench that got here along with your starter equipment to screw it to your engine. Keep away from over-tightening the glow plug, they’re very frail!

Be sure your glow plugs are sizzling and brilliant earlier than inserting them onto your engine

Step 3 –  Fill The Gas Tank With Nitro & Prime The Engine!

After step 2, It’s time to start out priming the engine. To begin with, just be sure you set up a working glow plug contained in the engine. After this, merely fill the gas tank with nitro till it’s nearly fully full and shut the lid. After this, you’ll block off the exhaust with considered one of your fingers or with a material after which begin calmly however firmly pulling on the pull starter. That is referred to as priming the engine, and it’s the best way that you simply begin distributing the nitro gas into the motor itself.

You solely want to drag the pull starter a couple of instances (not more than 5 yanks kind of) keep away from pulling an excessive amount of or else you’ll flood your engine, which implies that the engine is totally crammed with nitro. A flooded engine could have a really onerous time beginning, and the pull begin will probably be very onerous to drag.

Attempt to keep away from yanking the starter an excessive amount of or else you’ll flood the engine.

Additionally ensure you don’t yank too onerous, or else you danger ripping the twine off the automobile. If the pull begin is excessively onerous to drag, then that most likely implies that you flooded the engine (Under I present a information on find out how to repair this).

Step 4 – Begin The RC Automobile Up And Let It Idle

After a couple of yanks, it’s time to truly begin the automobile. You’ll stick the glow plug igniter contained in the engine whereas pulling again on the igniter. You need to have the ability to latch the igniter into the glow plug inside, igniting the glow plug within the course of. Whereas the igniter is inside, begin yanking the pull starter once more, however this time you’ll go away the exhaust opening uncovered. After a couple of yanks, the automobile ought to spring to life. You possibly can take away the starter after the automobile begins up.

After priming the engine, insert the igniter contained in the automobile and begin yanking the pull starter! The automobile ought to begin up after a couple of yanks.

Now after this, a couple of issues can occur: both the automobile dies after a second, the automobile will speed up ahead, or just the automobile stays as an alternative. If the automobile dies after a couple of seconds, then that implies that the idle screw is ready too lean and it’s essential to do some tuning of the carburetor. If the automobile received’t cease accelerating as quickly as you begin it up, then the other is true: the automobile idle screw is manner too wealthy. Both manner, it’s essential to get your screwdriver and begin tuning the idle screw.

If the automobile stays working then excellent! simply go away it’s for a couple of minutes. As quickly because the motor begins working you’re breaking it in. I might personally advise that you simply go away the automobile working for about 10 minutes or till you burn via half a tank of nitro. We go away the automobile working in order that the nitro lubricates the motor as a lot as attainable.

Step 5 – Cruise A Little Bit

After 10 minutes or so, it’s time to hit the throttle a little bit bit. As an alternative of letting the automobile idle, you at the moment are going to cruise a little bit bit with the automobile. Keep away from hitting the throttle too onerous, simply apply sufficient throttle in order that the automobile picks up a little bit little bit of velocity. You’ll let the automobile cruise for about 10 minutes, permitting it to construct up some warmth and letting the nitro oil lubricate the motor’s insides. Once more, DO NOT hit the throttle too onerous, otherwise you most likely will cut back the engine’s life, and even worse, you may harm your RC internals.

I might suggest that you simply calmly speed up the automobile till you undergo about half a tank of fuel. After this, progressively begin making use of extra throttle. The automobile is damaged in after you undergo a couple of tanks of fuel.

What To Do If Your Automobile Received’t Begin?

So if you happen to tried to start out your automobile and it didn’t keep on for quite a lot of seconds, or if it didn’t begin in any respect, then it’s most likely as a result of considered one of 2 causes: both the engine is flooded or the carburetor is just not tuned correctly. Test under for troubleshooting directions.

Motive # 1 Why Your Automobile Is Not Beginning: Engine Is Flooded

That is the most probably cause why your automobile is just not beginning: you most likely overprimed the engine and now it’s chock filled with nitro gas, and it’s essential to unflood it. If that is so, then the pull starter will probably be actually onerous to drag. Observe the next steps to unflood your engine:

  • Take away The Glow Plug: The very first thing is that you will take your wrench and take away the glow plug. Ensure you additionally take away the copper half inside.
  • Flip The Automobile Upside Down & Begin Yanking The Pull Starter: After this, you’ll flip the automobile the other way up and begin yanking the pull starter a number of instances. 2 issues will occur: The pull starter will probably be MUCH simpler to drag, and likewise there needs to be a liquid (nitro) squirting out of the engine and the exhaust. If this doesn’t occur, then your RC automobile is just not flooded and you must take a look at the following step. But when it does, merely yank the pull starter till there’s no extra liquid dripping out of the automobile.
  • Screw The Glow Plug Again In: After eradicating all that additional gas, you’ll screw the glow plug tightly. The pull starter needs to be a little bit bit looser than earlier than. Beginning up the automobile needs to be a lot simpler this time.

Motive # 2 Why Your Automobile Is Not Beginning Or Shuts Off Quickly After Beginning: Your Carburetor Wants Some Tuning

In case your automobile shuts down after a couple of seconds of beginning it, one of many the reason why this is likely to be occurring it’s due to improper carburetor tuning (too wealthy or too lean). Observe these steps to repair this:

1. Familiarize Your self With Your Carburetor & Its Needles

To tune your carb, you employ 3 needles: the high-speed needle, the low-speed needle, and idle screw. The situation of those will rely between RC vehicles, however under there are a couple of footage of the place they’re situated in my Exceed Forza.

The high-speed needle controls how a lot air enters the engine when the throttle is hit onerous. The excessive velocity needle is the best to search out and 99% of the time the screw is roofed by a yellow brass casing. Additionally, it’s nearly all the time discovered close to the engine or the carburetor itself.
The low-speed needle controls how a lot air enters the engine when the automobile is gently accelerated. The low-speed needle is tougher to search out, but it surely tends to be discovered on the other facet of the high-speed needle.
The idle screw controls how a lot air enters the engine whereas the automobile is stationary. The idle screw can be fairly onerous to search out, however its normally very near both the excessive velocity or low-speed needles.

2. Examine The Opening Hole Inside The Carburetor

As you learn above, the idle screw is the screw that controls how a lot air enters the engine when the automobile is idling. In different phrases, it controls how lean or how wealthy the automobile runs when idle. In case your automobile is shutting off quickly after beginning, then most likely the idle screw is likely to be set manner too lean. It is likely to be sensible to verify the opening hole contained in the carburetor opening.

To verify the opening, you’ll take the air filter off the carb. It ought to appear like this:

The hole shouldn’t be quite a lot of milimeters vast.

The hole shouldn’t be quite a lot of mm vast, and if its wider than that, then you’ll need to tune the idle screw. You’ll get a screwdriver and barely flip the idle screw counterclockwise to closen the hole, similar to within the image under.

Ensure you don’t overturn the screw as a result of it’s very delicate. I personally would suggest that you simply flip the screw in hour increments.

After you do that, strive once more and begin the automobile. You need to have a better time now. Nevertheless, if as quickly as you begin the automobile it begins accelerating, then you definitely most likely overturned the idle screw. Carry out the required changes till the automobile stays as an alternative when began.
