Kyosho Inferno NEO 3.0 Review

Running In The Kyosho NEO

Having grown up around RC’s in my younger years, you get to know the pitfalls of RC Car repairs and the jackasses in the industry who try to take you for a ride, especially when it comes to buying parts for a Nitro car.

 

I have bought a number of RC Cars through Hobby shops or online and the only time Hobby shops ever see my face is when I buy the car and pretty much only for fuel from there on and maybe a glow plug.

 

What Hobby shops don’t see me for:

  1. Broken RC Ring gears
  2. Busted RC Gearboxes
  3. Broken diffs
  4. Prematurely worn out engines from loss of compression from running STUUUUUPID levels of Nitro
  5. Blown rods from severely running lean mixtures or ridiculous concentrations of Nitro
 

Would you like to know how this is possible? Read on and you will pick up a couple valuable pointers, especially from our review on the Kyosho Inferno NEO 3.0

 

Anything else that is not drive train related will be having an accident and breaking control arms or shock towers, but not engines and gearboxes.

 

I understand that RC Hobby shops need to make a living and I am all for that but business today including Hobby shops can become an excessive expense on our lives if you do not exercise some care when it comes to your RC Nitro Car.

 

Having said that, our Hobby shops do need our support so wherever you can support them, please support them, after all, we don’t have parts for our cars if our local hobby shops shut down on us so support them while you can. My services included are all about support of our industry as a whole.

 

Back in my day of learning on some pretty crappy models with cheap plastic parts and cheap Nitro engines made in Taiwan, I ended up paying very many visits to the local hobby shop which back then was Hobby World in Hurstvile.

 

A Quality RC back then was still over 1000 dollars which was unaffordable for most of us and still is for many, so you had to do with second best.

 

I got to know one of the young lads back then who happened to be highly knowledgeable when it came to nitro engines and he knew a lot about diagnostics.

 

I learned a lot from him when it came to bad quality engines which were nothing more than a headache out of the box with carby leaks, crankcase leaks or even air leaks through sealed bearings.

 

Basically, what I am saying is that a bad engine will make you an expert in diagnostics.

 

After all, an engine that is really good will not underperform, so how will you learn anything?

A little more information About The Kyosho Inferno NEO 3.0

The Car

Basically, this is an out of the box ready to go race car. Built into its DNA is a very real 8 world championship wins which says a lot about this model RC Car. This car is basically hassle-free performance right from brand new out of the box.

The Engine

The KE21SP Donk is an absolute animal of an engine that just wants to let rip even with a run in tune.

The Shocks

This virile animal is equpped with pretty strong shocks coming into the scene with big bore shocks that come with 3.5 mm thick shafts for the tuff stuff and also includes a 5 mm MP7777 front shock tower

The Tyres

When it comes to getting that grunt to the ground the rubber is KC Motocross tire. The tires have been chosen for various types or multiple types of terrains, rather than committed to one surface.

Performance Servos.

Now what good is all this performance stuff if you can’t steer it effectively around corners in all weather conditions and accelerate and brake it at the same time? Of course.

Kyosho thought of this and equipped the NEO with high response, torquey water proof servos being the KS5031-09 MW servos.


This unit is a formidable opponent for any competitor for practically all surfaces when set up for the right surface. Money well spent indeed.

 Completing the package is the high-response and torque water-proof servo, KS5031-09MW, ensuring precision control.


This vehicle seamlessly combines racing prowess with off-road dominance, providing accessible high performance for all levels of enthusiasts.

Everything I know about nitro engines to today is all because of diagnosing bad quality engines.

This is what leads to understanding when a Nitro engine is talking to you when it runs. It tells you if it is lean or if it is rich, whether it is at idle or screaming down the straight at full song. Yes, it has been an adventurous 30 year stretch.

Breaking In The NEO 3.0

Neo 3.0 Tuning

Moving on from Hobby shops, I received a call from a young lad in Hurstville who wanted some assistance from an independent expert and not a hobby shop.

 

Justin was concerned about his brand new Neo 3.0 and how it ran for a little while when he started it, and after about a couple tanks, it suddenly stalled, and it would not start whatsoever. So the run-in process was stopped short.

 

I own the NEO 3.0 in the top right corner image or the one to the left of the image here.  I purchased it just less than a year ago and still have not had time to run it.

 

Still brand new out of the box and collecting dust, so when Justin called me telling me he was having issues with his, I saw this as a good opportunity to see first hand what the NEO 3.0 was like so I eagerly as always jumped at it. It also gave me an opprtunity to do a review on the Kyosho Inferno 3.0

 

This would be a good opportunity or a review of the NEO 3.0 Kyosho seeing I had not started mine yet.

 

I had instructed Justin over the phone that considering the issues he was having that I needed him to stop at his local Hobby shop and pick up a new hot glow plug. Trust me when I say this comes from experience with glow plugs.

Nothing out of the ordinary. I have never had much luck with the factory issue glow plugs and being cold plugs, they don’t seem to keep a new engine running long enough, so I instructed him to pick up a new hot plug and  16 percent Nitro.

His local Hobby shop for some reason didn’t know what a hot plug was so they gave him cold plugs instead. What can I say?

A hobby shop that sells nitro RC Cars, did not know what a hot plug was. Am I really that old or am I not using the right lingo these days?

On top of that, they were insisting they sell him 20% nitro which is not really necessary for a street muck around Kyosho with no intentions of racing it.

 

The stronger the nitro, the less lifespan of your engine and the more broken driveline parts. This is where a hobby becomes expensive when you push beyond the limits.

 

Now you know why hobby shops like to to sell stronger nitro right ? Anyway, moving on, he got the Nitro but the wrong plugs.

 

When Justin arrived, I asked some preliminary questions about tuning needles being mucked around with which he hadn’t touched so I said, let’s just check the glow plug and make sure it’s working. I took the glow plug out and checked with the glow driver and sure enough, she was glowing.

 

I refit the glow plug back into the head and proceeded to fire this bad boy up. At every few pulls, I would richen the mixture up to get it to fire. Idles were set correctly so there was no reason it should not fire provided everything else was working. But was everything else working ?

 

This continued until I could feel the engine was more than receiving fuel, as it was turning over much easier. This is an indication there is fuel in the crank case. An engine with no fuel in it is very dry and ramps up tight when turning it over, because it is has no fuel in its crankcase. I immediately realised the problem was the glow plug. I removed the glow plug, refitted a hot glow plug and she fired within three pulls.

Kyosho Neo review

Now one would ask, ” if it was working in your hand , then why not in the engine ” Simple really. Being a cold plug, it worked fine in your hands with a glow driver but as soon as cold fuel hits the glow plug in your engine, it blows it out and your engine never starts, not to mention that we are running under 20% nitro so a hotter plug will glow easier. Cold plugs have a short glow wire, which is also thicker. It will not take much to blow it out with low percentage nitro as the heat needed to glow the plug just isn’t there

 

 

It may work fine when new but as soon as it ages just a little, it blows out from cold fuel and does not glow anywhere near enough to fire over the engine. This is where the extra filament and thinner element wire helps in a hot glow plug as it retains heat longer.

 

It is why it is the much better bet for low nitro base, standard compression engines. When I buy a new Gas car, the first thing I do is piss off the glow plug and change it with a hot one. I do not even waste my time with cold plugs unless I am planning on running 20-30% nitro or increasing the compression of the engine. Hotter plugs under these conditions will not last long at all. This is where you use cold plugs but in your standard fuel range and standard compression low nitor % fuel range, a hot glow plug is best.

 

 

If you ever encounter and issue where you are certain your engine is receiving plenty of fuel but not kicking over, you can bet it is your glow plug.  Replace it with hot plug and you should be out of the woods.

 

 

Moving on from glow plugs, I then continued to run the new engine with another two tanks of which it only needed. I could see as time went on the motor was freeing up nicely.

 

After about half way down on the fuel tank, I brought this bad boy in and richened the top end fuel needle a little more to ensure the engine was getting plenty of lubrication. A few more passes and the engine had freed up and the animal was beginning to come out of this gas car.

What Did I Think Of The Kyosho Inferno 3.0?

My Personal Thoughts After Running In

Being a Kyosho product which is robust and durable gas car, Kyosho was claiming this engine to be from what I remember the most powerful .21 engine of its time.  I ran the engine in just fine and with even rich mixtures I could see this engine wanted to scream.

 

Even while cruising past us on a run in tune, I would intermittently flatten the throttle and it would instantly fry up all fours for a short period of time, and this was with 16% nitro on a run in tune.

 

This gas car was producing serious power with traction issues on 16% nitro  on a run in tune and the hobby shop was trying to sell this poor guy 20% nitro. This just explains that even 10% percent nitro for street use would be more than enough power while maintaining some traction.

 

Of course, suspension and tyre alterations would play a significant role in traction, but when it is letting go easily enough the way it was, it really does not need anything stronger than 16% nitro.

 

 Once the motor was run in, I let the fuel tank go to half tank which is the ideal fuel pressure for proper tuning. I richened it up that little bit more so by the time the tank would go near empty, it would have leaned  that little bit more.

 

Of course, on full tank it will run that little bit richer, but richer is safer than leaner any day of the week. This tuning set will see this engine last a long time if it stays on 16% nitro.

Final thoughts On The Kyosho NEO 3.0

Kyosho Neo 3.0 Review

Once the run in procedure was done, we slowly started to check out all the other features of handling, braking and power of course.

 

The handling out of the box is set up pretty good for handling but if you are planning on racing this car, there will be some more adjustments depending on the course you are running with your choice of shock systems, toe adjsutments and of course your choice of tyres for the race.

 

For the street however, there is more then enough goodness for a reliable running gas car. The braking is spot on for stopping power.

 

I personally could not be happier with its braking capability on stopping power. Full brake will slightly lock the rears while maintaining grip.

 

It’s radio is quite simple to use and uncomplicated. One thing I hate is complicated to use equipment. The radio is simple to understand in its function, as everything stares at you in plain writing. You do not need to go looking for it like you do with digital radios.

 

Power is another thing. For 650 bucks with a radio and RTR gas car, you could not be happier. This thing packs quality with performance and serious punch out of the box.

What was outstanding was the quality of the idle and throttle response even with a run in tune running rich mixtures.Very nice low idle with no air leaks whatsoever to interrupt the quality of the tune.

This Kyosho does not hesitate in moving its ass even with rich mixtures which is a HUUUUGE plus. You do not have to run it lean, and you have plenty of power for the street or dirt to have fun with it.

 

This engine has loads more grunt on tap when you decide to lean it off even on 16% nitro….if you can keep it in a straight line.

I set the mixtures to slightly richer for this young man so it would continue to start just in case of a change of weather, and it still hammers while providing plenty of lubrication.

 

I think Kyosho can claim to fame with ” it is the most powerful 21 developed for its time”…and I have not even started mine yet.

One thing to check on is the air filter. If you buy one of these, do not forget to oil up the oil filter

 
 
 

Hopefully, if and when I get some time among my other gas cars I may get around to one firing up my on NEO 3.0  Bang for buck, you can’t ask for a better quality car. The race version is over a grand out of the box and you gotta add everything else. This one is out the box ready to go with a good chassis and great drive line with an engine that packs a wallop for power delivery.

 

It is about as honest a review on the Kyosho Inferno 3.0 that I can give and I don’t easily give high reviews of products. Compared to everything else that is out there, the Kyosho Inferno 3.0 is a clear winner when it comes to performance vs cost. The one thing I always advise with any gas car when you buy it new is to lock tight all the screws under the chassis and wheels. Nitro engines emit vibrations throughout the chassis and these vibrations will loosen off already loose enough screws, nuts and so forth causing damage or loss of parts, so before your new Kyosho, go over all the screws and nuts to ensure nothing comes loose while running it.

 

The best way to avoid repeated visits to hobby shops for parts is to apply a little patience and go over your new gas car and tighten all parts. Also remember that anything about 16% Nitro and above running lean mixtures will begin to break parts and make your gas car unreliable.

 

Broken gears or gearboxes will be common, forcing you to spend more money custom making metal gears which are unnecessary.

 

On top of this, you have blown engine parts in the pursuit of more power. Exercise some care, common sense, and you will find your gas car will last you longer than you think without repeated visits to the hobby shop. It is all business for hobby shops. Always support your local hobby shop, but also understand that common sense in unnecessary expense is also required if you want to enjoy this hobby without breaking the bank.

Back in my days in the 90’s when I use to race my Inferno, you could not buy anything like this for under a grand. Now you can buy Kyosho and basically go racing out of the box for 650.00 dollars for some fun on the dirt tracks. If you are planning on buying a Kyosho Inferno NEO 3.0 without spending big dollars, you will be impressed with this gas car. I hope this Kyosho Inferno NEO Review has helped and if you have any questions, please feel free to reach out.
