[Mr. Schumacher]

How about a Mini Kyosho "GIGA CRUSHER" Monster Truck?

[Tamiya4ever]

Oh wow. I was always thinking of a mini truggy. Now I would just love to see a mini dual belt sedan :D But its very nice. I guess I may get this to add to my RC18T.

[crazyjr]

Here we go again with the mt/truggy war

[Tamiya4ever]

Here we go again with the mt/truggy war

Actually as I see it. The RC18T and Losi Mini are Stadium trucks. The Hotbodies MiniZilla, PTI and Duratrax are MT, and the new Inferno is a truggy.

[Wosstifer]

That thing is the shizzzz. Thank god it comes with oil shocks. the mini inferno's oil shox were like $80 for four

[Rain Man]

No shots with the body off?

[rckid11]

I need a kit!!!!

[elite]

Id also love to see the layout!

I like the shocks , smart move. also the adjustable toe, caster, etc makes it more racable - which its cool! All things I did to my rc18t but if this thing has it, awesome...and if the suspension is beefy, and its more 1/16th itll be awesome.....assuming itll do what the 18t will with the mamba :) (speedwise)

I initially read soso things about the speeds and mambas but make this will be a totally different who knows.......letssssss seeee inside???

[rckid11]

Same layout as the buggy.

[Rocksolid_X1]

I can't wait for more pictures to come along as well as some different paint schemes to mix it up a little.

[chris1]

That will look good next to my mini inferno

[Natedog]

MMMMm, I need one o these too!!!

[nitroracer4600]

me want!!!

[dj_ski69]

Here we go again with the mt/truggy war
Call me crazy but it looks like a 4wd Stadium Truck to me....
Never heard ne1 call the RC10T a truggy...And all it essentially is, is a buggy with bigger tires ect....
I really don't get it....Even people call the Lightning "Stadium" Truck a truggy..

This little ST is might be awesome....But like anything Kyosho the price is gonna be high...Over here in Japan the pricing on these come out to a whopping 26,429 Yen....which is about 250 Bux....(depends on the yen rate)
Just not worth it in my book.... And I don't expect the price to be that much lower when it becomes available for sale in the states....
But anything would be an improvement over the Mini Inferno which is one of the worst stock designs I've ever seen....
The amount of money needed to be spent in order to improve the Half 8 is dumb...Also it looks like they stuck with the AA battery scheme....My Grandma can run faster than this...Looks like the ST will be a bit better out of box due to the diff and shock upgrade...
Bahh....
Here is some more looks at the truck HERE (http://www.kyosho.co.jp/web/products/car_bike/half8/mini_inferno_st_ready/mini_inferno_st/mini_inferno_st-e.html) and HERE (http://www.kyosho.co.jp/web/products/car_bike/half8/mini_inferno_st_ready/lineup/lineup-e.html)

[Duster_360]

Any body know if these electronics are the integrated type where the ESC and servo are made together?

I'm with rckid11 - need a kit - offer it both ways!!

[2fast2slow]

But will a Mamba 8000kv fit, is the question?And can the 6 AA be replace with a 6 cell battery pack?

[rckid11]

Mamba's are not a good fit for Mini Inferno's. To small. Get a AON 4900 and a Mamba 25 esc and you will be much happier. You can drop in a 10 cell GP1100 pack if you really wanted to ;) .

[rckid11]

Double post. :o

[Pontiacdriver99]

Call me crazy but it looks like a 4wd Stadium Truck to me

That's what a truggy is... a 4WD stadium truck that has been converted from a buggy. And it all fits too.... consider this....stadium trucks are 1/10th scale.... and the mini-t and RC18 are 1/18th, this truck was once the buggy and is 1/16. Buggies are 1/8th scale, bigger then the 1/10th scale trucks, hence this truck is 1/16th, bigger then the 1/18th. It all fits into the scales between the 1/10th trucks and the 1/8th truggies. If there's any car here that doesn't really follow the "rules" so to speak, it's the RC18 because it's 4WD, and stadium trucks aren't 4WD, unless you include HPI's trucks, but i don't think those are legal to race at anything above the club level racing.

[t9dragon]

GS is releasing a 1/10 4wd Stadium Truck.

Does anyone know if the parts are interchangeable between the Half 8 and the Truggy?

[StevePond]

Yes, mostly. The shocks, and diffs (though I'm not 100-percent on the center diff), and suspension arms should be interchangable, although I'm pretty sure the parts needed to convert them will only come after they've made enough parts for production units.

[rckid11]

I am just going to get the diffs, susp. arms, and driveshafts. Then I would have an ultra wide stance buggy :) .

[WhoMe]

Man I cant wait for the East Coast Champs race..Kyosho is supposed to be giving out a few of these mini truggies to the top 3 in half 8 classes at that event.

[StevePond]

Let me clarify this a little bit because we just discussed it yesterday. The top three in the Mini-Inferno class will receive the first three production Mini Inferno ST trucks to arrive in the US. These will be arriving around Christmas time as of the last release estimate, so each driver will definately be getting one of these trucks as you mentioned, but not at the race. They will be delivered to their home as soon as they arrive in the US. There should be a couple production prototypes on display at the race if you want to check them out.

[Wosstifer]

Wheres the east cost champs race?

[WhoMe]

Pottbelly's Raceway in New Jersey. Thanks for the clarification Steve..still awsome prizes! www.pottbellysrc.com

[TimisTim]

Steve, KYOSHO NEEDS A METAL DIFF GEAR OPTION FOR THESE MINIS!! Sorry for the yelling but I have been having trouble keeping the plastic center diff gears from stripping on my 3s lipo brushless system. This seems like the only option to me. Also the only place I have been able to find these gears is from a store in Hong Kong. So it takes about 15 business days :( Other than this my buggy is awesome. I have beat it to death and it just keeps chugging away.

Plastic gears of the mini's size are just not able to handle the higher power brushless systems. I know you are just one man and Kyosho is a huge International company, but is there some petition for the gears that I can start? Its definetly going to be a money maker for Kyosho. Heck if I wanted I could build almost the whole buggy out of aluminum, so why not the gears. I have seen the ball diff conversion, but am not sure if that would help enough so I have been reluctant to drop the $20 on it.

[Kmot]

Steve Pond of Kyosho let me drive the new Mini Inferno ST today on their test track at the iHobby show. The truck is quite an excellent handling mini and the suspension was amazingly active for such a small and light truck.

Here is a link to a site in the states that carries Mini Inferno parts http://shop.tinyrc.com/home.php I have order from them and I usually get the parts in about 3-5 days.

[winning edge designs]

Trying to make the cool little 10 inch truck go 50 mph might bring about some durabilty issues, LOL........Jim

[Tim'sLosi]

Nice...too bad eclips instead of captured hinge pins.

[c0sie]

Trying to make the cool little 10 inch truck go 50 mph might bring about some durabilty issues, LOL........Jim

amen..some people just expect way to much sometimes.

[2fast2slow]

But can a mamba 8000kv fit, if not a good fit what can be done to make it a good fit

[2fast2slow]

is anyone out there

[c0sie]

if the ST isnt out yet....how can we tell you??

[TimisTim]

Well c0sie this question can be answered by simply looking at the model in the pictures. If you know anything about the Inferno buggy you will notice it runs the same motor and the chassis is the same around the mount and steering assembly. Now take into account how big the stock motor is and you can guess that a mamba will fit easily since they are only about 33mm long. I run a feigao 200 12L in my inferno and had to grind the extra metal at the end of the can to stop it from rubbing on the steering assembly, but the feigao motors are longer than the mambas.

Now with that said the mamba wont be the right motor for the job though. As has been said before the mambas are to small of a motor for a larger 4wd model of this sort. They just dont have the torque to get it moving and will tend to heat up to dangerous levels.

[StevePond]

Jeremy won the Potbelly's race with a Mamba. They even went with the smaller motor to make the power more controlable based on my understanding. I think the Mamba motor works fine, it just needs the right gearing.

[rckid11]

The Mamba can heat up quite a bit in a mini inferno. You need heatsinks and/or a fan.

[TimJohnson]

A Mamba will fit in the ST. You will get excesive heat if you use the High KV motor. the higher the KV the least amout of torq. The lower the KV the more torq, creating less heat. But a small fan is still a good thing to have reguardless of what KV motor you want to use.

Steve, I've got a few buddies who are trying to get a 1/18 4WD class going at our local track with their Mini Infernos. They both say that their Infernos are super-dialed and that they love them (one of them even raced it in stock buggy since his XXX-BK2 was broken; he was running in 3rd until the battery dumped). Anyways...the point is that I want to go race with them, and I think this is the rig to have. It looks great, and if the buggy drives like a dream (after some oil filled shocks, a motor upgrade, and a rechargable battery), I assume that the truggy should be just as good. I'm a truck kind of guy rather than a buggy kind of guy, so I want one of these. Any further word on when they'll be available here?

[StevePond]

Sorry Metalry101, I haven't looked in on this thread for a while. Let me check to see the expected delivery date and I'll post it as soon as I have more solid information.

*Photograph shows Tiger Flare (prototype).

The World Championship winning Inferno's DNA runs thick in this half-eight stadium truck!

The impressive performance of the half-eight series is extended to
stadium truck racing with the addition of long suspension arms and
trucking tires in the form of the "Mini-Inferno ST" to deliver a truck racing experience no like no other. The amazing power of the 1/8 World Championship machine is condensed into half its size (1/16). Tough enough to take on any terrain from dry riverbeds to open fields, the new design compact 4-bevel closed-case differential gears can handle the loads from the big tires. Also, just add different viscosity diff grease (sold separately) to make subtle adjustments to diff tension and running characteristics. Only the half-eight can deliver the optimal combination of light-hearted enjoyment with serious racing performance. Experience it now for yourself!

[metalry101]

Sweet. I'll be picking up a yellow one as soon as they're available.

[t9dragon]

Hey Steve,

Do you know where I can get the Mini Inferno ST? I would prefer to by from somebody in the US.

[StevePond]

They will be here on Tuesday! They will start to go out to hobby shops then.

[t9dragon]

I'm located in Portland, Oregon. Do you know of any local hobby stores that will have them in stock?

[StevePond]

Island Hobbies in Portland is an active dealer. Contact them and I'm sure they can put an order in for you.

[RespirologyRC]

Steve I've been considering buying one of these, but am reluctant because of parts availability. I would consider buying one but it doesn't seem that places like tower or stormerhobbies support them; why is this? Also any chances of metal diff gears??

[metalry101]

Tower doesn't carry Kyosho any more because they suck and they screwed Kyosho in the past. Any decent hobby shop should be able to get Kyosho's products from either Kyosho direct, or through HRP.

[fantomas]

I have mine coming from way of hong kong :D

Anyone know if the buggy version shocks, and knuckles are the same size as the truggy??

[StevePond]

Too bad, you can get them here now. ;)

[schenck77]

I haven't seen any here. I was tempted to order one from ebay coming from hong kong too.

[fantomas]

I havent seen any either.. My LHS cant get thier hands on any and I checked ultimatehobbies.com.... can you give us a link?

[StevePond]

Call Ultimate Hobbies. They already have them or will have them by Thursday. They don't have everything on their website. They just arrrived here and should be in hobby shops this week.

[TimisTim]

Any comment on the aluminum diff gears Steve? I haven't had any problems with the center diff since I added some aluminum bits to help with chassis flex but the extra stress has apparently been pushed to the front and rear diffs. I am going through one or the other every other week.

If not.......the ST's diffs look larger, could they be swapped to the buggy?

[StevePond]

I'm not familiar with any aluminum diff gears. The new differentials from the truck will fit in the buggy.

[RespirologyRC]

I'm glad I finished reading the last few posts. I live in the Northeast of the USA, and can't find a Hobby shop near me that sells them. But Steve you mention Ultimate Hobbies, their in CA, I might as well order the truck from Hong Kong.

[StevePond]

I mentioned that someone else should CALL Ultimate because they said they couldn't find it on their website. There are plenty of shops in the Northeast that will have them as well, like Bruckner and RC Madness, but if you want to order it from China, knock yourself out. ;)

[thedoc329]

hey steve, i placed 2nd behind jeremy at the potbelly's race and would like to cash in this certificate. i cant seem to find reagan's card so can you shoot me an email at thedoc329@yahoo.com ? thanks!

[StevePond]

Sure! Thanks for reminding me.

[Mini-TBasher55]

I'm not really into the whole Truggy thing, but I have got to admit that this thing is cool. Theres not much cooler than a miniture truggy! I don't plan on getting one, but it looks pretty sweet!

[hardadz]

Steve
We have supported the Kyosho line pretty well with the ZX5 and parts backup. Those looking for these can contact us at www.evolutionhobbies.com as we will be talking with Tim at Kyosho America about getting these in with the parts to support them. Just have to wait until after next week.

[TimisTim]

@Steve.......I was wondering if there was any plans to produce a metal diff gear option for these mini's? There would be a huge market for them from what I understand. Maybe you could schmooze a tech or engineer.

[StevePond]

I don't know if there are immediate plans, but the truck diffs are now available, which are sealed and can be filled with silicone fluid like the 1/8 diffs.

[dj_ski69]

Hello,
I have had my ST for a few weeks now and absolutely love it...Of course being in Japan helps in these matters....
For those with questions of Compatibility between the Buggy and Stadium Truck, I can answer a few....
Just about every part is compatible between the Buggy and ST....
The following parts are indeed very different...
Of cousre the Drive Shafts are longer...
Front and Rear Shock Towers are different but should fit both...
Tie Rods are longer and so on....
The only complaint I have is the fact that at least Here in Japan I cannot order just the wheels....The tires come with the wheels from Kyosho and are pre glued.....
But Thanks to some clever mods that make 12mm wheels compatibal its not a huge issue...

@Steve.......I was wondering if there was any plans to produce a metal diff gear option for these mini's? There would be a huge market for them from what I understand. Maybe you could schmooze a tech or engineer.
Dude the Diffs on the ST are awesome and really don't need metal gears...They are a world apart in quality than that of the mini infernos....There are a bunch of companies who have made a plethera of mods for the mini inferno....But it took time to build the current stock.....Give it some time and the metal gears for the diffs will be available from likely 2 or 3 third party players in the Half 8 game....

Out of the Box the Mini Inferno ST is everything that Kyosho should have done the first time with the Mini Inferno...
these Japanese guys just love giving spring loaded shocks with thier cars and trucks I understand why but don't really like it....
Either way in the end the consumer wins.....


SkI

[schenck77]

good to hear that you are likeing your new truck. I hope to have one soon (ordered it last week). My only concern is the diffs holding up to brushless power. I dont want to have to rebuild them all the time like my mini lst.

[schenck77]

Timistim,
I think this is what you are looking for...http://www.gpmracing.com.hk/car/page/pop_tc4_34.asp steel gear set by gpm

[auto2]

I got an ST a few weeks ago . Since then I've got the new tekin esc and a AON 4900 motor. a atomic center ball dif and let me tell you this thing is hot!
CAW has an alloy chassis for it and when I'm done I think this just be my favorite mini. It handles the 1/10 scale indoor track just as good as anything. have to lock up the slipper until a better deal comes along and get a ball dif for the center,

[schenck77]

I have one of those caw chassis on the way and my st should be here tomorrow. I think it will be my favorite mini too when i am done. Will be time to sell the mini lst and rc18t soon. I really like the mini lst but the diffs dont hold up and I really think the inferno should be a better racer.

[auto2]

thanks to CAW for all the great work. I ran this for the first time last night and out of the box it went all night,never broke and was too fast. a 10 year old beat me in the A main. He was slow and steady and I was YE HA! upps YE ha! ups! but i had fun. made all the 1/10 scale jumps and I repeat.NEvER BROKE! and that is with letting everybody test it out.

[auto2]

another pick

[auto2]

one more

[auto2]

another

[auto2]

last one

[schenck77]

truck looks good. I have the same chassis and just put the aon in it. Just wondering what gearing you are running? I will be running it with a 7.4volt lipo (thunder power 2100 or polyguest 3100).

[TimJohnson]

HOW much wieght did that Alum Chassis add to the truck!?

[auto2]

it weighs a touch over 2 pounds RTR. ( on a cheap food scale)

I need a set of racing tires and wheels for it. stock size. any ideas?
proline makes a set for the buggy but they screw up my handling cause of too much bottoming out.

with the AON motor go up on the gearing. I think I have 16T now.

[X-MAXX]

Hey duster360 I just bought a this same truck for my son but with a better looking body. the servo can be replaced with same but not upgraded, if servo is changed out and the esc must be upgraded. search integy.com for inferno upgrades. my son is 3 yrs old and it is not to fast for him but not to slow and if some thing breaks they sell it all in your color choice of aluminum. it takes 6 double A batteries and runs for about 30-40 mins depending on how hard its ran. if considering buying one purchase a couple of rechargeable packs or buy stock in energizer batteries. over all it is a great truck for my son, and its a nice switch for me sience my x-maxx is still on the table it'll be finished soon check preivious posts on sat night i'll post pics of inferno too. got the exhaust for my x-maxx cant wait to fire it up. thanks rcboyz came though for me.

X-MAXX

[StevePond]

X-Maxx, you might want to try the rechargable 8-cell pack to get a little more speed (if you want it) out of the truck. The Alkaline batteries simply can't deliver enough juice to get thet truck up to its full potential speed. It'll run about 10-12 mph with the alkaline batteries, but it jumps up to about 18 mph with the rechargable pack.

[auto2]

I have a 8 cell pack tha i would sell you cause i am using lipos now. it is basically new.

[Duster_360]

X-MAXX - thanks for letting me know that, was as I expected. I have gotten too spoiled with a brushless setup and their 30+mph speeds to gut and rebuild another - its like buying one twice and after doing it 3 times, I'm not going to do it again, just too expensive.

If I see an good used one somewhere, I might go that way cause I really like the looks of this one.

Lookingforward to seeing your pics.

[X-MAXX]

anyone seen

[StevePond]

Seen what?

[Mugen man]

sorry no pic will upload now

hey does any one know if the proline mini inferno boddy will fit on a mini inferno st, to make it look like a buggy and not a truggy

[a1hardwoodman]

metal geared sealed diff. sets on ebay check it out.
