Tamiya 1/8-scale TNX Monster Truck

[StevePond]

Tamiya's Terra Crusher follow-up is called the TNX, and lops nearly 4 pounds off the original truck (3.5-4lbs, depending on who you ask). Much of the weight savings comes from the smaller-diameter, thinner-carcass tires--and we all know how all-important rotating weight is. Other major changes include an O.S.-built .18 engine, and a new chassis that spans from shock tower to shock tower (as you'll recall, the Terra Crusher's chassis plate stopped short of the front suspension, where a plastic nose section with integrated electronics box took over). Electric starting returns, but reverse dos not--expect a separate reverse kit to be made available as an option.

- FS-18RS engine
- Pre-painted Body
- 3.5lbs. lighter than the Terra Crusher
- Claimed speed in excess of 40mph
- Electric start
- Two-speed forward only transmission

Wow :D

[Nosaj-Maxx]

That is impressive!!!

How about the Monster GT pics now????:D

[offroadcrazy01]

Those guys dont give up, looks like they will keep trying till they get it right(hoep they do this time)

Wow :D

So that makes it what like 15...16..17 lbs? :confused: :D

It looks good; defiently a good thing that they lost the huge tires.

[offroadcrazy01]

hmmmm, funny how i missed that $734 price tag first time round.

[Terra Crusher]

i think tower hobbies has the tnx listed at 459.00?(US dollars):cool:

[SixVi6-Camaro]

So that makes it what like 15...16..17 lbs?

Actually the TC's lighter than a savage. Taking 3 lbs off a crusher would make the TNX stock T-maxx weight. It will help get that truck moving a lot better.

[unknown person]

wow nice mt but i dont like the body very much, oh well looks like a proline job:D

So then, Could this be the end of the terra crusher:eek: or will the two trucks be brothers:p

[Racer Rob]

Hey Look! Its how they should have done the truck to begin with! :rolleyes:

[rodmanrc]

can you say. PLASTIC.

[muswagon]

Rodman, there is more plastic on the T-Maxx than this thing. Geez guys.

[rodmanrc]

sorry muswgon do you have t max parts i can borrow for mY new TNX thay might fit......this could be fun.........

[Shawn_S]

a .18 in a 1/8??? Am I seeing this right or am I going blind?

That just isn't clicking... :confused: :rolleyes: ;) :mad:

[rodmanrc]

AAAA here we go . any small block motor in a truck that heavy will suffer overheating ,and that stands for TMAX wutsthepoint??????

[muswagon]

Rodman, huh? If you are going to insult me, at least make sense you half wit.

[Shawn_S]

I wasn't trying to start anything.

Just that, I'm used to cars that aren't Underpowered ;)

[Doctor Doug]

I took a few pics of this truck too. They don't look as pretty as the ones RCCA took, but here is the link if you are interested:

[muswagon]

I love this truck, as I raced my old Terra Crusher and did very well, no reason this will not do even better. One thing though, why does Tamiya not want us changing shock positions? My only beef with my old TC was how high it was, I dont want to use fuel tubing in the shocks to get my ride height.

[jdm3849]

Its looking good! But I wish they would put a real header on these things.:(

[metalry101]

Damn, it looks really good, and I really like the body, tires, and wheels. There is a lot of plastic on it, but my E-Maxx has a lot of plastic and it seems to hold up alright. However, maybe it's just me but those shocks look like they're friction dampened. I'm sure they're not, but they look like it with those springs on them. That engine doesn't look too impressive either, but hey, I'll give it a chance, if it moves the truck as well as they're saying it will, then you won't see it anyways. Well, I guess I should qualify that, I like the engine head, it looks strikingly similar to the one on the 2.5, but then again, I like the way that looks so no complaints there. Hopefully this truck performs as well as it looks, if so maybe Tamiya will finally sell some nitro MTs. Everyone loves the TXT-1, but the Terra Crusher just couldn't stand up to the competetion.

[muswagon]

Where do you see more plastic than on a stock T-maxx for example? The engine is an OS.18, very similar to the one on the duratrax evader, but with a slide carb and who knows what inside. The TC was underpowered, no doubt. Other than that however, it was a dynamite truck. With a set of Maxx Mulchers and the baffle taken out it did very well at my track last summer.

[fastharry]

it looks like exactly what it is....a stop gap truck till they come out with a 21 powered fresh design...

[metalry101]

Why does everyone think that a monster truck has to have big block power to be any good? The fastest truck on the market right now runs a small block, and it's also the best accelerating too. Not a doubt in my mind that the .21 Maxxes are faster, same w/ the .26 Savages and he RCX Edition Mad Forces, but stock, the T-Maxx blows everything in it's class away except possibly the Mad Force, but it's got a 3 speed, it should be able to kick the Maxx's ass instead of only keeping up. Anyways, if this is indeed a very similar engine to what's in the Evader then that could be good, although I'm not sure, because obviously that truck has a lot of get-up-and-go, but it doesn't exactly weigh anything compared to the TNX. I guess it all depends on the gearing.

[Popop]

> but stock, the T-Maxx blows everything in it's class
Please do not include in this class the EK-4 !!!!

Note a wider ride always mean a less agile one ... Do not compare a 300mm wheelbase with a 20% longer ride !
If speed is only concerned, prefer a Monster Pirate 10 to the T-maxx !!!

(Sorry it was so easy!)

[challenger440-6]

does anyone know the dimensions on this thing or how it measures up to as t maxx?

[Nitro~Freek!!!]

Anyone Actually own or run one of these?

I was wondering how big it is compared to the savage and t-maxx?

N~F

[cbr74]

It's a Terra Crusher size chassis with Maxx size tires.

[tripplefatty]

this truck will run with alot of the trucks on the market now....big or small block...it dont matter....this truck is just as light as the maxx..truck.....i ran the tc with a 24.7 in it & it was very very fast ...& never tripped a gear....the tranny loved it ....& the new tranny is all new ...the gears in the tc are as just as thick as the sm gears that you maxx clowns pay $ 100 of dollars for...every thing on this truck is inner locking...put to gether very well....i can see this truck doing very well....it was built more for the racer basher in mind...& the motor was built by o.s...& they make great motors...i think this truck will rock..
jamie....

[twisted]

i like the overall designe, hmmm.

[Freedom]

I am getting either a TNX or a Revo for my next nitro model, which ever is cheaper of the two. The only reason the Revo won at the Maxx Challenge is because the TNX's ran out of fuel with only a few turns left before the finish line lol. Steve and his little Revo got lucky.

[madmudder]

I just bought this truck yesterday. It is a very impressive truck. I got 5 tanks of fuel though it now and it gets better every tank.

[Breakin2]

I'm looking at this truck, but it doesn't seem to have that big of a following yet...

[twisted]

yet is the key word. the truck rocks and when more people see how well it is put together they will come over tothe FAST side. lol

[treble2]

got one of these trucks a few days ago. two words "IT RIPS!" ive done 6 or 7 tanks and it gets faster every time.

just wondering... does anyone know if u can put Terra Crusher parts on it?!

[jh99]

Does anyone know if a big block engine will bolt into this truck or does a custom motor mount have to be made? And would the new Sirio .23 maybe fit into this truck?

[StevePond]

I'm sure there is room for a big block, but I'm certain a new engine mount would be required; same for the .23 engine.

[metalry101]

Well...hopefully I'll be a proud new TNX owner someday. I've gotta sell a bunch of my other stuff and find some money for college, but my next nitro is definately a TNX.

[J_Maxx]

New Era Model makes a engine mounts for the Sirio .23 for the REVO maybe they will make one for the TNX :rolleyes: :D

[KevinxB]

I think I might get a TNX. Seems like it has the fewest bugs of all the MTs I've been looking at.

[ps000000]

Does it equal to tamiya 1/10 wheel hub size ( I do my project)

Thankyou

Patrick

[J_Maxx]

New Era has made a .21 - .28 engine conversion kit for the TNX. :cool:
Also could any one tell why I would want to get this truck over the REVO :confused:

[vetmxer]

the TNX is bigger and from my experience with tamiya its probly almost indestructable. the revo does have reverse though

[tnxfan]

i agree with vetmxer. also, i have not heard any complats about the engien

[hyperstang]

I have seen this truck in action at our local off road track. 3 racers have it out on the track right now, and beleive it or not, it beat the REVO and the Monster GT. Well the REVO was falling apart, bronken A arm and the shock came loose from the rocker. The GT never stood a chance.

We have our off road championship coming up and I will be running with the guys from the LHS. They all are going to run TNX's and I thought I would see what this thing does first....I am IMPRESSED. I may pick one up very....very...soon...

Race on...

[JAnderson]

It won 1st and 2nd at the monster madness II race over the REVO

you can visit www.terracrusher.net for more info

[Duster_360]

I ordered mine from Tower yesterday - $20 off due to order over $150 (deal ends end of Aug) and I am a club member so the $23.50 standard shipping was free, so delivered it was $360. What a great deal!! I have 2 Tmaxxes - a 2.5, mostly stock and a TRX race chassis based, RPM parts FR18 which definitely rocks. This will be a nice change, I took the time to read all I could about it - terracrusher.net has a lot of infor and owner experiences on their site - has a whole section devoted to the TNX. They don't seem to be breaking and the motor apparently rips! Can't wait for that Brown truck!!!

[andrew23mj]

I was wonering along with Nitro Freek if anyone here owns and/or drives one regularly. I am very interested in buying one of these. I tlked to the owner of my LHS the other day and he said this is the only truck that he would even consider buying. I know this is only one guy's opinion (s very strong one at that) but I want to k now what you guys find particularly good and bad about the TNX.

Thanks in advance
Andrew

[trw]

hello fellow TNX owners, For Xmas I will be receiving a TNX, and was wondering if i should cut holes in the body to cool the engine head off? or will it run fine without cooling holes in the body?

[Razoo]

I cut holes in mine, as far as I'm concerned I think its a good idea for any nitro truck. Take your time breaking it in and do it exactly how they tell you to in the instructions and you won't have any problems. The stock shocks(plastic) are OK but most people replace them with aluminum ones. I use traxxas big bores. Have fun, its a great truck!

[JamminJay]

well, right now I have the stock shocks with Trinity dual rate springs, but will soon be buying the MGT shocks. I heard those work good on this truck. As someone said on TerraCrusher.net... If they're good enough for a 12lbs. truck they gotta be good on a 9lbs. truck. Also heard the power strokes were awesome, but a lil pricey for me right now. Right now, i'm concentrating on some white velocity dish wheels and some new bowties, if any of you have some for grabs, please let me know. Guess i will be the first to post a pic in this thread..... So, on that note, here's my TNX.

[performula]

I wish this truck would take off because Tamiya is a great product, but the other trucks look as if they will outlast it. RC Car Action had nothing but good things to say about the TNX. I would like to buy one now that the price is cheap for Christmas at Ultimate, however Tamiya might disregard it soon similar to the Terra Crusher.

[KYBOWTIE]

I received a TNX early for Christmas over a week ago. I installed PL powerstroke shocks, had to slightly dremel each arm and that was it. I also installed a pullstart from a CV-RX. I raced it Thursday night and it's the fastest I've ever driven. I led an A-main for the first time, this trucks drives really nice and manuvers very well. I broke it in with 6 tanks and took it to the track, I ran one practice tank at the track and it temped at 206. Never touched the needles all night. I took a few tumbles as well and only bent a turnbuckle and snapped the front bumper which I already had plans to remove it. I thought long and hard between the TNX and the Revo, I made the best choice for me with racing. There are well designed upgrades in the works for the TNX also. ;)

[performula]

Does anyone manufacture extended arms, chassis, and such? I have checked a few site, but they carry Terra Crusher stuff. No mention of TNX.

[KYBOWTIE]

I cannot say who the manufacture is, but can tell you all that stuff is in the works and due out hopefully in a month. It's original products to boot, no knockoff junk. The TNX is an awesome truck with just the PL shock upgrade, I ran stock servos and contoller too.

[JamminJay]

Does anyone manufacture extended arms, chassis, and such? I have checked a few site, but they carry Terra Crusher stuff. No mention of TNX.


New Era does make an extended chassis for the .21 conversion, It is on my truck and it has been custom moded to still run the .18, but it has been moved forward to move the weight forward. New Era does carry alot for the TNX.

[KYBOWTIE]

Here's a pic of mine after mounting a wing and painting a new CP2 lid. Not sure if I like the new CP2.

[turbopower]

Kybowtie- can you post a picture of your rear wing mount. What wing mount did you use. I was thinking of putting a wing on my tnx also. Thanks

[JamminJay]

from the angle it kinda looks like a X5 wing so it may be an X5 mount as well...

KyBowtie- are you running stock shocks and springs or what do you have?

[KYBOWTIE]

It's a hack-job but I wasn't after looks with the wing-stay plate. I used a single piece of 1/16th stainless and cut it with just a dremel. The wing and stay are MBX4 which I already had from my Dace Predator. Ya know, it might be a MBX5, I'm no expert on wings and I ordered 2 of them back in the spring. The shocks are PL Powerstrokes and they perform flawless. Gives the TNX a lower stance for racing. I installed 4mm limiters to each of the sprung shocks.

[aztnx]

I like that wing does anyone know or have a page on how to make a
little lexan wing like the one on the Tamiya TNX's that got second place on the monster truck race?

[turbopower]

Kybowtie- Thanks for the pics. Just out of curiosity did you notice a difference in the handling or jumping balance with the wing. I have a buggy and when you lose a wing on a buggy you can tell big time as the car gets harder to drive.

[KYBOWTIE]

I actually haven't run the TNX with the wing yet. I ran a Dace Predator all last season with the same wing though and they do perform. They help keep the truck straight at speed and when jumping, the truck flys perfect. They protect the lid from getting beat up when you land on the lid and they also give the turn marshalls something to grab ahold of. Wings serve alot of purposes.

[aztnx]

this truck is awsome i have on Stable claws and PL mulchers i have a set of
Big bores for it but i think they need a rebuild, does anyone know what kind
of O rings replacement the traxxas big bores use? i have a week with the truck and havent even fired it yet.

[KYBOWTIE]

Here (http://www.traxxas.com/products/nitro/tmaxx/blueprints/040609%20T-Maxx25%20Parts%20list.pdf) is a link that might help you aztnx.

[aztnx]

Is this the kit i need to rebuild them ?

[madmudder]

I bought a set of dynamite alum shocks for my wife's TNX. I got them very cheap. Well I filled them with 50 weight oil but them still seem to soft. Do they make different pistons for these shocks or do I have to up the oil weight?

[KYBOWTIE]

What is happening to lead you to the conclusion they are too soft? I run 30wt in the PL's.

[madmudder]

Well we haven't had it out yet with these shocks on, but feels too bouncy. Right now if you hold it up about a foot high and drop the truck it bottoms out.

[KYBOWTIE]

Might be a combo of springs and oil weight, I'm unfamiliar with the Dynamite shocks. I drop mine from about 18" and get the axles level.

[turbopower]

Anyone know if OS will come with a TZ that will straight bolt into the TNX?

[KYBOWTIE]

Turbopower, EB Mods might be sending me a TZ to test when upgradable axles become available. Here is my take on what's available so far. I have ran a CV-RX .18 for a good part of last summer in my Dace Predator. The stock motor in the TNX makes great power IMO. I run a duratrax header and RD Logics Tmaxx pipe with the coupler at full length. My suggestion would be to buy a CV-RX .18 or the stock TNX engine and send it to EB Mods to be modified. You would be amazed and what Ed is able to get out of the motor. You would prolly wind up spending less money going the CV-RX + Mod and have more usable power. Go to ebmods.com (http://www.ebmods.com) and then give him a ring. He will gladly take the time to talk to you about what he has to offer. Tell him Jim (KYBOWTIE) referred ya.

[JamminJay]

Ok, well things have come up and I am selling my TNX, you seen the pics above, but heres a little about it has the New Era .21 conversion on it, with the .18 moved forward for better weight transfer, O'donnell head, about 3/4 gallon on the motor in it. Tmaxx tank, removed rear bumper for weight, kyosho buggy springs (4 shock set up) shoock sox, sportmaxx wheels, and bowties, lots of life left in them. Ton of extra parts, arms, shocks, bumpers and skids, bulkheads, springs, drive train axle parts, extra head, diff parts, stock chassis, 2 starting systems (one wand is broke, but it still works)
and another engine that was give to me (it's apart) I was told it needs a rebuild, but the piston is still in the sleeve and it feels good to me. but I am not sure. Theres almost enough here to build another truck. I'm going to put this on ebay soon.... but i will ask less and give someone here a deal. you saw the pics of the truck above, now heres the extras, pics suck but you get the idea. $450 + shipping... thats barely $100 more than what a new one costs.

JamminJay1722@aol.com

[JamminJay]

pics of the parts wont load so email me for them..... wont sperate either. Sorry.

[kurrz]

hey i know the tnx is mostly just a racer but does anyone make a reverse kit for it thanks

[KYBOWTIE]

A reverse kit is supposed to be available soon from what I have read.

[trw]

bout time they start coming out with some mods for it.

about the upgradeable axles eeerrrr soon to come upgradeable axles, do you know an estimate of how much those would run? cause i know on towers theres a duratrax replacement that runs like $100 for all the peices and thats way to expensive where i could just spare plastic ones for $5 a peice.

and this reverse. exactly where would the reverse module (assuming there would be one) go? theres no room for it except between the tranny fuel tank and throttle servo but it would have to be very small.

[KYBOWTIE]

No idea on the estimate, but any upgradable, good quality axles that I have purchased in the past for other models have been 100 bucks or more. If you ae not racing professionally, the 5 dollar stockers are prolly the best route. I personally like the assurance that they won't fail in an important race, so I would pay that amount.
As far as the Reverse Mod for the tranny, all I know is what I have read. Nothing more, nothing less. ;)

im planning to get the tnx too but im thinkin of putting a big block on it and i saw this on new era whats the difference between this and the new 21conversion kit?it says on this i tem i posted that u can also put a bigger engine on that chassis and i dont want to spend another 150s for the conv kit..is there something u need to do on this chassis that u dont need to do in the conversion kit?

[trw]

a bigblock conversion would be a waste of money, this truck was built to run with smallblocks and ride the bumpers of trucks with bigblocks, actually it passes most trucks with bigblocks lol, instead you probably should consider a high end smallblock like an OS 18 CVR or TZ, or something along those lines.

[badboy2]

will the picco for maxx fit?or the sirio23?

[KYBOWTIE]

I sent a CV-RX .18 to EB Mods to run on my TNX. If you want BB horsepower, install the OS .18TZ. It has 2.28 horsepower.

Thanks

[kurrz]

is this truck as tough as the mgt and savage in your opinion im looking at all three and cant decide i am mostly going to bash but may race in the future thanks

[badboy2]

i never had one but i used to have a terracrusher which was the predecessor of the tnx and it was tough ..but if u want this type of set up id go with mgt theyre almost similar and also tough and can be raceable too ...savage is the all time basher

[kurrz]

thanks i dont know why but i just cant make up my mind i have experience with tamiya and havent had a product from the others also the tnx seems to be the racer of the bunch but i suppose i could wait til i decide to race then get a tnx thanks

[badboy2]

if i were u id get mgt ...i sold my terracrusher cuz i wanted the big block which is also the same thing thats holding me up to buy tnx but i like tamiya also....mgt is definitely a nice racer and 2nd toughest to savage ..

[kurrz]

yeah i think i will thanks

[Monsterbrad]

this truck just does not have the popularity
sorry tnx guys :D

[TC3Racer]

Can anyone here compare the TNX to the Revo? Those who have experience with both? The Revo seems to have incredible handing and seems really set for racing but i just love the TNX. I know that it was beating Revo's in some of the big races but i want to know what you guys think who race against Revo's or possibly those who have converted or own both. Thanks alot.

[mr-e-maxx]

I own both TNX & Revo they are both very capable racers,however the TNX
out of the box will cost you a lot less money to get it into racing forum and if you want to go big block there is plenty of room on the chassis to do that ( although even with the small block the power to wieght ratio is awesome no need to go BB) The Revo on the other hand you will want to go BB right away because the Tnx out of the box will beat the Revo.
The Revo on the other hand will cost you more to get into racing forum and also the Revo will cost you more to keep up. The Tnx is a very tough truck right out of the box, if you don't race, the Tnx is one of the toughest trucks you can buy out of the box which makes it a great basher also. So there you have it the choice is yours. :cool:

[TC3Racer]

Awesome - thats exactly what i wanted to hear :D . I was pretty much wondering how they matched in RTR form and you answered that for me. I really like the TNX and how capable it is. The power to weight ratio is one of its biggest assets and it doesn't take much to get it to be very racey.

[dag32]

What race class is the TNX in? Does it race with Savage, Revo...etc. or Truggies

[badboy2]

in my track they race them with the maxx savage mgts and the truggies

[amit1]

the tnx is 1/8 but why he is so small

[crusher3379]

its not small, its longer than a savage and a hair wider.
Id compare it to the lst and mgt

is it work the hassle to get a used terra crusher and convert to tnx?

what parts are needed to do it?

[crusher3379]

no, i have 4 tc and there ok for bashing, but you need diff, chassis, tranny radio, etc.. just get a tnx, you will be happy with it. also made of a lighter plastic than the tc.

As far as savage 25 vs tnx, tnx is a racer, it can bash with the savage but the savage is a tank, it took a wot run into a telephone poll to break it. my tnx on the other hand as had nothing but track time on it and so far its asnt done any damage. love this truck

The one way bearing in the starter slipped more then not, the transmission would not shift right and after sending it back to Tamiya 3 times I sold it at a big lose! They sure did not make the Terra Crusher very long. Is the TNX better then the Terra Crusher?

[turbopower]

One word - YES

The TNX is lighter and has quite a bit more power. Read all the posts on the TNX, I have never heard anyone say they regreted getting the TNX. In fact most people that have multiple trucks always like the TNX better. I have a MGT, TMAXX , and TNX. If I had to keep one it would be the TNX.

Have you ever owned a savage? Do you bash or race?

[turbopower]

No I do not own a Savage, cause I drove my friends savage and it doesn't handle very good. It is one of the best jumpers as it tends to center itself in the air and has a super plush suspension. I bash and run my vehicles on tracks. My criteria is handling and durability number 1. With speed and acceleration 2nd.

The Terra Crusher and TNX are based off the same platform but they are two totaly different truck when it comes to driving them.

So you agree the Terra Crusher was junk and I am sure the TNX is a good truck just not for me. Did you ever own a Terra Crusher I did and know it was junk. I just bash and if I raced I might look at something else. As far as handling there are things you can do to in prove it. Even on HPI web site they say they designed it for bashing and jumping not racing. One thing I do not understand about Tamiya is why they run the poor exhaust header, long out dated where the gases have to make an abrupt 90-degree turn. I all so do not under stand why Tamiya, Traxxas and some others do not have ABC sleeves in the engines like the entire top engine and high-grade RC manufactures do. Bottom line there is more then one good truck on the marked and all are made for different types of running.

[turbopower]

Yes I agree the savage is a good truck. Very durable except the diffs. One of the best bashers on the market. The biggest downfall is the highcenter of gravity and super plush suspention for any type of track duty. So when people ask what truck to buy and they want to run on a track the Savage should not be recommended as the best.

I understand you sour taste left in your mouth about Tamiya products but you have to drive a TNX to understand why it is liked by so many people that have multiple trucks. As for the header and engine complaints, you have to see one run first in person as this is a very quick and fast truck. It is one of the fastest monster trucks(not truggy) on the market right now.

I guess you do not know about the new up grade that comes in the new .25 Savage RTR and the 4.6 where they now have 4 gear differentials and do not have problems with them any more. All so according to Tamiya web site the TNX goes about 60 KLPH witch is only about 37 miles per hour, which is not fast in this day and age. A Savage .25 will run that fast if not faster and we will not talk about the 4.6. As we all know you take what the manufactures say with a grain of salt just like claimed HP.

Bottom line run what makes you happy!

[turbopower]

46u- I hear you. Drive what makes you happy. But the numbers tamiya gives you are very conservative.

[arne]

Sold the savage for tnx .Best ever decision I ever made.So happy I bought the tnx . The savage couldn t touch the tnx in speed never. Thats said. Ever aspekt of the tnx i love

I am happy for you. :D

[trw]

whao lol, talk about perfect debate for me to get into.

both me and my friend got into nitro MTs not to long ago and i bought the TNX and he bought the savage 25, lets just say hes selling his for a TNX now :D

the issue was, the savage could not handle more power then the stock engine, he slapped in a picco 26 and stripped every spur he tried, until he bought the RR set ofcourse, and yes, we had 2 LHSs look at his truck and it stripped even after they worked on it, athough once he bought the RR set it never happened again but i feared for his tranny after that.

and even with his picco 26, i could still outrun his truck with an OS 18 CVRX in my TNX, oh yea which btw is just an updated version of the stock engine which comes in the TNX out of box, basic differences are ABC sleeve, machined head, and different visual treatment, in short, the TNX is a sleeper, dont judge a book by its cover :)

although i am not gonna deny it but the savage could jump really well, but was a huge PITA to work on.

however i understand HPI has done more R&R for the 4.6, and i look forward to seeing how one of those run.

I disagree with you in saying the TC is junk. You have to be patient with it and learn it's weaknesses. You can upgrade some part in order to be competitive. You are right about the bearing and the starter but you can replace the whole thing with a new engine like OS.18 cvrx, problem solved. Once you've learn how the transmission work (FRAT) you will know how to fix it. Never got a problem with it after I learned and change the part you have mentioned. The TNX and TC is almost the same platform and durability. Here's the picture of my Crusher with Buster as his friend. You will notice the body is a bit smashed after serious beatings.

[TC4]

Here's another shot.

[trw]

hey i got a question for you other TNX owners out there:

im probably going to drop a TZ into my TNX soon, and was wondering if anyone knew the steps to get it to drop in, i realize its a rotary carb, could i use a slide valve carb off an 18 CVR?

also what header do most of you with the TZ in your TNX use?

[fasenough]

I used a HPI RS4 header but I also had Proline shocks so it had just enough clearance. I also used the TZ-TX model with the pull start and rotary carb. I got the rotary carb to work by extending the fuel linkage out on the servo and bending it about 30 deg to get it to pull the carb down straight. I also turned the carb counter clockwise as much as possible without it getting any interference from the head. So far I have been using stock gearing and stock clutch and it has worked really great. It was very nice out of the corners before but now it will pull willies out of the corners. I am very happy with it.

I have a terra crusher with mostly TNX parts on it (bulkhead, diff case, up & low arms, bumper, skid plate and steering). The only left from the original is the radio box, center diff and chassis plate. I can tell you it's as durable as HPI's savage whose rep is "the most durable truck". It can handle:

BIG jumps (not big big - you'll gonna break parts if you do this),
staircase??? It can go down but I don't think there's a nitro MT the can crawl a staircase (for nitro crawling buy the XTM Factor or something),
skateboard ramps??? Can do.
Top speed??? No question one of the fastest for stock.
Torque??? Tuned right, it can accelerate so fast. Tighten the spur and it will wheelie on command.

The way I see it, with the PRO version let alone the Concept version will be enough. No need for "bling effect" unless you chose that your truck will be on display only.

Very Durable, skateboard ramps parks, motor cycle ramps, Full-size monster truck ramps--- Mine has seen them all!

Torque is insane! Motor built in cooperation with OS

Top Speed is 40+ mph

Wheelies are easy with this truck!

I was wondering how easy it is to clean and maintain the TNX. I currently have a Revo and it is pretty tough and I was thinking about getting rid of the Revo for a TNX.

The TNX is laid out and the spacing between each components is nice. You can clean it easily. Revo is crowded and all the components are closely knit together.

I am interested in getting into nitro MT racing as that is the primarly class out here. I see that ultimate hobbies has the original RTR TNXs for under $300 with free shipping. How much better is the Pro version versus the original RTR TNX?

Also, how would you compare the TNX to say the Losi LST?

TNX pro = Light but with small engine (yet so powerful)

LST= Fat, big but with big block engine (but most of the time craps)
& top notch radio system.

Durability out of the box: TNX (no mods needed)

Design presentation: LST (All RTR should look like this)

Speed = LST

Money needed for repairs & maintenance = LST (needs more money to maintain)

Novelty car = LST (it's like a candy to a little boy)

Amount of Fun = TNX (less bench time more run time)

Amount of Hop ups = LST

Nitro consumption = LST (big block burns more fuel)

Engine & parts reliability = TNX hands down

[Cain]

thanks for the info. What are the stock servos rated at? What are the popular servos you guys have been replacing the stock units with?

[patrick scot]

i have a tnx pro that i race. i installed an airtronics 94358z it's 94.99 and has a .10 speed 200 torque. if you plan to race i would buy the tnx pro. it comes with the proline shocks, proline tires, which are definate upgrades the tnx needs. i also installed A mgt fuel tank(no primer and still runs if you flip it over) i also installed tmaxx turnbuckles and rod ends. the tamiya ends will pop off on ocassion. the engine in the tnx is incredible. the low end power is excellent. i had a revo and sold it once i bought the tnx. my lst is on the way. i had to have a big block. i know alot of people with lst's. if i only could have one it would be the tnx pro. i bought a ton of parts on ebay(hard to find shops that carry tnx parts). the only parts i replaced so far was tie rod ends and one spur gear. i never broke anything else. i've seen in other forums that the axles are bad, however i never had a problem and my friend broke one axle. i don't understand why more people don't own tnx's. hope this helps the stock servo is plastic and rated at 90 torque at 4.8 volt probably 110 torque 6 volt.

would the tnx pro be a good investment then

[madmike]

airteballz, Did you have to move the servo up to put the MGT tank on?

[patrick scot]

airteballz, Did you have to move the servo up to put the MGT tank on?
yes you have to drill new holes and move the servo up. i also did the mgt tank conversion. pat

[Mongoose420]

has anyone tried any other tanks than the mgt tank? Tmaxx tank with 6~8" of extra tubing and maby a extra fuel filter, or a savage 21 tank?

will a t maxx bell fit on the tnx...if so what would you need to do to make this happen
thanks

[kurrz]

I have narrowed it down and think I will be purchasing a TNX soon. I will not be racing just bashing. Does the truck have good ground clearance and is it tough? Also anything I should order for spares? Are the plastic outdrives a problem? Also should I go pro? And is there any way to get more ground clearance? Thanks

To be honest, ground clearance isn't very impressive with this truck when compared to other monsters. It's not like a buggy or something, dragging its belly over everything, but it's not as high as an MGT, or a Revo, or anything like that. At full ride height, it's up there, but most people don't run their rigs at full ride height...so...

As for the durability thing, yes, it's very, very durable. The only thing you might want to get spares of are spur gears. I've heard they're a problem, but I've only stripped one. When I replaced it I locked the slipper down and wedged the engine over as much as I could (fixed mounting position), and I haven't had a problem since, which has probably been close to half a gallon of HARD running.

Whether or not the Pro edition is worth it depends on how you plan to use the truck. For hardcore bashing, I say yes. The stock shocks probably wouldn't handle the kind of air my truck sees on a regular basis, whereas the Powerstrokes soak up 10-15 foot landings without a sweat. The engine head is nice, and probably helps keep temps down, but I doubt it's that important. The extra wheels and tires are just a personal preference thing. The stock shocks aren't bad, but think Maxx or MGT factory shocks. They're smooth and plenty functional for average usage, but for big air and hardcore abuse, you'll start blowing the caps off and whatnot. That's the biggest thing, are the shocks worth it to you? That's going to depend on how you drive more than anything.

I haven't had a single problem with anything in the drivetrain other than the one stripped spur. It seems to be pretty strong to me.

There are only two ways to increase ground clearance. Increase ride height by adjusting the shocks, or put taller tires on it.

[kurrz]

Can an increase in the ride height be achieved with the power strokes? And what type of ground clearance will that give? I'm looking for around 3 inches. I plan on bashing pretty hard so I want/ need a decent shock set up and I know power strokes are around what the additional cost of the pro is, and the extra tires and rims and the head are just bonus. Also I run in a gravel pit alot will the bow ties work well in this environment? Sorry for all the questions, this will be my last large purchase for awhile and I want to make the right choice. Also any needed mods?IE: steering servo or cvds?

I dunno about the 3" ground clearance thing at the skids. That means max ride height on any truck, which means super-****** handling and all of that. You crank down the Powerstrokes and get the ride height up, but I wouldn't really jack it way up, but you could.

I don't know if the Bow-ties work in gravel or not to be honest, I've never used them on gravel. The truck does still come with the stock tires too...they might be a better choice for all around bashing. I prefer the Bow-ties for the dirt I drive on.

I'll work on measuring ground clearance and such for you later tonight. Right now I want to use the couple of daylight hours left to rally my trucks (including my TNX) around.

Does anyone know why the Pro version has been discontinued?

[ministerOFfire]

Does anyone know why the Pro version has been discontinued?

I guess it was a limited edition? Or mabey Tamiya is coming out with something entirely new?....

[crusher3379]

proline only gave them so many powerstroke shocks and tire sets to use. once they ran out it was simple discontinued

[Combatcm]

I'm in the market for one. I'm glad that was the case for them being discontinued. I thought they were phasing it out. The worst thing for a truck is it's parts slowly being discontinued.

Do they powerstroke shocks give it a real edge on the track?

How do you make it one speed to race, do you just crank down a two speed adjuster screw?

[crafty1]

Been out of R/C for about 15 years, so much agonizing over what to get as my first nitro vehicle. The light weight of the truck and reviews like "I owned a MGT, Savage and TNX...I sold the others and kept the TNX" finally convinced me! (ultimatehobbies.com having a killer price and free shipping also helped!)

Anyway, what do I need to accumulate while waiting for it to arrive. (Not talking about basics like fuel, batteries, etc.)

1) Failsafe? Is the basic Duratrax one OK?

2) Glow plugs? What do people use? Are the Tower Hobbies brand ones OK? Or is one of the OS brand ones better?

3) Shocks/Springs? From reading forums it seems like the original ones are pretty well disliked. Are there any budget upgrades for a "basher"...like the stock MGT, Maxx or Warhead sets that go cheap on EBay?

Anything else out there as must do initial improvements? Any key hints or lessons learned for a first time nitro user?

- Mike

[crafty1]

One more...

4) Pull Start? Is it worthwhile to ditch the extra weight and complexity of the electric start set-up? Is there a pull-start brand/part# that bolts up to the TNX engine?

[Pat Fierle]

proline only gave them so many powerstroke shocks and tire sets to use. once they ran out it was simple discontinued

R u sure?cause the powerstrokes themselves are discontinued so it seems like pro-line just doesnt make the shocks anymore. thats just wat i think though.

[hotrodda]

What temperature does your TNX run at when tuned for performance? I'm breaking in my new one (with pro cooling head) and it seems to run really hot. Previous cars i've owned run around the 220 mark with good performance, but this TNX is around 250 while super rich. If i try to get better performance out of it by leaning slightly the temp skyrockets.
Also, the recommended settings in the DVD are obviously just a guide, 3 turns out on this particular engine almost melted it! I'm running 4 turns out now, and it's still 250. Is this normal?

My TNX runs around 220 with 30% nitro. I have the stock cooling head, each motor will be different because I run 3 turns out most of the time. It has never been above 235.

[hotrodda]

OK, mine has definitely got something wrong with it then. I can run as much as 6 turns out and it seems to have no effect on temp at all, it's always about 250-270 no matter what I do. What things affect running temperature apart from the mixture? I don't seem to have any air leaks, the needle assembly in the carb is ok,(I thought it might be blocked and causing a lean condition). Does the type of plug affect temperature? I can try a colder one. I'm really running out of ideas with this thing. Is it possible it wasn't shimmed properly at the factory?
P.S. I'm running 25% nitro

[hotrodda]

Don't worry, I've fixed it. The low speed needle was too lean.

[hotrodda]

Has anyone had a problem with the electric start on their TNX? I think i've burnt the motor out! either that or there's too much compression for it to turn the motor over. Can these be converted to pull start?

[MajorHavoc]

Does anybody have instructions (or a link to instructions) for adding the pillow ball suspension and "Pro" shocks to a standard TNX?

Thanks!

[mLst182]

to install the powerstrokes just install them like regular shocks but dremel out a small half moon shaped space where the bottom of the shock connects onto the a arm. that will let them move up and down without binding and will perfom much better. and the pillowball suspension im sure comes with directions. if u look at the stock set up then u should be able to install the pillowball with out too much trouble.

[Duster_360]

Does anybody have instructions (or a link to instructions) for adding the pillow ball suspension and "Pro" shocks to a standard TNX?

Thanks!

Here's the pdf for the pivot ball suspension kit. It was my understanding that once this is installed the powerstrokes are a direct bolt on. Trimming is only required with the stock suspension.

http://www.tamiyausa.com/pdf/manuals/53868ml.pdf

[MajorHavoc]

Thanks for the info. guys!!
The pillow ball suspension install was easy!

The Power Stroke shocks however, have a different size connector top and bottom.
They require metal bushings so the mounting screws will fit. I happened to go to Tamiya in Aliso Viejo, CA today, and they don't even have these bushings in stock!!
They are on backorder from Japan.
The guys there were helpful and did manage to find some parts in their parts bins that should work!
I'll assemble it tomorrow!

Depends on which version you have. I have no idea what crankshaft you need (haven't ripped my engine down that far yet), but you'll need one with a slide carb. It's probably possible to get a rotary carb version to work if you relocate the throttle servo and create a linkage similar to a Pro .15 T-Maxx's, but a slid carb version would be easier. It should work great though...I believe the stock engine is basically an .18 CV-RX....or was based off of it at least.

New Era big bore header, MGT muffler - will kick perfoprmance in the pants (be warned - MGT pipe is LOUD, hehe). Stock shocks are kind of wimpy, The hot ticket was to replace with Powerstrokes, but need either to trim the a-arms to clear or trim 3 fins off shock bodies. Now with the pivot ball upgrade, the Powerstrokes will fit, but you've got to find right size ball ends to adapt and make them fit. Tamiya is supposed to have them, but everybody says never in stock. Get a rechargeable hump pac and tie it forward to help keep the front wheel on the ground. Need better tires, but the series 40s are too big, stay with regular profile.

If you run it hard, can strip spurs due to flex of the plastic ladder supports under chassis. Buy a screw kit and remove the wood screw thingys and replace them with normal, hex head threaded screws. These hold better, don't back out and stiffen the chassis up so much less likely to strip spurs when things would otherwise start flexing.

Duster_360,

THANKS!!! Great info, I am taking notes ;)

I do have brand new Proline step-pins on RPM rims that I was gonna put on my Maxx, I think I am gonna throw em on the TNX when it gets here.
I have a brand new Revo (blue) pipe, I will see of I can swap for a used MGT pipe too.

[mdewitt71]

What bodies fit the TNX really well?

Any pics of you TNX trucks??? POST EM UP!!!

I am thinking of going with a Pleazer 2.0 (MGT size).

[Duster_360]

If I have this right, the pivot balls to make the powerstrokes fit right - you can use P/N HPI 75121. Think those were the ones I used. Tight fitting rubber tubing will work in a pinch. I used a set of alum hot bodies Tmaxx shocks for a while that way - better than stock shocks, but won't touch the powerstokes. Before they started fading in popularity, could find them on ebay for $75 - only $20 more than alum bodied shocks and worth every penny of the diff.

I have Crowd Pleaser 2 also, #3186-00 - label says it fits a TNX - I got a stock spare bod with mine as a freebie, I use one as a beater and the new one as a shelf bod. Never have gotten around to painting the cp2. I've seen several and they fit well and look good.

[mLst182]

i just ordered a crowd pleazer 2.0 for my TNX. heres a pic with the stock body.

Is that the 23mm hub conversion on yours?

I was thinking of getting that too.

[mLst182]

yea they are the 23mm and they work great

http://i3.photobucket.com/albums/y93/combatcm/12mmoneway.jpg

Here is mine, I spend time on tamiyatrucks getting tips for the truck. Mine is really a big mess of performance tweaks I have done and what other people have done.

MGT servo saver
GPM diff cases
Nova diff cups
Powerstroke spring shocks (70wt R 80wt F)
powerstroke hard blue springs
TSAIS nitro devil pipe
OS .18cv
Custom one way front
Lightened stock clutch (drilled holes in clutch)

I showed a picture of the one way. It's a 12mm socket that has channels drilled in for the dogbone. It rides on an HPI 12mm bearing on the front transmission shaft. VERY trick to have for racing.

[mdewitt71]

I got mine yesterday but ended up chewing the spur gear on it's first (since I have owned it) run............now I am waiting on another gear as my LHS does not have one in stock :mad:
Already got some Velocity wheels and bowties coming to slap on it too ;) .

[Duster_360]

Tamiya supposedly upgraded the spur gear, so maybe you'll get the newer one - same p/n so you really can't tell which one you get. Newer one is thicker I think (stillrunning my orig). Since the TNX doesn't have slots in the chassis for adjusting the spur/pinion mesh, its easy to assume it can't get messed up. There's enough play in engine mount holes though that it can.

If any of the screws come loose on the trans, it will strip the spur. If the screws that hold the chassis braces come loose, it will strip the spur. They only have to loosen enough to allow just a small amount of relative movement then the spur eats it. The stock screws are those awful phillips headed wood screws things that routinely come loose. I bought a screw kit that replaced those with hardened steel screws that thread themselves into the plastic and stay tight. They don't come loose. This was the tip that the winning Tamiya drivers Jimmy Jacobson and David Jun passed along when they were on TamiyaTrucks forum.

My advice when you get new spur, play with the mesh by twisting the engine in the play the fixed position allows. Check mesh and find the place where its best. You should have just a tic of play between the pinion and spur - some use paper to set theirs - I used a dollar bill til I developed the feel for the correct mesh. Before running and frequently while running, stop and check the trans and chassis brace screws to keep them tight. That should improve your time on the next spur.

[mdewitt71]

Is the 10mm Spur gear the new one?
I see these two at Tower:

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLUK1&P=7

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGZD7&P=7

[Duster_360]

Since this is non-adjustable (chassis is not slotted), it has to be the 43t spur if yours has the 17t pinion. I think the 44 is an option part for a smaller pinion, also an option part? They would have to be changed together, in the opposite direction to maintain the fit. I'm not real sure about the 44t, but I think I read that it was possible to use 44t spur with 16t pinion??

The toothed part or gear part of the pinion is threaded on the clutch bell, its two separate pieces unlike others where the gear part and CB are one piece.

We were told on the tamiyatrucks forum the p/n was not changed and the new ones would be out there when the older ones were sold out. I think this is the right one - same p/n shown in my manual -

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGYX9&P=M

[mdewitt71]

ooops, I may have ordered the wrong spur at my LHS then, I will get this one thru tower......

What exhaust header from tower will put the exhaust out my rear and give me a lil more umph?

I will make the order together :D

[metalry101]

I'm not real sure about the 44t, but I think I read that it was possible to use 44t spur with 16t pinion??
That's correct. That's the setup my truck has been running for 3 gallons or so. Haven't stripped one yet...it rocks.

[Duster_360]

......

Best I can advise is to PM Combatcm (that's his truck shown above with the rear Tsais exhaust) and ask him what he used. I'm using the big bore header from NEM, with the stock location of the exhaust. May be able to use a compatible side exhaust header and just filp it over. Looking at my NEM header - would be too high flipped over to be useable. Whatever you do, be sure to spend a little time port matching the gasket to the engine and then the header to the gasket. Want all the umph you can get!!

metalry101 - thanks for confirming that, may be an option I want to explore with mine!

You have to buy the Tsais nitro devil TNX pipe.

http://www.tsais.com/products/exhaust/tunedpipes/10/E1021.html

I had the MT2 rear pipe and I used the stock manifold, just put on the opposite way.

You are going to have to buy the tnx pipe kit anyway and it has the manifold in it.

[mdewitt71]

yea, I already emailed them (TSAIS) about the pipe, just gotta get some $$$ from "mamma" for my toy and I will order one.

$50.00, it better be worth it!!!

[mdewitt71]

Here is one for ya, anyone got a TNX original box laying around that they would part with?
I like having the original box's and didnt ask before I bid on this one so I got the truck, manual, and service kit but didnt get a box with it....
Nothing big, just like to have the original boxes for storage and packing when Uncle Sam moves me.....

[metalry101]

I'll have to ask my mom if she threw it out. I had it at my parent's house, but I think it got thrown out last week.

[mLst182]

does anyone know a good pipe that would fit onto the stock header besides a rear pipe like the TSAIS. i want a side pipe. well a pipe for a 1/8 buggy work maybe?

[Duster_360]

The MGT pipe (not the 4.6MGT, the older 21based MGT) does well, but its LOUD (single chamber) and gives you a noticeable power increase. You can get one off Ebay pretty cheap from someone parting one out.

I don't know if the 4.6MGT uses the same pipe as the older version or a diff one.

[metalry101]

Has anyone here tried the THS pipe that's made for the HPI RTR3? It should bolt right up, and looks very simliar to the Tsias side mounted pipe. I'm considering getting one for my rig, and given that every other THS pipe I've seen kick's ass, I would assume this one would too, but if someone here has run the thing, I'd love to hear an actual report of how it works on the TNX.

[mLst182]

Just painted my first body for my TNX . Take a look !

Wow, that CP2 really looks nice, good job! Like the CF scoop on the front.

Dang, I've got to get mine painted seeing how nice yours turned out, lol!!!

[RedDevil210]

Does anybody of you know where I can get the Tamiya TNX for a good price? Because all the shops I know doesn't have it anymore. I know that there will be a new one, but first of all, its to expensive for me and I like the old TNX!
Thanks

[Duster_360]

http://www.ultimatehobbies.com//l129.html

11th one down on list. They say they have them in stock.

[RedDevil210]

Thanks for the tip!
How is the spare parts support of the tnx? Will the new TNX be about same as the old one so I can use most of the parts from the new one for the old TNX?

[Duster_360]

I've not had probs with parts for mine - I get mine from TH, they seem to have it all from the little rubber things in the starter motor drive to the latest in hopups (pivot ball converson).

Can't help on your ques on the new TNX, all I know it will have a bigger motor and prob a better drivetrain. Would be nice if they slotted the chassis so you could adjust gear mesh, but I've not had probs eating spurs, so I gues its not that big of a deal either.

I've got two and I'm wanting to sell one of them. LMK if you want it. $175 and it's yours.

[RedDevil210]

@metalry101 Do you have pictures of the TNX? Tell me something about it, how old in which condition,...? Thanks

[ministerOFfire]

...anyone know of the best online shop (best price) for the new TNX?

[mdewitt71]

The above link that Duster posted is probably the best, unless you get a big coupon from Tower.

[metalry101]

@metalry101 Do you have pictures of the TNX? Tell me something about it, how old in which condition,...? Thanks

It's in good condition. The shocks are brand new...zero tanks on them. I've never driven this TNX so I can't say how the motor is but it has a lot of compression left and seems to have been well taken care of by the previous owner. I dont' have a painted body in good shape to give you, but I've got a brand new, never painted stock body I can include.

The problem with the link above is, that this shop does not ship rc cars to europe! I don't know why but thats life! Sometimes i have the feeling the us think europe is a third world country! *g* Because I don't know what problem it could be to send a rc Car to Austria!

[bebop]

Guys,

Where can I get parts for the TNX Pro? What I mean is Spur and Pinions and brake and clutch? Are they compatible with some of the parts of HPI, Traxxas, Associated ??? My LHS does not have them, where can I get parts online? Tamiya.com ?

Thanks

Thanks

[Duster_360]

Have you tried TH? I get my TNX parts from them, they've had what I've needed so far.

[AreSee]

Hello everyone, I've recently dug up my TNX from the deep dark depths of my closet and dusted her off, I've been out of RC for a few years, mostly because my real Jeep has been squandering all my money :D

Needless to say, the TNX needs work, the tires somehow got horribly off-balance and I quite fancy them, so does anyone know where to get a new set of TNX original wheels besides Ebay? (I'm not a real Ebay fan). It also needs a new engine (or rather, I would like a new engine) what are the good engines of today like? And what is a good engine to use in a TNX that wont eat up the plastic driveshafts?

I also saw the new TNX in the 'hot new products' section and noticed Tamiya FINALLY put a steel spur and dogbones in it, will those be useable on the older TNXs?

thanks for any help :)

[adrenalinrush]

to answer your questions (in order)

tower hobbies
no idea
yes

i have some stock tamiya TNX wheels for mine laying around, but they are filthy, and they still have tires (umm...what used to be tires...) attached (partially) to them

[metalry101]

I've still got stock tires that I'd sell you as well. Under 5 tanks on them.

As for the driveshafts and such...yes...I believe they'll work, but I'm not 100%. The spur gear probably won't. I'd imagine the new truck is geared quite differently since the engine is twice as big.

New engines? I think the most popular swap is the .18 CV-RX from O.S. I believe it's a direct bolt-in. It's probably just about exactly the same engine...but it's cheap and strong so why not go for it?

Actually, the original wheels aren't on towerhobbies, as I checked earlier, hence the question, unless I didn't search well enough, but I didn't see them on the replacement parts list for the TNX.

my TNX currently does have the OS .18 CVRX in it, but I tried to run it earlier and quickly discovered the sleeve must be toast as it idled horribly, I had it set REAL rich, yet it still overheated and generated next to no power, so a new one is on order then, I was delighted to see the price came down to $100 vs when it was $180 or so way back.

also, Metalry, how much would you want for your wheels?

[crate]

hi all,

I'm new to the nitro world(owned electrics for about 10 yrs) and i just placed my order for this truck. I have a few questions that i havn't been able to find on here.

1) what type/brand of fuel do you all run with?

2) I haven't noticed this on this form but others suggest doing a hot cycle breakin(i belive is what its called) compared to the old way of breaking in engines. Do you all agree/disagree?

3) in this message there are links to this www.tamiyatrucks.com website. Everytime i've tried to go to this i get server is down, did a google and had it load via cache settings. the last cache google had was some time in 05. Done anyone know if this site is still active? if not any other tamiya sites around beside the tamiyausa one?

Thanks in advance

[AreSee]

1. O'donnell 30%

2. last that I remember, I used this method.

3. is beyond me

*edit* nevermind about the wheels metalry, I pulled the tires off my rims and I'm just going to replace the foams, mostly because I want to paint my rims black now

[metalry101]

I run Odonnel 30% as well.

I'm not sure about "hot cycle" method...I don't know what that is. I let the truck idle for a tank, cool, quarter throttle (vary it, but no more than 1/4) for a tank, cool, 1/2 throttle, and so and and so forth. Then I start leaning it out.

As for the other website...I don't visit that site much I don't know to be honest.

[Secretsg]

Tamiya Trucks in down for server maintenance. It's been slow lately so maybe the owner (JAnderson from TamiyaUSA) is fixing it.

that would be the heat cycle method if I am not mistaking.

[crate]

Thanks for all the info. sorry about called the heat cycle. hot cycle...

My truck just arrived today , just have another question. here in IL the temps are in the lower 50's upper 40's the next week or so. Should i do anything different in the break in process since the temps outside are low?

[mLst182]

It should be fine with those temps, but in the really cold weather you want to run it a little bit hotter. Atleast thats what Ive found works the best.

[Blazinwarrior78]

my friend has a nitro terra crusher. It has a problem shifting from forward to reverse. I think the shift mechanisism(sp) is not correct. I can't get it to shift at all, how do I adjust the forward/reverse portion of the trans?

[mdewitt71]

My ez start electric motor gave out....wont spin or start the truck.

Should I yank it and go pull start or other means of starting?

Is there that much performance gain if I do and what part #s would i need to do it?

[metalry101]

I don't believe that's an option any more. The one way and pull-start that we used to use have been discontinued, so I'd just find another starter motor and stick with that.
