Traxxas Nitro 4-TEC Forum

[Stickboy]

Are there any sites out there with good setups for Traxxas Nitro 4TECs?

We have a small club in Rochester, NY and most of us have 4TECs ...

Thanks!

Anyone got a 4-Tec nitro?? I want mine to go at least 70 MPH and was wondering about a 38000 rpm .12 or a NovaRossi TX15: 1.35 bhp @ 34,500??? :confused:

Anyone???

PS: Currently does approx 50 MPH (I NEED MORE SPEED :rolleyes:!!!!

[sniper-8]

If anything go with the tx15, it has less rpm but more torq. You want more torq because you are probably going to use a high gear ratio to produce that 70 mph.

With the trxpro 15 you can do 70, put an aluminum tuned pipe on and use a high gear ratio and you will reach 70 or beyond and you will have some money in your pocket from not buying the engine. The pro-15 is almost the same as the nova. you wanna buy. if anything the trx pro 15 has more power. currently you are using a stock pipe and a stock gear ratio right? if yes, get the aluminum pipe and higher gear ratios.

I forgot to add that I use a airtronics M8 radio.

[BigCatDaddy-Outlaw]

SO how well does this beast run? How well did it run stock? How do you like it compared to other nitro tourers? Sorry for so many Qs, thinking about making this my first nitro. :D ;) :)

[krayzie]

it runs great,,in stock form its very fast,and is very fun to drive..You will like it.

[faryns my chick]

please add more things

[USA-1 Nitro]

I have one...love it. Its all stock except duratrax bearings, Trinity touring pipe, and a OS .15 CV, and my own radio and a high torque steering servo. I don't all the fancy stuff...I just use it to fool around with and bash with my other cars and I only replace parts with better ones if they break or if it really needs it(havn't busted anything yet).

[centralparkkiller]

I just bought a brand new nitro 4 tec w/o radio part # 4804 for $190.00

DID i get ripped off? Also what radio system do u guys reccommed for this r/c

[kkd]

Well, I've got one with the stock TRX motor and it screams!!!! I pulled the ez start first day (same as I did with the T maxx.. :rolleyes: ) and then I put on a powerline head for better cooling, pull start and I tossed out all three shims :eek: !!! The piston doesn't hit the top (I checked) and compression is a little high :rolleyes: .... But it is probably over 60 mph now...LOL... Gotta love it...

sees ya..

[AndroidRC12]

I have a four tec not really into hopups I think the car handels great and is really good for someone just geting into nitro like myself I have found it easy nto tune. It screams too. I just got some new tires yester day have not put them on yet but I am soon.
ARC12 :D

[centralparkkiller]

I just found out that the nitro 4 tec does'nt drive in reverse. :mad:

What can i install to make my car drive in reverse :confused:

[krayzie]

central--there is NOTHING that you can put on to go revearse,NO nitro cars or trucks ( except the T-MAXX do to its tranny)go in revearse....

I dont see a pic. Maybe you can try again, i would like to see it. im getting mine on the 19th from ups.

[N2O Guy]

Why is it so dead in here? With such a great car to talk about..Ive got my little jewell all tuned in and all I can say is WOW! Krayzie you never told me how bad *** it really is with the nova...I knew it was gonna be fast but not this fast. If someone can eduacate me how to put a mpeg up ill upload some footage of this thing. As you all might recall I was going for 70mph with this...I cant control it to get there LOL. Its a powerhouse for sure. If you ever have a chance or opertunity to do this to yours GO FOR IT! You wont believe it. :D

[jayskiia]

does anyone know if there is a way to set up a belt tensioner for the front and rear belts on an electric 4 tec? I get kinda scared when i see my belt swell way out of shape and it is a brand new car!!!

[Aluma]

nitro 4tec bites ! two guys race them at our club races...and they cant get through a single lap without crashing or something falling apart AND they have monster oversteer.... they always spin out in the corners....anyone know a good setup for these guys...maybe I can help them out.... cuz they're breaking everyone else's cars!!!

[Skribble]

Just because they can't drive very well doesn't mean the 4-TEC bites. :rolleyes: Here's a little article RCCA did:

Steve Slayden
Traxxas Nitro 4-TEC Pro
ROAR On-road Fuel Nats A-main

Steve came in third, but for a privateer, his finish is darn impressive and proof that trucks aren’t the only nitro-powered Traxxas machines that can kick butt. Steve started with a Nitro 4-TEC Pro, but even an off-the-shelf Nitro 4-TEC can be dialed in like Steve’s (it’s a lot easier to start with a Pro, of course). Of all the race-prepped cars featured here, Steve’s probably shows the most attention to detail.

Setup:

Shock fluid:
FRONT, 80WT
REAR, 80WT
Shock piston: F, 2-hole R, 3-hole
Shock length: F, 66.5mm R, 67mm
Springs:
F, Traxxas black R, Traxxas black
Lower shock position:
F, Outer hole, R, Outer hole
Upper shock position:
R, Lower hole Caster/anti-squat F, 6°
Camber: F, -0.5° -R, 1.5°
Toe:F, 0.5° in R, 1.5° in
Swaybar: F, Position 2 R, Position 2
Steering-linkage position:
Outer holes on steering knuckle; outer hole on bellcrank
Rear camber-link position:
Lower inside hole on bulkhead; upper inside hole on hub.

[Aluma]

thanks for the setup info... I'll get it to these guys and see if that helps their handling. :D


Everyone else wants to ban them from racing cuz they keep breaking everyone else's cars as well as their own.

[Liquid_2]

HEY! ive got to get this thread back in track :)


heres pic of my 4-tec!!!!

http://community.webshots.com/user/w00t_1st


but what you mean about higher gear ratio how do i do this?
everything in my nitro 4-tec is stock except the fuel filter :) and the body next im going to get a tuned pipe with higher gear ratio but how do i change my gear ratio??? just curious!!

u said it can reach 60 or 70 with that?? whAA with any tuned pipe really???? WOW! +highergear ratio but wont my acceleration be slower if i do this or?
but how fast u think it will do with a tuned pipe?

[nitrodriver]

I'm gettin a 4-tec soon :D I've been talking to this guy and he's selling one for $175 RTR and its only been used about 10 times.

[Lewis]

:confused: I want to get a strong rugged nitro street car and i heard the 4 tech was a good choice, but i was wondering could make it do wheelies like a dragster with a few minor changes or modifications if so i would like to here what you think. If it not a good idea because it would cause problems what about fast speeds, how could i get the most speed, power, or whatever you guys think i should do to make it better in the beginning. Thanks. you guys are a big help.:cool:

[nitrodriver]

lewis im guessing your new to the hobby....
if you wanna go fast for not alot of money then get a 4-tec. theyre pretty damn fast with the trx 15 that comes with it, if you wanna go VERY fast you could get something like a 15 cv-r (if it would fit, not sure)

btw it would take ALOT of power to get this car to wheelie, and all you would do is mess up the rear end of the car... if you wanna do wheelies then get an e-maxx

[Possumbot]

don't pop wheelies with an on-road car. If ur looking for something thats onroad wheelies, check out the Bolink Little Red Wagon or Diggers.

Im trying 2 convince my dad 2 pick this for a nitro tc, nice speed, easy start, and lots of hop-ups. Its a 3 belt car right?

[nitrodriver]

yup

[Pr0k]

Hello guys, I am pretty new to rc I have a Landmax for rally and just odered a 4 tec for the road. I am sure I will have a million questions. I bought it used but the guy sent a video and the price was right.

[00G]

Hello... I have a problem. I have an OS RX-15 in my 4-tec and I rip those plastic drive shafts up often. Krazie or any others, do you have the CVD part #, and does it come with outdrives for the cvd's? I can't find it in the hobbiepeople.com or stormerhobbies. Thanks.... The car is insanely fast with this engine. Are there any replacement (plastic) 2 speed gears with a lower ratio for our cars????

[Pr0k]

Not perfect but was all I expected and more took it out for a run around the street today these little suckers are fast!

[Lewis]

Well, i am not new to r/c i used to fly planes which was fun but expensive to maintain and between us I have always loved r/c cars and trucks more than planes. I have an emaxx now it was awsome but I am having trouble with the batteries holding a charge or even getting charged. I have duracrap chargers the "Intellpeak" ones. The hobby guy said oh these great chargers and i had my doubts but i got them anyways. I hate having things break or go wrong with r/c stuff it always happens. But anyways, I want to get a nitro street car for the filler of time while the batteries were charging and i thought the 4 tech would be a good nitro car to buy. Oh, and that wheelie thing i was just curious thanks for the input. I appreciate it. I will drop a line later.:D

[spiderwc]

i live in rochester ny to i live off of west rige road.i own a kyosho gp spider wold cup.this car cost me a grand 1 month ago. i bought it from my boys at dans crafts and things curtis and john i dont drive it much cause i dont know any racers email me at shorty540p@yahoo.com so may bee i can join your team. i might know who you are .is this bob.... i think i seen you guys racing down at bishop kearney

[Skribble]

Pr0k, put some zip-ties on your engine heatsink. ;) That way it won't get scratched up. Also, you might want to consider a Fail-Safe just in case your battery goes dead. It happened to my 4-TEC and it went full throttle in to the curb. :( Whole front end was smashed, never fixed it. *Grumbles* Stupid cheapie batteries.

[Pr0k]

Hey dude thanks for the tips. I been thinking about a fail safe, have to decide if I want to really get into 1/10 scale or go with 1/8. Reason I say this is the 4 tec really runs on rails and all that but looks kinda flimsy in comparison to my Landmax. I guess I will have to run them both for a while to see how it holds up.

[ecatbox]

a failsafe won't help if your batteries go dead cause it won't have power to do anything...throttle return springs are $3 for 2 at the hardware store

[spiderwc]

should i get a yokomo gt-4 which does 61mph. or a 4 tec - and why:confused: :confused:

[Pr0k]

Yes but if there is a radio glitch or interference it will, and a return spring wont do ****. Granted not real likely but but both the fail safe and spring are useful. It depends on your situation. I need neither I do plenty curb checks on my own!

[big1s]

I GOT MY 4TEC TO HIT 65 ITS ALL OUT IT HALLS

[fmolzer]

4-tec fans ! I have a 4-tec pro with a Novarossi C12, (rebuilt and broken in, great power) paris pipe, Powerline aluminum parts in all the right places, MIP CVD:s all around (and 1 extra pair in the spareparts box), titanium aftermarket chassis, new painted body (pro painted, concourse winning body, never raced or even driven on the car.) 1100 NiMh receiver pack, new foam tires and enough spareparts to keep the car running for at least a couple of seasons. I used this car to win the National 200 here in Minneapolis in 2000. The car is completely rebuilt and has been on the shelf for a year, this is a great car. I would sell it with or without electronics. Without servos and radio, I would want to get about USD 450. If you are interested I can send you pics. I would estimate that the spareparts kit alone is worth around 300-350 USD. Extra belts, outdrives, all suspension components, pulleys, aluminium suspension arms, extra graphite upper deck, fuel tank, bumbers, ballbearings, hardware (screws, nuts etc), diffballs and diff pulleys and parts. This will a great deal for a very competitive car.

throw me an email if you are interested.

I have an RX-15 in my 4tec. I stripped those plastic shafts-outdrives. I just got the MIP CVDs. Now, I need to get another starter box.

What tires are those? Foams? They almost look like they're off of a 1/8th onroad.....

That's what I was thinking ..:D Anyone know any places that still sell the Pro? :confused:

This thread died but hopefully some one can answer my questions.

1. If i get the rtr kit, is the tq radio fine for it or is it a waste of money to get it with radio?

2. How is the stock handling?

3. How often have you had to replace your belts? Are they covered? Durable?

4. What do dislike about the car? Like?

5. How would this car do aganist and rs4 3 ss ntc3?

6. What problems occur right out of the box?

7. How durable is the car out of the box?

[RcLaB1]

what do you guys think of the new 4-TEC coming out
on october 5th.......it has the new 2.5 motor in it......

[ponky_wonky]

the new nitro 4-tec won't exactly be race legal:p
the 2.5 stands for the displacement

ie. 2.11=.12
2.5=.15
3.5=.21

most oraganized races don't allow .15 size engines in the Sedan 4WD touring car ".12" class

it sound pretty cool none the less, over 60 mph!:D

[save1992]

you're saying the 2.5 is really a .15 engine? don't the 4tech already come with a .15:confused:

[ponky_wonky]

yes, but the 2.5 pro is said to have 60% more power,(god knows how)i personally dont think that their speed calculations are correct, i'll have to see it to believe it

[duratraxxas70]

Does anyone know where I can get aftermarket parts for the 4tec. I just bought a very used pro 4tec and I need some parts. I am willing to buy new or used as long as they are in good shape. I need a chassis and the carbon fiber rear shock mount and a 2 speed clutch assembly plus other misc. parts. Thanks guys keep the thread going!

[thebreathtaker]

i heard that a cvec tuned pipe + a sway bar + boost bottle can make our 4 tec 30% more powerful and good conering..
any one have Cvec pipe? i woud like to buy one to install to my all new 4 tec...if u have it...please email me...s_weng@yahoo.com

i just brought my 4 tec week ago,already run (break in) with 5 tanks of 10% nitro.. i found that there was leaking of il/fuel around the carburetor,the engine and the bottom of the car....so headache.this is my all new first ever car...how come like this!?
is this caused by the connection between the carburetor and the engine not tight enough ? do u all face this leaking problem with ur 4 tec?
Please help and thanks a lot for this forum!

[RcLaB1]

is the new Pro tec 2.5 a big block .15 motor?

or is it a small block like the O.S. 15 CV-R

please specify.......


also, with some gearing changes and a
better pipe, will the new 2.5 Pro tec reach
65 to 70 MPH......or is it impossible with that new 2.5 motor?


thanks

Hey, i have a nitro 4-tec pro with a picco p-12, airtronics mx-3 radio, and hitec servo's. My car hits 70 with stock gearing, and 0-50 is 3 seconds.! 0-60 is probably around 4 or 5. I am an average racer and all i have to say is this car rocks! It can stack up with any tc3 or kyosho. Sorry, i got no picks. I have the stock body, bmw m3 body,clk dtm body, and vw beetle body.

[tmaxx_1]

it is in my tmaxx. this engine is incredible. they should be coming out in stores this week(the new 4tec with the 2.5) it makes the 9 pound tmaxx go 43mph, cant wait to see it in the 4tec. i have to get one. it also does wheelies. i have no problems ecept it does get up to the 300 degree temp if you dont keep your eye on it.

[xevious454]

I just recently broke in my new nitro 4-tech with the 2.5. This car is fast and awsome. Unfortunally I have a prob. with my radio or onboard batteries because it keeps going out of controll. Hit the curb 3 times already, but still no broken parts yet!

[Quinn5151]

I just broke in one of the new Nitro 4-Techs with the 2.5pro in it and it is pretty amazing. I have a Nitro TC3 with a 2-speed tranny, all graphite and ti. and an O.S CV-RX .15 in it and I'm pretty sure the Traxxas will walk away from it on the top end in stock trim. It handles pretty well to. I never would have believed it. If your looking for a fast ready to run parking lot racer this is it.

[TitansGT4]

I'm gettin 1 of these bad boys for christmas, and i heard its great. I'm gonna be racing w/ some friends in a parking lot, they all have GT4's. Can't wait to make them look stupid...(btw GT4 is in my name because i used to hav 1)

My friend put a 2.5 in his 4-tec. He also has a radar gun, it is raining right now, so when it stops we are going for a speed test. Ill be back later with the speeds.

[T-maxxer1013]

Ok. I have the speeds. The first run came out to 49 mph, that is just getting wamred up. 2nd run was 53 mph. 3rd run was 57 mph. and the final run was 59. This is in very humid weather. I imagine that it will do 60+ like traxxas states, i know it will. The thing is a beast. I am actually very interested in buying one.

4tec with .15 tx pro
HPI rs4 3 rtr

Which one should I keep to mod be honest.

HPI Has a 2 speed in it now also.

[joke_one]

i have both but i think that the hpi is the one you should keep just because its shaft driven so it more durable and its also way easier to work on, i love my 4 tec but the hpi has given my no were near as many problems

Originally posted by joke_one

you can do one of 2 things, do like what the 4-tec pro has and just add bearings to the stock bellcranks,remove the bushings in there and add (4)5x8x2.5mm bearings. this should help the bellcranks to operate much more freely and much cheaper than buying any aluminum bellcranks. or, you could get this aluminum bellcranks made by powerline racing:
http://www2.gpmd.com/image/p/plrc1009.jpg
I have them on my pro and just to let you know, they do not come with any bearings but with plastic bushings. the bearings that come with the pro's bellcranks fit into the powerline ones, but has a little slop. I would recommend just sticking with the stock bellcranks and just add the bearings.

[default_uzer]

Hello, ever since I put all aluminum on my nitro 4 tec, dumped the ez start for a pull start, it seems to pull to the left all the time, I cant figure out why? Any ideas? Is it too lite now? Also where do you guys get the MIP CVD's for the 4 tech?
Thankz:)

[PhillyNitro]

did you try centering the servo?

[default_uzer]

I think that I may have, but I will center it again, and if that is not the problem, any other suggestions? Thankz!:confused:

[quisanoj001]

try checking the outdrives that are attached to the diffs. if one is loose, it could cause the car to pull to one side. another thing to check is that you do not have the wheel nut overly tight on one side that the other, if it is too tight it may cause some binding.

[default_uzer]

I will try that out, thanks alot, I appreciate the tips!:)

wow triple post..

yes its a decent basher or racer and I love mine but it is limited in hop ups. I personally would have went a different route if I could do it all over again. I like to add parts to my cars and your very limited with the 4tec..

As far as handling I recommend getting the optional sway bars.

Other than that its a wonderful car and replacement parts are very easy to get.

Thank you im sorry for the triple post my internet was f*n up cable hehe but sorry again and thx

sumone please help, theres a silver wheel thing under the airfilter and carb, when i use the ez starter the silver thing will get stuck untill i push it round with my fingers, it would then go round a couple of times and get stuck again, this doesnt happen when the glow plug is not in, PLEASE HELP wot the hell is going on

yeah new engine DOES make a difference but i always say:



GO HPI!!

How many gallons does the TRX2.5 last for

[TitansGT4]

i have a 4tec 2.5 and i can't keep it in a straight line. What tires do you think give enough traction for this damn thing 2 stay straight?

[Rob d]

try the hpi x pattern belted radials they seem to be the best

[ibanezcollector]

buy the optional sway bars too.. There needed not optional LOL..

Unfortunatley I have to sell my hopped up 4tec pro with novarossi.. It was my baby and im going to miss her..

Good luck guys and gals with the 4tecs.. See ya at another time..

by the way the 4tec pro is on ebay for 3days 1 dollar no reserve.. 5 bodys, brand new ofna starter box with all the goodies, etc etc..

Rather see it sold to someone here than some jackass..

[TitansGT4]

do you think if i put foams and a high downforce wing in my 4tec, it would be more controllable? because right now it's all over the place and it's really annoying

[TitansGT4]

thanks for answering:p . I bought Elligi foam tires, mediums in the back and firms in the front, and i've got a wing designed for sprint cars on my mustang body(i'll have pics soon). I'll be able to tell you if it's better when i run it tomorrow

[TitansGT4]

.It handles really nice, its really stuck to the ground now. i still crashed it though:p ! Got a lil carried away on a long straight thats kinda narrow, and i hit a curb at lik 50 mph. I broke a rear hub carrier, a dogbone, and a rear A arm, all of which im replacing w/ aluminum as soon as my order comes in, except the dogbones, Shiny CVDs are goin in there

[save1992]

have any of you raced your 4 tec against a streetforce if so who won:D

[DaniandD]

I have a friend who is telling me the size of the glow plug for the 4tec engine is different from a standard glow plug. Can anyone please confirm whether the threads are actually different?

[jcats]

A friend of mine just got the 4tec.
It's nice but it stalls after doing a couple of high speed runs.
Tried many different settings to no avail.
It seems the engine runs really really hot!!!
Everything is still stock....
Any suggestions????
We are stumped.

Your help will be very much appreciated

[Ford850]

Do I need a new motor mount to fit a O.S. .15 CV-X into a 2.5 4-Tec.

Thanks

[save1992]

my son in law has this car and its really fast i'm thinking about getting this car a ld3 or a neo 4300 which one would you get:confused:

[Maxxxxst]

Can a Nitro 4 Tec leave tire marks on the pavement easily? I have a Duratrax Max ST and when It was stock I could spin the tires and make black dounuts all over a parking lot.

Is the Nitro 4 Tec 4wd? and do You think it's the best in it's class? I'm looking to buy a Nitro car soon.

[TitansGT4]

i have the Nitro 4tec it's MAD fast but it doesn't handle that great, it's really durable though. If I were you and i wasn't racing i'd get an RS4 3 that's what i'm doing

[JeffRS4_3ss]

my buddy [TeKTRiKz] owns a nitro 4-Tec Pro1.5. he ordered a aluminum machined header, swaybars, and a machine aluminum backplate for his engine today. He is going to buy a pro diff[aluminum] for his car. however, he is not sure on the gear ratio he should use. he is looking for the best gear ratio to get the most speed out of his car.
the next thing would be tire compounds. what is the best compounds he should use? all help appreciated, thanks.

[R3VoLuTiOn]

how does this car handle

[vtl1180ny]

I just picked up the 2.5 4-tec a few weeks ago and this thing hauls butt... The 2.5 is a little tempermental but I'll find the sweet spot and get it tuned to my liking soon enough... Has anyone put a tuned pipe on this motor yet, what did you use and did it make a difference... Those stock tires suck, lasted me maybe a week... I put a set of 26mm X-paterns and it was still a little loose, now I have 30mm medium foams and the car really hooks up... It's still a little twitchy though, maybe those sway bars are a must have... I set the camber and toe in to factory specs, as soon as I have the time I'm going to play with the shocks and camber/caster/toe in and see what I can do... Does anyone have a setup that works, besides the one posted here already? Great little car, just have to throw an FM radio in it so I can use my Futaba and have a bit more control...

[txt-30]

Anyone use 30% blue thunder regular formula in there 2.5 tec? Any faster?

[vtl1180ny]

May take a few months for an answer... I'm using the traxxas stuff still... I have some 30% heli fuel I should try...

[boostspike]

what happened to this thread... doesn't anyone own a 4-tec anymore....????:(

[metalry101]

Hey, I might be joining the family here. The local track has a used Nitro 4-tec 2.5 for 100 bones. He says is still runs, and all it needs is a radio. It needs to be cleaned up a bit, and I'd have to get a reciever pack, cuz AA's suck, but for 100 bux, I'm thinking it's a good deal. It also has some foamies on it, been used, but not chunked at all, and still w/ lotza life left. I don't know a lot about Nitro, and this would be my first Nitro car (I've got lotza electrics: E-Maxx, 2 Micro RS4's, TB Evo II), but I'm thinking the EZ start would be a good thing for me, so I can learn the basics of the car before I strip it down for racing next year. Anyways, anything I should know about the car, weak points, etc, that I would want to upgrade or fix before I drove it much? And what all equipment wise would I need? Fuel, fuel bottle, temp guage, anything else to start out?

[boostspike]

Originally posted by metalry101

not a bad deal for $100. you'll enjoy it.. the car is fast.. well, you'll need fuel bottle, nitro fuel, glow plugs, temp gauge would be helpful.. EZ start is great for beginners.. my advise is to just run the car and then make adjustments afterwards... make sure you ask ppl at your track questions and help..

[metalry101]

Oh ya, forgot about glow plugs. Duh, I know it already has one, but spares would be a good idea.

[mclaren_592]

Who here thinks they have the fastest nitro 4-tec. I have been working on mine and kinda want to know what you guys have done to your rides and how fast they go. :cool:

Damn, how much faster can these babies go :D . i have a stock 2.5 and i'm running outta real estate to run this car... :D

what can i do to have more low end power???

[Crawl-N-Clod]

I have a Nitro 4 Tec with an Orion Wasp.12 rear exhaust and cvec pipe and was wondering if anyone can tell me what header I need to get:confused: :confused: :confused:

[the-one1]

dead threads, no fun :)
well, just got a 4-tec too for x-mas, i wanted either the n-tc3 or n 4-tec, but the lhs didnt have the tc3, so my gf bought the tec instead, but i'm happy. It was one of my choices cuz my bro in law has the older 4-tec with the pro-15 and friend has one with the trx-2.5
I have a rs4 3 and comparing the two, i'm much more pleased with the 4-tec, faster and handles better stock for stock.
Only complaint is that its a PITA to work on, to get to one part, you have to take half the car apart. Just to get to the front belt, you have to take apart the arms and whole bulk head.

[the-one1]

doh!

[the-one1]

dang

[the-one1]

darn. weird :(

[boostspike]

yeah... this N4tec thread has been dead for a while now... for questions and help i usually just goto the message board at Traxxas. com. but RCZ is great for everything else:D .

I also go there too, but kinda dead too.

yeah, but atleast your N4tec questions would be answered. :D

[OBLIVION]

put optional spur gears on your car, and it will perform like a rocket...
as for traction, 30mm, 35shore rear foams will work well, when combined with 26mm 40shore front tyres..
CVEC muffler will really give you a performance boost, and if you have the old pro.15 motor take it to a gokart shop, and have it ported + polished.. it will run like a demon then..

replacing the steering servo is a must, because the traxxas one is just too weak + can never keep your car in a straight line..
get a servo like the KO propo 712, or Hitec 625MG is probably the best option..

as for aftermarket hop-ups, there are many,many good ones out there if you look on websites like towerhobbies etc..

[boostspike]

where is everyone???:)

[the-one1]

At the Traxxass site, and also its winter, no much ru time. But i did get to run mine yesterday and today de to 40 degree weather lately. Its fasst, but I got much tweaking to do.

[boostspike]

besides the car itself, you'll need things like AA batteries, fuel, fuel bottle, 7.2v battery pack (for the EZ start), and charger for the battery pack.. the car is pretty nice for your everyday parking lot racing/bashing.. since you are a "kid".. i do recommed watching the DVD and reading the manual b4 starting up the car... and follow proper break-in procedure

other thing you should get:

fuel filter, tires, after-run oil...

Yo um i only have 400 dollars and im wondering if I should get this car because if I crash my allowense is 6 dollars a week?? 24 dollars a month. just wondering if u crash a lot? :confused: :confused:

[fumbel47]

my son wants to get one of these cars but i need to know how much the maintenance is going to run.i would imagine one nice wipe out must run about 150.00.would you mind sharing some wipe out stories and what the damage cost ya? plus how often do you polish the dust????

[Lagwagon]

You must polish the dust after each run!! Luckily I've never wiped mine out!! But I've heard of guys who had to spend loads after crashing their cars!! I had a minor crash the first day I ran it and it cost me the equivelant of $20. You shouldn't worry about what its gonna cost you to fix it....you should worry about all the money you are going to spend on hopups and extra bits and pieces that goes with this hobby!! But once you're in, you will never want to get out!!

[SWINGRRRR]

NTC3 guy here, but Im trying to fix a buddy's 4-Tec.
Can somebody tell me where an on-line manual is? I need some P/N's.

[the-one1]

The manual should be on traxxas' site.

[SWINGRRRR]

yeah, I found it, but it wasnt what I needed. Ill keep looking.

[rc addict]

my nitro 4 tec exploded.

[rc addict]

due to a fuel tubing accident, the gas got all over the cylinder head and caught fire, the cylinder case blew up and flaming parts went everywhere because the gas spilled all over the place, i had to dive away from the burning wreck because it was coming my way when it caught fire, i had to check what was wrong, i think i had a hole on the fuel tubing, but it was melted after i checked. im gonna go build a nitro tc3 factory team kit instead later... hope it doesnt blow up too. im gonna sue my lhs for selling me faulty fuel line crap. lol

[Lagwagon]

I would be well pissed off if my car had to go up in smoke!! Sue them mate!!

[smidtdoggmotors]

dose any one out there know how to port and get more power out of the traxxas 2.5 motors.

[monkeygutz69]

is the new Pro tec 2.5 a big block .15 motor?

or is it a small block like the O.S. 15 CV-R

please specify.......


also, with some gearing changes and a
better pipe, will the new 2.5 Pro tec reach
65 to 70 MPH......or is it impossible with that new 2.5 motor?


thanks
2.5 is a cc (cubic centimeter) designation..It is still a .15 (cubic Inch)it is a marketing thing...2.5 (cc) sounds bigger than .15 (cubic inch). The new 2.5 is a hopped up .15. We have one in the T-Maxx and it blows the old trx15 away!!

[atchipmunk]

Man...dead in here and on the Traxxas site. Well, i'll be the new owner of a Nitro 4-Tec Pro soon with a TRX 2.5 engine. Have lots of experience with electrics but this will be my first nitro car. So what pipes do people recommend for use with the TRX 2.5 engine? I've heard CVEC and Paris both make good pipes for the TRX 2.5. What's the best out there? Thanks.

Atchipmunk

[the-one1]

LOL, this thread is really kickin' it, isnt it. I dont know about pipes for the 2.5, but I'm pretty sure all the prior posts in this thread has answered that question, also traxxa sites has alot of info too, I go there sometimes too, but like you metioned, it has died down quite a bit. Nice to have another 4-tec owner!

[Fantom_4-tec]

i have had my 4-tec for about 3 years. Right now, everything on it is upgraded accept for the chassis. it has:

Powerline shocks
Losi springs
MIP black CVDs
HPI black split 6 spoke rims
HPI X-pattern tires
Traxxas Pro ball diffs
JR XS3 radio gear
Traxxas blue pullys
Fantom FR18 engine
CVEC tourqe pipe and
HPI Saleen S351 Mustang shell

This thing spins all 4 tires off the line and just keeps screaming.
Can anyone give me the Powerline website so that i can get hold of some aluminum.
Thanks alot. -Mike

[the-one1]

Tower hobbies sell powerline stuff. http://www2.towerhobbies.com/cgi-bin/WTI0002p?&M=PLR

[Fantom_4-tec]

thats awesome but they dont have everything.
Thanks -Mike

[atchipmunk]

Anyone know if any companies make a titanium screw set for the Nitro 4-Tec? I'm looking to drop some weight from my 4-Tec Pro LE and it already has the CF chassis parts and titanuim hinge pins and turnbuckles, etc. Titanium all around should help a bit in the weight department. Can anyone point me in the right direction? Or at least to a place that makes hardware in titanium so I can piece together a set for myself. Thanks in advance.

Alvin Caragay

[carmaniac101]

if anything go with a tx15 super charged, but be carefull to line all the pullies perfectly straight before and after races, it should at least push 90-100 mph. it has more torq then anything anything else realy. If anything go with the tx15, it has less rpm but more torq. You want more torq because you are probably going to use a high gear ratio to produce that 70 mph.

With the trxpro 15 you can do 70, put an aluminum tuned pipe on and use a high gear ratio and you will reach 70 or beyond and you will have some money in your pocket from not buying the engine. The pro-15 is almost the same as the nova. you wanna buy. if anything the trx pro 15 has more power. currently you are using a stock pipe and a stock gear ratio right? if yes, get the aluminum pipe and higher gear ratios.

[carmaniac101]

yes the stock traxxas radio system but if your talking about steering go to rour local dealer and get sway bars.all u peeps when u buy a 4-tech dos it come witrh control!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!

[carmaniac101]

add wight to the corners of your 4-tecHello, ever since I put all aluminum on my nitro 4 tec, dumped the ez start for a pull start, it seems to pull to the left all the time, I cant figure out why? Any ideas? Is it too lite now? Also where do you guys get the MIP CVD's for the 4 tech?
Thankz:)

[carmaniac101]

add small amonts of wight to the corners of the 4-tecI will try that out, thanks alot, I appreciate the tips!:)

MY 4-TER LEAVES MARKS THROGHOUT THE STREETSCan a Nitro 4 Tec leave tire marks on the pavement easily? I have a Duratrax Max ST and when It was stock I could spin the tires and make black dounuts all over a parking lot.

Is the Nitro 4 Tec 4wd? and do You think it's the best in it's class? I'm looking to buy a Nitro car soon.

[rwviper2]

I have a traxxas nitro 4-tec, and i bought an ofna hyper .21 8 port to put in it. I have no clue however as to what transmission to get for it. I want to get either a 2spd or a 3spd for it. I also want the ratio fit for high speed. I was thinking maybe putting a schumacher fusion 3spd on it? does anyone know if this will work with the hyper .21 8 port or have any suggestions as to what transmission will work?. My goals are to get the car to reach at least 80mph. thanks for your help

[JoshsTL01]

hey yall- i got a TL-01 right now that im slappin in a 15 turn speed gems motor. it should have some good speed by then, but i want an inexpensive car that can fly. im lookin at the nitro 4-tec. first of all, what are the neccessary upgrades out of the box? and second, try to convince me to get this, cuz i want it bad!! i work at a hobby shop, so i can get a discount off parts, but i would buy from Tower.

[JoshsTL01]

well i just ordered my nitro 4-tec from tower hobbies for 280 with 2 day delivery. im excited to get it. so wat are the first hop-ups i need to get?

[JoshsTL01]

damn this thing is sweet. i was flyin down the parkin lot with it and i only got up to like 50 and had to slam on the brakes. GREAT CAR!!

[nitromutt]

a couple of us run once a week n 4 tecs in new rochelle at 5 at home depot expo if any one is in the area the more the better

[nitromutt]

wow no one around

[300ZXZ31]

Liquid_2-To change your gear ratio you will need to get a clutch bell with a higher no. of teeth on it. Also i seriously doubt you would get 70 with a pro 15 a tuned pipe and a change in gearing. Take a look on the traxxas forum people with .26 in there tecs, stupily steep gear ratio's and pretty much every other hop ups for the 4 tec are only getting about 77. by the way im not bashing the 4 tec in any way, i have one and its great I just think your a little optomistic about the top speed.

[JoshsTL01]

this car is fast enough stock, you really dont need any hop-ups unless you're lookin for low end torque, or have a humoungous parking lot.

[JoshsTL01]

nobody on? come on people, i know you Nitro Tec'hers are out there.

Sounds like you wanted a fusion to start with.....you might have some difficulity fitting a .21 big block engine, in a small block location......

It might be easier to drop in a O.S. 18TZ Engine:

Just a thought......

[JoshsTL01]

http://x4.putfile.com/5/14812462588.jpg
i shortened the fuel line and back pressure line just so it was less mess and fuel arrived in the engine faster. replaced the ez-start system (5.25 ounces) with a pull start (1.25 ounces) and installed a fail safe unit. what else should i get? im thinkin about aluminum pulleys and the full carbon fiber accessories (4 or 5 pieces).

[Y2KGTP]

Does the 4-Tec use the same engine as the Revo?

[JoshsTL01]

Does the 4-Tec use the same engine as the Revo?
no, the Revo has the 2.5R engine. better cooling head and carb-

TRX 2.5R Racing Engine*
• New PowerTune* cooling head
promotes even heat distribution.
• Composite slide carb.
• Multi-port rear exhaust.

I also had a local track owner say these cars are not as competitive as a NTC3, or Serpent 710.....what do you guys think?

handling is not as good as those, but in a straightaway, a tc3 would get left in the dust. besides. theres things you can guy to make the handling improved.

Thanks so much for the links and numbers. I really am grateful for them so now my friend can hook up his car. Is there a front graphite shock tower anywhere, do they even make one? Cause I never saw it anywhere.

[Y2KGTP]

Any suggestions? I really like these cars for my boys....I love the EZ-start AKA Revo............

[JoshsTL01]

they dont make a front graphite shock tower unfortunately.

for handling, i suggest these things-

Part #4875 Sway Bars (front and rear)

Part #4334 Reactive Caster Wedges (2)

Part #4336X Stub Axle Carriers, Front (l&r)

Part #2658 Aluminum Big Bore Shocks (short) (2)

new tires, although the nitro 4-tecs stock tires are good

check out the traxxas web site, theres lots of good hop-ups with part numbers.

I dont think that they would notice a difference. About the Reactive Caster Wedges, do they actually help or no?

[Y2KGTP]

Does anyone race this car with success? Just curious....I guess I can make it into a bump start down the line....

[JoshsTL01]

out of the box its not bad, it just has so much power that its hard to keep it from fish tailing when you floor it. but is that really a bad thing? id rather have power over handling. the caster wedges might help a bit, but not enough to really notice. youd have to have all these hop-ups installed to really notice a difference. for better handling, just try to lighten up the car. thats for better all around. im hopin to shave off 5-6 ounces with my pull start and all the carbon fiber and aluminum pieces. plus it looks cooler. ill post some pics in a few weeks when i get the stuff in and installed.

[Jetskiboy77]

Please do post some pics cause id like to get an idea of what my friends car will look like when were done with it.

[JoshsTL01]

no problem. i got em on order at my store, so they should be here within a week or so. might take me a while to get it all installed. i got all this stuff to install:
FRONT ALUMINUM PULLEY SHAFT
GROOVE ALUMINUM PULLEYS (15 and 20)
FRONT GRAPHITE TIE BAR
Graphite Upper Chassis Plate
Graphite Rear Brace
Graphite Rear Shock Tower

hey i guys i know this is a little off topic but i thought perhaps some of you guys may be interested in a nitro 4 tec for parts or fix
car has no wheels reciever ,body , transmiter
. the motor is the pro15 but it seems to be locked ? i got it in a package deal and have no use for it if anyone is intersted i can email picks . would take a reasonable offer on it . i also have some vintage on and off road electric cars also 4 sale thanks ,bigv10

Oh....I'm well taken care of......I spend 4-5K a month on hobby stuff.... :D

lol, Thats more than what ive spent in the last three years on this hobby, and I thought I bought a lot of stuff. :)

[Y2KGTP]

lol, Thats more than what ive spent in the last three years on this hobby, and I thought I bought a lot of stuff. :)

Well, I buy stuff to resell it.....the problem is that the temptation is there to keep 1 of the 4 for myself....



......I think I'm going to keep the red one.......or purple? help? :D

[Y2KGTP]

they don't make a front graphite shock tower unfortunately.

for handling, i suggest these things-

Part #4875 Sway Bars (front and rear)

Part #4334 Reactive Caster Wedges (2)

Part #4336X Stub Axle Carriers, Front (l&r)

Part #2658 Aluminum Big Bore Shocks (short) (2)

new tires, although the nitro 4-tecs stock tires are good

check out the Traxxas web site, theres lots of good hop-ups with part numbers.
http://www.traxxas.com/products/nitro/n4tec/trx_n4tec_accessories.htm

Any suggestions on the best place to get all the graphite parts? I'm swapping in my MX3-S radio system to one of the 4-Tec's, and figured I would upgrade a few things prior to break-in.......


Also....what are the bearing sizes for the steering posts? The stock bushings are horrible, I can tell that already....

[Jetskiboy77]

I think I would go for the red body one if I had the choice.

you'll get more hits in the buy/sell/trade forum. i want a new one, but not a pro 15.

try towerhobbies.com for the graphite parts. they have everything there, and i provided links.

Thanks....I'm just not a big fan of Tower, but I do want as much graphite & titanium as I can get.....I weighed the pig at 3lbs 15oz as it comes out of the box (no receiver batteries even) so it needs a diet.

what does a NTC3 weigh anyone know? or what hae you gotten your car down to? I have a nice digital scale, so that helps.......

[JoshsTL01]

really? my 4-tec weighs 3lbs. 10 ounces WITH the rechargeable battery pack, which is a bit heavier than 4 batteries, for the reciever. Id like to get it down to 3lbs. 8 ounces when im done.

what kind of scale? I have 3 4-Tec's that are still assembled....I'll see if they all weigh the same.....this included the body as well....

[JoshsTL01]

its the kind they use to weigh postal stuff. it goes from 0-6 pounds i think

[Y2KGTP]

Well, I just listed my first bunch of parts on ebay for the 4-Tec.....I am still trying to decide to keep 1, or maybe get a NTC3.....

My main concern on the 4-Tec is the unprotected drive belts, and the poor mounting locations of the receiver, and battery pack.

[Y2KGTP]

Ok....if I am going to keep it, I need some graphite parts:

I can't find the upper chassis anywhere....

Part #4823X Graphite Upper Chassis Plate/Hardware
Suggested retail price $36.00

Part #4826X Graphite Rear Brace
Suggested retail price $10.00

Part #4317X Graphite Rear Shock Tower
Suggested retail price $7.50

[JoshsTL01]

try your lhs. if they are good at all, they can special order all these parts for you. thats what i do, of course i work there, so its a bit easier. i know you dont like tower hobbies, but heres the links anyway-
Traxxas Upper Chassis Graphite (http://www2.towerhobbies.com/cgi-bin/WTI0095P?FVSEARCH=4823x&FVPROFIL=++)
Traxxas Rear Brace Graphite (http://www2.towerhobbies.com/cgi-bin/wti0095p?FVSEARCH=4826x&FVPROFIL=++)
Traxxas Rear Graphite Shock Tower (http://www2.towerhobbies.com/cgi-bin/wti0095p?FVPROFIL=++&FVSEARCH=4317x&FVPROFIL=++)

even if you dont like tower, its the best place to get parts, besides your hobby shop. they usually have stuff in stock. you can try www.buytraxxas.com , but they are out of stock for some of those graphite parts.

I just made another list of hop-ups to buy:
4352X Stub Axle Carriers Rear=$17
4336X Stub Axle Carriers Front=$17
1747X 4mm Blue-Anodized Flanged Lock Nuts=$3
4486 Aluminum Tuned Pipe & Header=$42

Thanks....I did some searching, and just can't find the parts anywhere in stock......I'm thinking of possibly getting a NTC3 Team kit now, and seeing if I can get the TRX 2.5 with EX-start to fit........just a thought

[JoshsTL01]

that would certainly be interesting, but i dont know if it'll work. HPI hasnt figured out how to do motors quite yet, at least as far as quality. if i were you i would just stick with th 4-tec, and look into some handling mods. like sway bars, and lightening everything up.

I was thinking of sticking with it, but I just don't like the lack of graphite parts for the vehicle......my main reason for purchase was the EZ-Start system, to make it easier for some parking lot bashing, but I would like the ability to race competively as well.....

I just don't like the idea of a reciever & batteries stored in a baloon tip-tyed to the chassis........reminds me of my Tamiya Frog I had when I was 10 :D

[JoshsTL01]

i just got the car cuz it was so damn fast and easy to tune. plus, theres lots of parts out there. traxxas is a great company, and i think they have the best products, as far as nitro goes.

[Y2KGTP]

Well, I ordered a NTC3 + RTR today after all....I liked the black body it comes with....should have it sometime next week, best guess......then I can compare both side by side and make a choice.....

http://www.teamassociated.com/shusting/CatalogHub/kitspecs_ntc3/2042/2042_BlackBody.700.jpg

[JoshsTL01]

good idea. but are you gunna run the TC3? have you even run the 4-tec? i thought u were just sellin them. you really have to drive em to tell which is best. but if you do, its gunna be hard to sell.

[Y2KGTP]

Well, my buddy at work has a NTC3, so I figure I would get the same....I plan on seeing if the 2.5 engine & EZ Start will fit....for parking lot bashing....

If I decide to race, I'll just pick up a RB .12 or something similar....as I have a starter box that should work as well.....

[JoshsTL01]

i would hate luggin a started box around. but they do save weight. i just prefer a pull start.

[Y2KGTP]

Well, the starter box would be if I was racing, with a different engine.....for playing around, I will see if I can get a TRX 2.5 engine with an EZ start system to fit :D

[JoshsTL01]

the only problem is the ez-start needs a place to be mounted for the wires, and the electric motor is bulky, so it gets in the way. im thinking you may have to modifiy the TC3 to get it to fit, but im not sure. that would be pretty cool though. good luck with it.

[Y2KGTP]

Well, I started breaking in a 4-Tec this afternoon, and have noticed a few things I'm just not happy with on the car...(I have a JR radio with 5 cell 1100mah battery, and failsafe instead of the stock electronics)

Receiver mount:
Anything better I can do besides a rubber balloon? I need to find a small box to mount the receiver in, as the current setup is just a poor design.

Receiver battery mount:
Same complaint.....a 5 cell pack just does not fit well inter the front right of the car. I have 2 zip tyes holding it in place, and it seems to rub the belt slightly, as I have a small wear mark.

Clutch-bell:
I hit a small dip, and the car just stopped moving.....it seems that I tossed the 1st gear off the clutch-bell :confused: after a bit of looking, I found it, but it was oblong shaped.....no clue how it got so deformed (I'll take a photo later)

Rear belt guide:
Well, the rear belt guide that sits on the 2 speed trans got chewed up a bit, but I think that was from the clutch-bell 1st gear letting loose, but I replaced it as well.....the teeth were fine, just the inner side of the guide was chewed a bit.(I'll take a photo later)


The best part was the EZ-start.....it was really nice not have to have a starter box\glow plug driver to get it going for my 12yr old......for parking lot bashing, this is the best solution so far I think.......

the balloon does fine for me. with a zip tie around it, it stays in fine usually. im gunna have to put another zip tie on to secure it just in case. i have a 5-cell pyramid pack that fits fine in there. doesnt run at all either.

Hmm....my 5 cell fit ok when I first installed it, then shifted slightly after I ran it for a bit.....I'm sure I just need to put some doublesided tape un the underside.....that should help keep it in place with a couple tip-tyes, I hope....

I'd like to get, or make a receiver box to keep the receiver protected, and clean up some of the wires......any ideas for this? It just looks better, and makes it easier to swap crystals for the kids, if needed.....

[JoshsTL01]

do you want a closed box, or open on the top? check HPI, they have some that might do the trick. if not. look at the t-maxx reciever box. it should fit perfect, but it has 2 screws that hold the top down.

I'd like a closed box....I'm going to check out the small storage container idea......something that is easy to open to change crystals, but also keep the gas\dirt out....

[JoshsTL01]

i just found a bunch more stuff from powerline for the 4-tec. its all aluminum parts. heres the list:

LXMW89 Powerline Front Arms/Hinge Pins 4-Tec 21.99
LXMW97 Powerline Blue Shock Nitro 4-Tec 28.99
LXXD73 Powerline Front Gearbox w/Tower 4-Tec 39.99

LXMW96 Powerline Front Lower Arm Holder 21.99
LXMW90 Powerline Rear Arms/Hinge Pins 4-Tec 21.99
LXMW95 Powerline Steering Bellcrank 21.99

:D

[JoshsTL01]

it's gunna cost me about $450 for all the parts i want...i'll have to limit myself for now.

[Y2KGTP]

Well, after running a 4-tec & a NTC3 side by side, I think I like the NTC3 better.....the best feature of the 4-Tec is the EZ-start for the kids.....

also, the radio box that comes with the NTC3 would work perfect on the 4-Tec.....I'm going to try to find a couple for myself......


Steering seems little sloppy.......the car does not want to self center after a turn.....I need to counter-steer to correct......think I just need a stronger steering servo ?

[JoshsTL01]

no, u just have to learn to straighten it when u get out of a turn. it will never be perfect, just try not to slide around too much. so are you keeping the 4-tec? or are u selling that? it would be good for the kids with the ez-start. you can always keep it stock, and its still fast, which is great.

[Y2KGTP]

I guess I'm comparing it to the NTC3.....when I let go of the wheel on the NTC3, it goes perfectly straight.....the 4-Tec will continue to curve a bit if the wheel is let go, unless you counter steer a bit to compinsate......I'll have to see why this is happening......


Oh, I will keep the 4-Tec for the kids, it just gives me a challenge to tweak it a bit for better handeling.....

[JoshsTL01]

yea, everytime i tell someone i have a 4-tec, their always impressed by the speed, but tell me a TC3 is better because of the handling. i dont race, so it doesnt bother me. try some sway bars and the big bore shocks.

[rc addict]

hey my middle belt snapped a few weeks ago, connecting the front pulley to the rear, so now its apparently rear wheel drive, can i still drive it like this? i floored it after the middle belt broke, and it left skid marks and burnt rubber on the pavement :)

i also think my slicks were a little worn

[rc addict]

sorry for the small pic my camera is 5 mega pixel and i had to resize it so it would fit the kb limit

[rc addict]

ive never cleaned out the engine internally, ive let it sit for months at a time, ive never removed parts to clean the chassis and those hard to reach places...YET this car still runs like the day i bought it, and it has held up since, should i rebuild the motor, and will i see a significant increase in performance? also can i leave the middle belt out since it snapped? i can see some rwd donut possibilities

[Y2KGTP]

Well, I found a possible solution for the radio box, I'll take some photos when I have it set up.

On the main long drive belt.....looking at the car, it seems like it would rub under the throttle\brake server arm.....should I raise the servo a 1/4 in ?

[JoshsTL01]

rc addict-your handling decreased dramitcally without it being 4wd, which is why you are peeling out or burning out. its fine really, but when burning out gets boring and starts tearin up your tires, its gonna have to go back to 4wd. if you dont care, you can remove the pulley shaft, the front 2 pulleys, and the front belt, just to lost some weight.

Y2kGTP-no its allright, wont rub, trust me. plus, the air filter is so close to the silver arm, that it would rub if you lifted it any.

anyway, here's step 1 of my ongoing project:Blue aluminum nuts and PowerTune head from the 2.5r. the head is a bit bigger it seems, which means better cooling. i need it, when i took the stock head off, i had black marks on my piston. i was runnin too lean a few days ago. more parts to come.

http://x2.putfile.com/7/18717321067.jpg

[JoshsTL01]

well i had to put my ez-start back on cuz the pull start is not workin well. my engine still wont start, but i think its just not tuned. im tired of pullin that damn thing. seems like i spend more time doin that than drivin the damn thing. the 4 ounces isnt worth it for parkin lot racing.

[T-maxx 4eva]

Whats up josh ( fellow jato driver ) I am thinking of getting one of these. I am going to try to get a job at my lhs so i can get a discount. I just got my jato and in about 6 months will probably get a 4tec.

Convince me :)

60mph+...done :cool:

[T-maxx 4eva]

lol ya i heard about that speed that traxxas brags about. If i got one though i would tryto fit the schuamacher ( sp? ) fusion 3 speed in it, to make it go at least 70. My friend has a 800 yard smooth tar paved road going to his house ( hes rich, his dad wons 3 islands in tahiti with resosrts on them ) and he has a nitro 4 tec and i want to get one and woop his. Is the 3 speed possible to put in? If not, is it possible to put a .21 in it?

[Y2KGTP]

in about 6 months will probably get a 4tec.

Convince me :)
Doug

I'm just not happy with mine....the only nice thing is the EZ-start, the reason I got it for my son. I'm trying to clean up the wiring, and location of the radio equipment, as it seems like an afterthought on where the receiver & battery go on the chassis.

The only reason it is claimed 60mph + is as it is geared really tall, and not set up for a nice road track, more for high speed runs.....my NTC3 with the stock AE .15 engine is still faster......and handles better as well

[T-maxx 4eva]

yeah i was either going to get the NTC3 rtr plus or this. The rtr plus is only 9 bux more, so im not worried about [paying all that extra, plus on all items over 300 tower takes off 30 so it will be like 280 + tax and shipiing, so it will be like 309 lol.

If you have a choise, I would get the NTC3, over the 4-Tec.....I have both, and the NTC3 is just a better designed car, with a heiftier amount of aftermarket support for the vehicle.....not much is made at all for the 4-Tec, that I could find....

[JoshsTL01]

4-tec has alot of good cf stuff straight from traxxas, and a lot of aluminum parts from others. as a track car, the TC3 is better, but just as a basher, id go with the 4-tec. if you were to race someone in a parkin lot in a drag, youd kill em with a 4-tec.

Any suggestions on improvement of the breaking? My kids just comes to a slow stop.....

And it needs a shorter gearing....takes a looong time to get up to speed...

i had a N4tec many moons ago, i found by replacing the brake disc to the graphite one helps a bit. also adjust the servo linkage... good luck

[skylineTT]

nitr 4-tec plus O.S. .18TZ equals over 80 mph! its ballistic. my friend just got his tz and a new spur and cb combo. radared the beast at 81.2 mph. i cant even control it. its quite difficult but he drives it well

what type of radar system did ya'll use???

[Duster_360]

skylineTT - I've got 2 4-Tecs, a Pro I used to race (long time ago) and a RTR which I've run just twice after finishing breakin. Was the 18TZ a dropin or was there a lot of work required?

Is your 4-Tec an RTR, does that one use a SG type crank or a threaded crank? Guess its has to be the same as the engine in the Tmaxx so thats the SG crank. I've never looked at my RTR much. Then the 18TZ you would use is the 18TZ(P), right? That's so cool. They have just put a nice, new asphalt parking lot down at the high school 2 blocks over and I was thinking of getting these back out for a drive. What tires were you running - how did they hold up?? Using a starter box, right?? What a great idea - I was going to put my spare FR18 in mine, but this is a way better idea! Thanks!

[Duster_360]

Think I've answered my own question. I did not realize the 2.5s in the 4-Tec are short cranks or threaded type crankshafts. Now I know which TZ would be the easist to swap. What did you do for a header and a tuned pipe??

[NesikaChad]

I just recently became interested in all this stuff. I've bought two cars. A Jato and a 4 tec.
Here are some ideas, would appreciate your input.
I work in a manufacturing facility with some pretty good resources. This weekend I constructed a laminate 6061 alloy/carbon fiber chassis for my 4 tec. Completely CNC machined.
Came out pretty decent. A few little things I'm going to change on the next one. The chassis measures .094" (Stock Traxxas 4 tec alloy chassis is .125") in thickness and I achieved a relatively conservative 30% increase in over all rigidity.
My test methods were a bit crude, but I think the data is ball park accurate. The part is lighter as well.
So, the next step: Reconstruction of all the polycarbonate upper chassis/suspension pieces in 6061 aluminum (perhaps titanium after I proof out all the code) and see what I get from that. Ultimately, I want the car to be "tight" no more slop in the steering/suspension, etc.
A friend and I are considering opening a shop that specializes in this sort of thing. Just wondering what folks like you would think.
Your comments would be appreciated greatly.


Thanks

[NesikaChad]

Josh,

Unfortunately, this morning around 3 am I wound up in the ER with a kidney stone. I'm so drugged up right now I don't dare drive anywhere. I should be up and about tomorrow and I'll make an effort to get some photos of this stuff.

Thanks for your interest.
