Yokomo GT-4 Nitro Touring car (all versions)

[PhillyNitro]

dont no one like these?

[mouses]

I do, I used to drive a Mugen and changed to the Yok GT4w. It is a superb car easy to drive, setup etc.

It seems to be ignored now, When it came out it had similar attention to the NTC3 now. It won nearly everything last year.

Pro Touring cars all seem very similar in performance nowadays. Which ever is the newest is usually the flavour of the month, the best touring car ever.

two penny's worth.

[PhillyNitro]

Thanks for the info cause Im thinking of picking the gt4 rtr up soon:D

[mouses]

If you can afford it get the GT4 pro. It will have all the upgrades you will ever need. A good place for info is the forum on www.yokomousa.com .

Enjoy!

[davebirt]

Who the heck is he to say delete this thread? Shouldnt ppl that have these cars or are thinking of getting one have a place to talk about it?
My guess is he is just an AE troll and should be ignored.

ANYWAY. I am thinking of picking on of these things up, my only concern is the availability of parts. I am also looking at the RS4 3 SS, but having seen both in action, I can definately say the gt4 is faster and easier to drive(MUCH faster). BUT I am afraid I wont be able to easily get replacement or hop up parts.
Anyone know of any good places online to get parts?

[TC3Kamikaze]

Speedtechrc has most the parts for the GT-4.

[micro_man]

What is the difference between the gt4 w and the regular gt4? what is the difference between the gt4 r and the gt4 w? lmk

thanks

BTW i am thinking of selling myrs4 3 ss to get the gt4 here is a link to some pics and stuff....email me for info if you are interested.

[TC3Kamikaze]

The gt4 w is the 200mm version of the gt4. The gt4 r has a lola or gtp body, oneway, lower mounts, lower shock towers and a few more things. Check out yokomousa for more on them.

[teamlosi 4 life]

does tower hobbies carry parts for this car?? the only thing holding me back is part availability. is it easy to work on??

[spawn]

Guys, I am planning to get the RTR, any problems with the 2 speed, read that it breaks....

[TC3Kamikaze]

Tower has some things for it. I'd go with speedtechrc for the price and supply. I haven't heard of anything wrong with the rtr. Check with the guys at yokomousa.

[Matlock]

I'm looking at the GT-4 Pro or a NTC3. I was going to get the NTC3 for sure, but tonight I started searching a little more and found this nice little car. It sounds like its the real deal. Plenty of big wins from pro's, plus I wouldn't be like everyone else at the track(BIG plus:D). I know the inn's and out's of nitro, so I will be able to work on the car and stuff fine, but I have never really setup a car before. Is it going to be hard to set this thing up? Will it do very good on a short tight parking lot track? It will have the power to move it fine(MT12, X12 or RS12 S3 are what I am looking at). But what does it handle like? Can anyone compare it that has a NTC3 also? And what are the biggest pro's & con's of this car? And what are the spare parts to keep on hand at all times? Thanks for all of your help guys!

[Saboteur]

I met up with some guys at the park last weekend who each had a yok gt4 pro. One had an mt12 and the other had an rb concepts 5port. Also both were running foam tires. The speed was insane and they didnt even hit 2nd gear ( I believe they both locked it out). I was racing my neo tnt with the m16. Take of speed seemed a little slow but when it got on that pipe it took off.:) But still Id like to get an fr12/fr15 and then come back and race those too and see how I hold up. Another reason as to why the cars have such great top end speed besides the foams and high powered engines is that on first gear its like 6.0 and 2nd gear is like 4.37 or so. My cars gearing is 7.02:1 on 1st, and 5.38:1 on 2nd. Time I get a faster engine some tires and other stuff to beat these guys. But seriously its a great car and Id recommend it to anyone who'd like a car with performance. But, I like my neo tnt as well, especially since it came with the centax clutch. I plan to add the pivot ball suspension to it as well at the other goodies I'm gonna get to race. :cool:

[NuG050]

I like it and wouldn't trade it for anything else! I have the GT4RTR version and it's pretty dang fast out of the box! I doubt anything else compares to it so far! At least in RTR form...^_^

[MitchellXXX]

i bought one about 1 week and a half ago and definately for out of the box fun and pretty damn good handling it's on top my tc3 nitro will be here in a week and i'll beable to see which is better. i think it would be nice for the yokomo to come out with an updated version and shaft driven tho.

[Saboteur]

What would be nice if the pro version came with a graphite upper deck and some other goodies. But still, all versions of them are great cars to race.:)

Nice pictures im glad to see someone finally posted pics of their GT-4

[Archerboi]

I was taking a look at this car. Its pretty good with all the features that it has. I was wondering about the radio. What version does the RTR car have? I know its a Airtronics Blazer, but is it the sport, or the one with the dual sub trims and all. Thanks.

[Trevor280z]

hey. i just started to get into r/c onroad racing. i first wanted a rs4 type 3 SS. but i was told that they are more for parking lot racing. so now im looking at the gt4 RTR. everyone said they are basically the only real "race" car that comes RTR..beside the ntc3 which i dont like. i have a spare futaba radio so i was going to switch out radios. is this car a good racing one or just another street basher? thanks

[Dan H]

The GT4 has been the 2000 and 2001 ROAR national champion. I think that says a lot. ;)

The GT4 RTR can definitely be made to race easily unlike the HPI which will need a lot more money and tuning.

[RCFUN2]

made a floating body mount for the Yok Gt4. I will try to post pictures, if they don't show e-mail me for them and for imformation to RCFUN2@aol.com.

Thanls,

[RCFUN2]

This is a body i made.

[RCFUN2]

This a lower front shock tower that I made

[Saboteur]

Dan, the only reason why it wont the nationals, is because of the person who were driving it. Its all about driving skills man, also a little luck. Both the yokomo and the ntc3 are great touring cars. But if you are looking for the fastest in rtr form, the yokomo is the one to get. It tops out at about 60mph, while the AE rtr is about 40mph. But still you can swap the stock engines for more powerful engines later on. So to save money, I suggest you get the kit form and pick out your own engine and use your radio if you have one. Great pics rcfun.

[RCFUN2]

All the parts I make are for sale. E-mail me for imfo.

[Dan H]

Yeah, at that time, Barry Baker and Chris Tosolini did some impressive driving. The NTC3 is also a nice car as well. Almost bought one myself.

I've driven the RTR3 (only difference with SS is faster engine and 2 speed) and even with some decent slicks, the RTR3 is still squirly and doesn't have a direct feel as the other cars. I can't imagine with the SS since its faster, I would only expect that it will be harder to control.

[DUMMIECHASER]

hey was up
hey im planning on getting a gt4 next week .how long can one 10% bottle of fuel last on run time??

[Tabushi]

It all depends on your practice time ... right now im very LOW on run time so a galon of fuel last for me 1.5 months ... but on very good practice season i usually get 3 weeks on one galon ...

hope this help...

Hi I have a nice Yokomo GT4 pro and it is great it has a MT12 turbo and alot more click on the link http://www.geocities.com/rcwannabe2003/temporarypreviewfile.html?1039408075460

[cHckbOY5]

hi, i need help!!! i was thinkin of gettin the gt4 rtr... but after awhile, im now thikin of gettin a gt4 pro or S. are these kits too hard for newbies? it will be my first nitro car, i previously ran a tc3 but never really got serious with it

[DUMMIECHASER]

whats up
hey guys i have the gt4 rtr finally but i have got one shock broken,the front wheel of all because of a stupid driver who didnt see it in the street.well guys i went to theis new hobbie store and i was talking to the guy about my car.he said my gta rtr could not really hit 60mph he said the box was just lying ,he said the would not put that much power in a rtr.HE TOLD me the only true car that can hit 6o or 80mph would me getting a serpent and building it myselfi really am comfused i dont know if he is rite or not.guys does it really hit 60 has anyone ever put a speedometer next to it.guys i dont know what to believe.has anyone proven that goes 60 instead of 40mph please help me up:confused:

[cHckbOY5]

help, what should i buy?

[DUMMIECHASER]

would someone please answer my question

[Dan H]

cHckbOY5, the Yokomo kits are straightforward and easy to build. But with the GT4 RTR, Pro or S version, will require basic knowledge of camber, toe, and caster and their effects. As long as you know how to adjust them to your needs, you will be fine.

DUMMIECHASER, the GT4 RTR doesn't hit 60mph. My GT4 with same exact stock gearing, MT12 and RB X12 pipe managed to hit in the mid 40's leaned out. This was with a relatively accurate radar gun. I also ran side to side with my other GT4 buddies and the stock RTR cannot keep up with an MT12. Stock gearing just doesn't allow the GT4 to hit 60mph unless if you have an 18/21 gear but with the RX .18 engine, this may be pushing it a bit. The Serpent Impulse are about the same speeds given same engine and gearing. Remember, there is no faster car but handling will be different.

If you want all top speed, get an HPI RS4 2 and put a 13/20 44/37 gear or buy a Schumacher Fusion. If you want handling, a Yokomo GT4 is the way to go.

[RCwannabe2003]

If you want a hpi i have one cheap but if i was you dont even go for them get a Yokomo hpi cars i always had problems with the engine coming off since it isnt counter sunk and stripping the gears alot also get a yokomo they are better

[cHckbOY5]

r yokomos also good for just playin aroun in parkin lots?

[Dan H]

Yes, perfectly fine for parking lots.

[cHckbOY5]

if i get the s, is dat too complicated for newbies? n wat engine should i get? i heard i shuldnt start with a race engine. do u think an airtronics mx3 would be a good enough radio?

[DUMMIECHASER]

thankx dan.so DAN I REALLY WANT MY CAR TO GO 60 SO WHAT SHOULD I DO.SHOULD I GET A NEW PIPE,NEW GEARS and what kind.p[lease help me.i was also planning on buying a serpent

[RCwannabe2003]

The Serpent sucks I hate them get a Yokomo and buy a Collari or a MT12 or a Rossi Pixiy .12 black you dont need speed to win a race so just get a Yokomo it is the best

[cHckbOY5]

anyone have the s version yet?

[Saboteur]

Serpent cars dont suck, but they are expensive. As for your statement RCwannabe it doesnt make any sense: " you dont need speed to win a race so just get the yokomo it's the best". There is no best sedan. Just compare each kit and see what other car kits have the others dont.

[Dan H]

Like I said, its not complicated as long as you know basic tuning skills. The GT4 is fairly easy to setup. Serpent Impulse is a great car as well but in comparison feels heavier (actually is heavier) than a GT4 around corners and a bit more difficult to setup because everything has to be precise. Its way more durable than a GT4 though since the parts are rock solid.

As for engines, any O.S. will be great for newbies. They're easy to break in and tune. MX3 is a fine radio as well.

A new pipe would be my first choice. The stock plastic bolt together pipe is terrible IMHO. I'm not too sure if you can 60MPH out of the stock engine but you can always try new gearing. The tallest gears Yokomo makes is 18/21 pinion gears. This will give loads more top end but low end will suffer and it may strain the engine a bit more. After the stock engine dies out, I would go for a high end O.S. or Novarossi engine. It will pull that kind of gearing with ease.

[DUMMIECHASER]

will that novarossi engine pull sixty or more.or will a serpent engine pull more.will it even fit on a gt4 kit?

[Dan H]

Serpent engines are made by Novarossi.

[cHckbOY5]

i guess no one has the s version yet... is this chassis still competative? how come it wasnt even in top ten in the worlds?

[Saboteur]

As of right now, I dont see many people interested in the yokomo cars anymore as if it had gone outta style or something. Mainly people are eyeing the NTC3, V-one-R and V-one-RR, serpent 705, GS vision pro,etc. Yes with a novarossi engine or serpent you will be able to hit 60mph. As for the yok winning the worlds that was a while back, now other cars are stealing the show. The competition is heating up everytime and drivers are demanding more performance. Some kits they drive arent as consistent as others so they move to the better one.

[cHckbOY5]

so u think even the s version comin out is outdated?

[Saboteur]

No, just saying that nowadays its not the popular car pick. Just look at the other forums and you will notice they rarely talk about it. However you can go to www.yokomousa.com and join the forums. There are plenty of people who own gt4's there.

[cHckbOY5]

do u recommend ntc3 or mtx3?

[Saboteur]

THe MTX-3 is one hot lookin rc. :cool: However if cost is the factor for you, the NTC3 is also a great buy. It doesnt need to wear many upgrades to race. Just some basic things to get are shocks, shock oil and springs ( good to have different types to see what hooks up well at the track), engine, tuned pipe, tires, and thats about it. If you want to go all out the MTX3 is a great buy. Ton's of features and awesome performance. Both cars are great though IMO.

[cHckbOY5]

do u think the extra 50 bucks is worth it in buyin the mtx3 than the gt-4 type s? cause with that 50 bucks, i can buy a starter or sumthing lol

[Dan H]

The MTX3 is a great car but weary since it comes with a front one way diff. You'll have to use foam tires always with this setup. I think you can order extra parts for a gear diff up front but it will cost more.

[cHckbOY5]

doesnt the s spec come with the front one way too?

[DUMMIECHASER]

guys i hear the serpent veteq can hit about 80mph?well i love my gt4 and i wanna update it to hit 80mph.so do u thinkif i put a novarossi engine with other gears and do u think it will hit.guys please help

[Dan H]

cHckbOy5, yes it comes with a front one way. The GT4 Pro has front and rear gear diffs so that will be a better choice than the S version.

DUMMIECHASER, Veteq can't hit 80mph. (Maybe close to 70mph if you run a RB C5.) GT4 will never hit 80MPH. Seriously, if speed is all you're interested in, get a Schumacher Fusion, Bolink Dragster, or whatever. GT4 and Veteq were designed and engineered to go through the turns.

[DUMMIECHASER]

well since the rtr wont hit 60(like they say)what will make it hit 60mph or more.

[Dan H]

[jblaze725]

we all love the high speeds but you should focus on more than that. even if you have a car that will go 70 or 80 mph youll barely ever hit that cause that takes a long straightaway to do. not to mention it has to be smoothe and you have to be able to control your car cause any small upset to the chassis at that speed will make the car lose control and you can imagine what a 70 or 80 mph crash on a little 1/10 scale car would look like. more important than what that would look like is how it would feel to your wallet. now thata painful.

[Saboteur]

I agree. Also it would be even worse for the 1/8th drivers when they crash their cars. I remember hearing about Micheal Salven's 1/8th serpent crashing into a fence. I know I'd be pissed if that ever happened to my car. Its cool to say " Oh my car goes 70mph", but like jblaze said it will require a lot of space to hit that speed and the slightest bit of disturbance in the road will cause an accident. The guy's I have bashed with in the park both ran yokomo gt4's, one powered by an MT12 turbo and the other with an RB X12 5port. Both car's acceleration was unbelieveable and that was only on 1st gear. I'd opt for the acceleration than the top speed; atleast thats enough to give the neighborhood kids thinking the car is doing 50mph when its actually doing 40-45mph.
:D :cool:

[DUMMIECHASER]

hey guyz my car allowyz gets water on the servo or the power place next to the on/off button.how can i cover my servo so the water wont get on it.

[Saboteur]

Dude, why do you keep getting water in your servos? Onroad cars shouldnt be driven in wet areas anyway. :) :D

[DUMMIECHASER]

because there are lil puddles because of the snow.well see ya

[Saboteur]

Well I think I mention this before. Try using silicone to seal up the the parts of the servo where its screwed on and where the 3 wires go into it.

[DUMMIECHASER]

guyz im so pissed(mind my lang)this car has the same prob with the controler again.it seems like it wont receive the radio sigs.i send it.today it ran out of control and hit a wall at around 50 allmost everything got messed up .y is this car so expensive to take car off.what should i do.should i buy new servos or something.i really love my car it works when it likes too but when it doesnt it ends up making me pay 100 everytime i get it fixed.:mad:

[Saboteur]

What radio are you using? Are the TX and RX batteries fully charged or fresh (if using AA batts)? A rx battery pack will work well and will last longer than AA as well as giving your servos maximum power. If you using AM them switch to FM. There a lots of decent Fm radios that arent cheap. I've been using my AM though for quite a while (Futaba 2pc) and I havent had a glitch. Well most of the cars especially the Serpents are expensive and so are its parts. The NTC3 parts though are cheap, as well as my Neo. :)

[DUMMIECHASER]

im using the stock rtr radio.ima have to buy stronger one thank you

[Saboteur]

A cheap but nice radio to get is the Airtronics MX-3. Its loaded with lots of features like 5 model memory, 3channel(great for tmaxx), ATV, etc. You can even turn the sound off..LOL.:D JR has the Xr3I or something like that for around $170. It only has 4 model memory but one of them has 30channels avaliable and you wont need to use crystals anymore. Just dial into your channel.

[DUMMIECHASER]

coo thanx dude.do u go to the track and race with your gt4?

[Saboteur]

BTW is the XS3 not XR3. I dont have a gt4, I own a Neo TNT. I'm going to get a VoneR kit though later on.

[tl01boi]

i have a super nitro with 2 speed tranny 3 sets of wheels 2 bodies newer heat sink head that was dipped in chrome and tuned exhaust that was dipped in chrome i also have 1 extra tuned exhaust for trade KhMyAzNbOi@yahoo.com

You should post this in the B/S/T Forum.:)

[Allen T]

Does anyone have trouble with the belts when running on parking lots, etc? (from pebbles and stuff) I've never had a belt driven car, but I like the GT4 RTR.

Thanks!

Allen T

[Saboteur]

Some go for shaft driven touring cars because debris will have no effect on their drivetrain. For me driving a belt driven car in a debris littered area is no problem. Most of the best cars out there are belt driven. The Yok gt4 rtr is pretty good though it doesnt hit 60mph. Great car to race, bash, etc. Join the yokomo forums at www.yokomousa.com to meet other gt4 fans there. I havent seen anyone reply to this forum in ages..LOL.

I too am considering my first "belted" car. Anyone else have opinions on the amount of "abuse" their belt driven car can take?

-Puma

[Dan H]

It depends on the surface you are running on. On dirty surface with pebbles, the inner pulley can strip easy and the belts don't take as much abuse like the belts that come on Serpent or Kyosho for example. (Only good thing is belts are cheap.)

For the most part, the GT4 likes clean surfaces.

[I Stang U]

I bought my gt4 right before a big race here locally... tuned it out and dropped in on the track... I was unable to finish a race in my hpi cause if I nicked a wall or even looked at it wrong it would slide out and brake...first time I even drove the yoke I got 4th our of 20 in the a-main..... now I have upgraded to a MT-12 and I can't wait to race it Saturday :D

[filipinoguy]

[TopKatz]

Hello everyone!!!

I nead a little help. My friend just got a gt4-s type kit. For thouse unaware of the s kit, it is basicaly a "W" with a centrex, solid or gear diff rear, front one way, and a 2-shoe 2speed. It also has the aluminum shock towers.

Anyways, he has the kit all built up, but we are having some trouble with the setup. This car is basicaly a high end basher. We mostly run rubber tires in parking lots. Im looking for some set-up ideas to help get rid of his nasty over stear on the car.

Right now he is 5mm ride hight, gear diff in the rear with 30,000 wt silicon oil in the diff. Curently the car handles better with the foams on then with the rubber tires...

If anyone ahs a good parking lot setup with shock setings(spacer numbers, and hole placment), tire numbers, toe out, and ride hight I would so apreciate it!!

[Racer-Kid]

It oversteer because it has a one way. Try practicing using a one way and your laptimes will be lower. :)

[Saboteur]

Yeah, when using a oneway the acceleration does increase, but the wheels free spin in the turns and you do loose the front braking. Like Racer-Kid said it will take some time getting use to. You may have to make some adjustments on your ride such as camber, or toe in-out, as well as radio adjustments.

[I Stang U]

I love this thing... I really want to get the type s but I will need to sell my vission before I can get the new yoke

but anyway here is a Pic (http://www.hobbytowndallas.com/modules/mx_album/album_view.php?id=56)

[Racer-Kid]

Very nice car I Stang U!! What kind of engine is that? mr12 or mt12? :rolleyes: :)

[I Stang U]

mt12


I have a mr12 for a new one as soon as I sell my visission....

[Saboteur]

Awesome ride. :)

[Saboteur]

BTW, what brand of exhaust pipe is that?

[I Stang U]

not sure it is from over seas and is fully adjustable for torque or highend :D

[Saboteur]

LOL. Kinda looks like that Ofna RE pipe set. Or is the ofna pipe a bit wider. I'd really want to bash my nitro for the Summer or so, but not really spending anything big since I'm saving for a real car. *sigh* :(

[I Stang U]

yeah the sport is expensive.... but damn it is fun...

[Saboteur]

What I did notice is that the nitro's in the 1st vid didnt sound as loud as others or mind. Some pipes are good at keeping down the noise level. Like I said before, the weather now really sux for running a nitro due to the rapid changes. An esc and mod motor for my project tamiya, http://www.radiocontrolzone.com/forums/showthread.php?s=&threadid=125854&highlight=Project+Tamiya

will be all that I want for now. To bad :(

[filipinoguy]

Anyone hear about the new GT-4 RTR2.

[I Stang U]

well I have heard about the new kit but not the RTR....

the new kit is just like the one that one many of the national and world events I believe.... type S

and I really dislike that .18 they put on there... it doesn't last long at all....

I love the car.... the new pro type s kit comes with tons of aluminum and upgrades.... that looks just like the current rtr..

Great pics Stang. Didnt know the YOk cars now had an upper deck that centers the fuel tank. I dont think the gt rtrII has the same .18 but some new RE engine with p/s. Its claimed to be a lot better.

[I Stang U]

I got the upper deck from peguin RC instructions really sucked... but over all it is well designed... and really cheap :D

[Saboteur]

lol. How much was it? Id really like to find that center fuel tank upgrade for my NEO. Otherwise see what other upper deck (probably from the NEO ATTACk 235mm) can fit. Speaking of NEO, my TNT is back together and ready to be driven. Most definately I'd check a faster and race legal .12 to slap in my ride. :cool: BTW what happened to the roll bar? :confused:

[I Stang U]

I haven't put it back on.... the upper deck was about 38 bucks...


do a search for peguin RC and you will see what they have..

Cool. I'll see what they got. BTW whats up with the pipe? Is that a AE tuned blue pipe? How does it run? Thought you would have gone for a novarossi, THS or a RB pipe to match up with the MT12..lol.:D

[I Stang U]

well it is fully adjustable so I can change it at any time... for low or highend tuning depending on the track.... I haven't seen any others that you can tune on the fly :D

[Saboteur]

Wow! Thats nifty. Just how do you tune it? Also how much was it? I'd surely like some new gear for my NEO. :) BTW where was that link with those video's? I want to D/L the other vids to see more nitro sedan racing as I've been away from it for a while. :(

[I Stang U]

you just screw an part on the inside of the pipe and I bought it used so I am not sure where to find them...

racing videos can be found at www.hobbytowndallas.com on the main page....

[Saboteur]

Cool. Not the best of looks but hey if it performs great, thats what counts. Thnx for the link.

[I Stang U]

it is the hobbytown colors....

what do you not like about it....

[Saboteur]

Really nothing wrong with it. I'll check it out. Oh yeah, whos car is that slammin into the board where the camera is on the 2nd vid? OUCH!..did he loose control or had a brain freeze? :p :D

[I Stang U]

he got our of the vht line and lost traction :D

[Saboteur]

LOL. Man gotta stay where the track has the traction additive layed down. I wish I could tear up some lots or the sidewalks here but its gonna be raining on/off for a long time.:(

[mjime714]

sup guys. I got a story for those of you who dont think the GT4 can hit 60 out of the box. I know you guys dont know me so believe what you want.

I run a GT4 with an RB X12t 5 port. I geared it with the gold pinions for acceleration. My friends I bash with and I were clocking speeds with our police issue radar gun. At 10 passes I was running at an average of 57mph with a top speed of 63. So with that said, a guy came out with a brand new RTR that he just finished breaking in. He had no idea what to do with the car, how to tune, power making hop ups etc... anyway, I tuned the car for him and it was running very good. We lined up for a drag race with the radar there to clock the winners pass. I jumped off the line and took him, but at the top end the RTR was matching my speed to say the least. Mind you, he was geared for more top speed than mine (Stock RTR blue pinions). My run was clocked at 59mph. He must have been going around the same. Believe what you want. I guess it was an ideal day to run because all the cars that were out there were running great.

[rc man37689]

is the gt-4 rtr 2 a lot better then gt-4?

[mjime714]

Im not sure I get your question. Are you compairing the GT4 RTR with the GT4 RTR 2? The difference is a rear exhaust .28 mill, metal exhaust, and the new y pattern wheels with the bbs style wheels. Compaired to the OG rtr that has a cheap plastic exhaust, side exhaust engine and the worst wheels in the world... yeah I would say its a lot better.

[rc man37689]

you mean .18 not .28 lol type SLOWER!!!!

[mjime714]

NAW, I really mean .28. :D Oops sorry. Yeah, I do mean .18. Mah Bad.

[save1992]

is this car worth buying or should i get a ntc3 or ld3 can this car run with the 4tec

[Saboteur]

The nitro 4tec is fast and can easily hit speeds of 60mph+, but the handling isnt that great. Some swaybars are a very worthy upgrade for it. If you want to race in the future check the GT RTR 2. That will get you rolling out of the box and onto the track for some fun. If you have the cash, then you can try the NTC3 kit or the LD3 pro. Whats cool about the LD3 Pro is that it comes with a partially painted body so you can paint the rest what ever color ya want. Also I believe its cheaper so you can save some $$ for xtra accessories needed. Remember go with what ever your LHS stocks the most parts for.

[natu]

can anybody give me some advice?

[natu]

i am a beginner and i don't know if i should buy an rtr or a kit as i don't have alot of experience can any body help me? :(

[Saboteur]

An RTR is good, however with a kit you will learn how to put stuff together along the way. It may take hrs or so but its worth it. I built a stock TL-01 from scratch (was my first rc) but it wasnt hard at all since it was quite an easy kit. Just remember the Yok kit requires an engine and radio gear. If you get the rtr your basically set and ready to bash around at the track or lot. My first nitro onroad came 80% assembled however disassembling wasnt a prob as it was quite easy to replace things. Go for the RTR then if you want. Besides when you upgrade to a new engine, you'd have 2; one to race, one to bash. ;)

[natu]

when you buy a kit do u have a manual with details of part and what they are cause when some people mention parts of there cars i would not know what they are talking about. i am not sure yet.

i was interested in a yokomo car because in malta there aren't many agents of rc cars and the only type of cars i found are " tamiya, yokomo and shumacher" . both yokomo and shumacher are from the same agent and the agent owns a club and a track.

from scumacjer website i wasn't very impressed on what they have to offer . i found out that the electric cars are much cheaper but i don't know what kind of speed they are capable of achieving.

can anyone give me a hint on what speeds can electric cars get?

thanks.

I guess so.

Bummer, I see a lot of the RTR cars on eBay at $299NIB. I guess it's not a good deal.

I think that the ebay RTR thing its just people buying and selling kit ... for money ...

Why ?, simple, the RTR from Yokomo its the best out there on market ... maybe a little high priced but its a competition chassis !!!

Hi all. I just purchased a new Yokomo GT-4 2 RTR. Can anyone tell me what the difference is from the GT-4 1? I had an offer to buy this car brand new for $299.00. I think I got a good deal. Is there anything special that I should know about this car? I have a CEN CT4-S, and I think this is going to be a good addition to my collection.

Any thoughts?

Thanks for any input.

[rcnitropro1]

not much difference. glued tires and the tires themselves and a couple other minor changes. but yeah, it was a decent deal.

[saxtech]

I have a GT-4 RTR (first version with .18 side exhaust) I have gone through well over 10 tanks of fuel so I am pretty sure it is broken now. But when I tune it, I can get it to run great but the temps are too high with the body on (around 280) and not much better with the body off. I cut out the side windows on the Porche body and still no better. I am using 20% fuel with a OS-8 plug. When I richen the single needle adjustment screw, it cools off a little but it doesn't run as good. (Kind of sluggish and toomuch smoke)

I don't know what else to do other than get an aftermarket big head for it.

Is this a common problem with the Yokomo .18 engines ?

Should I get a 2 needle carburetor ? Willl a 2 needle carb make any difference ?

If so, how much are they and send any helpful links. I am ready to put this car away and use my XTM's if I can't fix it before I burn it up. My car is new (only 2 weeks old) and maybe Yokomo can send me something to help out ?
Please help ?

im a nitro starter i need help on how to tune the engine up and breaking the engine in. people help please. :confused:

Pretty dang fast car you just ordered. :)

It will come with basic instructions for where to start with needle settings, most likely.

Go here to read the basics about nitro engines and breaking them in and tuning.

http://nitrohouse.com/engine_breakin.htm

[saxtech]

I have the GT-4 RTR (first version) with the Porsche body. This car moves pretty fast once it gets going (slow acceleration and low bottom end torque)

But when it is moving fast, it seems to not grab the road at all and slides all over the place with every action taken on the transmitter.

The steering seems way to subtle as even just the tiniest of steering movement causes the car to jump to the other side of the street if it doesn't spin out.

Whats going on ?

Do I need a new (better) radio to adjust the steering sensitivity ?
Do I need better tires for street racing ?

My other cars don't do this !

[Gyro Gearloose]

Hi saxtech

Has it always been so touchy? Maybe you can reduce the steering a bit by moving in one hole on the servo?

If your other cars are 1/10 touring cars/sedans, try the tires from one of them, almost all 1/10 TC car wheels are the same hub.

[Dan H]

Get better tires and check alignment. I know that some of the first batch of RTR's from Yok didn't have the alignment setup correctly from what I have seen. Plus, although the stock tires grip decently at first, once they're worn in a bit, its like driving on ice. Get some better gripping tires.

I have the same problem. Is there anything that can be done to lower the temp? 280 is WAY too hot, I'm sure. I can get it down to about 240, but it runs very poorly. What does everyone think about this?

[saxtech]

Rubber is usually your best bet for street/parking lot running.

Really ? You mean rubber is better than foam tires ?
Please tell me brand and
compound and
type and
size to get for my GT-4

[gasser]

I was told by a very reliable source, that if you are using 20% nitro, you could go up to 25% nitro and run noticeable cooler. Is this true? I always thought if you increase the nitro content, you would increase the engine temp as well.
What do you think?

Thanks!

[yokodude2]

God i love my GT-4w but up grades are so cost too much parts arnt much better

[Gyro Gearloose]

Saxtech,

All I can tell you is to see what's available at the LHS, probably HPI belted radials, or maybe some Venom hypers or something. Foams WILL work, they just can't take a beating on the rougher surfaces like some rubber tires. All 1/10 sedan/TC wheels are the same hex hub(except Mugen, I think) and all about the same diameter.

[Gyro Gearloose]

Saxtech,

Here is a discussion about a couple of tires(brand, compound), maybe it will help you decide.

hi all,
i just purchased a yoko gt4-2 rtr and i am wondering why i dont see a low-speed needle on the yoko motor carb?(i have the rotary carb).
all thats there is a hi-speed needle and a throttle idle set screw..
and what is the hi-speed needle setting after break-in? and temps?
also has anyone had problems with the recoil not winding back in,when pulling my rope sometimes it stays out and i have to tap on the plastic housing for iy to wind back in.
thanks all.

[jerseyevo]

i guess this is not the place for help.

[Dan H]

No low speed needle because its easier for newcomers to the hobby to not mess up and cheaper too. An OS .12/.15 CV carb is a direct fit and improves power a lot. Not sure about the other questions though since I don't have that engine.

Hey guys. i have decided on two cars NTC3 vs. GT-4 rtr 2, im not new to nitro nad understand the ins and outs of nitro cars. I want to get my self a nice on-road car, and these two seem to be the cheapest, and well built cars i can find.

[jerseyevo]

i have the yoko gt4 rtr 2 and love it but it only has a 1 needle carb on it which i replaced.
and more parts are available for the ntc3 than the yoko.
you can also look into the ofna ld3 rtr which is almost identiacal to the tc3 but cheaper and has more included goodies.
i also have the ld3 and love it as well,
i dont have the ntc3 so i cant comment on it.

why is the LD3 so damn cheap. it looks so nice and contians parts that should make the price tag much larger.

after comparing different rtr kits the ld3 rtr was my choice and i am happy with it.

parts are a P.I.T.A to find locally. every shop ive gone too ive gotten the oo we'll order them for you this and that. i broke down and ordered from sheldons hobbies on the net.

its my first outing with this yoke and im impressed so much easier to tear down then my r40. would be better if parts were easier to find. this is one of the instances were associated and hpi are better. the parts are much easier to find. bottom line is go with what you can find parts support for locally and on the net.

get some aftermarket belted tires. as with any rtr touring car, the tires will expand at high speeds and that is a bad thing for on road cars. when the tires expand, they can't get much traction on the road and become twitchy.

and as for engine, i had a duratrax torq .12 in mine and it had tons of power. its a cheap to get mill and it enabled me to drift on command. and it was easy to tune.....

[YR4Dude]

dbl post

[YR4Dude]

trpl post whoops!

[YR4Dude]

I've been looking at the last few posts and perhaps I can answer a few questions in hopes of keeping this thread alive.

I currently have two GT4s myself. Love to work on them and love the way they run. I consider the GT4 to be very reliable both in function and most of all in handling. For those of you who are beginners, I can tell you that the GT4 is a very forgiving car. It isn't all that twitchy, very stable around corners and is fun to drive.

On the subject of parts, yes it is hard to find a LHS that carry's Yok parts but if you are fortunate to have a shop that specializes in race parts for rc cars, chances are they will have Yok parts for the GT4.( I'm talking about the ones that sells RC car stuff only not the ones with the airplanes and the trains and the plastics and crafts and school supplies and the etc, etc; if you're shopping there you are shopping at the wrong places) Otherwise you can shop on the Internet.(We're all here aren't we????) However my problem is with Yokomo is upgrade parts, which would cost me almost the price of buying another whole car and that's just for three things, a centax, a clutch style 2-speed and the newer hard coated shocks.

Okay enough of that, as to some of the questions:

What carb can I use on the Yokomo 18?
Any OS carb will fit. Someone found a Duratrax carb that will fit. Duratrax is cheaper than OS. So OS owners take note!

Whats a good engine for the Yokomo?
Depends on your budget. This is a car that can handling anything including some the high priced hand modified race motors. I would say, if you have a starter box, any Novarossi, Sirio, Rossi, OS, RB, STS, competition 3-port .12 with turbo plug.. If you don't have a starter box and need one with a pull start. To race legally would be any Novarossi side exhaust .12 with a pull start and slide carb. If you are bashing, the Yok .18 pullstart rear exhaust from thr RTR II or the new O.S. .18 or XTM .18 with pull start.

How do I adjust my steering, my car seems to go all over the place and spins out?You need to adjust your caster. On the front upper arm there are clips. Remove the clips on the upper arm hinge pin and slide the upper are towards the back. Then fill the gap in front on the hinge pin with the clps. This should slow down your steering. Another way would be on your radio by reducing your dual rate steering (if equipped)

Heres something for all you to consider who are looking at this site. You are probably wondering about the GT4 either because of a special on the RTR II at some shop or site or something you say on E-bay. READ THIS CAREFULLY!! The RTRs are not the same as the regular GT4. If you are a beginner stay away from the GT4-R with the swoopy can-am or gtp body. All beginners should get the RTR. WHY?????? Because the RTRs use a locked axle for the front with a loose diff in the rear. This makes it easy to drive. If you have a regular GT4 with front and rear diffs and want more control and stability on tight tracks, you may want to try this set-up as well with the locked diff in the front.

One more important thing for those buying GT4s and considering motors for them. Pull start engines do no fit the regular GT4 or GT4-R

Pull starts only fit the RTR chassis!!!

I could go on about more things but thats it for now. I'll check in again to post more.

[ghettler]

So you are saying as for the caster....is to move all the clips to the forward position? That would be both 2.6's and one 1.3?
I tweaked my gt on a board and still have trouble pushing in the turns. It has the locked front and I thought about putting some brake into the idle to slow it down in turns. This brake thing works well with my NTC3 but for some reason with the locked front or whatever, it does not seem to work as good.

Any thoughts?

[KronicRacer]

try giving it more positive toe \ / 1 degree or so negative toe will take the steering away.

[ghettler]

I'll give that a shot, it is set at 0 right now. What are your thoughts on some brake at idle?

[KronicRacer]

that depends on what your doing and whats happening..... i cant give reliable information on the motor tune with out having the car present. so heres some advice: :)

is the car rolling by its self while in idle. this usually happens when the motor is cold.

if its still rolling by itsself after its been running for a while the engine tune might be off just a little generally too rich. and you need to check temps and mix settings.

another potential issue is that the weather has a great effect on the nitro motor. tune according to the weather if you havent done so already.

another thing could be that the the pads are worn.....then again the pads should have nothing to do with the idle. actually the entire drive train should be free rolling. adding brake to the car while idleing will add drag to the motor which is not good (it can be done) its just not recommended due to the shortening of engine life.

**also it shortens the life of the clutch.

[YR4Dude]

Adding brake at idle is nothing new. Its called Drag Brake and many racers use it to help their driving. Even Brian Kinwald.

As to the braking at idle dragging the motor, that would only happen if your clutch is constantly engaged (doubtful). Nevertheless the clutch should always be disengaged when braking or at idle.

If you are having trouble turning, it could be many factors. Having 1 degree of toe in helps but it makes your car turn in sooner.

I would say the best way to tune your car is to check if everything is level. Also, because it is ball suspension, you need to check that the left side hubs are the same distance from the center as the right side hubs. This is a common mistake on ball suspensions because when you're adjusting rear toe or front camber, you can overdoo it and affect the track width of the car.

So if you got your car all aligned then start by making small adjustments in the suspension to make it steer. This can be done by softening the front suspension by reducing the spring tension from removing spring clips. Do this gradually but keep in mind about front ride height. If you made it so soft that there is no longer any front ride height then its time to do something else to get more steering.

That other method is caster. Using the clips to adjust spacing, gradually adjust the front upper arm to move forward. As it moves forward, you reduce caster and gain steering response.

Keep in mind that tuning is a balancing game of adjustments. You may want to combine both adjustments in caster and front spring tension to get the steering necessary for your kind of driving. Give that a try and see how it works out..

Also lastly a good body also helps a lot. Try using a Stratus 2.0, Alfa Romeo or Mazda 6 body.

[ghettler]

Thank You YR4Dude, it is good to see help from all of you guys now. I am going to try these things you all mentioned and get back with you to let you know what the outcome was.

Again, keep the thread alive...this Yokomo GT4 is a pretty nice car but people need help from time to time and those little tricks and tips are always nice. :-)

[Saboteur]

With more part support all over, more people will definately get this car. I am one of those people :). I have the R40 in the meantime though.

[YR4Dude]

The GT4 was a good car before the R40. The only advantage the R40 has is the laydown steering servo, a centered fuel tank and a centax thrown in at the kit price level. So all the GT4 needs is some updating in both design and economics. Right now the centax for the Yok is $100 ( somewhat pricey) vs one for a HPI or others at $40 -$45. Also I can easily update the GT4 in both steering and centering of the fuel tank simply by buying a graphite sheet and cutting out a new top plate. But why would I want to do that when I could pick up another car that is updated and improved in design for about $100? (Hence my new G4 C-classs)

If Yokomo wants to keep the GT4 alive, I would suggest that they should come out with a conversion kit like what Kyosho did with the V One RR to RR EVO. and include a centax or drop the price of the centax to be more reasonable. Next they should work on providing an LSD like a Kawahara negative diff or the Kyosho unit because those options don't exist for the Yokomo.

Otherwise you can start seeing this thread go dead as people start picking up other options for Nitro touring.

[frazerp]

I agree the GT-4 is getting a bit tired, but I am so heavily invested in this baby, I can't afford to get rid of it...having said that, a lot of the updates in new cars are very subjective. Adjustable roll centres, etc - you have to be pretty good to detetc a difference in that. And to be honest, the lay down servo thing - I seriously doubt it makes that big a difference to the c/g - however, I think a lay down servo would allow for better steering control - adjustable ackermann etc, which you cannot adjust with the current set up.

I have the Penguin R/C carbon deck which moves the tank to the centre - I have found that compromise to be more of a pain, as the battery is moved to the side belt side of the car, and it has a tendancy to rub on the pulley now. But it looks great !!

I would love to see someone make some alloy bulkheads for the GT-4

BTW, you do not soften suspension by removing the clips, pre-load on a spring does not affect spring rate - you need to change springs, pre-load simply affects ride height.

Yokomo USA used to have a great forum, but they closed it - they have never answered my emails as to why, and I have to say, I find it a bit odd...maybe it was because they were getting bagged so badly for not coming up with anythingnew for their GT-4 customers...

[death_rx78]

what difference will you find with the alloy bulkhead???

I agree with all of you yokomo better get a good new touring car or the other copanies will kick their butt in nitro, I have seen the prototype pics of the worlds and it looks good but I have read that they stop the development of it just after the worlds so let hope and pray for the development to continue

[Saboteur]

The Yokomo isn't that bad. Still a great car, yet pricey as well as parts and their foam tires. They should find some sponsered drivers for their team.

[frazerp]

what difference will you find with the alloy bulkhead???

An alloy bulkhead would just give the car better reliablility - the fine pitch threads yokomo use strip so easily in the plastic bulkheads. It would make sense to us alloy simply to provide reliability.

What pics do you have of the prototype replacement ???

How is the GT-4 II RTR? Is it worth picking up a used one for cheap? How does it compare to the other more popular models?
Thanks

[Saboteur]

Might as well get one used since the new ones are still being sold for same price they've been selling at for a while. IMO they are awesome cars. Seen plenty of them at the track whoop up on NTC3s and they are really durable. If you can get parts, they are great to have. Penguin, Integy, and several other companies make aftermarket parts.

[QDiddy]

Do they move out nice and fast with that rear exhaust .18 2 speed? Does it have a slide carb?
Can they do 4-Tec speeds?

I've been searching around for info on this car and it is no where near as popular as the TC3 and other r/c's of the like. Is there a reason for this or is it a diamond in the rough?

[Saboteur]

It's simply because this car was out long before the NTC3. It's an awesome car though despite it's age. It is quite fast with the .18 and 2speed. IT will get close to 60mph. The newer RE model I believe has a rotary carb. Pretty much with the increase in production and popularity the NTC3, R40, Mtx3, Kyosho V line up and FW05 are more of the interest today.

[Quinton]

I bought the used GT4 RTR II.
Where can I find some good info about it?
Thanks!

[Saboteur]

Gonna be hard, but a friend of mine still races his where he lives. Check yokomos site for more info on the car.

[Quinton]

Where is this company from and how do you pronounce their name? LOL
Can't really be any toungher then finding parts for my XTM buggy I wouldn't think. I have to order parts for it specifically from hobbypeople.

Why don't very many ppl race/run a yokomo? Parts and hop-up availability?

[Saboteur]

There's plenty companies that still make parts for the car. Since Barry Baker left the Yokomo GT$ and Chris Tosolini, the car basically died. NO factory driver so it's not being ran in any major events. Also as I said, the other cars of today increased largely in popularity. It's pronounced Yo-Ko-mo. :) Their site is www.yokomousa.com IT shouldn't be hard to find parts, but its to find someone in your area who runs it.

[KronicRacer]

locally it is difficult to find stuff for the gt4. one of the downsidess is not many people have patience waiting for stuff to be delivered.

i think its an awsome car from the short time i got to work with it. i put ntc3 shocks on it and it was awsome.

[Quinton]

Is the yokomousa site the only place to order stock or aftermarket parts from?

I'm looking for some better front body mounts. They make CF or alloy ones?
thanks

[Saboteur]

penguinrc and several others do make parts. Try to do a search.

[Quinton]

What is a good cheap aluminum pipe to use with the GT-4? Link?
What size engine comes with the GT-4?
Thanks

[Saboteur]

sheldons hobbies may have some parts

a cheap pipe would be a ripple pipe aka paris racing pipes http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=34063&item=5971609253&rd=1&ssPageName=WDVW

ofna racing carries those pipes too too.
the last yokomo i worked on had a .18 motor on it and thats how it came out of the box.

[Quinton]

Thanks Kronic! That pipe looks pretty big compared to my stock one. Its going for cheap so far.
So do you know the difference between the GT-4 and the GT-4 II?
I know the II has a rear exhaust .18 whereas the 4 has a side exhaust .18. I assumed it was a .15 since it looks so little. Sure isn't much adjustment on the carb.
I'm going to order that fiberglass front bumper brace from Penguin since mine is broke where the body mounts screw into.
Thanks!

Dude calm down. C'mon man the site is there, it tells you EVERYTHING, and you have to browse first. :rolleyes: :p Besides, you've been here long enough. Any pipe will work no the GT4 just get something to match the engine and manifold.

[QDiddy]

Got it Sat and ran a half tank on the drive.
Ran it for one tank on Sunday and smoked a nTC3. I never did hit 2nd gear though.
Hit some PVC and broke a front castor. Dang it!!!
Time to order parts already

Thanks for the link! That's a good site for Yok parts.

[Philly's Finest]

Well I know not to many people come here but I have a sort of rolling chassis gt4w for sale. Would be a great parts car. It's missing some screws, a few parts, clutch & motor mounts. Chassis in nice condition. Shoot me an email if interested.

[Quinton]

How much? Got a pic?
quinton4@cox.net

Thanks

[Philly's Finest]

Paid $160. Not sure what I should expect to get for it.

Here's another I found of the underside. Too big for img tags. http://www.methnet.com/hosted/yok%20chassis.JPG

[Philly's Finest]

$65 shipped????

[Quinton]

I'm looking for the 2nd speed gear that will give me more top speed. Which one would this be (#of teeth)? And where can I find it?

I am also looking for a better air filter for the GT-4. I don't care for the stock one too much. If Tower carries one please link me there.
Thanks : )

[Saboteur]

Ellegi's or THS airfilters (same thing) works well. In general moer teeth on the pinion has a greater effect on the gear ratio so I'd start with that first.

[Jayweezy]

Is this car truly not worth it now? I get that a lot on other forums. When do yall think Yok will release an updated kit or anything besides another RTR?

[Quinton]

I LOVE mine!!!

[Tabushi]

I just won my Club championship with my Yokomo GT4W2L vs all other pilots runing serpents, mugens and associateds ...

[Jayweezy]

I guess I will see if I can find an old Pro or R version. I headr that some are still sitting at shops collecting dust.
