HPI RS4 3/SS/Evo forum V2.0

[tonyt]

hey guys!

I got a question: i love to build kits and was wondering if the HPI Nitro RS4 3 18ss is worth it??? any other recomendations?

Tony T.

[apollo]

i loved my kit, pretty easy to put together, just get different threadlock, more grease, different fuel tubing and a fuel filter, other than that, tis a great car

[rs4 rally boi]

ditto this car is lots of fun and you make it inot whatever you want. just look on some of the pages of this thread. you can see what is possible when it comes to modding this car.
p.s. its pretty dope stock too :D

umm....loved as...past tence???? or spelling error?

Tony T.

PS i don't think i have enough time to look at all 180 or so pages on this thread.

[apollo]

loed, spelling error, i live the 18ss because the engine (when modified) can be a serious screamer, and all the stufff on the car is the upgraded heavy duty stuff which is awesome, i have thought about taking he diffs from my RS4 and putting them in my MT2 because they will cold up to my monser modded OS, plus, the 18ss version comes with ajustable turnbuckles and a bunch of other goodies, its worth it, just take my word ont he threadlock, grease, tubing, and filter comment

im bout to go to the lhs and get a set of the pro compound x-patterns. the inserts included with the tires ,however, are garbage and make the tires wear funny. what consistancy tire insert should i use with these tires?

[apollo]

use the soft yellow 26mm inserts from hpi, i found thtat the hards are way too hard and dont let the tire conform as much as it needs to

edit: here is the link http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXTX48&P=7

[rs4 rally boi]

thanks apollo

[SVTcobra04]

svt, are you still running the stock t15, i would swap that out for the o.s. 18 cv-rx. alot of people here are running that motor and love it.

yea i am... I was actually thinking of getting that, is there anythign else i need with it? would a 2 speed tranny be a good addition?

also, anyone here run theres on the street, with far from smooth and clean road conditions and have you found any tires that work well in these conditions?

edit: also, i dunno if its a problem with these cars in general...but i cant hold the brake down for more then about 2 sec without stalling the engine...ive messed with the idle screw an all, helped a bit... but then if i set the throttle trim to much, then the car idles to high(well more like goes instead of idling) and if its at nromal idle then when i hti the brakes the carb is almsot completly closed. im nto to expeienced with these things, so maybe im missing something like a way of adjsuting it i dunno :confused: thnx

[rs4 rally boi]

a two speed would be great, i thought you have the evo which comes with one standard but i guess you have the original rtr.

i run on not so great street conditions too, you cound pick up a set of rally tires but i think they would wear to quickly on anything thats not loose dirt or gravel. personaly i run the hpi x-patterns and occasionaly slicks. stay away from foams tho cause they can chunk or fall apart on surfaces that arent realy smooth.

you might have to adjust the knob on the brake linkage. and btw when the carb is in neutral or when full brake is applied there should be about a 1mm gap when you throught the carb.

[rcbasher38]

My buddy and i are both getting 18ss's. he already got a killer deal on ebay for a new 18ss(http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=001&item=110023721997&rd=1&sspagename=STRK%3AMEWN%3AIT&rd=1) and im gonna pick up the kit tommorow at hobby people. im new to on road but not new to nitro. ive had a couple nitro trucks in the past. anything i should know before i build the kit? any tips? what are some of the first upgrades you guys reccomend? thanks.

I would pick up some thicker shock oil, the hpi diff spring kit and maybe some tires as the stock ones are like hockey pucks(hard but last) The spring kit is cheap and great for tuning the diffs

you gotta post pics when you do. looking foward to it :)

[KronicRacer]

man.......i so need to dust mine off and get it running again.

could i get a link to soemwhere online to get a 2 speed...all i see is ones for liek the R40 and stuff, also about the carb being 1mm idle...well i got it set hgiher then that now...but if i trim it back some to 1mm..then open the idle trim srcew up a little..should it compensate for it being closed more?

2 speed for the rs4

[josh222]

here is 2 speed for rs4 3
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBTB6&P=7

[SVTcobra04]

much thanks guys :)

[SVTcobra04]

ok...well i got soem money coming my way...and wanna invest it(heh..invest) it in my RS4 :) :cool:

jsut wanna know if this engine will bolt right on, like do i need mounts or anything liek that? and will this (http://rchub.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=rchub&Product_Code=E1020&Category_Code=ND) exhaust work with the new engine?
So im getting the 0.S. engine here (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGGP7&P=0)
and the 2 speed here (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBTB6&P=7)
and these aluminum hex hubs that i think are the right ones could someone clarify? hubs (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXMNY2&P=7)

Coulda anyone suggest anything else that woudl be a good idea maybe? and sorry if these questions seem stupid jsut wanna be shore im getting the right stuff :D

thnx :) :)

[josh222]

I would go with the slide carb version of that engine, i wouldn't go with that exhaust because your then forced to use the stock rear shock tower. You can never upgrade it to the graphite one because it will be in the way

[SVTcobra04]

with the slide carb tho wont i ahve to redo the linkage setup and all...if that will even work....

josh get on msn :D

[apollo]

SVT, here is what you should get

(by the way my bad on the 2 speed link)

O.S. .18CV-RX with slide carb (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGGP6&P=ML)
servo horn for slide carb (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCXF8&P=7)
HPI RS4-3 2-speed transmission (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBTB6&P=7)

and as for the aluminum wheel hexes, dont get the purple aluminum ones and pay $18, if you have a dremel and a brinding bit get these (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJYM5&P=7) for $5.79, i got t hese and all you have to do is grind off the tab, they are meant for an MT2 but i use them on my RS4 with the tab ground off

and do you already have a good tuned pipe?

[SVTcobra04]

and do you already have a good tuned pipe?

thnx, i dont have a dremel but ill see if i know soemone who ahs one...if nto i may go buy one or soemthing i ive always wanted/needed one.

also, no i dotn ahve a good tuned pipe...

and...jw but is this the msot powerful engine u can put on these(RS4's)? :D

[apollo]

for a tuned pipe get this THS pipe http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCPX4&P=ML
or this RD Logics turbo II pipe http://www.rdlogics.com/cgi-bin/category.cgi?item=61235S&type=store i have the RD logics, works great, the only thing you should do for both pipes is port matching the headers, normally the opening in the header is half the size of the exhaust port form the engine, bust the dremel out and open it up, gives you more power all around

and no, the os 18 cv-rx is not the most powerful engine you can put in an RS4, you vould put an os 18tz in it but that is serious overkill, when my os 18 cv-rx was stock it pulled the highest gear ratios like it was nothing at all, now that its modded, its fricken ballistic, but too powerful of an engine isnt good on such a small car

[SVTcobra04]

what kinda motor mounts do i need... and i think ima go ahead and get a new flywheel..so is there a good kind to get? thnx :cool:

[apollo]

good anodized mounts http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCLR3&P=7
crappy mounts http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXN373&P=ML
lightweight 40mm pullstart flywheel http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXM759&P=7

or you can go with the basic cheap-o flywheel that works just fine http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBTA6&P=7 i have 2 of these, one i drilled to make it lighter, the difference is hardly noticable, but idle is a bit rougher with the lighter one, but you choose, $5 vs $18

[SVTcobra04]

tower hobbies is on backorder for those mounts....so do the crappy ones jsut look bad? or are they bad like nto as strong or somethin?

and what kinda screws work with the engine and those mounts?

also, anybody know of like..a kit of screws, with lots of all kinds...cuz i ahte not having any screws :(

and what kinda fuel and glow plugs are good?

gosh im outa everything :D :rolleyes:

[apollo]

the crappy ones just look bad, im sure they arent as strong but you dont need something indestructable, and as for screws, just get a screw kit like this http://hexcrews.com/index.asp?PageAction=VIEWPROD&ProdID=589 i ahve one on my rs4 and mt2, love 'em, just make sure to get a good hex driver set like these http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXFWE7&P=7 i also have these and love them, and for glow plugs and fuel, it depends, on 20% nitro i would get an OS #8 plug, my os always seemed to liek those, also i have to say that the HPi R3 glow plug is quite good, try getting one of each and seeing, and fuel, see what your lhs has in stock

[rs4 rally boi]

another good mod is the racing fuel tank from hpi. the stock one with the primer is an accident waiting to happen... also try and pick up a good air filter and fuel filter.

[rs4 rally boi]

just an updated pic of my rs4 after i set it up to run on-road racing. all the other pics were of the tarmac rally set up. also cleaned up the shock install

http://i93.photobucket.com/albums/l51/mugsythegr8/DSCF0102.jpg

http://i93.photobucket.com/albums/l51/mugsythegr8/DSCF0100.jpg

hopefully ill e able to pick up the new springs, reciever pack, and new tires today.

[apollo]

he doesnt need to pick up a good filter for the OS since it comes with a massive one already, it is a very good filter with large capacity and normally costs $30 to buy separately, so stay with what OS gives you, btw rally boi.....nice lookin car

[rs4 rally boi]

forgot he was getting a new motor :o and thank you

[SVTcobra04]

what can happen with the stock fuel tank?

and that bag of screws includes what i need to mount the engine? also will normal threadlock work on things that get hot, like the engine mount screws?

[apollo]

stock fuel tank ahs a primer and can leak air sometimes, and yes that bag of screws is an entire screw kit for your car, every single screw, plus alot of extraas, and yes, blue threadlock works the best

[SVTcobra04]

is this a tnak that will fit?
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXVK16&P=7

and is this fuel good? also its 16% and OS says it needs 18% lubricant, will this stuff still be fine?

[josh222]

you don't need to worry about oil% they all work great

[SVTcobra04]

i would get a larger fuel bottle than 250CC and also, find a hobby shop near you because if you buy fuel online it comes out sooo much more expensive than buying it at a hobby shop, and do you have to buy 3 OS #8 plugs? you should still try 1 R3 plug

[SVTcobra04]

ordered :)
much thanks to all you guys that helped :)
ill post soem pics when everythings put together by the end of this week :)

btw...does this engine come with special break-in directions? or should i jsut use liek the ones on HPI's site?

aww poop i jsut remembered i forgot to get aluminum hubs :( o well maybe my lhs has em, gotta go there to get gas anyways.

[apollo]

for break in, use this http://www.rcuniverse.com/forum/m_2786285/tm.htm read after the 5th post (#6 of course) and you should be okay without the hubs, maybe your lhs will have them or will order them for you

[rs4 rally boi]

thats a nice list. cant wait to see those pics :)

[SVTcobra04]

cant wait to get my parts :D

[KronicRacer]

then building it is the rest of the fun :D

wow.... it says otu for delivery and it still hasnt came...damn ups :(

[NitroTXT1]

i have one hooked up to a tsais rear exhaust pipe it's the .18ss version...this thing is pretty darn fast i didn't realise the .18 had such power...only prob is something's wrong with my two speed it doesn't shift...but i think imma redo it cause i have a spare.....and imma install my full universals for it....it's gonna be my kick around car...thinkin of getting os .18tz modded out for the next engine

[SVTcobra04]

mounts are wrong :( also i cant fingure otu hwo to get this flywheel on(think im missing a part)

[apollo]

can you get pics? tha would help

[kingsp]

OS .18 TZ (P) Pilot Shaft fits in the RS4 3 SS? "Plug and play"?

Thanks!

[PoweredByNitro]

I just ordered a tsais rear pipe too for my drifter.. I might have to shave off some of the carbon shock tower to get it to fit.. we'll see tho.

kingsp save your money and get a OS 18 cv-rx.. and mod the crap out of that.. ask apollo about this, he's getting insane power!! I'm sending him one of my engines to mod. Put the extra $$$ towards some other goodies

[josh222]

OS .18 TZ (P) Pilot Shaft fits in the RS4 3 SS? "Plug and play"?

Thanks!

the threaded shaft is what you need, pilotshaft (aka SG) needs new mounts and flywheel

[SVTcobra04]

fixed :)
thnx josh.

[NitroTXT1]

that pipe is real nice..and actually doesn't rob the motor of power casue my hpi .18ss runs strong and the car is still fast even without it shifting....but yeah this car is gonna be my drifter/racer...gonna get another z tune nismo body and run speedwaypal widebody finders on it lol basically making it 200mm

[SVTcobra04]

wowww, lol, i really was tired last ngiht, the mounts fit fine, jsut what kind of screws do you use?

[josh222]

did you order the threaded shaft version? and you don't use those needle bearings

[SVTcobra04]

well..its finished :)

[kingsp]

Thanks ;)

[apollo]

the instructions that come with it are very clear, here is mine
http://i66.photobucket.com/albums/h265/hpinitroracer/100_0751.jpg

[rs4 rally boi]

looks very nice svt. if your car has problems ideling just leangthen up the the pressure line about a foot.

[SVTcobra04]

hey appolo, what do you have your mixture control screw and your needle valve at? After the break-in it would speed up slightly then bog down or shutoff when i got on it, so i was messin with the screws, but i think they may be all out of wack now.

[apollo]

set it back to factory settings, lean out the hsn about 1/4 turn, leave the lsn about where it is, you want to be able to get up to temp, which is at least 210 degrees

for break in, follow this, read after post #5 (aka post #6) this guy knows his stuff, he makes fuel for a living http://www.rcuniverse.com/forum/m_2786285/tm.htm

[SVTcobra04]

but whats the factory setting for the mixture control? The O.S. booklet only says the settings for the needle valve.

[apollo]

mixture control are the needle valves

[SVTcobra04]

sorry should worded it better, i meant the mixture control valve screw.

[apollo]

the mixture control valves are the needles dude, how far have you turned the needles since you got it?

[SVTcobra04]

ok, the needle valve on top is 1 full turn from fully closed.
the needle valve on the bottom is about 4 1/2 full turns from closed.

http://i7.photobucket.com/albums/y292/Cobra-Kicks-Ass/osmg2102.jpg

http://i7.photobucket.com/albums/y292/Cobra-Kicks-Ass/osmg2102.jpg

[apollo]

the hsn should be open more than 1 full turn, and when we say from closed, we dont mean completely cranked down, im not sure where my booklet is, lsn at 4 1/2 sounds about right

[tonyt]

ok, the needle valve on top is 1 full turn from fully closed.
the needle valve on the bottom is about 4 1/2 full turns from closed.

your gonna burn your motor out if you HSN is 1 or less turns out from locked. :teacher:

[jasonweremy]

Hey guys. Im thinking about getting a Nitro RS4 3 18SS kit, this is going to be my winter project. I've never built my own rc car before, but I am willing to give it a try. I have been in the RC thing for about 3 months(with a Savage X), and I would like to try to do something on my own. I had some questions about it and I am hoping that some of you are able to help me out in this.

How easy is it to put these together?
How long do they take?
How much do they cost in CAD?
Is there aftermarket parts I can get to make this the way I want it to run etc?
How hard is it going set up the electronics?
Has there been any major problems with putting these together(main problems)?
Is there any advice in general that you guys can give me?(what to watchout for, any hints & tips)

Anything in general you guys can think of please let me know, thanks

[apollo]

going along with your questions, yes it is easy to put together if you know how to follow directions and use a screwdriver, mine was quite easy even for having no knowledge at all, at first anywhere from 5-10 hours would be my guess for complete, proper assembly, but i would suggest here if you decide to get a hex screws upgrade kit (i personally highly recommend them) that you do it when assembling to save time, cost in canadian dollars? well i couldnt find the currency translator but from tower hobbies http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJKT2&P=ML it is listed for $310 usd, there are tons of aftermarket parts, i have mine pretty suped up imo, first thing to do would be new pipe/air filter, setting up the electronics, like servos and transmitter is quite easy, get a good radio like an airtronics mx-3 that comes with 2 servos that work great on the rs4 and a receiver plus an LCD screen transmitter, the electronics just screw in place (servos) and the receiver is sticky taped in palce with double sided tape (i also recommend getting some extra foam tape for padding), as far as putting them together, there are a few things i would suggest, 1. trash their fuel tubing, buy some good stuff that is the color you like, 2. buy a fuel filter, 3. dont follow their directions for tubing length and break in procedures, 4. buy some extra grease 5. get some good locktite for all metal-to-metal screws 6. purchase a radio failsafe, and as far as hints or tips, take your time putting it together, remember where parts go, **make sure not to set neutral on the throttle servo at 80% throttle** (my biggest noob mistake) and also get good tools, a tuning screwdriver like this http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXSL31&P=ML is a great tool to have (i have one and love it) also you will need to paint your body that comes with it so you will want tools likes this reamer and lexan scissors for it http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJGU5&P=ML i have this set, pretty cheap, works great, and you will also need some paint for it, also, follow directions when breaking in the engine and take it slow when you are first trying to drive it aggressively, these little cars are much, much quicker than big trucks like the savage X, so be careful, slowly work your way up to higher speeds otherwise you will crash, break something, and be really bummed (me), well thats all i can say for now, hope that helps, and my RS4 has lots of run time on it, i love it, its a great car, and the 18ss is a good engine

[jasonweremy]

Thanks for the advice Apallo....I almost use the manual like a bible. I found the manual for the engine on HPI's site at this moment and I have gotten some good info on it.(I think) Yeah I am going take a few months(depending on how long winter is). I know its going to be atleast 3 months, so I am going to do what I can when I can, but I want the car to be mine own. I would like it to be like what others don't have, but where I live I am sure that is going to be that hard(the majority of people where I live have trucks ro buggy's),

Does anyone happen to have any vid's of their Nitro RS4 3 18SS?

[SVTcobra04]

ill take soem vids of mine with a OS .18, then once my friend fix's his peace of poop CEN car, ill take some vid of me owning him :D


btw guys i got the tuning stuff worked out, runs without a hitch now, just gotta make a few more small adjustments and ill be flyin!(ran outa daylight today to continue messin with it :( )

[apollo]

im going to my first race tomorrow, i'll see if i can get a vid of my monster modded os in action, hopefully i wont crash

[jasonweremy]

Yeah that would be awsome guys, I wanna see what this can do..

[SVTcobra04]

apollo get video! i wanna compare :D

[jasonweremy]

Yeah did you get that video yet apallo??

[apollo]

yeah screw racing, i dont plan on going to another event again, i got 2 laps around today, and a damn rock screwed up my spur gear, it was the ONLY thing i did not pack extra of, and i was 30 miles away from home, so yeah, my day pretty much sucked, sorry

[SVTcobra04]

dam, ive never had that happen, and i drive in soem ****** conditions.

[apollo]

oh i was sooooo pissed because i spent forever prepping the car, long drive up there which my brother took his day to do, and i got a few laps in, i am still really pissed, and it kills me that its the only thing i didnt pack....maybe my sis's camera will get some street shots (videos) of it

on the other hand, i was one fo the faster acrs there for the duration of time that i was running, came fairly close to a 1/8th's acceleration (he had a .28 in his 1/8th onroad) and he said my car is a very fast 1/10th, so that made me happy in the least :D

[SVTcobra04]

what do you have done to your OS that makes it faster?

[apollo]

lots of internal modification and i can control what goes in the fuel

[SVTcobra04]

awsome, i got it tuned good today, jsut need to amek a small adjustemnt so its off the line pickup is better, but wow, thing is crazy fast now, its almost to fast for the street i drive it on :D btw, shoudl u be able to hear it shift into second gear?

[tonyt]

yea, you should hear it shift into second, but it's not gonna be very loud, just a change in engine tone.

http://i66.photobucket.com/albums/h265/hpinitroracer/track3.jpg
http://i66.photobucket.com/albums/h265/hpinitroracer/track1.jpg

and as for shifting, i have mine set at about 3.5 turns out, shifts fine

[SVTcobra04]

heh, thats funny you got the filter on the pressure line, i was just thinking about doing that today, just to add an extra level of protection. and, whats the tubing ontop of the heatsink for? I need to do something like that...seeing as my heatsink sticks out the top a little bit and it would suck to flip :( .

[apollo]

that is jsut a spare canister i put on there, there is no filter element in it, my lhs sells filters like that and i havent really seen any else like it,its just an expansion chamber that i found helped out with performance somehow, call me crazy if you will, and the blue tubing zip tied to the head is for when i run my truck really hard, i do alot of jumps and that tubign on top of the head adds a great deal of protection, its still a good idea to run it on an onroad because sometimes you get violent traction rolls or you hit a bump in a turn, ect, basically its just padding on the head, i also replaced the normal semi-clear pull start tubing peice with some blue fuel line like on the head, it looks custom and way cooler, plus i dont have to get my hand anywhere near that hot engine

[SVTcobra04]

well, video cam messed up :(, i ahd gotten a few runs in before my glow plug ignitor pooped on me, ill try again tommrow.

[apollo]

what is the glow plug like? if the element is broken then it was ran way too lean, usually

[SVTcobra04]

woops, sorry, it was my glow ignitor that pooped out, all it needs is a charge :( :D

centax clutch: a clutch that uses centrifical force applied on those little BBs to push the clutch pads outwards.....and engage the clutch.....basically, a complex clutch spring.

There mostly for racing, the engagment point is adjustable so you can get it to kick in at higher rpm where theres more power

Alright guys, after lurking for a while, finally need to post for some help please....

Finally got my Picco Xp 12 the other day but its proper stressing me out now....please can anyone help me get this into my RS4 Evo??

Firstly it has an sg crank, no real problem as i've got an ok flywheel nut for it, but the shaft on it is only about 300mm long...now this is way to short, about 10-12mm out to fit my standard clutch and flywheel on to it...so i'm worried this engine may be uselsess?

Has anyone else got this engine, what flywheel clutch combo are you using? is this a standard length for an sg crank, and will the centax clutch fit any different?

Josh Would you be able to shed any light on the subject too, as you have a centax...

If people could have a look at the pics and throw any ideas up for me that would be great, as i'm pulling my hair out over it.....would a stainless bush/spacer machined to size to make the distance up be acceptable or would it be unsafe as its spinning so fast??

Are there different cranks available for it to buy from picco?

Any help greatly appreciated...cheers guys.

[josh222]

your going to need to get either the hotbodies centax and engine mounts or get a new flywheel and adjustabe engine mounts. with a proper flywheel you can gett he clutch setup on there but it will still be shorter and need ajustble mounts to move engine forward. I would go with the centax, its 36.99 and 15 for its mounts

Cheers for the quick reply josh, post on universe too,lol...desperation!...mite look in to the Centax now that i no it will fit, was worried i had a shorter shaft than normal(not in that sense before anyone says,jk!) I flywheel is the cheaper option i think, and mounts shoudn't be a problem, got some on my inferno, so can steal them...just glad the engine aint scrap, was starting to worry i'd wasted my money!

can't wait to get it all back together and on the track.

cheers bud.

[josh222]

make sure there adjustable and perferibly non pull= lower highet

[supermoto552]

make sure there adjustable and perferibly non pull= lower highet


Just been down to the garage to check, bugger...can't rob the inferno mounts, forget thats a .21 engine, mounts a way to big....back to my lhs tommorow it is then...still mite get the centax, just a pain they dont sell them here in the UK, grrr!

I'll keep ya posted how i get on...getting impatiant now...huh.

[rs4 rally boi]

in the pic b4, is that the hot bodies clutch you were telling me about?

[supermoto552]

Finally got my flywheel and clutch on to this .12 Picco and it all fits nicely in to my Rs4...just, with a little fiddling, and lots of swearing!

Lets hope it goes well.....

[metalslug831]

Hey, I am new to this forum. Glad it's active with Evo/18ss users. Was about to sell my car, but took it to HPI. They gave me a new carburator.

-What servos are u guys using? I use a hitec high torque MG servo for steering.

-Anyone have problems with the steering? Mine seems to not want to turn enough

-Throttle problems? sometimes I can't get it to sit still, I know 1mm of the hole should show, but sometimes the throttle linkage gets messed up.

[apollo]

any standard servo is enough to turn an RS4, they arent beastly heavy

sometimes a low end servo will not be able to turn the wheels all the way, or maybe you dont have enough voltage, or your tires could just not be gripping, if they are the stock tires, there is your problem

and just turn the throttle needle until it stops driving around without you doing anything, a lean low speed needle can also do this


on the other hand, guys, im sorry to say this, but i think im gunna sell my RS4, too few of places to run it around here, you all know what all i have on it (i put the 18ss back in, not the OS) so if anyone is interested to buy, PM me, thanks
Sean

[metalslug831]

I messed with my needle settings. Now my car just dies after I start it. How do I reset my idle needle?

How do u adjust the 2 speed? I used the hex wrench, but there is no attachment.

[zquikone]

Hey everyone. I've been reading through all the posts here and I've had my RS4 3 Evo for about a month (my first RC car). Still have the stock T-15 in there and have no plans to swap out the engine. I'm really looking for suspension upgrades and brake upgrades so if you guys have any advice, that would be great.

Here's what I got so far:
Graphite upper deck
Graphite front and rear shock towers,
Sway bars
Foam tires
fiber brake disk (s**ks ***, any other suggestions?)
racing clutch
aluminum threaded shocks
red springs (my preference).
replaced every dog bone with CVD's

I'm just playing around with the weight of the shock oil until I find one I like. Other than that... anything else you guys think is a worthy suspension upgrade? I like trying to hit turns at high speeds.

[apollo]

thought of the graphite (i think hey are graphite) A arms? should get rid of some fo the slop, and some aluminum bulkheads would also help get rid of the suspension slop, i found that i could take alot faster turns with the stock black springs than anything else, also, have you thought of some titanium turnbuckles? hpi makes a kit for that

edit: metalslug831, just set the idle needle to be open about 1mm at neutral, and you adjust the 2-speed with a hex wrench, mine shifts best at about 3.5 turns from bottom, but make sure you are turning the correct screw, one holds the 2-speed clutch in, and one adjusts it, also, threadlock the set screw in place once you have the optimum set point, i have had mine in the same place for about 4-5 months

[metalslug831]

What u mean 1mm from neutral for the idle screw? I don't get that. Anyone else have engine problems? Like at startup, it dies when i apply throttle?

:teacher:

[apollo]

ok, when there is no servo input (neutral) set it to where the carb is open about 1mm, just turn the idle screw clockwise i beleive, and its not an engine problem, too many people blame their problems on this, tis a tuning problem, if it dies when you apply throttle it is most likely too rich on the lsn

[metalslug831]

Ok, i tuned my engine. Seems to work fine now. just cleaned it up, the chassis and all. What spring color do u guys use? What about steering and cornering improvements?

[apollo]

i use the stock HPI black springs, to be honest they seem to work the best of the blue and purple springs i have tried

[kingsp]

How I can install O.S. .18TZ Pilot Shaft in RS4 3 18SS? It's possible?

Thanks.

I'm with the same problem! How you solved this?

[zquikone]

Thanks for the tips apollo. I'll take a look at the bulkheads. Are they the same ones i can find at rcmart.com?

The black springs are good, but when I hit bumps in a parking lot, the car wants to turn and doesn't go straight so I went down to a slightly softer spring. Maybe I'll try the black springs again and go with a lower weight shock oil. I got a lot of tinkering to do. If anyone has suggestions for parking lot settings, I'd like to get suggestions on that.

Also, does anyone know of a good brake set-up?

[josh222]

adjustable engine mounts and a different flywheel and clutch nut

seems like my mt2 bulhead would fit, but i'd get those

[metalslug831]

I also only have time for parking lot bashing. The Evo I think is great for bashing. I do not need a front one way, racing clutch or CF brakes right? If anyone has a good setup for parking lot bashing, let me know.

-Does anyone use the pullstarter? I ordered one b/c I am sick of using the rotostart. I rather just pull it. Let stuff to carry and worry about charging up the rotostart.

-Racing tank without primer- I placed an order for this b/c I was sick of priming it. I just want a reliable startup.

-Aluminum steering from Hot bodies- Just placed an order, hopefully this will add to solidify cornering and steering.

-DIRT? How do u guys keep your cars so clean? I guess it's because I drive it around in the parking lots. Mine is caked on with dirt everywhere. That's why I still have my plastic stock battery cover. Keeps the receiver and battery clean. I still use the stock controller b/c my hands get greasy and I don't want to dirty my other radios.

-What fuel do u guys use? I was using the stock HPI fuel, but I switched to some other stuff from Traxxas.

[apollo]

for bashing you dont need anything special, but i do like my racing clutch, wears less, better acceleration, and hpi's pull starts are slightly weak, eb care ful when using them, dont pull them out too far, the steering sint your problem, your problem mosdt likely is with the servos and tires, i ahve the hotbodies aluminum steering assembly, it helped steer a little bit beter but not much, replaced the bushing inside with bearings for faster turn time

and as for dirt...
http://i66.photobucket.com/albums/h265/hpinitroracer/fsrs4topview.jpg
need i say more? lol :D i only cleaned that up because im selling it, i used wd-40 and ompressed air, sometimes alcohol and compressed air, thats it, normally i just put it up dirty

for fuel, dont use traxxas, if you can, use trinity monster hp, byrons, or hpi's stuff since they specifically recommend it, hope that helps

[josh222]

simple green works great for cleaning, i mix it 4parts water to 1 part simple green and its still plenty strong.

What servos do u run? I use a metal gear hitec servo for steering and the standard airtronics for thorttle.

Sometimes fuel sprays from where the glow plug is. Gets over the servo for throttle too. Anyway to correct this?

[apollo]

if it sprays from where the glow plug is your washer needs to be replaced or you arent cranking the plug down tight enough

[metalslug831]

Any nitro drifters out there? Anyone have reviews of the Stage D conversion kit? How about the D box?

[tonyt]

well, one of the people i met in NYC (friend's relative) has a D-box in his RS4 3 EVO and WOW!

words don;t describe how it made the car handle...you could drift all day, rain or shine, and you can always hold a drift, just like in the movies :D

Tony T.

D-BOX = EXPENCIVE?!? is it just me, or does $120 sound like a rip-off?

HATE FRESHMAN RHETORIC :bang::teacher:

[metalslug831]

There is a no name D box that goes for around $40. I think it is just rebadged with the HPI sticker

[metalslug831]

Will the OS CVRX be able to use the same pinin gears and fly wheel from the stock engine? Basically plug and play with the addition of engine mounts.

[apollo]

yes, but get higher gearing

[PoweredByNitro]

anyone have alloy diffs or bulkheads on the RS4 with sway bars?? I'm not really sure how the sway bars are suppost to stay on. On my 18ss with plastic diffs and bulkheads a part of the diff keeps it from falling out.

got a link to this no name d-box??

d-box is kinda cheating since it does the work for you, but on the HPI D-Box you can adjust how much it helps u, until you don't need it no more. good tool to improve your driving.

I'm in the process of building an RS4 3 Drifter I'll post some pics in a few.

[metalslug831]

There is a thread on this site about D-box. The one that's cheap is the GWS Gyro. No kidding it's cheating. But for parking lot bashing, it's fun.

[metalslug831]

Ok guys, I picked up the GWS Gyro. Trying to set it up, anyone know how? My servo just goes crazy.

Hello PoweredByNitro,

[metalslug831]

What is your drift setup? I don't want to buy the Stage D kit. Anyone have a good setup? I locked my rear diff. Should I lock the front one? What spring color to use?

[tonyt]

YEA! LUCKY YOU! if i were you, i'd let them post the pics!

Tony T.

PS that just shows that rc car companies read these fourms.

[PoweredByNitro]

Thanks for the compliments guys!! The Chassis is a GPM.. haven't really seen many of them but they do have them on ebay. its 3mm all over but the raised parts are 5mm, an extremely tuff chassis. All the parts were stripped then polished.
tsais.. you can definately post some pics, I'll take some better ones though. That will really show off the pipe.
Well I haven't drifted this car yet.. I tried drifting with my 18ss and was a pretty stiff setup, so for this car I'm gonna try a softer suspension and see how that goes. My diffs weren't setup for drifting on the 18ss either. On my drifter I have the rear diff pretty tight and the front diff kinda tight. I might want to get a one way for the front and then lock the rear. Just depends on how it drifts. You don't really need the Stage-D kit but it will balance everything out a little better. Its all up to you, I would rather put the money towards some good radio gear,drift radials,rims, or some hop-ups. I put a lot of work customizing this car to my likings. Thanks for recognizing ;)

[metalslug831]

Should I get a 18ss or OS 18 CVRX? The 11J CRVX is the one to get right? Which gears should I get? Do I need engine mounts? That's it right?

[tsais]

Hi PoweredByNitro,

We would appreciate it if you could email your photos to info@tsais.com. Thanks.

TSAIS Team

[PoweredByNitro]

ok, hopefully its nice out tomorrow and I'll snap a few shots.

metalslug - the OS is the best bang for the buck, can't go wrong with an 18ss either. you will need higher engine mounts, purple or some cheap aluminum ones if you don't already have them. check back a few pages I think hpi apollo mentioned them ;) if you have any questions bout the OS he's the man to ask :teacher: get the slide carb vers. also get a higher gear ratio, red pinions with 39,43 spurs I believe. Thats meant for speed, you can use it for drifting too, I had that setup on my 18ss and it seemed fine. My RS4 drifter will have stock gearing to start out since I'm using a .12 CV-RX, I'm also having it so the 2 speed doesn't shift during a drift.

[metalslug831]

So the 11J version?

Aluminum motor mounts

Red gears

39,43 spurs. That's it?

[rs4 rally boi]

srry to be abother but all the gpm chassis ive seen look like this one here (http://cgi.ebay.com/GPM-Alloy-3MM-Main-Chassis-fits-HPI-Nitro-RS4-3-III_W0QQitemZ170042263157QQihZ007QQcategoryZ34063Q QssPageNameZWDVWQQrdZ1QQcmdZViewItem). yours looks realy good though, real rigid.

[metalslug831]

picked up a CVRX. Got those ugly alum mounts. Doesn't fit in the stock chassis holes. What to do?

[apollo]

which mounts did you get? if you are talkinga bout the $4 cast aluminum ones, they will fit

metalslug they should fit.. like apollo said. take some pics and post them if its still not working, so we can see whats not lining up.

Trying to mount engine corrrectly, doesn't want to fit. Can anyone help me out? Flywheel doesn't move either, engine doesn't want to start.

[X-factor]

I had the same problem when I installed this engine with the THS pipe. I had to put a notch in the chassis right where the pipe joins the header, so the engine would sit flush. Might be a better way but that is how I fixed it.

X

BTW I would pick up a set up of the heavy duty diff ring and pinion for front and rear. This engine will shred the stock units.

[apollo]

k the flywheel wont turn easily because its a new engine, it has lots fo pinch, and it wont want to start much until you heat it up with a hairdryer, also, get higher gearing, it moves the engine over a little, and i dont see why the mounts wont work, they are the right mounts, just loosten the other 2 screws and thread all of them in

[metalslug831]

Where do u heat up the engine with a hairdryer? I have a racing fuel tank from hpi, sometimes it doesn't want to bring in fuel. Do the lines have to be a specific length to take up fuel? Any sites for engine break-in?

[apollo]

head up the engine with a hairdryer, not a hard thing to do, just blow it all over until its fairly hot, and no, lines dont need to be an exact length, you can either cover the exhaust hole with your finger and pull the pull strt or take off the pressure line and blow into it, and here, this is for break in http://www.johnnycoolguy.com/JCGR/main/tech_break-in.html just get the engine a little over 200 degrees and you will be fine

[PoweredByNitro]

yah I forgot to mention that.. the pullstart on the OS's is pretty big so you have to modify the cf upperdeck or stock radio tray to move the engine over a bit. Not really sure about the stock radio tray but on the upperdeck you have to do that. I'm getting a roto backplate which should let me move it without modifying.

[metalslug831]

Is the rotostart plate compatible with this OS engine?

[PoweredByNitro]

yup this one is Durutrax OS roto backplate (http://www2.towerhobbies.com/cgi-bin/wti0001p?&W=001161581&I=LXHPS2&P=K)

[metalslug831]

Great, things are working now. How do u fix slop on the steering? Sometimes it isn't straight, I fix it, and it gets messed up again. Do those metal servo horns work?

[SVTcobra04]

I had to cut out a notch in the plastic on w/e the part is called to fit my OS, that starter coil or w/e is pretty big.

[metalslug831]

Man, I am luving the OS CVRX. With this new power, what else should I make stronger?

[SVTcobra04]

anyone ever try running these things jsut RWD? LOL.... yea anyway iw as thinking, maybe get some big tires and drift with it :D

[metalslug831]

RWD is competely uncontrollable. Don't know why, when we have 2WD stadium trucks

2wd stadium truck is made to be rwd, it has the weight balance for it. The rs4 is made to be run 4wd and it layed out in that manner to handle properly 4wd

took the words right out of my mouth. its about how thier weight is distributed around the chassis.

[rs4 rally boi]

Hi guys, it's been a long time since I've been on here. Nice seeing how most of the new guys before got their cars looking real nice.

I was just wondering though why most racers have zip ties around their heatsinks.

[apollo]

if you flip your car, it helps protect the engine head from hitting the ground and it keeps it looking nice

[69cam327]

I've been thinking about getting one of these theres a huge parking lot next to my house freshly paved. Its either this or the new 4tec 3.3 But not sure yet cause i heard the belt drive cares get messed up fast if the lot isnt clean.I know this lot wont stay perfect forever thats y I like the fact the rs4 is shaft.

[69cam327]

R these hard to tune? My nrs4-2 i could never get that thing to run right it would always mess up but than agian i was 12 and didnt know much. So i bought a e-maxx and really dont like electric it sucks having to charge batts so i sold it. So like i said above I'm looking to get back into Nitro.

[69cam327]

What's the differance between rs4-3/evo/ss?

[apollo]

69cam327, you are a noob, the 4tec 3.3 is waaaaay overpowered for you, it is for some good drivers that have been in nitro for a few years, its just too fast, engines are not hard to tune, jusdt read the tuning guide in the nitro section and you'll be set, also the rs4 evo is a rtr car that has weaker parts and a weaker engine, the 18ss has upgraded parts and a little larger engine

[69cam327]

I figured the 3.3 was way to much anyways. I might so do the 18ss. Maybe a rtr ntc3 drove one today at my lhs and I liked it to.

[rs4 rally boi]

the ntc3 isn't a bad choice, i think that you would be happy with either.

[69cam327]

I just dont want to buy the ntc3 and then a new one comes out thats better thats my luck plus i really like both.

[rs4 rally boi]

i fealt the same way before buying my first nitro rc, but after i drove my rs4-3 i was happy with it and didnt real care about if hpi came out with a new version, which they did. if your just gonna drive in a parking lot, it doesnt get much better than a tc3 or a rs4. if you havnt driven an rs4-3 try it out and see if you like it better or the same. and if you still cant decide, hell get both! :D

Hey everybody, I haven't posted here in quite a while but recently rediscovered the joy of my rs4 3. Here's the carbon fiber chassis I just designed and made for myself this past weekend.

Let me know what you guys think. It was a hell of a project full of headaches.

I was also wondering if anybody could tell me where I could find the extended ball joints that come with the carbon fiber shock towers. I made one of those for myself too and now the shocks don't quite line up right.

Also, can somebody tell me what kind of ride height I should be looking for for a fairly rough surface? Thanks a lot!

[josh222]

i would build some kind of aluminum plate for the engine area. Nitro cars don't really use graphite or carbon because they use the chassis to help get rid of the heat. It does look nice

[rs4 rally boi]

its gorgeous :) have you driven it much yet?

[AminF3]

No, I live in PA so it's been very cold and icy here so no chance yet. Pretty poor timing on my part. Next time the temp goes up you know I'll be out with it though. Any ideas where I can get those longer ball joints though? And what kind of ride height do most people run for a not so smooth road?

[the-one1]

Aminf3: If your talking the longer ball join for the shocks, HPI makes and extender for it for their CF shock tower. Or you can get computer motherboard stand offs of the right thread.
