The EMT was created first, then the NMT using the EMT's arms then the RS4 3 from the NMT's layout so they are all linked one way or another.

I just recently purchased a Fantom FR15 03 and a 2-speed option from HPI (purple pinion gears). Does anybody here have the same setup? How fast can your car go? I only have a few mods including the HPI super chassis, graphite upper deck, aluminum exhaust header (from Type SS), aluminum tuned pipe and I'm running Ellegi foam tires. Thanks.

[HPI-Fan-4-Ever]

i have that same engine, a 2spd, upper deck and foams also. i recently put on the optional gearings (the red pinions), so i need to readjust my tranny, and my engine is a little rich cause of the weather, but it easily goes 50+...

with some small adjustments i know mine will go 55 or more....maybe close to 60 cuz of how i have my gearing

my engine is worn anyway, soon i'm going to get hpi's new .18 engine or perhaps a wasp .18, show up those 1/8th's runnin at my track >:)

list of mods
2spd
Fantom FR 15
graphite upper deck
graphite rear shock tower
graphite front shock tower
titanium turnbuckles
titanium screws
TRC foams
optional 22-19 tooth gearing ( i think thats it??)
dynamite tuned pipe
custom pipe holder


too much money put into it :(

Kronic, did you ever tell me where you got your purple tranny mount? its a pain the rear to adjust my tranny :(

[KronicRacer]

yea heres the partnumber and link for it #HB61130 Center
Bulkhead set
they acept paypal www.meganitro.com (http://www.meganitro.com/hb%20nitro%20hop%20ups.htm)

[HPI-Fan-4-Ever]

awesome! thanks man, thats great that they accept paypal cuz it just so happens that i have some moola in there.......


holy crap :mad: :mad: :mad: i have 41.52 in paypal and the thing cost 42.50....sheesh..... go figure

[mbx5]

hey guys...
i have an evo and i wanna just use it for regular bashing. Is there a differnece on the rear knuckle? I have #1 and #2. Everything else is prety much stock setting. I usually just bash anywhere i see flat. I find the stock tyres wear out really fast. What kind of foam tires are good? for all around bashing fun:p

[Kenny T]

2 deg toe in will give you more traction on the back, less likely for the back to step out and get sideways. I think that's right, it's something along those lines. :D

[mbx5]

are all on road cars like this? when you have to make adjustment you have to change those plastic parts? or it's just the rs4??????
how about other cars like R40, tc3, mtx3, etc??!?!:confused:

[HPI-Fan-4-Ever]

if you mean change the plastic parts for suspension adjustments, then for the most part other cars have adjustable things on them....if you don't have any, get a set of titanium turnbuckles and RPM or Losi ballcups...i prefer Losi, they have almost no friction.....as for the RS4 i am still looking for a way to get a pivot-ball suspension in the rear.....but yes, to adjust toe and stuff you gotta change parts :(

[Kenny T]

The cars you mentioned, no you do not have to change parts to adjust susp setting, they have pivot ball suspension.

The RS4 3 does not have PBS so you muct change parts to change toe(rear) and castor(front).

[mbx5]

oh yeah i'm asking cuz RS4 is the only onroad car i have and i thought all onroad cars are pretty much the same. :)

my take off on my t15 is kinda slow... change clutch shoes? i dont' really wanna loose my top end so no dropping down the clutch bell.

[mbx5]

I have a stock rs4 evo and how do I make it faster??? TOP speed I want to able to pass 60 mphs

I have the sirio .18 tx, lots of other .21 pullstart or none pullstart engines. maybe get the .21 chassis?? please help!!!!!!!

[Kenny T]

Clutch, HPI racing clutch or that MIP 4 'n' 1 or something like that. Get a Centax if you can afford it.

Engine, Stick the 18 in there and gear up. The other option is to get variable engine mounts and widen out the engine mount holes by about 3mm with a dremel. That should accomodate a 21 but make sure it's non PS. it'll hit against the arm. It might not since the information I'm giving you is from the NMT(same drivetrain, no difference) which has longer arms that travel more. Just equip a non-PS to be sure. This is the cheap way. The expensive way is to buy the Wolfpack 21 conversion.

[HPI-Fan-4-Ever]

i wouldn't try putting in a .21 unless you know exactly what your doing....besides, HPI's new .18 engine drops right in and can send your car to the 60mph mark, it even says so in HPI's site....you may have to gear up some, however

[Kenny T]

18's should be fine, I'm thinking of getting the OS 18CV-R(X).

[mbx5]

hi guys, i was playing with my rs4 today and does this car just suck for regular bashing around?? I have everything stock except foam tires. My steering seems quite bad. Will upgrading a better servo helps? Also the throttle linkage isn't that good. Any help on this? :(

[mbx5]

i am also using a 6 cell pack and all the settings on the car is stock. Is it really this bad? I also have 6v hump pack.:confused:

[Kenny T]

Getting a new servo will help a lot. Try and get a Carobn Fibre upper deck, it improves the handling a lot.

[stoopideric]

I am selling my RS4 3 SS it less than a month old just rolling chassis and motor. Make me an offer ewilkins2@triad.rr.com

[rico750sxi]

Kronic, had some 50* weather here this weekend so I broke the car out. I switched the fuel tank to a new one first though. Don't know if it was the weather or the tank but it ran great. I got 43mph on the Venom Speed Meter which isn't as high as I hoped(of course!!!) but not bad. The Fantom is still pretty new, less than 1/2 gallon through it. Now I can switch pipes and such to see if I can improve. Thanks again for your help.

[HPI-Fan-4-Ever]

mbx5-

where do you drive your car? is it in your street or a parking lot? depending on the road conditions, foams may not be the best choice of tire...if your place where you drive it is dirty and has loose gravel then try rubbers...the foam is more for prepared ashpalt that is clean....

also, if you mean bad steering as in it doesn't turn enough or slides easily, here is a solution. on your transmitter, make sure your turn radius is set to the lowest setting, that way your car turns as sharp as possible....and if it slides easily, try lowering the ride height..this lowers the chassis roll

for my street, i have the car as low as possible, i have some dirt rally tires, and the smallest turn radius....

one more thing, get titanium turnbuckles....and losi/rpm ballcups, then set about a 1-2 degree toe-out in the front, it will let your car turn more aggressively....

nvm, one more thing! try rebuiling your shocks with heavier fluid, or stiffen the shocks with spacers...

terribly sorry about all the talkin, but just sayin that your steering is bad is a vague statement.....i certainly hope this helps! first thing though, change to rubber tires and see if that helps, a setup is useless without the right tires.....

good luck and have fun!

[mbx5]

thanks HPI fan 4 ever for the feedback!

I think I am just going to use the RS4 evo to pratice my driving skill and I know why I found out why my steering was bad. The hubs in the front are damaged and I replaced all of them and bought new foam tires.:)

[mbx5]

anybody know how to fix that throttle linkage???? mine is screwed up that spring inside won't come when I turn them. It's very sticky so when I apply brake it acutally give me 50 % of throttle. help!!!!!!!!!!!!! i used wd-40 and doens't help:(

[HPI-Fan-4-Ever]

mbx5,

you are being unclear....post a pic of it if you can....so basically you are sayin that when you hit the brakes it opens up your carb instead???? and when you say the spring inside, what is it inside of???? is it the arm going to the brake pad, or do you have a throttle return spring on it????

[KronicRacer]

sup guys. been busy with the xray m18. what a wicked lil ride.

hey rico. glad to hear the car is up and running.

[dwayneed]

I just ordered an RS4 3 SS, this will be my first nitro car. I have a 2PEKA tx/rx that came with 2 S3003 servos, will these suffice? I will be using the car for fun and maybe racing friends if I can get them into nitro....

[rico750sxi]

I want one of those M18's, they look awesome. I have 3 Micro RS4's now, it'd be a nice addition. Thanks again for the help.


The S3003's will work just fine for you. You can upgrade in the future.

[C0NTENDER]

Sorry for the splatter guys, but I thought some of you should know what's going on with the HPI challenge this year if you don't already know.


Thanks for the question. We've been doing the standard HPI Challenge series for several years now and everyone's had a great time. In order to keep getting the race coverage in the magazines we need the series to evolve to keep up with the hot trends in the industry. So this year we will shift our focus a little to emphasize the Savage trucks.

We're planning two Savage Slam events that will be fun events like the one we did last year... racing, Savage Bowling, concours, long jump contests, barbeque, prizes etc. The idea is to get together for a fun truckin' event with friends and family. We're shooting for one event on the west coast and one event on the east coast, both in the Summer so that the whole family can attend.

For the HPI Challenge, we're planning one event with the format basically the same as in previous years (nitro and electric sedans), with selected winners getting a free trip to the HPI Challenge World Finals in Europe. The race will probably be in the Summer, somewhere in the middle of America.

If your not happy about this, please go to
HPI Challange (http://www.rctech.net/forum/showthread.php?s=&threadid=34825)
If you wish to make you opinion known.

[HPI-Fan-4-Ever]

I have a few questions on these HPI Challenges, since I very much hope to attend one this year:

How does the racing go? Are there different levels, like rookie, stock, modified, etc? And is it broken up to different cars, like an RS4-3 class and an R40 class? Racing one against the other isn't really fair......

also, exactly what goes on? Is it just like a big HPI r/c party? Thanks for informing us about the challenges this year btw.


also, off subject for a sec, I just bought an HPI racing clutch to go on my Fantom FR15, anything I should know first about it, or will it go on trouble free?

[mbx5]

what kind of clutch is good for the RS4 evo? I want faster take off. Also will motor saver filter provides any performance gain or it's pretty much just prevents dirts? I think it just prevent dirts.

[HPI-Fan-4-Ever]

well, it depends, are you just bashing the car or racing it? if your racing it competitively then put a centax racing clutch on it....however like i said above i bought an HPI racing clutch, its not as complicated as a centax and all but it is much better than the stock clutch and is good for bashing, hopes this helps

[reptilian]

Besides EVO 2 being RTR (with painted body, roto start, etc.) & SS kit - with all the building, etc., which is a better car?

Are they exactly the same just different Engines?

If they are the same, which do you prefer & why?

I don't race, just fool around in parking lots. Mostly, I TINKER!!

I am currently driving an Ofna Hyper 10 Touring Car & have enjoyed it, but I want to be able to just walk into my local hobby store & mostly, be able to buy what I need. There are 3 shops in Houston, TX that carry touring car stuff & two of the three have tons of HPI stuff. The shop I use order parts for me anytime I want, I just "HATE THE WATE"

The Reptilian Kind

[Jason C]

I thought the EVO2 was basically a RTR version of the SS. Anyways, I prefer the SS kit over the EVO2 simply due to it being a kit. I never did like RTRs since I like to wrench on my cars and install my own radio gear. Often times, I will substitute in hop-ups while I'm building a kit - a RTR would make much more hassle.


I think I managed to successfully seal the diffs. I made some silicone seal washers from the generic silicone sealant and stuck them between the diff ring and plastic body. The outdrives already have O-rings so I didn't bother with them. I filled both diffs with silicone lube and no leaks so far.

hmmm
well with the evo you cant adjust camber. and the radio you get with the rtr, rtr evo are really not worth keeping (theres no adjustability to it) so the ss is a better route to take. get the radio gear you can use later on, now(imo). the engines are completely different on the both of them. the evo has a .15. while the ss has an .12 the .15 should easy to break in. while the .12rss is not it takes alot longer to break in before you start seeing the motors tru potential. so far ive heard the new .15 hpi motor has is a p.o.s. then ive heard differently thats its an awsome engine. either route you take there will be no shortage of parts for tinkering.

[xkylar]

Do you guys have any gearing recommendation for a Fantom FR15 '03 engine. I just recently installed the optional red pinion gears but I still have the 47T and 43T spurs that came with it. What can I change those spurs with to maximize my engine?

[HPI-Fan-4-Ever]

xkylar:

i too have that engine and the red pinion gears. as for the others i would gear up a couple more, the FR15 is a decent engine and you can get up to a nice speed with it.

and can someone tell me which way to turn the setscrew in the 2spd tranny if i want a later shift point? i had the manual but lost it so i checked on hpi's site in the SS intruction pages but i cannot find it

thanks!

[xkylar]

You need to turn it clockwise to make it shift later.

[rico750sxi]

The two speed instructions are on the website, look under the manual link for the RS43 SS.

[KronicRacer]

it seems that hpi has the spurs available finally!!

[p.n.e]

anyone gone .21 in their car? i put a ofna hyper .21 in my rs4 and this thing is absolutely insane. its the car i've spent the least amount of money on but is the funnest to drive.

[HPI-Fan-4-Ever]

i just installed a racing clutch, hopefully i did it right....you cut apart the 2 "shoes" of the clutch, slide them on according to the instruction, and clamp the spring around it, correct? it seemed too simple to me......but it seemed to go on perfectly

[KronicRacer]

the racing clutch is supposed to snap in 2 its very easy to install . its when you start cutting that it gets hairy. :cool:

[HPI-Fan-4-Ever]

anyone seen hpi's new full-scale sponsored ride? it is SWEET! its a 2004 impreza sti, if you haven't seen it, go to hpi's site

in the pictures it shows a pic of an r/c car done like the full scale, is that also an impreza shell or something that looks like it? i really want a shell like that now :)

man thats way cool. im thinking about getting an sti myself since my stang was totalled this past tuesday, 95% of my rc equipment escaped unscathed the other 5% just shells but.... .:mad:

--------------------------------------------------------------------------------

Installed a new RPM flywheel on the T-15 which is on the Evo. But there is one problem. The motor mounts don't line up. I got on there the Cheapo HPI mounts.

Also the engine mounts dont' line up with any of the mounts on the chassis there off by a hair. The mounts on the chassis only allow movement from side to side but not front to back, ie starting down at the car.

So I though my flywheel was not tight enough, but it's tight alright.

Any hints on some motor mounts, like adjustable ones and such and also pics.

Thanks for any replies

[HPI-Fan-4-Ever]

hey jjl, are those super nitro wheels on that thing? bling bling! time for some chameleon paint and a neon kit lol

ALso any other suggestions you might have.

Thank YOu for any replies

[Kenny T]

The engine will fit but you will need to get a slide carb linkage set.

TJNMT, I've seen adjustable engine mounts for around $USD20 they were made by GPM.

[jjl]

hey jjl, are those super nitro wheels on that thing? bling bling! time for some chameleon paint and a neon kit lol


You'll have to ask HPI, it's their pic, but i think the answer is yes.

[TJNMT]

I looked around for those GPM adjustable mounts and found none. But check up on wolfpack. I emailed them and still waiting for a response. But will these mounts work
http://www.wolfpackradicals.com/html/adj_belt_car_mounts.html

Or maybe these mounts.
http://www.wolfpackradicals.com/html/adj_shaft_car_mounts.html

Thank You for any replies

[KronicRacer]

well the thing with the shaft mounts is that they are for non pullstart engines(mounted way lower) the rear plates get in the way and the evos carry the roto start too.. so an alternative is to get stainless steel spacerswashers or aluminum spacers/washers to use with the shaft mounts. i havent used the belt mounts from wolfpack so i have no idea on the specs (they may work) later on you may get a new non pullstart/non rotostart motor and want the lower shaft mounts whaich to me are more secure. :cool:

[TJNMT]

yeah I got an email back from wolfgang and gave me an update on what I need. I got 3 cars 2 of which are non pull start it's just the evo and the T-15. thanks for your help

i was wondering if a 37 tooth spur gear ( hpi part number is a442) will work on my rs4 3

please let me know
i have email hpi forum 4 times and never get anything back
thank you

[KronicRacer]

nope that part isnt for the nitro 3 (specifically) every thing has got to remain within 4 teeth spur and pinon. use a 45t for first and 41t for second this also depends on the motor you are using. please check link below. :cool:

hotbunz you made a wise investment, but reverse? throw a .12 rossi in that thing and get it down the track. :eek:

[HPI-Fan-4-Ever]

electric cars go in reverse too......there's also no way to get the reverse module for the savage on there too....too bad, reverse would be kinda cool, not for racing obviously

is it safe to take the pressure nozzle off of my pipe and just fit the fuel tubing straight into the pipe? i am having big probs with it......would this burn up the fuel line?

[KronicRacer]

you can do that. and it wont burn up the line. :)

[HPI-Fan-4-Ever]

yes! would anything like JB Weld be necessary to hold it in there, cuz i certainly wouldn't want it to slide out

[KronicRacer]

ok first of all what kind of pipe is it?

[Scott S]

Nope, just stuff it in there, not too tight or too loose. If it's too tight, try and enlarge the hole slightlllly until it fits snug. If it's too loose, try another type of fuel tubing which is a little thicker. If it falls out too easily, wet the end of the fuel tubing with a little bit of windex, it will hold it in place a little better after the windex evaporates.

[HPI-Fan-4-Ever]

its a blue Dynamite tuned pipe, 2 pcs...unfortuneatley the nozzle is on the opposite side of the where the exhaust hole is......so it is in a problematic location

[chevy_94]

Who owns a EVO and do you like it cause i am goin to get it in two weeks if i get good things about it. i could go get it now but i am still trying to fix up my t-maxx i just bought 2 weeks ago.is the EVO durable? fast?

[JDuncan]

I am lookin into buying an HPI RS4 3 Type SS and was wondering what are some good upgrades and/or replacment parts the I should buy when I first get it? I only have about $70-$80 to spend on extras.

[Scott S]

I've got an Evo and love it. I ported the motor and threw a paris pipe on it with the optional red clutch bell gears and the thing came aliveeee. My car is pretty insane, so I'd suggest getting a nice tuned pipe and the optional red clutch bell gears. These mods will really make the thing fly. I've also added the carbon fiber top deck for added rigidity which made it handle much more consistently. A fairly cheap upgrade is a set of tuned springs which will give it more traction and better handling then the stock hard black springs. Springs also give the car a splash of color.. :p And if you have any money left over, get a better set of tires, since the stock x-patterns barely have any traction to keep it controllable during acceleration.

Hope that helped! :D

word to the wise the ss does not have radio gear (you may know this already)
my first suggestion would be get a set of foam tires and threaded shocks. also how are you going to drive the car? just to drive in the "driveway" or do you plan to race?

[JDuncan]

I am going to doing mostly parking lot driving but I am going to start racing in a couple of months. What would be some good upgrades to start racing?

[JDuncan]

*I am hopefully going to start racing I don't know for sure, but I will be doing a lot of parking lot driving*

[chevy_94]

Scott that helps alot i owned one hpi which was a hpi RS4 RTR 3 that car kinda sucked because the front dog bones kept popping out from the inside of the tire when i took a hard turn but other than that i kinda liked it.but i see HPI really has only a 1/10 scale that has a shaft drive which i love cause im just afraid of belt drives. and i also thought about buying a Super nitro car but it is belt driven. I have a t-maxx that im trying to fix up now and i got it two weeks ago and that thing is sweet couldn't have asked for a better truck.
thanx for all the advice

[xkylar]

If you're planning on racing in the near future then you should just invest your money into getting an R40. I own both R40 and RS4 3. It'll take alot of money to get the RS4 3 race ready and before you know it, you could've bought 3-4 R40's already (just ask Kronic, he should know). The R40 is already solid out of the box.
Don't get me wrong, the RS4 3 is a good car (I upgraded the engine to a Fantom FR15 03). But it was made for street racing/bashing rather than dedicated racing. You can still bash around with the R40 as long as the parking lot is clean...

[Kenny T]

As the others above have said, If you are going to race invest in a race bred car from the beginning. I had both but I traded the R40 because I didn't need it, I wasn't going to race and if I do decide to race, it'll be once every 2 months and my SS is good enough for that.

They're both good cars but they were made for different purposes.

[KronicRacer]

yea i gave him the rundown last night... :p r40 would be great but its not parking lot friendly. so i pointed him to the ntc3 rtr. MUCH cheaper to get this car race ready(unless you want eye candy). :D

[chevy_94]

thanx kronicracer for pointin me to that NTC3 I didn't even think about team associated havin on-road cars cause i thought of them like having the monster GT truck and the RC10GT but not on road. that'll also be good cause my LHS carries Team Associated. thanx for the help. ill have that car in prolly a month cause i have to get my real one a new audio system.

[seven2xp]

hi, i have a ss with paris pipe and motor saver air filter.
the car is fast but i dont have good handling.
i only drive it on parking lots, with dust and dirt so it spins out alot.
seems to be oversteer.
under acceleration back end whips around to front
i am using the stock tires and wheels.
stock shocks
should i switch to foams
and stiffer front springs?

Stiffer front springs or weaker rear or a combination. Get some Proline V-rage tires all round. Increase the toe in the rear. All that should help.

Or you could just learn to control the oversteer and drift. :)

[TJNMT]

hi, i have a ss with paris pipe and motor saver air filter.
the car is fast but i dont have good handling.
i only drive it on parking lots, with dust and dirt so it spins out alot.
seems to be oversteer.
under acceleration back end whips around to front
i am using the stock tires and wheels.
stock shocks
should i switch to foams
and stiffer front springs?


Take Kennys advice also stay from the foams unless you are at the track or a truly finsihed parking lot with no rocks but a very smooth surface. If you run your foams in the parking you can kiss them good bye in about 5 minutes chucks will start flying off.

[KronicRacer]

nothing worse than running hpi xpatterens on dirty tarmac. no grip at all literally end up doing dounuts with them. also there is a thing where the car is up too high... you need the super chassisto correct it and the screws that are for the front knuckles (you need four more additional). the screws go into the a arms. with those things you will be able to i) lower the car ii) take away the massive cg from the ride height that nitro 3 has in stock form. in addition to the harder springs in front(put in bigger c clips for the tighter harder shock), softer (no clips) in the rear should help you alot more with hooking up and tire wear.

i havent had that much of a problem with chunks flying off of foams on unprepared surfaces :eek: . then again its relativly smooth, usually clean and the ride height has helped alot.

stick with the vrage rubber tires for now.

[seven2xp]

v rage tires are what i will get.
i changed the back shock springs to white
kept front black.
35 wt oil in rear 45 wt oil in front.
2 degree toe in back
much better now thank you.

new problem
inside edge of all tires have a wear spot that looks like the rim
made it wear out(uneven tire wear) is this just normal?

what inserts should i get with the v-rage tires?

[TJNMT]

check your camber, also are you using stock foams inside these tires?

[seven2xp]

yes stock tires with stock foams.
i need new setup.
i was told to get v-rage tires so i will try the s2 compond.
but what inserts are good?
they come with the tires but i heard that the foams that come with tires are no good.

i only drive in parking lots that are unprepared(dusy,dirty,pebbles)

thanks for the help everyone.

[KronicRacer]

basically if the inside is wearing the camber is negative. camber is very good to have. but if you have too much the inside is going to eat away pretty fast. you can correct this if you dont want it the negative camber does aides in turning.

[HPI-Fan-4-Ever]

Kronic is right, camber is very good to have, but not too much. Basically you wouldn't want more than 1 to 1.5 degrees in the rear and the front. Also try out 2 degrees in the front to see how well that works. Keep in mind that you will almost never use positive camber.

Most LeMans racers and JGTC cars have 1.5-2 degrees in front and 1 degree in rear (negative), but there is a lot more weight being transferred from side to side; if your car seems to "roll" more and has a higher ride height, then you typically want a little more camber for turning, since it will have more weight transfer and a high CG causing the car to tilt more than "race" set-up cars.........sorry if this is confusing! This is the best that I can explain it.

[TJNMT]

Just get the HPI med foams for bashing. The best tires I have used for parking lot bashing on the evo would have to be the 33r with hard foams, Super long life and the best I have seen run the same setup on my super but on the track it's different for me.

Also if you got 1 piece turnbuckles on the Evo get the adjustable ones, as for me I'm not too hard core and got the HPI ones. there like 9 bucks for the complete set, that why you can adjust your camber to get even tire wear

[KronicRacer]

i think its kinda messed up that hpi didnt offer the type ss adjustable turnbuckles with the evo. they should have :(

[hotbunz]

do boost bottles make a big difference?

[Kenny T]

No, some say almost none.

[TJNMT]

nope, just a bling bling if you want to call it that

[KronicRacer]

boost bottles dont add power, they do however help stabilize the motor when its suddenly come off of w.o.t. it sends all the extra pressure to the bottle and makes the motor return to idle faster. with out the boost bottle it takes a while for it to go back to normal idle. :cool:
most of the fantom 03 motors come equipped with them stock. if for some reason you dont want it you can take it off.

word of advice, dont install it if you have to drill the case every single engine block is built is built to spec. leave that to the pros, there is too much that can go wrong in unskilled hands. :eek:

[hotbunz]

i just bought new pinion gears for my nitro rs4 ss and i cant get the stock ones off. can anyone gimme some tips on how to get them off

[Scott S]

Unscrew with a rag around the gears and some pliers. They'll spin right off once you get em loosened up.

[Viper17]

Any one know were I could get aluminum spur gears for my rs4 3's 2 speed tranny?

[HPI-Fan-4-Ever]

aluminum would be noisy, and possibly weaker than you think....spurs are the big ones correct?

[hotbunz]

thnx for the tip scott but the pinion gears still wont come off. anyone every have this problem before?

[TJNMT]

Nevered had a problem, but I did I would try some heat on them gears

[HPI-Fan-4-Ever]

i started up my car yesterday, and i wanted to get it re-tuned since i bought a new clutch...it had a little trouble starting, so I opened the carb to about 1.5 mm and it started up, but when I adjusted it back to 1 mm the engine stalled, and it was sudden, not like it was slowly dying...I also reset the fuel mixture needle to about 2.5 turns out...whats up with that? I still need to adjust the clutch but I don't think that would be a problem...help me plz!

[KronicRacer]

fr15 right? whens the last time you put in a new glow plug?

new clutch, new fuel settings, new plug = one hella motor :eek: .

[vic2367]

hi everyone...does anyone know a good replacement engine for the hpi rs4 evo ?looking for more speed than stock ....

[HPI-Fan-4-Ever]

doh! i suppose i shoulda checked that...but the engine was relatively easy to start, i guess that's why i didn't think of that, thanks! :rolleyes:

[ALJR]

i just fitted this body to my type ss.. hope the pics works..

[ALJR]

here are some more pics of that body.. its a racers edge body (from tower)that i originally purchased for my NTC3, but it fit the type ss better..

[ALJR]

BTW, those are 30mm rear foam tires w/ 0-off set.. here is another shot.

[ALJR]

the suspension has been droped for the pics.. its not run at that height on the road..

this is a pic of whats under the hood..

[Kenny T]

Is that an alu steering kit I see? Do they perform any different to the normal plastic thingos?

Looks good, what chassis is that?

[ALJR]

Is that an alu steering kit I see? Do they perform any different to the normal plastic thingos?

Looks good, what chassis is that?

yes, its aluminum.. i got if from GPM.. it removed quite a bit of slop from the steering because it has ball bearings in it for smooth swing.. the front c-hubs are also gpm.. they too have ball bearings for the king-pin screws (the screws that secure the steering knuckle on). that also redused slop! i kept the plastic knuckles so other parts wouldn't bend (something gotta give, would rather it be a cheap plastic part)...

[HPI-Fan-4-Ever]

omg! thank you, i have been looking for a "1/8th body" for quite a while....it looks real nice.....can you do me a favor and post a link to where you found it at tower? i have been there before and i had trouble navigating and finding some thigns....thanks

[ALJR]

here ya go! gotta love the price too:)

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCSN8&P=ML

[Viper17]

ALJR can you post a link to were you got the alum. steering kit :)

[Viper17]

Here is a pic of my rs43 rtr without radio tray. Its got a Epic .18 motor, two speed tranny and alum. arms. I also removed the anodize on the chasis

[Viper17]

Here is a pic of my first body it is kinda old. I had this body for almost a year now and haven't gotten around to painting a new one. sorry if the pics a blury my camera sucks

[HPI-Fan-4-Ever]

hey ALJR, is the stock number on the body LXCSN8? i see the price and i like it :) but i don't know if the box on the side is for that particular body...thanks for the link!

[ALJR]

hey ALJR, is the stock number on the body LXCSN8? i see the price and i like it :) but i don't know if the box on the side is for that particular body...thanks for the link!

that stock number is towers! the number above it is the manufacturers.. if there the correct ones or not, ya got me. but i can say is i bought mine from tower, right from that link i posted. so my guess is its the correct numbers :confused:

[jerseyevo]

Why Are The Rear Wheels Angled Om My Rs4 Evo?

[Kenny T]

That's called toe-in. Basically it gives the rear end more grip.

[jerseyevo]

oh i see!
i just thought something was wrong because the rear wheels are pointing inward.
should i leave it alone?

[KronicRacer]

for the time being leave it like that.

viper17 that almost looks like a paint job i did a while back except mine was silver in front red in the back.

[jerseyevo]

Will The Wheels And Tires From The Super Nitro Fit My Rs4 Evo?

[Qube]

For those with the RS4 RTR3 EVO, how many turns do you have your two speed set at? I'm pulling my hair out trying to find where it doesn't get stuck in second or first... :rolleyes:

[HPI-Fan-4-Ever]

a simple solution would be to lean out your engine maybe like 1/4th a turn, then adjust the 2spd to engage at a higher rpm, but just a little tiny adjustment....usually it gets stuck because it engages at too low of rpm or too high....try this first before you reset, once you can get it shifting again then work from there, much easier than having to start all over again

[TJNMT]

Will The Wheels And Tires From The Super Nitro Fit My Rs4 Evo?

Yes they will fit and also rub. If all you want is for the looks, then it's all game

[HaCo]

Hi,

I'm considering to buy a Nitro On Road car. I'm quite new to Nitro (but I drive electric cars for 7 years now) but I think I'm gonna buy a HPI, because I like HPI just as a brand, it's not too expensive and it has a good quality (like my micro for example).

I want to use the car to drive around on parkings and maybe very occasionaly also on a track. For that reason I think the R40 is not a good choise for me, it is too expensive anyway. For me the choise will be between the SS or the EVO.

Now, as I live in Europe u should know that the SS is not equiped with a motor here, it goes for 239eur, it hasn't got a body either(http://www.hpieurope.com/kits/main.php?lang=en&partNo=441). The Evo 3 (not RTR) goes for 369eur, for that price a body and the T-15 engine are included.
I know LRP has an engine (Z.15 S PULLSTART) with pull-starter for 99eur (http://www.lrp-electronic.de/e/products/nitros/nitros_e.htm), so with a body (30eur) the SS in total would come for 368eur.

Now, my question to u is, what has the SS more (or less) than the EVO? It has steel turnbuckels I know, and for the rest... ? And how are the specs of the T-15 HPI engine compared to the Z.15 S LRP engine? I can't find the T-15 specs on the net anywhere. Do u maybe have some other advice on the car(s)? Or maybe a better motor for the SS? Keep in mind that not all products of the US are easy to find here in Europe. Oh yeah, and does just every .15 nitro motor fit, or do u need special adapters?

Thanks in advance! :rolleyes:

[Viper17]

Finally got my rs4 3 back together hope to drive it tomorrow. Here are some pics. :)

[Viper17]

Another pic.

[Viper17]

Does any one know were I could get some carbon fiber parts for my rs4 3? Im going to make it aluminum and carbon fiber, and Im making an intake that will sit in the cut in my front bumper.

[Kenny T]

HaCo, that LRP engine looks good to me, better than the T-15 IMO. Go for the SS with the LRP engine. You can drop any 12 or 15 size motor in the RS4 3, no adapters are needed.

Viper, I'm sure tower would have some hop ups for the RS4 3 or buy direct from HPI (BuyHPI). BTW, that's the weirdest exhaust I've ever seen.

[KronicRacer]

Does any one know were I could get some carbon fiber parts for my rs4 3? Im going to make it aluminum and carbon fiber, and Im making an intake that will sit in the cut in my front bumper.

go to www.meganitro.com they have cf upperdeck. cf shock towers, and cf front bumper brace. they also have a new 4mm chassis you should look at :cool:

[Viper17]

Kenny T, I made the exhaust my self out of copper pipe and painted it pearl black just for pics and to show off. I dont run my car with it because it is way too loud and it make my engine run funny when it is on. Thanks for the link Kronic :)

[Maseeh]

I just bought a Rs4 3 evo from a seller. He is a pretty cool guy, Shipped it out express without me even paying for it up front, He wants the money after I see it and all.
Only half a gallon run through it
What Can I expect? Any upgrades? Is it pretty durable, And how about some tips?

[HPI-Fan-4-Ever]

anyone been over and checked out the "world's fastest r/c" thread? i'm gonna take my dual engine rs4 3 there :rolleyes: hehehe that would be so cool

hpi's proceed placed 3rd in the 2004 winter nats this year, i think thats quite impressive given the release of the new serpent and stuff...go hpi!

[Maseeh]

I will be participating in that event, Entering the bone stock evo
I know it is not going to win any awards, But someone recommended it would be a good idea to promote Hpi, To show just how fast the evo is.

[Qube]

How many turns do you have your two speed out at?
Do you notice a distinct shift sound when running?

I ask because although the car has crisp acceleration and can hit just above 40mph (15% nitro), I can't hear it shift. This is my fourth touring with two speed and all the former ones have a noticable shift point sound. I can hear the telltale 'click' if I rev with the wheels off the ground, but on-road I can't find the shift point. So, back to my questions above...

[HPI-Fan-4-Ever]

sorry i can't tell ya my 2spd adjustment because honestly i don't know, but you can hear it shift when driving it, its sorta a "click" noise like you said you can hear, mine reminds me of someone pulling a zipper extremely fast, only more high pitched....hope this helps :eek:

[Qube]

I hear a very faint click, but there isn't a noticeable RPM drop sound. Perhaps the gear ratios here are closer than most stock 2 speeds?

[Kenny T]

I didn't know my 2 speed was even working until a friend told me. The engine revs don't drop a lot on my SS, I find it very hard to pick up the noise.

[shep]

Any one interested in a hpi rs4 ss3 it is for sale on the for sale page. It has a orion wasp .12 turbo all aluminum with carbon tons of extra parts from a-arms to gears, wheel, tires, springs. car is very fast just getting out of the hobby. $275.00

[HPI-Fan-4-Ever]

that's how mine is, you can hear it but the rpm's barely, if at all, drop

[hotbunz]

can anyone help me... i just bought a new muffler for my car n ever since then everytime i hit full throttle the engine just dies.

[Viper17]

Did you try retuning the motor. Correct me if im wrong but it sounds like mabey your running to rich. Hope this helps

[hotbunz]

i did try it but mayb im tunning it wrong

[TJNMT]

Does anybody make a lightweight upper deck for the EVO?

[KronicRacer]

Kenny T, I made the exhaust my self out of copper pipe and painted it pearl black just for pics and to show off. I dont run my car with it because it is way too loud and it make my engine run funny when it is on. Thanks for the link Kronic :)

thats pretty cool you did that with the copper pipe. i used 2 copper elbows to fit my ace outlaw pipe on the rear exhaust setup on my ntc3.


TJNMT

www.meganitro.com sells a carbon graphite carbon fiber upperdeck

[Viper17]

Yea that exhaust pipe I made makes the car sound like an Indy race car. Speaking of exhaust I need a new pipe and was wondering what you guys run on yours RS4s. I had a pipe for high speed but had no where big enough to get it to top speed so Im looking for a pipe more for acceleration.

[HPI-Fan-4-Ever]

Viper,
I have a Dynamite 2pc tuned pipe, the whole pipe is a metallic blue, I'm sure you could recognize it, sorry I can't give you any part #'s or anything. But the pipe definitely helped my acceleration.

If I wanted my car to drift, on what tires would I put duct tape or whatever on? It looks like its startin to rain, could be fun later on :D

[Viper17]

I have seen alot of people put PVC pipe on there rims for drifting. I might just try it myself but im am haveing major engine troubles. It was running a little too rich so I tried to retune it but I'm not very good at that and I think I leaned out the motor too much and blew it. When I went to start it it made a bad clanking sound :mad: and think it is time to look for a new motor. I was thinking about getting the new T-15 ($110) from HPI or the .18SS ($239) from HPI. Anyone have an 18SS??

[HPI-Fan-4-Ever]

:eek: i don't have any pvc pipe anyhow....i'll try some wide zip-ties around the tires and see how that works.....

i'd go with the T-15 if you're not as capable as others on tuning engines (no offense, i didn't know how to put it)...it's not a powerhouse but it's fairly easy to tune and reliable...i plan on getting the 18SS, 60mph in my car! :D

[Kenny T]

PVC is so easy, you'll get asideways a lot but it's not responsive at all, you won't be able to do precision drifts where you get within about half an inch away from a wall.

Also it's very fussy about surface, the smallest bump will upset the drift.

[Viper17]

Itsn't there a company that makes tires specially for drifting?

[burning perform]

well guys, i have a set of stock tires that came with my rs4 3. i wore them out pretty well, and when i run on my street it will slide and drift pretty well, considering that there is a small amount of loose gravel on the ground. Then when i use my good v-tread racing tires, i dont slip or slide at all. :D . this will be cheaper and most people have a pair of completely worn out tires they dont want.

[Viper17]

Turns out my motor was just fine and that clanking noise was the one way bearing for the pull start but now whenever I hit full throttle my car pulls to one side. I double checked the length of the shocks and they are fine and think that the chasis might be "tweaked" or bent but I can't tell. Is there an easy way to figure this out? If I have to I'll but the 4mm chasis from hot bodies for my car.

[HPI-Fan-4-Ever]

Viper,

one thing you can do is rebuild the shocks, although it is a pain in the butt...if you still have the stock shock bodies and fluid, one or two of em may have leaked causing it to lean at high speeds.....also check the toe-in/toe-out of your tires and make sure that one side has the same degrees of toe as the other...if you have 2 degrees of toe-out on one side but only 1 degree on the other this will definitely pull the car to one side.....take your time if you redo the shocks, but that is most likely the problem, unless you recently had a violent wreck, which would guarentee a bent chassis......

sorry that's so lengthy but you should fix the problem by doin these things

[Viper17]

Thanks for the reply. I just rebuilt the shocks around the begining of spring and I'm pretty sure there are no leaks but I'll check any way and I know that the toe-in is the same on both sides but to double check wont hurt. I have been in some serious crashes but I wouldn't think any of them would have bent my chasis. Now that I think of it some of the crashes I've had were very bad :D and I think it would be a good thing if I got a new chasis and aluminum shocks. They will be the first parts for my all aluminum/carbon fiber RS4 3. Thanks again HPI-Fan :)

[Viper17]

One more question for today, how would I remove the anodize from my alum. suspenion arms. I've heard of people using oven cleaner :confused: but I'm not sure. Thanks for all your help

[HPI-Fan-4-Ever]

if your crashes are as bad as you are saying, then your chassis is most definitly bent. even the slightest little bend offsets everything around it. if you don't already have one, a setup board will help determine toe, or you can measure your turnbuckles extremely precisely too. glad i could help

i need to know how to remove anodize too :eek: my stock chassis has more silver scratches on it than it does purple plating.......

[Kenny T]

Yokomo makes tires "drift tires" but people say it's just a bit better than using ABS on the tires. I use electrical tape on the tires, about 10 layers on each tire. The tape goes on the outside of the front wheels and in the middle on the rears. -4 degrees of camber on the front, 0 in back.

To get anodizing off, http://www.projecttwin.com/strip1body.htm

[KronicRacer]

i did my anodizing removal the hard way, hand sanding. also if you guys want to get the aluminum shiny get this stuff called flitz it aluminum polish and it works great.

[KronicRacer]

Turns out my motor was just fine and that clanking noise was the one way bearing for the pull start but now whenever I hit full throttle my car pulls to one side. I double checked the length of the shocks and they are fine and think that the chasis might be "tweaked" or bent but I can't tell. Is there an easy way to figure this out? If I have to I'll but the 4mm chasis from hot bodies for my car.


take the wheels off. then find a nice flat surface and place the chassis on it the chassis should rest nice and flat against the surface. if it doesnt the chassis is tweaked.

my recommendations for a new chassis would be the w.p.r. chassis, hotbodies 4mm chassis, or the hpi super chassis. i would stayaway from the aluminum arms over priced and completly usless (unless you only use them for show purposes) youre better off running the plastic arms when you do run. if they break they are cheaper to relplace.

[HPI-Fan-4-Ever]

i was runnin the car earlier, and when i turned hard then stomped on the gas (or pulled on the gas? :confused: ) the engine would rev up quickly then sorta "blip" like it was dying, so I'd have to let off the gas to keep it going....why does it do that? it does this sometimes when i accelerate to top speed really quick also...i'm thinkin its my 2spd, i just adjusted it, but i'm not sure

if you have an 03 Fantom FR15, what plug do you use? i recently started using an OS 8 short thread plug and i got the car to start with 1 pull, beautiful :)

[KronicRacer]

os max a5, since you are running an #8 you can lean it out a bit more since this plug is cool. os max heat range of the plugs (cold to hot: A3 #8 A5 r5) tune according to the plug. what it sounds like is, when you reaching top speed youre too rich. as long as you see plenty of smoke coming from the muffler and it sounds crisp and is responsive you should be fine. make a note of engine sounds and smoke thickness its not always about the heat. dont get me wrong on the heat thing because its very important not to breakthe 280+ deg mark. :cool:

[jerseyevo]

well 2 months ago i purchased a rs4 evo (also a savage owner)and when i got it i thought it was the greatest thing,it was everything i expected then one day my freind shows up with the ofna ld3,i was in awe when looking it over and could not believe the quality in this rtr kit with all these features and factory hopups costing less than the rs4!
well he let me drive it and that sold me, i immediately ordered one through tower hobbies and my rs4 has been sitting ever since.
only wish hpi would put out a higher quality product without needing upgrades.
if you do the research on these two cars you will understand what im talking about.

[HPI-Fan-4-Ever]

the car seemed really responsive, and there was smoke up until about top speed...when i brought the car in it was really hot too, i could tell hotter than normal...i thought maybe i was running it too lean cuz at top end its like it runs outta gas because of all the air coming in...i'll try leanin it a little bit...

thanks for the information about the plugs, i had know clue mine was a cool plug...i think that's the problem, it was still rich from the other plug and i didn't retune for the new plug, thanks a bunch

[Kenny T]

LD3 RTR 2 speed failsafe?

I was thinking about a LD3 Pro but I ended up with an R40:) and a well modded RS4 3. The RS4 3 RTR evo is fine if you're just planning on bashing but if you are planning on racing I'd get a LD3 Pro.

[jerseyevo]

this is my point...
why spend more for bashing when you can have a real race car for less money.

[HPI-Fan-4-Ever]

cuz most "real" race cars aren't meant for bashing or may be more than some "bashers" care to handle or maintain

[jerseyevo]

the ld3 is a basher and a racer out of the box,the rs4 is not.
i have not worn, broke or replaced anything yet on the ofna,as for the hpi they are not getting anymore of my money as there cars are designed as money pits.

[HPI-Fan-4-Ever]

the reason most of the cars are designed as "money pits" is because when a new racer gets a car, they don't rush out and get brand new aftermarket parts...they practice with what they got....i had mine stock for a very long time and I never broke anything either.....then after awhile I wanted more performance, and some more aesthetic parts, so I put more money into it...just like a car in real life, you can drive it stock or put money into it to set it up how you want....the more options, the better, and the rs4 evo simply has more options than the ld3, thats why it seems they are "money pits", because people like to create something of their own, and set it up how they want....you couldn't do this with a mugen or a serpent or even the ld3, besides maybe some carbon fiber

[Kuya]

I have a little problem and any help would be apprieciated. I have an RS4 RTR3 for about a year now and never really had a problem that I couldn't remedy myself but this one just surfaced recently and I'm stumped.

I've always kept meticulous care of my car cleaning it and repairing any damage after almost every run. This engine problem is really twisting my brain. My 15FE has always run smoothly until now. Now when I start it, my car runs louder than usual and will not stand idle anymore. I've already rebuilt the engine and there is no wear or damage inside. I've adjusted the needle to the point where the car will sorta stand idle, but it then has a hard time "catching" itself when you accelerate (If you punch the throttle, the engine chokes). If I leave the needle where I've always had it, the car starts to roll away from me at a constant 5kmh Furthermore, when I hit my top speed (124kmh), the engines pitch is much higher than usual. As always, smoke appears when I hit top speed but the sound is freaking me out. It never hit that high a pitch before and now the car is like it's stuck on "turbo" or something, my brakes slow the car down but my braking distance has lengthened drastically (from top speed to stop, the car needs about 7 meters when it used to stop at 3 meters).

This is everything I have in my car which involves interaction with the engine:
-HPI Racing Clutch (2nd setting)
-HPI 2 Speed
-THS Tuned Pipe
-HPI Fiber Brake Disc
-Carbon Fibre Upper Deck

The engine is the RTR 15FE with 5.5mm Carburator with the carburator still at the standard 1mm opening setting and I'm using 20% fuel.

I've already:
-Rebuilt the engine
-Played/adjustedwith the carburator
-Played/adjusted with the needle
-Played/adjusted the Idle
-Tried it with a stock clutch

I've tried all the normal procedures for tuning but the engine seems like it's stuck. Do I really need to replace my engine or can it still be salvaged?

[Kuya]

Ok, I don't know the science behind it, but I was getting frustrated at my engine trouble and so i kicked my car. Not much kicked, but more of using my foot to shove the car across the floor into a wall. and after doing that, i tried my car and it went back to normal. No physical damage to the car, but the engine is fixed for some reason. My car has been acting up for 2 weeks now and I missed a race due to this problem and all my car needed was a good bash? Maybe the RC gods were smiling down on me or something...

[jerseyevo]

maybe you have a vacuum leak..
did you try to RTV the carb neck and backplate?

I am thinking about getting into nitro tourers and was wondering what all of you thought of the 3 type SS. I love kits. There is just something about building it yourself. Any ways what are your opinions on it or any other nitro tourer for under $325. Thanks in advance.

[HPI-Fan-4-Ever]

its a great car, easy for beginners but can be "fast and furious" for those willing to upgrade....get one, you certainly won't be dissapointed....

if you're still unsure, however, check out Team Associated's NTC3, it comes in RTR and 2 different kit versions....

but of course, I'll recommend the RS4

[KronicRacer]

Ok, I don't know the science behind it, but I was getting frustrated at my engine trouble and so i kicked my car. Not much kicked, but more of using my foot to shove the car across the floor into a wall. and after doing that, i tried my car and it went back to normal. No physical damage to the car, but the engine is fixed for some reason. My car has been acting up for 2 weeks now and I missed a race due to this problem and all my car needed was a good bash? Maybe the RC gods were smiling down on me or something...

high pitched sounds usually mean something is loose on the engine
3 areas that usually will come loose come to mind:
the heat sink head 4 screws
pullstart back plate 4 screws
exhaust header 2 screws

also remember to change header gaskets they have to be changed every so often. traxxas sells pretty good gaskets for the exhaust and so does hpi. check your local lhs for more gaskets.

remember the ss kit only comes with motor. you still need to get the radio equipment seperately. any other kit out there will not have a motor or radio. This is the one of the upsides about the HPI. :)

the fact that there are soooo many parts for it makes it easier to get parts for it if you do break it. this makes it easier on the pocket book and on the flip side is bad if you want to do ground up with top of the line parts. all the parts will add up to a big bill. :eek:

if this is you first time in nitro the hpi is a good car to consider.

the best thing to do is go with what the lhs carries most. dont go out and get the hpi if there is no support for it locally. online ordering gets old especially if youre racing or if you bashing and break something. its faster and easier to run or drive to the lhs to get the part than it is to wait for the mail man :cool: .

[HPI-Fan-4-Ever]

my back pull-starter plate is held on by 1 screw and 2 body pins lol...it won't budge a bit, either.....

It was a loose heat sink, thanks man. It was just what I needed.
It wasn't the header because the sound was not louder but a higher pitch.

I was playing around with my car today in a big empty parking lot when all of a sudden, a cop car pulled up. I thought I was going to get a warning or something about sound pollution but he was just interested in my car. I was telling him how fast it goes and he didn't believe me so he pulled out his radar gun and we tested it. When he saw the numbers (132kmh), he believed me and asked where he could get one. Naturally, I gave him directions to my local hobby store and told him the brand name: HPI

[andrew23mj]

Thanks a lot guys. I think that I will probably get the SS in a few weeks. I already have a radio so a rtr is almost a waste with getting another radio. HPI Fan 4 Ever thanks too. I am going to look at the NTC3 a little more since I already have the electric TC3. I'll post some pics of whatever i end up getting.

You would not be dissapointed with the Ntc3 its a beauty of a car. there are 3 bad things. 1 is the shock towers the tend to twist and snap off the diffcase when a wreck occurs. this renders the case and tower useless. they have come out with the fix to correct this. the only thing is they are hard to come by. 2 with the standard kit; the rear turnbuckels have been known to pop off out of position with a hard knock. 3 with the factory team revision that just came out they have put the rear shock tower in a breakable position again. you can not use the fix on the v2 rear suspension. the fix is usable for the front only on the FTNTC3... i guess that the price you pay for adjustability. if you learn to keep off of the walls you should have no problems with the ntc3 :cool:

[ALJR]

the ntc3 is a grat car, it is far superiour to the type ss on the track. but be warned, it is not a basher! i own both cars and there both great. the ntc3 can't take a hit too well, but it will out handle a stock hpi.. on the other hand, the hpi will smack curbs, flips, crashes all day long and keep on ticking.. of course that may be a lil exageration, but the hpi is one tuff car.. it will cost you quite a bit to get the type ss upto track compeating specs... but then again, isn't that half the fun of this hobby? to customize our cars:)

[jerseyevo]

anyone try the new venom tires on there rs4?

[ALJR]

im using the joco nitro shoes and im very happy with them.. running 30mm 35 shore in the rear and 28mm 45 shore in the front...

[Viper17]

What will a one way front diff do for my rtr3 and is the hot bodies 4mm chasis any good or should i go with the HPI super chasis.

[Kenny T]

Either of those chassis are good. With a one way you lose front brakes but it locks as you're accelerating, it pulls the car out of the corner. It might give you better lap times, depends on the driver and track I guess.

[ALJR]

the hpi super chassis is way better! its made from stiffer 7075 aluminum. where as the hb chassis is softer 6065 material

[KronicRacer]

with the super chassis you can now set the ride height lower. which is better for handling and CG. you have to have the plastic suspension (stock) arms to be able to do this.

[jerseyevo]

[Viper17]

Thanks for the replies. I am going to go with the super chasis. I just thought that the hb chasis might be better because it's 4mm thick. :)

[TJNMT]

Looking at getting some non-pull start engine mounts for my evo. I really don't want to cough up the dough for the HPI ones. So far I have been using the the cheap o blocks with my engines while using the starter box. Sucks I now.

Does anybody else make mounts for the evo. I know gs racing has some adjustable ones, wondering if those would fit, also wolfpack does for sure.

Any replies would be helpful
thank you

[HaCo]

Hi,

Just got my EVO today, I ordered it with some HPI foam tires, front 26mm width, rear 30mm width.

The rear left foam tire slips to radiobox, anyone got a solution for that? In front it also slips a litle to the e-clips of the front suspension, anyone solution for that?

I am also looking for an image of the Nitro 3 mounted with a carbon upperdeck, fully equiped with and without radio gear.

Thanx in advance.

are you planning on a non pullstart motor? sounds like you are since youre using a box. with the wolfpack radicalsadjustable lower mounts the stock flywheel will stick out of the bottom of the car. so you need a smaller flywheel, which i think hpi carries.

ill post a pic of my car later. what foams did you get? usually ive had the front rub with elligi foams.

for the rear tire rub:
1 upgrading to the carbon upperdeck
2 grind down the stock radio tray where the tire rubs
3 or get jaco shoes. 26mm front/30mm rears with 2 degree offset

I all ready am using a starter box, Currently what sits inside the evo is a Fanotm.12 with a RPM lightwieght flywheel non pull start. So I should be ok. I emailed wolfpack to make sure as well

[KronicRacer]

you should be set then the wolfpack mounts will fit with the smaller flywheel

[jerseyevo]

i have a brand new rotostart and backplate for the rs4 evo if anybody is interested make offer or trade.
(does not include battery or oneway bearing).
i removed it from my evo and installed a recoil starter when i purchased it..
email me at gg32@optonline.net

[HaCo]

KronicRace: well the foams from HPI, for the R40. 40 at rear and 45 in front. I now use an M4 washer between the wheels and the hex-adapters. I still stay (way) under 200mm width.

I'm looking forward to the pic of your car.

here it is

VERY nice! Lots of hopups. Finally got my EVO running today. Afther breaking in the engine I am now trying faster and faster. Man, the car is a SPEED monster, the street is too small for it, but I LOVE IT! You can hear the car shifting in second gear, a thing that I like :)

My next hop ups:
- Titanium Turnbuckels
- Carbon upper deck
- CVD cardans
- Alu Steering parts

[HPI-Fan-4-Ever]

Kronic,

What kind of pipe do you have? It looks like a custom one.....

and whats a very cheap 5-cell pack i could get? the connector on the one i have came off somehow and now the pack won't transfer power......

[KronicRacer]

the pipe is from ace racing.

try www.onlybatterypacks.com , i use thier 5 cell flat packs on my electric m18 when im not using them on my nitro recievers for r40 and ntc3. im using humpstyle for the nitro 3.

[HPI-Fan-4-Ever]

awesome that's just the thing i was looking for, i bought a 5-cell pack designed for the micro and i was really upset that it decided to break cuz it cost me around $40 :mad: :mad: :mad:

[HaCo]

Can't u just solder on a new plug for transfering power? Seems cheaper to me :)

[HPI-Fan-4-Ever]

uh...umm...maybe :) i never really thought of that, i suppose I could, but i've never soldered before in my life, and i certainly don't trust my stepdad at doing it...besides those packs are only 15 bucks.....

[Fat_Bastard]

Which MIP CVD's go into the RS4 3 SS? I believe that it is the wide but I want confirmation.

[KronicRacer]

uh...umm...maybe :) i never really thought of that, i suppose I could, but i've never soldered before in my life, and i certainly don't trust my stepdad at doing it...besides those packs are only 15 bucks.....


you gotta be carefull with it because if the sodder heats up the battery you could damage it. take the safe route and get a new one.

FB

sorry man, dont have an answer to that. the only cvds ive used for this car are the hotbodies ones....

[jerseyevo]

its attached to the inside of rollbar.

[KronicRacer]

thats for the pullstart keeps it in the standing position

[vtecpower]

I recently bought RTR EVO. I didnt' like the rotostart so i bought a pull starter to replace it. the pull starter bought was for the FE i think, the bearing on the t-15 is 14mm while the bearing on the FE is 14.5mm. would using the pull starter from the FE mess up my t-15? it starts and every thing.

if the oneways catches the crank like it should without slipping on a pull there should be no problem. this shouldnt happen anyway since the pullstart hpi has is universal . it wont damage the motor in anyway. :cool:

[Viper17]

What starter box could I use for my rs4 3 that isn't to much money and will start my epic .18

[HaCo]

Are there any afthermarket carbon fibre parts for the Nitro 3 and are they good? Where can I get them?

Also, on the HPI site they put a 5cell hump pack at the HopUps of the Nitro 3. Has anyone got ANY idea how u get them in the radio box??? Those are AA cells, or?

HaCo

[Viper17]

I know that Hpt Bodies used to make cf parts for the rs4 3 but I think they discontinued them. Im not sure. This site has some parts www.meganitro.com

[KronicRacer]

hotbodies did discontinue :eek: the carbon parts :( . get the hpi carbon upgrades. you cant go wrong choosing either.

the best thing to do is use the 5 cell humppack with the carbon tray.

ive used the ae starterbox. when you start a bigger motor always make sure that the batteries are always charged especially if its a new motor that needs break in.

[Viper17]

Thanks Kronic. I know right now that my epic's compression is really low and it is time for a new piston and sleeve. Ill check out that ae starter box. Thanks again

[KronicRacer]

just remember the ntc3 box is different. its going to line up in reverse. ive just bee too lasy to find the apporpriate box for it.

[Kenny T]

Can I get a spool for the RS4 3 or do I have to lock the diffs myself?

[burning perform]

guys my engine is really screwed, at least my car is... I started my car up and it starts just fine. then i give it some throttle and notice that the pinion gear is turning but the wheels are not! so i kill the engine and realign the gears. i start the car again and the car starts up and i give it throttle and again it doesnt move. I give it half throttle at that point and the engine revs high and dies. I am clueless! could it be that some oil got inside the pinion gear and is making it slip at high rpm's? maybe my clutch is also oily? I think i remember my cars pinion gear eating my fuel line a while ago making a fuel spill so that could be the source of oil... but still im without any idea. thanks for the help

[Kenny T]

Does the spur turn? If it does then the diff gears (internal or external) could be stripped.

Are you running a 2 speed or just a single speed?

[burning perform]

yes I have a two speed tranny. the purple things are always spinnin so yeah i think somthin is stripped. excuse me for my lack of car terms, its just so early over here

:rolleyes: zzzzzzzzzzzzzzzzzzzzzzzzz

[Kenny T]

Do the spur gears turn?

[HPI-Fan-4-Ever]

well, if your pinion gears are turning, then the clutch is obviously engaging...so take the top off of the center bulkhead to reveal the 2 speed, you should be able to spin the first gear and make the wheels turn, and the 2nd gear should freely turn...

if your pinion gears are spinning as soon as the car is started, you need to lower the idle speed though they don't start turning until you give it throttle...although unlikely, this might cause part of the problem

also keep in mind that your pinion gears are supposed to freely turn a certain direction without causing the car to move......strip the tranny down is all i can tell you

[cudacharger]

I was wondering about the carb low and high needle settings on this car....all stock....broken in...but I'm having trouble starting the car after she has run for awhile.

The manuel say's three turns out for the high....but mentions nothing about the low setting.

Thanks in advnce!

[HPI-Fan-4-Ever]

you say you have trouble after "she" :p has been running for awhile...your not alone

after about 1/2 or more of a tank has ran through it, the compression goes waaay down because the heat of the combustion inside the engine causes the piston sleeve to expand, giving the piston more room to move.....if you wait about 15-20 minutes after running to try and start it up again, you'll find it much easier.....

....as for the low speed (aka idle), i always turn the servo as far back as it can go, tighten the idle screw all the way, then slowly loosen it until you have right around 1mm of open carb...you may have to adjust the servo so it pulls back on the carb to keep it closed.....

[M3EVOlution]

Can anyone please help me install a throttle arm and nut? How do you know when to screw on the throttle arm, when the carb is manually moving? BTW, i have an HPI RS4 3 EVO.

[cudacharger]

Thank HPI fan!

[M3EVOlution]

please help!!!

[M3EVOlution]

Here's a picture. How will I install the new arm with the carb freely open. Won't this mess up the idle adjustment because it isn't set to the factory adjustments. Please help me install this! :(
http://memimage.cardomain.com/member_images/1/web/481000-481999/481894_105_full.jpg

[M3EVOlution]

How should I align the carb?

[KronicRacer]

^^^^how did it run?

[M3EVOlution]

it didnt work i did what u told me and then when i hit the brake, the carb loses a lot.

[jerseyevo]

just set your radio to nuetral and remove the brass linkage nut,
slide on the new arm and tighten the brass nut where the throttle is closed.
from the radio side the carb linkage at full throttle should be at 10 o'clock and at closed should be at 2 o'clock.

[M3EVOlution]

what do u mean "when the throttle is closed?"

[jerseyevo]

look down the carb throat,it should be just about closed.. (where it would be at idle if engine was running and car not moving)

[kidd25]

hey all. i have a couple of questions maybe some one can help me out. Im in the process of tearing down my RS4 rtr3 and when i rebuild i plan replacing alot of the stock parts. the engine being one. will the epic .18 fit? i also plan on getting the super chasis. next qustion..will evo parts fit the old rtr3?one more thing since i plan on putting the bigger motor in what else do i need to replace? or add?
