you take the glow plug out

Even without the glow plug it won't move at all. :(

[Silent Night]

Try using a hair dryer or heat gun to heat it up a bit so the sleeve expands..

[josh222]

that is called pinch, my xs has so much my starterbox can't turn it over cold

[roehrig]

stick it in the microwave or pot of boiling water.... :eek: :p

[Silent Night]

lol.. just stick it in the oven for a little while.. and don't be stupid and try to take it out with your bare hand... use oven mitts...

[roehrig]

don't melt the plastic on the rest of the car either.... or start your tires on fire....

[Asmenoth]

Yeah...just put the engine in the oven to be safe.

:D

[roehrig]

but...but... but.... can't do that... cause by the time you get it back on the car it will will will be cold again...

have your dog sit on it.

[josh222]

just heat it up with a blow drier

[DraconicPenguin]

i think ill pass on the oven idea... ill heat the engine up with a blow drier tonight to see if i can get it to unstick. thanks for the help.

[Jetskiboy77]

I'm still having a lot of trouble with my 18SS. I went to try and start it again today and had no luck. After trying a bunch to get it to start, the pull starter locked up. The piston is stuck at top dead center. Turning the flywheel doesn't move it anymore either. I was following the instructions, I don't know why it got stuck. Is my engine screwed up or is this something I can fix? Help?

Ive had engines that had so much compression that it would get stuck at TDC also, so check for that and flooding.

[josh222]

are you talking about your XS?

[Jetskiboy77]

Yes, my .12R XS did it and so did my Hyper 21.

[josh222]

lol ya, mine is really tight :)

[DraconicPenguin]

ughh.. Heating it did fix the piston problem, but I still can't get it to start. I don't think it's flooded, the pull starter is pretty easy to pull. Glow starter is charged, tried a different glow plug, got the engine nice and hot with a hair drier, but still nothing. Should i take it to a hobby shop to see if they can get it to start?

[roehrig]

are the settings at default or did you change them?

[DraconicPenguin]

everything is default

[roehrig]

well... new engines are kinda a PITA....

gotta make sure they are getting enough fuel, but not so much it hydrolocks your pistons....

tweaking the low speed needle 1/4 - 1/2 either way sometimes help....

Does the engine at least sound like it is trying to start (a little grumble & popping) or just the usual pumping of the piston due to the pulling of the pullstart.

[roehrig]

Actually, I am in the same situation with the slide carb I put on my 18ss... it is set at defaults and the engine didn't start up... so I leaned a little bit and it at least started popping a bit on pulls.... so I know I am close to getting the correct fuel air mixture combo.... I just gotta tweak it a bit...

[DraconicPenguin]

When i try to start it, i just hear the piston pumping.

I'll might try messing with the low speed needle a bit, but I think i will go ask for some help at a hobby shop first. I don't want to get too far off from stock settings since im not entirely sure what i'm doing.

It's hard to tell when priming it where the fuel is because the tubing is so dark. That's probably half my problem, just not getting the fuel anywhere. Bah.. I hope i get it working soon..

[roehrig]

yah.. sounds like your on the right track.... have your hobby shop check it out... and get some clear fuel line or at least some you can see in....lol...

[josh222]

ya LHS are a good place to go

[azizhousecallz]

nitro 2 speed tranny. i keep burning up and melting down my 47 tooth spur.
i can run the car for about 10 minutes then it happens! it eats the teeth off the damn spur. first i thought it got wet because ive seen water eat the plastic spur before. but today in the dry sun it melted the teeth again after running for about 10 minutes. what im i doing wrong guys?

car: rs4 3 evo

[roehrig]

47 is the first gear right?

maybe the gears aren't meshing tight enough and the tips of the metal pinion gear is just eating off the points of the plastic spur

[CrankrodsKid]

One time I had the wrong clutch spring on my cen mt2, and the transmission kept getting hot, finally it just melted the gears lol.. is your car running ok? if not then maybe this is your problem...

[josh222]

bad gear mesh

[azizhousecallz]

thanks i did just take the engine off may not have lined the mesh up tight enough. i'll put the new gear on and check. thanks guys! just got my new rush evo today its breaking in right now. ! :D

[josh222]

if you can put a peice of paper in the gears and pull it out with out it ripping(gears have to move) it is set right

[F150RTR]

at last after long hours the vsm speedometer is on , actually all thanks go to roehrig who showed me where he installed his vsm, i have a hpi rs4 3 rtr. I also installed the exhaust manifold, and i did notice a difference with that installed.

[josh222]

cool

[roehrig]

Pain in the butt, isn't it?

[F150RTR]

holly smokes is it ever, at one point i was going to give up, now i have to take it out and see its top speed.

[josh222]

ya now if someone asks you can tell them

[Turbo B]

josh when do u start spring break.. cause i start mine next week and if its warm maybe we can bash around

[josh222]

i probly live to fare away and mine is all ready over :( i live in Canada but i am like 1 drive from Buffalo

[Turbo B]

o shitt wrong person sowwi.. the person his sn is jetboi or sumthing like that i was talkin bout lives in queens,ny

[Deznuts05]

Question guys... but how oily does your car get after playing for an hour? right now its a freakin mess... I'm using Trinity Monster 20% and its sick how dirty and oily eveything is... oh and I was in the 250-275 range heat wise... is that too hot/cool? thanks!

[roehrig]

I think that is too hot... 230-240 is safe....

[Deznuts05]

really... oops ok I'll try a lower'n the heat...

[josh222]

generaly 200-270F is the safe zone, i try and stay in the 220-260F range

[Deznuts05]

oh ok... how about the oil build up? like how oily does your cars get? (FE .15 w/ Trinity Monster Power 20% nitro)

[roehrig]

well.. gets a little oilly... oil on the engine.... dirt on the oil... makes it look more dirty...

maybe get one of the rubber exhaust extenders, if it bugs you that much.

[F150RTR]

roehrig is right get one of those exhaust rubber extenders and you will notice it get a LITTLE bit less messy, mine used to get oilly alot and now with the extender you notice some difference especially on the inside of the body.

So if someone is running high temps what do you do to lower it down a bit?

Josh222 i see that you are from Canada me too, is there a particullar place in Canada where you buy your stuff or do you mostly order from the States?

thanks

[Deznuts05]

"So if someone is running high temps what do you do to lower it down a bit?" run it rich... turn the high end needle counter clockwise... move it 1/16 at a time till it gets low enough

[josh222]

I buy major things from Tower or RCBOYZ, or things i get from my lhs called Action Hobbies in Brampton ontario

[F150RTR]

Thanks Deznuts05 and Josh222.

[josh222]

where do you live F150RTR?

[F150RTR]

Halifax , Nova Scotia

[F150RTR]

you'd think that a temp gun is important but thats one thing is still have to buy. :(

[josh222]

i use a onboard..

my family is froum near Sydney, my grandparents lve it north sydney :)

[roehrig]

well, i woouldn't have too much concern as long as you have a good trail of smoke coming out under full throttle.

[Deznuts05]

the temp is critical for the FE's... I had white smoke from day one on my last fe and it didn't last any more than 10tanks... this one I'm tryin to keep for atleast one season... cool is better... slower.. but atleast you can last the race

[Zoo Tv]

Well, can I post a few points about my 18SS kit I just took for a run today...

Firstly, one pooly moulded steering component meant I had to order replacement at my cost - HPI USA didn't want to help as I am in Australia. Quite poor really - but never the less this is a risk when ordering over the net.
Secondly, pull start quite poor - broke during first attempt to run in.

Now that it is run in - wow! What a quick car. Given I won't be racing it this has more speed than I'll need. Accelerates nicely - even better when the motor loosens up a bit more and the 2-speed is tuned for a better shifting point, good top end too.
Brakes need adjusting as with the hi-torque servo I am using on the throttle just locks them up. Will have to fiddle with the ABS function on transmitter.
Very reliable. Starts very easlily (use roto-start now), idles forever and FORD GT body looks amazing.

[josh222]

there pullstarts break easy, i recomend getting a starter box and port match the manifold

[MaNiac42]

pull starts breaks easily because you might pull it too far out, try pulling it out with about 1 foot, ( i start my RS4-3 with 2 or 3 shorts pulls and its starts quickly), but today when i was playing with my car, the starter broke but i fixed it :D

[josh222]

mine broke first pull and i was half way through the pull when it broke

[Hockeekidd98]

pull starts suck....
Get a roto start, or starter box

[MaNiac42]

is it ok if i ran an O.S. A3 Plug on my 15.FE

http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXCB26&P=V

[Jetskiboy77]

Yes, you should be fine with that plug.

[josh222]

is use McCoy MC59's

[F150RTR]

will this 2 speed { OFNA 35015 2-SPEED ** work on a hpi RS4 3 RTR?

thanks

[Jetskiboy77]

o shitt wrong person sowwi.. the person his sn is jetboi or sumthing like that i was talkin bout lives in queens,ny

Im guessing thats me since my name is something like "jetboi" and I live in Queens NY.

[MaNiac42]

so the plug will work with the 15.FE, wont it'll over heat?

[Turbo B]

Im guessing thats me since my name is something like "jetboi" and I live in Queens NY.


lol yea thinkin maybe we could get a few runs in

[envelope]

Okay, first let me say that I have a Ofna CD3 that has the same engine layout as HPI cars being on the right side. I was looking at the novarossi (black) 51603 and it looks like that and all their other pipes fit left side mounted engines :confused: Now I know that is just the pipe and I would have to buy the correct header/manifold (probaly get from ofna) but is it possible to turn the pipe so it will fit right? Like does the nipple on top have to be directly on top or can it be turned. Hope I explained this correctly. Thanks!

[Hockeekidd98]

why don't you post this in the ofna cd3 thread....

[josh222]

because the CD3 fourm is dead... and i was the one who said to look for exhaust for the rs4 3

Here are some very high quality setups by RD logics and THS Racing

for side exhaust.

Thanks Man!

[josh222]

no prblem, where here to help :)

[leoboy254]

well my stupid roto start backplate still has not come. IT'S BEEN TWO WEEKS. has anyone else had problem with rcboyz. also stupid usps they are so slow. i wanna run my rs4 3ss. it sucks, because i bought a fresh quart of nitro when the pull starter broke. i hope the nitro is still good

[roehrig]

well, I am selling off my RS4 type ss w/ 18ss stuff... going to get into trucks... either get an hpi MT 18ss or traxxas jato....

http://search.ebay.com/_W0QQsassZigottahelmet

It is a whole lot easier to run trucks here in hawaii than on-road cars..

I just checked it out and I was actually already watching that item because I wasnt sure if I really wanted a new car. The price is very tempting though, how good does it run? And, I good does the 12ss still run?

[roehrig]

the 18ss runs fine as well as the 12r.... i say about 8 tanks max thru the 12R and about the same for 18ss... i like the car..but there are not a lot of wide open smooth lots here....

actually the 18ss just cam back from hpi support..I was having problem getting it started..s.ent it in.. the checked it out, adjusted it and sent it back to me... started up right after that...

[envelope]

COOL! You might just be hearing from me in 3days 13hrs 57min....counting :D
For Real though, I am very interested. Anyway to get you to sell it right now for $150? Just asking :confused:

[josh222]

the SS is a good car and with that engine it will blow your CD3 away

[roehrig]

Nope... am a gambling man... will just let the auction ride...

[Deznuts05]

Hey guys, I have the stock Two speed installed on my RTR3 and I'm not sure if its working or not... What are the signs of that the gears are changing? like is there a sound that I can hear, maybe the rpms drop and then rebuild, or is there a dramatic visual sign that the car starts increasing in speed?

thanks... oh and like the carb is the 2 speed have any killer settings like 1/4 turn out from full lock? I'll be racing in a small tight track... So far I like the acceleration of the purple gears but I forget what color gears are the quickest in accleration... gold perhaps?

thanks in advance

[josh222]

you will hear it shift the Rpms drop and the car gets a bit snappy and speeds up fast.

for better accleration got for the gold gears

[Silent Night]

I;m not positive, but I think I might just have the fastest RS4-3 in a few days(speed, not handling..)... Its still being built but so far has a O.S .18 TZ, lower and harded diff gears, red pinion, gpm chassis, hotbodies upper deck, cf rear shock tower, racing clutch, 2-speed, fiber disk brakes, racing flywheel, and that about it i think... I still have my RD logics outlaw pipe that should be here tommorow... I'm still going to order 37/41 spur gears to lower the ratio even more, a yokomo lola style body, foams, front cf shock towers, graphite shocks, shiny cvd's, then get the engine tuned by the guy at rbmods :cool: ... I'm not trying to brag or anything but just a thought... I have no alumium upgrades besides the engine mounts (I wish they would come in cf :D ) to keep weight down... So, does this sound like a winning combo?

[Hockeekidd98]

I hope you have money for tires.

[Silent Night]

Yeah.......... :o

[Deznuts05]

thanks josh.. but how about the set screw setting? how many turns out from full lock

[josh222]

it is hard to say, it all depends of the engine and settings, you are going to have to figure it out your self :)

[Deznuts05]

ok thanks... now is there anything that I should know... like the first time I messed with the carbs I really screwed the o-ring or something... so is there anything that I should know?

[MaNiac42]

how much is a 2 speed for a RS4-3, i need one

[Deznuts05]

Maniac, check on ebay I got mine for $40 shipped

[MaNiac42]

alright, i'll check ebay out

[Zoo Tv]

The SS as in the 18SS? I have one of these. Engine still a little tight and only running on 16% but is hauling the mail allready.
Suspension (read shocks and settings) need some calibration though.

[josh222]

if you have the money get the wplfpackradicals 2-speed

[KronicRacer]

this ones for josh.......... after you showed me the mod you had done for you front suspension it was tooo trick not to do. bar none this is the best mod that i have seen for this car in terms of suspension tricks. im giving you major mad props for this one.... any whooo heres my version of it.

the problem that led up to this. front c hubs are floating on top and are not held by anything other than the camber tierod link. the solution making an upper adjustable a arm withot going overboard.
ive got aluminum componets on mine so i did not want to drill into the hub like in josh222's version
i put the ballstuds on the steering arm area like you did... the difference was where my placement would be on the c hubs.. i removed the top m8 bolt from the steering and put the ballstud there(after grinding down the spacer). i connected the two ballstuds with left over ntc3 v1 rear tierods (after dremmeling the ballcap ends for optimal suspension movement and good fit). and no i present the "final" product

http://img.photobucket.com/albums/v396/kronicracer/DSC00372.jpg

http://img.photobucket.com/albums/v396/kronicracer/DSC00361.jpg

the end result is that the c hubs now do not have any wiggle to them which leads to a more accurate castor setting, less chances of breakage, and overall a more accurate suspension.

and it looks totallly trick!

note
* i used shumacher ballcaps and ballstuds very low profie so the tires clearence do not create issues and there is optimal suspension travel.
*also used ofna aluminun hexadapters. (had to modify, minimal grinding for the wrist pin could go in more).
*used tire lock nuts from G4
*ntc3 rear tierods or 55mm in length.
*dremmel.

[RCNitroDude999]

does that make the handling any more stable?

[Asmenoth]

I have a problem, and several hundred posts to comb through. I have the RS4 3 SS. Going through HPI's site, I ran across a list of racing suggestions and I am down to the 2-speed. I changed it to 18/23 pinion and 39/43 spur...unfortunatly I can't seem to get them to mesh together. The 23 pinion sort of meshes with the 39 spur, but not enough. What gives? Any ideas, or should I go back to the stock set up?

:D

[Zoo Tv]

I am also trying to find a ratio chart from HPI but have been unsuccessful. I know there is a formula to work out theoretical top speed given final drive, pinion and spur and engine RPM, but does anyone know of a ratio chart?

[Asmenoth]

Not sure if this is it...

shoot me a list of all the parts id need to that to my car.. if u can thanx alot

[josh222]

ok, this is what you need..
Two 2turnbuckles about 60mm
4 ball ends with m3 thread
4ball cups

[Zoo Tv]

Me got another question Josh. What the widest rim/wheel we can run on an RS4?

[Hockeekidd98]

http://www.radiocontrolzone.com/cars/calculator.asp

[josh222]

he wasn't asking that..

generaly 26mm wide up front and around 30mm in the rear but you can go up to 35mm in the rear

[vegasdrift]

I've been looking at some nitro tourers and I saw the nitro 3 evo. I've actually had my eye on it for awhile. I just want to know how it stacks up against the other nitros(TC3 plus RTR, 4-tec, ofna cd3). I will be using it for weekend racing.
Thanks

[rshornet]

hi, I'm having problems with the lightweight flywheel. when I install it using the black collet the flywheel sticksout too much that the pinion fouls the spur gears. Which collet should I be using? Do I have to grind down the collet to get the neccessary alignment? any help would be great.

[Turbo B]

ok, this is what you need..
Two 2turnbuckles about 60mm
4 ball ends with m3 thread
4ball cups


how da hell will i mount it.. u kno im kinda slow when it comes 2 workin on dis car :(

[Hockeekidd98]

Look at the pictures, should be simple enough.

[josh222]

rshornet, i find when you put a flywheel on an engine that it won't go on the collet all the way and less you start tighing the pilot shaft onand it will pull the flywheel onto the collet.

Turbo B.. youreplace the steering posts screws with ba33and and put the other ball ends on the c-hub, then put the turn buckle on..

vegasdrift.. whenyou say weekend racing do you mean serious racing or the sport racing class? if you plan on racing the the big races, the EVo won't do so good with out some upgrades and it has a .15 which is not race legal. I think if you want a RS4 3 go for the Type SS, it is fast(about 50mph) has a .12 engine, 2-speed, adjustable turnbuckles and it go for 250 + 50 for radio and towerhobbies.comhas a 30dollar off coupon so you can get it for 270

[josh222]

RS4 3 With RSX body (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCFN9&P=7) $259.99

[F150RTR]

Hi everyone,

I have the HPI RS4 3 RTR, how far will the radio control that came with the car take the car in distance before i loose control(have a run away)...........battries new

an approx distance would be great
thanks

[Silent Night]

i donno... the farthest i've probally taken mine was maybe like 750-1000 feet..

[vegasdrift]

I'm not sure on the classes that my local club has but I'd probably race the sport class first than progress as I get better.
Would the ss be a good racer? for both the sport and higher classes when I get better.

[F150RTR]

anyone else knows the answer to my question?

thanks silent night

[josh222]

the Rs4 3 is a great car for the sport racing class, if you want a serious racer you are gona have to shell out some serious doh,


I rearly pass 400-500ft from my car because it is hard to see :rolleyes:

[Hockeekidd98]

Hi everyone,

Think of it this way, buy the time it goes out of range, you won't be able to see it..

[vegasdrift]

the Rs4 3 is a great car for the sport racing class, if you want a serious racer you are gona have to shell out some serious doh,
What do you mean by serious racer? National events or highest level weekend racing class. What do the pro race cars have that the rs4 3 doesn't?

[josh222]

well most pro cars are belt drive, pivot ball supention, have alot of carbon fibe and titanium, uses high quality parts, the Rs4 3 is fine for week end racing for fun, but the high level classes no rtr or artr car cut it

[josh222]

like this, the R40

[vegasdrift]

Does the r40 use rear exhaust engines? The only thing that's stopping me from looking at belt drive cars is belt maintenance. How do you maintain belts and how often does it need to be done?

[Jetskiboy77]

The R40 can only use rear exhaust engines. I think the RS4 3 is a great race car for fun and the weekend, and with some hop ups I think it can hang with any other race car out there.

[F150RTR]

Thats good to know that they have a good range.

thanks guys :).........its time to go out and play since the weather is nice.

[Jetskiboy77]

I wish I could go out and play, but its nasty by me.

[Asmenoth]

It's beutiful here, but I am still trying to figure out the gear mesh problem. Also, do any of you know where to get Wolfpack Radicals products from, besides Bruckner Hobbies?

:D

[Jetskiboy77]

I think you can send him an email and deal with him personally. I think.

[vegasdrift]

The R40 can only use rear exhaust engines. I think the RS4 3 is a great race car for fun and the weekend, and with some hop ups I think it can hang with any other race car out there.

Well, I would rather buy something that straight drives and handles like a dream right out of the box rather than buy hop ups for a sport level car. This way it's cheaper because I'll be starting with a vehical that I won't out grow. The only thing about buying a high performance car to start with is that I may not like the class. Then I'll have spent all that money for nothing.
What to do, what to do?
Anyone know about belt maintenance on belt driven cars?

[josh222]

all you have to do with the belt driven cars is change the belts, they don't wear down that fast, from what i know from my lhs(head guy lives down the street) the belts last pretty good.

From what you said the RS4 3 will be fine

[vegasdrift]

Does the r34 3 use rear exhaust or side exhaust engines?

[josh222]

it can use both, it has a side exhaust engine stock but a re can be used, like the engine i have is a rear exhaust engine

[gielamonster]

EDIT: Found what I needed, nevermind.

[gielamonster]

[QUOTE=azizhousecallz]we race @ night!
a few months ago it was just me... now its about 15 of us + my wife!
we turned a parking lot into a drag strip and track. with cars and trucks burning up the lot we all have become friends and we have a great time with our cars.


nice pics..whats done 2 ur car?? and where do you guys race @?

[azizhousecallz]

race clutch, race air filter, stiff shocks, and a ton of bodies. try to leave it as stock as pos. we race in the parking lot @ the sov.bank.arena. every night! its really sick!

OK i just got an rs4 3 ss ....besides graphite and universals i am wondering what else should i do to it? i want it for both track and street runs

[envelope]

where u from?

Austin, Texas

[trw]

whao there lol, im down here in Houston :D

shew, i just pulled out my RS4 3 and dusted her off, gonna fire her up this weekend, i forgot how fast she went. :D

they are quick! when im out with the fellahs its always a dash to catch me. and i dont care what anyone says. while the others are tring to get their cars running im running up and down the track. my hpi rs4 3 evo fires up every time with no problems. hats off to the HPI engine team! lol! :D

[josh222]

they are fast cars, TRW Rs4 3 might hit 60mph witht he cvr18, mine wil hit that mark with my XS but i will take longer, i think this summer i might go for a speed setup, .18TZ send it to get ported, high gearing, mugen 1/8th wheels, stuff like that :rolleyes:

[josh222]

i am gona get a Ford GT40 body and i am painting crome with dual white strips down the lenght of the car, shoud have that in the next few weeks

[trw]

i could prolly squeeze 65 out of it with the right gearing.

and i thought the TZ was already ported lol, if not....GOOD GOD that things gonna be a monster when ported.

[josh222]

i am not sure, i don't think OS ports them from the factory, if they don't i think it will make an easy 2.5hp :p

[StReeT Racer J]

wud a 15fe anodized heat sink head wrk on a T-15 engine. my RC runs like a race car but its jus the head tht stands out

[josh222]

i don't think so, i am pretty sure they have different bore sizes

[StReeT Racer J]

really danm. well wht knd of head can i put on it thn

[josh222]

whats wronge with the stock one? if you don't like the color you can paint it, duplacolor has Metal Cast fake Anodized paint the is gas/oil/heat up 500f proof

[Silent Night]

he said its too big and sticks out...if the fe head did fit you might get some cooling problems...

[josh222]

what kind of body are you using, if it sticks out use a different body

[trw]

never use CVDs, ever.

was on my 2nd run today with my new center CVDs, pop, rear one falls apart, more money wasted on damn CVDs, unless u wanna waste time putting shrink wrap around it, get universals.

i have to replace my differentials now anyways, would using the gears from the 18SS raise my top end speed or lower it?

[josh222]

they are the same amount of teeth just that there hardend gears

putting shrink wrap around them takes about 2 seconds.

can anyone tell me what car it is from the very blurred photo?

[josh222]

hard to tell but it does have a 2-speed gearing, battiers, body, futuaba radio, fail safe. i think that wasn't a bad deal, it said it comes with instructiions and those should tell you the make, but i can tell you it is a belt drive and it looks like a dual tip exhaust but hard to tell. when you get it take some godd pics and then it might be identable

[josh222]

the engine looks simular to this one.. the AE .12

[StReeT Racer J]

koo thnks well at least i hav sum mods to go by as a basis

Can anybody recommend a replacement chasis for my SS?

Thanks in advance

not as much cooling as compression it might lower or raise overall compression which that in turn means that it could be a dog..... or it might detonate :D

Thanks alot! :)

[KronicRacer]

^^the hpi super chassis is an updated chassis for the nitro 3 thats made of 7075 aircraft aluminum and ranges from 50-70 depending where you get it from. also its one of the chassis out there that enables you to set the droop on the car.

[Trollcifer]

I'm not sure setting the droop is worth an extra $50 seeing as I'm just a PL basher. But thanks for the information.

[Zoo Tv]

What is droop?

[trw]

droop is the clearance between the A-arms rest point and the chassis.

it affects the travel and ride height(slightly) of your suspension.

[josh222]

it is very handy for tuning :)

[KronicRacer]

droop is the clearance between the A-arms rest point and the chassis.

it affects the travel and ride height(slightly) of your suspension.


it lowers the overall cg and roll center in the rear which the nitro 3 needs.

it will also dictate ride height in the car (more than slightly) for the rear. how low it will go will depend on the length of the screw used in the lower arms. ive managed to get the rear down to 4~5mm. the front does not need it as much as the rear does. :)

yup i got it off ebay
it is louder than the stock pipe. never got a chance to run it on the stock motor to honestly tell if there is a difference with it. ive run it from day one on the fantom and ive had no problems with it.

well i went out driving yesterday and really opened up my new motor, dam is it fast, it is geared a bit to high so i am lacking in the low end and i think i am going back to stock gears, stripped first gear to while drag racing :)

No offence but you wasted your money on that pipe.

And what pipe would you being talking about?

in 7 laps my center universal broke and I wasn't even driving it that hard!! anything stronger than a center universal!

[josh222]

what broke on the universal? did the pin fall out of the joint?

this one, it's krniks or something liek that...

[josh222]

i have seen those pipes before, they look like something that could be done by anyone who can weld aluminum, but atleast you get some low end but you will have to richen it up a bit

[azizhousecallz]

I just got a new T-15 for my RS4-3 Evo during the break in i noticed that the flywheel was really tight. After i ran about 3 tanks of fuel the pull start would not move, and i could not spin the flywheel. after a little more force i was able to pull the cord. COULD I HAVE TIGHTENED THE FLYWHEEL DOWN TO TIGHT? or could there be something else? the break in is going fine and the motor seems to be fine i ran 4 tanks @ idle last night. And i will run 2 more tanks today then start some low speed runs. BUT before i go that far i just need to know if i should make any adjustments.

[azizhousecallz]

just a note: I emailed HPI about their engine exchg program for my T-15 it was not listed on this list:
1600 Nitro Star 15SS $99.00
1601 Nitro Star 15SS Precut for RC10GT $99.00
1605 Nitro Star 15 $75.00
1606 Nitro Star 15 Precut for RC10GT $75.00
1610 Nitro Star 15SC $99.00
1615 Nitro Star 15FE $55.00
1623 Nitro Star 12R SC $99.00
1626 Nitro Star 12R SS $99.00
1401 Nitro Star 21BB $99.00
1406 Nitro Star S-25 NEW! $99.00

when the email came back it said: "yes we do an exchange for the T-15 its $110.00 dollar" They are crazy! They have the T-15 listed on their site for that price new without the exchange program. Just so you know if you run into this problem with HPI you will hit a brick wall. SO i went to Tower Hobby and got a new T-15 for 69.00 dollars new. Thanks Tower! Shame on HPI for not having the T-15 listed on this list when so many people are buying this engine. MONEY & GREED! :mad:

[T-EVO RACER]

exactly the pin came out!!!!????

just take theflywheeloff anf put it bacl on agian

[josh222]

the reason the engine is somuch on hpi's site is because tower buys in huge bulk and hpi doesn't sell them in bulk from there site, it isn't about greed like the 15SS is 130USD on tower but hpi has it for 99

ok ok! but first let me say thanks for the flywheel info. and second HPI does not even list the T-15 on the list for the exchg program. thats just not right bro! they sell millions of those T-15's. ;)

heres the explanation on the pipe selection..........
less restriction is good for big tracks. (top speed).
multiple chambered pressure is good for the small technical tracks. (acceleration)

[T-EVO RACER]

I run a tc3 pipe

[josh222]

but it will open up a bit on the low, there mostly for show in my opinion, well i am think i am going for some gold pinions and a new spur and i should get a flat pack next week and maybe a clutch and brake or graphite shock towers

[PhEnOmEeNaL]

http://www.geocities.com/phenomeenal/rs4_3.jpg

My rs4 3 got:
.15 Sirio engine
2-Speed
Aluminum Upperdeck
Aluminum Pipe
Tell me what you think.
If you dont see the pic tell me.

[MT2 owns you]

yes, i can see it, its nice too. does that aluminum upper deck cause radio interference or is that woven graphite?

[PhEnOmEeNaL]

its a aluminum upper deck and it doesnt cause any radio problems

[MT2 owns you]

then i guess it was woven graphite i was thinking of..not sure though. still a very nice looking car. who makes it??

[Silent Night]

its an hpi....unless you are talking about the upper deck...

[trw]

the woven graphite doesnt cause interfearence at all, atleast ive never expirienced any with mine.

[Zoo Tv]

Where you get it?

[PhEnOmEeNaL]

i got my aluminum upperdeck at my nearest hobby store for like 30 bucks but i forgot what brand it is

[josh222]

you are thinking about manifold vibrating on metal tuned pipe, upper deck doesn't vibrate

[MT2 owns you]

yea that was it! but i could swear that either WG or Al near the electronics caused glitching. well, good to know i was wrong, in this particular case.

[josh222]

well i am getting fuel and some other stuff sunday :)

[rs4lola]

Just installed my new spectrum system for a Futaba 3Pk on my rs4-3. Works...fantastic. No problems during binding except I blew my digital throttle/brake servo!!! (Hitec...not so good maybe). I still have a digital high speed servo for steering, which is where I need it more anyway. The response is fantastic and no more interference. Next week going practice racing with other cars and hope to have R40 centax clutch properly tuned by then. Ran this weekend with 3-shoe NTC3 clutch which works real well but would like lower gearing for better acceleration. With an R40 centax clutch installed, I can go both lower and higher in my gearing. No doubt about it...get that spectrum!!!

[Zoo Tv]

Hey Kronic, do you need the graphite upper deck to run 30mm rear rims/tyres?

[KronicRacer]

i remember the stock radio tray interfering. with the graphite theres prenty of space to run 30mm tires.

btw
josh
should be testing the new "stuff" weve been talking about tonight...

[NitroTXT1]

can someone help me out...I wanna race my rs4 but i also wanna drive on the street so besides foams,graphite,universals,and threaded shocks what should i do? and also are there any little tricks that you guys know of that will help the car handle better...also what would be good gearing for my car? the track i race at is about a middle sized one i would say...i used to run my nitro 4tec back when i had one and i could hit top speed with normal gearing and appropiate shift point....just want to know if there is something i didn't cover

[Asmenoth]

You could use this as a guide, got off of the HPI site:

Revelation Raceway
Dedicated on-road track, smooth surface, high grip, large size

Front
Pink Pro Linear springs (#6759)
40wt Team Orion shock oil
#3 piston setting
Firm shock bladder (#72112)
Lower arm mount hole "A"
8 degree C-hubs
Woven graphite shock tower (#73047) hole #1 top, hole "L" bottom
4.5 mm ride height
2 degree camber
Team Orion foam tires 37 shore (26mm)

Front C-hubs were modified by cutting off camber link mounts and using #A317 Rod Ends at the
end of the turnbuckles instead of stock ball cups. Insert a #A132 Ball pivot in each rod end,
then use a #Z059 countersunk flat head 15mm titanium screw to attach the ball/rod end where the top kingpin
normally goes (the stock hex cap head screw). The effect of this modification was to make the turnbuckle "captured"
and allow better camber change as the suspension compresses.

Rear
Pink Pro Linear springs (#6759)
60wt Team Orion shock oil
#3 piston setting
Firm shock bladder (#72112)
Lower arm mount hole "A"
2 degree hubs, hole #1
Woven graphite shock tower (#73048) hole #2 top, hole "L" bottom
5.5 mm ride height
2.5 degree camber
Team Orion foam tires 37 shore (30mm)

Rear turnbuckle connection to uprights modified similar to front C-hubs,
except the uprights were not modified. This was to add a "captured" end to the turnbuckle.

Engine
Novarossi MR12 rear port SG shaft
Associated header
Novarossi 6802 pipe
McCoy MC 59 plug
HPI Power Fuel 30% fuel
Yokomo 3 shoe clutch (for SG shaft)
Yokomo flywheel/collet (for SG shaft)
Wolfpack Radicals adjustable engine mounts (WLF054)

Body/wing
HPI Stratus 200mm body (#7416)
Touring Car Wing set, 195mm wing (#7115)

Transmission
18/23 pinion gear (#76978/#76983)
39/43 spur gear (A445/#76843)
Wolfpack Radicals clutch type 2 speed (WLF061)

Gear box
Front one way (#86122)
Heavy Duty Gears for rear diff (#A856, #A857)
50,000 wt rear diff grease

Other
Wolfpack Radicals steering cranks (WLF065)
Fiber Brake Disk #A844 for more consistent braking, place fuel tubing between the brake plates
(on the screws) for consistent action

:D

[Zoo Tv]

How much grease to put in each diff?

[josh222]

Well i got my xs broken in and with 18/43 21/39 gearing my ss hung with a tc3 with a tr and a tamiya withy a RB SE engine :D well i went to stock spurs and gold pinions, so i think i will eaten those guys up next time :p and i just got a graphite front shocktower and by sunday there should be the rear shock tower, racing clutch, mp6 brake and a flat pack in it :) it is gona be sick :p

Hey Kronicracer how did the "stuff work out? i might get the parts this week end and i think lola you might like this to :)

[azizhousecallz]

yesterday i added adj. turnbuckles, frnt & rear universal joints, carb/fibr frnt & rear shock towers, and better springs. MAN!!!! :eek: i was shocked @ the difference! I did not believe it would be seen! after a tank i put on some new foam tires and man i lit the parking lot up last night. every night about 10 guys come out to bash the lot. I lay down some plumbing tubes to make this 10x65 ft circle we race around and let me tell you after watch the way my RS4-3EVO smoked the others im going to the shop today and get other upgrades. BIG difference! I just could'nt believe it. :D

Hey Kronicracer how did the "stuff work out? i might get the parts this week end and i think lola you might like this to :)

minor setback.... forgot to charge my sb batteries. LOL thats charged now i need to retune the fantom for the new flywheel i got. <-- (something serperate from what im testing) im hoping the weather holds out right now it looks like some rain clouds are coming in.

there are also some very minor things in that the old shock towers from hot bodies are no longer available. so hopfully hpi carbon shock towers are in stock again very soon(they are similar to the old hb towers in the wide body post setup).

also im thinking that eveything sould hook up with the basic stock towers.

theres many versions from basic to wild with what im testing right now ive got it with the wild config.

more to follow.

[josh222]

very good to hear :D

[Zoo Tv]

ok, this is what you need..
Two 2turnbuckles about 60mm
4 ball ends with m3 thread
4ball cups

Hey Josh, another question (great solution to the castor prob fella!), how to tighten up the loose steering - ie, too much slop / play in standard config???

Also, am worried about how often I need to pull apart my diffs? In the manual for the RS4 3 18SS kit it said to use the grease provided, should I replace and fill with oil?

Is there such a thing as diff oil?

Thanks,

Zoo

set back again :mad: :mad: ...... broke the throttle arm on the fantom last night :mad: took me a while to find a replacement (good ole 15fe throttle arm fits on the fantom fr12 03). by the time i did it was too late to go test. so instead of jynxing myself and saying today, hopefully by the end of the week i'll have something :D

[Zoo Tv]

Thanks Kronic. Any suggestions on the diff question?

[KronicRacer]

do not use oil. it will leak out and make a huge mess. if anything get valvoline axle grease(black) from the local car parts store. its better than getting associated's or hpi's stuff which will cost you a bundle for a small amount.

[KronicRacer]

and for my 2k post a teaser shot of what im working on

[josh222]

hehe, atleast i know what it is... what is the total cost for the parts? did you use the g4 or tc3 stuff?

[KronicRacer]

ntc3 v2 wasnt available

[M3EVOlution]

What's the best sounding/most effectiove tuned pipe for my HPI rs4 3 evo. Looking for a real nice sound. And also, are there any air intakes available for these cars?

[josh222]

get a Motor saver filter, there good. those cold air kits are a joke, thats what a hole in the body does, ths makes a really nice exhaust for the rs4 3

[rs4lola]

Hey Kronicracer how did the "stuff work out? i might get the parts this week end and i think lola you might like this to :)
Cool!!! Anyone still hopping up their rs4-3 has got it goin on....
I use 18/44 and 21/41 gears with an R40 clutch (all green gears) and the pickup is fantastic. Took me a little time to adjust the centax but once setup for acceleration, car just jumps on throttle now!!! With the 1/8 front foam tires all around as well as proceed springs, this car hugs the ground like crazy.
Very little oversteer but great turn in. Car is now built for short course track as it accelerates very strait like a bat out of hell!!! Going to track this weekend to see what we can do against other "pro" nitro racers!!! Next up is a solid axle for the front diff, sway bars from serpent and maybe some alum steering arms.

[MT2 owns you]

what about rd logics? they amke a pipe wiht a huge aluminum stinger..arent they a good company?. what about fuel filter..doenst do much for sound but still a good idea.

[M3EVOlution]

air kits are a joke, thats what a hole in the body does, ths makes a really nice exhaust for the rs4 3
How is the ths sound compared to stock? How about the ACE pipes on ebay? How do they compare to one another?

[MT2 owns you]

i got one too. its loud for one, and..im not sure how to describe it, but it sounds nice. basicly loud and highpitched. one day my dad started his charger, and that is pretty loud..then i started mine..i had to move away..it hurt my ears..its louder than my dads charger..

[Zoo Tv]

hints?

Do you have the ths or ACE?

[josh222]

hw got the ACE

[josh222]

hey Lola does that kit from wolfpack include wheels or just the wheel adapters?

[KronicRacer]

Do you have the ths or ACE?

the ace reminds me of a chainsaw :D

[rs4lola]

hey Lola does that kit from wolfpack include wheels or just the wheel adapters?If you are talking about the 1/8 adaptors, they just include the wheel adaptors to mount 1/8 wheels onto a 1/10 scale. No wheels included...

[josh222]

alright, where did you get your wheels? Hobby Hobby?

[Silent Night]

are there any chassis that will let me use 19/42, and 22/37 gears? the gpm chassis i have now won't let the engine get close enough to the spur...i can't cut it because there are also mounting holes for the fe..

[MT2 owns you]

i learned this trick from coolhead if you wanna try it. itd be cheaper..all you need i a drill, hammer, and one of those centerpuch dealys..get some puddy, pput it on the chasis, put the engine down when you need it and then remove it leaving the puddy. since it is soft it will leave a mark when your holes need to be..center pucnh where the hole imprints are and then drill it out..should work..i think thats how it works.

[Silent Night]

i know where the holes have to be but the fe mounting holes will mess everything up by making one large irregular hole...

[Silent Night]

this is what i mean



well not that far but maybe like 5 or 6 mm in that direction...

[Silent Night]

this is what i might look like... a bit.. give or take a few mm...

[Silent Night]

and this is the original
http://www.hpiracing.com/graphics/parts/73902.jpg

[Silent Night]

so i would need somthing at least like this...

[josh222]

just cut longer slits

[MT2 owns you]

why would that be a problem? the point of the holes is to hold the engine on, not be an even hole. unless the oversized hole would make the screw go through the hole instead of helping hold down the engine...thatd be a problem...think of it this was- itd lighten your chassis :)

[Asmenoth]

are there any chassis that will let me use 19/42, and 22/37 gears? the gpm chassis i have now won't let the engine get close enough to the spur...i can't cut it because there are also mounting holes for the fe..

Are you still using the HPI motor mounts? If so, you should probably switch to the Wolfpack Radicals adjustable motor mounts. I changed to 18/23 and 39/43
gears and they would not mesh at all. I almost tried cutting the chassis as well. After checking around, I found www.wolfpackradicals.com and e-mailed the guy and ordered the adjustable motor mount and, like magic, after installing it...the gears meshed. The mounts allow the motor to move inward more and slide forward and back as well.
