HPI RS4 Sport 2 Forum

[DanzST]

Anyone have an RS4 Sport 2? I got one and wonder how people have modified them to perform? Before I get bashed on, I am on a budget and got this one new in the box for $100, I know it is a little old. I am new to on-road and wanted to start out simple. It has a Novak reversible ESC and Peak Aurora racing motor. I had these components laying around and put them in it cause it was all I had. The thing flies around my neighborhood. Any help is appreciated.

[StevePond]

That is still a very popular car. I think I like the new RTR 3 better because of the shaft drive, but I certainly wouldn't pass up a "2" for $100 new. :D

[DanzST]

You think $100 was too much?

[StevePond]

Sorry, that was a typo that I fixed. It should have read "wouldn't."

[DanzST]

I got it.

[DanzST]

SteveP-
Bob Hastings told about a company called Hobby Tech as a place to go for wheels. I'm having trouble contacting them. Do you know if they are still in business? Do you how to get a hold of them?

[DanzST]

I tried those numbers they list on the website and I get a message saying they are out of order. Do you know of any other numbers to get a hold of them? Thanks for helping me on this.

Dan

[StevePond]

I'm sorry, but that' the best info I have. Is there a certain type of wheel you want? maybe you can find it elsewhere if you're not able to get in touch with them.

[Gmanlusk2004]

no one else has a sport 2? I just found this thread... and i want to keep it alive! This is a very competitive car! I know, it's not graphite, or carbon fiber... but its the next best thing, fiberglass!! I have won many races with my sport 2. I would want a pro 2 over a pro 3, but i didn't have enough money for one at the time. Anyway, i still win races over x rays, tc3s, pro 2's and 3's. It helps to have a good, expensive car, but it is all about the driving baby!

I have a sport 1, does that count?? im needing 3 dogbones,wheels,and tires to finish it up. body is a blue dodge stratus. :)

[DanzST]

Garrett-

Thanks for writing in. Since I started this thread A LONG TIME AGO, I've made many adjustments to the Sport. I don't have a ton of cash so mostly chassis tweaking. I run an Aurora Racing motor by Peak. Have no clue about the motor, got it in a trade. I just know that with the stock gearing it hauls butt. I had a kid at the track go "is that really an electric?" Nothing fancy on it either. I did put HPI X-pattern radial tires on it. For my track/ driving style, I have put 3 degrees camber into all four wheels (I think that is how much). I used the extra parts that came with the kit, then I cranked down the links to get the top of the tires in. When it is sitting still, all four outter sidewalls of the tires are off the ground resting on the inner sidewalls. When she is moving though they flatten out and when I go into a corner they make total contact giving them the most traction. It is an odd setup to some, but for me it works just fine. Still perfecting the setup though. There is a pic in the "paint, detailing" section under "first mask job" (wouldn't let me post it twice). Tell me what you think and we can keep this going. Glad to know someone else has a Sport 2.

Dan

[DanzST]

I forgot to include you in the last reply. As far as I know the cars are the same. Difference is the Sport 2 uses the same steering/ frontend setup as the Pro2. Other than that I don't think they are that much different. Glad to here there are still some out there running. These are good solid cars. They don't cost an arm and a leg either. Really lets you do what your supposed to and that's DRIVE. Thanks for writing in.

Dan

[spenzalii]

I've got you all beat. I found a HPI Pro not pro 2/3 or sport. I bought ot off eBay for cheap. I have the Pro2 A Arms so I can convert the front suspension, but all else is pretty much stock. I'll add the RR diffs, aluminum knuckles front and rear, pruple side brace and call it a day. I thought about converting it to Pro2 spec, but it would be pointless (I would need upper and lower chasis, the Pro is 2mm shorter, and it makes a difference).

[Albertt]

even though I have a TA04 myself, a friend has a Sport2. Since he's new and I've been into RC for 10 years now (off and on), he usually asks me for advice on setting things up on his car.

[Gmanlusk2004]

well i run my sport a lot, but not as much anymore. I got a Storm, and this thing is awesome! Anyway, my Sport 2 is helluva lot faster than my Storm if that tells you anything. I have a custom 10X2, hand wound motor that my LHS special orders from some place in Arlington, Texas. The company is called Light Speed. It hauls serious ass. I figure that it goes around 65mph easy, and yes i race it like this! I have to run treaded tires at my house though, i don't treat my driveway and it's smooth concrete w/ a lot of dust. The treads make an awesome screaching noise when i peel out or skid to a stop or power slide around a corner.
The rims with the treads are chrome gumby, and my slicks are the stock rims w/ new tires.

P.S. the pic is too big to put on this page click on the link to see it. My HPI RS4 Sport 2 (http://rcuniverse.com/attachment.php?s=&postid=293084)

[rcmania67]

I just got the Sport 2 yesterday with Hitec Lynx AM Radio & Novak Explorer II ESC used. It is nice. Very quiet car. I raised it up a little and used TC3 Spring for the front. It is more stiff.

I'm planning to get X-Pattern tires, a mod motor. The ESC that I have can handle 15 turns. Which motor should I get? What gearing should I put on it to go fast? Right now, gearing is 87/26 wiht P2K

[Gmanlusk2004]

use the same gearing, just get a Trinity Speed Gems pro motor. Those are great motors at an awesome price.
Later,
Garrett

[Dirty-Redd]

Sport 2 is a great car, I hope this thread can wake up 'cause I know about 3 other giuys that run them, and everyone needs support at times. I have a good setup and I beat TC3's and XXX's daily. For the price I don't see what's better.

[timberwolf211]

I just got my hands on a PRO sport 2. Can I join this thread too? I am still trying to work out the slop in the steering and the gearing. I was wonder you guys reccomend. I have a speed gem 13 turn motor and 27/90 gearing at the moment. But after looking at the manual it looks like I am little under geared for this car. I am thinking about going to 38t pinion and 106t spur what do you guys think?

[Dirty-Redd]

If you us that gearing you'll tear up your car. The largest gear and spur you can use on the Sport2 is a 34T pinion and a 93T spur. I personally use a 28Tp/87Ts, and it's very fast with an 11T motor. Remember, each car is geared differently, and your motor plays a major part as well.

As far as setting your car up is concerned, sometimes it will be more difficult then other cars. But once it's locked-in, it's locked-in!!

remember - Pinions : higher is top end , lower is torque
Spurs : Higher is torque, lower is top end

You want to get the best "Happy-medium" for the cars best performance.

If you want to drag with a 34Tp/78Ts go right ahead, but be careful because even though it's fast it'll probably burn up your motor after a couple of runs.

[timberwolf211]

Thanks for the help. After I downloaded the manual I realized that I was looking at the gear selection for 64 pitch and not 48. So I went home and looked at my gearing again. Come to find out I am running 27/90 and I switched to 27/87 and what a improvement. The car flies now. Also I am in need of a new motor as my speed gem is really old and could use a lot of TLC but it works for now. I don't plan on doing any racing anytime soon so I can take my time and re-do anything that needs it.

[rx78gp03s]

i own the origional hpi rs4 pro. and i' wondering if i can post here seeing that there is no rs4 pro forum and that both car share some of the same parts, so can i?

[spenzalii]

Join the club. I too have a Pro. Some of the parts are compatable, but others are not. For instance, the lower A arms are different front and back, and the hub carriers are totally different in the front. If you REALLy want to, there is a list of what's needed that will convert to Pro2/Sport2 spec, but it really isn't worth the trouble.

[Prinler]

Hey i just purchased a converted sport2 to a pro 2. $100 shipped. Where do i find hop ups? tower doesnt sell any that i can see. :)



Whip the mice to make it go faster.

[rx78gp03s]

i dont plan on converting my car ne time soon to become a sport 2 or a pro2. i think its just fine. tho i'm making a new lower deck for it, but yeah. woot i'm in da club. Try Hamud Ghuman's website. they got tons of aluminum parts for the rs4's

[Dirty-Redd]

if you need parts start at HPI's website. or try this link
http://www.hpiracing.com/buyhpi.htm

[Dirty-Redd]

oh yeah, when you pull up the link go to KIT Parts and select you car

[timberwolf211]

I ran Pro for the second time this weekend and I am really impressed with the way it handles. I even got ran over by a few T-Maxxs and did not break any parts. I am going to take some time over the next few months and get a better steering servo and make sure everything is dialed. Then I might start racing carpet if find out a track schedule.

[Prinler]

Alright. On a 13 turn motor. On 48 pitch.. what would be a good pinion to use? Im not sure what to put on it.

[timberwolf211]

I have a 13 turn motor in my Pro 2 and I am running 27/87 48p gears. Also on HPI's site I downloaded the gearing chart from the PRO 3 which had 48p and 64p gears. Also the PRO 3's final drive ratio is almost what the PRO 2's is. So I use that as good refrence guide. Also I have found that the motor does not get real hot.

[Dirty-Redd]

on a 13T I would drop my pinion to a 24 or 23 to increase your torque. Try it, the difference will be noticeable.

[Gmanlusk2004]

well, i have a 10X2 and i'm running a 26/109 and my motor gets extremely hot. I don't know why, i have it undergeared by far. It gets so hot that my brushes become unsoldered! It goes about 40 w/ this gearing, but i know it can go much faster. What should i do?
L8r,
Garrett

PS. I have Team Orion 2400 cells, and a novak dually esc

[timberwolf211]

Sounds like you have it overgeared since the motor is getting real hot. I would try going to a smaller spur and see what happens.

How effective is it?

[spenzalii]

Depends on what you want to do with the car. They made similar inner bodies for the rally and the MT. For show car or concours, or if you just want a cool look as your running up and down the parking lot, go for it. Not so great a choice for racing. You have added weight (every bit hurts...) and the motor is more enclosed (?), making it harder for it to getthe cooling air it needs, especially if your running a low turn mod

[Albertt]

Yeah, I thought about all that. It's just that my freind runs his Sport2 like a rally car and I was curious to how effective this inner body was for prevention of debris entering into the chassis. As it is now, his belts are torn up pretty bad and are going to have to be replaced.

BTW, he's running a P2k stock motor, but might switch to a 19 turn modified someday.

Thanks
AL

[spenzalii]

It's better than running without the inner shell, but debris stil gets in. After all, it's 2 pieces of lexan that aren't sealed by anymore than tape, if you eve use that. It will keep major stuff out of the chasis, but if you run rally, theye is still cleanup to do afterward.

[Prinler]

19 turn ? the stock will be faster. Not worth it. Anything from like 16+ will be slower if you have a good stock motor :)

[Dirty-Redd]

A 19T Pro Stock motor, is faster then a stock. That's why they seperate the class. And from Pro Stock you go to Mod.

[Prinler]

yeah but like a speed gem 19 turn MOD motor wont go as fast as a 19t Trinity Chameleon Pro. ECT.... Stock mod motor

[Albertt]

19 turn ? the stock will be faster. Not worth it. Anything from like 16+ will be slower if you have a good stock motor

Prinler: I found my TA04 to be a heckuva a lot quicker on the top end with my Team Orion 19turn triple than with my P2K.

I informed my freind of such; he purchased the inner body. I'll keep you fellas informed about how well it keeps the larger debris out.

Thanks

[hpijoepro2]

i know a way to stop all the play in the steering. on the steering arms were that metal bar is u have to drill a screw sized hole behind that bar. keeping the metal bar there u put a turn buckle there and make it push out farther than the bar. this make the bar pull the arms in, while the turnbuckle pushes out. i done this to my sport 2 and it handles way better :) :) :)

[ElBaboon]

heres a way to get rid of a lot of slop:
get part 12 from the A471 tree ( i think)
the part should look like it will be a (very) snug fit between the upper deck and the right steering arm. Trim the piece so that it still fits snugly, but not tightly(you may also have to cut a part of the piece so that the servo arm doesn't hit it). Make sure that the wide part of the piece rests on the steering arm evenly. Then just screw it place with a spare screw (dont worry if the hole on the piece is small, just screw tightly so that you can twist it). The steering should still be free, but you'll notice that there is much less slop in the right wheel.:)

[ElBaboon]

i meant "can't be twisted "

[rx78gp03s]

does anybody kno the parts # for the saddle pack holder for the rs4 pro? it should be the same thing like u guys.

[CivicRacer2003]

Oops. Double post.

[CivicRacer2003]

Here is a picture of my Sport 2, its decently fast, right not its RWD only since I just snapped the front belt :D Its quick though.

[Doh Boy]

why are you usin a reciever pack?

[Namack]

I just bought a sport 2 with a Trinity Speed Gem 2 Onyx 14T Double Motor and was wondering if anyone could help me so that i could make it run its fastest

thanx

[originalED]

Hey guys, new to the forum. I just bought a Pro 2, but I can't "personally" get to like the car. I got the car already assembled, but I want a kit. the car has a few option parts : a Robinson purple anodized rear diff., graphite shock towers, carbon fibre belt tensioner, 2 sway bars, non stock springs(white and yellow/green). The car has a few scratches underneath the chassis, but that does nothing to the performance. The guy I bought it from babies all his chassis. I'm asking $310CDN or somthing like . I also have a Trinity P2K2 motor I'd be willing to throw in. If anyone is interested email me or post. thx
Ed:)

[originalED]

i'm taking reasonable offers?? anyone??

[streetweapon1]

u might want to take that to the buy-sell-trade forum, u will get more responce.;) and that price is a little steap, how bout 159, thats the price at my lhs, well, just aski9n



who here likes OFNA?
my friend has 2 ofna cars, and doesnt like them, because the break alot, do u think ofna stands for, OH FU*K, NOT AGAIN?

[biturbo15]

I have my sport 2 and I love it. This car really kicks a**. has any one put on the handling kit from hpi? it looks like it just stiffens up the body. Also I would like to upgrade my differentials. SHould I go to one ways or graphite diffs? btw right now my car has a 14t double, intellispeede 8t pro reverse, futaba radio, and 2 2400mah batteries. Also what option parts do u guys think are a good buy? I want more speed!!!!

[SegaBowMan]

has anyone ever snapped a belt? (especially with a low turn motor) Where can I get this car online for 150 or less?

[biturbo15]

I snapped my rear belt on my sport 2 it hella sucked!! The part is only 5 bucks or so but it was a bitch to get back on. I had to practially take apart the whole rear half of the car. but my second one hasnt broken and I dont think it is going to.

[biturbo15]

what option parts have u guys noticed the biggest difference in when u added them? I only have a little money and dont want to buy something that doesnt help me very much.

[StangRacer67]

what turn is the motor?if its a 20 or above put a cube of ice in a plastic bag and hold it on the motor till it turns to water.

and if you have slicks rub sunscreen into them,let it sit for about 5 mintues then wipe all of the sunscreen off till the tires are dry

at www.towerhobbies.com you can do a searsh under pinion and youll have to scroll through a few pages till you find a 21-30 tooth pinnion set of 9 for 9.99 but make sure its the same pitch as your spur so theyll mesh good

[biturbo15]

I have heard about that ice trick.. Is it actually true? I am definently ready to try it!!!!!!!! I also heard that you have to use dry ice.... normal works?? I hope so!

[R33Skyline]

My folks just ordered me on the Syliva version of the RS4 Sport2 for xmas. I was a pretty surprised to tell the truth. I have run Tamiya cars for a long time now mostly the TL01 frame. I am curious to see what the handling characteristics are of the sport2 vs. the TL01. Nice to see there a forum here where I can learn something about this car. I haven't built it yet since I dont get it till xmas day. I was wondering a couple things though...I will be transplanting my Trinity Gem2 Sapphire as well as my Novak Reversible Rooster from my old TL01 into the new Sport2, do you guys think that would be a good setup for the sport2? Or should I leave that drivetrain in the old TL01 and opt for different parts? Also I will be building the car soon and was wondering if there is anything I should watch out for during the assembly process? Any tips or tough areas I should be aware of? Thanks in advance for all your help.

[biturbo15]

I had a little trouble when I was putting together my steering assembly together so be careful about that. This may sound stupid but I put my wheels on backwards. LOL that sucked. I thought they were on right so I just cut my wheel wells bigger and bigger until my tires didnt rub. my wheel wells are now 4 inches long or something............. ( give me a break it is my first car) getting the steering set up correctly was also a pain. Make sure to get the survo and turnbuckles tuned correctly. It tells you how in the instructions but it is kinda confusing. and good luck. It took me about six days. four hours a day. DONT WORK WITH THE TV ON!!!!!!!! it will ruin you. i put every part on backward that is physically possible to do so lol. Good luck.

[StangRacer67]

yes normal ice works fine dry does work better cause its colder but ive used normal for about a motnh now

and to the person who said they had 4 in wheel wells i cut my bottom valance too short and the wasnt enuogh room to put my head lights grill on so i dont have a grill on my first car body....heheh

[biturbo15]

I just took out my motor and froze it then I put ice on after. what a difference much faster!

[Doh Boy]

this threads actually alive now!!!!

noted: No TV when building. Thanks!:D

[StangRacer67]

yea i was suprized how much ice really works have you tried the sunscreen thing yet if you do make sure you wipe the tires completly dry or else you actually lose traction

and as far as the motor in the frezer yes good thinking but 1 dont leave it in there too long or else it will turn into a brick of ice 2 make sure you put it in a bag or wrap it in aluminum foil

[biturbo15]

I am getting a 9t trinity speed gem soon I cant wait. Ordered it from tower yesterday :D :cool: What pinion and spurr do u guys run with a 9t double though? Right now I am runnin 93/22 with my 14t and It runs pritttty good. acceleration is still really fast! top speed in like half of a second or maybe a second. but what gears should I use for my 9t??

[biturbo15]

people keep this thread alive, if u have nything to say say it!!!!!!!!

[R33Skyline]

got my silvia rs4 sport2 in the mails the other day, my parents wont let me look at it until xmas morning.

[StangRacer67]

i know what you mean happens to me all the time and by the way if you asked for a r/c car and you find a big box under the tree DONT shake the box...or if you do make sure youve got a good warrenty:D

[SegaBowMan]

When did the sport 2 come out? where can I get a new one for $140 USD

[spenzalii]

The RS4 Sport 2 is a few years old, easy. Even Tower has the kits for $154. It's an admittedly nice kit, nicer than, say, a TL01, and it can be hopped up to your hearts content. Companies made RS4 hop-ups like they make them for the T-Maxx. That said, it's a few steps behind the technology curve in a few areas, such as the suspension (still using the same basic setup as from the original RS4). But, it is a good car that can be competitive in the right hands.

[biturbo15]

Ya tower is probably the cheapest you can go. But u can get a used one with everything u need to run for probably 100 - 150 range.

[SegaBowMan]

yea. I would buy a used one but I don't like prebuilt or scratched up chassis. plus I could get a bum deal.

[biturbo15]

I was just thinking if u are low on cash. I am always low on cash:D Ya and my chassi is pirty scratched up. Currently mine is out of commision. Blew my drive transistor on my esc. :( Cant wait to get it back from the service department though

[xevious454]

I built A RS4 Sport out of the box. I put a 2 speed trans., not real sure if it is changing gears! Using a 3000 nh-mh batt. & 17w stock with A Tekin Command 10. It seem's slower now, Origanlly stock with warlock mod motor.. Looking for the highest top speed just for play. Any suggestions?

[EMT^Racer]

hi guys,
have any of u seen or driven a sprint as well? australia doesnt get the sport 2 anymore, but instead we get the sprint for about $230AUS (w/o body). im thinking of getting a sprint, but im just worried about the quality of the plastics and also, even though it has the same basic design as the sport2, the parts look a bit dodgy e.g the hub carriers and diffs. also, it doesnt come with turnbuckles :(

if anyones made a comparison, pls gimme some insight.

2 speed trannies dont help much. They are mostly extra weight. Especially if they dont even work. :D For high top speed I suggest a 12 or 13t motor. with the correct gearing. That is going to make the most difference. Then you get carbon fiber parts to lighten up your car, and then you work on handling. I have a 9t double and a 14t double. I break out the 9t when I am in the need for speed but I will race with the 14t the 9t sucks up my batteries too fast and it needs a lot of maintanence.

[Rinkrat99]

Hi all

I hope I have the right forum for the RALLY version of HPI's RS4

I currently have an Associated T3 and looking to move into the Rally field which will enable me to easily switch between On-Road and mild Off-Road settings. I am not planning on racing at this time.

I would like to know your thoughts on this car. Is it worth approx $160 (Tower Hobbies kit LXBSX4) out of the box or are there some must hop-ups which are needed such as Ball Diff, Slipper Clutch (is it needed on 4wd)?

Thanks for your thoughts.

[xevious454]

Thanks for the info biturbo15. I gonna take the 2 speed back ot and get another motor and gears then see what happens! Only way to learn though is trial and error.

Thanks for your thoughts.

No, this really isn't the correct place (look under electric off-road for a RS4 Rally thread).

Out of the box it will work for you but the slipper clutch is highly recommended. There are a few other parts that are recommended for this kit as well (heatsink motor plate for one, I can't think of any others off the top of my head at the moment). The ball-diffs are recommended for on-road use only and will require a lot of maintenance if you take them off-road.

[biturbo15]

I am thinking about getting ball diffs for my sport 2. my front diff sucks. I think it is broken. It works correctly but one wheel spins faster than the other when it is off of the ground. Do you guys have trouble with your steering collums? the plastic pieces on mine are stripped. so i glued them together and it works now. Have u guys got any experience with ball diffs? or bad steering collums?

[LanceS]

RinkRat,

The Rally does okay on-road, but it wouldn't be very competitve. That's essentially why I'm rebuilding my RS4 Rally into a 180mm RS4 sport. The rally didn't like the off road course at my LHS, so it's conversion time. But bashing in the driveway or parking lot with it is awesome. The kiddos love to see it hauling down a gravel driveway in full drift.

If anyone has some spare RS4 parts, please check out my post in the Wanted section, as I need some stuff to finish the car off.

Lance

[biturbo15]

this is not rally forum dude. the rally forum is in electric off road section. GO THERE>

[R33Skyline]

Got it for xmas and let me say, I am very impressed with the way things are laid out. The instructions are very straight forward and the parts are laid out in a somewhat good order. I started the project a few days ago but I didn't get very far yet. I plan on building more over the course of this week. Still trying to decide what color to paint the car too.

[biturbo15]

Ya it took me a while to build it. But it is worth it!

[tl01boi]

hmm should i get one of these are they competitive against the tc3 xxx-s pro 3 for stock racing its 120 dollars with a esc and 11 turn team orion motor

[Prinler]

Look what i did :(

[tl01boi]

ouch that is bad how fast were u going

i got my rs4 pro 2 with a stock tacing motor i noticed something i put the team orion 15turn pilot motor in and it was fast and then i put this stock racing motor and the stock racing motor was way faster than the 15 turn lol im not sure what kind of motor it is because it doesnt have any signs or logos on it but it is gold on the outside and green on the inside i think it's a hand wounded motor and man i love it lol. there is somehting else i noticed that the rs4 sport and the rs4 sport 2 are almost the same all u have to do is change the bottom chassis of the rs4 sport and put the sport2 chassis on it i don't really see much of a difference lol . p.s how fast does all ur cars go and what motor are u using

[Prinler]

I was going full speed. Full lock turn... looked like i was free and clear. Clipped the inside back wheele of a parked car. I am running a 12x2 d3.5 25/81 The thing smokes! im guessing low 40's.... My brushless should be here soon. Ill tell ya then :p

[tl01boi]

i mean racing motor

[tl01boi]

what kind of motor is that and where did u get it lol

[Prinler]

The one in the pic? Thats a Trinity D3.5 Hand Wound 12 turn mod motor. its an older version of the D4 or new D5...

This pic is the new motor i am putting in my pro 2....
Should make it go about 80+ from what i hear.

[biturbo15]

wow becareful when you accelerate with that dude. The belt system on the sport 2 is very good but it is still a belt system. Brushless motors are design'd for a real tranny with no belts. But as long as you are not putting a lot of stress on it by accelerating fast or going from full speed to reverse and so on you may be fine. I definently want to hear how fast you end up going though! What mods have you done to your sport 2? This question is for everyone. LIST YOUR MODS! I want to do stuff but I odnt konw what is good.

[Prinler]

I converted mine to a PRO 2.

new springs. Other then that/.... nothing. :)

[tl01boi]

hey how much does that motor cost and where can i get it

[Prinler]

You want to go brushless?

haha ok well here

http://www.rumrunnerhobbies.com/default2.htm
http://www.finedesignrc.com/cars-trucks.asp
http://www.hackerbrushless.com/cars/emax.shtml

[biturbo15]

so a brushless setup runs for about 300? wow. But if you go 80 I think it is worth it :D I just hope that whoever has a brushless can handle their car. 80 MPH + bad driver = colision with hard object = totaled car.;) I just hope I can get my car to 50 with a 9t or so. I have heard of people going forty with stock is this true?

[Prinler]

no way.
50? maybe 35

you pick up the controler and motor for $200
They LAST FOR EVER!
no Maitinece. No brushes. No Cleaning, Just replace the barring every 10 years.
They are like putting 5 motors in at one time.

They have 5x the torque ( higher gearing ) then 5x the top end. ( gear even higher)


BWAHAHAHAHAHA

[tl01boi]

i just lost my intrest on getting one haha 200 dollars man i could get another car for that much haha

[Prinler]

No... its not about quantity... its about Quality. *sigh*


For $700 I purchased 2 brushless systems. One for my maxx. and one for my t3/pro 2

check out my pix

[Prinler]

This is the controler... for the smaller purple one....
Well worth it... you never have to play with the motor. Nothing! Just give it power. Its Awsome... but then again its only for people who are hardcore for speed and power :) ARRR ARRR ARRR ARRR :) as tim alan would say :)

[biturbo15]

Back to the sport 2. Can you guys flip this car? I cant flip mine unless I hit something like a big rock or something I go full speed and turn and it doesnt flip. It makes me feel like I am understeering. Is that possible? do I need a different servo? any info is appreciated.

[tl01boi]

i cant flip this car at all and i dont want to lol when i go ful speed and just turn it drifts lol if your having understeer do what i did use slick tires in the front and radials oh yeah use hard foam for both lol

[biturbo15]

I found out that really I am oversteering. My car doesnt drift it just sticks. So I figure I am not turning enough. It is kinda frustratin, knowing that my turning radius could be better but not knowing how to fix it.

[Prinler]

When you turn at high speed, and it doesnt turn very good... Is called push. Its normal. When your going that fast there is to much force forward. If you tap the break right before the turn you should see an improvment. Just keep on the gas while in the turn to keep from spinning out.

As for flipping. oh man... yes. Called Traction rolls. When you haul ass down a Straight then SLAM on the turn. Its Slides into the corrner. If you hit a crack or something making the car to stop sliding you will roll. My Max # of rolls is about 11. wasnt purdy. :(
5 cart wheeles

[biturbo15]

I get it make an S turn kinda, like if I am turning left I tap right and then turn left. Like in real car racing! WOW wish I realized that before. THANX. Cant wait to try it.

[Prinler]

Yes it pushes the the CG over to the front again. Try taping the break before you turn, or even coasting

[tl01boi]

haha yes drifting rc cars are fun umm what kind of tires do u use for the frotn and the rear i use medium slicks in the front and medium radials in the back it handles better that way

[Prinler]

I personally run Tred tires in front and slicks in the back. The front seems to love treded tires. i hate them cause they wear down so fast :(

[biturbo15]

I run HPI advan tires all around. they are a low wear treaded tire. Great tires I must say. Great traction and i have been running them for like a month now with almost no ware.

[tl01boi]

tomorrow im going to take the front bumber off my rs4 sport 2 and but supernitro tires and rims on ym car instead to test speed and acceleration then after that im going to put nitro mt tires on my rs4 sport 2. do you think they would let me run supernitro tires for racing at my track there just bigger lol

[tl01boi]

hey i was wondering has anyone ever beatin tc3's xxx-s pro three yokomo cars in stock class racing and if so what motor did you use and what set up

[biturbo15]

I havent raced before but I have heard of people doing goood with a no limit esc and a trinity p2k2 stock motor.

[Prinler]

I would recomend a P2K "2"
I had a motor with Amazing #'s But sucked when it came down to runing it. P2K's are awsome tho :)

[biturbo15]

my nitro friend came over and he is off road. I set my shocks so that my ride hight was at its highest and this things handles pritty good off road! nothing hardcore but a little dirt is just great! I also put on different tires but ya It works pritty good for a touring car. I solved my turning problem. I set up my shocks differently and now I slide a little when I turn, not much and only if I turn hard. This car is great. I had my esc that went to 8t but it broke. I am now running my old esc with a stock motor and this car is still fun. I just love it.

[biturbo15]

I am in the process of cutting away every piece of plastic on my sport 2 that doesnt belong to make it lighter. It is really fun. Have you guys tried it? So far I have done both shock towers and the battery holders. Did I miss any pieces? I will post a pic of my car some time tomarrow. and oh ya.

MY ESC GETS HERE TOMARROW!! I HAVE BEEN WAITING FOR LIKE 3 WEEKS NOW!!!

[biturbo15]

my car.

[tl01boi]

i have a sport 2 and a sport and im goin to convert my sport one into a sport 2 i need the chassis and the rear arms is it worth it 60 dollars for conversion. should i do it whats your opinions theyre almost the same car

[tl01boi]

one more what motors are you guuys running and what pinion gear and spur gear im running a 116 tooth spur gear and 17 tooth pinion gear in my hpi sport and im running a 86 tooth spur gear and 16 tooth pinion my sport 2 has a psk pro stock motor i just got and my hpi sport im not sure what kind of motor it is but it says epic 27 do u guuys no what kind of motor it is and how many turns it just says epic 27 lol

[tl01boi]

have u guuys beat tc3's xxx-s pro 3 with ur sport 2

[biturbo15]

wow ok. The new chassi for the sport 2 should be better. Instead of getting plastic sport 2 a arms you could get the carbon graphite upgrade and those will be lighter and better. WIth my 14t double kyosho I run 25/93 with my 9t double trinity speed gem pro I run 22/93 maybe 23/93 if I really push it. I havent raced yet but I plan to kick some xxx-s and t3 butt.

[PCC]

I've gone over this before. They're not "almost the same car". There are a lot of differences between the two and converting the Sport to a Sport2 (for that matter, why not the Pro2?) will cost more than you think to do it right.

[biturbo15]

I need more speed. any advice?

[Philly's Finest]

Hey everyone!

I have a sport 2 but I don't think I've ran it in over a year. I got the nitro bug and haven't looked back til now. I used to hang over at the HPI electric fourms last year but they have since gone down.

Anyway I'm thinking about getting back to my sport 2. I really loved that car. It's great out of the box. Might even take it to the track this year & run with the tc3's. I was thinking about maybe getting a new car but I'd rather stick with what I have.

Anyone still make hop-ups for the sport/pro 2? I might just get a pro2 off ebay and use it for parts.

[biturbo15]

HPI still makes parts for the pro 2 and sport 2. SO I think you can still buy them from either tower or hpi online. What top speeds are you guys getting out of your cars?

[minijosh]

I heard that the sprint is taking the place of the rs4 sport 2 and the racer version. Is this true?

[Philly's Finest]

Well the pro2 has been discontinued for quite some time now. The sprint has been around for probably the same length of time. It probably will cancel out the Sport2 but no word from hpi yet.

[biturbo15]

The sprint is an RTR version of the sport 2 in my opinion. But I like the sport 2 better (probably cause I have one)

[minijosh]

I bought a kit over here in england and I had to put in my own motor, esc, receiver, servo and now it runs. They don't sell it rtr over here.

[biturbo15]

weird. I dont want to sprint to replace the sport 2. We need more hop ups for our car as is.

[Prinler]

Convert to a pro 2... they have alotof hop ups... those are kind of the hope ups... like on a AE... they gave Factory... and TEAM and stuff...

[Prinler]

Or do what i did... purchase a $250 brushless system :) make it do 90 :)i love my pro 2. Only problem is it uses belts and well they slip alittle still fun :)

[biturbo15]

is the pro 2 better or worse than the sport 2?/

[Prinler]

pro is much better//
Fiberglass chassis you got now.... goes to as carbon graphite :) lots of purple alum ect.

[PCC]

Originally posted by biturbo15

Think of it this way, take your Sport2, and hop it up. I don't mean change the plastic parts for aluminum, I mean change the FRP chassis plates for sheet carbon fiber, the heavy gear diffs for lighter and externally adjustable balldiffs, the inefficient dogbones for lightweight CVD's and you have a Pro2.

[biturbo15]

so hold on the pro 2 is better? is fiberglass better or worse than carbon graphite? How much will it cost me to get my sport 2 to turn into a pro 2?

[Philly's Finest]

The pro2 is "better" only in racing terms. It is the same car so it's not that much better. Graphite is lighter than plasic/fiberglass. That is why many race versions of cars have graphite because it's lighter and lighter means more speed. But it's also more brittle so it will break more easily as plasitc would generally bend.

However to someone just beginning racing or a basher it won't be noticable. My suggestion is that you learn how to drive the car well, before you start pouring money into hop ups. I've seen a good driver with an average car beat a average driver with a fully hopped up car.

Also the pro2 is no longer being made. You can still find option parts for it. They are direct replacement because they are the same car. So if you really must have better parts you can find them.

[tl01boi]

what do i need to convert a sport1 into a pro 2 wher4e can i get the parts

[tl01boi]

what do i need to convert a sport1 into a pro 2 where can i get the parts

[biturbo15]

so upgrading to the pro 2's carbon fiber chassi is something that I can do to my car. But as for now i should just work on learning how to drive my car better, and learn how to tune it correctly. Then later I should worry about lightening up my car. Well I plan to race soon but all of the tracks around me are outdoor and its raining often so that doesnt sound like it will happen tooo soon.

[rx78gp03s]

hey guys, remember me?
well here's my rs4 pro. i remember hearing that i can talk to here, sooo here it is with a custom saddle pack holder i made for it. enjoy

it has an esc that can handle stock motors, a p2k pro, 3000 cell's and a fubutaba radio. new rims + tires and a new rsx body i painted.


enjoy

[PCC]

Originally posted by tl01boi

Almost the entire car is different. It's cheaper to sell your car and buy a used Pro2 than to upgrade.

[tl01boi]

hey that rsx is pretty sweet just cut the body post smaller lol just kidding i just got a accord today and right after i got it badluck came i painted the first coat and forgot to put the tape to cover the windows so my windows are yellow now and i couldnt find my hobby knife and i didnt want to wait so i used sciccors and i messed up on the holes haha ill have pictrues soon its gunna be my bashing car now and the car i use for racing

[tl01boi]

okay i nahve now decided what to do with my sport 1 lol im goin to convert it into a pro 1 hah this works it said it on hpi sport2vs sport1 equals=total domination

[tl01boi]

by the way how fast is your sport 2 what motor are u using what gears and what esc

[biturbo15]

I took a rough estamate today. I ran a 9t double with 22/93. I went about 160 ft in around 3 seconds.... so that means I went 35 or so. But the thing is I was on a gravel road... I am going on road tomarrow armed with a stop watch and tape measurer so I will tell you exactly how fast I am going tomarrow.


did you say the sport 1 is better than the sport 2? is that true?

[rx78gp03s]

That is why many race versions of cars have graphite because it's lighter and lighter means more speed. But it's also more brittle so it will break more easily as plasitc would generally bend.

that is partially true. so if ur saying i have a 10 ton dump truck and its hauling 3 tons its goin at 35mph, then when i release the 3 tons, it'll go 40 mph?

lighter usually means getting to top speed faster, or in simpler form, a faster acceleration.

[biturbo15]

I thought that lighter ment all around more speed... Both in acceleration and top speed. It would make no sense for it just to change acceleration.

[rx78gp03s]

ull get a higher speed if its a huge huge load thats being taken off.

[biturbo15]

How much do your guys's cars weigh? with everything except battery? I shaved down quite a bit off of my rear and front shock tower and the plastic side plate / belt tensioner. I also took out huge chunks of plastic off of the battery holders. I will take a pic to show you all, but I need to get my bro's digital camera and he is on vacation :( maybe later.

haha no im not saying that i have the sport 1 and sport 2 both are good cars just about the same speed good handling on both

[PCC]

biturbo, the graphite chassis is stiffer and better for a smooth race track. The FRP chassis, being more flexible, is better for parking lots.

[biturbo15]

once i get money I am gonna upgrade to the carbon fiber chassi and graphite ball differentials. Then my car should be set.

[biturbo15]

hi guys. I had a little accident today... I broke my rear shock tower practically in half... I was wondering which of these two shock towers would be better to replace it with?

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLT82&P=7


http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNV53&P=7

[rx78gp03s]

i'd go witht he carbon fiber one
looks alot more trick and hey, u said u wanted to lose weight, well there's ur bonus.
good luck wit it.

[biturbo15]

the top one replacement one is carbon graphite... which is lighter the carbon graphte one or the carbon fiber one?

[rx78gp03s]

go wit the carbon fiber one.
u have more shock mounting options.
and honestly, i'd go for the trick look. plus its tons stronger hten graphite

[biturbo15]

cool ok. I will go with the carbon fiber one with more shock mounting options. I just hope it is lighter than my stock one.

[Philly's Finest]

Originally posted by rx78gp03s

Well I didn't word it technically correctly but then again we aren't talking about dump trucks are we? Nor are we speaking about tons. Ounces in rc can make a difference and shaving as much of them off as you can is important to some people.

Still common sense & basic physics would tell you that something with less mass will accelerate faster & overall be faster then the same object that's heavier. So in essence it IS true.

[rx78gp03s]

thats why i said "usually" and not "always"

[PCC]

Originally posted by biturbo15

biturbo, I have the graphite composite rear tower if you want it. Brand new, never used. You have to drive down to San Francisco to get it, though (actually, Daly City, just south of San Fran). I'll show you my Pro2, too. Email me if you are interested. As for weight, they're roughly the same, though you can use titanium or aluminum ballstuds with the graphite composite tower while the woven CF one needs to use the stock steel ones.

[biturbo15]

I think I am just going to buy it from tower. That is a little to stalker status for me.. no offense or nothing. And that is pritty far SF is like a 45 min drive. Plus I am 15... But thanx any ways. I am sure that I am just being overcautious, but better safe than sorry.
:D

[PCC]

No problem.

[biturbo15]

I am now upgrading to hand wound motors... Do you guys think I will see a big difference between my trinity speed gem 9t double and a fantom hand wound 9t?

[Prinler]

Hand Wound motors dont have that big of an advantage. In Rccar mag... there was an artical from Reedy or someone saying the quality of machine wound motors is getting sooooo good that you only have a small advantage. most is phsycological. The Ti and the d5's are both amazing motors too. i might try one of those.

[biturbo15]

I am gonna start a thread and see what people think.

[biturbo15]

I got my woven graphite shock tower and it is hella sick looking. I also think it is ligher than the plastic, I know it is a lot stronger.
But any ways I was wondering. Our car has plastic A-arms right? I might be wrong but I think they are plastic. Will upgrading to these help?

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNE47&P=K

[biturbo15]

what mph are u guys getting from your cars??

[truplayboi]

with the sport2, you can take off one of the belts to make it rwd or fwd right? will it hurt the car in any way?

thanks

[biturbo15]

you can but why would you ever want to??? It is much better 4wd. I have snapped one of my belts and it just makes the 2 tires that do work burn out a lot. You can try and run it if you want but I dont know how well it will work.

P.S. if you do I suggest rear wheel drive.

[truplayboi]

ooo :p thx

[biturbo15]

check out my post here. Tell me what you think of my new idea? Hope someone gets the idea and helps them also.

let me know

[biturbo15]

Thats great. How did you make it?? My esc doesnt fit completley on the chassi and hangs over. Just slightly but it does. How much does that weigh? is it lexan? Can I get one? LOL.

What option parts have u guys put on your cars??

[rx78gp03s]

rs4 pro car.
the only hop up i ahve gotten so far are rims and tires, but thats about it. the car already came with ball bearings and other carbon fiber goodies.
i guess a body is a hop up. also made custom parts for it, like a custom spoiler mount and a custom exhaust.

[Prinler]

I purchased a USB Hub from my work. Staples. It was a 2 pack for $19.99 good price. Well anyway there was a little bump on the back whrre the huge Transformers where. Its heat bent plastic. Look around for things you have purchase. See if you have a part that is large enough. I made to hole and scred it in with the front bulk head, then bent it down and mounted it where the top chassis plate screws in... its amazingly Strong. I will look around to see if i have any too. :) glad someone liked it :(


Also If anyone is interested in a 12 turn d3.5 speed gem pro(newone) 13x2 and 13x2 (the one before the pro) Also have a Futaba mc330cr I got a little while ago. Its only been run a few times, I went to brushless. Let me know

[truplayboi]

i jus got a trinity pk2pro motor and was wondering what would be a good esc and remote control for it. im looking for something thats not too expensive.

[biturbo15]

If you are looking to go cheap on radio and esc I suggest one of these two radios

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCTD2**&P=7

or

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXASX2**&P=7

good radios for really cheap.. as for an esc I really dont advise on going cheap on one. I suggest getting a top of the line esc. Other wise you will want to upgrade and you will realize you waisted your money on your first esc. You also need to decide weather or not you want reverse

Cheap esc with out reverse

hey I have a problem I have a 9t double motor and an intellispeed 8t reverse esc. but I dont go very fast. I timed my car and I go 100 ft in like 2.1 seconds that means I am only going 32 mph or so. Now why am I only going 32 with a 9t trinity speed gem pro? What speeds have you guys gotten?

[LanceS]

Also, if you're gonna stay around stock motors, I can suggest the Novak Rooster.. I have it and really like it, you can reverse disable also if your local track requires it.

BTW, the conversion of my rally into a 180mm Sport is done.. Thanks PCC for the extra parts, and with that and a few extra parts trees and short dogbones, and it's back on the track..

[PCC]

Glad I could help.

[torque5252]

I have an HPI RS4 Sport. I got a great deal on HPI front universals (half off) at my lhs, but they're short (for 180mm). I'm currently running a Sylvia body, and the car's built at 190mm. Are there specific HPI bodies that are 180mm? Cuz' if so, I can't find them.
I don't want to replace all my wheels with more offset ones, but I do want to run these universals AAAGGG what to do.....

[rx78gp03s]

well i got an rs4 pro and it comes to about 185mm. measured it, and thats pretty normal with the universal joints. i bought an rsx body and realized how deep inside the body was soo i bought the 26mm, 3mm off set y spoke rims with the 2 mm spacersfrom hpi. that only made my car 195, but noiw it looks right.

that is the cheapest way u can get to make your car as close to 200 as possible. or you can try to find another deal at ur lhs for the nitro version of the unijoints for ur car. but the rims are the only way i could think of with out buying a whole new set of uni joints. plus u can get tires to boot to match. :D thats wut i did

and how tight my car looks with them rims :D

[biturbo15]

I have that style of wheel on my car now too. But I painted them black ...

[LanceS]

The conversion can be done. In fact, it's shown how to do in the RS4 Sport instructions, and that's where I got my inspiration to turn my 200mm rally into a 180mm sport (that and the body my wife got me for xmas). For the most part, it's just using longer suspension links and dogbones. There are a few other minor issues, but the best thing to do is to go to HPI's website and print out the additional instruction set and compare it with your originals. That's what I did, and believe me, if you have a sport or pro to start with, it's much easier. The rally shares most parts, but I still wound up having to get about 3-4 parts trees to finish it off right.

[truplayboi]

i have a lrp runner esc with a trinity p2k2pro motor. do i need to install the capacitators for the motor and would i need to cut the wires to solder them on the motor??

[jj212jj]

I want to get a Sport 2, I was looking at a 4tec but the kits aren't available now. Would you guys recommend the Sport 2 over the Tc3 or any other model? But here are my questions on the Sport 2. Will this ESC work? http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXRE95&P=K how about this remote http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNR85**&P=K and also what kind of motor should I look at getting, And pinion, spur gear set ups? And a new set of tires which ones are good? I plan to just bash on the street with this car, no off roading becasue I have a t-maxx for that. Is there anything else I need to look at getting to make this car run great. I don't plan on doing any racing maybe just a few races with friends, mostly just parking lot or street driving. Also what kind of batteries are good? Thanks

[Doh Boy]

thanks to a wonderful idea from NitroCrackers, i was thinking about what would happen if i got a Trinity monster maxx wild or pro and stuck it into my Sport2. Ill probably be usin 7.2 volts at first, but i might find a way to get a second stick on. and of course, im gonna gear LOW. just wondering what u guys think of it.....

[rx78gp03s]

i like the idea
will an e maxx titan motor fit in an rs4 pro/rs4 sport? if it can, then i will do it

[Doh Boy]

I think it'll fit...barely..and only if u gear REALLY low.....but then again, why would u want to gear high with a motor that produces ludricous amounts of torque;) ?

Im just wonderin if the performance will be good even with 7.2 volts....i dont think the extra stick of wieght is worth it......

[biturbo15]

YOu would need stiffer shock springs to hold the weight of the extra battery. Also your car wouldn't handle as well. It would be cool to try though. tell us what happends.

[rx78gp03s]

which motor should i get...i plan on using only 7.2 volts....14.4 is too much weight.....

the trinity monster maxx motors? (550-size, probably 17 or 19 turn)

or the associated BaddMaxx motor? (540-size, 19 turn)

remember...performance using 7.2 volts

How did you get that rear wing? Do they have other ones also? I dont like how my wing looks and was hoping to get something cool.


Doh boy
I Would get the 540 because it is smaller and may fit better. I may be talking out of my butt though.

the rear wing came with my body. the spoiler mount, a friend made for me. alot of the stuff on my body is custom made. you really can't see it, but i got custom exhausts too.

Hi,

I am currently racing my Sport 2 on a carpet track at my LHS. I have good traction and run a saddle pack.

I am having problems with the car rolling in the corners. I have tried different spring and setups.

Any suggestions from anyone?

Thanks

Gabe

[biturbo15]

You have to take the courners slower lol. slow down right before the turn, then on your way out accelerate again. maybe anti sway bars to reduce the amount of shift in the chassi. Maybe the hpi sport 2 handling kit. I dont really know usually flipping is more driver than car. Hope that helped.

[biturbo15]

someone say something! this is a good car.

[rx78gp03s]

i'm agreeing with u bit turbo.
well here's a pic of my new chassis, the ob4 pro II international
next to my hpi rs4 pro.
bonus points to someone who can name what shocks are on the ob4.

[rx78gp03s]

the ob4 is my drift car. or maybe just my concourse chassis now.

Umm, you haven't seen my collection, yet. Let's see, on-road electrics only, I have two XRays, a Pro, Pro2, TA03, and a TC3. Yeah, half of them are for sale but there you have it.

[Grifter]

Is there a big difference between the Sport and the Sport 2?

Thanks!

[PCC]

The original sport is the same basic chassis as the electric Rally. The Sport2 is a FRP version of the Pro2. The main differences that I can see are the saddle-pack chassis on the Sport2 and the straight shot of the rear dogbones (the Sport rear dogbones are canted backwards towards the rear wheels while the rear dogbones on the Pro2 and Sport2 are pointing straight out at the rear wheel, meaning less friction at the joints).

[Grifter]

Ok, thanks.

Hello,
I was thinking of getting a touring car just to start racing on road and bashing around because i have only owned and ran trucks. I was thinking of getting a sport 2. But i wanted to know if i could keep it pretty much stock and still get some desent performance. Also how does it handle high power motors such as BL motors of 40+ amps.

[biturbo15]

Ask prinler. He ran a huge brushless motor with a bunch of cells on the sport 2. I dont think he had many problems. he is on page five I think.... big pictures of a big brushless motor.:D

[Philly's Finest]

Are front and rear arms the same as in interchangeable?

I think that the Sport 2 is a great place for people to start. It has the aftermarket support you need for the car to grow as your skills improve. Stock, it performs well and may need only a few parts to stiffen up the chassis. A freind of mine has his converted to a rally type car, which wasn't hard to do if you choose to go that route.

[Grifter]

Is there anywhere, besides eBay, where I can purchase a Sport Instruction Manual?

I dont want to download it off HPI's website, and right now ebay doesnt have any. Shouldnt they sell them somewhere?

Thanks!

[Grifter]

When converting the Sport to 200mm or 190mm, is there any items that have to be bought. I looked at HPI's instructions on their website and it looks like there doesnt. It seems like only tie rods have to adjusted, etc.

Sorry for all the questions.

Thanks!

No, the front arms are different than the rear arms and they're not interchangeable.

You will need the longer dogbones. Also, if you cut the rear arms (like you're supposed to) you will need new arms (HPI arms come in sets of one front and one rear). After that you just need to adjust your turnbuckles or tie rods.

Here's why:
See tree #A452...the ones on the top are the front arms.

Why do you wish to swap the arms in this manner?

[jetbullet]

what is a good motor "Stock" which goes best with the Sport 2?

[Champ29]

How do you raise it up off the ground

[tamiyadude]

Hey guys, I'm thinking about getting a sport2 kit to go along with TL01's but was wondering.... is HPI getting ready to axe the sport2??? Thought I heard something about that a while ago and I don't want to buy something that's hard to get parts for.

I don't want to race this car, but just wanted a different chassis to mess with and I've got some TL01's and had a TC3 already. Actually I'm torn between a TA04 and a sport2. Only HPI I ever built was a NMT and I liked it alot.

please help :confused:

[tamiyadude]

I don't know if the sport2 is dead... but I know this forum is dead. :D

I ordered my sport2 kit last night.... Nissan Silvia

-TD

[Grifter]

I think I've aske this before but I dont remember what the answer was.

Are some parts for the Sport 2 interchangeable with the Original Sport? i.e: Upper Chassis, Shock Towers, etc?

Thanks!

[tamiyadude]

I don't know grifter and don't hold your breath getting an answer. I haven't got my question answered from 10 days ago :(

This forum is pretty much flatlining_______________________

The front bulkheads from the bumper to the upper cover are the same. The diffs are the same as are the dogbones and axles. The front hubs are the same as well. The rear bulkhead, motor plate, side support plate, diff, spur gear shaft and pulleys as well as the rear belt are the same. The rear dogbones are the same as are the rear hubs and axles.

The upper and lower chassis are different. The suspension arms and front carrier are different. The shocks are different, though interchangeable (I may be wrong on this one, did the Sport come with aluminum shock bodies or plastic?). The rear shock towers are different. The front belt is longer on the Sport 2. Both upper suspension arm mounts are different, front and rear.

Any other questions?

[PCC]

tamiyadude, I don't have an answer for you about the Sport2 being discontinued. I sure hope not, I need to have a supply of parts for my aging Pro2.

As for the question about Sport2 or TA04, I think the TA04 is a better car, though it is more expensive to hop up (I'd go for the top-of-the-line model and go from there, it's actually cheaper to do that than to get the TA04 or TA04S and to fix it up).

[tamiyadude]

PCC, yeah I atleast hope the parts stay around. I ordered a sport2 kit from Tower a couple of days ago.

Bad thing is, day after I ordered my sport2 I discovered that new HPI Electric Super RS4! I'm trying to find a way to buy one overseas and if I can, I'll be returning the sport2 to Tower for a refund (I'll just lose out on the shipping it back to them).

I don't race, just play around the parking lots and I think the Electric Super RS4 would be a better choice for me. Should have a hair better ground clearance to clear small pebbles that the sport2 would hit on a unprepaired surface like I run on. Plus the thing is soo big, it's just cool!

If my friend in HongKong can't hook me up with a Electric Super RS4 I will go ahead and build the sport2.

[Grifter]

Thanks PCC!!!

Hi all

I need some help setting up my RS4 rally for onroad. The pic is the result of my latest try at getting it right. I am running a 1/4" spacer inside the Rear shock with 60w oil and 3/8" spacer in the fronts with 30w oil.

The Red spring is rated 58.8 gF/mm and the rear has the stock Black at 67.2 gF/mm

I tried a heavier spring in the front with 60w oil and could not steer. The Heavy spring is rated 78.4 gF/mm

HELP - any ideas on adjustments?

oops what is the problems

[jetbullet]

can someone help me with this problem

[_SC_]

I know it said 6 cell but would a 7-Cell would fit? :confused:

[Philly's Finest]

You can make anything fit with a little creativity!

As a saddle pack you just have to put one of the cells on top of the others. If your gonna use the stock battery pack holder and a stick pack no it won't work.

However if you really want to run a 7 cell stick pack just use velcro to secure the battery down instead of the stock stick pack holders.;)

Just get creative and some velcro from the hardware store & your set

Can you add breaks to a sport 2?

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.
