The RS4 Pro 4 will be a radical departure from the RS4 Pro 3, offering a change of concept for HPI both for suspension geometry & transmission. Extensive track testing of all existing electric 1/10th scale touring cars & HPI prototypes has already been done, the all-new RS4 Pro 4 is the result of that testing.


http://www.rccaraction.com/pics/pro4/pro4side.jpg


The Pro 4 features big changes over the Pro 3... new drivetrain, new suspension, and new steering geometry. Consistency, tuning options & drivability have all been dramatically improved. The most significant change is that the Pro 4, at the requests of our drivers & customers, uses a shaft drive transmission. Track testing revealed the benefits of low maintenance & fast acceleration that a shaft drive transmission offers. Again at the requests of our customers, the RS4 Pro 4 will be supplied in self-assembly kit form with key items like the radio, ESC, body and tires left to the choice of the driver. The Pro 4 will use the highest quality materials & will have a high standard specification to make it a force at the highest level of competition.

Our team drivers will be racing the Pro 4 at all major electric touring car races around the world by the end of the year, ensuring factory support and continued development of the platform to keep up with the latest racing technology.

i told you i saw it :rolleyes:

[nomac]

when. i want......

[wanchaiwarrior]

well, Ive been trying to decide on the next car after my TA04SS, and this looks like it !!!

Gotta get it when it comes to Hong Kong !!!

Only question is, will I be able to run it with a stick pack ??? Dont have the money, skill or tools to make battery packs.

[wanchaiwarrior]

either that or the R40.......hehehe

[TRF Drive Hard]

Sorry to say but thats a tb yoko evolution tc3 freak... its the same basic shaft concept... i really dont see anything "new" about it... although it is a HUGE jump from a belt design...

[Nightz]

How come even the next generation "Pro" kit still has locked rear toe settings? I thought this was a pro level kit? Shouldn't they have used turnbuckles back there also?

[sosidge]

Nope, turnbuckles for toe-in are a pain, very hard to set evenly without a setup station, and the toe changes when you adjust the camber angles. Blocks are much easier and no less effective.

[Maxxcrazy]

chassis looks soemwhat like a durango (german 4wd buggy for those who don't know)

[Godspeed]

The Pro4 looks very much like the MRC Academy electric touring car.

[puribong]

yeah this car looks kinda like combination of MRC Academy STR-4 Pro and Tamiya EvoIII.

[FSU427P]

Even though the chassis looks very much like the TB Evo III, the MRC car, the TC3 (shaft, motor, and battery placement), and the new Yokomo car, it doesn't matter. What matters is the fact that HPI is making a real effort to produce a car that can be deemed "worthy". It's about time they listened to what we want in a car, and now that they have finally delivered (picture-wise for now), it'll be interesting to see what the car can actually do. The car may not set the standard, but for HPI people, this finally gives them something to brag about.

[Saboteur]

He's right. Still HPI has done some good work. The R40 and the Pro4 are sure to be hitting the tracks soon once they are in the LHS's.

[wess]

with a shaft driven car, there's only so many ways to place electronics and batteries. all shaft drive cars will have a motor on one side and batteries on the other, it's the only practical way to balance the chassis. so just because they have the same chassis layout as other cars out there, it has nothing to do with copying designs.

i'm glad hpi moved towards the shaft driven tranny.... hopefully xray will follow suit :D

[wess]

sorry, my last post wasn't directed to anyone here in particular. hopefully nobody will flame me for that:(

[Dino the great]

This is what the pro 3 should have looked like. If this thing is going to be priced competitively, it may be a big comeback for HPI. It actually looks kinda like a shaft drive PRO 2!

[neongtr]

looks like shaft drive type is coming back to high end racing.

[rcharry]

That makes me mad, i had a pro 3 and it SUCKED!!! I spent like 200$ to make it all carbon graphite and it still SUCKED! Then they get this new kit and its all woven graphit!
GERRRRRRRRRRRRRRRRRR!

[Dino the great]

You wasted 200+ dollars trying to make your pro 3 not suck? heeee heeee! (belly laugh)


I feel for you man, I did the same thing with my Nitro RS4. You know whats gonna happen, we won't buy HPI cars because we are mad, but other guys who never owned one will and then still beat us at the track. Ironic? The same emotion that made us stick with HPI before and suck will make us suck still because we don't have them now that they are improved. Anyone following this? eh?

[Nofri]

I also asked this question for the R40, but since I am choosing between a nitro or a electric car as my 3rd car I gonna ask it here to :D
Whet is the Pro4 availble in the shops? Also like the R40 in October?

Tnx

[neongtr]

owning a HPI Micro RS4, I quite like the quality of HPI's car. However, I am still the fan of tamiya. So TB EVO 3 will be my chioce over the Pro 4.

[ChumsGum]

Hats off to HPI for listening to the people and delivering a true "PRO" car and including all the good stuff out of the box.

If I were to purchase a touring car though, I'd go with that new Yokomo car. That new silver graphite chassis is a magnificent work of art and engineering.

Who knows, maybe HPI will counter with a purple graphite chassis. You listening HPI?

"Delivering" a pro car? I think the word you are looking for is "drawing".

If HPI REALLY wanted to bring out a shaft drive car, they could have done it a year ago, considering the number of prototypes they had been showing and racing.

But my gut feeling is they don't REALLY want to bring out a shaft car. I would say it's even-money that the Pro 4 never appears.

[Frank McKinney]

*waving cash*

I'll take that bet, I can use easy money.

[Nitro Fans]

I'm sorry but I really can't understand why whenever there is a new shaft-driven vechicle, people will say xxx-version TC 3. yokomo one to me resembles tamiya evo 3/2 much more than the asso one. So does the hpi now. Tc 3 isn't the first shaft-driven EP vechicle anyway, there is no reason why it is always the "gold standard". Of course, personal opinion only, sorry to all royal asso fans.

Ya, *** (W for WHO) cares about what the cars look like?

and on most hpi cars, you can take the front C hub carriers and knuckles and put it on the rear. It doesn't really matter if the rear toe is adjaustable, unless you are in the tuning level of international drivers. (which I highly doubt, determining from the way you type)

The reason why its the gold standard is because its simply the best shaft driven car. Look at any one of the numerous comparisons of shaft driven cars and tests on the TC3, not to mention the winners circle at numerous big events in the last few years and the TC3 is the shaft drive that wins. Associated put in loads of engineering and testing into the car. Instead of just slapping out an annual version, they update it as needed which is why 4 years later, it's still state of the art. Its the gold standard because everything else is silver or bronze.

[DrDiff]

I totally agree with HauntedMyst! You don't see a "insert name of big race winner" edition TC3 or B4 comming out of Associated. They just make rolling changes as needed. How many versions of the Pro3 did HPI offer around the world? Yes it is true Associated failed on its first 2 attempts at touring cars [narrow pan car, and narrowed aluminum tubbed RC10] but they finally got it right. HPI had it right in the first place and then due to poor materials choice, got it horribly wrong.

[Frank McKinney]

The different Pro 3 versions were to respond to market demands - the 'normal' Pro 3 was released in US and Europe, the Spec S and Spec V were released in Japan to start with also, then the Hara edition was released in Japan after the options were available. You can compare the Hara edition to the Factory Team version from AE - full option everything. Even AE waited to release that after the parts were available. The Racer and Team version are similar (in parts loadout) to the Spec S and 'normal' version Pro 3. So there shouldn't be any gripe about various versions of the cars - most companies do it.

And Associated didn't attempt to make a touring car with the DS and the narrow pan car (forget its name at the moment). Depending on who you ask, those were just market fillers or surplus parts sales. The narrow pan car (ROAR class: Touring T-1) was just a bad idea to begin with but other companies like Corally tried to get it going as well. It was never meant to compete against full suspension 4WD cars.

Anyway, all this is in the past. The Pro 4 is in the future.

[DrDiff]

Please forgive my ignorance but I thought T1 rules was for 2 door FIA GT coupes on 4wd chassis. T2 was 4 door sedans on 4wd chassis.

[Frank McKinney]

You'll have to find a copy of the 2001 or earlier ROAR rulebook (or possibly 2000 and earlier) - I just checked and apparently they saw the light and deleted the Touring T-1 class from the 2003 rules completely.

I'm fairly certain the class required 4-door bodies like the Touring T-2 class but I think it was meant to bridge the gap from pan car to 4WD touring, similar to the 1/8 scale .15 class or the 1/10 scale .15 class (both of which were similarly deleted from IFMAR competition). Because of the quick adoption of 4WD touring by the masses, the Touring T-1 class was probably considered redundant by ROAR (it was never IFMAR approved) and therefore removed.

And that concludes the lecture... haha! :)

[DrDiff]

OK then is it IFMAR with T1 rules for 2 door coupes and FIA GT's and T2 for 4 door sedans?

I KNOW one of them had a class for the 2 dour coupes and FIA GT's!

[Frank McKinney]

NORRCA did (and may still) allow 2-door car bodies in some of their touring classes.

[RC-ZOMBIES]

Frank..

Will we see a Hara edition Pro4 kit after the initial release? I'm almost certain we'll see one....:D

[Frank McKinney]

I don't know...the standard Pro 4 will come with a lot of good stuff out of the box already: Ti turnbuckles, alum. CVD's, carbon graphite plastic in everything, carbide ball diff, front one-way, alum. threaded shocks, alum. drive shaft, spur gear mount and motor mount, alum. hex clamp hubs, etc. What else is there to add?

Yes...the STD Pro4 is full of goodies already. Seeing Hara's past cars...
Front alum. lightweight body post...as seen on Pro3. :)
Aluminum arm mounts/rear toe-in blocks..:D
Finned motor heatsink.
Woven Graphite upper bumper support.
Purple Aluminum battery brace and mounts.
Alum./graphite drive shaft.
Hot bodies will probably come out with these...:D

[Frank McKinney]

Oh yeah those are some decent options but to make the car perform the stuff will be in the box for that. For durability you can go with alum. mounts but otherwise the rest is eye candy.

[DrDiff]

If it truly has all the go fast goodies in the box! Then perhaps the first version of the Pro4 should be the Hara signature edition!

Not enough purple to make it a Hara Edition. :D

I'll bet WE won't see a Hara edition, but Japan will.:mad:

I don't think so either....but we'll have to wait and see...HPI got a lot of complaints when the Hara Pro3 was released not being available in the US. Maybe HPI will not make the same mistakes.

[mugenseike]

It might have some very very minor changes from this proto well since these pic's were released in 2002.
-mugen
oh and frank if you need some more info about the pro4 just remember i'm a pm away. http://www.gamers-forums.com/smilies/contrib/anym/pump.gif ;)

[rcharry]

I think HPI cares more about winning national and world chamionships then thier consumers!

[TEM]

I agree with Rcharry..... Why?, by the time I knew there was free replacement parts update for the Pro3, I called HPI for them. It was long distance and I was put on hold forever. When I got though they told me I was too late and if I wanted them I would have to go buy them myself! The US pro3 wasn't designed to win anything! The hara pro3 doesn't even resemble a pro3, except for maybe the spur gear, antenna tube and a sticker sheet?

When Tamiya found out there was a problem with the TA04R graphite tub, they gave us all new update ones for free! I mean as if HPI didn't know there were problems with the Pro3 chassis over top of the other little problems.

If you refer to the postings I made in the other HPI pro4 forum you'll know the rest of my story. My pro3 is still in brand new condition cause I don't run it and it simply sucks!

I'll go pro4 if HPI is willing to give me a trade in on the Pro3!..

Based on the pictures there are already things I'd like changed on the Pro4. And I'd hope they do a good job desiging parts that fit together with minimal slop(for the 1 millionth time, I hate slop!). We'll probably see different versions too. It looks to be a good design but i won't see it as a miracle machine to beat everyone else. At best it will be competitive anyways.. But we'll have to just wait and see.

[rcharry]

COOL TEM! Im glad you said that.
THEY WERE GIVING FREE PARTS AWAY!!! ***, i spent like $100 just on a-arms. F**K HPI!

I think they got enough compliaint and threats, to finally make a good car and hopefully improve there custormer service!

[IanMan]

class T-1 WAS for 4WD sedans with two-door bodies. ROAR never sanctioned any type of "pan sedan" class. It's quite a shame too. The cars are smokin' fast on anything better than a dirt covered, crack infested parking lot.

[aspiringrcracer710]

any word on a release date Steve?

[S15Racer]

*Still chomping at the bits*

When am I gonna be able to get one? The R40 comes out in august right? So the Pro 4 soon after that? Before Christmas? Any faint idea would be greatly appreciated:cool:

[S15Racer]

Ah man! I was totally set on a pro 4 till I looked at the new issueof RCCA. That new Yokomo is awesome! Now I cant decide between them. That silver graphite is dead sexy but I like purple better than blue...
guess I'll just have to wait for the full test of the pro 4 before I decide:D

[nomac]

dude, a friend of mine has TWO of 'em!he runs a brushless set-up in one and a stock set-up in the other. he says he bought two so he can have a back-up car?! the things are so smooth and quiet that you can hardly hear it running!

he's looking at two more "new chassis's" and me thinks he's going after the barracuda R2's. if he plans to sell i'll let you know.

[S15Racer]

Yeah, very nice cars they are, but a bit over priced IMO, $330???
I hope the pro 4 is less than that. Hey, come to think of it, how much was the pro 2? Cause the Pro 4 is similar, in equipment and matirials, to it so it should theoretically be about the same. Prolly a little higher for the front oneway and carbide rear diff and the Ti turnbuckles n stuff. But not much higher...

[nomac]

i agree. the car may sell for $219 or so.

[S15Racer]

Hey nomac, I never thought we'd be seeing eye to eye;)

that low huh? wow, I was just hoping it would be under $300! I was under the impression that the pro 2 was quite a bit more expensive than the pro 3 (for obvious reasons:rolleyes: ) Man that makes it now competition between it and the yok, $100 cheaper...

[ALJR]

any one in need of some nice new purple aluminum touring car shocks?

[nomac]

great minds think alike! (he,he). the pro 4 just might be more.(forgot that it may have more anodized alloy parts than moulded plastic/composites). the chassis puts me in mind of the str-4 pro from academy/mrc. and it's street price is in that neighborhood.

man! i really don't want to buy ANOTHER tc-3! i need another race car for cleveland and i want the pro4 to be it! (sigh).

[S15Racer]

Academy STR-4 Pro- now that was a nice car. I wanted one of those too, but didn't have the mula$$$ at the time. Yeah that is really similar to the pro 4, except the motor/ batts are swiched sides. But theres only 2 ways to do it right LOL.

Acually I've never had a shaft drive TC before, anything I should know that I might not be familiar with from belt drives?

[nomac]

yep...the belt cars seem to launch in a straighter line than a shaft car. the shaft tc's have slight torque issues under heavy throttle. some are more than others, but generally they're all very minimum.

oh...and the shaft cars accelerate better too. just less drag in the drive train. some people say there's no difference but which have a lower coefficient of drag ; self-lubricating gears or (rubber) belts?
nite for now.;)

[JIMMYBANGBANG]

i am iffy on buying the PRO 4, I DIDNT BUY THE pro 3 cause i didnt think it was any better than the PRO 2. actually i think the PRO 2 is one of the best touring car made by HPI. i have seen and ran the TC3 and didnt like the way it handled compared to the old PRO 2. if the new PRO 4 will be BETTER THAN the PRO 2 then i am all for it.

also i agree HPI with there consumer support sucks royall ass. i have called them once about a simple question to actually see if they have any knowledgable people in there staff and they couldnt even answer a simple gearing question.., if they cant answer that question what will make me think they could help me at all? i think if any of the companies provide true consumer support then there cars will be supported as well.

I WILL ALSO LIKE TO SEE IF ANY OF THESE COMPANIES WILL ACTUALLY SUPPORT THE MILITARY!!! put up a support our troops sign on there websites or something, or hand out some free kits to military members coming back from over seas...come on people you wouldnt even own a R/C car if it wasnt for the military protecting the right to even own one!!!

You're the one that sucks. Gearing is different for every car. It all depends on your motor, batteries, tire size, track and feel.

Also, sounds like you're one of those people that wants something for nothing. If you like your PRO 2 so much. Go grab an X-ray.

This forum is here to help people not BASH WITH CAPS!!!

lap you later...lololol what a geek. does HPI give you any money for you to back them by any means? and you are wrong you can give a simple range for any newbie to follow for gearing and they can move up or down a couple of teeth to be just right. if you havent noticed there has been soo many threads started just cause of over gearing problems..to me that sounds like a question that needs to be asked..maybe HPI needs to educate there staff a little better to please there customers..oh wait thats right you never asked any body for help when you first started..hmmm jerk

and by the way i had the final gear ratio for my car and the track conditions and just about anything else i could imagine to help them out to do there job.

and if this forum was here to help people then why dont you??? all these kids come up on here asking where and how they can get a nice R/C kit to start off..and where does everybody send them to??? exactly all these companies are making big buisness off of uneducated newbies...and these soo called uneducated newbies are the ones supporting your so called non profit hobby..so yes if i see a problem arrising in a company that feeds off of kids and peoples hobbies and enjoyment you are damn right i will be complaining and wasting my time to ensure i am getting my moneys worth.

till you pay my bills or give me a free kit dont tell me i am one of those people that want something for nothing, i work very hard for a living and i probably dont feed off of other people for a living either, actually you feed off of me each time you go out side and play with your car or watch T.V. or even cry to your mother.

lap ya later...what a joke

[NMT_RACER_BOY]

After what HPI had to go through because of the Pro 3
i think the PRO 4 will be good.

Downforce is right about the gearign it can vary depensing what condition you run in.


O, and HPI did send stuff to american troops deployed in iraq. Magazines, chips, food and stuff. IT wasn't much but you don't see other companies doing that

hmm they gave that out in the desert??? man i must have missed that one..lol i am not asking for anything what i am wondering do they support the fight over seas? if they do why dont they post up some support the troops icon that many sights have on there websites.

support isnt always money or materialistic things, it can be as easy as just saying thank you. i am a person that will not buy anything from a comapny that does not support there own troops, that tells me that if the company dosent even appreciate the small things then how will they appreciate there own customers!

and to answer your gearing question, if you supply me with your final drive ratio and the conditions of the track you are running on (tight track or long straights) i can give you near the range you will want to be in. i have been in R/C now since i was 13 years of age and now i am 26 years of age, i know about gearing. that wasnt the point in my post, if you have noticed i called them on a SIMPLE gearing question. and i am sure if you browse this website for how many gearing problems arrrised in the threads you will be amazed..and that is something simple to teach. if you want i can tell you exactly how to figure it out on your own..it is actually very simple. but i also do understand not many people can grasp the info.

[S15Racer]

JIMMYBANGBANG- the fact of the matter is, that no matter how relavent or thoughtful or right this whole rant is, its out of place in this forum. This is all about the HPI RS4 Pro 4, its mostly speculation right now, but when the car comes out, it will be more useful as a tuning tips and racing info thread. So please dont go and get it deleted before the pro 4 even comes out.

:rolleyes:

[nomac]

Amen!!!!!

[NMT_RACER_BOY]

ME WANT PRO 4!!!!


I wonder how long till we get production photos...

[S15Racer]

too long:rolleyes:

Lets see, the R40 seems to be a couple steps ahead of the pro 4, and its being shipped out for sale, or so the HPI site says. Its pics were out months ago so Im guessing the pro 4 pics will be coming within a month or so... But thats just a guess, I have nothing solid to back it up:(

[iceracer6x]

Went to hpi forum and they said it would be out in late october but anything could set it back

[S15Racer]

You got an answer from the HPI board? Surprising:rolleyes: Wonder if it'll be out earlier then, since the R40 is/was ahead of schedule

[S15Racer]

The STR-4 Pro seems most similar to the Pro 4 than any other TC on the market, so I'm kinda thinking in print here:D trying to figure out the pro 4's price:

Major similarities:
Graphite plate chassis
aluminum motor plate/rear shaft mount
aluminum threaded shocks
composite bulkheads and suspension parts

Major differences:
Pro 4- aluminum drive shaft/STR4 graphite
Pro 4- Titanium turnbuckles/STR4 aluminum
Pro 4- front oneway/STR4 dual diff
Pro 4- Carbide ball diff/STR4 standard
Pro 4- MIP CVDs/STR4 universals
Pro 4 is slightly more adjustable than STR4

Price of STR4 Pro- $219
My estmated price for Pro 4- $240-$250

Does all this sound reasonable?

Hey, do any of you no what type of motor is going in this? With 3300 batts about how fast is this expected? Being new to the onrad electric about what is the expected price. Also would the novak super sport brushless system be good in this? would it make it fly? Is this a RTR or Kit? thanks a lot guys. sorry. new to the electric onroad and saw a pic of it in RCCA and thought it was aweosme. thanks

[nomac]

i think i just spotted my next touring car! droooooooolllll!

(i'm in love!)
hey 15......do you see this!?

[S15Racer]

Just a sec nomac, gotta wipe all the saliva off my keyboard:D

[/breaks out of mesmerized trance] What huh? Ok I'm back. Allright lets see, theres no motor with this its not RTR. Speed would depend on your motor and gear but it should be in the nieghborhood of Realfriggenfast. No one know the price yet but look at some other posts ^ for the estimates. I imagine the shaft drive would handle BL systems rather well. Um its akit. No problem we think its awesome too.

;)

[S15Racer]

OK last post I promise!

Man that thing is sweet. Its so simple! Just a front gearbox/suspention and a rear Gearbox/suspension bolted to the chassis plate. I could prolly build it in 5 or 6 hours! hey seaking of building it, what size hex drivers am I going to need? I've got 1.5 2.0 and 2.5 mm. Will those do? Now looking at the pics again, theres no purple CVDs, bummer oh well moving on. I wish there was a better pic of the steering system. Boy those are some sweet looking shocks its got. I'm glad their aluminum, cause the cap threads on my pro 3's rear shocks are stripped and they leak like mad. It truely is one of the simplest cars I've ever seen. Looks like each gear box is made of just 2 or 3 main parts and just bolted directly to the chassis. Not the overly complex set up in the pro 3. One last little interesting bit, why are the steering/toe in links attached to the bottom of the knuckes?

Ok thats really all for me...:D

[nomac]

yes, i'm dragging my knuckles....mope, mope.

*oh yeah, maybe it's for bump-in or out adjustments like on some off-road cars. but onlt not as drastic.

[puribong]

if you order from directly from MRC site, www.modelrectifier.com
STR-4 is only $199.
yeah STR-4 pro and pro 4 does look very similar.

STR-4 features

Independent wishbone suspension
A full complement of 21 ball bearings for speed and durability
One-piece carbon chassis for minimal flex
Two-piece carbon upper deck delivers excellent rigidity
Front and rear adjustable ball diffs
Efficient carbon shaft drive system
Hard anodized threaded aluminum shock bodies and color-coded shock springs
Accepts stick or individual battery packs
Front and rear CVD shafts
Choice of 4 different 48-pitch spur gears
Dual layered, foam supported slicks included
Adjustable camber and caster rates
Many stylish purple anodized aluminum parts

The STR-4 Pro seems most similar to the Pro 4 than any other TC on the market, so I'm kinda thinking in print here:D trying to figure out the pro 4's price:

Major similarities:
Graphite plate chassis
aluminum motor plate/rear shaft mount
aluminum threaded shocks
composite bulkheads and suspension parts

Major differences:
Pro 4- aluminum drive shaft/STR4 graphite
Pro 4- Titanium turnbuckles/STR4 aluminum
Pro 4- front oneway/STR4 dual diff
Pro 4- Carbide ball diff/STR4 standard
Pro 4- MIP CVDs/STR4 universals
Pro 4 is slightly more adjustable than STR4

Price of STR4 Pro- $219
My estmated price for Pro 4- $240-$250

Does all this sound reasonable?

[JIMMYBANGBANG]

i dont see why the PRO 4 wuld be over 219 dollars. look at the TC3 and the PRO 3 when they first came out, although they might try and hype it up a bit, but i guess we will see. i dont see why the PRO 4 will be worth 240 dollars, what makes it more expensive then the TC3?

[S15Racer]

We'll my thought was that since the pro was around $200 when it first debuted and the Pro 4 is much more well equiped than the pro 3 (ti links, front one way, rear carbide ball diff, woven graphite plate) the starting price will be higher. If I recall correctly the Factory Team TC3 was around $250-$260 when it first came out. Not to say I wouldn't mind being wrong about this. It would be awesome if the Pro 4 was only $219:D

[nomac]

what a shame! we're all ready to buy this thing and HPI is being iffy on it's release!:mad: WHEN WILL IT BE AVAILABLE!??!!

It's be a long time coming, but i want to race a RACECAR that's not one of the "big two"

[Stoned teenager voice] Sweet, sweet [/Stoned teenager voice]

:D Nice, looks a bit stock though;) Hey Zombies, I've been wondering, with all the goodies that come with the stock kit, what more are we expecting from the hara edition? All I can think of are purple cvds and a cf battery brace, oh and aluminum body mounts...

Purple CVD's come standard.. for now anyways...

From HPI:
Main Features:

Woven Graphite Main Chassis
Woven Graphite Upper Deck
Woven Graphite Shock Towers
Woven Graphite Steering Plate
Purple Titanium Turnbuckles
MIP CVD's, Purple aluminum of course!

CF battery brace...most probably molded type..since the all molded parts will be Carbon reinforced.

This is just my best guestamate for the Hara edition kit..
>Purple aluminum front body post
>purple aluminum arm mounts
>purple aluminum servo / transponder mount
>Purple aluminum battery brace
>HB Delrin diffs.
>Purple shock bodies...
>Ti screws....
>Purple aluminum camber link mounts.

there's not a whole lot you can really add to the car for performance... most of the Hara stuff is eye candy.

[S15Racer]

Are you sure about the purple cvds? Cause the CAD drawings had them, but the real pics of the prototype do not...

:confused:

[RC-ZOMBIES]

Well...that's HPI's original quote on the Purple CVD's...
that could change when the kit get's released.

HPI also stated: "specification subject to change"

[Downforce]

If color is going to determine performance...then what would be the fastest color? Just wondering!......I don't want the slowest blue car out there.

[RC-ZOMBIES]

All the LHS here in Michigan have been told end of September. And a price around $200-250. And you can preorder them right now. I have 2 on order now. They'll be out way before December here. In time for Cleveland.

All though $200-250 seams a little low for this car. I don't care as long as it's out in time for Cleveland. I don't want to get a TC3 for one race. Yuk!

[S15Racer]

Has anyone asked HPI? ;)

$465 seems a little steep [/understatement]

$250 is more what we were expecting. Maybe its just one of those things where the price is outragously high until the kit acually goes on sale, in which it goes down to the real price. Or maybe rainbowten was using the list price as a base figure.

Whatever it may be, the pro 4 cant be $465, that more than a friggen Tamiya evo 3! And if it is that much, I'm stickin with my pro 3

I talked to Thad last year at Cleveland and at that time they wanted it out for Cleveland this year. So far everything looks good from the outside for that to be true.

These guys aren't like Novak and Associated. "Hey look at our brushless motor due out soon!"......2 years later its out. The same goes for the TC3. Granted, Associated had to work out patent issues with 10th technology.

[jay272]

It's always entertaining to see how everybody is speculating whether or not a car is going to suck or be the shyt, ON NOTHING BUT PICTURES!! This car does look good, but that's it. I haven't driven one so I'll wait till some other fool buys one and shows it off at the track. I learned my lesson from buying the pro 3 and nitro ss. Even with the penguin chassis and other hop-ups, the car was still a pro 3. Thank god for e-bay.:)

[nomac]

outside of being effiecient and adjustable....durability and parts support is a great concern of mine. from the pictures i've seen, the car (LOOKS) to have all 4. see the pun.lol

i know it's been a few years but i still have the memory of beating sean (of associated) & steve rule (of racetech) on carpet with a pro1. and this was when the tc3 was the thing to have. with this new pro car, i hope to redeem my efforts from the roar nats up in cleveland.

that pro4 needs to get here NOW!! there's little tuning time between now and november.

Aw c'mon now, dont be hatin;)

You have to admit the pro 4 does LOOK like it'll be one helluva car when it comes out. I remember back a few years, when the first pictures and sneak peaks of the Xray T1 came out, everybody knew imediatly that it was going to be, as you say, the shyt. Given the pro 4 isn't nearly as refined (and hopefully as expensive:rolleyes: ) as the Xray was, but still. Lots of people are already bashing it because its shaft and looks like everything eles. Well by the same token, some of the fastest cars in the world are shaft and this one is no different in concept, so we can make an initial assuption that it will be a great performer. But in the end, to somewhat agree with you- track testing tells all.

[jay272]

hatin? I'd be a hypocrit if I said one bad thing about the pro 4!!

LOL

Yeah, I'd hate to say it but the pro 4 looks pretty damn decent. And people have the right to buy what ever they want. But isn't it just a little crazy to say how great a car is from a picture alone? Is this car so dramatically different from the yok SD, or those other shafters? I hate TC3's and this car is nothing like it.

But just look at all the people who bought those Tamiyas for close to $400 just because it looked cool (the evo and evoII). All the ones I talked to at the track were pissed.

All I'm saying is that it is way to soon for people to pass any judgement on a car from pics alone, in my opinion anyways.

ps-
s15racer, the Xray evo2 is the best thing on 4 wheels. It took me from C- mains to A-mains in 2 days (sunday racing). It hasn't broken a single part in the 8 months that I had it.

[Frank McKinney]

That chromed thing is a digital scale sold by HPI Japan. The number on the digital scale is the running weight in grams. ;)

AGREED 100% AGAIN...LOL that is exactly what i am planning on doing, it sounds all good and near perfect but so did the PRO 3! and look how it turned out! i guess i will just sit back and enjoy the show, and yes me too sold my PRO 3 on ebay for 110 dollars..lol

What is so funny about PRO3? I have one and I did win some races with it. It's up to a person who drive it not the car! ....thanks for ebay as well...;) ...not because of any problem that people are b!tching, but I already proved myself and the car that it's a winning potential so I move on to TAMIYA TBIII.:D

What can go wrong with PRO4?...Look like BARRACUDA and supposed to work like BARRACUDA as well.

sorry for my english.;)

[jay272]

Hey x-garage.

Can you honestly tell me that your pro 3 didn't have any excess slopp in the suspension and all kinds of wheel wobble? I had about 30 shims in the damn thing. Sure, you can win races with that P.O.S. but winning comes easier with a better car. That sloppy car just never felt consistant. On mine, I could even move the rear wheels in and out 3mm with the wheel nuts OVERTIGHTENED. Sometimes the drive shaft would just pop out of the outdrives because they were designed to short. HPI knew it and said,"oh well, the american *******s already bought it. Let them buy the correct driveshafts from an AFTERMARKET company with their own $$". What kinda crap is that from a company like HPI? I'm sure I'm not saying anything you haven't seen or heard of first hand.

I really did like the design of the pro 3 and I wish HPI would have used it again instead of making another shaft tourer. The "battery in the center" design made for some pretty sweet handling and left to right transitions. If the pro 3's parts where as precisely built like the x-rays, or the tamiya evo series, they would still be selling pro 3's. Have you ever heard of an rc company discontinuing a touring car 1-1/2 years BEFORE the release of its follow-up? Can you imagine Associated saying, out of the blue, we're not going to make anymore TC3's? Hell no!

Sure the pro 4 looks good, but you can't see the build quality or durability of the kit car from pics alone. I wish I had the money to buy a kit, test it out, and decide if I like it and keep/sell it. But I don't!!:( I'll wait until my idiot buddy impulsively buys one and check his out like I did with the X-ray evo2.

[X-garage]

Hey Jay 272!

Your problem with thw slopp in the suspension is something that I haven't heard. All the problem you are complaining make me curious what class of driving you're in?:confused: If you don't hit the wall you woun't break anything, but that would not happen in real life. Don't give all the credit to TC3. That car can't hit any thing as well. If you hit you break the arms! Look at the flex on that car. I'm sure there is no flex from side to side, but from front and back..OH MY! They are plastic and they flex!

There is no such a perfect car not even LOSI or TC3. You got to live with it. I don't care much to talk about PRO3 now, but it's a good car, but people judge the car before they even touch it.

I have been an owner of TAMIYA 414, TAMIYA TBIII, SCHUMACHER MISSION, NTC3, TC3 and PRO3...I like them all.

You can live without aftermarket parts, but chose wisely and it will benefit your car.

If Barry Baker doesn't drive TC3, Associated wouldn't be this big...that's all I can say.

:D

PRO4 is a good car.

[jay272]

There is one perfect car........the Xray evo 2!!;)

I owned a few TC3's and a xxx, and I'll take a pro3 over those anyday!

[X-garage]

PRO 4 took 2nd and third from JMRCA! 4 HPI in the top ten!

Where's the battery holder or brace? I'm not a big fan of taping anything to anything.

[RC-ZOMBIES]

Tape is better...it doesn't tweak the chassis.

[jay272]

Oh. Well I learn something new everyday. I had no Idea that battery hold-downs tweaked a chassis.

depend on the car and how stiff the chassis is...
on my new 'Cuda.. I used the Hold-downs and tweaked the chassis really bad... after using tape... all gone.. :)

don't know on the Pro4 yet... we'll see after I get one. :D

It's safe to say... it will be in production very soon and on the store shelves..hopefully by Christmas..

[X-garage]

I'm ready to spend!:D

[jay272]

By christmas? Why so long away? They've been testing that car for a while now right? Will there be any changes to the Pro 4 before production?

darn! that sounds too late. if i can't have it by cleveland, then i won't buy it! see ya around 10/02/03.

So I got my 2004 Tower Hobbies catalog in the mail yesterday and guess what I found....

HPI RS4 Pro 4-
yadda yadda yadda
see www.towerhobbies.com for pricing info

So I go to tower and guess what? Its not even listed yet:mad: What the heck is going on? Is it on sale yet or not? You'd think it would be, they had the R40 out faster than this:rolleyes:

RC-Zombies- whats the latest? is it out yet or do we really have to wait until Christmas?

And StevePond- when might we be seeing a test of the pro 4 in RCCA?

I wouldn't go out and buy one right away....wait a few months to get all the bugs out of the first production kits.

A friend has said...after test driving it...it has alot of torque steer... and it could use a thicker chassis to help eliminate that.

[S15Racer]

Yes, you've given that advice before and I plan on taking it, but I was just confused about the tower thing:)

BTW- you friend, is his name by any chance Atsushi?

Pro3...had 2.. sold them earlier this year.
TBIII... too many problems with the spur gear.:(
SD... sold it after 1 race...
Xray Evo2... sold it after 1 race.. I would have kept it but 1 too many cars gathering dust.. it was great car. very fast.. very tunable.
Currently racing the R2 WEB special Edition.. the Orange car #28 of only 100 made. The car accelerates and corners fast... this car is a keeper.
Cost a ton of money but worth every cent. THe std. R2 are great too.
Future...
Pro4...I'll wait and see.... only if a Hara Edition comes out. A friend test drove the proto... said had too much torque steer...
Xray Shaft car... coming soon.. Xray quality and craftsmanship. Most probably the ultimate touring sedan when it get release in a year or two.

[X-garage]

I agree with you on TBIII. I'm so ready to sell mine as soon as PRO4 get released and TBIII will be a history.

R2 is the car I have been looking forrward to get, but how easy you can get parts?

R2 is the car I have been looking forrward to get, but how easy you can get parts?

I get parts from SpeedTech, from RainbowTen in Japan, or RcModel in HK. Takes less than 5 days for parts to get to me from overseas. Car is very durable. Check out the R2 and Alex racing forum at http://www.rctech.net/forum/index.php

[nomac]

het...we got some action here! still no word on availability huh? oh well....be back in a couple 'o days.

[nomac]

looks like the pro4 has lost a lot of intrest here. anywhere else on the net that has a more lively forum?

[Nexus]

nomac.

i think the Pro4 forums will be slow until the car is officially released and nonsponsored drivers start to race them.


i for one have been following the threads and not posting much. i'm waiting for it to be released and make sure it doesn't have any major flaws or shortcomings.

the B4/T4 were released and worked great with minor things like the steering rack tolerances were a bit off.

can't wait...Pro4!

[Kenny T]

Guess who has pictures of the JMRCA meet and lots of pics of the pro4, one guy had lots of purple alu on his, probably the new hara ed (if there is one).

[rcguy2477]

On the Hpi site, it said the car would be released in fall of 2003. Everyone is saying it will be released around december, which isnt fall. Does anyone know when it really will be realeased?

[S15Racer]

Whoa, alert the athorities!- we have activity in the pro 4 forum!!!

:D

Just saw the test of the R40 in RCCA, so the test of the pro 4 is probably only a couple of issues away.

Zombies- is there any word on that torque steer problem you mentioned?

[nomac]

i was hoping it would be released by the indoor champs, but from the looks of it........it may be on the hobbyshop shelves in time for the snowbirbs.

but there is a new Alex Cuda R3 coming out at the same time as the Pro4. :D that I may get instead... ;)

cuda r3 :P

nahhhh hold out for the Pro 4.

I'm hoping with HPI's big presence here in the states the parts, prices and availibility won't be a big issue.

i would purchase a Tamiya Evo3 but parts can get pretty expensive compared to the TC3/XXXS cars.

[Nexus]

somebody....anybody have any new pics or news?

:confused:

[Kenny T]

I have pics, good detailed, close up pics. I just have no way of showing you guys, my teacher at school won't let me scan them and I don't have a scanner. If you have any questions about the car ask me, I think I can answer them by looking at the pics.

from what i've read 1 or 2 guys out west have been racing/testing the Pro4 for awhile now. i don't remember their names but they were HPI employees.

here is a new pic from HPI Japan...

[rcguy2477]

Are the arms and bulkheads made of plastic or graphite. I thought originally that they were going to be made out of plastic, but in those pics, it surely looks like they are made out of graphite.

[S15Racer]

Carbon Graphite all the way dude, its always been said to have HPI's carbon grphite material used on everything that would otherwise be plastic.

What I'd like to know is what the deal is with the CVD's are they purple or silver? Its gone back and forth with every new set of pic that come out. Not that it really matters much, but its still interesting:D

:Stupid question edited out::rolleyes:

[Kenny T]

The CVD's in my pics are steel but one guy was running aluminium. Also the diff hubs in my pics were delrin they appear to be plastic or steel.

The pro4 in my pics didn't look like it had so much carbon graphite.

:confused:

[RC-ZOMBIES]

I read on another Forum that Thad Garder is testing and racing one... he TQ'd at Socal raceway just recently.

:confused:

the diffs in your pics are also made of carbon graphite...the same material they they have used on the Pro2 and 3. you can tell by the purple diff ring on the outdrives... Steel diffs won't need those rings.

[Kenny T]

Now that I am home (not school), I can see the carbon graphite in my pics(very hard to spot when not enough light).

RC-ZOMBIES, Look at the front outdrives, they are steel, so I was kinda right but I know that the rear diff outdrives are delrin (in my pics).

Kenny T..

Most probably the front is a front one-way diff.

[S15Racer]

Thats what was spec'd in the original designs...

[Kenny T]

As much as I don't like this car I just might have to get one. It looks so good to not get. :D

I have a choice of either this or a NMT2. :)

Can't decide. :(

Interesting top deck there.

[S15Racer]

That pic ie probably one of the original prototypes that were made out of random parts and pieces from lots of different TC's. That deck and chassis was probably custom made.

Hey, in the interest of keeping this thread alive, anyone want to start a pool for who can guess the closest to the acual release date? I dont think theres any way that a prize could be involved, but want to take guesses just for fun?

[Kenny T]

December 21st is my guess. :D

[xtreme]

Yeah, December 21st, 2007 :D

[RC-ZOMBIES]

Japan release date... Dec.15th. - 8am.

[rcguy2477]

I am guessing around january 15, because there arnt any preorders out yet. Usually there are preorders out at least 1 month before it comes out.

looks like the Pro4 is getting closer to hitting the shelves....

from this event overseas it seems some guys are already racing the Pro4....

here are some pics from HPI Japan.

i can't read japanse kanji but it looks like they used the Pro4 at this HPI Challenge.

yes...the team guys are already racing the production versions.
should hit the shelves very soon(in Japan)... but may be a month later for the US to get it after Japan's release...what else is new.:confused:

[Kenny T]

Go here (http://babelfish.altavista.com/) and put the link in and translate it, I can read Japanese but only some kanji.

I don't know what to get, NMT2, Pro4 or Pro3. The Pro3's are going dirt cheap in Japan, a Hara edition was going for 14,000 yen. :eek: :eek: :eek:

[nomac]

how much is that US?

[jay272]

I think it's a very bad Idea to advertise a car, and have racers running pre-production models of it for over a year before the car is actually available. I'm sure that I'm not the only guy who got tired of not seeing an ACTUAL release date, and bought a different car instead of waiting. Or am I?


6 Months later, still no release date? What the hell? :confused:

[Kenny T]

about by guess $US120

[rcguy2477]

i have been seeing some pro3's going for only 90$. Instead of waiting for the pro 4, i just bought a tc3 and a new graphite chassis.

[nomac]

thanks kenny

[RC-ZOMBIES]

Latest news: The Pro4 has been released! Finally!!!!....
on HPI Japan new release page.

http://www.hpiracing.co.jp/contents/lineup/newoption/0312.html

Hopefully the US will have it by end of Dec.

[tperkins]

You can pre-order it at www.speedtechrc.com Price is an estimate, but they are usually good on the price that it will be. Hope it goes down some, though.

[S15Racer]

Holy crap i hope the price goes down, gees:eek: If its that expensive on tower I might just skip it and do some stuff to my pro 3, or get a LSD for my car:rolleyes:

[rcguy2477]

290$ isnt that much. How much were you expecting it to be? Compared to other high end tc, the pro 4 is still cheap. Expect the prices to lower after a month or two, but i have a feeling that 290 will be around the standard price.

[Kenny T]

Woah, the price is too steep for me, I'll just get a NMT2 in kit form if HPI ever make one and spend just a little on the Pro3.

[S15Racer]

Well I wouldnt expect it from features alone to pull $290+ Like we said before in this thread, its very similar to the STR-4 Pro, which retails for like ~$200. I guess were just paying for all of HPI's R&D on the new chassis, instead of the acually cost of production. I have a feeling it'll be cheaper elsewhere though.

cheeper? hmm... $239.00 from Champ HObbies in Japan. but after you pay shipping and services charges...about the same from Speedtech.

[S15Racer]

Now thats more like what i was expecting. I doubt I'll get one though, for the next couple of months anyway. Too many other things to buy. Stuff for the car (1:1) might have a girlfriend in the next few days... stuff like that:D Maybe after I get a stable income I can buy one, and by then the price will have prolly come down anyway right

[RC-ZOMBIES]

For those who can't wait...
RcModel in HK will have the new car instock on Dec.19.
3-5 delivery is aviable..just in time for X'mas.
$349.99 + ext. $25-40 shipping.

http://shopping.rcmodel.com.hk/prod...roducts_id=3554

the US should have the kits soon after.

[RC-ZOMBIES]

[tunerjetta29]

Its not very promising that HPI goes on x-mas break more or less on the 19th. What do you think the chances are they will get any Pro4 kits sent out by then. Id say 0%........guess my pre-order will remain into January........i still cant wait though.

[microrcdude]

why is it $400 on tower?? It's probably worth it, though

[RC-ZOMBIES]

Originally posted by microrcdude

That's retail price...and not worth....cheaper at Speedtech RC for $290.00 which may be the estimated street price. Tower woun't even come close to Speedtech prices....

[tunerjetta29]

Yeah i have it pre-ordered at Speedtech. Their prices are always awesome and they have great customer service.

[S15Racer]

methinks I'll be waiting for a few months for the prices to go down. -Unless I win the lottery, in which case I'll buy ever single person in this thread a new pro 4:D

Thanks for the SpeedTech info, guys! I got to get in line for a Pro4.

you guys prolly shouldnt get your hopes up, I never play the lottery. But should I, by some alignment of the planets apocaliptic (sp?) chance, play and win, I'll keep my end of the bargain:D

[lhistand]

It looks like the Pro4 comes with a one-way diff up front. Anyone know if the front and rear diffs are interchangable, and if we can put a standard rear diff up front? :confused:

Man.......im bored......>RELEASE THE FRIGGIN CAR ALREADY :)!!!!

[RC-ZOMBIES]

The cars been released..

For those who have there kits already.. :D

HPI R&D cafe release:

Yesterday, as for Pro4 which was shipped you think that quickly already it has lined up into the store. Then, you try to introduce little secret when the assembling Pro4 to everyone.

Please prepare the tap of M3.
Pro4 has used the carbon mixture resin for the various parts. As for this carbon mixture resin there is a feature which rigidity calls high and light weight very. Because of that it is very hard the occasion where the screw is screwed in, operating efficiency becomes bad. Very it becomes easy to work by the fact that the tap of M3 is cut beforehand then. The point is not to cut the length all tap of the screw here. The length which cuts the tap when it makes 2/3 of length of the screw, screwing in the screw, becomes lastly hard and becomes also locking.

Pivot as for installation of mount prudently.
With Pro4 the suspension shaft is locked at pivot block the chassis. The occasion where this pivot block is installed in the chassis, paying attention to the movement of the suspension arm, please install. When the screw stopping pivot block securely, please verify that the left and right both suspension arm moves smoothly. When the suspension arm of one side does not move smoothly, pivot block has been installed slantedly. Loosening the screw of one time pivot block slightly, in order for pivot block not to tilt on left and right, while locking securely by the hand, it tightens the screw and densely is please be. If and it reaches the point where both suspension arm left and right moves smoothly, it is OK. As for this part when travelling when big crash is done even, please try checking.

The present place is to here.
As for the next time, it is the schedule which introduces Tips of method of assembling the gear box.

Everyone, without being hasty, don't you think? please assemble and read the instruction manual well and assemble.

R&D FUJIWARA

[S15Racer]

OK, now i have a headache.

What was that, something about the carbon graphite parts stripping the M3 machine screws or something like that? And something about the positioning of the pivot blocks? I hate reading stuff thats been translated from other languages...

[Downforce]

Had to find my secret decoder ring to read that.

I think they're saying to tap the hole 2/3rds the way in. This would alow you to start the screw and would lock it in position.

As for the pivot blocks. Sounds like they move around under hard crashes. Just like my EVO III.

We'll if they said December and now January i guess well still be waiting in February..........thats too bad....i want my car now :(

[tunerjetta29]

I canceled my order through speedtecdhrc and i decided to order one through RCMODEL cause i couldnt wait another month and a half. So hopefully by New Years ill have my Pro 4!!! (They ship on the 22nd)

[jay272]

Why not just wait for the Pro 4 to come to the US? It's not like anyone is going die from waiting a couple weeks for an RC car to be released.:confused:

[SpeedDesignz]

all this delay is getting to be bullshite.

it's really begining to turn me off from HPI.

maybe I should just buy the yokomo SD it's pretty much an identical car.

[tunerjetta29]

Well i wont wait because to me id rather pay an extra $30 to get an extra month of track time in than sitting in front of my computer.

[lhistand]

I counldn't wait for the the Pro4, so I bought a Yokomo MR-4TC SD. This thing is awesome! The quality of components and design are outstanding, and that SSG chassis is something to behold! All ball bearing steering, diffs come out in a minute, beautiful shaft drive system, lots of blue anodized stock parts, stainless steering and suspension turnbuckles, etc. I can't believe the PRO4 is going to match this. The Pro4 will cost more, and parts will be hard to come by. The Yokomo MR-4TC sd is a winner!, and it's available NOW!

The pro 4 is cheaper than the mr-4tc sd. The mr-4tc sd costs around 300 were as you can get the pro 4 for around 250. And hpi parts are a lot easier to come by than yokomo parts. My friend has one and he always complains that they dont have parts in stock and that some times you cant even get them from yokomo because they arnt in stock.

[SpeedDesignz]

http://64.70.208.72/speedtechrc/95.html


269.00 for the Yoke and they usually have all parts in stock and cheaper than anywhere else. plus now they just released a whole slew of graphite parts.

There estimating the hpi at :
http://64.70.208.72/speedtechrc/298.html

289.00


So the Yoke will probably be cheaper,sexier,and available now.

[tunerjetta29]

Well no offense to yokomo lovers but i personally find the Pro 4 much more attractive looking. But thats personal opinion. As far as pricing thats an estimation there is no telling whether or not that will be the final price. Lastly look at the price of HPI replacement parts. Most the time a full tree of replacement parts is just a couple bucks.......and almost every hobby shop has all of them in stock. Can't say the same about yokomo.

[lhistand]

I'm a big HPI fan, and thought that I could always get the parts I needed. But I've been waiting for 3 months! for upper decks for RS4 Rallys. If I don't get them soon I'm going to buy some graphite plate and make them myself! It shouldn't take them that long to organize the supply of these parts.

I'll likely have a Pro4 six months from now, but I'm going to have a lot of fun with my new Yoke!

That pro 4 is hot! But, just wondering here, what does that kit do that the stock pro 4 cant? Just make it look better?

[tunerjetta29]

Well i agree with the lack of HPI parts in only one aspect......discontinued kits. Such as the RS4 rally....
Other than that part availibility is great.

[microrcdude]

the rs4 rally is not discontinued

[SpeedDesignz]

my LHS/raceway is cutting down on HPI parts.

There simply is no need. He sells some savage's and keeps parts for that in stock, and micro stuff of course. But there hasn't been an HPI touring car on our track in years.

[tunerjetta29]

My mistake.....i could have sworn the rally was discontinued, since it is based on the original RS4 platform... But HPI's site says it isnt.

[RC-ZOMBIES]

anybody get one for christmas...

Looks fragile and kinda ugly looking to me:D

[S15Racer]

Well, the front and rear braces are kinda ugly, but I like the side brace things. Never seen anything like that on a car before. At first I thought the kit was kind of a conversion to a bath tub style chassis, which would keep it stiff without the need for an upper deck. But in the second pic it has an upperdeck, so idk. I still think it looks cool, lol:D

[RC-ZOMBIES]

I told myself I would wait til the Hara Edition Pro4 came out...but I could not resist... HPI outdid themselves this time... In the process of assembling the car now...pics at:

[HPI-Fan-4-Ever]

Hey guys,

I wanted to get into electric touring, and the Pro 4 looks pretty sweet, but I have a few questions...

how fast do you think one can go with about an 11 or 10 turn motor?

Also, I got a B4 buggy and some Epic unassembled cells, but I took the cells back so I wouldn't have to worry about building them and perhaps screwing them up....but is it really hard to assemble your own 6-cell packs like needed for the Pro 4? If so, I would prolly let a friend of mine assemble them, he's like the electric master....

Also, what exactly is carpet racing? (don't tell me its racing on carpet, i'm not that dumb....i hope:confused: )

[Frank McKinney]

Carpet racing is, indeed, racing on carpet.

[HPI-Fan-4-Ever]

yes i was aware of the fact that carpet racing is.....believe it or not, racing on carpet, i guess i worded it wrong, i meant that, is it carpet like you find in your living room, what kinda tires are used...etc...... .......it seems a lot different from pavement racing (which is racing on pavement!! sorry, that time i couldn't resist) its just that i read about hara and others winning big electric carpet-track championships (hara did win, right?) and i thought, why not just run on pavement like every other on-road car does.....i was just curious is all......

besides, if i can get into carpet-racing, i can have an excuse to run my car in the living room!!!! :D

[SpeedDesignz]

The carpet is not like the kind in your house.

it's ozite carpet very low and fine, alot of traction. and you can race all year long.

this is the track we race at avery Friday :

Shipping Feb 11'th or so.

I have one on order - first one to come into Trackside.

I've been out of touch for awhile, and still lovin' my Yokomo. And SpeedTech has been absolutely great supplying whatever parts I need. Now I see the Pro4 is finally here, and available on Ebay!
But I'm happy -- I'll buy a Pro4 the first time one beats me in a fair race. And that's not likely toi happen soon!!:)

[C0NTENDER]

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


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

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

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

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

My first movie of the pro 4!!!

"The incident with 3PK"
http://www.******.net/view_single.php?medid=26586

[S15Racer]

Warning warning, im about to post a reply in the pro 4 thread. Seeing as how no one ever does this anymore this may seem alarming, but I assure you there is absolutely nothing to worry about... that is all.

I got the new RCCA yesterday and read the review of the pro 4. I was thinking for a while of putting rc on the back burner and even about selling all my stuff and getting out of the hobby. I dont think thats going to be the case now. I'm thinking I'll buy the pro 4 later this summer after I've saved up a little $$$ (my first summer with a real job) and start racing again. Oddly enough, I also read Extreme RC cars' review of the pro 4, and they kind of contradicted some of what RCCA said. For instance, RCCA praised the quality of the drivetrain componants and said that they didnt require any hand fitting or modification to work perfectly. XRC said that the diffs would require half an hours worth of shiming work to get them to operate properly. How many of you guys have the car now and what are your impressions of it? Any suggestions? Lets see if we cant get this thread back up and running again.

btw NMT, the vid doesnt work hehe

[Kenny T]

Don't get out of RC, you're the other guy with a Pro3 who's regularly on the boards. :)

With the diffs needing shims, doesn't it have ball diffs?

[RC-ZOMBIES]

S15racer...

didn't I say I won't buy a Pro4 until the Hara edition came out...hehehhe I liad..
This is probably the best car I've ever drive...very fast out of the box. as far as shimming the diffs... each kit will very...just like other kits... if you follow the instructions properly... 8 times out of 10 it will run smoothely! after the break in period then you'll know if it additional or less shims... buy one...you will not regret it... ok... back to the RC-tech Pro4 thread... :D

[drift_kid0]

Im getting my pro 4 this friday...woo hoo!!! my friends are gonna be so jealous but i might have some competition with my teammate who has a fully hopped pro 3 (well almost fully hopped-up)...but once i drop in my motor and some good gear setting ill be blowing by him... MUHAHAHAHAHA

[S15Racer]

Kenny T: dont worry, they were just thoughts, Im not getting out of the hobby just yet. Its just that the pro 3 has been giving me fits lately so you know how that goes. It still glitches something terrible, thinkin maybe its the servo now, who knows :rolleyes: I'll just have to see how the pro 4 turns out and if its still practical for me to race. Hopefully with a steady income it'll be easier.

RC Zombies: Good to hear from you man, I was afraid you were long gone by now. So you broke down and bought the pro 4 huh? Cant say im surprised... :D My question is... how much more can they add to this car to even make a Hara edition worthwhile? Its got pretty much everything... ti turnbuckles, carbide diff balls, front one way, graphite/aluminum everything... everything any racer could want.

I really hope that with my job this summer and all I can race on a regular basis, I havent been to the track in months :o mainly because its an hour away and $12 per car :rolleyes:

Hey Zombies, one more thing, what kind of track do you run on during the summer? And whats your setup? that would really help me get back in the saddle a lot quicker, thanks.

oh, one more thing (last one I promise :D ) could you provide a link to the RC tech forum/ pro 4 thread? thanks :)

[S15Racer]
