so which one do you like better...is the wolfpack car worth doing?....or should I just biuld another Super with HPI parts...also,how do you like the 300 mm wheelbase...my current car is a BMW...dying to build a toyata GT...

RandyT · #27 11-03-2002, 12:06 PM

Fezzy:

Go to www.wolfpackradicals.com and look under Super HPI, then Super Parts. It includes the chassis, top plate, mounts, flywheel, etc.. You will need to purchase an additional mid block and I believe a different belt for the side belt. I would suggest getting a better Y-brace also.

I had alot of trouble with my 8 Port, but its finally running now. I'm sure after it breaks in alittle longer and I tweak the tuning it will be fine. The motor has alot of pull. I'm running 13/20 and 44/37 and it has no problem handling these gears.

Well I can't say yet, I'm more familar with my reg super with the way it handles and my current set up is also with the bmw body b/c I'm normally running on tight tracks. So could could be why I had a hard time with the wolfpack using 300mm on the same track. I'll do more testing at the beginning of next season. Is it worth it, well if you already have one super, and you just want to build something out of spare parts and you have the money and don't mind spending the money on a project car, it's worth it. Myself, I have debated saling mine time and time again, only b/c I'm not sure if I have a real need for two supers, but I will address that concerns after I get rid of the purple alum one first. If I keep it, it will probably only be used for drag racing, but if I can get it to handle like the super that I race with, then I will probable use it for racing except for the hpi challenge.

Heres more recent pix of my Super. I added a WP bigblock conversion and a JP mod TX15 engine. Im running 17/20 gearing aswell. The car has a lot of low end but I needs to be tuned a lot. I only ran it a few time and haven't been able to tune the engine correctly.

I am actually thinking of saling it cuz I really don't have much time to play with it any more.

OK, I am new for the HPI Super Nitro but definitely not new for Nitro racing (Serpent Impulse, Impact and currently NTC3)....however, this HPI super nitro does give me quite a lot of problem, but I am sure you guys can help....

I have a brand new Nova Rossi RS-12 T5 planning to drop onto the Super Nitro, and my Super Nitro came with the HPI 2-speed gear box already.....my quesiton is, how can I install SG cranck engine (like any Nova Rossi engine RS-12, MT-12, MR-12....etc) onto the SNRS4 that works with the HPI 2-speed...?

From the post above, I saw him got his JP installed on the SN....what kind of a flywheel and 2-speed clutch that he is using..? Or can anyone tell me what and how to get that works...?

Someone from the LHS told me I have to use the HPI clutch and machine the hole (larger) and re-taper the end to make that work....but is there any aftermarket flywheel that I can use..?

Thanks for advance....

Yeah the SG shaft was a problem for me, but Wolfgang gave me some good knowledge I'll pass on.

1) Flywheel: I use is a wolfpack radicials, but you can use others.

2) Length: You need an ofna clutch nut kit to make the sg shaft long enough. It cost less then $10 and can be found at towerhobbies or your LHS.

3) Clutch: I had the HPI Racing clutch but it wouldn't fit around the clutch nut kit. I dremeled it to make the hole bigger, but decided against modifying the clutch. So i just bought a Ofna 3 shoe clutch and used 2 of the shoes. A mugen clutch will work too.

Hope that helped!

Thanks....yeah, my LHS also susgested me to use the Wolfpack .15-.21 conversion kits, it came with a purple flywheel and adjustable engine mount (I think you are using that too)....costed like $65.00, is that the kits that you are talking about...? The reason I am not getting that is because that flywheel is so small and it doesn't have the OFFSET(standoff) like the HPI flywheel does.....in that way, I really don't know how's that work with .12 engine (since .15 and .21 are bigger and longer, that might work)....

Can you tell me the wolfpack flywheel parts #...?

I do have a MIP clutch and HPI clutch housing, do you thing that will work...?

One more thing, can anyone post some closeup pictures of the 2-speed gear box area so I can take a look...? I know I am asked a lot, but someone might took some pictures like that before...

Thanks again.....

JohnLeMVP · #33 11-10-2002, 10:35 PM

I have a Tx15 which is a big block motor so the wolfpack parts work fine.

Your engine is small block so just get a regular flywheel.

The only thing you need for the SG shaft is an ofna clutch nut kit and maybe a clutch.

Rookie Solara · #34 11-11-2002, 10:03 AM

But the problem is exactly the flywheel, HPI flywheel won't work unless I have to custom make one....the hole is not big enough to pass thru the thread and the tapered end is too big for the Nova Rossi golden nut......

Any other option....?

RandyT · #35 11-11-2002, 11:58 AM

Is that .12 with a SG shaft going to work~? When I was looking for a new motor we placed a Sirio .12 on the car and the SG shaft was really short and even with the Ofna Kit the clutch bell wouldn't reach the two speed.

I think there was a thread on the HPI Super Nitro Forum on how it could be done, but you will have to wait till the site is back up.

Good luck

Yeah, I know the exact problem, the SG crank is still too short to reach the 2-speed.......any other idea?

The site isn't going back up

RandyT · #38 11-12-2002, 03:14 PM

Really they aren't going to bring back the forum on HPI~? Bummer
In regards to the SG Crank sorry can't help you there, I think your just going to have to purchase .12 with a standard crank, or go for a BB15 or .21.

Rookie Solara · #39 11-12-2002, 05:42 PM

HPI forum will be back, but it will not be FORUM afterall, more likely those YOU ASK, THEY ANSWER kinda style.......which is another BIG MISTAKE....oh, on top of that, only HPI related only, no more Serpent, NTC3, Reflex whatsoever.....Big Big mistake.

Anyhow, believe it or not, I emailed Wolfpack and see what is they thought about .12 SG engine on Super Nitro......they emailed back to me today with a 6 paragraphs message

and even offered me a FREE kits to me, the take is I have to give them a detail reports no matter it works or not.....why it work, and why not.......

I think I have nothing to lose here..........as much as I HATE to sell my brand new Nova Rossi RS-12 T5 (hard to find now).......and I will try my best to get that sucker installed on the Super Nitro.

JohnLeMVP · #40 11-12-2002, 08:14 PM

Yeah wolfgang is a good guy. If anything goes wrong with one of his products, he'll usually replace them if you tell him what went wrong and why.

Rookie Solara · #41 11-12-2002, 09:07 PM

That is the attitude for a sucessfull business.......ppl like Wolfgang should receive all the respect from all the RC racer.....

Browny · #42 11-16-2002, 12:09 AM

I'm impressed with this wolfpack conversion kit. I live in Australia and RC can be pretty expensive. Can anyone tell me how much a Super RS4 sells for in the US? (in $US).

Also I've look at the wolfpack web site but there isn't alot of info there. Do you buy his products thru hobby shops or from him direct?

Do you guys race competively? Is there a class that accomodates these larger cars?

Finally, (please don't hate me), with the .21 engines what sort of speeds are you reaching?

Some great pics on this site too

Thanks in advance.

Super Nitro should be like $250 US with the POS engine.....

Wolfpack products can be purchased via...

http://www.brucknerhobbies.com/

Or you can contact Mr. Wolfgang himself, super super NICE owner/Tech guy to deal with.............wish he can do more alum. stuff for more car (like NTC3)

To be honest, in Asia (closer to you from Australia) Super 10 and Super Nitro are 100% GONE.......no one race there, in USA, beside HPI challenge, ppl usually race Super Nitro just for fun.....but here in Chicago, we do have enough Super Nitro to form a class, so we are a few that still have Super Nitro class racing along with those typicla "TOURING CARS".........

Engine limits to .12 and .15 engine, turbo or non-turbo, don't matter, no modification limits, no GAS-TANK limit cause we all using 125cc Kyosho buggy tank........to tires limit - foams are $32 a set of 4, last like a season long.....so no one using rubber anymore......basicly - NO LIMIT, and the best part is, we will MIX with Serpent IMPACT class and race together.......and don't let the Super Nitro fool you, IMPACT has no advantage over Super Nitro beside the big block .15 engine....at one point, I too own a IMPACT and raced with the Chicago HPI challenge Super Nitro champion.....and I learned my lesson well. So if you don't have enough Super Nitro, let the IMPACT ppl race with you or join the IMPACT ppl.........if your Super Nitro tunned well enough (and with a good enough engine like MR-12, RB, JP....etc) those IMPACT are not even that fast afterall....(if you recall the recent national races, most TC ran more laps then IMPACT and 1/8th class).

Last.....with 21 TURBO JP engine, one time I saw the POLICE speed gun clocked 80 mph, and I am sure some others can do even more......

Browny · #44 11-19-2002, 05:01 AM

Thanks for the detailed reply. I haven't seen any Super nitros racing in OZ. I would love to see them do so as I would like a bigger scale car. Somewhere between the 1/10 and 1/5 scale. Ah well I'll stick with the 1/10 for now.

All the best with your cars.

Rookie Solara · #45 11-20-2002, 11:52 AM

OK......with the strong support from Mr. Wolfgang (owner of Wolfpack Radical).....the small block .12 SG crank engine conversion is a complete success, and here are some instruction (save this file Robert Carlin)

This picture showing the SG crank engine problem, engine sitting too far apart from the 2-speed spur gears and the SG crank is not long enough for the bell to reach the spur gears. I used 10 OFNA washer, Assoicate Pull-start flywheel, Serpent clutch nut and shoes, and HPI gear bell. 2nd picture......I pushed the engine toward the spur gears direction......it reach the spurs, but the engine mount doesn't align with the HPI chassis engine holes underneath, adjustable engine mount required.

With Mr. Wolfgang's support, these are the parts that I need to do the conversion. Vented flywheel with special cullet, adjustable engine mounts (6 position with free sliding adjustment base)......the 2-speed gearbox clutch is something he strongly recommand me to change over the HPI single blade design.

Wolfpack radical package installed........along with the OFNA crank extension kits ($7.00), I installed 2 OFNA washers before I mounted the collet to gain some extra length of the crank. From this picture, you can see I aligned the engine mounting holes with the HPI OEM opening underneath, and still, the gears are still SHORT from reaching the spur gears....next, adjustable engine mount.

Adjustable engine mount installed.......now, I can slide the engine by 4mm and still have a complete lock tight situatin of the engine....and the most important part is - I have the distance in able to reach the spurs with the gear bell......operation completed.

The Wolfpack Radical 2 shoes 2-speed clutch installed (they are Associated parts) but somehow Wolfgang can get that work on HPI.......go figure.

If you have question, please let me know........because I am an expert on HPI now (yes......Wolfgang asked me several times why I downgrade myself from Serpent to HPI........? I think this is the fun part about downgrading - CHALLENGE)

What would you guys recommend for a new nitro owner's first hop-up engine? I don't want to spend much more than $150, and I don't need a pullstarter. Also, what's a good header/exhaust to use? (My SRS4 is mostly stock).

Mika · #47 12-12-2002, 02:16 AM

I don't know really about HPI engines, so I cannot say if these can be considered as hop-ups, but one good, quite powerful and realiable (=easy) engine is the O.S. 15 CV-Hyper http://www2.towerhobbies.com/cgi-bin...?&I=LXPV46&P=7. For more power although not so easy one is the O.S. 15 CV-R http://www2.towerhobbies.com/cgi-bin...?&I=LXALL4&P=7 for around $150. There's many shaft options though, so be careful to choose the right one for your car. I've used the CV Hyper for my Kyosho SuperTen along with Kyosho special tuned pipe and it's fast enough for me. For the coming summer I've got the 15 RX http://www2.towerhobbies.com/cgi-bin...?&I=LXBZ31&P=7 $159 which could be an option to you as well, but it may require more other parts to be installed on HPI (it comes only with the SG shaft).

I have 2 engines for you (both less then $100)......since you don't need anything powerfull untill you are in control on your SNRS4.

OS .12 CVR, this engine was on my NTC3, took 1st place all the time and only raced 3 times, 95% new, professionally broken in, and compression is like 95% life left......$80. because it is OS, after the first dialed in, you should not need to touch those needle again......

Another one is BRAND NEW, never use, HPI .12 SS (Black) engine, slide carb, standard shaft........$90

Both engine have similar HP and performance....let me know.

Think TWICE before you headed down to SG crank engine, HPI required more then a WORLD to convert the SG crank engine onto any HPI cars.

If you want to know more, see my post above.........it will costs you.

BlueMaxx · #50 12-12-2002, 02:33 PM

Would using an HPI .12SC make any sense as far as performance/replacement parts go? Sleeve and piston sets are cheaper than for any other engine I've seen, plus it's rated to just over 1hp. Would this be a good match for my SN?

And one more thing... I keep hearing about guys using Kyosho Inferno 7.5 tanks on their SN's. Is this a pretty much direct fit, or does it require some modification?
