Dropkicked, dang what engine is that, I'm guessing it a competition .12 like an RB or somethign...

Forgot to ask before too, what is the stock 2 speed gearing on this car? Should I gear it down for a more powerful engine? Anything else I should know?

Later

OK, here's the pics of the HPI 2-speed clutchbell on the Traxxas 2.5.

in order:

1. large washer from OFNA 10099

2. inside clutch bell:
HPI B070 bushing
Ball Bearing x3
HPI B070 bushing

3. large washer from OFNA 10099

4. small washer form OFNA 10099

5. 6.8mm spacer from OFNA 10099

6. 10mm hex screw from OFNA 10099

The reason for the 3 ball bearings is I accidentally crushed the hpi bearing. These are alot smoother anyway.

talon51,

the gearing for the super 2-speed is 13/44 16/41. The 2.5 pushes these gears with no problems at all. I am sure I could push the 18/37 easily.

Hope someone finds this useful,

Drop

Dropkicked;

Thanks for the pics. Looks like the short 1-spd pilot shaft would work perfect with the Nitro-3 clutchbell. Just leave out the Ofna spacer.

Thanks, Popsracer

Going to try and run my Super this weekend with some Foams at a new Track that has Freshly layed Asphalt. Hopefully the traction will be good enough.

talon51 · #**329** 03-20-2003, 12:05 PM

Thanks for the info...hopefully I can afford to put the Nitro 3 2spd clutchbell on there pretty soon, I'll let ya know how it turns out...anyway...
So many engine choices...I'm considering getting a Fantom .12 or .15, definitely slide carb, but I'm not sure as to whether its gonna be pullstart or not, I'm also considering getting a Sirio .12 Roar legal or outlaw, but I'm not sure yet. It might all come down to the money I can put up for the engine because I'm an umemployed college student. The Fantoms are pretty inexpensive, and make really good power, the Sirios are also amazingly cheap for engines with power in the SICK category, I also need a pipe for mine, probably and inline, so that kinda limits me to rear exhaust, unless I get a regular high performance pipe.... any recommendations or comments?

popsracer · #**330** 03-20-2003, 03:00 PM

The Novarossi (brand) EFRA Pipes make excellent power with a very wide powerband, but are expensive at $40-$45 usd.
I'm currently using an O-Donnell Pipe, very long diverging cone softens bottom end power with an increace in top end power. Perfect for low traction surfaces.

I also think that I'm going back to the HPI Racing Clutch shoes. The Kyosho clutch in my Car, hits too hard for the Low Traction conditions that I'm stuck racing on these days.

The Fantom .15 works really well in my Super so far, even with the Larger P/S flywheel installed.

i am sorry for chaging the subject but i have an anouncment to make. the msn group hpisuper nitros is now open and any one who has a super can join, there is a chat room and place to put pics of your super well see yah there

the site is http://groups.msn.com/hpisupernitros

ntn324 · #**332** 03-21-2003, 01:10 AM

and for another off topic subject, it looks like HPI is planning to release an electric Super RS4, hopefully this will generate more interest in the Super class and thus more options overall for the super class
also, it looks like HPI finally decided to release a two shoe type two speed transmission clutch, its looks like its meant for their shaft cars though, maybe not, im not really sure, its not specifically stated i think
for more info, just go to HPI racing's Japan site
http://www.hpiracing.co.jp/

popsracer · #**333** 03-21-2003, 01:56 AM

I kinda doubt HPI will sent it over from Japan. The Super class is almost dead in the USA now. But one never knows. I have a Friend that works for HPI USA and I'll ask Him if he knows anything about it. (he wont talk about the R40) The shoe type clutch is currently being tested in the USA at local race tracks Only seen them for the Nitro-3's.
'Rookie Solara' has a 'Wolfpack Radical's' clutch type 2spd on his belt driven Super Nitro. Check a few pages back for a description of his car.

Rookie Solara · #**334** 03-21-2003, 03:03 PM

Yes, I do have the 2 shoes unit on my SNRS4, the pad is from AE and the nuts/housing is by Wolfgang........I think that is what 2-speed suppose to be, not like the HPI single blade design.

About the Super in elect......I really doubt that it would even work, for a bigger heavier car, NITRO is definitely the answer......elect motor just cannot make that BETTER, and in ASIA (not sure about Japan).......Super class is even more DEAD then in state.......at least this season in Chicago, we have quite a lot of SNRS4 then Serpent IMPACT.........I think like at least 10-15 SNRS4 on each TRACK......no comparison to 200mm TC, but the Super Class is still here in USA.

wilson_bryant · #**335** 03-22-2003, 12:05 AM

ok i have three questions and cense you all own supers u should be able to anwser them:

1. my rear belt keeps getting nicks in it and i dont know what is causing it could it be rocks??

2. i got a fiber disk break in a trade and i am unableto put the metal pad, paper pad, break, paper pad and metal pad whe i go that way the screw hits the belt so i left out the last metal pad is that bad?

3. i just got a pair of powerline front shocks and the lime springs that came with the shocks make my car really low in the front is that normal?

Dropkicked · #**336** 03-22-2003, 12:25 AM

1. yes, your belt will get eaten up by rocks as will your pulleys. Rocks can also stop you dead in your tracks. Little teeny tiny ones too.

2. I would think that would not be good. But I have a robinson vented steel disc brake, so I can't help much on fixing it.

3. adjust the preload on the shocks. If they are threaded crank them till it's where you want it. If not put spacers in till it's where you want it.

I'm sure someone can give you some more info but..........

Hope this helps,

Drop

BTW I can't believe how FREAKIN CLEAN Rookie Solara's super is. Has that thing been driven??

wilson_bryant · #**338** 03-22-2003, 12:35 AM

thanks i just put the stock springs back on they are threaded, ill try and adjust it alot, i have had a big rock ruin my front belt just a couple of days ago.

popsracer · #**339** 03-22-2003, 04:41 PM

Pebbles, bits of Broken glass can cause a LOT of damage to your Car.
I actually ruined an O.S. 12CVR from running in the street. We had just transplanted it into one of our Reflex's and were test driving in the street to adjust the 2spd. A large pebble got stuck between the Flywheel and the Chassis, and stopped the Motor Dead in it tracks. This eventually (a few weeks later) caused the engine to EAT a Rod bushing, sending brass pieces through the entire engine. The ONLY salvageable part was the Carb.

Moral, I try not to run my RACE Cars in the Street at all anymore.

The Fiber Brake disc must be used only with the Stock Metal pads by themselves. A Metal Brake disc would use Fiber pads glued the the Metal pads.

If you can't get the Ride Height and Droop correct with the shocks, you may have to increase the overall length, end to end.

Are you guys all using universals, or have any of you built cvds for your supers? I'm having major problems with the (you guessed it) front left dogbone. No matter how much I shim it keeps wanting to pop out one way or the other, and keeps catching when i'm turning. Basically I want to know if they're worth the $30 for the universals.

Thanks,

Drop

popsracer · #**341** 03-22-2003, 05:16 PM

Ok Guys;

Here is a Picture with the New Fantom .15 installed:

popsracer · #**342** 03-22-2003, 05:22 PM

Guys;

Here are a couple of Pics, showing the Rear Camber Link Mod.

The Basics are to switch sides and flip over the upper Mounts, then re-drill to fit. Make a new Turnbuckle from a 4mm x 18mm set screw and mount the outer end in the upper hole as shown.

popsracer · #**343** 03-22-2003, 05:26 PM

Here is a Top View of the Mod:

I have CVD's in the Rear and Dog Bones in the Front.

Make sure the Outdrives and Axles are not grooved, or they WILL pop out no matter what you do. Replace them if they are Grooved from the pins on the bones.
Put a few (2-3) Shock O-rings in the Outdrives and Axles to keep the Bones centered and from popping out.

I have all of the pieces to do the CVD's in the Front, just haven't got around to it yet.
The HPI Universals wear VERY quickly and create alot of slop in the Drivetrain. Haven't ran the CVD's very much, so the Jury's still out on them.

Hope I helped some,

popsracer · #**347** 03-22-2003, 11:16 PM

wilson_bryant;

What Engine do you have?

How old (days/weeks/months) is the Engine in your Super Nitro?

How many Tanks of Fuel do you think have been run through it?

Sounds like one of 2 problems.

1) You have the High Speed needle set too lean and the Engine is overheating, then Vapor Locking at the Carburator.

2) The engine is simply worn out, and once it is warmed up, no longer has the compression to continue running.

Popsracer, are those foams?
