View Full Version : Dirt Runners 2010 Outdoor Racing Season - Oak Ridge, NJ
Mike, so you running 4degree (stock on PE) or 1degree toe-in on the rear ?
here is a pretty good starting point
got this off a team driver
Diffs 30k-100k-7k, or 30k-slipper-grease
Shocks 60wt front, 50wt rear, both in senod hole out on arm (stock front, in one on rear), middle hole on tower.
Aluminum rear axle carriers with 1.5 degrees extra toe-in.
1 degree camber all around
2s Lipo with stock gearing or +1 tooth on bigger tracks
Silver swaybars, flush links in rear and 5mm wire showing past the front links.
I REALLY recommend good tires, up to your track's restrictions. The best tire Traxxas makes is the S1 original slash tire.
i went with 60wt oil front and rear made a huge difference in handling..
cant really set it up with out a track but with a few minor tweaks truck is alot better...
Toby I'm running 1.5 toe in on the rear...
Duck395 01-05-2010, 11:46 AM That could be Howie. Is it right? Depends on the driver. Me personally, Im going to go a bit heavier. Maybe 50,000?
im sorry i just found the article. it said that they went from 30,000 to 100,000
on the fluid. sorry about that. i was going by memory which was my 1st mistake. lol

Thanks Mike :) I presume those Bling rear-carriers are not the Traxxas ones ?
spikeitaudi 01-05-2010, 11:54 AM Put the VXL in the tank yo!
I thougth about it. But the CAN size in the Tanks are no bigger the 460 sizes. :(

Coolio. good to know.
I was thinking the stock body seems pretty flimsy compared to the pro-line ones. I'm wondering if I should go with another Desert Rat (what I ran on my 2WD last year), although it weighs a good deal more that the TRX one.
spikeitaudi 01-05-2010, 12:10 PM I'm going to go with the Jconcept Dare body:

Jerzferno 01-05-2010, 12:45 PM So all you Platinum Edition guys thinks its slow? Must be all that aluminum weighing it down? Give me the Challenge TQ and 1st place trophy now. LMAO!!!
Duck395 01-05-2010, 12:49 PM anybody got a new mike jenkins or jerry welchel 4x4 body they wanna get rid of?i need one of each

Steve, Did you see my post about the weight of the PE.
I'm curious, how much does the RTR weigh ? thx

Haha. :)
tobamiester 01-05-2010, 01:43 PM Alvin, do you know when the Kinetic will be available ?

spikeitaudi 01-05-2010, 01:57 PM Alvin, do you know when the Kinetic will be available ?
I can't get one yet. :) I'll find out.
installed the new 1.5 carrier you can see the difference compared to the stock carrier...my bad for using photobucket link to lazy to resize pic's...

spikeitaudi 01-05-2010, 03:45 PM Toby, Novak is shooting for a January release, but it will most likely be pushed into February.
I just picked up my PE Slash from Jason. Haven't even broke the plastic film off yet. Will let my son break it open when he gets home from School. :)

Congrats Mate :) Definitely a moment to enjoy with the family :thumbsup:
spikeitaudi 01-05-2010, 04:19 PM Son got home and ripped off the film and quickly opened the box. Traxxas did a good job with the truck, but the clear body is so flimsy. Owell. Time to get the Jconcept body. :) Will be putting in the center diff this week sometime. Bind it up to my Dx3r and start figuring what Novak Powerplant to use.

I thought the exact same thing about the body. My 12th scale Pan Car body feels about the same :-p
I can't imagine these bodies surviving many 'turn 1' pile-ups :freak:
ta_man 01-05-2010, 04:57 PM Post on traxxas.com board indicate they changed from the planned .060 body to .030 body but didn't change the ad copy.
Jerzferno 01-05-2010, 06:05 PM Steve, Did you see my post about the weight of the PE.
I'm curious, how much does the RTR weigh ? thx
No I didnt. Did you weigh the PE with a receiver in it? Body on or off? Ill get a non-blinged 4x4 Slash weight when you tell me how you weighed yours.
Jerzferno 01-05-2010, 06:08 PM Bling envy again :hat:
Not in the least. I could have bought one, chose not to. Id need to spend an additional 60+ dollars for an Rx for it. Im gonna leave mine stock with the exception of tires and rims (Specifically made for Short Course trucks) and body and make you eat your blinged up words. LOL
solographix 01-05-2010, 06:27 PM You guys are funny, once Bob and Derek get their OFNA's its going to be game time! :wave:
solographix 01-05-2010, 06:29 PM Was there a proposed battery rule? 2S only? 3S? and up???
Lap Traffic 01-05-2010, 06:51 PM Game time? Game over!
I definitely need to get that Ofna soon so you Traxxas guys have something to chase.:cool:
Might not be lethal in my hands but, I can always turn it over to Stephen.:devil:
ta_man 01-05-2010, 07:45 PM Was there a proposed battery rule? 2S only? 3S? and up???
Proposed rule was any Dirtrunners legal battery. But since 3S, 4S, 5S, & 6S are legal for Electric 1/8th if sold under a brand that markets ROAR Approved 2S battery packs, I'd say let people use the same rules. If this is supposed to be an open class what difference does battery voltage make? Tires are always going to be the limiting factor, just like they are in E-8. It's not like you win on the offroad track by drag racing. E-8s are fast, but they have also proven that just running a 4S LiPo doesn't make the car uncontrolable.
This way someone can run a Novak 21.5/Mamba Pro and a 4S pack if they want to. Why not?
Jerzferno 01-05-2010, 07:52 PM So I can run 3 or 4 S in my sprint car, or 1/10th scale buggy as well? Those are mod classes. Lets not get carried away. Who has bottomless pockets these days?
Lap Traffic 01-05-2010, 08:03 PM If it is truly an open mod class, it should not be limited monetarily.
Just my .03
spikeitaudi 01-05-2010, 08:13 PM Don't you mean .03! If we aren't limiting monetarily. :) :) :)
tobamiester 01-05-2010, 08:55 PM No I didnt. Did you weigh the PE with a receiver in it? Body on or off? Ill get a non-blinged 4x4 Slash weight when you tell me how you weighed yours.
Hey my bling-deficient friend, My Stock Platinum (with crappy stock body w/out body clips) with an SR300 spek receiver installed , 5lbs 0.6 oz. :)
tobamiester 01-05-2010, 08:56 PM You guys are funny, once Bob and Derek get their OFNA's its going to be game time! :wave:
I have to admit it, as ugly as those SC OFNA's are, they seem to really perform well :dude:
Lap Traffic 01-05-2010, 08:59 PM I have to admit it, as ugly as those SC OFNA's are, they seem to really perform well :dude:
They look good from the only end a Slash will see, THE BACK!:lol:

Tobey - I got 4 pounds 13 ounces.

I agree. Go for the 3/4/5/6s packs You'll be begging for traction. Its going to be funny when I school all you hopped up guys with a stock (except tires and body) 4x4 Slash. Especially those tanks.....................I mean OFNA's. LMAO.
tobamiester 01-05-2010, 10:26 PM You're pretty much saying then there are no rules and the skies the limit? Anyone who doesnt have deep pockets should know now that they will be running against high dollar vehicles and have very little chance of winning? What kind of a message does that send to the new person starting out? Or the financially strapped person? Or the kidwith great expectations? Does this go for ALL classes? Im ASKING because I want to know what you mean? My thouhts on the class is its a mod class, not an open class where anything goes. Theres still rules in a mod class.
Lets keep the rules discussion for Jan 17th. Lets get back to the OFNA/Slash Smack Talk.... :)
tobamiester 01-05-2010, 10:27 PM Tobey - I got 4 pounds 13 ounces.
Not much in it then really. pretty neat.
I just picked up a body for my PE. Going with same body I run on my 2WD, Desert Rat.

Toby you install your center diff yet? I just installed it and now when I roll it it has that shutter feel like in my 1/8th scale instead of it being smooth when it had the slipper clutch. That is correct right. Just wanted to make sure. :)
Jerzferno 01-05-2010, 10:33 PM Not much in it then really. pretty neat.

Sounds good to me. I was PMing with a member on this site in another thread. Said he picked up an OFNA SC truck. Said its very heavy.
spikeitaudi 01-05-2010, 10:35 PM Sounds good to me. I was PM's with a member on this site in another thread. Said he picked up an OFNA SC truck. Said its very heavy.
That is why they are probaly using the HV Pro Novak Brushless motors.

So the Clear bodies are really thin eh?

Sprint Car was a pre-existing class that had a 6-cell Nickel or 2S Lipo rule. In fact, what difference would it make if you ran the sprint car with 3S or 4S as far as the competition: We already have more power than can be used with 2S LiPos. No one runs the most powerful available motor in that class. It has been shown in E-8, higher voltage, by and of itself, doesn't mean more power. It just means more efficiency. So in Sprint car you could run maybe a 10.5 on 3S and be just as fast, but have the motor/speedo run cooler.
As far as the expense issue, look at ProMatch LiPo batteries. Their 3S hard case LiPo costs less than their 2S hardcase LiPo:
http://www.promatchracing.com/proddetail.php?prod=3S3400
http://www.promatchracing.com/proddetail.php?prod=4506
So if someone was getting a battery for their 4X4 Slash, they would save money buying the 3S and could buy a smaller pinion with the savings to end up with the same, usable speed.

Mark it makes no matter to me anymore. Im staying stock, will master the set up, and school will be open. LOL So you getting one or not? You have a lot to say about it. I bet you already have it? Come on Mark, come clean with us. LOL

To be honest its still on my desk in the 'To Do' section, with all the other Outdoor stuff...I wish the darn glacier in my yard would thaw, then I can get out there and test it.
Matt. I'll prolly bring it to DR on Saturday so you can take it for a spin (but don't be selling that RC8e). I suspect there will be a few there mind.

Your no help. :)
I am pretty sure it is right, but posted over on the traxxas site to see what the feedback from somebody that has done it already. Will let you know. :)

We'll see. If this class is going to be as contentious as the 2WD Open SCT, I may want to keep away. If it was an open class, like we could run whatever motor and battery and tires we wanted, I would be more interested.
What got me interested in 1/8th scale to begin with was that it didn't matter what car you had. I just didn't want to have anything to do with Nitro so I did an E-8. And then we had that big to-do about 4S vs 6S batteries.
Maybe 2S is the way to go, or maybe 3S/13.5 will be the way to go or maybe LiFePO4 and a 6.5 motor will be the way to go. Aside from the driving issue, if I beat you with a 3S powered car it would be because the power level was suited to the track conditions, not because my battery had more voltage.
ta_man 01-06-2010, 12:17 AM I've something to add regarding battery voltage selection.
I think most everyone here knows I have a Slash set up with 1/8th scale buggy tires and a brushless motor. I ran it one day when we had some 2WD SCT mod entries. The motor in it is a Novak SS5800 with a sintered rotor. The suspension is stiff because I run it on the street, mostly with the gryo, so I can do some 2-wheel antics.
What you may not know is that, during warmer months, even though I have a heatsink on the motor and a fan blowing on the heatsink, I cannot run more than about 1/2 of a 5000 LiPo pack before the motor thermals. Sure I could gear down, but doing so makes the truck slower. And it wasn't by any means, noticeably faster than the stock Losi SCT when I ran that one race. I think that the 5+ pound weight of the Slash with battery is just too much for the 540 size Novak to push around for an extended period. Those motors were designed with 3-4 pound vehicles and 3000 mAHr batteries in mind.
Now consider this: Instead of running a 8.5 motor (the 5800 is an 8.5) on 2S LiPo with a KV of around 5200, I could use a 3S LiPo and a 13.5 motor (KV of around 3300). I would gear the motors exactly the same because the voltage times KV would be the same. I would probably have about the same power and the truck would go about the same speed. The Truck would weigh the same with the 5200 2S LiPo or the 3400 3S LiPo.
But the current going to the motor would drop by [about] 33%.
With that the heat generated in the motor would also drop by about 33% (Heat losses: I squared times R: current down by 1/3, resistance up by 1/3, but current squared, so heat loss down by 1/3). So I would be less liley to thermal and could run a full battery out in a practice session.
I realize the thermalling issue may not apply to the VXL because it is a dfferent design motor, but some people may want to use sensored motors for racing and so my mention of the Novaks.
Before someone mentions that pan cars have gone the other way with voltage, lets note that this change was done to slow the cars down within the limits of readily available motors. That is an entirely different issue and not revelant to the selection of battery voltages for our outdoor classes.
Lap Traffic 01-06-2010, 07:36 AM I agree. Go for the 3/4/5/6s packs You'll be begging for traction. Its going to be funny when I school all you hopped up guys with a stock (except tires and body) 4x4 Slash. Especially those tanks.....................I mean OFNA's. LMAO.
I never said I had any interest in running the highest voltage pack I can find or the most expensive options. I will be running 2s pack as that is what I currently own and whatever comes in the box. I DON'T wish to spend a ridiculous amount of money to run the class. I completely understand tires are the limiting factor, not how much power you have.
It is simply my opinion that a mod class should not be limited by what some people can or cannot afford.

Right from the Rules on the website
For Slash
"Batteries: ROAR approved 6 or 7 cell sub c industry approved standard rechargeable battery or a ROAR approved 7.2V LiPo Battery only."
Of course that means 7.4 not 7.2 - it will be updated after the rules meeting.
For most other classes
"Batteries: Roar approved 6 cell sub C battery pack or 2S ROAR approved LiPo battery – see general rules, batteries (March 2008)."

Thanks for the clarification Bob. Thats the problem with the internet. You read what is "typed". Theres no tone of voice connected with it which can set the meaning of what is said. Theres no immediate question "what do you mean by that"? Thats why I had to ask for clarification.

I think this just about wraps up that discussion.
