Can you help me. I find the rear diffs slipping and noisy. When I strip I dont see any problem. Any of you guys experience this problem? How do you solve a noise rear diff. I think its the pinion gear slipping on crown.

You need to shim the diffs to keep them from clicking. Racernine.com has a very good explanation of how to do it. http://www.racernine.com/outlaw5.html
Another way to fix it is to get a center diff.

Hi,

I use to have a mammoth...strangely enough, I couldnt get on with it. It kept smashing the front CVD's and no matter how often I replaced them it use to eat them!! Mind you it was fast like you wouldnt believe. I was impressed with it speed, but I did not like repairing the front CVDs nearly everytime it went out. I wasnt even jumping the thing!

It all depends on what you want out of your engine. I'll just assume you want something for all around so I would recommend the Jammin JP-3, it's a little pricey but it will do wonders as far as improved performance. There's more expensive pipes but the JP-3 performs well, but at the same time, it's reasonable in price and should work on the stock 24.7 engine. If anything, you might have to do very minor modifications to get the pipe to mount the way you want it to.

Correction for ssj2.
Here's how the JP pipes works:
JP-1: gives you more torque; best for engine which lacks torque, or if you just want more torque.
JP-2: Gives you more topend. Best for engines such as the Axial, which have plenty of grunt, but lack top-speed.
JP-3: Boosts the midrange. If you have good acceleration, and good topend, but your midrange is flat, this pipe is for you.

It's not a best all-around pipe, but each pipe has its purpose.

Just clarifying for you Steven.

P.S.: I also recommend the Hitech 5955TG, and I hope ssj2 likes his revo.

All I said dude that the JP-3 would be his best bet for midrange/all around. You know that happy middle? Geez, the flaming and all that crap has gotta go. And it's HITEC, not "Hitech". Yes, I do like my Revo too, with the 18TZ, it's gonna be sick. I'm glad you're enjoying your servo and everything, I"m glad I could help you out. Just don't flame and all that because I only specified the JP-3 as a decent all around pipe for somebody who doesn't want a "biased" pipe if you will that leans towards one spectrum. Let's just let this lay...

Steven, nowhere did I flame you out. I simply stated what each pipe does, so the man can choose for himself. After I saw this: "I'll just assume you want something for all around" I decided to help you out with your description of the product.

Yeah, by all around I meant a mid range pipe. Something that would benefit not specifically the lower or higher end but something that would be a middle point. I know each function of each of the JP pipes, and I figured the JP-3 would be the best for DiscoStu. Just let it lay, done deal.

ssj2 you're right the jp-3 is a GREAT all around pipe. i have run all 3 jp pipes on my axial .28 rr mammoth st and all are great but the best all around pipe is def. the one.

I just pulled the trigger on a Mammoth ST. I was gonna go pro, but I don't have the back catalogue of radios and motors required to make the most of the chassis. I'm going to gradually hop it up to pro spec, center diff, chassis, braces etc.

It's a hot looking truck for the money, irrespective of the haters in here. I found the repeated bleats of 'save up a bit extra for a Savage or a Revo' positively hilarious. In the UK the Mammoth ST is about £220 (i got mine for £200) or about $380 US, the Savage X RTR is over £345, or about $680, the 3.3 Revo is about £330, or $640.

As you can see there is a fair old price difference over this side of the pond, and if the Mammoth needs a set of chassis braces at £35 and a center diff or even steel spurs for £30 a piece then it'll damn well get them for the money.

I have to agree. I have had my issues with my mammoth ST, but for $350 US (hobby people price) you can't beat it. New buyers just need to be aware that you will most likely have to shim the diffs right out of the box.

my modded mammoth st
I painted proline crowd p. body from a jammin x1-crt. Fits good with body mounts flipped to outside of uprights.
bigair.com arms--awsome
rcvisions.com hinge pin retainers
i machined 7075 alum. center braces(work at machine shop), also machined wing mount-8eight and proline wings
center diff.(100k oil), shimmed orig.front(50k), shimmed orig.rear(30k), handles very good
hitec 5955tg steering servo---worth the high price, 90 oz.fatuba throttle/brake servo(forgot#)
alum c-hubs
mounted battery up front for better steering--seems to work good(might try to mount further back, next to fuel tank, on top of brace.
mugan alum. shoes with 1.1 springs
proline 1/2" offset rims with bowtie mtr's and panther camoto dragin Lp's.
offna offset rims with crimefighter mt's
axial beadlocks with bowtie 40's
just ordered an RB modified sts .30 and o.s t-2050 pipe.
now I just need more practice driving and racing.











older pic with orig. body, xlb wing and mount axial beadlocks.

Nice I will have to send some pics of my mammoth I think everyone should go straight to a metal gear. I hate that the pin keeps breaking in the steering knuckle causing me to loose four wheel drive I would like to go to a dog bone set up any one know where I can get the parts?

I'm happy to see you got everything back together alright Nick. Your bro's truck really looks great, perhaps you can get a little video footage when he takes it to the track tomorrow. Again, nice job on the build and thanks for posting those pics.

No video unfortunately. I am buying a new camera and testing out the one I want. It doesn't have vid so pics will have to do.

He only got a lap in before running into some steering problems. We couldn't get a plastic servo horn to hold up? You guys running aluminum?

This is all ya get for now!



Doh!

I think aluminum is a must for the servo horn. It also stiffens up the steering a little bit, I noticed the stock "arm" (if you want to call it that) had a lot of flex in it.
