Hi Gang,
first let me say I "searched" the forum to death for info and opinions of the XTM 1/8 Mammoth ST. I already know the Opinion of "REVOFAMILY" and do not need your input, as I know you think it is junk ,and I do not want this to become a flame war.
That said, I am considering going to 1/8 scale for just all out fun bashing and the need to add someting else to my collection. I already have a REVO, and a handful other 1/10 and 1/18 scale trucks and buggies.

Anyone have one?, what are your thoughts and suggestions to me in my quest for a new truck?
Thanks, JOe

well seeing how its no where NEAR a ST truck.....I know nothing.

If it is not a ST then what is it?, Looks like a Stadium Truck to me [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKYZ7&P=ML]stadium truck picture?[/link].... just bigger than yours, and at 48.8 MPH radar tested by RC Car Action is is probably faster too
JOe

I think that thing is going to be a winner

It isn't an "ST," It's a truggy, like the Hot Bodies Lightning stadium, only bigger. I have one and I love it to death, for $340 bucks its the best RTR on the market in my opinion. It really is race worthy right out of the box. I'm taking mine racing tomorrow. I'll be racing it box stock, except for 40wt shock oil all around. It comes with 100wt oil for bashers, but it's just waaayyyy too thick for racing. It comes stock with a 2 speed, but there is also a center diff available, which will make it way more compeditive. You can also get a 290cc fuel tank for it and it will bolt right on. The only thing "ST" about it is the body really.

1)Its too big to be a stadium truck let alone RACE with stadium trucks(I hear its in the MT class)
2) its a 1/8 scale
3)Giving its size/weight/speed it will most likely race with the Monster trucks
4)Yes, the name has the "ST" in it, but thats for confusing people into buying it

I just got my RC mag and i did on it however. Looks good, but nothing special.

Honestly it looks like a truggy, only 4 shocks, has that buggy tub look, and has some really long arms. And even in this magazine it says at the end of a paragraph "The Ultimate Monster Truck Racer" Now I dont know about you, but if this really is a ST...why is it in the MT class?

I saw one at my lhs. It was love at first sight. Looks awsome and the price with that beast of an engine, sweet deal. I was thinking of selling my Jato for it. Im gonna wait to see what the Ofna Jammer is all about first. There are gonna be lots of new truggies coming out and Ive heard about some diff problems with the Mammoth ST and those are the worst kind of problems imo.

Take some pictures, I want to see it!!!

" Now I dont know about you, but if this really is a ST...why is it in the MT class?"
Good point, I had a hard time trying to figure out which forum this thing fit into from the beginning, looking at the specs compared to an Associated MGT , I now see why I stand corrected
Joe

BTW: MGT of Mammoth ST, both similar in price, ?????????? , Hummm.

actually, the diff problems were addressed in the ST, the original mammoth is the one with diff problems.

I only quote things I have witnessed first hand. Thats why I get so mad when people bash the Jato and have never seen,heard,read of anything bad about it.
So...
At my lhs a week ago 2 new mammoth st owners were up there running thier new trucks in 2 wheel drive becuase both of them had burnt up thier center diffs. In the first 10 tanks[X(]

Thats not the only reason I didnt get it though, my lhs does stock alot of xtm parts.

the mammy ST doesn't have a center diff:P they probably toasted a driveshaft or something

No, the Mammoth ST doesn't come stock with a center diff. No, I doubt they toasted a driveshaft, those things are THICK! I'm willing to bet my truck that a drivecup just came loose. Like you should with any RTR, once you get it you should take it apart and rebuild it using loctite on metal to metal screws. The drivecups come loose from factory because they use this goope that shouldn't even qualify as a threadlocker.

valve...i know the drivecups on my X-terminator have come loose a buncha times..hadn't thought about that, but i've also toasted more than a few dogbones

Well , I've decided the Mammoth ST is going to be the next truck. I already have a Revo for bashing and hill climbing, an evader ST ( Nitro and Electric) for playing in the street and an Axis Buggy that I never take off the shelf, oh yea and an RC18T for wintertime indoor playing. I think the mammoth ST will be a great jumper and a fast all out basher in the big dirt fields. I love fixing things so the duribillity is less of an issue, I will overlook some poor design flaws to have a fast truggy, besides I think each persons opinion of durable varies with their experence with driving the thing( I have broken less parts as time rolls on).
joe

Tell us how it works out for you, if towerhobbies ever gets replacement parts for it I might get one also. I just saw a video of it...

blah, F tower!
www.HobbyPeople.net carries parts for it, and the parts ARE dirt cheap.

i just recive my mammoth st the ting that i didn't like is that in tower spect says that it come with steel spur and it dont and if some one know what kind ob bodys can you use on it please let me know

Jimmy, a steel spur is fine as long as you know how to set your mesh. I've been running the same steel spur on my x-terminator for well over a year and through about 7 gallons total, and the CB and spur are still in great shape.

im a proud jato owner but I wanted something to race in the truggy class also, I wanted to get this truck but then found out my father wanted to get a truck.... so I suggested the mammoth st. we got it at the lhs for $339 from $399 they were very reluctant but I was'nt playing w/ them. We have no complaints about the trucks driveability or handling. I belive it is by far the best value out there. The ONLY complaints I had about it was the philips head hardware, and the .247 motor came out of the box all out of tune. It handles like a dream and is unbelivably fast for a 10lb truck.

There is a HEX head hardware set for the original mammoth available, I understand most screws will ft the ST. I will probably replace screws w/hex as I repair the truck over time,Joe

The ST in the title came from one of the racing series that was making the truggy class the "Stadium Truck" class. and they were going to make the 1/10 2wd truck the "Nitro Truck". Well they didn't end up labeling them all that way.

The Mammoth ST definitely should race in the truggy class since it's size is 1/8th scale but it was not designed from a buggy like all the other Truggy’s. It shares front/rear diffs and shocks and that's it. The rest of it doesn't resemble a buggy at all. Which I think is kind of cool just like the New Jammin truggy is actually built from the ground up and not just a converted buggy (but it's design originated from a buggy).
As for the engine arriving out of tune, that is to be expected! If the manufacture is in Southern California and it's 70 degrees with low humidity and then send it to Florida where it’s most likely hotter and has much higher humidity, you going to have to tune it! I have never gotten an engine that didn't have to be tuned.

For the money, the Mammoth ST is a great deal with a great engine. I think I might have to get one to mess with. I was impressed on how much power and how well it handled the ruff track. You definitely get a lot of truck for the money.

OK maybe someone can answer my question, im new to 4WD rcs and am getting a mammoth st somtime soon but was wondering what the advantage of the center diff is?? I have no idea what it does, also what do the different weight oils do in the diffs??

thanx for any help

the center diff helps a LOT with handling. you can tune it with different fluid weights to change the dynamic power distribution between the front and rear wheels. you might get a bit more help from the 1/8 buggy guys though. I know what the advantages are, just not terribly great at explaining them.

I have one, and I love it. It's fast, and durable. I stress tested the crap out of it yesterday, and it held up pretty good. I took it off of a hill that is about two feet high on one side, and on the other drops down about ten feet, so with the added air i picked up on the jump, it was crazy. Then, I decided to hit the jump by coming up the ten foot side. I haven't quite got the hang of leveling out my jumps, so a lot of my landings were less than perfect. Infact they sucked, and most of them included either coming down on the rear bumper, or on the top of the truck. At the end of the day, I ended up breaking one body mount, the front left CV shaft (the little pin on the end) and cracking one of my wheels. Not bad considering the hell I put it through.
