I am a current HP Savage 21 owner. I have been thinking of buying a new HPI Savage 25 (bigger engine/electric starter) are the real selling points for me.

However, just saw many great posts on the Mammoth in this forum. For the cost of the Savage 25 I could get the Mammoth and the rotostart.

Anyone on here upgraded from a Savage to a Mammoth. I would love to hear your opinions.

MAMMOTH TOUGH

It depends if you are a basher get a savage if you want to kick some major ***** on the track then a mammoth is the one for you. My Pal got a Savage 25 and i got the Mammoth at about the same time so i know the savage is more durable for bashing but when something did break on the Sav it took him 2 times longer to fix it, The Mammoth on the other hand is very easy to work on and fast to fix so IMO if you want a hella fast truck that is tough! get some supports for the shock towers and/or a roll cage and you are set With the Mammoth!....hope this helps
Oh and the rotostart is kinda nice to have but not needed on the Mammoth the 247 engine is way more reliable then the .25 or .21!!

worst thing about a mammoth, or any xtm is that it is a global hobbies product, and they are like sams club for hobby stores. the stores have to pay like 500 bucks twice a year to sell their stuff, and most places can't afford it, so they dont deal the stuff. on my x factor, i always have a week of down time when something breaks. on the savage, about a day, by the time i go to the lhs. on the t maxx, its just a matter of walking around the park long enough to find the part you need in the grass, because there are a million maxxes out there and odds are someone has left an extra part around somewhere (kinda like the chevy 350). that and you can buy t maxx parts at mc donalds.

MAMMOTH TOUGH

he has a good point but if your LHS has xtm parts go for it I live in Winnipeg and b4 i spent the cash i wanted to know how many parts they had kicking around for it, and THEY had LOADS So if they have to pay 500 every 6 months wouldnt it make sence to realy sell there parts! IN A BIG WAY! IMO if your LHS has XTM parts GO for it!

Totally agree. I have a Hyper 8 Port Savage, and a Mammoth. In RTR form, I would go with the Mammoth. The servos are excellent for an RTR kit, and the latest ones come with the Agressor radio, and not that nasty-looking Lynx. The only drawback with the Mammoth is that you will need the braces or roll cage as MAMMOTH TOUGH indicates, otherwise you WILL bend the shock towers. It's a really fun truck...big air because it's fast and light, and other than the shock towers, very durable. Make sure to get a failsafe and receiver pack.

The mammoth is heavier than savage................

Cal-Torque

Did I say otherwise?
Regardless, if you consider the size to weight ratio, the Mammoth is light for it's size.
It's substantially longer than a Sav, and about the same width (I just looked...not referring to specs).
With piggybacks, heavier GPM TVPs, a tank guard, and centre skid, my Sav makes up the 1/2 lb difference.
Both are great trucks. I'm just having more fun with my Mammoth currently.

Hey Cal-Torque, does your Mammoth handle well on a tight track or do you need to keep the rpms up? I heard they were a little sluggish off the line. BTW, my Mammoth should be here in 5-8 business days!!!!!!

MAMMOTH TOUGH

I find mine is very good off the line i think the ppl who assume they are slugish have never even seen one go all they know is that with a top speed of 52mph the bottom end has got to suck....WRONG the 247 has more power and more TOURQE there for it can be geared higher
.....i know you didnt ask me but i figured it would be worth a shot

instead of buying an all new Savage, how about you take advantage of there engine exchange program, send in your .21 for the .25 and pay a discounted price, pick up the roto start if needed

with a few minor upgrades the savage .21 and .25 are almost the same, it would be cheaper to upgrade your 21 to 25 specs, then buy new

I listen to everybody as long as they are not bashing....

Cal-Torque

I'm just a basher, not a racer. But, I don't find it sluggish. The turning radius is pretty tight, and the steering servo isn't that slow (as some people have suggested).
I actually put a spare Ofna .25 in it over the weekend, and it performs just as well as the XTM 24.7...maybe a bit more top end. A neighbor with a lead sled Savage (way too much al on it) was out too, and the Mammoth made it look like it was standing still (understandably)...

Mxracer45

HMmmm ofna .25 has less horse power. But i guess it has more rpms i guess. I wouldnt think the mammoth steering is sluggish., It has a 175oz steering servo

hobbypeople.net has the mammoth for 389 thats 52 mph savage 409 40 mph and the t-max 389 around 40 mph
i think its time to get a mammoth

Cal-Torque

As you know, specs aren't everything... There are a ton of variables, and motors will be different due to production issues. Regarding the servo, slow refers to speed, not torque. Speed on the XTM X-175 is 0.22 per 60 deg (I assume at 6V), which is not very quick. As comparison, a Hitec 5945 is rated at .13 with 181oz of torque; of course, it's a more expensive servo. Regardless, I'm happy with the stock XTM...works good so far, and it's quick enough.
On the engine, posted specs are questionable at best anyways... On paper, the difference in hp between the Ofna .25 and XTM 24.7 is just over .1 with max rpms at 10000 difference... That doesn't seem likely. That would mean that the Mammoth should be 35% faster at WOT with the Ofna .25.
