those look like jugg 2 tires and wheels, that truck is gonna be sweet!! Look out tmaxx... :D

[RC10T3]

holy cow!!! what kind of HP we talking about here? OMG .70....

[old phart]

Heh-heh, yeah baby................ :cool:

[KIWIRCGUY]

7 Shocks???? Does it have a 2 speed and reverse?? Or options for either??
Looks sweet though

[XXXER]

i agree with KIWI here, what is the deal with that? Seven shocks? Can we get a chassis pic? I am all sorts of confused!

[tperkins]

xxxer check out rc nitro.com hot products. there is a chassis picture

[tperkins]

i can hear it zoomin down my land right now. i might break a horse leg, but who cares :eek: :eek: :eek: :eek: :eek: :p :p :p

[tperkins]

whadya think about me puttin the fastest heli motor i can find in there thadle sure beat the maxxes :p :p :p :p :p :p :p :p

[SixVi6]

hmm it looks like anohter 1/8 scale buggy with an airplane engine it and big tires but who knows. it might be something to take a look at.

[MaximumST'er]

That looks like a Thunder Tiger Helicopter engine to me. I ran a similar .60 size in my Kyosho Convept 60. That thing will absolutely DESTROY the T-Maxx! :mad: It weights more, has more suspension travel, MORE power, and bigger tires.
YOu want some mustard on that T-Maxx pie?

Hmmmm, it seems you guys are saying the truck is better than the T when it hasnt even come out yet. The truck WILL have problems. Now, for the Thunder Tiger. It doesnt look to great. This thing has a .70?! What are we coming to? This is off-road, not on-road.

[RCCARTMAN]

I was told by a local hobbys store owner that 21 engines have some of the highest RPM and for RC cars and trucks. Isn't this .70 like a heli or plane engine with a RPM range between 500RPM - 20,000RPM, where a 21 can range from 28,000 RPM - 45,000 RPM. The 70 may have an advantage in that is has more horsepower, but in speed, come on now, how will it outrun a 21? Help me if you know.

[draggerman11]

I guess you could say because it has more power, it can turn a higher clutchbell, and that equals more speed.

[RCCARTMAN]

EXAMPLE:

Thunder Tiger PRO 70
2.5 HP @ 18,000 RPM
practical RPM Range 500 (Min.) - 20,000 (Max.)

OFNA Picco O-1 21 sized engine
2.5HP @ 41,000 RPM
practical RPM Range 2,500 (Min.) - 43,000 RPM (Max.)

Which is faster you tell me? The 21 sized engine rotates over 20,000 times more in a minute than the 70 sized engine.

[teamdilznic]

this new truck looks phat....Last time I checked monster trucks were all about acceleration...who cares if your .21 revs so high....it's not about speed...it's about torque and low rev power....the .70 has got to have gobs of torque for climbing over obstacles...did anyone notice that the truck didn't have slicks for on road racing? in the real automotive world, people put small high horsepower, high revving, low torque engines in on road indy cars....when was the last time you saw a monster truck running on anything but a blown big block...if you had a 4x4 truck that you went off roading with would you throw in a 200 hp,150 ft-lb 2.0 liter honda vtec engine or a 200 hp, 400 ft-lb 454 chevy big block? :mad:

[ammoace]

Just a thought but maybe the seventh shock is actually being used as a steering stablizer? You know, like what Rancho uses on thier full scale suspension systems. I say this because if you look REAL close right behind the front skid that looks like a shock might be laying down on the job there. :) I sure wish these manufactures would stop the body mounted insanely high thing. The body just looks like an after thought when they mount them this way.
Just my two cents,
Jerry

[BobHastings]

I just came in from the parking lot here at the show where we had a chance to see the truck go. (Rhyme unintentional)
Even with the engine slightly out of tune the EK-4 was rippin' the tires loose like mad!

[RCCARTMAN]

I have a TMAXX with a hyper 21, and have raced it offroad against guys that have the 40 engine and my truck burns theirs up everytime. I still dont get it, even in pulling contests, mine can outpull theirs. I thought that car engines and Rc car engines were based on different principles, so in comparing them there is a difference isn't there? We are talking about a 8-15 pound vehicle not 3,500 pounds. It doesn't take much to push these little things. give me a 21 and I eat that Thunder Tiger UP

[atm92484]

RCCARTMAN, how can you say that RPMs matter like that? I don't know about you but I'd rather have an engine with a ton of torque at 20,000 RPMs over some engine with more RPMs but less torque. With that extra torque you could easily gear it to make up for the lost RPMs not to mention the extra speed you could pick up.

[SVTMaxx]

Then the .40s that you were running against were either improperly tuned or weren't geared right.

[extremetmaxxer]

looks like everone is taking a jab at the t-maxx the seventh shock mystery

the shock is mounted horizontally between the front two arms as an extra dampning
i think there gonna have a ton of gear probs with truck

[cuttsv-spec]

I think that TTR is smart about joining in the monster truck craze. It seems everyone is getting one. But your choice is limited to a few competitive trucks. Say the TC3 was the only touring car out there. What fun would that be ?? Should there be a TMAXX specific class or should it just be a Monster Truck class ? I know the engines are different sizes, but cartman ^ seem to think it doesn't matter anyway. :)

[ProjectTwin]

Guys, I've seen a frontal pic of this truck. The 7th shock is mounted behind the front skid, right in front of the bulks. It sits between the arms and uptravel of either arm will compress the shock, exerting pressure on the opposite side of the front suspension, creating the effect of a sway bar. If you go into a hard left turn, the right front will compress, exerting pressure through the shock, and forcing the inside tire to the ground.

Neat stuff, might be a pain to tune, but it's more adjustable than a swaybar.

I'll try to dig up a pic of the front.

Actually, here's the whole link..

[Possumbot]

I was reading, but how do u start these things?

[ProjectTwin]

I think the long shaft in the picture is used on the black shaft sticking out of the crankcase, a Yank Eliminator type of set-up.

I bet you could use a starter box also.

Jason

[ammoace]

Gee I think someone mentioned the seventh shock looked like it was horizontal behind the front skid like many posts ago. Oh yeah, that was me. :p ;) :D
Jerry

[ProjectTwin]

Right Jerry,

But steering stabilizers help eliminate bump steer, this will help combat chassis roll when cornering.

Jason

[SixVi6]

Its still not a specefically designed monster truck like the T-maxx.. its another 1/8 scale buggy with big tires, a heli engine, and a couple extra shocks. So whats so great about it? you could put a .70 into a t-maxx I'm sure and you could probably also do the same to any 1/8 scale buggy or an MP. We'll see when they release it though if its any good. I'm skeptical.

[DirtRacinFool]

I like the .70 engine, but it still looks like its just another 1/8th scale buggy platform with Monster Truck Tires. :rolleyes:

[Throtl Hapie]

If an engine makes more horsepower at LESS RPM, than it's better! It will reach peak quicker than an engine that has to rev 2x as hard.

[atm92484]

And why is it soooooo bad if its similar to a 1/8 buggy with big tires? I'm still missing that part. Also you couldn't put a .70 into a T-Maxx. A .21 barely fits in there so how would you expect to put a .70 in?

[RCCARTMAN]

People of this forum, today I was challenged by a person who has modified a Thunder Tiger EB4 in to a monster, with a 91 engine. I must say I was impressed with its torque, it outweighed my TMAXX and shredded my CVD's in a pulling test. But before the pulling contest (where the 2 trucks are chained to each other in opposing directions) We raced up a 60 ft hill, with a 60-70 degree incline, and the truck lead for about four seconds, then I smashed full throttle and blasted up the hill. In the offcourse race with jumps and turns I busted that truck up again. It had killer torque but too much to control. I am not a good driver, and the other racer was, so was the other individual who dusted both of us with their 21 TMAXX's. My 21 TMAXX kills at climbing hills, and I haven't been beaten yet on a hill. This is why I just don't see this new Monster by Thunder Tiger being any better than this guys truck. As far as not being able to tune these trucks, the others guys tuned my truck and get paid to do this. If you love this new truck or the idea of this new truck then buy it. I am just saying that I don't think it is going to be as good as you all anticipate. I am getting tired of TMAXX craze and I am looking to buy a new improved truck that will crush it in competition. Maybe in a strength competition, or short sprint.

[SixVi6]

Yeah you could put a .70 into a t-maxx.. just extend the chasis. Thats how all the .21 kits work.. there are a ton of companies making extended chasis for the maxx trucks. I even know of a couple of them that will extend them to any length you want and no its no more than any other kit. In fact I got a quote for an extended chasis to my specified length and matching skids for under $100.

[ 09-09-2001: Message edited by: SixVi6 ]

[RCCARTMAN]

Which company SixVi6

[SixVi6]

Well I talked to Del of Little Fat Kid Racing.. they will do any length chasis. They were the cheapest and had good quality also. If I remember correctly that was for a 4mm thick alum chasis and rear skid plate and possibly the front too but I don't remember. they sell a .21 conversion complete with a TTR .21, ext chasis, front & ext rear skids, linkages, header, pipe and all for $299.. its a sweet deal. check the link below or post on the .21 forum at MaxxTraxx.com. He's always there.

That was a nice site. I decided to get on the net, due to the depressing TV coverage. May God have mercy on their souls and their families as well.

[beef_flavored]

what kind of suspension travel does this thing have?

[RCCARTMAN]

4 in the rear, 3 in front
