Duratrax, and thier Axis.. what can you tell me about it / them?

[Nitro_Dad]

I have an opportunity to trade something for either a nitro stampede or a duratrax axis.... I think the axis seems better...?

HELP!

[dcshoelover]

Well do you prefer an 1/8 buggy, or a monster truck? I have 2 nitro stampedes, and they rock. The aftermarket support for them is nuts. You can do alot with them. The Axis is great if you would like to get started in buggies. Not too much aftermarket support, but im sure that most major buggy components are interchangeable, like shocks and what not. And Duratrax has the best technical support Ive ever dealt with. Anything plastic you break you can send in for a free replacement. So it's basically up to your personal preference.

[Nitro_Dad]

is a 1/8 scale buggy much bigger than a stampede?

[dcshoelover]

I'll get a pic of my 1/8 gtp next to my stampedes ina couple of minutes.

[Nitro_Dad]

u rock :D

This is the first 1/8 car i've owned, and to me, this thing is just huge!!!!

my buddy has the axis. that thing is indestructible! he's had the thing 3 years (give or take a few months). all he's managed to break is an A arm (suspension arm), the front bumper twice (duratrax replaced the parts at no cost) and he wore out the piston and sleeve in the engine. there's no way to prevent that from happening, those parts just wear out over time in any nitro RC. cost him $50 for the new engine parts. those are the only "problems" he's ever had with it.

im just going to keep my mouth shut about the nitro stampede. lets just say i think there pure crap. iv dealt with 3 of them and all 3 have been junk. easily broken, and poor temperamental performance. and i can't stand the ez start that's on them.

[Nitro_Dad]

seems the same dimensions, plus the front clip. is the duratrax unit a good runner? our stampede .15 ez is not so ez :mad:

[Nitro_Dad]

can either one of these be made a rot start instead of that ez start and pull start? i hate the pull start bearing issues and the ez start sux...

[dcshoelover]

I've replaced the ez-starts on my pede's with pull-starts. They do take patience. But I've never had any major problems with breaking anything and im pretty hard on mine. Only problems I have are with the common traxxas engine overheating too quickly, but thats why they have larger heatsinks available. But I guess we all get different seeds. My buddy had an axis too, and I think the only problem he had was a stripped gear. But it's probly the best vehicle duratrax has to offer that I've ever seen.

Just about anything can be made into a rotostart. You just need one of those starter shafts and a drill. Alot of people just use a drill on the 1-way bearing. But like you said, the traxxas 1-way has alot of slipping issues.

[Nitro_Dad]

where do i find the parts?

[dcshoelover]

where do i find the parts?
For a roto-start? Ummm... been awhile since I've looke in any any stores r/c related. I would try www.towerhobbies.com www.stormerhobbies.com Those are really the only 2 i know of. Im other people will chime in. But I would say ebay is ur best bet! Just do a search on roto-start or rotostart or drill start under the radio control category.

[dcshoelover]

Or ya know if you get the buggy you could upgrade later to a better engine and a reliable starter box. But im sure the pull starter on the axis' .21 does just fine.

[Nitro_Dad]

oh ok, hmmm, the bearing in a drill, cool. right now the stampede has a MV12 engine in it, and cant keep the front wheels down :D but the pro.15 stamp carb dosnt work well on it and also cant find a matching carb or info on the engine, noone can which sux cuz it rocks, and cant find a matching pull starter either and this one is fryed. our original .15 has a fresh build but the ezstart kills the battery before it start, so far im hating the truck.

[dcshoelover]

Hmm I haven't heard of that engine. And why is the pro.15 carb on it anyways??!!! That's why I have pull starts on my pede's, no worries about dead started batteries and extra things to lug around with you. I've found the bearing only slips alittle when the engine is just starting and is cold, bt once warmed up alittle grabs just fine. Like i said, just takes alittle patience.

[Nitro_Dad]

cuz it came FREE with a slide carb, and wouldnt work, so i tossed the .15 carb on it and it rips until my son flipped it like 20 times :rolleyes:

[dcshoelover]

Heh! Maybe try rebuilding the carb with new seals, and check for leaks in the fuel tubing and the gas tank.

done, done, done, and triple done.... the low idle used to work great at 1-3/4 turns out...now it only works at 1/2 turn out...wierd.

[dcshoelover]

Hmmm...beyond me. If you haven't already, what I like to do is just take it all apart, put it back together with new parts if neccesary, return all screws and needles to factory, and see if that helps. What exactly is wrong with it? Does it run, run horribly, not run at all?

[Nitro_Dad]

it ran great til he flipped it bad a few times and now cant seem to get decent OFF-IDLE, and when I do, then it has no power and or dies alot, either accelerating or when you let off the hammer, it isnt consistant with any issue it changes and with making any adjustments. I am a master tech and a small engine tech for Stihl and Honda and this is baffeling me. the carb has been gone through 20 times and the issue will just come back. i just want a new carb and or truck.

[dcshoelover]

From my experience, which is little!!!! If it isn't idling good, or running consinstly, there's an air leak somewhere. I would check for cracks in the fuel tank. Even the littlest one which seems inferior will ruin ur day. And also check the fuel line or replace it. I think putting it in water and watching for bubbles is the way if I remember correctly. I ad a tiny crack in my stampede's tank one day and couldn't figure out why it wasn't running good. I must have thrown out 10 perfectly good glow plugs cuz of that stupid air leak!!! Also check the tank's lid seal, or if it has a primer cut it out and seal it off.

i had the same problem with my HPI nitro RS4 2. i flipped it a few times and then the performance started acting up and it became very hard to even start it.
turned out the piston and sleeve needed to be replaced. they were worn out. what i think happened (someone that knows nitro a little better may want to chime in here) was that when a nitro car gets flipped it starves for fuel. the pick up is on the bottom of the tank and when the car is upside down its not sending any fuel to the line and eventually to the carb. and with a 2 stoke that means lack of proper lubrication which tears up parts real quick.
i took the piston and sleeve out. then to check i just put the piston in the sleeve and pushed up, if it gets tight up at the top its probably still good, but if it doesn't, or the piston pops out the top of the sleeve like mine did, replace them.

DURATRAX IS OWESOME!, I have a Nitro Evader ST, and I LOVE IT, tough as HELL, only broke one A-arm, and It was my fault as it was my first nitro, but its really stong, duratax= A+

[MOVINFAST]

i have 3 axis ...they kick butt....i bought a nitro quake first but it was to sloppy with them big wheels.so i made it an axis instead.if you keep the nitro quake gearing it kicks butt on short track....if you run wide open speed use the axis gearing.....

as far as starting it i use a drill,,a dog bone cut on one end, and a drive cut attached to the shaft coming out of the engine...this shaft does 'not' spin once the engine starts so you dont need to run a one way bearing...fires up every time ;-)

[shadmaster4]

I have a Axis, and a Elec Stampede. While both RCs are one of the toughest in their divisiions, I would buy an Axis. They are much faster, 10x stronger, and larger... If you want to make the axis into a MT, just buy large tires, and smaller diffs (can be had for under $40 for the Diffs on e-bay). Or, just get a thunderquake. The only thing you may want to change when the axis engine wears out, is upgrade to a more powerful engine, such as the XTM 24.7 Threaded, or Mach .26 threaded. (Of course, SG shaft works too, but you have to mod the mounts.. )
