:surprised:.... Gosh... it's such a beautiful build... That all black hummer body sure adds some personality to the truck... it seems pointless to compliment you on the design and build because you
already know it looks so damn good... but, I must... great work man... the thought process and engineering that went into the truck is just outstanding... I am sure if you got these parts in the
aftermarket seen, they'll do very well... glad you could share it with us here.

You hope we like it???? How could we not!!! Definitely one of the most epic builds ever. Very well done.

el tomaso 05.03.2010 01:18 PM

The greatest build ever!

Indeed very very good!

JAILBIRD 05.03.2010 05:41 PM

WOW!! Very nice work.

I have a CNC Router and have been thinking about making some custom parts out of carbon fiber. What kind of speeds and feeds (tool RPM - cm/minute) did you use to get such clean cuts? This is the machine I have:

Thanks!

rc4x4nut 05.04.2010 07:57 AM

Damn that is a beautiful truck. How rigid is that chassis with the cage? In some pics it doesnt look like it has any bracing lick the truggy chassis.

Also, a stretch, but have you thought about doing a limited production?

Stumpjumper 05.04.2010 10:17 AM

@ all - thanks


@ rc4x4nut - Yes I think about a conversion kit but not full. Only for the normal Nitro-LST´s. There are so many things I arranged in the gear box. The motor mount is so complex. I don´t want to build it again.


@ JAILBIRD - I use VHM tolls (VHM = Full Harded Metall). We used it normaly to cut hardened steel (about 58-62 HRC).

If you toke normal tool stell cutter it´s blunt very fast. Speeds and feeds - very slow! It´s a matter of feeling. Also lining. Carbon is so disgusting.

And don´t forgett to exhaust! We have a very big exhaust system. It´s the big pipe you can see on the pics...

http://i441.photobucket.com/albums/q...s/P1140710.jpg

and the smaller one I normaly use for this stuff

You are an inspiration. This build is extraordinary. Makes my builds look like child's play. I don't use a CNC, I don't have the knowledge to use them (yet) or the CNC machining either. I do most of the stuff by hand but for cutting CF, diamond disks make a very clean cut. For making holes and counter sinking, Carbide or Tungsten carbide bits and end mills cut through CF like butter and also make very clean cuts. I can only use high speeds because I make the cuts with a cheap router on a small router table and it only has one speed, fast :mdr:
Thank you for sharing this build, it is truly wonderful.

suicideneil 05.04.2010 02:11 PM

Well, thats another truck I have to inseminate I guess...

Awesome setup you have there, turned out some truelly stunning work with it. :yes:

Stumpjumper 05.10.2010 10:38 AM

After 3 run´s....

http://i441.photobucket.com/albums/q...s/P1140774.jpg

It´s still the first slipper. It alived the nitro stuff and the last conversion whit the Big Maxximum at 18 NiMh Cells. But now I need a new one.

nitrostarter 05.10.2010 10:53 AM

Are you going to manufacture your own?

Chadworkz 05.10.2010 11:58 AM

Holy Crap! That is just plain awesome!

What's_nitro? 05.12.2010 03:34 PM

Very nice! The CF should hold up much better than the plastic pads did.

Looks good tho!

Chadworkz 05.13.2010 12:44 AM

That looks like an NHRA Top-Fuel/Funny-Car Clutch Setup...very nice, and very well done!

What size and weave is that carbon-fiber? I can't tell since I am unsure of the physical dimensions of that clutch-basket, but the weave looks a little too course for the application. Is the CF weave uni-directional, or is it a minimum of bi-directional?

I think you will need a minimum of 3k 45° bi-directional weave to sustain the pressure & heat that clutch is going to see, for sustained periods of time.

Anyway, regardless of what type/size of CF it is, the clutch looks awesome, and you did an excellent job making it...congratulations!

Stumpjumper 05.14.2010 03:27 PM

@ Chadworkz

I don´t know nothing about this substance. I have so many carbon odment. Look:

http://i441.photobucket.com/albums/q...s/P1140791.jpg

more important than the wave is the thickness. I need the size of 1,35mm.



Today I graduate the first test drive whit the new carbon slippermpads. But the slipper was a littlebit to close. So the car was to wheely-joyfully.

[YOUTUBE]4FSutEUdRT8[/YOUTUBE]


And don´t wounder about the wheels. The rims haven´t enough offset and the tires grind on the body. But I want to test this to.

The tires are made of old LST Claws. I cut all the blocks of and grind them clean. Looks ugly but drive well....

ANGRY-ALIEN 05.14.2010 03:58 PM

The new look is just bad a$$!!.... you can send me your carbon scraps if you wish... I'll dispose of them appropriately...:lol:

suicideneil 05.14.2010 03:59 PM

I wondered what those tyres were- clever thinking. That truck definately flies when you give it some throttle, need a runway.... :lol: :yes:

Chadworkz 05.15.2010 04:47 AM

In applications such as your clutch disks, you need carbon-fiber that has a very small weave pattern (3k to 8k weave). It looks like you have everything from 500 weave to 6k weave in your scrap kit, so if you need to make new clutch disks, use the scraps with the smallest weave pattern.

The thickness is one thing, but it's the weave and the direction of the fabric that make the biggest difference. 1.35mm 500 weave uni-directional CF won't last long as clutch disks, but 1.35mm 6k weave bi-directional will last forever almost.

jappow 05.15.2010 06:31 AM

Awsome build, I give you lots of props! Man you must have like a million hours of R&D between design and fab. One thing if I may ask you. The servo saver you have , can you share some info on it, like if it was made or bought and if so where I can get it from?

Stumpjumper 05.15.2010 08:04 AM

it´s this one http://cgi.ebay.com/HPI-SAVAGE-SILV-...item20b0f8ec4d

but I modify a littlebit

mistercrash 05.15.2010 08:18 AM

Your CF slipper pads look really nice. Your work is always awesome. I tried a CF slipper in the past on my E-Revo and it ran for a while but eventually failed due to heat delaminating the CF layers. Heat breaks down the epoxy. The solution for me was to make aluminum slipper pads. Not too long after, Traxxas introduced aluminum slipper pads for their new brushless E-Maxx. I am still running the same slipper pad I made more than a year ago. It seems to be indestructible and lasts for a very long time. My thinking was: If aluminum is good enough for clutch shoes on nitro cars, then it will be good enough for slipper pads on brushless systems.
Just another option if the CF fails. I hope it doesn't

He was asked about the runtime he gets on a pack of batterys on that truck.
He stated he would get just under 10 minutes of runtime if he's full on the throttle during the whole time, "until his motor starts to glow". He also plans to do an uncut video from when he plugs in the batterys to when the LiFeDimatic kicks in within the next few days.

I hope this is a sufficiently accurate translation.


Apart from that, love your truck man!

CF starts to break down at 60-70C doesn't it? The clutch will get higher than that I expect.

Stumpjumper 05.15.2010 03:33 PM

I copy the full thread at the german forum and forgot to erase it. I only needed the photobucked links. Now its edited...

and yes - the translotion is correct.

I´m bored today so I decited to make a new vid whit other tieres. And whitout body because it´s to havily above and the car dosen´t make wheelies.
You can see it in the vid from yesterday too. I put it off and it drive "normal".


so here it is...

Your level of perfection far exceeds most, not only with your inspiring build but even with your video editeing.
Great work, you have humbled most all of us here on RCM.
Thank You for sharing !

Krawlin 05.15.2010 05:50 PM

Not only did you raise the bar with this truck, you pretty much put it out of everyone's reach. Awesome truck, looks like a lot of fun, good to see you drive it and it isn't a shelf queen. :great:

If I had the equipment though, 1 thing I would do differently is make the arms longer and beefier and use taller tires. IMO it would look even more amazing than it already does with that Hummer body.

Chadworkz 05.15.2010 11:09 PM

I absolutely love this project, but in the video, it looks like the truck is only 2-wheel drive? I know I saw 4-wheel drive during the build, but why is it acting like a 2-wheel drive in the above video?

Word by word translation or the logical translation?:lol:

Give both a shot! :rules:

JoFreak 05.16.2010 06:00 PM

Ok, you asked for it:rofl:
Word by word:
On the roll of thread:
Legendärer Faden
Dieser Faden ist gemacht aus
50% gewinnen
50% lachen aus laut
50% Legende
Das ist 150% Besitzung
Text at the bottom of the picture:
Du bist absenden in einem

As always, makes no sense at all.
Now my try on the logical translation.
Difficult since "thread, lol and ownage" are used in German language (at least the written language especially online) as well. And some words like "win" aren't usually used in that context.

On the thread roll:
Legendäres Thema
Dieses Thema besteht/wird gemacht aus:
50% Sieg/Gewinn
50% lautem Gelächter
50% Legende
Das ergibt 150% Dominanz
Text at the bottom of the picture:
Du schreibst in einem./Du beteiligst dich an einem.

Maybe one of the other German speaking people here cares to take a look at my version and has suggestions of improvement to it.
And then one of you English speaking guys reads that out loud and records it:lol:

Stumpjumper 05.18.2010 10:20 AM

Thank you JoFreak for your translation. I tryed to translate it by myself but I did´n find something expedient.

So thank you all for your positive Feedback.

Yesterday I try to make a offroad vid. But the ground was pretty heavy and after a few minutes a plastic part broke. I hate plastic stuff.
