[QUOTE=pocket]Simply amazing now what you need to do is adapt the same 3 speed system that shumacher uses in their new 1/8th 4wd car
http://www.racing-cars.com/usa/produ...partno=prod982[/QUOTE

I live 20 minutes from the US distributer of shumacher. I just called them they only have 3 cars left & there not made anymore. It's not a true 1/8 onroad car it's a converted offroad truck.

squeeforever 04.10.2007 11:27 AM

You think you would give us any info on the system? KV, max cell count, etc?

Serum 04.10.2007 11:44 AM

Cool, welcome to the forum TeamTekin, and thanks for showing the movie. Though we guys like some technical details as well.! you can't get away with only posting a movie!! :p

Looks like a 4S setup to me.

What motor was used? a non segmented one? Feigao/wanderer/nemesis like or something completely different?

glassdoctor 04.10.2007 11:47 AM

oh crap... now teamtekin is here... he's gonna bust my chops on that other thread!! :D

Hey that Schumacher is cool....

btw, welcome teamtekin... good to have you on board!

Serum 04.10.2007 11:48 AM

Hippie; i noticed that. They do that with more 'street' vehicles. ofna/hongnor is selling an 'onroad' buggy as well.

To be honest; the street thing isn't my bag.. It moves, and it moves good.. but i am more a fan of bigger wheels, and not getting stucked onto 1" high grass.. :) I like a brushless buggy much, much more.

it's nice if you have a track, with the right tarmac..

Raydee 04.10.2007 06:49 PM

That car is exactly what I have been searching for. Good work!

teamtekin 04.10.2007 07:07 PM

The Emaxx in the video actually had an R1pro, 4slipo, stock gearing and a 2kv 36mm x 54mm motor, 6pole, 18 wind (slot), 2 turn. A proto we are working on for 1/8 scale.

The R1mt will be a beafed version to handle 30 min mains or continuous running. Honestly the R1pro looked like it was going to handle it, without a heat sink. We blew up the motor before the speedo got close to thermal. Obviously the motor design is not done yet... Might have just had a flaw in this motor. Honestly it looked like overkill although I realize that to monster guys that word does not exist. More turns would make it easier on everything in the long run. It was just a starting point and we always overshoot in the beginning.

hello:
pardon for me english, i am Spanish.

:004: this Serpent.

i want to do one, i cant to buy a second man car cheap.

questions:

* mamba max 5400kv combo + lipo 2sp 6000 mah 20C maxamps

this car run?? or is power little? and with lipo 11.1v?speed average??

Serum, can post the reference number of spur and piņion motor?

Thanks

Serum 04.13.2007 02:23 PM

Hi Lolo, Welcome to the forum!

no need to appoligies for your English, you are doing a great job.

I don't know what your goal is? what topspeed are you looking for? in other words;

what do you expect of your serpent once you converted it?

Judge 04.13.2007 02:34 PM

Hi SERUM,

I told about your project in my website here

I think your project on 1/8th car is new.

But....a friend of mine has done it (without lipos and with an IMPACT)

See THAT

Serum 04.13.2007 02:40 PM

Thanks Judge!

his conversion looks nice!! i think it will weight a bit more though. I thought about re-designing the lowerplate, but he could make that plate lighter. mine weights less than a nitro serpent (this on in nitro weights 2700 gramms dry (without fuel) (so with fuel about 2800-2850 and this one weights 2500 gramms rtr.

One thing; light is good for speedruns.

I just ran across this thread and I have to say that yours looks much better than the one I did for last years wfrccc. Unfortunately my Schulze fried on me so I didn't go. Next up in smoke was a Quark 125B and it only lasted 5 minutes. The Mamba Max I have on it now has lasted since it came out. This car consistantly makes 100+ mph passes on the Bushnell with the Neu 1512 1D in the picture that I got from Mike, and even before that with the Hacker C40 7L, it was into the 80's on 4S. Trust me when I tell you, there will be no need for any multigear setups to get up to speed. Save that crap for heavy trucks and weak motors. A motor making plenty of power doesn't have to have any "helper gears" before the main gear to have good acceleration.

glassdoctor 04.14.2007 11:58 PM

Welcome to the forum.

Nice ride... 100mph, sweet.

The Neu are nice huh? and the MM too :)

Any coggin issues with your setup... looks like you ahve 5mm or 6mm conns on the motor. I hardwired mine to help get rid of the start up cogging with the MM/Neu combo.

Serum 04.15.2007 01:37 AM

Got pics of your fried schulze?

BrianG 04.15.2007 01:44 AM

You want to add that to your collection of burnt Schulze pics Serum? :)

Serum 04.15.2007 01:46 AM

Always looking out to expand my lovely collection..

rchippie 04.15.2007 01:47 AM

Rene have you had a chance to run your car yet ?.

Serum 04.15.2007 01:57 AM

Hippie; Yes, i did.

And to be honest.. onroad isn't my bag AT ALL..

you need proper tarmac for it, we've got a new paved road in front of the house, but apparently it's too slipperey for the 30 shore rear tires.. It left some nice black marks on the road though.. :)

Like i said, you need to take her to a special club to race her, but i don't feel like investing that time.

I like a brushless converted buggy much, much better. I like vehicles that continue their way when landing in 1" high grass..

Maybe you can sell it or trade it for something you like better.

Thats to bad onroad really is'nt my bag either but i think you will feel different if you get it on a real 1/8 scale track.

Serum 04.15.2007 02:12 AM

Yeah, i thought so too.. That and grip compound would offer great help.. But it really isn't my bag. It will be fun to put on the track, no doubt..

Dafni 04.15.2007 02:15 AM

Too bad you sold your buggy... otherwise I would have tried to convince you to join me for a buggy race in Deutschland.

Edit: about your lack of grip... have you had a body on? I made the experience that those cars are like on rails! But you need the "black-groove" of a real track. If you have the chance, you have to go to one, really.

Serum 04.15.2007 02:32 AM

Yeah, i tried it with a low speed, high downforce body.

What event is where going on in Germany?

and in what timespan?

Dafni 04.15.2007 02:41 AM

Oh, there's plenty of stuff going on, starting next month or so.

captain harlock 04.15.2007 04:13 AM

How about pouring some PEPSI on the rear wheels and check out how grippy it is going to be?

Just a thought, though.

myndseye 04.15.2007 07:02 AM

No, sorry, I am not really big on taking pictures, plus I sent it back to Icare in Canada where I bought it, so they could see if it could be repaired. Two months later the word came back from Germany that it was unrepairable. It was the 18.149F and they offered me a discount on a replacement but they were only going to take $150 off, so I bought the Quark. I had cogging problems at 4S on the Mamba, but they changed from happening everytime, to sometimes, when I changed the timing to its highest settings, go figure. They completely went away when I dropped the software back down to the 1.07 version using the Castlelink. I make about 5 passes before I bring it in, because I don't like to let the heat build up. Let her cool down and go out for another session. The Castle hasn't even thermaled yet. I am patiently waiting for the Monster Max to come out, to better handle the load. Yes it has the 5mm plugs all the way around, and wet noodle everywhere else. No changes to the Mamba, even though I usually wet noodle the mains on that controller. I will try to get video today if the weather holds, if not, it will be the first dry day that comes.

myndseye 04.15.2007 07:07 AM

By the way, check out where we run. This is a link to the Windows Live map thing. Be sure to hit the button to switch it to the birds eye view. This road is wide, smooth, has low interference and traffic, and best of all, is a 1/2 mile long.

Serum.........if you tire of your Serpent I'll buy it or trade you something for it. I do heli's, off-road, Airsoft, Astronomy, exotic cars, you name it, I probably do it for fun.

fyi.......I used to race 1/8 scale with one of the top drivers in the world (Ralph Burch). I had a lot of fun but I got out of it due to my dislike of gas power. A brushless setup like yours would get me back in the drivers stand.

I want that car and one like it.

Serum 05.20.2007 03:12 PM

Thanks Aerangis;

Maybe Mike will be offering a conversion for the 960, but he is very busy at this moment.

are you currently running a brushless setup? i remember you posting about a brushless revo, considering buying one?

captain harlock 05.20.2007 04:49 PM

You're selling your revo, too?!!!

I really wished I was the one to get your 950 at the time, though. I'm broke now.....:(

Sylvester 05.20.2007 05:04 PM

What revo you selling Rene? How much? PM please :)

Serum 05.20.2007 05:22 PM

No man! that's not what i meant.. :)
I meant that he was looking for a brushless setup for his revo; he asked questions about it; that's the reason why i asked if he was looking for a brushless setup for his revo. I read the post, and understand how it got messed up though.. :p

aerangis 05.21.2007 08:19 AM

Yep, I bought a revo roller with the intention of converting it to BL. I bought the rc-monster BL motor mount that works with the stock mount along with a UBEC (fast shipping btw) and plan on doing the conversion as soon as I can get a grip on what motor/ESC combo to use. I want to use the stock tranny and gearing if possible. If not, I need some direction on a good setup. Back in the day when the choice of brushless motors was pretty sparse (Hacker, Lehner) it was easy to make make choice. Now there's so many motors available it makes it much more time consuming to research the available options. Any suggestions for something inexpensive and bomb-proof?

It was just a feew years ago when I used to catch a lot of crap from the gas guys about for running BR/BL setups in my boats. Now you see more guys running electrics than anything else. And the electrics are more reliable and faster.

Brushless Vector........damn........I've been tinkering the with the thought of an electric Vector for the last few years. With the advances in BL technology and wealth of interest in electric power, someone is gonna make a conversion kit.

I want one so bad I'd let you borrow my Gallardo if you'd sell it to me : )

RaceBucks! 05.22.2007 09:40 AM

Hey!!!!
 
This is very innovative! very nicely done. I would like to ask if you have a number of upper decks available? I would like to get one along with the battery and motor mount.....
