Nitro Stalker Duel Brushless

[DOOBEEWHA]

In the not to distant past..

I was really not in to nitro like I am now. It's not that I didn't like Nitro, persay...

It was more like...
Did I want to dive into a commitment and have to make the effort of learnning the whole nitro thing?..
Or at least, as much as I would hope to learn from it?....

At that time....That answer was NO.

But I did want a truck that was able to stand up to any other truck in it's scale. Like with something under
the hood.

After overhearing a conversation at Jake's proformance hobbies, a LHS in my neck of the woods,...
I was stunned to hear this comment....

"Yeah..Well I'lll tell you what,... That damn truck,... It pulled a wheelie at forty miles per hour... It wassss amaz'in".

Well,... I had to ask.. What the heck were you guys talk'in about?...

And this,.. is what they told me....

"It was an E-MAXX, that has the right to live."
AAAAAAAAAAAAAAAAAAAAAUGH!!!!! screamed a customer from the Savage parts section in the LHS.

And they wern't talk'in bout no out of the box model... They were talk'in bout....

=====================================THIS ONE !!!======================================

Say hello to my little friend.... =========== E-MAXXIUM ===========

The Dodge Charger Body was just too hard to resist for this NHRA Pro Modified Class Theme.

At the time I painted the Body, I didn't know how to paint chrome on the blower. Silver will have to do.

A closer look at the decal work shows that the decals were overlapped to get a custom fit
and appearance.

There's no question that the MGT tires and rims make this little commander of kaos get
some elevation from the normal ride height. This pic should give you guys a clue of what's
under the hood.

In case you didn't notice, This little guy can sport up to an uncontrolable 33.6 VOLTS if you found that it was
absolutely nessessary..INSANE.... Not to metion, DANGEROUS. Caution is advised when running this truck at
half that VOLTAGE.

Again.... those wheels....

And again with the clues...

I believe that in the gallery, clicking on the pics will enlarge them.

As you can see, the decal work had to be a labor of love.

Ok, Boys... WHAT'S UNDER THE HOOD??

that truck looks bad doobee, what else is lurking in your bag of toys?
dual brushless are you kidding! what is that like?
I don't evan care its a traxxas

 

[DOOBEEWHA]

Hey crash..
Right when I finally completed this build, I meet savagecre.

I had my 4.6 SS kit still in the box.
I found out he had a savage also, so I jumped in to that build and had it done in a few days.
Nitro had entered the scene as I broke in the savage with my buds oversight.

Haven't looked back.
This truck is has not seen the road yet.

 

[Crash]

wow , box it up . you have my address bud........................

 

[Savage89]

Looks sick. I'm thinking of maybe something electric or even taking my stock savy parts and maybe building another one

 

[DOOBEEWHA]

Here's some under exposed pics of the front and rear shock towers that show close ups of the ESC with
fan setup. There's a heat sink located under each fan whick draws power from the ESC itself. This helps
in keeping the ESC cool as the high amount of current is regulated through the circiutry.
Front...

And Rear.

I went with Integy on Skid Plates, Bulkheads, Front and Rear. And of course, the shocks.

The stock shocks could not be trusted to withstand the demands of the extra wieght that
will be placed on this trucks chassis. These Integy shocks are beefier than thier first version
of T-MAXX shocks, they sold. They are highly reccommended for this application.

The GORILLA MAXX ALOY CONVERSION KIT was the way I was advised to go if I wanted to carry
the full load of battery capacity. 28 "C" cells at 1.2 volts each. Take four of your roto start batteries
and then add four more cells. Thats what this little guy can carry. And the run time.... 40-60 mins.
Thats depending on how hard you drive. INSANE.

This chassis conversion kit was absoluely nessessary to handle the massive torque that just one brushless
can put out on the chassis. I spent a little time at the buffing wheel on the lower deck. The tranny also
sports an all Robinson Racing conversion gear setup w/ Idleler gear.(Steel)

Here, you can see the upper decks alloy servo mounts and MIP dog bones... The truck has an all MIP drivetrain
from the tranny, out. All done in MIP Outdrives, diff cups, drive shafts, front and rear, Axils, ect. Basically, a full
metal drivetrain...... Not your E Maxx out of the box.

 

[Crash]

man you been holdn out on us. that thing is sweet.

 

[DOOBEEWHA]

wow , box it up . you have my address bud........................

Think of some numbers, crash. It just might be yours.

 

[Crash]

heres what it might run like

Doobeewha: OK... that pays for the antenna tube....

 

[Crash]

I'm not gonna even pretend that I could afford that truck.
Its way to sweet, you saw my rigs.
you should charge her up and test run it. shoot video for us.

 

[DOOBEEWHA]

Alright.. HERE'S THE BEEF...

Duel HV 4400 NOVAK BRUSHLESS MOTORS WITH FAN COOLED ESC's
Able to deliver 16.8 VOLTS x 2 Total combined MAX Capacity: 33.6 VOLTS.

Here's a great angle to see what's on board this truck. The ESC's (electronic speed controlers)
have capacitors thar are attatched, externally. This allows for the ESC's to run much cooler
than earlier versions of ESC's.
Cooler temps = Higher speeds and proformance. The caps are zip-tied against rubber padding
at the base of each bulkhead.
You also need to picture this truck carrying up to Twentyeight "C" cells at full capacity. That's
Fourteen cells, per side. LiPo's are a disirable option here. Their much lighter than
say, NiMH batteries.

The tranny, upper and lower A-arms, wheel carriers, hubs, front and rear diffs, and
shock towers are what's left of the original parts for this truck.

The wiring on this build was the most creative element in this assembly process. It
posed numerous chalenges in these tight areas of access for a propper wire routing.

The NOVAK 4400's come shipped with massive heat-sink's and Noodle 8 gauge Wire for the ESC and brushless motors.
The wire itself is jacketed with silicon and contains 100's of strands of thin copper wire for flexabillity and continuity.

And finally, This vantage point shows the upper and lower decks of the GORILLA MAXX chassis system.
The upper deck supports the ESC's and servo's at the same time as it attatches to the central chassis supports.
The lower deck creates the ridgidity of this five piece chassis system. Double sided adhiesive foam was used to make
a good fastenning tool in the case of seccuring the wiring harnnesses to the chassis.

WOW NICE !!!!! I come w/ questions .. how much does it weigh ... and do you have videos? and w/ something like that why NITRO !!!

 

[DOOBEEWHA]

This is a cool vid, Crash.
I do suspect that the guy that was running the truck had a limited amout of voltage on board...
There's also options on how you may wire the ESC's and get a different input/out voltage.

It gets a little complicated, but easy enough to setup, once you've read the documentation abit.

The truck I've built here has a more radical wiring layout.
But it still manages to be in the relm of warranty and propper use guidelines.

WOW NICE !!!!! I come w/ questions .. how much does it wiegh ... and do you have videos? and w/ something like that why NITRO !!!

Hey, SJ. Thats a good question...

I've never actually wieghed the truck yet. I can say that it's within oz.'s of the savage I have.
The Savage is using the MSR-6's. So that makes the Savage abit heavier.

Here's a pic.

With the Duel E-Maxxium, The batteries will throw it way over the top and out wiegh the Savage.

Sorry,.. No vids at this time, But I do have a camera, so that may change here, pretty quick.


Why Nitro,... you ask? Well,... I said that very same thing.

Before these trucks came into my life, the only experience that I had with glow engines was the
little .049 engines that were in the COX Branded cars and U-Filte planes, "back in the day".

I was between the ages of 9 -14.

My God father saw that I had an interrest and desided to give me his collection of model plane stuff
he had stashed away for years since he was a kid.
Amongst other engines, there was this Red headded .35 Mc Coy Plane engine in pretty good shape...

"WOW!!" I said to myself.


Anyway,.. Long story short,

I spent weeks, using up all my free time, building this balsa wood Plane kit.
I got the thing running and ready to go.

On my maiden flite,.. before I could even complete the first revolution of flite,...The bell crack that
steers the plane, locked up and my plane power dived staight into the ground.

DOEUGH!!!!!!!!!!!!!!!!!!!!!

At that point,... I was way too ticked-off.
All my time and energy was spent, building and prepping this plane.
Only to find that it came down to this...
I couldn't entertain the the idea of affording this hobby of an RC.

So... I basically walked away from my childhood pass time for years and focused more on other interrests
like Guitar, Girls, Part time job, full time job, Audio Electronics Repair, HVAC, ect.

Having crashed the plane was one thing, but walking away from it never really sat well with me.
So... with the trucks and planes that I enjoy today,...

I've come to the conclusion that I like Both. NITRO and ELECTRIC.

Yea... I could do that... But wouldn't you like to have the honnors yourself?
If I pop her now... She won't be a virgin.lol

 

[DOOBEEWHA]

lets add a brushless e savage to this thread.
http://www.youtube.com/watch?v=wEK5gN3P0qU

Thanks, Crash.. Thats a cool touch. In fact, we might consider a additional section for this If we had a vote. I suggest starting a new thread, Dan.

There,... You can put it to a vote. Locate this thread in the suggestions section of the forum.

 

[Crash]

what are we voteing on?

 

[DOOBEEWHA]

SPECS: HV4400 Brushless Motor Specs:
Length: 2.84" (72.1mm)
Diameter: 1.41" (35.8mm)
Weight: Motor: 8.36oz (295g) Heat Sink: 1.97oz (69.5g)

Kt: 0.76 oz-in/amp
Power Output: 375 watts @ 14.4V
Commutation: Sensor based electronic
Magnet: 1-piece, multi-pole neodymium
Performance: Approx. 20% longer run-times (capable of between
32-38 MPH in a basic E-Maxx setup with improved drivetrain parts)

thats only with one of these motors, imagine two.

Again, Very helpful, Dan.
Thanks, bud.

Now take these specs. and add an additional HV4400.

You will be able to see the unbelievable torque that lies waiting at the power plants.
It is also believed that the 4400's ESC can easily handle 2 more "C" cells.

This will bump up the voltage to a sizable 16.8 volts while rounding off a wattage to over 400 watts per brushless.

With a total voltage of 16.8 V. per side.

 

[Jeremy]

I seen a brushless savage (somewhere ) he was pulling 65 on the radar gun what gearing are you running ?

 

[DOOBEEWHA]

what are we voteing on?

I'm sorry,.. I wasn't clear.
We would be voting on having a section for:
"E-SAVAGE/E MODS/Other Electic Trucks" section in the forum.

This is just an example.

 

[DOOBEEWHA]

I seen a brushless savage (somewhere ) he was pulling 65 on the radar gun what gearing are you running ?

After some discussion of what gearing to run, I went with
the same tooth count as the stock greaing except it's now
Robinson Racing Steel gears.

It's been a while since I looked to see the T count.
The tranny is set up to be completely sealed to the elements.

There's so many ways one could go with gearing setups ,
it's crazy. Some setups completely illiminate the tranny, all together.

The torque dilivery is different in the rpm ranges, compared
to nitro.

To be honnest, I need to brush up again since I've been away
from it for so long..

 

[DOOBEEWHA]

Looks sick. I'm thinking of maybe something electric or even taking my stock savy parts and maybe building another one

Thanks 89.
SORRY FOR THE LATE RESPONSE.
Let me know if you need E-Maxxx engines, ESC's tub chassis, ect.

 

[lifter37]

looks to me like its got a 426 hemi punched, full roller and a 14/71 blower.

 

[Crash]

good call lifter.

 

[DOOBEEWHA]

looks to me like its got a 426 hemi punched, full roller and a 14/71 blower.

I really wanted chrome on that scoop.lol

 

[Crash]

thats one sick rig

got any pics of it?

all the pics are lost in cyber space
