So with some Goo off orange gel, simple green, rag and a razor knife I cleaned up most of the body. the front has a few holes and a lot of glue holding the other half on so I will remmend it , paint it and hide some of the holes with a Scale look grill mesh
So it's pretty clean now , guess I should have taken a before pic, oh well.

Body front after clean up

Motor and Idler just arrived today
Wow this motor is huge and heavy

Really need tires
anyone have ideas & link for 4" to 5" tires that would fit the old Emaxx 3.2 (3 1/8" rims) or any 1/8 buggy wheels

Thanks

Try a set of 2.8 Losi speed T tires on the stock traxxas e/t maxx wheels.
maxx wheels are 3.3. A guy came in the local Hobbytown and put a set of
stock maxx wheels with the speed T street tires on his slayer.
looked like it had a set of 28 dub wheels on it with low profile tires.
tires can be stretched on but takes a little work.

Does it stand on its own now?

Hey guys, sorry it's been a long time
but IT RUNS !

I found a cool set of tires on ebay (Sportwerks hot laps Auto cross) In my Effort to support my Local Hobby Shop I drove there to order them, I asked them to order them early December. The shop forgot the order did not get them till late January Again I found cool wheels on ebay and asked the shop to find me some . The hobby shop only carried bright yellow and white 1/8 scale wheels and could not find the black spoked. The Owner gave a Rude comment that I cant be pleased. Instead of him telling me that I should go to his other Shop 20 minutes away which has a HUGE variety of wheels and I should look there. Well I went and Found Exactly the wheels I have been wanting at his Other shop, what a jerk With that poor service I would have saved a lot of gas and time and a few bucks cheaper buying them on Ebay instead.

I dont have the money right now for big 6S Lipo batteries to run the huge Brushless 2100k motor so I dropped in the fastest brushed motor I had 10x1 and 7 cells nimh. The car only goes about 25mph. but was cool to see the big thing go.
It had heavy body roll without the sway bar so I added it back in and made a huge improvement.

It was very cool to drive and cant wait to drop in a Thunder power Extreme 22.1 volt Lipo 5000 . I have seen on youtube a Revo go 61mph with on board GPS. So getting this beast to 50 shouldn't be a problem with a upgraded drivetrain.


The shock towers will be made and Drilled so that when going Offroad and jumping All I have to change is the 4 nuts for the upper shock placement.
Still needs some shock and spring tweaking .

HELP Please . Need help on PAINT I want to remove some of the Yellow around the grill area and continue the Red from the Flames to the lower valence.
Can a Paint pro or somebody tell me the safe way to remove the paint

I'll shoot some video and post it
I thought I had Street pics, guess not
Thanks

I was wondering what happened to this...thought maybe you gave up.


Or it ran you over.


Good to see it up and running though!

[toy4crawlin]

I'm back

I dropped in my Mamba max and 12 cells !
I'd say it maybe goes 22 mph with locked 4wd


so Shopping for a ESC
Mamba monster = only 6s lipo , possible 50 mph with Two 3s lipo 5000
MGM = 10 S lipo max , speeds over 70 mph maybe 80+


Car Weight
7.5 lbs
with Motor no battery 9 lbs
Loaded with 12 Nimh cells 12 lbs


Work To Do:
Motor needs to be lowered onto chassis
Bigger Shocks
Neu motor, not sure which one, maybe 1515
Needs Front Differential or a Xray Trans diff

ESC options:
MMonster
or

MGM 9032 Car/Boat controller 90 Amp

Latest Firmware installed! Future updates via computer download. New "traditional" style construction with dual heatsinks! Perhaps the ultimate "big truck" brushless controller! Dual Heatsinks, direct soldered battery and motor leads, 150000 rpm capability( with 2 pole motors), a 90amp capability with up to 32 cells or 10s LIPO packs!Programmable Lipo voltage cutoff, small size. This is among the best controllers available for high voltage brushless applications!

other high power ESC's 100-250 amp

Something you might want to consider, and an issue I had with my Revo to Slayer conversion, is transmission gearing.

Since the tire radius dropped considerably, I had tons of torque but not alot of top speed. I could either swap out the primary gears, or go with a whole new transmission.

Gears were $10, the whole trans was $35. I went with a trans.

Speed is now back to a respectable level, with enough torque to still allow it to launch on its bumper.

Yea I need to re gear, it Peels all 4 on acceleration.
but with 5mm motor shaft I have limited gear options.

I am aiming for a Xray center diff tranny--> direct drive.

It's all about money and time and I lost my $70k job this will take a long time.

Plans are
6S to 10S lipo
Nue 1512 Brushless or similar
Tekin XC8 or MMM or MGM ESC
CF chassis
Xray or OFNA Drivetrain

[toy4crawlin]

Super Torque ! Wheel spin launches :-P

I did some gear changing
21 pinion 58 Spur
3s 2250 30C lipo 28mph !

I'm, thinking of going 48 Spur
All 4 wheels spin and even at 10 mph it launches
All this on old rough Asphalt


Cant wait for 6S or 8S Lipo

[toy4crawlin]

Been busy on ebay selling off my RC stuff and anything I could find to fund this CAR

Ok some new parts arrived :-P

Losi aftershock 1/8 Diff centers
Losi HD Diff housings

Losi 2.0 truggy 16mm shocks

FG wheels in the mail from United Kingdom
machine up some adapters

Ordering two Neuenergy 5s1p 3200 25c lipo's = 5s 160 amps 6400 mah $150.
Speeds expected in the 55+mph !

Ordering Mamba Monster and CC 2200 motor


Emaxx diff bulks/suspension cage can be modified to fit the Losi 1/8 aftershock diff centers. Since the Emaxx t-maxx revo diffs are very weak.

Been getting on my info on RC-monster.com

pics not fitting, have to edit

[jeepcreep]

great to see you working on this project again.
have you tried fine design rc or kershaw designs for your pinions, from what ive seen they have a pretty good selection for 5mm.
be sure to get some vid when you have the time.

[theslowguy]

Where did you get those lipos from? Its always good to know where you can get a giant brick of tire ripping power for cheap.

[toy4crawlin]

UPDATES !

New shocks ! All new drivetrain !

Machined some delrin and aluminum blocks for the diffs to lock them up
machined some adaptor rings to use losi centers with emaxx bulk heads

cut/ modified traxxas stub axles to use as diff outputs for the losi diff to connect to revo shafts, last pic

LOSI 8ight, Diffs and LOSI 8 E Center 49/14
total ratio to start with 11:1

Original emaxx tranny ratio was 15:1 and with 3s lipo and cheapo Feigao8xl 2183kv motor the wheels peeled out . it was a blast to drive

[toy4crawlin]

NEw used FG 1/5 wheels
been a machining nightmare making bolt adaptors to get these on, so no luck yet.

made a new tranny/motor mount out of delrin, just need to square up/ drill and bolt it up

new Castle monster combo 2200motor
programmed my old faithful Airtronics radio (with the BRAKE BUTTON ! )

Working with my mamba max the brake was awesome, a castle tech help me program it but for some reason when I got my Monster I could not get it working on brake button so I called castle again and only got a ignorant guy telling me there system is not design for brake and the button is a " back button"
after trying to tell him numerous times it works on my max and him still not acknowledging it I gave up and just tweaked on it for a while my self and got it working

Been shopping for a 5s or 6s lipo and found a shortly used 6s Polyquest enerand cells 6000mah 25c for only $150. from Australia and so excited to get it I just found out the guy cant ship because of new mail restrictions, big fat bummer
Any body got a nice lipo for sale ?

Speeds will be in 50-65mph !

the lipos were on a clearance sale but they went so fast that they only had one left
so I'm still looking for a 5s or 6s setup

where are all the good places to shop for Lipo's ( with Enerland cells) ?

[NeXt559]

yeah!!! finally an update!!!

this is the first time i have ever thought the mamba monster max and neu motor looked small

[toy4crawlin]

LOL
Yea no kidding, hrd to see the motor is 3" long !

[toy4crawlin]

Goodbie Crap Green !
I picked up some high heat engine paint (500*) but the yellow was super light so I used regular Enamel that withstands 200 degrees

I masked off the fins so I wouldn't have the tedious task of taking the paint off but I ran out of tape half way. painted it then used razor blade to crap off the fins that were painted

came out really nice

[d-fly]

go to hobbycity.com and buy batterys from them. I would suggest a 5 or 6 cell 5000mah flightmax.

http://www.hobbycity.com/hobbycity/s...idProduct=8590

thats the 6 cell

http://www.hobbycity.com/hobbycity/s...idProduct=8589

thats the 5 cell. I have that and i am going to use it in my truggy conversion with a mmm 2200.

cool, I'm not sure about zippy, only $100. they claim 30c but I dont know for sure.
you get what you pay for .
Any idea what cells are used in those packs ?

I'll do some searching and see how people are liking them.

I'm looking for Enerland cells, Flight power, and I think Thunder power using them, best stuff and will last.

[d-fly]

I have the 5 cell version 30c and my freind has 4 of the 3 cell versions. He thinks they are the best lipos he has ever used. They also have a warranty on them. Also they sell a 1/5 and 1/8 esc. I dont know much about it but its only 150$. worth a try. The thunderpower and those brands will cost 350$ for the same 5000mah battery. It is worth trying this. you can get three for less. I liked mine atleast.
