Project: Honey, I Shrunk The E-Maxx

[halesk]

nice stuff !!! i love it

[SnoopMaxx]

I see the video in the web page and The link you posted now. I still wonder what one of them,machines run.............. it would be nice to own one and yes I'd have to go take some schooling if I did ever acquire one. Just think about all the rc stuff I could do not counting possibly making some guns and a ton of accessories for Rc's and guns as well.................

dtnel I'm a machinist by trade
I used to play with machines like that

I make most of my parts with hand tools, drill press and a lathe
Can you see what this is ?


daniel I can't wait to see that chassis running

Nice Chassis's. How much in american dollars did that cost you to get made if you don't mind me asking. That'll be a sweet ride when your done as all of yours are...............

Thanks! The aluminum sheet was like $10 and the CNC guy charged me like $50 to do all the work... He also included the silver anodize process for free when everything is tested and ready to run.

Now, I'm missing both battery trays which should be ready next week, and the chassis braces... Hope I can finish it before the end of the year...

[danielhr77]

Yup, yesterday, when I paid him, he told me he overcharged me and wanted like $40 for it... I told him that we already settled the price for it, so, he gave me a discount on the other parts... He lives here, in Argentina, this is his webpage: http://www.3drcmodel.com.ar/

[danielhr77]

Hey Guys,

A little update, today, I got the battery trays...



And, take a closer at them...



Cool, right??? I'm designing the chassis braces right now, they will be ready soon..

Hope you like it so far...

Daniel.

[dave00bear]

Very nice Daniel!
This is a one of a kind build thats for sure. Lookin awesome!

[chevyman08]

this is a pretty sweet little project!!

[slash116vxl]

Any updates?? This is awesome, but old.

[danielhr77]

I'm afraid not, the CNC guy put me on hold because he's extremely busy, I'm only missing the two chassis braces to finish it... Hope to finish it soon, maybe by the end of July...

This is the first time I've seen your project, and I must say I'm impressed with your efforts! I'm excited to see the finished project, and now am wishing I'd bought myself a mini mill setup instead of my emaxx.

[halberd1995]

You should aluminum everything so the car is durable. You should put in a dual velineon system for a lot of power in that little thing. You'll have to show us the end result.

[Phase V]

You could make a ton of money selling the idea to Traxxas. 1/16 emaxx would be the rival to the mini revo

Hahaha... But, this is not a 1/16, it's more like the Stampede 4x4...

I'm not really a basher, I do speed runs mainly, so it's not necessary for me to make it bullet proof... Also, take into account that 1 Velineon is moving a complete E-Maxx transmission and it needs to be light...

About the Twin Velineon, I already have a V-Twin E-Maxx and I just finished the same chassis like this one but bigger...

We're gonna need some pictures of that...

[danielhr77]

I'm not happy with the way it turned out, some holes (2 rectangles and 6 triangles) at the front and right side were not finished by the machine and I don't like to hand finish it, so I will release a new version with a few improvements as soon as the CNC guy can spare some time for me...

[slash116vxl]

So you're running a single Velineon setup? That's it? At least put an SCT 3800 in there.

[danielhr77]

Not need to, most of my custom projects are almost Shelf Queens, will be run once or twice in their life...

[Thomas P]

Real nice work, sad that i have missed this thread..now im hitting F5 every morning ...keep the pics coming mate =)

[KingJerd]

Why not use the 1/16 Revo knuckles?

[ArmyofDarkness]

Because they wouldn't fit the a-arms and driveshafts he wants to use ( using the 1/10 components but shrinking the proportions to ~1/16 scale essentially ).

[ToXiC MeRv]

the chassis is still just as long as the original emaxx chassis, i thought it was gonne be smaller?

It is smaller!



Mini-Maxx on the left, stock T-Maxx chassis on the center, V-Twin on the right...

They say bigger is better. If I had the time & know how, have to build a 1/5 Maxx.

[ArmyofDarkness]

Less of a challenge though- '1/5 scale' emaxx is just a case of stretching the stock chassis ( cut & paste basically ) and running some silly axle extensions with giant tyres; it isn't true 1/5 scale as all the components are the same. Look at a 1/5 FG Marder, a Baja 5b/t , or a Redcat, then compare the size of the suspension components and diffs to that of a normal emaxx, savage or 1/8 truggy; size doesn't mean alot if the strength of the parts doesn't increase too, but anyway.

I like the mini emaxx project, it's alot of fun and building something truly unique- the size doesn't matter so much, more the complexity & originality of the design & the execution.

[danielhr77]

They say bigger is better. If I had the time & know how, have to build a 1/5 Maxx.

It's under construction too... But, 1/6 scale, 18 inches wheelbase... Redcat body with Jumbo kongs... RPM parts with 16mm big bore shocks... Yeah, I have too many projects going on...

Btw, tomorrow I'm sending the chassis and the battery trays to anodize in silver, so, when they are back I can build it and test it lighly until I have the chassis braces...

[87 GN]

^True But I am not talking just extending the chassis. I am thinking true 1/5 scale components.
Have any pic 1/6

[ArmyofDarkness]

^True But I am not talking just extending the chassis. I am thinking true 1/5 scale components.

There are no 1/5 scale components to use- you'd have to design & manufacture your own which would cost either thousands ( for alloy parts ) or hundreds of thousands ( to make the molds for plastic parts ); using chassis, driveline & suspension parts from other 1/5 scale trucks and mashing them together onto an 'emaxx style' 1/5 truck would result in a monstrosity

Easier just to buy a redcat, marder or something similar and convert it to electric = instant electric 4x4 1/5 scale MT.

[87 GN]

Ok thanks, I just keep holding out for a 1/5 Maxx or Revo

77 who is doing your machining??

[ToXiC MeRv]

oh, i thought that this was the mini maxx chassis since you posted a picture of it

Read the words which go with that picture- post 94 & 95

[danielhr77]

77 who is doing your machining??

A local guy here that has the CNC machine at his home... It's not a professional machine but it's not a hobby machine, something in the middle that works quite well for 7075 aluminum... But, he's extremely busy lately and keeps putting me on hold...

[danielhr77]

Got tired of waiting for the CNC guy, so, I just bought a CNC machine...



I'll have to learn some new 3D stuff but will be fun...

So, I'll post pictures as soon as I got it and hopefully I can finish all my custom projects before the end of the year... And, create some more...

[ToXiC MeRv]

how much was that cnc machine? and it looks like your gonna have to move the chassis and parts around as you go

[danielhr77]

$715 plus shipping (= $880 total + local taxes = $1200)... I'm planning to enlarge the table before using it, so, size won't be a problem...

[genXrated]

Nice! So you hook up to your pc for programming and display with that?

[SnoopMaxx]

$1200
I'll just settle for my manual 2 axis table for my drill press

[danielhr77]

Well, got the chassis and battery trays anodized in silver...




And, extras, steering posts and motor mount...



They are a little out of focus, it's almost 4am and dead tired...

[reod12x2]

so what dose it look like now?

[danielhr77]

There's nothing new so far, I got the CNC machine last week and I'm still trying to understand how it works... The only thing left to do on this projects are both chassis braces... That will be the first thing I'll make...

[hurley747]

It probably uses gcode if it is a "hobby one" not sure though

on the other hand-thanks for answering all my question and maybe this will help you with your router:

http://www.machsupport.com/

Here is some good software for your CnC machine (its controller software) that downloads with a DXF importer(lazycam... you might need to get it separatley)

using google sketch up to design parts (free version)- download CADSPan to create a gapless model once your done

http://www.cadspan.com/software

you will have to make an account to use it, but its free

http://www.guitar-list.com/download-...les-dxf-or-stl

use this google sketch up plugin (ruby code) to export the gapless model to a DXF file that your personal CNC router(more importantly: Mach3Pro) can use

and MAch3 Pro can use the DXF file and turn it into Gcode for your CNC to use

and im not sure how your CNC router is hooked up but most Hobby/personal/DIYs use a "printer cord" AKA parrallel connector... outdated but it works and is cheap


considereing your a VoIp engineer
wasnt sure if you new this and i dont think you have access to "the good CAD programs"(these make the process fool proof and will work 100%- but only if your willing to drop 495 USD for google sketchup PRO)
any questions on that let me know

Now all you need is a 3D printer to print small parts in ABS plastic and your set..haha
