    My 10x10 E-Maxx with x4 steering

    Hey Guys,

    I've been working on this project for some time now, knowing it will take some time to complete, like all my other projects, but I thought I would share it with you guys anyways...

    So, as the title says, I'm building a 10x10 brushless E-Maxx with steering on the 4 front wheels...

    The lower chassis is going to be made from a long 4mm aluminum sheet... Total lenght 47 inches...



    Is curently at the CNC shop and hopefully will be ready this week... As you can see it has the space for 5 bulkheads which I got from New Era Models and modified 3 to accept a chassis on both sides...



    About the differentials, I needed five, 2 stock and 3 custom, so, I got 3 custom made alumium dual diff cases...





    They came from France (not cheap) made by a forum member, but I haven't heard from him in a long time now... And, this is how it looks assembled...



    My idea is to use a cheap brushless combo as I'm not going to run this truck more than a few times and I didn't want to use a Titan 775 on it... I will use four 2070 servos and with a little luck it will be finished soon...

    I have all the parts ready to assemble it, but before that I need to send the 5 upper chassis to the CNC shop, but before doing that, I need to assemble the bulkheads on the chassis and meassure the exact length for each of them...

    About chassis braces, I drew the holes for them on the lower and upper chassis but I won't make them, at least for now, I'll see how it handles and how much the hole truck flexes without them... Probably I will end up making them, but that's the last step...

    Well, nothing else from now, crazy project right? I haven't seen a 10x10 E-Maxx before with this length and hopefuly will be fun to watch and run... I'm very curious about the turning radius without rear steering...

    Hope you like the idea, subscribe and enjoy it!

    I recently finished a 6x6 T Maxx with rear steer and love it. 10x10 would be amazing. Those diff cases are awesome (I had to use the Revo diffs). What tires are you running? Are you worried about shredding the center diff?

    I started a 6x6 two years ago but never finished it, I have another dual diff case for that project... Might finish it next year...

    Thanks! I bought four of those diff cases, I paid like $80 each set...

    I'm not planning to bash it, it's just to show off on asphalt at low speed... It's something I wanted to try for a long time...

    Body... Haven't seen anything that might fit 47 inches... I'm open to ideas...

    several bodies fabricated to look like a moon rover....will it be a solid chassis or will it have knuckles that allow it to bent and twist?

    you could do a unimog front with a flat bed or a box to cover the shock towers and wires

    What are you doing to reverse rotation of the output of a middle differential before it goes into the next diff?
    I could be mistaken; but I think if the input of a middle diff is spinning clockwise, the output would be spinning counter clockwise.
    Whatever it is I just said... I could be wrong.

    Flip the diff and the rotation is reversed. You flip the diffs to get the correct rotation. On my 6x6 the first ring gear is on the right 2nd=left 3rd=right. I believe on a 10x10 like this it would be 1st=left 2nd=right 3rd=left 4th=right 5th=left (assuming the transmission output rotation direction is the same as a T Maxx).

    would it be possible for you to comment with the name of the forum member from France that fabricated these double sided diffs? i wanna build a 6x6 e revo.... if you cant list please pm me the name....

    Anyways, why a 10x10? instead of something like a 8x8 or something along the lines of that? and for body, i vote a semi with a car trailer, that way you can haul all your other rc's...hehehe- subscribed!

    Here you go: http://traxxas.com/forums/showthread...678-T-Maxx-6x6

    But, you don't need these diff cases for an E-Revo, just join two output sides of the stock diff cases...

    Mainly because I haven't seen it before... I've seen 4x4, 6x6, 8x8 but never a 10x10... And nothing 47 inches long... And, I might add a trailer to it too...

    Well, the chassis was ready today but the shop had a broken printer and couldn't print the invoice, and it's not near by, so I decided to go next Monday. It's going to be a long weekend!

    can't wait to see this build go through, from reading this thread i came up with an idea to make a 4x6 slash! make a custom mount to attatch another rearend to the rearend already existing on the car. and with the 2 2x4 rear ends you wouldnt have to make a custom double sided differential case, you could put paddles all the way arround on the rear two axles, and the skis for the front, that thing would be terriffic in snow!

    P.S. thanks for the link

    Lower chassis is at home!



    I have to work a little on the edges, drill a few holes and start working on the upper chassis...

    I wanted to make it more like a real truck where the front 4 tires turn and the rear 6 tires are locked...

    its going to be sweet what tires are you going to be running. I expect some lighter tires, with big joes it would be like 30lbs

    Thanks! Stock E-Maxx tires with 14mm hex... I got them cheap sometime ago from a seller that had too many in stock... And, you know, the inside of the rim came in white and black, so, I have a mixed set...

    im certainly tuned in on the project, i keep getting goosebumps when i see all the parts for the build... wish the machine shop here didn't over charge and take too long to fabricate parts... otherwise i would do a out of the box project like this, i see another project like this coming to mind... but still with the foundation of the 4x6, fabricate the same adapter in this kit: http://www.ebay.com/itm/Aluminum-Dua...item2ec46a87aa and install it on the rear two axles, then install a new bright semi body- so you would have, a semi! not trying to hijack your thread, i deeply apologize if it is coming off that way

    No problem... I just wanted to have the longest E-Maxx ever built so far, and I haven't seen any with 10 wheels... It's just for fun... Not trying to make it perfect or super nice, just trying to make it work right now...

    Thanks! Wish I could have too much time! But I don't, that's why all my projects take so long (this one is more than a year old since I started working on it). Well, have some bad news, the guy from the CNC shop used an older version of my drawing that I sent a few months ago when I was talking to them for the first time about making the chassis and the 4 holes to mount each bulkhead don't align quite well. My updated version fixed that problem. They offered me to make it again for free but I don't have aluminum to send it to them, so, now I have to go and buy an aluminum sheet, send it to them again and hopefully this time it will be perfect. So, I'll have to wait like two more weeks to continue working, the Holidays don't help much.

    They told me they will make it again and will give me a discount on the top four chassis... They don't sell aluminum, they are just a CNC shop and I had to buy more anyways for other projects...
