T-maxx Custom Truggy Chassis
 

I'm going to be making my own truggy chassis for my T-maxx and would like to know if you guys have any input on which would be a preferred metal for this job. I plan on cutting the chassis much like a hellfire's chassis. 18" long with attached skids and 8" that narrows to 6" or so wide.

7475-O at .25" (6.35mm)
6061 at .125" (3.175mm), .16"(4.064mm) , .1875"(4.7625mm) and also .25"(6.35mm)
7075 at .25"(6.35mm)

Please help me on this... i'm stumped on which metal to choose from! Thank you!

6061 will be pretty easy to work with and fairly cheap. For a chassis, I'd go with the 0.16" max thickness. 1/4" is just crazy!

7075 will be harder to work with, and you won't need 1/4" - I'd say 0.125" (3.175mm).

Not sure about 7475-O

I assume the 6061 and 7075 are T6?

I would go with the 0.125" inch 7075. That alloy is MUCH stronger than 6061 so it kinda makes up for being harder to cut.

I would say go with 7075-T6. 7075-0 is soft like a butter. The "T6" indicates that it has been heat treated- meaning that its much harder and stronger. about the thickness, .125" should be good enough since that is what other major buggies and truggies are using.
Plus 7075-t6 is about twice stronger than 6061-T6.

Yes the 7075 and 6061 are T6

If you want it to be REALLY tough, get some 3mm 7075-T6. 3mm is a bit thicker than 0.125".

I think .125 is a bit thicker than 3mm. .125"=3.175mm

:rofl: I meant to say 4mm. My bad... :whistle:

Alright guys i found some 7075-T6 that is .125" thick and 24" x 12". And plan on working with that.

Another question i have is what center diff and spur should i go with if i plan on keeping maxx diffs? i think i plan on putting an axial .28 RR in the bad boy.

Thanks guys!

Given the lack of additional gear reduction from a tranny, you will need a fairly large spur and small pinion (any 6 spider center diff will be great).

Based on some rough mathes, a normal emaxx geared for 40mph uses 62/24 + the tranny; with just a center diff and the motor pinion, 52/12 gives about the same result. I would suggest using the calcultor to play aropund with your gearing options based on what a normal t-maxx would need to be geared at to achieve a certain speed....

Alright thank you. Do you know of any place i can buy the entire center diff an brake set already together other than ebay? Thanks.

i dont think you can find them as a package. i have a center diff that i want to put into a maxx, so ill be watching :D

Alright for a diff i plan on using a Hot Bodies Hardened Center Diff 50t
I'm going to cut a piece of left of 1/8" aluminum and the T-maxx tranny case to make a diff mount and top plate. And use the T-maxx Brake setup.
But my question is, which brake hex will fit around the Hotbodies diff output cup?
A or B?

the answer- C. A hot bodies brake, it will fit in the maxx pads fine.
