2nd Version "MaxxEXT 2.0"

here's another version

i make a 3D e-revo transmission dummy to have a impression how it will fit between my Chassisbrace

and with two little parts it will fit

Yep, FLM/ RC-M actually had a similar product for sale briefly that alowed you to mount the 3905 style tranny on the 3906 style chassis- discontinued now as FLM sell a dedicated 3905 chassis, but a few people have made their own basic version too.

yes, but the flm 3905 chassis design is with a plate on top of the brace or not?

my chassis design is with a plate under the brace and it handle the 3906, 3905 transmission and a centerdiff with a lower CG

i think it's time to redesign it again, in a length to use a aftermarket centerdriveline and to go with alternative body's

the mammuth body i use is to short and i can't find other's with a 425mm wheelbase

my thought's go with 395-400mm in length would be fine


for what?
a 3905 transmission or the centerdiff?
or both options?

the 3906 transmission is ok if you have it already(steel idler, slipper.....)
if you start with a new car and want to go for a transmission it's easier with a 3905, in my opinion

i would go with a lipoplate not cellplate (under the brace) and a brace design only for a centerdiff for me

Yeah, the FLM mounting adaptor just bolted ontop the chassis plate, raising the tranny a little- the main problem seemed to be you were limited to smaller spur gears since the tranny sits lower inbetween the chassis braces- different shape to the old tranny obviously.

Anyway, I think its personal preference as to whether you go for the center diff or 3905 tranny- the CD gives better center of gravity, less weight, better handling and fewer weak points, but the 3905 tranny is good/better for a wider range of gearing options and requires less custom made parts compared to a whole new CD unit. Either way, you have crazy design and fabrication skills, so it wont be lacking in that area.

On the chassis length issue, my wheelbase is 14 inches, and overall length is 20.5 inches- thats pretty standard for most MTs and truggies roughly, so alot of those shells will fit without much work. I would look at the revo and savage type bodies sold by Pro-line and JConcepts, though 1/8 truggy bodies may work too.

Great CAD work


Have a look at this center mounted diff
in a G-Maxx chassis from Finland


It´s an RCM mount

@SnoopMaxx
thanks, nice car


so i make a new chassisplate last night

1st version was a 24cell sidebyside plate
2nd version was a 14cell sidebyside/ lipo plate (cuted out of a 2nd 24cell plate)

3rd version is a lipoplate







and a short vid




next parts i makt tonight, hopefully

[BL_RV0]

Very nice work man. Keep us updated.

[SnoopMaxx]

That is a sweet chassis
What grade of alloy are you using ?

[Kcaz25]

Lets see the thing!

[zeropointbug]

Yikes, this is kinda old thread, it's like he just up and left?

Very nice looking build anyways!

Hello again,

no sorry, i'm still alive!

but i went back to school so there is not enough time for all the projects.


here's a small update:

the centerdiffmount for my X2CRT centerdiff is already finished and mounted
but because of that i killed the transmission the drive shafts are to short so i make some.

front shaft/ left threaded

those are right threaded

rear shaft/ right threaded


both



overview





next step is make two pressureplates for the rear brakedisc because it has a special outline




first test will be posted

[ANGRY-ALIEN]

Nice!... we need videos... won't the torque unscrew the shafts .... just curious... never saw them done like that before... very cool though

because of that i have to make left threaded for the shaft in the front and i hope the brakingtorque is not high enogh to lose the loctite.

[Kcaz25]

Great!!! What are the shafts made of? I can't wait to see a video. Sweet Maxx!

[suicideneil]

Definately a unique approach to making dogbones, I like it. Also, center diff and brake disc setup is rather awesome
