lookin good so far, those axles are going to be hot.. cant wait to see the final build.

[Toph]

Very unique idea on using the Losi Aftershock diffs!! It looks great so far!! Keep up the great work!!

[mxracer525]

looks like its gonna be sick, got a ? tho, wats the hydro. suspension? and adjustable height servo?? just some fancy words to say that you'll be able to lift and lowerl the truck at a touch of a button??

Hey thanks guys !
Can't wait to have a tube buggy

Yep ! you got it. it will help with steep hill climbs and the COG


Finished mocking up and Spot welding the rear axle yesterday :-P
Interesting part of attaching the axles to the Diff in a Clean scale manner, hmmm
rear axle 0* caster

[mxracer525]

thats gonna be sweet, them axles are beeef! and they look killer too. what kind of design you gunna go with on the tube frame.?

Cool thanks !:-P I like scale looking rock buggies and there's a lot out there. So I'll be searching Pirate4x4 and my picture archives

I like Detail & unique so I'll find something then tweak it a bit

here's a few I like,
Sniper & well I'm really just liking Sniper, but if I were to build a 2.2 then it would be like the new single seat competition crawlers

Interesting idea on the Wheel weight. I'd like to hear an update after you get to run this thing. It's looken really good so far.

[roktoy]

Like the axle build....those will look great.

Keep the pics coming.

[SnailMail]

the R2 s speed is shifted by a servo? i thought it was automatic......

[Cslax06]

Wow this is a pretty killer build. I love those axles.

[Wingin' It]

Killer axel set up. I thought of going with SS but was worried of the weight. Looks good !

What I have learned from 4 wheeling and my current RC super is that you want low weight. So the Axles are a great place to have heavy weight.
I think aluminum is to soft.
Keeping the weight at axle height and lower will give you great COG results

Thanks for the axle props, I may have rushed the build on these though
I was building them thinking I would just attached them with plates like all the other emaxx tube axles guys do. But I want something "Cleaner" than that. So back to design board,

Question? :
What do you guys think about attaching the Large 1" short tube to the Diff with Brazing or JB weld and then Insert the 2nd tube ring inside and fastening toghether with 3 small short button head screws ?
so that the axle are removable. I cannot remove axle shafts from the outside ends because the dogbone end pin is slightly to large.

I doubt the OFNA Jammin universals will break so I could Braze or JB weld the whole axle together ?

Idea
Drawing is with screws
Left First Tube is 1" with smaller middle tube snug fit inside 1st tube
Diff housing is ALUMINUM
Tubes are steel
Now that I think about it, I cannot Braze Aluminum with Steel. I would need to use a Metal bonder like JB weld for this joint

I was looking at the second picture say to myself that looks familiar then it click it was my axle picture. I still have a lot to do to mine. I sracpped the tubber chassis in favor of a stick like chassis.

Yep , it was the best picture I could find.
I have yet to see a real stick chassis on a max driveline
Very cool though

[toy4crawlin]

Build update: Wheel Locks

RC4Wd has a disconnect tranny to disconnect rear driveline so you can steer tighter.
but right now it's only single speed, if they come out with a 2 speed version then I'll use it and add a Line lock for the rear brakes.

If Not, then PLan B:

Adding a driveshaft Brake for the Rear Driveshaft.
and use the mechanics like the gas powered rc's use for brakes, like an old RC10Gt

Thanks to the Maxx sticky thread http://www.rccrawler.com/forum/showthread.php?t=5371
I'll be using 5457 yoke for the rotor brake
and the 5453 for the 5mm tranny shaft
and the 5458 for the 8mm Losi Pinion shaft

Humm... I ran out of radio channels LOL
Servos:
Ch#1 Throttle
Ch#2 Front Steering - 5955 servo .
Ch#3 Rear steer - either a 5955 or a 5995
Ch#4 Suspension- adjustable height servo 5955
Ch#5 Front Dig/ rear shaft lock, servo #?
Ch#6 Tranny shift servo. stock servo

[toy4crawlin]

UPDATE:

Well this build will be much slower than I had hoped.
My spending is out of hand, The last 4 months I have SPENT $3400.oo in RC Hobbies, My Toyota crawler, 2nd 4runner , and Tooling.
But the plans on the axles are almost finalized.

Build progress change:
Change in Design on front axles

Braze Aluminum sleeve on Diff cover and use bolts to connect stainless axle housing

also this wheel width is looking like 16" + so I'm most likely going to use OFNA Hyper 8 Axle shafts that are only 5" long each
wheel width should be around 14"
Wheel base around 16.5 or 17"



Another Mod:
6 LED Rock Lights , 2 flood offroad front lights & 1 interior light,


New Parts:
RC4WD 2 Speed tranny & Revo shafts for drive shafts
1/10 scale recaro seats

[Crawler Noob]

damn, those axles look killer.
