Muggy diffs in a maxx
 

Muggy diffs in a t-maxx, why you ask?? because in LST-2 diff cases these things are almost indestructible!

comparison of stock vs muggy, gray VS black (and im sure that 99% of aluminum bulks are cut like the black old school bulks)
any one with the FLM chassis could you please measure the height of you frame braces, im planning to use those but up side down thanks :)

So, what mods are need to do this(to the bulks/diff case)? It looks pretty cool!

Bye:mdr:

Very interesting, are the muggy diff cases the same as the lst/aftershock cases? These are the real hybrid diffs, parts from all over the place!

they are almost the same, difference is different pinion ring gear tooth count.

are these alot stronger than the maxx diffs?

Hmm, that looks very promising- keep us updated dude.

Yep, the lst/aftershock/muggy diffs are very similar to std 1/8 scale diffs, 6 gear spiders and you can get TiN coated gears for the lst 43/13 ration, which should help them last. I think my new 20xl hv maxx will use this mod, thanks its me for the great idea!

here you go George and for any others that have not seen the inside of a LST/muggy/8T diff.
very nice helical cut ring and pinnion

some have asked and yes the diffs are very very strong, my twin motor has yet to kill one yet.

all i can say is zuuuuuurrrrrbbbbbbb...... :lol:

In the above pic, what did you use as the metal shim to make up the difference in diameter between the muggy diff case and the hole in the maxx bulkhead?

Also, how did you get the retainer/locator ring to fit the nose(pinion) area of the muggy diff? The lst diff case I took a look at was larger in diameter than the inside diameter of the ring.

You can also get the ti-ni for the muggy ratio (45/11), just use Mayhem ST gears.

Drill/ dremel and PVC pipe for the spacer, try to get a tapered 1/2 PVC so when you slip them over the diff they wont pop out the bulk head.

you look right at the diff and you can see how much I drilled the yoke thingy, all of this only take about 15-20 minutes to do.

Did you mention twin motored truck just now? I wanna see that thing man...

i was waiting for my buddy to teardown his lst to try this exact thing out,darn it! btw lst aluminum diff cases are only like $10!

here you go :)

If you do try this out watch ebay for the diffs, there super cheap!!

Oooh, nice. I was expecting to see a dual Bl truck, but that twin nitro powered thing looks just as cool!

LOL sorry! I should of said what it was:lol:

Is this a Revo A-Arm?

Can you tell me what have you using to attach the stock e-maxx driving shaft to the new diff output (on the wheel side, not center drive shaft)??
The only parts i can see to fit is tihs:

I thnk that i'll try to put this diff in my revo bulk, maybe i'll save lot of $$$ and don't have to buy the V" hybrid!

Yup thats the one! BTW ive all ready tried fitting the diff in the revo, doesnt really fit at all... If I find a way ill post how I did it.

OK i know what to do. A friends of me is ready to trade his E-Maxx against my revo. I'll do it right now i think.:intello:

Forget to ask you Its Me, what's the diameter of the Muggy pinion gear shaft, because i've this part here at home http://www.rc-monster.com/proddetail...mrevov2coupler

Why on earth would you want to trade a Revo for an E-Maxx?

If it was the new Emaxx, or a seriously upgraded one, I could understand that. But the Revo is so solid and flexible (nice oxymoron there) you cant beat it... so long as you're happy though I guess.

My friend have an Gorilla single speed tranny, aluminium frame, Power Stroke shock. The only thing will be the add of the muggy diffs.

Why??? you'll keep the revo if you are me?

Well, the diffs are the weak link in the traxxas vehicles, all of them.

Is your revo stock? You can always buy another revo, not like there is any shortage of rollers for sale. I am going to try the lst diff upgrade on my t maxx build, we will see if they can hold up to a 20xl on 10s lipo! I also have an aftershock that I am converting, I am upgrading the diff cups in that to the nova 7075 units and using the losi TiN coated diff gears. Plus I have a spare pair of HB hardened diff internals, hope that they fit!

Hey James, you're the only guys here who not send me christmas gift, i always wait for pair of Hybrid diffs for my revo:whistle::lol:

As soon as I get them I will make sure you see them again!

:slap:

Slap in the face, huh?

When did you ship them by the way? I am sure that the slow ass US postal service are taking their time as usual!

I have been hammering them in my twin for some time now with out any signs of wear :), Ill be dying to see how they work for you!! I am also planning to build this maxx with some serious power behind it :)

yup man! they are 8MM


On a side note... what would be a faster set up?? new emaxx trans and a out runner or buggy center diff and what ever motor you guys tell me to put in it? I am a complete electric noob and this is my first brushless build.

Buggy centre diff and an inrunner would make for a cleaner & lighter setup, but the emaxx tranny and an inrunner would be just as nice. Outrunners per say are better suited to direct to diff conversions- they have a very low kv rating normally (you want about 2000kv or so for 4s, or 1600kv for 5/6s operation).

I have a feeling that the outrunner on the new emaxx tranny will suprise many. Having some gearing and a good slipper will really make the outrunner work well. I will try my 2826/12 in my new emaxx on 5s with lst diffs and see how it does. Gearing will be 20/38 or close and with the two speed it should haul butt. These axi outrunners are really nice, and priced very well considering the quality.

I also would love to do a direct to diff but am unsure of what out runner to use for this?
Thank you both!! ill be lerking and reading for the emaxx tranny with a out runner, only reason I was looking at out runners is because it looks cool as hell :)

I am beginning acquiring parts to do a new emaxx with your lst diff upgrade. I plan to run an axi outrunner on 5s thru a quark esc and see how it works. I will most likely wait for traxxas to release the two speed kit and see how that works. I may also do a single servo conversion, as I will need a pair of matched servos for the chassis I am buying. Already figured that out! I think the combo of the great revo slipper and some gear reduction with the tranny, plus a two speed will help the outrunner and its torque production.

Hey guys, could you tell me what's an inruner, and this direct drive innruner????? You lost me now:lol:

Inrunners are the typical motor we use. Feigao, Neu, LMT, etc. I assume you know what outrunners are since you didn't ask about em. :mdr:
