Got an Emaxx
 

Have a Emaxx 3906(old version) in the mail. comes with

-MIP Cvd's all around
-Hs645mg servo
-tq3
-revo wheels and tires
-powerline shocks
-RRP spur gear



Im planning on keeping it brushed, for the moment, maybe swap the mmm 2200 combo in and out.

Picking up your average everyday brushed esc...


Is it worth wild to do the single speed mod? if so does anyone have a link to it

Looks great Ben! Should be lots of fun. Now flip the tranny, lock it in 2nd, get FLM hybrids, FLM chassis, RPM arms, wing and wing mount, Medusa 36-80, MMM, aluminum towers, skids, braces, and then it should be just about perfect. :lol:

If you plan to leave it brushed, leave the 2 speed. A MM is a good esc to run the titans, and it can also run a bl motor (duh).

As far as the 2200 combo, get ready to change diffs often. And center driveshafts. Old emaxxs are best left light and stock, and moderate brushless setups is all they can handle. I have a bk 9920 and a 15l that I ran on 5-6s that would be great in that truck, as I ran it in an almost identical truck. I will give you a good price on it if you are interested...

hmm.... ill pm you.


think i might want something a little higher kv to run 4s/12c

Yep if you are upping the power you will need to strengthen the diffs and tranny.

thinking of a big motor conversion.. the esc i have is a victor 883. it can handle some big-ass motors (cim), what about a dual 650 or single larger motor?

Doo what im doing on my revo. 970 Kershaw and Victor 883. :mdr:

I may have something you may like for your truck to help w/the upgrades! Just shoot me a pm and we can talk:yes:

Shoulda kept the victor...

i can get another



Forgot to mentiion its got all rpm arms :)

I'll sell you my victor :mdr:

..u wish- who do u think modded it? (me)

if you're gonna run brushed I have an old stomper I don't use anymore. It's the 2 speed and I think it still has a AA battery in it.

also if you don't want to go brushless you could leave it in neutral and make "vroom" noises as you push it.

you could pull it out when the rest of the neighborhood kids play with their hot wheels and run 'em all over

you could bring it to school for show and tell

you could power it with a mousetrap

you could "have faith" it's fast

I'm just bustin' balls man. Make the !@#$ing thing brushless.

the arms in the pics are stock traxxas............

you are correct, i misread his email. I has Rpm knuckles:lol:

Would getting the new maxx spec'd diffs be a good improvement over stock?


already have idlers on the list.

The 3905 diffs are an improvment over the 3906 diffs. They are a sealed diff with an additional spider gear support, but the cup and case are still plastic.

I ran the stock 3905 diffs with 6s and my 1515 2.5d with no issues. The old 3906 diffs I blew out with the titans, so there is a world of difference. I think the extra support and shimming made the difference, as once I shimmed the 3906 diffs properly they were virtually problem free.

My opinion with the 3906 is keep it cheap and only upgrade to 3905 parts, anything else is a money pit and futile at best.

Ask Mike (mkrusedc) and he can tell you, lol!

sounds like a plan then, upgraded diffs and some steel idler.


whats required to install lst/muggy diffs into the maxx trucks.. i would assume some 8mm out drives/adapters.

idk how they would hook up with the MIP cvd's

Probably check with linc on that when, since he puts LST diffs in everything.....

I even think he put some LST diffs in his 1:1 recently......

Here is the muggy diff thread:

$2197.00 to date :gasp:

Hows mileage been since the conversion linc? I have an old Emaxx I wont get rid of because I keep telling myself I am going too get running of but I probably wont. I just cant get rid of it, its what got me started into the Big toys.

And how much in the revo???? :whistle:

Less than half? :intello:

Aren't you glad you own a revo now?!

Your not going to have issues with the maxx diffs if they are shimmed properly... Yes lst diffs would be beneficial to a very powerful 6s setup but in my opinion upgraded diffs are pointless unless you plan to run 6s with a good setup.

I wish that was true in 100% of cases, but after seeing numerous failed emaxx 3906 and 3905 diffs in brushed, novak and powerful BL setups, its just not true. Prevention is better than cure- why spend $$ each time fixing or beefing up stock diffs that will always have weak spider gears, when some modded LST diffs will cost about the same as a pair of new 3905 diffs?

UE or FLM hybrids is something else though, 'price not an issue' kinda upgrade....

^^ I'm with neil on that one. I've shimmed plenty of stock diffs and still blown them. LST diffs are the best cheap solution. I hear Linc even put one in his wife:surprised:

I really think that if you plan to put lst diffs in anything, might as well be a lst... Makes the emaxx look like a toy.

Lst diffs are about the cheapest method to get decent diffs. You will need some sort of adapter or cup for the 8mm pinion, like Mikes adapter for revo center drives to 8mm. Or if you use center cvds, there are a variety of dogbone cups with 8mm holes in them. I used cut down revo stub shafts as diff outputs to attach 3.3 sliders to.

I have beat the crap out of 3905 diffs in both the maxx and revo and have yet to have a failure. This is on 6s neu 1515 2.5d. I think most of the failures were retards on the TRX forums doing back flips constantly and landing big air full throttle. Of course ramming things full throttle and the sudden impacts do not help either.

I agree with linc that the effort in fitting the LST diffs to the maxx are not worth it.

Actually it is a good upgrade, I just meant that a lst is a better truck than an emaxx. I am still looking into having the correct size/shape front supports made, then I can offer kits to install lst diffs in a maxx truck.

Lst difs are the same price as the 4908/3905 diffs... wayy stronger but they throw my gear ratio's in the garbage.... dont make a pinion large enough to compensate...


any ideas?

Hmmm

kind of a useless post ryan...

Im pretty sure i can drill out the cups of the CVD to 8mm no problem.. the only thing im worried about is gearing...

What I cant think out loud? I wouldnt worry about this until it actually happends... No point in upgrading something that isnt broke.

if I put the MMM 2200 combo on it it will break

Your assuming here ben... Thats not exactly true. Your running 4s so it will not be super intense like some setups would be. You may or may not have issues with the driveline. I ran my e-maxx on 5s many times with an 8xl and my HM Car sport esc and it never had any issues with the driveline. Had good power and could pull backflips from a stand still. Alot of blown idlers/spurs but those were upgraded. Its all gearing, weight, shimming, power that determines that outcome...

Why not go to mod1 and use a revo spur? There was a thread in here when BPRevo did his like that.

My FLM hybrids with buggy diffs were expensive but did not mess with my gearing ratios that much and have been rock solid even with me driving like an idiot (standing front and back flips).

...and yes the Revo is much less expensive...so far...

hmm, i think im just gonna wait, run it with the 2200 and replace what doesnt last :lol:

Smart idea. Alot of guys broke plastic bulks and said you should upgrade them. My pastic bulks never broke. I ran them for months.

Think idlers are a must?
