build a gmaxx and i need help

[JoFreak]

no, only between the hybridbulks and the diffs, I only had to shim the piniongears.
as for bashing: no idea if the gorilla or FLM is better, I like the looks and layout of the G4 better, so I would choose it, or so I did but it was a G3 back then...
if you take the traxxas diffs you should probably go to use the stock bulkheads so it doesn't get a too big a loss if you decide to get some hybridbulks later ;)

if money isn't that a big issue for you, go for the hybrid bulks and the HB diffs form mike's shop and stop worrying...

Yeah, very much depends how much you want to spend- stock towers are weak if you crash or flip, same with bulks,- the stock 3905 diffs are alright, but eventually even they will fail with a MMM setup or similar. Only if you're on a tight budget would I suggest sticking with mainly stock items. Like I said, its all very much personal preference for alot of parts- take a look around at other builds and see what you like the look of-, there are some nice variations around the forum on the 3905 platform, take this one for example:

thats a nice truck.
a FLM truck will be cheaper...

i found this http://www3.towerhobbies.com/cgi-bin...&I=LXLGX2&P=SM
i like towers and would like to shop as much as possible there. that pinon do i need?
some other diff suggestions?

will all 3905 parts fit the FLM chassi? tran.?

just put shims between the diff and bulk. to center the diff?

what do i have to choose between if i would like to use 4 instead of 8 shocks?

i think
- G4 chassi
-hybrid bulkhead
- HB diff
-MIP center
-stock CVD
-FLM tower
-RPM arms
-MMM combo
-6s lipo

ha ha my wife will kill me.............

Thats the right diff, you just need the matching pinion and bearings, and a few 10x8x0.2mm shims/washers to set the mesh correctly- given the shipping costs from the usa to sweden, it would probably be cheaper to buy the diff kit from Mike, that way all you need are the shims.

Ofna diffs will fit too, but I dont think the V3 revo ones will as they are narrower.

All the 3905 parts will fit the FLM 3905 chassis- tranny, receiver box, steering mechanism etc.

You should only need to put one or two shims behind the head of the pinion gear, between it and the inner bearing to set the pinion depth- shouldnt need to put any either side of the diff to center it, but you will soon see if they are needed once you start assembling the hybrid bulks (different people experience different requirements due to minute differences between the bulks and diffs & bearing etc).

I have a tutorial of sorts on assembling 1/8 scale diffs- I used UE diffs, but the same principles apply to the hybrid bulks:

http://www.rc-monster.com/forum/showthread.php?t=8012

If you want to use the stock drive shafts or cvds, you will need to purchase those output shafts and swap them over onto the diffs, otherwise poeple find the stock drive cups to be a bit shallow for most cvds (you can always find deeper drive cups though, depends what you plan to use really).

For 4 shocks, I would use for ofna truggy shocks- also sold as super shocks by UE (though UE dont sell outside the USA so you will have to look around for them- ebay).

Not a cheap hobby for sure, but jusr point out the wife's dress, jewellery and shoe collection, Im sure she'll be a bit more understanding then...

Stock emaxx diff wont last long with brushless power, 1/8 scale diff are the only alternative.

Are you talking about 3906 or 3905 diffs?


And what the hell is up with G-Maxx? Why are they not offering the g4 chassis? The economy is that rough? Are they trying to focus all their energy on the ever popular slash crowd to make $$$?

[Rivermaxx]

I am talking about both. They simply wont hold up too a good brushless bashing at least not for long. Although the 3905 diffs are stronger than the 3906. Thats probably why traxxas never came out with a brushless emaxx..

[Maxxrickard]

but mike dont have diffs, he is out of stock. and what is the difference between HB lightning and lightnning PRO? should i take the "PRO"?
just put in the diff and pinion in the hybrid, nothingels?
i shop gladly at Mikes but everyting is out of stock...

FLM towers, is it one or two i get in one package?
screw to the hole car? screw to fix the shocks to the towers? i think i will go for the traxxas big bore(8), is that a god choice?oli?

for start i need.
-chassi (out of stock)
-FLM towers
-FLM hybrid bulkhead
-HB diff (out of stock)

The Pro diffs are from the truggy version, means they have a smaller pinion gear.
Since you want to use a tranny you should use the non-pro diffs.
And yes, only drop the pinion and the diff into the hybrid bulks and you're good. But don't forget the shimming!
And get two of the Hot Bodies drive cups: C8068 (M4 set screws not included!).

Don't worry about everything beeing out of stock, just send mike a mail with a list of all the parts you need and he will get them all as fast as possible.

Regarding the FLM towers: just write that you need two towers into the list for Mike and you should get what you need. But I would assume there is only one tower per kit.

As for the shocks: I can only repeat myself, I would go for the ofna shocks again!
It is possible that Jamara is the official reseller for Sweden as well as for Germany maybe you can get those form a lokal shop if you want.

The screws for the bulkheads are included with the bulkheads, as are the screws for the shock towers included with the towers and the screws for the chassis are included in the G4-kit and so the story goes on and on...

I started with 40wt oil for the front shocks and 35wt in the back, 7k oil in the front and 3k oil in the rear diff. This should be a good starting point for you as well.

[Maxxrickard]

okey a non-pro diff. but i will use traxxas org. CVD, so i dont need the drive cups, but thanks anyway.

can i get a link to the shocks? do i use 4 of ofnas shocks?

just send an mail?okey thats easy.

[Maxxrickard]

is i possible to build without a tranny? how?can i do it with a G4?tell me and show me pictures thanks.

[Rivermaxx]

You need to search this forum and check out other peoples rides. All the info you need is in other peoples build threads. You just got do the mouse clicking to find them. It may take a while but you will have more knowledge than if we did all the work for you.

[Maxxrickard]

im sorry... but i dont understund everything i read.... trust me i have lookt in hundreds of threads. but i still would like to get answer in this thread. if anybody would like to answer my questions her i´ll be grateful.

but i cant decide what chassi i´ll be built from. i lika GM but FLM is also beautiful... is it worth almost 100$ going GM?

[suicideneil]

You need the HB drive cups, the 1/8 diffs have a larger input shaft size (8mm vs 5mm). Read that link I posted, all the info is right there.

You can build a truck using a center diff instead of a tranny, but it will be a custom job Im affraid; either home made, go to a machinist, or see if Mike releases one in the future (we're all waiting for a 3906 chassis version presently).

There are dozens of different emaxx builds, so I strongly suggest reading around for info- you wiull soon see what parts are good and which arent, and where to find them (ebay, towerhobbies or amain usually, though Mike sells some good stuff too).

Shocks = look around and see what other people are using, but 4 truggy shocks will work fine- rc8t for example with stiff springs.

[Maxxrickard]

im sorry
yes i have seen what other people have use to built theirs trucks but i need straight answers... but yes i read alot and then i ask questions here. my problem is that i dont understand all language.

i need to no if i should use RPM arma or FLM arms??
FLM chassi or GM.
any diff that fit traxxas org. CVD or must i use steal?my last MIP cvd was to short and didnt fit.what cvd is the best?
and what is UE???

please...
