2wd E-maxx
 

Anybody here running a 2wd light e-maxx? I was thinking of taking all my spare parts and putting up a 2wd ultra-light e-maxx using only 4 shocks, my spare gorilla chassis my panter komodo wheels and 4s lipo with a 10L feigao motor. Running weight with lipo would be around 3100g (6.8lbs)
what do you guys think?

It would be a heavy stampede....

Typically doesn't work real well, especially off road. You spend a lot of time spinning tires and little time actually moving.

I think that the design of the maxx platform being built around 4wd just makes it an inherently poor candidate for 2wd. The front end being so heavy just creates too much to overcome for rwd only. Of course eliminating the front differential and drive shaft weight would help some.

13.5" wheelbase, 16" wide, 1.5" gc...not quite the same as a stampede
mine would be more like a rustler vxl on steroids... lol
a stampede is a tip waiting to happen! no fun in that for me...

thanks texasSP,

I would have the motor & esc in the back like my original gorillamaxx so that would help. :)

Well, then just do it.

lol sorry for not agreeing with you JThiessen...
no hard feelings! :O)

I ran a super lightweight emaxx 2wd. I used the stock plastic chassis and a feigao 15l/9920 combo on 5s lipo. Great truck, geared for about 50mh it was a blast. Liked to do wheelies, but that is half the fun. I had a single speed gmaxx tranny, no front diff, driveshafts or front center driveshaft. It never broke either...

cool! I'll give it a try and see how light I can bring it... do you think i could get away with a S can motor?

Nah, L can is about the minimum. I would almost say that you may want to go to 5s lipo... But depending on the gearing the 10l on 4s should be fine. At 35mph it will do fine, not sure over that. Feigaos are not that effecient...

I've seen a 2wd emaxx being ran on a single 2s lipo and MM system (esc and motor, I forget the kv rating), and it ran well enough. Lots of wheelies, and impressive power and speed given the platform (it wasnt a lightweight truck as such). An S can should work, but I'd prefer an L can just to be on the safe side- suck it and see I guess.

maybe If I find one cheap I can go with a lehner basic 4200 on 4s lipo!
I think that would make a nice light set-up...

I have a 5300... Bit fast for 4s though...

Someone here was selling an xl 2400 lehner basic, can't remember who.

lol just a tad! Do you think that small motor (basic) can carry 6lbs around on 4s lipo?

No skin off my back! Just shared my opinion as you asked for!

the slash and new emaxx have exactly the same wheelbase.
widen the slash with the rear arms all around or the jato wide arm conversion, add half offset truggy wheels and the width might also be similar.

punt an emaxx body on and you have a lightweight 2wd emaxx....

hey, my stampede dosent tip over. and thats doing 30mph power slides on-road with moabs . 12.5" wb, 13"with, 1 3/8 gc...... actually i was thinking about doing the same thing. although more of a buggy.

Do you have a stock chassis to use? Would be much lighter tht way. You could take out the diff and tranny and put an outrunner where the diff would be. I bet you could get the truck under 6lb rtr with that setup on 4s.
You could try something like this:

Maybe have mtxmugen rewind it to ~180kv.

Here is my old E-Maxx in 2wd. I broke a front diff and just pulled the driveshaft. This was my light-weight truck that I ran on a VXL system for a long time with no issues. Lots of people know the truck from the TRX forums, but I don't think I've posted many videos on here. Sorry for all the downtime, this was before I knew how to edit videos.

Edit- I forgot, a 2wd E-Maxx does NOT like to stop! Just locks the rear tires up and spins.

There's no way that was a single vxl. Surely a long winded literary battle is necessry for us to ascertain what was truly beneath the lexan lid of your "2wd e-maxx", if that's even what that was. It sounded like a kyosho....

BL-RVO, the oribinal al. gorilla chassis (2mm) come in lighter than the stock e-maxx and is way better for CG.
I counted everything yesterday and I could bring it down to 5.5 to 6lbs with the 4s lipo batts! A 2wd slash weight 5lbs with 2s and 5.5lbs with 3s lipo so
my ultralight maxx is going to kick ass I think!
I've got al turn, al pivot balls, no shifting servo, removed first gears from stock tranny, 4 shocks with trinity heavy springs and 50wt oil, no bumpers, rpm skids, panther komodo tires on claws wheels (145gr each) removed front diff and sliders, al. screws all around
right now i'll put in my 8L but probably a lehner basic ot basic xl soon

I think it is. There are guys from the TRX forum that heve seen it, and there were vids of him racing one of the guys with a MM-7xl on 4s, and it was a close race. The 7xl beat him most of the time. I put one in my E maxx to see what it would do with a MM and 14 NiMh. It was fast, but hit 170f in about 4min. Made me laugh though. Stum also tested one in his revo conversion to see what it would do and got 37.9mph out of it. He has a vid of it. I'll let him post it if he wants. Not a recomended setup by any means.

i woudnt try a vxl on my e-maxx! my 10l on 4s minimum! unless your running a light rig like mine! but no way on the stock one with those heavy tires...

Haha. I've dealt with this for a while. Take a gander at this video :whistle: And this was in 4wd.

Edit- Oh and this is the truck after a long, hard bash session :wink: It should clear up any misconceptions of what is "beneath the lexan lid".

6.8 lbs, that sounds familiar.

very nice Serum!!
was that a basic or basic xl on there?
I really like what you did with the bulkheads
where you able to run stock sliders long before twisting them?
do you still have your?

Wow, that single vxl can is impressive. That dog didn't seem phased at all by the rc passing by. My dog (in my avatar) would have been chasing it like crazy!

The dog hates it. When I first got it I hit her at about 15mph and she has stayed away ever since. And she is 16 years old, not really one to chase cars anymore. I originally built the single VXL truck to see how well, if at all, it worked. It turned out so well that I kept it much longer than I thought I was going to. In all those videos it was only geared 66/18(stock). I geared it to 64/22 and it was much faster. The temps got high, up to 185 so I dropped it back down to 64/20 and it was plenty fast. When I raced the MM/7XL/4s the race was very close. The difference was the driver. Once I raised the gearing a bit the VXL was much faster than the 7XL. His truck was very heavy, though.

I am guessing you ran 3s with the vxl? If so your 64/20 gearing is good for about 40mph. I got an emaxx to do 55 with a s can feigao (similar to the vxl motor, but it was higher kv). I was suprise how much power the s can motors could put out. It did not have any issues with my 4wd emaxx with 22/54 gearing, but it did pull enough amps to overdraw the lipo and thermal the MM. If I had the better lipos I have now and a MMM it may have worked. Second gear was good for 70+mph in theory, but the esc would shut down if I tried full throttle in that gear. Motor did not get too hot either, even with 100+amp draw. I have a feeling the crappy maxamps 3s 10000 lipo was responsible for the mm cutting off.

Yeah it was 3s Venom 5400mAh LiPo. Not great packs, but good for 40+ on my truck. Noone believed me for the longest time on there though.

Impressive. I'm going to build a light maxx with plettenbergs custom chassis on phaltlines for speed. I like the maxx tires cut like that, but what a PITA to do. bowties on dishes would lighten it more.

I agree I ram my maxx in 2wd for a while. Here's a video if anyone is interested.

Yeah, but I was broke when I built it. Couldn't afford the wheels. So I just cut and smoothed these. I also shaved the insides of the wheels to lose even more weight. I went as far as cutting the driveshafts down to lighten the rotating mass. This was an unbelievably light truck. I used 3.3 driveshafts and 3906 axle carriers. This saved weight after I modified the carriers and it also let me use only one bearing per wheel. The tranny got all the lightweight stuff and there was no metal anywhere on it. It was the most durable truck I have ever owned. I thought I would build a V-Twin along the same lines as the single VXL truck and it was a nightmare. Way too fast, way too light and way too fragile. I twisted the light weight output shaft into a pretzel in no time. The 3.3 shafts break every run and the truck can't handle the speed so it breaks every time I ring it out. Here is a video.

And this is my favorite..

Nice videos man. I miss having a maxx. I want to purchase a roller once I'm done with my rustler.

It is an XL2400; the rear driveshafts where replaced with two UE shafts. They turned into pretzels quicker than expected..
