Am I Dumb
 

I recently picked up a crappy tmaxx 2.5 for 75 bucks. I hate nitro so tossed all the old nitro junk and put an emaxx chassis on it. The question i have comes in the transmission. I have two stampedes laying around so i took one of them apart and crammed the tranny in the emaxx. In the future i really want to go Brushless. Can i beef up a stampede tranny enough to handle a brushless setup like a novak HV-maxx or am i dumb for trying? Is the 2.5 tranny worthy of the abuse/convertble to electric. Any info on the subject would be great.

You can make them pretty strong but it's probably not gonna be worth it by the time your done with buying the steel diff,idler,making a strong enough motor plate for a bigger motor,adapting a suitable slipper to the top shaft(unless the new slipper is up to it and can take the revo gears-i don't know).the out drive shafts are smaller too aren't they?If you can make it work with bits you've already got then there's no harm in trying-except to the tranny,it'll probably go south.

yeah you could adapt the t-maxx trans,been done before.or you could just drop a centre diff in instead.

Welcome to the forum.....

I would be concerned about the diff in the stampede tranny... it's not made to handle the stresses it will see in the center of an Emaxx. That's much different than a final drive in a 1/10 truck.

But it's an interesting mod. Try it and see what happens... but I have doubts about it holding up too well, modded or not. I take it you didn't have an emaxx tranny?

The best solution would be rcmonster's slipperential... but that's not meant for a budget project either...

wow, thanks for replying so quickly but i now have some new questions. do people normally damage output shafts with brushless setups? And is the new revo slipper on the pedes able to handle that kind of power? Gotta ask before i spend 150 on trans upgrades and find out the whole thing is junk. Thanks again.

Well... the Revo slipper should be pretty good. I ran a Robinson slipper on my maxx.

The original emaxx slider shafts used to look like pretzels after running a high power brushless setup... but he HV should not do too much damage. I ran the old Hacker C50 setup (similar to a HV I would say) and the rear center shaf thas to be replaced with a steel CVD... and the rear axle sliders did twist quite a bit but still worked. (I actually swapped sides after they were permanantly twisted... and they worked good after that :) )

Use a mild setup like the Novak and keep the slipper working... and it should hold up imo. You might have to make the Pede diff a spool... fill it with JB Weld or something ;)

well i wish i still had the emaxx trans but i was dumb and sold it on ebay because i needed money for my clod project (which sucks). but this is what i wanted to substitute, flm alum tranny case, rc-monster alum. diff, one peice steel diff locker i found on ebay, and the steel idler gear. The transmission mounted up pretty easy and i used the halfshafts from my old emaxx as driveshafts. I have the newest version of the pede with the revo slipper so i was hoping that would workout in my hv maxx project. Any info on do's and dont's?

using the t-maxx transmission makes alot more sense.i certainly wouldn't throw that kind of money at a pede tranny,you can get a sorted e-maxx tranny in there for less.

i am only 17 and dont have many resources to make my own parts thats why i want to stay away from using the t maxx tranny. It requires more engineering than i think i am capable of and even if i could fabricate something im sure it would not be good enough quality to last in my truck. The pede tranny was easy to mount and i think it has potential. I will however take the t maxx option into consideration because i am going to have plenty of time before the money is there to start spending.

If you already have the tranny built up like that... run it and see if it works. All we can do is speculate....

I have the stock stampede tranny mounted in my truck. It works but i havent put any serious power to it, just the 12t stampede motor and esc. The diff definately needed to be locked so i took the jb weld to it. Its way too slow and i wanted to consider my options before spending money on what started out as a low budget project. I was just intrested in having an alluminum tranny with all metal gears for under 150 bucks when doing so to an emaxx trans would cost much more. I also like the idea that the stampede trans is easy to work on. i am just curious. thanks for the response

Since money is a factor I wouldn't worry about spending $150 or so on the stampede trany and hope that it works.
I would look at geting the t-maxx trany to work, but I know nothing about them so I don't know how hard that will be.
To build a 2 speed e-maxx trany from scratch with steel idlers I think would be maybe just over $70 (with stock motor plate) plus what ever slipper setup you get. If you only want one speed add about $12 for the single speed coulper (you can make it single speed without it, but it will be stronger and smoother with it), but you won't need the $13 1st gear idler or 1st output gear (I think about $3-$4).
I think to build the Gorilla Maxx single speed transmission conversion (only uses on half of the standard transmissin) would be about $100 plus slipper.
There isn't really any need to get an alloy transmission case for the e-maxx imo.
You can get some of the stock transmission, motor plate and slipper parts fairly cheap of ebay sometimes though.

Once you decide to go brushless do some more research here (theres a lot that can be learned), most people will tell you there are better, cheaper systems available than the novaks.

Thanks for all the info u guys rock.il post details when i finally get around to the build.

If your going to pend $150 on a Pede tranny all decked out you can get a Emaxx tranny for $80 on ebay and then a steel idler from Mike for $15. Thats cheaper and stronger and it fits without any hassel?

Not quite sure why you are looking to build up a $150 stampede tranny to see if it will work. Take that same $150 and you can build a Emaxx tranny with all the bells and whistles. You dont need an aluminum case on an emaxx tranny for it to be strong enough. Stock with a 2nd gear steel idler. Lock it in 2nd gear with a bent piece of wire on the shift fork and your done.
