I talk to their techs all the time and in private they even hedge when asked about 4S.

That's great!.. I never talk to any manufacturer tech's because there is no need! (you probably did not get that so I'll break it down for ya) No need meaning the RC's I own don't break! If they do I know how to fix em!!:lol:

Really? That's cute! Please refer to the link I posted up top...:rolleyes:;)

Be that as it may, I build Traxxas cars for 3 different people who all run 6S and none of them have much problem beyond a shorter maintenance interval on the driveline than one might have running 3 or 4 cell...

Don't really care what you build, you could build a frickin Zephyr, the facts still remain!

Oh and they are all street/rally cars. Two are 4x4 LCG slash converted to street and one is a rally and all 3 are fast as hell. :D

Metal or a monument?:lol::rolleyes:

I sent you a PM with the link to this thread so you don't forget to come back! I know how you 4 post reading posters like to post...;)

Sorry.. I had to register JUST to respond to this..

I can't post URLs to other sites yet so I'll quote the overview page of the E-Revo Brushless Edition section of the official Traxxas website for you..

"Built For Brushless
We built the E-Revo for 6-cell LiPo and brushless power right from the start. For other companies, brushless-ready means just making some nominal provisions for battery and motor installation and letting the aftermarket develop the upgrades necessary to make it survive. Not Traxxas. We heard the call for more power so E-Revo was tested tough for durability with brutal 6S LiPo power and intense custom-wound brushless motors. For the uninitiated, this extreme 65+mph motor and battery combination is ordinarily a predictable recipe for a box full of twisted and mangled parts. Not so with the E-Revo Brushless Edition. E-Revo's driveline has been engineered to endure the kind of horsepower and punishment that's possible with today's motor and battery technology."

Don't get me wrong.. I LOVE my Revo. I have had it since the day after the 2.5 came out. That 2.5 was converted to a 3.3, then it had an OS21tm, then an LRP.28R and now I am in the process of converting it to a full on E-Revo (Not just a conversion kit, I'm swapping the chassis and everything).

The Revo is the only RC I own, but far from the only one I've driven. I LOVE my Revo and I think Traxxas is a fantasic company. However..

They really didn't design the diffs well at all. They are far too small and too weak to be considered durable for even the 3.3 nitro engine, much less a brushless motor on 6s. A truck that size, with that much traction and that much power should have had an 1/8 scale diff from the start. Which is how i found this thread in the first place.. Google for "rc monster hybrid diffs rerelease" brought me here because with as much money as i spent on replacement diffs through the years, i want something that is going to hold up to my new 2200kv brushless motor. Even if I'm only going to run it on 4s.

That may be true for the 1/10 scale stuff with the Velenion systems like the slash or rustler, etc.. but if you try to run a brushless revo on 3s you are only going to cook your battery, or fry your ESC. The voltage is just too low. You NEED at least 4s to run the Revo.

And one last point.. The newest brushless E-Revos come from the factory with 2 3s lipos and the ESC is wired in series.. If Traxxas never meant for the vehicle to be run on 6s, they sure are doing a great job of covering that up..

And hey, I'm not picking on you.. You asked a question and I'm answering it is all.. no hard feelings.

OK guys, I like my crow with a lot of salt.

I'm a nitro MT guy because of all the problems I see and hear about from people trying to run large scale electrics.

Everyone I know who race 8th scale have tried electric and are moving back to nitro because they are tired of the constant trouble they are having with ESC's, BEC's, and servos burning up or failing after a short period of time.

We all race 2wd and 4wd 10th scale electric and have zero problems with that but every racer around here who runs 8th electric has been frustrated by a high failure rate of the three components I mentioned.

Either way, enjoy your dog piling on someone who got caught out writing checks with an alligator mouth that their hummingbird azz couldn't cash.

I'll be sure to read more on large scale electric before I run my suck in the future.
