Dual motor 55T with Dual esc ae-5 mad crazy torque

[Shan Newton]

Yes it's heavy no twist from torque and no lean... if it fits it sits...

Now just gotta tidy up the wiring and paint the shell. That's my jeep and that the color scheme I'm gonna run... will post more pics after its done...

I know it seems like an impressive setup but ultimately one good motor in the 27-35T range (especially on 3S) with the proper gearing will have more torque, more wheelspeed, better low speed control, and better brake hold. You get more torque to the wheels through gear reduction than adding a second motor. The dual motor setup just adds a bunch of weight up high and eats batteries faster.

Yep really wasn't looking for your opinion on how that exact same setup I used to run it just wanted the maximize it... everytime someone who posts a dual motor setup says the same thing over and over again just appreciate it for what it is and your knowledge is just a cut n paste of all the other posts I have looked at.... sorry but I did it my way cause I could... and as for as brake hold seriously... until you have driven it you don't know... heavy yes but I don't care... it a rock crawler...

Then don't post here.

My opinion is that it is dumb.

[Shan Newton]

That I can this forum is so old anyway....

Well then, go back to flex fridays on Facebook.

[CoolRunning]

So a new shiny forum with crappy information and locals with less knowledge would be your preference?

From my searching and reading this is it for crawler and Axial stuff.

A year and a half ago I would have called you an arshat, this morning I smiled and got a warm and fuzzy feeling when I read this.

I for one enjoyed this build..very creative fabrication..nice work. How did you make your motor pinion gear covers?

[01f1502wd]

What is the point of having two motors? How do they tie into the trans/t-case? Do they seperate so you can power the front tires faster than the rear? I would like to request for more pictures please

All of that is available bolt on and available commercially. Unless you are seeing something I am not, I'm going to assume that you mean the spur gear covers? They are just vacuum molded lexan.


Under 30 bucks on amazon or new egg, 10 bucks on flea bay, you too could have an extra motor on a already horribly over powered(by that I mean no where close to scaled) truck.

I think a good quality single motor on something like 4s lipo will provide as much power and torque as most people would need but if you're on 2s or even 3s lipo then dual motors is a "good" way to get extra raw power for not a lot of money.

[EeePee]

Uh, or ugh, not really.

The are more disadvantages to running dual motors than there are advantages nowadays...that's really all there is to it. Back in 2008 maybe it was viable to run dual 550s in your E-Maxx because that's all there was. If you want cheap torque now just get a sealed 550 can, gear to 10/56 or something and run 3S.

[whitrzac]

It's something different, power is all personal preference.

You probably don't need 2 escs. Try to run it with 1 and just watch the temps to make sure the esc doesn't get hot.

Perhaps that's not enough power though.

Where as a cheap 550 on 3s is a good budget setup for power & torque, the 2 x 540's on 2s will still be more powerful and on 3s, it wouldn't even be close.

The pros are cheap but huge increase in power

Cons are
More load on the ESC / battery
More weight high up
Spur gears will wear much quicker

Right, and with those disadvantages I'm not seeing the benefit of spending $40 on a motor plate + cheap motor when you could just buy a single higher quality motor and have a lower CoG and have way longer battery run time. Also, motor turns isn't really telling the whole story. Without dyno testing we can't say for certain, but if you handed me a rig with a single 45T torquemaster expert or said I could have the dual 55T sealed can rig for a sled pull, I'd pick the single motor any day. Then again, sled pulls are a once per event thing, and I've yet to see a situation on the trail where 2 motors > 1.

At the end of the day, it's still OPs rig and none of us will see it so it doesn't really matter what he does.

$40?
More like $7 for a dual motor mount off ebay and 2 x cheap motors (GoolRC etc) at less than than $10 each

Level 3 RC mount = $12
2 x GoolRC 55T = $20

That's what I see on ebay, so lets just say $32...really don't see the benefit of saving $18 here to drain your battery faster with a higher CoG still.
