If it makes you feel better, go for the 125B!

Here is the deal;

125X14V=1750W
80X14X2=2240W

I'm a nitro guy trying to convert to electric, so i don't have a FEEL for anything yet. But I do work in electronics and understand a few things about heat effects and running electronics backed off from their maxx ratings....

In less words; yes, i think two 80B's would survive... :)

This fits? Pics installed?

The Dual mamba maxx 5700's sounds like the best bet to me.

0700 05.23.2007 03:00 PM

well 1.7" long is going in correct direction! I'm starting to think these are the smallest motors that will fit the Emaxx???

Serum 05.23.2007 03:44 PM

I would not use these small motors personally; if you want a real deal 2 motor setup, do it the right way, or stay away from it. that's my opinion. like i said; use 4S on the setup; the 5700 can't take 4S, and running it 2s makes it even less efficient.

You might like symmetry, but using two 1/10th scale systems is quite a missfit IMO..

Unless someone has a better suggestion, I'm going to have to agree with procharged5.0.

0700 05.23.2007 03:50 PM

Serum, wouldn't a pair of these or 6900s on #S get the job done with two smaller motors...I guess one big motor on 4S would be more efficient, thanks for your patience....

Serum 05.23.2007 03:57 PM

You could use two small motors on 4S as well, which makes it more efficient. np on the patience, i am just no fan of the tiny-micro rotors that are in the mm motors. even two are not enough. a wanderer/feigao S motor delivers more torque.

But if money is an issue and you can agree with a huge compromise you could set for the dual mm setup..

It's not my advice though.

Or two MM controllers and two basic XL motors.. One basic XL motor (2400) on 3S lipo delivers impressive power in a 7lbs heavy maxx.

So the Lehner 10th scale motors are just better than the Mamba 10th scale?

0700 05.23.2007 04:21 PM

BTW what do you think of that outrunner setup on ebay?

Serum 05.23.2007 04:32 PM

Yes, they use segmented magnets, but Neu is my favorite over Lehner.

that outrunner; i wonder what it does in real life, (how hot it gets etc) because an outrunner is meant for a fixed RPM, and not for a constant variation in rpm's. the moving mass is located rather far from the center, which makes them less ideal to respond fast to the vehicles behavior.

0700 05.23.2007 04:46 PM

That's good info :028:

got a link to neu 10th scale cans?
