E-Maxx/Revo dual motor question

[SketchyRC]

Hello I have been looking at Traxxas E-Maxxes and Revos recently. I found it so cool how the brushed versions had two motors! But I didn't care for the more expensive momba whatevers. Which brings me to my question. Why don't I ever see dual brushless motor systems in them? My reason for this is that if I could upgrade one of these to a brushless motor system (preferably Traxxas's Velineon system) and still have dual motors I would do it in a heart beat. I just think it would be so cool! So why have I never seen something like this? Is it possible? What would I need to do it?

One mamba has the power of two velineons. But if you want two Velineons, you have to have a dual motor plate. There are youtube videos on it so it is possible.

Correct. Velineon are, but make sure your batteries are WP too.
