I have a converted Revo 3.3 (MMM/1515 2.5D), and now the Flux. Keep in mind, I've run that Revo for 3 years, and only one run on the Flux up and down our street for about 15 minutes.
Revo outhandles the flux. Period. Not even a comparison.
Flux is too short/narrow as it sits out ouf the box, especially if you are going to run 6S. On 4S, it might be a better match.
I fight the Revo suspension sag all the time - I may have finally nailed it this summer.
Flux seems fairly well balanced right now - but will have to do some jumping with it to really know.

I dont feel that they are really a comparable truck though. A Flux will never handle like the Revo, thus you'd likely never race a Flux. You can bash them both, like you can any truck. And like any truck, depending on how the stars align for you, and which rock gets in your way, you can break any of them. And with ANY rig, you are going to break your drivetrain trying to do backflips.

My guess is that if the economy doesn't completely tank, there will be a better rig on the market in a year. But then, by then I will have likely spent another couple hundred upgrading and fixing this truck, having fun the whole time!
