Mambamax pro on Revo?

[BrianG]

You are right, but the MMPro BEC tends to be on the weaker side. I have several here and the ones I tested cut out when the load exceeded ~2A. Even before 2A, the voltage dropped more than I would like. A 3A external BEC would be a better choice if using the Pro on a larger scale vehicle, particularly on a MT where turning is quite high with those big tires.

As far as current-handling goes, I would rate the MMPro a little above that of a MM, but less than a MMM. Again, being in a Revo, I would still watch temps for a while to make sure it's not being stressed.
