I currently have an MMP. I have run an RS PRO, & Revneton pro. The reventon was BY FAR the smoothest & easiest to drive, but that was also because it had the least power. The RS PRO was my favorite, but was no where near as smooth as the rev. The MMP is my least favorite. It is smoother than the RS PRO but not as smooth as the rev. The power is about equivalent to the rev. It gets hotter, the motor gets hotter, & I don't get as much run time (13 minutes vs. 20+ minutes). If you have an MMP it will be fine till you can save up for something else. If you are spending $, get something else.

I WILL be getting the RSX in the very near future. I have driven the rs gen 2 & the rx8 gen 2. Both of them are much smoother. At least as smooth as the rev pro was if not more so. I usually won't recommend an ESC with out owning it or spending a lot of time with it, but with the RSX, I will recommend it now!
