I ran a axial .28rr in my truggy for a long time and it was fine. I know it ain't like a Picco but that is why I liked it. A bit soft on the bottom. I had a Picco P3 .28 at first and was WAY too much for my driving. Some people like all that down low power. I do not. I like a nice smooth powerband and not all the SNAP you get with some motors.
