This is an E-Revo that I built from the ground up and
ran maybe 10 minutes on the street, never off road, just in the circle as well as in the grass in the front yard.
This is the E-Revo brushless 2200kv Monster Mamba version.
The motor and esc I bought used on ebay, I have no way of telling how much they were used, but they run great and have not let me down.
I find this funny

He ran it for 10 minutes and it never let him down.
