Which ESC/MOTORS FOR A ROBOT!!

[nbcaznmaster]

The robot is actually going to be for a competition where ping pong balls are going to be distributed into corners of a small track. The goal is not going to be torque but speed. The esc's are now http://www2.towerhobbies.com/cgi-bin...?&I=LXD523&P=6 with http://www2.towerhobbies.com/cgi-bin...?&I=LXJBY4&P=7 for the motors. There will be 2 ESC's controlled by a PIC microcontroller board, one for each motor. I don't actually know what the final weight is going to be but it will likely be around 7 pounds. This is not going to be remote controller, it's going to be autonomous (self-controlled). BTW, this is his brother.
