I am interested in replacing the vex motors on my robot with faster and stronger motors. Is this possible and can you use the vex microcontroller (all the same parts) with the new motors. Can you list the motors that would be optimal and a supplier?
There are no other motors compatible with the Vex Controller directly. You can use other motors with the Vex Controller but, you must use a speed controller between the Vex Controller and the motor. The Victor speed controllers (http://www.ifirobotics.com/speed-controller-selection-guide.shtml) are compatible with the Vex Controller. See post https://vexforum.com/t/victor-support/12293/1
