You shouldn't be using SPIKE relays to power the motors. The KOP (Kit of Parts) includes two Jaguar motor controllers, which use a scaled PWM input to turn the motors anywhere from +1.0 (full forward) to -1.0 (full reverse). Should you find that you require more than these two, additional Jaguars are available for purchase by FIRST teams @

Victor motor controllers are also an option, which provide similar functionality, but are not included in the KOP.
Both of these can be easily implemented in LabView. In fact, I think two are implemented in the default code. All you have to do is select which PWM channel they are using on the digital sidecar (typically 1 and 2).
As a team sponsor, we are more concerned with the behavior, attitude and commitment to FIRST ideals than specific performance in the competition. Some of our teams perform well, some struggle, some are in the middle. We support them all in every way we can. - Chris Fultz [more]
