Re: Spark Motor Controller vs. Victor SP

Well this is a silly debate to have, but here goes.

All motor controllers and everything else sold to FIRST teams is based on the unit weight, as it is impossible to figure out everything that attaches to it.

Does the Cross the Road published weight for the Power distribution board take into account all of the wires or the fuses that could be plugged into it? How about the VRM, Pneumatic module, etc? Also when the spec sheets were made for the victor 884/888 or talon SR or Jaguar what length of wire was included in the weight?

For that matter what gauge wire are we talking about, not every motor needs 12awg, so in situations where smaller gauge wire is used, it would change the unit weight.


To teams reading this: We do our best to provide the best documentation and information that we can. If there is something that you would like clarified or anything missing, please feel free to ask.
