Re: Spark Motor Controller vs. Victor SP

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.
Greg,

Why is this a silly debate? You have information on your web site that does not include key information. I can only guess that it is an oversight on your part. You know as well as I do that the apples to apples comparison is to compare either with, or without, wires.

We have done this on the VEXpro web site for our speed controllers. For those that are interested, here is the data:

Weight:
Victor SP w/o wires - .16 lbs
Wire weight - .07 lbs
Victor SP with wires - .23 lbs

To claim that your data in the table is not misleading potential customers is, well, misleading.

This is only my opinion, but I take issue with you stating the debate is silly because it is not. Some customers just take these tables at face value and you know it.

Paul
