A capacitor would only cause a sluggish response if it were in series with the motor. In that case, the motor would at times see a reduced voltage as the capacitor charges, and at other times see a higher voltage then the victor is outputting as the capacitor discharges. It would have to be a very large capacitor to be noticible, which means that it would probably be of the electrolytic kind. And we all know how much they like reverse current when you try to drive backward! They are used on large motors, such as in Electric cars. Because the starting current on a large motor is so high, it can draw the supply voltage very low and give poor performance. A large capacitor (or several smaller ones) can be used in series with the motor to keep the voltage from dropping to severely under acceleration.

If the capacitor were in parallel, bridging the positive and negative terminal, the function would be to filter out all the noise that a motor produces. They are common on DC motors. Typically, they are very small, on the order of 1uf or smaller, and of a type that isn't harmed by reverse current. My guess is that most of the motors we use already have filters installed in side of the motor can. In any case, it doesn't matter because the Victors are not going to mind either way.
