Our team once blew out two Victors simultaneously due to an error made by an inexperienced person who decided to re-wire the entire robot late at night for no good reason. Suffice it to say that connecting supply leads from a breaker panel to the output terminals of a Victor 883 results in the magic smoke leaking out faster than those present previously thought possible. Since then, we've been very cautious about our speed controller wiring, and haven't had any further problems. If you're using 5 on your robot, though, that increases the odds that you will suffer some sort of catastrophic failure that will necessitate hardware replacement. The spare parts available at FIRST competitions have helped us in the past when we were facing the very real possibility of shoving a non-functional hunk of wires and Lexan onto the field, but it's much nicer to have your own spares on hand.
