One year, the kit apparently included FP motors rated at 6 volts. At 12 volts they apparently had ridiculous power (~400watts) but they also had a nasty habit of dying frequently.

That year was awesome. And you're right- they were about 100 watts at 6 volts. Doubling voltage quadrupled power for brief excursions to around 400 watts. If you were lucky enough to have gotten those motors, and lucky enough not to have fried them, you could do a lot of interesting things with that much power in that small a can.

Most of the motors in FIRST have historically been sourced from automotive applications, so they are happiest at around 12 volts. Car charging systems not being the most precise things a lot of the motors are expected to have a fairly wide operating range before any problems arise.

The RS-775's are, I believe, originally made for a cordless drill. The upside of operating below it's design voltage for us is that, although they are a little weaker ounce for ounce, they have a more safety margin before frying then the 500 sized motors.
