FP ok to stall?

Just one man's opinion.

Seconded! You can't beat them for sheer power. Especially because you actually have the option of running them at 1/2 stall, even if it's not the best idea. You won't run a CIM at 1/2 stall for more than a few seconds before you trip a breaker.

That said, we're using an FP to hold up a ramp this year. We've currently settled on 25% speed as a semi-safe value. We tried 30%, but after a long session of unintentional idling in the pits, the motor was producing some distressing odors. In the interests of my sanity, the students backed it down to 25% and promised to not leave it idling in the pits.
