Re: 4W Maximum Power Servos? Huh?

Servocity.com gives you ounce-inches of torque, and seconds to turn 60 degrees. A little conversion gives us:

Power = 0.25 * oz-in * (0.00706 N-m/oz-in) * (1/(6 * t)) RPS * (2pi rads/R)

Or,

Power = 0.001849 * oz-in / (sec per 60 deg)

Judging by that, there aren't many servos on ServoCity that AREN'T legal. So I'm doubting that's right. I think the electrical load is the more likely definition, though that's more difficult to determine, since there's less specs on that.

All in all, probably a good Q&A to see if the GDC was thinking electrical or mechanical power there.
