No problem.

Regarding the motor - that sounds like a pretty big one, are you sure
those ratings are foot-pounds and not inch-pounds? Also, were both the
6 ft-lb and 30 ft-lb numbers specified, or did you multiply the
continuous rating by 5 to get the peak? The reason I ask is that you
should probably be conservative if you're estimating I'd multiply a
continuous rating by 4 (or maybe 3) to get peak, or divide a peak rating
by 5 (assuming that people who only quote peak ratings are hiding
something :) )
