88.3[rev/s]/12.75/1.4*0.5*3.14[ft/rev] = 7.77ft/s maximum top speed assuming no load, which of course is a bad assumption, so your real top speed will be a little lower. Quick, but not insanely fast.
Ya that makes more sense...We did this after we found 31fps untrue, and we got the same result.

But that still dosent explain how it moves faster that that.....Ill put up a video as soon as it is emailed to me
