I certainly agree with John's comments.  But the = 65 knot quoted stall speed seems a bit low, unless the speed is for a lower= -than-gross weight or is an indicated airspeed.  My only reason for th= e comment is to caution others against assuming the stall speed is really t= hat low.  In my opinion exploring the stall characteristics is for a t= est pilot, but then I'm a real chicken pilot. :-).  If I had reason to= be suspicious of the stall characteristics of a prospective IV acquisition= , I'd hire a test pilot to do the evaluation.  But that's just me - ot= hers might be bolder.
