Good question, Lynn.  You're correct, but unless the prop has a pitch 
indicator--most NSI units don't-- one sets it by a simple process prior to 
takeoff, but sometimes it needs a bit of a tweak during the takeoff process 
to get the correct takeoff rpm.  Not a big deal at all, but for someone who 
hadn't used one previously, it could be.  Again, it's just speculation.  I 
have no idea what actually happened.  As for the prop going into reverse, I 
doubt it.  That prop has built in interlocks so that it cannot go into beta 
above a certain rpm.  I think it's about 1200 prop rpm to be exact, but I'd 
have to check.
