wind controller [RE-wrenches]

All 4 of my personal Bergey 10's did great!  Not so much as a chip in the
paint.  Of course they were all in the shop in various stages of being
rebuilt!

I've personally watch sustained 80mph plus wind hit a Bergey 10 while it
simultaneously was struck by lighting and it never so much as skipped a
beat.  I also had a tornado hit 3 solar customers several years ago.  It
ripped all of the solar panels off of the racks and literally wrapped the
tracker around the tracker's pole.  It was ugly.

Ironically, the reason I have three of the four Bergey's is that a tornado
hit them (that same one that that hit the customer's in the above paragraph
but about 50 miles away).  They very likely would have survived had the
customer's hack dealer not elected to build custom towers which where too
wide at the top this allowing the blades to deflect into the tower and
whamo!

Travis--
Glad your intact !

So what happens to a turbine, small or large, when a F3 + passes thru?
