    And I always thought Miami and Orlando were actually in Florida. 
    Who knew?

    Yeah, Rob is correct.  When
      we arrived at the field for the contest in January 2010, there was
      frost on the grass!  For those who don't know Florida, it's just
      south of Orlando and about 200 miles north of Miami.
      

      
      We (me especially) had problems with cold batteries.

                    Cold?  What's that?  Oh yeah, I have dim memory of
                    that sensation.

                                Hi Bob,
                                 
                                Could it be that
                                  your battery was just too cold?
                                I've had that
                                  happen.
                                As the season
                                  progresses and our batteries get a lot
                                  of use, and they, like us, get a
                                  little tired from time to titme.
                                 
                                If that happens
                                  again unplug the battery wait a minute
                                  or two and plug it in again.
                                When I've done
                                  that it goes back to one beep.
                                I warm it up a
                                  little and fly my whole sequence.

                                                          work OK.  I
                                                          was
                                                          practicing(!)
                                                          some maneuvers repeatedly
                                                          and the pack
                                                          quit
                                                          unexpectedly
                                                          again, but it
                                                          may have been
                                                          my fault for
                                                          not paying
                                                          attention to
                                                          the flight
                                                          time.

                                                          failure?  The
                                                          pack has maybe
                                                          30 cycles on

                                                          but this pack
                                                          is rock solid.
                                                            The pack is
