>From Karl, N7MXO, he posted this and it didn't get to
the list.   I am fwding to the list at his request. 
I'll add to Karl's advice- fly with an radio
operator/spotter.  "Fly the plane first!" is always
good advice.  Doesn't take too long to get into
trouble if the PIC is button pushing on D7 & GPS.
