Bill brings up a very good point concerning adjustable propellers.  Steve
Parkman of SWAG using a Geo Metro engine in a Long EZ, among other things,
apparently set the adjustable propeller to give maximum static thrust.  It
was reported that the manufacture of that prop estimated that with those
propeller settings, it was unlikely Steve could have reached a speed much
higher than the mid 70 mph range.  Steve apparently never got much out of
ground effect before the crash and fire. Just another thing to consider.
