Re: REFLECTOR:Vortex Generators on XLThat is another nice thing about =
the VG's  They help keep the air attached to the top of the canard at =
low speed which also improves the airflow through the elevator slot. =20

Jim White used to cuss cause he had a hard time controlling the nose =
gear "crash".  After the VG's he says it is much easier to put the nose =
down softly.  Same here with my 173.

  Mack,
  I sort of just get it to the runway and it touches down when it is =
good and ready. Sometimes nice and easy and sometimes not so easy. Seem =
that if I try and slow it up the nose rotates down a little too fast =
where if the speed is up I can carry the nose gear up half way down the =
runway and touch it down when I want.
  You are right I don't know what speed that is. Too busy enjoying the =
ride
  Jack
