REFLECTOR: VG

[Peter Braswell]

All,
The VG's seem to be a bit of a pain to deal with.  I was wondering about
the tangible benefit they provide and are they worth the heart burn?

I had VG's on my Glastar.  They were however just triangular shaped devices
that were mounted just above the airfoil out on the leading edge and they
roughly followed the curvature of the wing.  There were two on each wing,
one mounted about 3/4 outboard and the other right at the root.  They were
advertised to lower the stall speed and to help maintain aileron
effectiveness at low airspeeds.  I ended up removing the root mounted VG's
to better seal the wing root area (the cabin was drafty) and I didn't
notice one bit of difference in either handling or the stall speed.

Peter
