REFLECTOR: VG

[Stockman, Bill]

I've flown with and without them on my 173FGE and they make a difference, I also added trailing edge fences and they make a difference.    With both, I can put the plane into 2000 ft runways or clear trees.    I flew for ten years out of Moraine airpark in Dayton which is short, 20 ft river levees at both ends and 75 ft  mature trees-the velocity handled all with great ease.    The trick was learning to slow down on the approach and landing.    Anyone can fly fast, but learning to slow down on final is a must and the VGs and fences help a lot-especially for those of us who don't have those big MT rotating speed brakes.

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

I have CC I vg's on my plane. They are OK. They are sharp and care must be used when washing the plane. They also get brittle over time, they are not UV proof as advertised.

  I was looking at Velocity's store web site and they didn't have the VG for the wings and canard. I found a place called CCI of New Jersey has any body used their VGs?
