Bob,
Does the decrease of 5 mph stall speed translate into a real decrease in
touchdown speed and did you install the VG's or did you have that done? I am
interested in seeing these.

Hello, has anyone had positive results(reduction in stall speed) using
vortex generators on a wing utilizing the RAF48 airfoil?

Thanks,
David

I don't know the numbers for my RV-4 airfoil,but my vortex generator
installation has lowered the stall speed 6 - 8 MPH,as near as I can
tell so far.
I like them .
