what effect, if any, they would have on the high and low
speed characteristics of any of the Lancairs."



A neighbor of mine who has a flying 360 recently installed
vortex generators on his wings. Here is his statement:

I installed a vortex generator kit on my Lancair 360 in July
2003 supplied
by NorthWest Aero in Bend Or. the kit was designed
specifically for the
Lancair 360 and installation was straight forward except for
one small
detail: the layout geometry was presented for an extended
wing tip mod and
my aircraft was built with the standard kit wing. This was
not a problem
once I figured out what was going on.
The resulting flight characteristics were very positive:
Reduced stall speed by a full 10 knots
Much better roll control at low speed
Use of 10 degree flap instead of 40 degree for landing with
a more
comfortable sink rate on approach
No noticeable change in handling or air speed at the top
end of the speed
range.
The final numbers after testing per FAR 91.319(b) are
nothing short of amazing.
