Jack-
Hope the full fences work out to be beneficial.
I put the TE fences on the VariEze when they were recommended after flying without them
for about 5 years.
I would certainly agree with the repored benefit on liftoff and approach speed in the VariEze.
They are off being painted right now and there is a difference.
In practice i have noticed how often i am not interested in being in the minimal speed range where
they have the most effect.
For example, in sporty landing conditions, i have learned to add about ten
mph to the final approach speed. That learning experience included making a short field landing
just for fun, with a cross wind over trees and buildings. Burble. Should have learned from experience on
that one from someone else's experience
And on a normal takeoff i put the elevator an inch low and let the
nose lift and the plane lift off when it is ready. The climbout speed is comfortable at about 150 mph.
I have noticed that if i pull the nose off 'early' and waddle through the acceleration,
that there is much less energy developed than i like.
I have also talked with folks that almost always do minimum speed takeoffs and landings
and 85 mph climbouts where the fences are of significant benefit.
And I believe that they are a benefit on approach and climbout
even though i don't always operate the plane at the slow end as much.
After painting the bird i made one flight without the vortelons. That was enough.
Good flying.
Bruce, thanks for the suggestion on returns, was bugging me too but didn't know the
complex solution
