wing is an almost laminar flow wing, and the center of lift
of the wing is further aft. The forward move of the wing
almost balances the aft move of the centre of lift to the point
that the wing is very close to the standard wing in regards
to passenger and baggage loads.
On take off the wing will provide more lift earlier than
a standard wing and breaks the ground earlier. The climb
to altitude will be similar to a standard wing. Speeds at
lower altitudes are the equal to the standard wing but it
is faster at higher altitudes. I do not yet have all of the
flap hinge fairing installed , but I do believe the plane will
be at least five knots faster at high altitude cruise speeds.
The stall speed is where this wing really shines, in that it is
between five and ten knots lower than with the standard
wing. Not only that, but the wing has noticeable ground
effect after the flare and this allows more consistent landings
and much shorter landing rolls. On my grass strip
this is a most welcome improvement.
The roll feel is a bit heavier and the rate of roll is also
reduced due to the increased wing span. The wing has
neutral stability in the roll axis and the plane will stay in
the roll attitude that it is left at. The wing is much more
stable in roll than is the standard wing, so much so that
my wife is enjoying the ride. She suffers from nausea

and with this airplane I find her looking for places that
we can go together. This greatly increases the value of the
aircraft from our family’s perspective! Aileron trim is not
required with this wing and a curious feature is that you
do not notice fuel imbalances in the wings the same as
you do with the standard wing. This is apparently due to
the increased stability of tapered wings in general. Pitch
forces are perfect for the aircraft and tend to lighten up
considerably with aft loading. From a pilots perspective
the flight “feel” is not better or worse than the standard
wing, just different.
To date I have been all over southern Ontario, the Geneseo
Airshow, AirVenture and a trip to Chesapeake Bay
in Maryland and I can say that this wing offers a definite
advantage for cross country flying. The increase in roll
stability, even in rough air, greatly reduces the fatigue of
longer flights.
I have enjoyed the building process with this new wing
and the flight characteristics have made it a good choice
for this fuselage. Another benefit is that with the tapered
wing it is no longer called, by default, an RV something.
Although I have nothing but good things to say about the
RV product line it is nice to not be just another one of 5000
flying aircraft.
