OK, let's address them.
.....The fact
is that I just came back from factory flight training in the SQ2000
and consistently touched down at about 90mph and took off about 90+.
If this is what they're teaching you at the factory, then they're doing
their builders a disservice.
It is a faster, somewhat heavier aircraft (gross 2250) with about a
28' wingspan. The CG was in the middle and weight was not anywhere
maxed out.
I have landed my COZY MKIV at extreme forward CG position at a gross
weight of 2150 lb. The fastest I will touch down is about 85 mph in that
configuration. As Richard has pointed out, 75 mph touchdown speeds are
closer to the norm, and is what I was taught when getting checked out in
other COZY's. I have about 160 hours and 300 or so landings in my
plane - I have NEVER felt the need to come in any faster, even in a 15
kt. crosswind with 5-10 kt. gusts.
.....A Velocity has about 30' wing span giving it the extra lift
at slower speed but pays the cost at high end - unless you have 300hp.
But no one was discussing Velocitys. Richard clearly pointed out the
comparison to the COZY MKIV, which the SQ-2000 bears the most
resemblance to, from a size, weight, and power standpoint.
While its possible to land a canard slow, its not as stable and a
number of canard flyers will land at higher speed in order to see the
runway.
Well, I don't know where you're getting your information, because the
three COZY's I've flown as PIC (from both right and left seat) have had
no "stability" issue whatsoever at touchdown speeds down to 70 mph (or
even 65 mph, with rearmost CG and light weight). Almost all the L.E. and
V.E. folks I know also land in the 70-80 mph range, at the most. As long
as I keep the canard on or below the horizon, I can land at these
speeds, see the runway, and have no stability issues.
Anyone landing faster than that is doing so because they do not know how
to correctly land a canard aircraft. I'd like to see you land a SQ-2000
(or a COZY) on a 2500 ft. runway, touching down at 90 mph. I have no
problem doing it in my plane, using slower speeds, even in relatively
strong crosswinds, and at high weights.
Tell you what, Paul - I'm not interested in a ****ing contest - I'm
interested in safety. I'll be happy to check you out in my COZY MKIV
(left seat, if you'd like) if you'd like to come to MA before your first
flight, so you can see the difference. Let me know.
