Hi Paul,
Here are some pics of the Nemesis NXT rollout at
Mojave
today.

Now all we need is a turbo 3 rotor in one of these.

Wow that plane is beautiful.  The landing gear is great
also.
Elegant.
How
much does this plane weigh gross?

Doug


Don't know but since it is all carbon fiber my guess is
under
1000
pounds
empty
and and 1500 pounds gross. If you need a kit  you better
get your
order in
now
as no doubt the price will go way up as they start to
dominate the
Sportsman
class at Reno as they dominated the O-200 Formula 1 class
for the
last
ten
years.
They hope to race it a Reno this year with the special
dual turbo
Lycoming
built for them. Here are some pictures of the buck making
process
that
occurred
across the taxi way from my hangar. Jon Sharp the
engineer/designer
works
for
the Lockheed Skunk works and as access to everything from
wind
tunnels
to
the
largest super computers running 3D CFD.

Paul,
That's interesting, they make the fuselage with L and R
halves
rather
than
conventual top and bottom half - probably easier to
incorporate the
vertical
stabilizer, for kit manufacture.

Actually the vertical split has been more common in the
composite kits
()Pulsar, Glassair, Lancair etc the KIS with the horiz split
makes the
assy process less painful, but does compromise some of the
things
you would like to put in the fuselage shape,

Why do you need the NXT  - if you can truly put 900 hp in
a Lancair 4P you would wax him big time - no way does
he have less than half the flat plate drag of the lancair. The
game
is almost pure horsepower over flat plate drag, and the bigger
heavier 4P  would have an easier time in traffic,
C'mon! lets put up the rotary money and go! - Vance

You just got done telling me induced drag (HP) did not matter at
Reno.

I am guessing he will be twenty MPH faster than the Lancair.
Assuming of course they don't have engine problems. Jon Sharp
knows
exactly what he is doing.

Paul Lamar

Paul - Induced drag is only part of the total drag picture (HP) and
it
becomes almost insignificant at Reno speeds and wing loadings.
Form drag which is a function of frontal and surface area, and
parasitic inputs is the primary. The Lancair is bigger, but still
very
clean,
and those guys have been fine tuning the race for more than two
years. I too am very impressed with Jon, and he may well
qualify perhaps 10 mph faster, but I would bet even money
that he will be beaten by one of the Lancairs THIS year.
If you can get 900hp in the Lancair I think it would have
the NXT by about 15mph - If you can handle the cooling
drag - Vance


I don't see how you come up with those numbers. The Nem Next is a much
smaller airplane with less surface and frontal area. I also would not
be surprised if it did not also have a lower form drag C sub d. I am
sure
Jon tweaked it in a wind tunnel some place. I will also
bet it is a couple of hundred pounds lighter than a Lancair IV.
The Lancair Legacy may be another matter.

True it is a new airplane and that may be its down fall this year.

Paul Lamar


How about the Lancair Sentry.

Mark S.


I think you're right Paul, we have a Sentry in town here and it is a BIG
airplane. The NXT looks tiny in comparison.
