SUMMARY
The build quality on this ARF is superb, and its
airframe is much stronger than the standard
laser-cut built models I have seen. Lots of
interlocking structures help to provide the
rigidity. The covering is well-done, too, and
you’ll want to pick up the optional Detail
Upgrade Package, as it adds the required finishing touches that enhance the Nieuport 28’s
overall appeal.

esigned by Gustave Delage and built by Nieuport, the
N.28C-1 first flew on June 14, 1917, and entered service in
March 1918. It was designed to replace its various
Nieuport predecessors, but it, too, was already outdated before it
entered service.
However, the American Expeditionary Forces (AEF) of the U.S.
Army Air Service desperately needed fighters, and with the unavailability of new French SPAD S.XIII because of a lack of engines, the
AEF accepted 297 Nieuport 28s into service until the SPADs arrived.
The Nieuport 28 was a highly maneuverable and easy-to-fly fighter,
but had an unreliable Gnome 9-N rotary engine, and its performance
against the Albatros D.III and later German fighters was lackluster.
It also had a problem with its wings’ covering ballooning and
detaching from its plywood structure, but that
was soon remedied. It served with the AEF for
only five months before being replaced by the
SPADs.
However, a few U.S. aces got their starts and
some of their initial victories in the 28, including the U.S.’s top WWI ace Capt. Eddie
Rickenbacker of the 94th Aero Squadron, a.k.a.
“Hat in the Ring” squadron, who’s Nieuport
this model resembles.
Maxford USA’s 1/8 scale N.28C-1 is a solidly
built model that consists of lite ply and balsa
structure that is pre-covered. When I looked
inside of the fuselage to check out the build
integrity, I was reminded of the old days and
how models used to be built. From the forward
fuselage all the way to its aft section, this
model is solidly built. When the time comes,
the “beefed up” forward section will help in
balancing the model.
The fuselage, wings and tail surfaces are
jig-assembled from laser-cut balsa and plywood and pre-covered,
with precut hinge slots and CA hinges with pre-punched pinholes
for alignment. The box also contains prefinished cabane and interplane struts, a full set of insignia and marking decals, windshield,
pre-painted fiberglass cowl and plastic headrest and rigging wires.
The extensive hardware package includes everything required to
setup the aileron, rudder and elevator pushrods and linkages, preformed main landing gear with rubber wheels, a steerable tailwheel assembly, and pre-painted and -installed wooden fairings.
hook and loop battery-strap material and all the other required
hardware to complete the model. A detailed and illustrated
instruction manual rounds out the box’s contents.

much appreciated by the builder.
When mounting the elevator and rudder servos, connect their respective
arms to their pushrods and then place
the arm on the servo. With this connection, allow each servo to find its “place”
in between the servo rails and then
attach them with the screws that come
with the servos. I used Hitec’s HS-55s,
which fit perfectly between the rails.

the alignment perfect when placing these
items. Before the cowl is attached, cut the
battery’s hook and loop straps and place
them in their respective holes. To mate
these pieces, it helps to use two ball drivers to reach through the open firewall
holes and press the straps together.

venturi and the decals and the assembly
portion is finished. The next step is balancing the model, and the manual says that
31/2-inches back from the top wing’s leading edge is the spot. Using a heavier
Thunder Power battery pack that weighed
6.2 ounces, I used 3 additional ounces of
stick-on weights to achieve a level-looking
balance. Another way to balance the model
is to turn it upside down and place your
fingers on the most forward portion of the
bottom wing’s leading edge. If the model
hangs level, then it is good to go.
When I set the control throws, I added 25
percent expo on all high rates and 20 percent on the low ones. The aforementioned
addendum includes inches of movement
for all control surfaces.
CONCLUSION
Although a couple of items need to be
thought of in a different way during the
assembly process, overall, I found the
Nieuport easy to put together. Read over
that manual a few times before you dive
into the building process, as it will help
you to understand how things go together,
especially where the wings’ flying wires
are concerned. Once it’s properly balanced,
it’s a nice flying WWI model that Maxford
