The Redwing RC 50cc Extra 330SC is ready for its first flight.
Its color scheme is bright and easy to see.
Redwing RC is based in Ballwin, Missouri, which is a suburb of St. Louis. The company has a variety of
aircraft available ranging in size from 20cc
to 100cc, as well as engines and a large
number of RC accessories. Redwing RC’s
50cc Extra 330SC is available in several
color schemes, including an an all-white
The airplane is reasonably priced and
Redwing RC offers inexpensive flat-rate
shipping. The airplane arrived in one large
box that measured 14 x 22 x 67 inches. The
contents were well protected and in perfect
condition. The PTE 72 engine was shipped
in a separate box, and it also arrived
without any damage.
The fiberglass cowling is nicely made and
the paint looks fantastic. The kit includes
carbon-fiber landing gear, a tail wheel
bracket, a wing tube, a tail tube, and bolton servo arms. The preinstalled canopy
requires no assembly.
All control surfaces are predrilled for the
point-style hinges. The rudder pull-pull
cables are preinstalled in the fuselage and
the fuel tank is preplumbed. The assembly
manual comes on a CD and covers the
assembly of several Redwing RC aircraft.
The construction begins with the
installation of the prepainted composite
control horns. The slots for the
preassembled control horns are precut in
the control surfaces. The control horns
come with the ball link conveniently bolted
in place. The control horns and hinges are
glued in place with 30-minute epoxy. I
used 1-inch-wide strips of clear UltraCote
covering to seal the bottom hinge line on
the ailerons and elevators.
I bolted the landing gear and tail wheel
assembly into place on the fuselage. I
secured the landing gear cuffs with GOOP
contact adhesive, and masking tape held
the cuffs in place until the adhesive cured.
The next steps in the assembly were the
installation of the axles, wheels, and wheel
The Extra was now ready for its
electronics to be installed. Airtronics
94780M metal gear digital servos with
SWB Manufacturing servo arms were used
