MULTIPLEX EXTRA 330 SC GB
I tested the receiver-ready
version of this model, which
comes with all hinges installed
except the rudder. Hinging the
rudder requires that you simply
snap it to the vertical stabilizer’s
hinge halves. When the two make
positive contact, there will be a
definite click. Mine fit together
flawlessly, and the result is a
smooth-operating control surface
that can be easily removed if
needed. The other hinges are wide,
flat plastic CA types with four per
aileron and four on the horizontal
stabilizer/elevator. The tug test
verified that all were glued in well
at the factory. Control connections
are completed with long servo
arms, metal rods, and double
plastic control horns, all of which
were factory positioned, glued,
and ready for final adjustment.
Setscrews make setup a breeze.
With power on and all controls at
neutral, you can quickly and easily
position your surfaces by hand
and tighten up the screws. Adding
a drop of blue thread-locker to the
screws doesn’t hurt.
The landing gear looks super
cool and is made out of carbon
fiber. It arrives as a complete
unit with mating undercarriage
fairings/cuffs, foam wheels,
and plastic wheel pants all
preassembled. Two larger-gauge
hex-head fasteners anchor it to
the fuselage. For the tail gear, a
bent wire and a foam tire keep
the rudder from dragging on
terra firma. All airframe parts fit
together with tight tolerances.
The wings are two parts, which
are reinforced with more carbon
fiber. A carbon-fiber-reinforced
polymer wing tube keeps the
wing halves lined up and from
doing the “taco.” It’s probably
worth mentioning that each
aileron/counterbalance makes up
more than a third of each wing!
A similar stabilizer tube is also
employed, while a plastic screw
secures the horizontal tail in place.
Rather than using the supplied
screw, I glued my stabilizer to the
fuselage, as I have no intentions of
disassembling this model.
The fuselage has a large hatch,
held in place with magnets and a
mechanical latch. A tinted “glass”
cockpit shows off a preplaced pilot
bust and dashboard with flight
instruments/gauges at the ready.
The factory-applied decal design
is stunning; a big thanks goes out
to the designer and applicator.
For power (thrust for 3D), there is
already a motor and speed control
installed. Check the supplied
propeller for balance, install it, and
screw on the supplied spinner. The
sample prop was well balanced out
of the box.

Short grass is good, and a paved
runway is ideal. Hardly any room
is needed; you could fly this
plane in a park baseball diamond.
Depending on your flying style
or frame of mind, this plane can
do a scale takeoff as smooth as
silk or you can pull up and go into
an “afterburner”-type vertical
climbout. The thrust generated
by the Permax power system
pulls the plane up in a hurry, so
hardly any rudder correction is
need during the rollout. Landings
are almost as easy. Keep the prop
turning and wings level while using
Carbon-fiber landing gear offers solid ground handling. Plywood reinforcements and Hitec metal gear servos keep this plane solid in flight.
Gernot, is that you in there? The included pilot bust is ready for action.
A push-pull rudder system is employed. The tail wheel works well making taxiing
an easy task.
Short and simple, the linkages are easy to set up and adjust.
