hardware at all. Great Planes provides a complete package of
well-made hardware that saves you from future shopping trips
and keeps your Extra 330S performing like a champion!.

The Extra 330S offers an ideal balance of low weight and high
structural integrity, both essential for performing high-stress 3D
maneuvers. The turtle deck is a good example — it's constructed of a
precisely sculpted foam shell thats reinforced with balsa sheeting.
This Extra 330S is engineered to perform IMAC competition maneuvers
with judge-pleasing precision and grace. Stable slow speed flight
characteristics also make it a good choice for fliers moving up from
smaller models like the .46-size U-Can-Do 3DTM.
The Extra 330S excels at traditional sport flying as well as demanding,
IMAC contest-worthy aerobatics. All of the control surfaces are
oversized to allow for aggressive 3D maneuvering. Control linkages
are short, direct, and dependable.
The fiberglass cowl and wheel pants — painted to match the surrounding
Top Flite® MonoKote® trim scheme — add to the scale-like looks.
Great Planes does the work...but you enjoy all the compliments!
Helping to make assembly quick and hassle-free, the radio
compartment offers a spacious amount of room for easy
installation of your receiver and other on-board components
The composite landing gear offers smooth contours that
perfectly complement the model's scale looks — and provides
the strength and reliability needed for confident touchdowns.
The 79.5" (2025 mm) span wing comes in two halves which are joined
with an aluminum tube. Easy to assemble, the wing panels attach quickly
to the fuselage. Wings detach for transportation in smaller vehicles.
From every angle, the Great Planes 27% Extra 330S ARF is a stunner!
Distinctively different factory-applied trim schemes on the top and bottom
make it easy to follow the model's orientation during maneuvers.
The tail gangs two rudder servos in a pull/pull set-up that increases control
precision. It's one of numerous design elements that combine to give this
model the ability to execute any current 3D maneuver to perfection.
For gasoline engine power, Great Planes gives the Fuji-Imvac(TM)
BT-43EI 2 the "thumbs up". It has been extensively tested in the Extra
330S and passed with flying colors. The engine's Electronic Ignition
System offers easy starts and reduces weight and vibration.
An ideal glow engine match is the O.S.® 1.60 FX 2-stroke, which has also
been successfully tested in the model. It helps maximize the model's
potential by keeping weight low while supplying excellent power.
At just over 1/4 scale, this Great Planes model recreates the exciting performance of
the original Extra 330S, in a large size that makes every maneuver a BIG event.
