“Adding an Extra 330S to the Performance Series was a natural. For sport flying, precision aerobatics, or 3D, our
Extra 330S delivers!“

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 thatfs reinforced with balsa sheeting. |

|
| 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! |
|
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. |
|
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. |

|
| 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. |
|
The tail gangs two rudder servos in a pull/pull set-up that increases control precision. Itfs one of numerous design elements that combine to give this model the ability to execute any current 3D maneuver to perfection. |
|
Many ARFs come with such unreliable hardware that most modelers wouldn't dream of using it. Some donft include 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 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. |
|
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. |
|
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 modelfs orientation during maneuvers. |

| 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 enginefs 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 modelfs potential by keeping weight low while supplying excellent power. |
|
The composite landing gear offers smooth contours that perfectly complement the modelfs scale looks — and provides the strength and reliability needed for confident touchdowns.
