L'Extra 330SC è l'ultima novità della linea di Walter Extra Flugzeugbau in Germania.

Si basa sull'Extra 300S di grande successo e incorpora tutte le piccole modifiche apportate al 300S nel tempo, come un motore più potente, superfici di controbilanciamento più grandi sugli elevatori e alettoni e molti altri piccoli aggiornamenti.

Soprattutto, la 330SC ha ricevuto una nuova cappotta molto più aerodinamica, montando anche uno spinner più grande e appuntito. Tutto sommato queste modifiche hanno migliorato notevolmente le linee dell'aereo, ma soprattutto, le prestazioni.

Noi modellisti notiamo immediatamente che tutte le modifiche alle dimensioni complete apportate a questo 330SC lo renderanno sicuramente un modello migliore anche per un aeroplano.

Il percorso verso superfici di controllo più grandi, maggiori controbilanci, linee più snelle e altre parti aerodinamiche, ci era stato negato per anni, per non dire decenni.

Quindi, in altre parole, il 330SC è esattamente quello che noi piloti acrobatici abbiamo sempre desiderato.

CARF-Models ha quindi preso in considerazione tutto quanto sopra, e ha aggiunto alcune delle ultime tecnologie di produzione composita, per rendere questo nuovo 3.1mt il migliore Extra mai costruito.

Lasciati conquistare.

Il miglior Extra di tutti i tempi è persino migliorato! Sarà la tua ammiraglia dei sogni della stagione.

La particolarità delle ali Extra 330SC da 3,1 m sono gli alettoni incernierati separati centrali.

A differenza dei più piccoli piani acrobatici dei modelli CARF, la penalizzazione del peso non fa meno male, quindi i vantaggi superano di gran lunga gli svantaggi su un aeroplano di oltre 3 metri.

Ma non solo CARF Extra 330SC presenta i nuovi alettoni incernierati centrali con contrappesi, abbiamo ridisegnato il sistema di cerniere in modo che l'alettone diventi molto più leggero. Il lungo e pesante perno della cerniera non è più necessario, il che elimina anche il rumore dovuto alle vibrazioni. Una nuova geometria dell'ala si adatterà meglio alla fusoliera allungata dell'8% e darà l'apertura alare effettiva di 3.1m (122 ")  rendendola ancora più leggera nelle manovre 3D. 

 

Stabs

The elevators have received full size counter balances. The rudder trailing edge has been widened to a massive 8 mm, creating much better slow flight and high alpha characteristics, at the same time, provides smoother reactions at high speeds, without reducing the impressive rudder authority. We prepare each stab and elevator for the possible upgrade to two servos, but do only install one set of control horns. The very powerful HV servos today provide sufficient torque and precision. However, if a 4-cyl engine is used, the additional weight of a second elevator servo per half will not be a problem.

    

Fuselage

The fuselage of the CARF Extra 330SC 3.1m has initially been created for our first Extra 330S in 1999, then evolved into the very popular SuperXtra, got stretched once more and structurally redesigned, and resulted in our newest Extra 30SC fuselage with the very short canopy and improved rudder/fin geometry. Very high attention was placed in the landing gear mount, being reinforced and redesigned quite a few times, resulting now in our strongest gear mount ever installed in a 40% aerobatic airplane. The fuselage has longitudinal stiffeners along the sides, a crucial reinforcement former in the rudder fin and an all carbon reinforced motordome area. Fuel tank mounts, rudder servo mounts are CNC milled, included but not installed, to give everybody the freedom to either install it our way, or follow their own preference as they like. There is enough room to install either canisters or full length pipes, as long as a large venting hole at the bottom fuselage is cut and reinforced, to prevent electrical equipment from overheating. Structurally the fuselage material will take any possible muffler heat easily without damage or fatique.

 

Cowling

The new style, two-part cowling is large, gives room for any 170 cc twin cylinder engine as well as 200-220 cc four cylinder engines, since the motordome of the fuselage is short enough. An adapter is included to fit the shorter 2 cyl. Engines easily. This adapter allows the mounting of a 2-cyl engine with long M6 bolts to still anchor the load in the main firewall. There is plenty of space for all types of headers in order to install either full length tuned pipes or canisters. Cylinder-mounted mufflers have also enough room under the cowl. The cowling has the front face towards the spinner backplate perfectly aligned so that the correct thrust lines have to be copied from this front face. Tested in many airplanes and setups, these thrust lines are right and will not need adjustments during your first trim flights. the two-part design allows the top cowl to be removed without removing prop and spinner, making it easily accessible for way-forward mounted batteries in case you prefer to fly the plane quite nose heavy with a 2 cyl. engine installed.

   

Landing Gear

The landing gear does not only come with streamlined wheel pants, but also with production style gear cuffs, to make the appearance more scale like. The thickness of the gear leg has been adjusted several times to create the correct "spring dampening" at the anticipated weight of this aircraft to protect the carbon/plywood mount in the fuselage from damage during less than perfect landings or bumpy grass fields. However, they just have the needed stiffness to have the plane sit right on the runway during taxi, take-off and landing.

   

Flying Performance

Intensive discussions with our customers, contest pilots and team members, have revealed that the recipe for success would be literally the combination of two worlds. In one way, it should satisfy the most scrutinizing contest pilot in the way it flies, but also look like the full scale aircraft without silly alterations. In the other way, it needed to allow at a defined CG setting, weirdest and most extreme freestyle maneouvers and at the same time, with a more conservative CG setting, without further modifications, allow smooth and predictable sequence flying in top class contests. 

A candid tail moment and large control surfaces sign responsible for the high agility in 3D flying. Yet for sequence flying the tail moment is just right, too, to track perfectly and still show the break in snaps as the judges want to see it. The ailerons are perfectly sized. They allow incredible roll rates with only two servos, but are not too large to still allow precise sequence flying. Due to the fine tuned airfoil and the little mass in the outer wing areas the 330SC snaps crisp and stops predictably. The wide rudder trailing edge increases precision and stability in fast flight and smoothness in 3D high alpha maneuvers. Only very little knife edge coupling needs to be compensated. 

The CARF-Models Extra 330SC is a perfect aerobatic machine, giving the contest pilot everything he needs for freestyle and sequence. A strong and rigid model by design and build, lasting many contest seasons if maintained properly. A robust yet precise training tool for all of you who want to become masters of their class. A beautiful machine to run high on emotions and enjoy your hobby like never before.
