* At this time we have two color schemes available for the Schwing Corsa, they are both the camo scheme in red or green.
Developed from the thoroughbred all-rounder, Schwing 88, the new Corsa version comes in at 108” (2.75M) and is even faster than its predecessor while remaining a very aerobatic sailplane. The added span and wing area improves the Corsa's ability to fly in lighter conditions and conversely you can ballast it up even more for those howling gales. The Corsa's price point makes it an ideal F3F practice plane, so you don’t have to risk your unobtainium Euro-moldie.
The Swing Corsa 108, has a higher aspect ratio, a further optimized wing plan form and uses the original, venerable wind tunnel tested airfoils. Slim yet practical, the layout provides enough volume to allow generous ballast in the fuselage as well as the wings.
Large ailerons, large flaps and a semi elliptical wing planform each add to the overall performance of the airframe. The wings are a standard carbon reinforced hybrid layup, resulting in low weight and high strength. The control horns are factory installed and the result of a well thought out geometry that allows for flush servo installations using 10mm or thinner servos. A maximum servo thickness of 13mm in the flap bays and 12mm in the aileron pockets, allows the use of a wide range of servos. Conventional servo linkages provide a clean, practical and most importantly, serviceable, control installation. The geometry has been optimized to use full servo travel to achieve high torque and minimal slop. Optionally, LDS control systems can be used.
The Sine Wave Spar:
Used in several military aircraft, the Sine Wave Spar has been adapted for the first time to make up the heart of a model sailplane wing. It has amazed us with its low weight, and ultra-high strength. Unlike a conventional spar, the Sine Wave Spar adds terrific torsional strength while weighing considerably less than the older non-optimized spar.
The beautifully contoured fuselage is strong, light and stiff. The Carbon/Kevlar reinforcements provide the all important resilience to the boom and also allow the electronics bay to be 2.4GHz friendly. Access to the radio gear and ballast is provided through a conventional slide-on canopy. While the long nose accentuates the pretty lines of the fuselage it also provides plenty of internal volume allowing easier balance of the model without resorting to shoehorning lead in every nook and cranny!
Control rods or rear mounted direct servos can be used for Rudder/Elevator control. These are all positioned to take the ‘head scratching’ out of installing the radio gear and to allow the use of standard 19/20mm round ballast slugs, 8 of them if you need them. The full ballast load including both the wings and the fuselage weighs in at 1.2Kg.
The rudder has been designed large enough to be effective for both aerobatics and slow landing speeds. The wing stub fairings have pre-drilled location dowel holes as well as pre routed openings for the green Multiplex connectors.
The symmetrical airfoils were specifically designed for the tailplane with an eye on increased control response using less control surface deflection. At 10%, the tail airfoil section is thicker than normal but the infinitesimal increase in drag is easily offset by the increased control response using less deflection. To further increase efficiency, pitch control is accomplished by using an elevator. No wobbly, all moving tail, the elevator is driven either by an optional ball raced bell crank from a servo in the fuse, or via a servo mounted in the fin, the latter providing the greatest precision. The tails remain removable for convenient transport or storage.
The Schwing 108 has an impressive joiner, massive is the only way to describe this part. It measures just over 35 x 12mm and was designed to be available as an optional solid UD carbon part for light DS. It is as big if not bigger than the joiners used in most 3m competition airframes!
The Schwing Corsa has been designed with a far greater capability potential than the average sports model. The pre-production models underwent thorough testing, not only to gauge flying performance, but also to refine gear installation to the point that it is straightforward and practical. The culmination of this work is an airframe that is a snap to fit out and a joy to fly.
