Corsa Electric 2.75m

We are looking for an experienced modeller to write a build log for this model.

The Corsa Electric is the electric version of the Corsa 2.75m slope soarer from the well regarded slope soaring designer James Hammond.

The all molded carbon and glass Corsa Electric has a superb speed range, very precise and predictable aerobatic handling, making it probably the best 2.75m aerobatoc soarer currently available. It is built strong enough for high energy aerobatics while also being light enough to be enjoyable when flown slowly.

The wing is based on the earlier Schwing Corsa designs and benefit from the revolutionary Sine Wave Spar that is now a feature of all Aeroic planes. The optimized and now stretched wing planform has undergone a series of changes throughout the development and testing of the model resulting good performance over a wide speed range.

The reducing thickness, optimally cambered sections will let you go from really slow landing speeds with the flaps down to heart thudding passes with a little reflex, yet despite its ability to carry heavy ballast loads, the airframe will thermal with the best of them. Large ailerons, large flaps and the stretched wing planform each add to the overall performance of the airframe.

Horns are factory fitted with well thought out geometry to allow flush servo installation using 10mm servos for flaps and 8mm servos for the ailerons. Using conventional linkages, you can get a clean, practical and most importantly serviceable wing installation optimized to use full servo travel to give high torque and low slop.

As used in several military aircraft the Sine Wave Spar (SWS) has been adapted for the first time to make up the heart of a model sailplane wing, and has frankly amazed us with its low weight, and ultra high strength. Unlike a conventional “Box” spar the Sine Wave Spar adds terrific torsional stiffness and yet actually weighs considerably less than the older conventional spar types. Now used in all Aeroic airframes, the Sine Wave Spar is lighter and far stronger than “conventional” spars and raises the overall performance level another few notches.

The slim and curvaceous fuselage is strong, light, and stiff with Carbon/Kevlar reinforcement and gives far more strength to the boom than most models. Electronics area is 2.4 GHz friendly with access to the radio and ballast through a slip-on nose cone. The long nose area accentuates the rakish lines but also provides plenty of space to easily balance the model. Snakes (not supplied) and/or rear mounted direct servos can be used for Rudder/Elevator control. Wing stub fairings with location dowel holes finish the fuselage with recesses for “green” Multiplex type connectors to connect the electronics pre-routed.

The partial accessory bags include a wiring loom, good quality metal wing clevises and colour coded hatch covers. The accessories assume the rudder and elevator servo are mounted in the fin, allowing short slop-free linkages. The spinner diameter is 42mm.
