|Electra2 is the ultimate high tech light weight electric sailplane designed for F5J-FAI competition.
The wings have a relatively thin aerofoil and wide chord flaps. The ailerons are extended to the end of the tip to give you more flying agility along with an outstanding soaring capability. By using 4 servos mounted directly in the wing, the flaps and ailerons allow camber changing of the wing section in all phases of flight, a wide speed range and crow braking for precision landings.
Wings have a carbon main spar; meanwhile the complete wing is made using unique bi-axial Spread Tow Carbon Fabric with direction ±45 degree. This structure allows a good increment of torsion stiffness with minimum weight and flying in wind conditions up to 12 m/s.
The 3-piece wing is completely assembled ready to install servos up to 13mm thick for the flaps and 10 mm for the ailerons. Delivered with a pair of light, hollow wing-joiners, not meant for winch launch!
The empennage is solid core with moulded carbon and glass skins and carbon spar caps. The removable, bolt-on fin/rudder moulding is works-installed onto the carbon fuse. The horizontal stab is a one-piece moulding bolted to the fuselage.
The fuselage is compatible with 2.4 GHz radio systems, being pressure-moulded using a Kevlar/Spread Carbon combination with extra carbon reinforcements. The two servos for the tail surfaces are mounted in the canopy bay. The Bowden link is very straight allowing a very precise control with a simple servo installation.
There is plenty of room for a geared motor, ESC and 3s LiPo battery in the canopy compartment with an easy access to the interior of the model. A ballast option is available (see images right of the ballast holder and ballast rod).
A variety of different size motors can be fitted into the fuselage, the standard factory installed firewall is ready for a spinner with 30 mm diameter. Bigger spinners for larger gearbox/motor combinations can be installed simply by cutting back the nose (up to 38 mm spinner dia.).
Wing bags and a cable harness with JR connectors and DB9 plug system are available as extras.
