Details

The Ultima 2 is DS composites newest F5J competition model. Optimized specifically for F5J, it sports a brand new wing, fuselage and tails and features a 3 piece wing (3.65 meters or 4 meters versions), a two-piece 2.4 friendly fuselage (nose and main fuselage) and detachable tails for easier transport. The two parts of the fuselage are interlocked by the wing when mounted on the fuselage. This means to assemble the fuselage you just need to slip the nose piece on the main fuselage, plug the motor connector, install the wing via 2 screws and the nose is locked into position and ready for flight. No tape, no dedicated screws, perfect alignment. An added bonus is the ability to replace the nose and motor system with a nose that has a stronger motor system mounted for windy conditions. Interchangeability allows changing the motors between models within just a handful of seconds and assembly at the field is as easy as can be.

Production of the Ultima 2 is done in Aluminum pressure molds. Wings and tails are full Rohacell core. Fuselage is pressure molded similar to DLG fuselages. Lessons have been learned from the Ultima 1 and the molds were designed lighter and more accurate and also analyzed to reduce deformations in the production process. The mold for the center section is a piece of art milled in one part with the dihedral angle in the middle. This prevents deformation and improves the surface quality at the very root. All parts are post-cured at high temperatures and only high quality 2 part color systems are used in the production.
