The Eternity is the latest offering from Bohuslav Majercik of Slovakia. Boho was the designer and producer of the Infinity series of F5J models.
The Eternity is an all new design. At the core of the new model is the highly efficient 3.97M solid core wing with a brand new aero package from Dirk Pflug.
CNC aluminum molds for the Eternity were produced by GCM in Poland (Vertigo makers). The molds have internal heating elements for precise and efficient post-curing,
this technology was developed by GCM. Extremely rigid molds, high temp post-cure, and high pressure in layup results in a superior surface quality that is more durable
than many other models on the market.
The all new triple dihedral wing is more efficient in a straight line and in circling. Having more, slightly smaller angle dihedral changes rather than one bigger change
of dihedral looked a worthwhile gain in the calculations especially when combined with an optimized planform and aspect ratio (22:1) all designed to work together as a package.
Although the wing is triple dihedral, only 4 servos are used. The outer aileron and inner aileron or slaved together with a rigid fiberglass plate that is installed during the manufacturing process. There is no slop in the system and both surfaces are quite rigid.
All new thinner airfoils allow the model to penetrate at lower weights. The new airfoils where developed for a wide
speed range. Extended laminar boundary layer flow across a wide range of angle of attacks meaning lower drag across a wider speed range.
The Eternity has an all new V-tail design with the boom mount being carried over from the Infinity Evo series. The V-tails are very easy to
install and remove, much easier than most models.
The four piece wing coupled with the two piece fuselage design makes the model very easy to ship and transport. Users can purchase spare nose
pods to experiment with CG and motor setups. The nose is cut to 30mm from the factory. The model will pack down into a box 120cm long x 28cm x 10cm.
As per the Infinity, the front of the nose is aerodynamically designed by Giorgi Mirov (GM props) to make sure the blades fit as close to the fuselage as possible.
The Eternity is highly pre-fabricated and comes with IDS horns and arms installed. If special ordering a model please specify servo choice.
Wiring is already installed in the center panels and fuse side harnesses are assembled and provided. The model is supplied with a very
extensive hardware package, control throw gauges, ballast, and wing and tail covers.
