The Espada RL is an amazing example of the worlds leading F3J technology. Designed and built by master craftsman Jaro Muller, the Espada RL has one of the best weight to strength ratios of any F3J model produced. Jaro is the industry leader in composite manufacturing, and has incorporated the newest state of the art technology into the Espada series.
• The flaps and ailerons are molded outside of the wing mold, achieving a very stiff and light surface.
• A dual spar system is used to increase stiffness and torsional rigidity on the wing while maintaining a light wing.
•The fuselage uses the most advanced technology, the boom's skin is made from a Kevlar honeycomb material, and has as a full length spar.
This technology combined together created a 70 ounces 3.7 meter model that can handle almost anything you can throw at it.
With every model Jaro produces, careful steps are taken to make the model easier and faster to build for the consumer. The RL is the fastest and easiest model to assemble on the market today. The fuselage arrives with all of the push-rods and clevises hooked up and ready to attach to the servo. The servos are mounted in the included servo box (picture on the left) that is easily removable by two hex bolts. Simply screw in the servos, attach them to the clevises, and the fuselage servo installation is finished. The control horns on the wing are made of machined aluminum, and the control horn inserts are molded into the surface. Installing the control horns is as simple as inserting them in the holes with 5 minute epoxy. The molded control horn inserts gives you an accurate height, length, and angle on every surface.
The biggest advantage of the Espada RL is its strength to weight ratio. The model is strong enough to take the hardest tow, yet light enough to hang in the lightest lift. In competition, only one model is needed for every condition, unlike other models that require a light, medium, and heavy strength. With the Espada RL don't need to make a choice between different strengths, and you wont have to adjust your flying style for different characteristics. Another advantage of the Espada RL is its thin airfoil, this lets you launch fast and lets it move easily through in the sky.
The Espada RL lands like a dream. The model is extremely stable, and with its large flaps slows down to a walking pace. The long, thin nose allows the model to stick with the slightest push.
The Espada RL is an extremely light and strong model. Easy and accurate to build, this model does it all; launches fast, moves around, and hangs with the lightest of planes. The model is a winner, just look at some of it's achievements:
