    To correctly set up flap an aileron deflections in relation to the TX sticks movement, we recommend the following arrangement:

    Servo rail1

    Before assembling, measure your receiver, battery and other equipment, then decide on the location of the elevator and rudder servos.

    Both pushrods are located on the starboard (right) side of the fuselage. The space on the other side will be taken by the wires from the wing servos.

    We recommend using a ball joint for the rudder servo, which allows to place the rudder and elevator pushrods above one another, as shown in the picture.

    Sand the inside of the pod in the area, where the servo tray will be installed.   Mix epoxy with your favorite filler (microballoons, chopped fibers, colloidal silica, etc.) and apply it liberally to the servo tray rails.

    equipment into instruction

    Insert the servo tray/rails assembly with installed servos into the pod. The rails should be shaped so that the bottoms of the servos (e.g., JR DS368) touch the bottom of the fuselage and no deformation of the fuselage cross-section occurs. If needed, apply extra epoxy over the rails/fuselage joint.

    Servo rail is fitted with 4 screw

    Servo_rail_1

    Remove the excess of the epoxy from the inside of the pod with a cotton swab or paper towel. The outside of the fuselage may be cleaned with alcohol or gasoline before the epoxy is cured.

    The servo tray is mounted on its rails with 4 supplied screws. The receiver and the battery should be wrapped in protective foam before installing.

    After finishing assembly of the pod, glue the tail boom to it with epoxy, ensuring that the horizontal stabilizer is parallel to the wing.  The glueing surfaces are pre-sanded for better adhesion.

    If there is excessive gap between the pod and the boom, wind some thin thread over the end of the pod.

    futaba_reciver1

    Receiver protection, Futaba 2.4 GHz example :

     

    1) Cut pieces of pushrod sleeves and glue them with CA to the receiver case—they will house antenna tips (which should be oriented at 90 degrees to each other);

    2) Insert antenna tips into the sleeves and fix the antennas in place with sticky tape.

    Supra PRO Competition technical data

    Supra PRO technical data

    Supra wing test 1

    Supra wing test

    Following numerous design studies, in the Spring of 2009, we introduced optimized wing spars for Supra PRO family, which increased wing stiffness while reducing weight.  New wing spars are baked in an autoclave in special molds from CF pre-preg. We use high strength carbon fiber IMS 65.

    Vladimir’s Model’s space age design employing Rohacel core for the flaps results in unbelievably light and incredibly strong thin wings. Combination of the right stiffness and weight eliminates aileron flatter even at extreme speeds.

    Supra Spread and Supra Hard Spread are built with bi-axial Spread Tow carbon we make in-house from high strength carbon fiber IMS 65. The weight of the finished CF composite is only 38…40 g/m², which results in lighter and stronger parts.

    Supra Spread is ideal for morning flying—it has the lowest weight and sufficient stiffness for fast starts.

    We manufacture two types of the wing spars for Supra central wing section:

    Wing spars of Supra Hard Spread, Supra Glass and Supra Carbon-glass have 13 mm wide flanges

    Wing spars of Supra Spread and Supra Glass Light Electric have 10.5 mm wide flanges

    Supra лонжероны

    1 -  the spar is enveloped  in thin Kevlar fabric for improved durability;

    2, 6 – the upper and the lower flanges are hot molded in an autoclave from carbon pre-preg IMS 65;

    3 – the webbing is made from unidirectional carbon, which increases its strength against bending; induced buckling;

    4 – carbon tubing of ±45° layup improves the torsional stiffness of the spar;

    5 – the core is made from high strength foam.

    Fuselage

    The new fuselage of Supra PRO satisfies a number of contradictory requirements:

    1) The glider does not slide after landing but stops as soon as the nose touches the ground. The shape of the pod tip satisfies F3J requirements;

    2) The fuselage has minimal aerodynamic drag, thanks to the wing raised on a pylon and streamlined pod outline with CFD optimized cross-sections;

    3) The shape of the fuselage also ensures increased stiffness and strength, required for violent landings.

    Fuselage 2

    The fuselage of Supra PRO is optimized for the ease of the radio equipment installation and maintenance. The servos are installed on a removable tray, which permits easy access to the receiver and the battery.

    The fuselage of the Electric version is described at electric page.

    Tail boom structure

    Tail boom

    The tail boom is made of two layers of Spread Tow carbon laid up at ±45 degrees. Between the two Spread Tow layers, there is a longitudinal layer of the unidirectional carbon.  This design resulted in extremely stiff and light boom—the weight of the tail boom without pushrods is only 41 gram.

    Supra is shipped with finished fuselage pod, you only need to glue the nose and the tail boom together

    Supra Pro competition tail

    Supra Competition stabilizer

    The main advantage of the new built-up stabilizer of Supra Competition is the improved landing accuracy.

    We achieved that by reducing the plane inertia:

    - The 7 gram reduction of the stabilizer weight resulted in 15 gram reduction of the nose ballast.

    - The horizontal stabilizer area is increased by 7%.

    - The vertical stabilizer is also 10 gram lighter, which allowed us to remove another 23 grams from the nose.

    - The stiffnes and sthrength of the stabilizer is increased due to the use of D-box from high strength IMS 65 carbon fabric.

    -The airfoil is extremely accurate for built-up structures, thanks to comprehensive CAD/CAM design and manufacturing procedures

     

    Supra Pro Competition horizontal stabilizer


    Our new CAD/CAM design and manufacturing processes resulted in extremely accurate built-up  horizontal stabilizer, which has as low aerodynamic drag as the molded structure.

     

    Supra_pro_fixing_pin_russian

    Vertical stabilizer

    Supra has a detachable vertical stabilizer, which can be removed to facilitate transportation. The stabilizer is fixed on the tail boom with a carbon pin. It is recommended to secure the pin with a piece of scotch tape before flying.

    The rudder of Supra Competition is of ultra light built-up defing.

    The rudder of Supra PRO is of rearlier molded design with Rohaccell core and is a bit heavier.

    The weights can be compared in technical data table.

    F3J Supra PRO

    Supra PRO Competition – the plane for winning!

    Aerodynamic design by Dr. Mark Drela uniquely combines high penetration with the ability to catch even the weakest thermals using super efficient wing mechanization.

    Accurate landings are easier to achieve, thanks to ultra light tail feather. The use of new materials and advanced design resulted in considerable weight reduction of the horizontal and vertical stabilizers, which substantially decreased the tail inertial.

    The unique flight traits of Supra Competition are complemented by the streamlined fuselage, which instantaneously stops the plane at 100 point mark.

    Our continuing efforts towards design optimization make the plane stronger and lighter with each new iteration.

    Supra PRO – a good sailplane for achieving serious results.

    Dr. Drela’s original design is complemented by a modern fuselage helping with precise landings.

    Molded horizontal stabilizer originally developed by Dr. Drela still has a strong following.

    A set of wing joiners for three different dihedral angles makes this model even more versatile, allowing for fine tuning for different flying conditions and your personal flying style.
