RC-Easy FreeAir WWI Series Manual

Congratulations!
You have become a happy owner of the semi-scale SE 5 fighter of the FreeAir WWI series.
These models have been designed for a common recreational flying as well as for the competition use in the ACES
Combat WWI category. We strived to achieve the optimum possible compromise between the scale fidelity of the
model to the prototype, its good flying qualities and ease of construction. Thanks to the materials used the models
could be repaired quickly following eventual crashes.
Recommended equipment for the model: Servos of 5-9g weight of about 1kgcm/35ozf pull (Waypoint 060), AC
motor of 100-200W (HCS 150W), AC controller of 12-25A, three-cell LiPol battery of about 1200mAh capacity, 9-11in
propeller (GWS).

To build the model you need: CA glue, CA glue accelerator, balsa knife or similar sharp cutter, a ruler/straightedge
(preferably steel), abrasive (sanding) mesh for plasterboard hand finishing.
Building process: Glue all joints with thin CA glue. In the first phase tack-glue the joints so that the parts just hold
together, then check their relative positions and symmetry as needed and finally glue them thoroughly. Ensure that
the glue would not seep through the EPP and glue your fingers to the structure.
Wings: Glue together the wing halves as per Fig.1. At about a third of the wing chord, measured from the leading
edge, cut into the upper surface of the wing a spanwise slit . Avoid cutting too deep. Push the carbon rod into the slit .
In wings with dihedral you must warm the Al wire in the place of curve before you push in the wing, curve it and
secure with CA glue. Underlay the wing and glue the Al wire. Dihedral of wings is 30mm at the end of every half.
Curve begins 50mm from the centre of wing Fig.2
Fuselage: Glue the bulkheads into the spine, as per Fig. 3 . On the fuselage glue front shaping cut-out Fig.4 . Bend the
fuselage to the required shape and fix with adhesive tape (sticky side away from the surface) and leave for a minimum
of 30 minutes to give it the required shape - Fig. 5. Glue together the spine as per – start from the bulkhead at the
lower wing trailing edge. Tack-glue the spine with the CA glue first, then ensure there is no distortion - check the
respective planes of symmetry and the proper geometry. Then glue the parts thoroughly, as per Fig. 6 Glue the
control rod support bulkhead into the rear fuselage Fig 7 Dry fit and then glue together the engine cowling. The motor
offset is built into the parts (thrust down and right). The thrust axis offset as provided for in the kit is the base one.
Using different propellers may change it somewhat; in that case place washers and shims (not supplied in the kit)
under the motor attachment points. At this point, do not glue the cowling in place - Fig. 8,9.
Empennage: Thicken elevatror same as the wing with two Al wires Fig.10,11,12. Cut and glue in place the elevator
halves' joiner (Al wire of 1,6 mm diameter) Fig.13. Glue the horizontal tail to the fuselage. Fig. 14 Glue the vertical tail
Fig.15
Fitting servos to the fuselage: Cut openings for elevator and rudder servos into the fuselage spine below the wing
Fig. 16. The servo cables should reach to cockpit to facilitate connecting to the receiver. Insert the servos into the
openings, connect to the receiver and check their neutral position. Drill the end holes in the servo arms to
accommodate the 1,6mm thick wire and insert there the "Z" bent ends of the control rods. Slide three guide bushings
cut of the control rod guide tube on the control rods (wires) – the two shorter ones towards the servo, the longer
towards the end. Ensure the control rods run in the straightest possible line from the servo to the control surface horn
and cut grooves for control rods into the bulkheads and fuselage side walls as per Figs. 17,18,19,20. Cut a slit into the
control surface for each of the glassfibre control horns. (Note – they shall be glued in place only after connecting to
the control rod.). Install first the elevator control rod. Insert (do not tighten its screw) the servo arm in place. The
