Basic wing structure
Figs. 1 and 2
- Prepare the bottom centre section sheeting F1a and F1b
and glue the parts together.
Fig. 3
- Bevel the leading and trailing edge areas of the centre
section sheeting to conform to the airfoil section.
- Pin the sheeting panel down over the plan, and tack the
bottom main spar F to it.
- Slide the wing ribs F 3 and F 4 onto the main spar, check
alignment carefully, and glue them in place.
Fig. 4
- Glue the wing ribs F 5 - F 8 to the main spar, as shown on
the plan. Check that the ribs are at right-angles to the
spar.
- Remove the lug from the rib F 4.
Fig. 5
- Glue the top main spar F 9 to the structure as shown.
Fig. 6
- Glue the tip rib F 10 to the end of the wing panel as
shown.
- Glue the riblets F 11 - F 13 to the structure.
- Glue the trailing edge sheeting F 14 to the wing panel.
- Glue the leading edge F 18 to the structure, taking care to
align the ribs and riblets accurately.
Fig. 7
- Glue the aileron recess trailing edge strip F 15 and the
doublers F 16 and F 17 in place as shown.
Fig. 8
- Allow all the joints to harden thoroughly, then remove the
wing panel from the building board.
- Pin down the aileron sheeting F 19 and glue the aileron
ribs F 0 - F to it.
Assembly and operating instructions
Charterle
Fig. 9
- Glue the leading edge strip F 3 to the aileron and sand it
to the cross-section shown on the plan.
Figs. 10 and 11
- Glue the balsa wingtip F 4 to the tip rib and sand it to the
rounded shape shown.
Fig. 12
- Glue the aileron servo mount components F 5 together
in pairs, keeping their edges flush.
- The next step is to fit the servo mount covers F 6, taking
care to produce one right and one left servo mount: the
cover must be on top of the assembly; the photo shows
the right-hand mount.
Fig. 13
- This picture shows the right-hand servo mount F 5 with
the cover F 6 attached.
Fig. 14
- Trial-fit the servo mount in the position shown on the plan,
and glue it in the wing.
- The wing panel can now be sanded smooth overall using
fine abrasive paper.
- The aileron horns F 7 should not be installed until the
wings and ailerons have been covered.
Fig. 15
- Glue together the two dihedral braces F 8 with their
edges flush. Allow the glue to set hard before cleaning up
the brace assembly all round.
Fig. 16
- Mark the centre point "M" on the dihedral brace F 8, and
glue it in one wing panel as shown, using clothes pegs to
ensure a sound joint.
Note: this is a good time to build the second wing panel.
Figs. 17 and 18
- Set the aileron servos RC 1 to centre from the transmitter,
and fit the single-armed output levers RC on the output
shafts. Temporarily place the servos in the mounts, and
5
check once more that they are at neutral.
- Secure each servo with a drop of epoxy at both mounting
lugs.
Figs. 19 and 20
- Thread the extension leads RC 3 through the wing panels
and connect them to the leads attached to the servos. We
recommend that you wrap adhesive tape round the
connectors to prevent them working loose, as the
connections are not accessible once the wings have been
covered.
Figs. 21 and 22
- Slip the centre rib F 9 onto the dihedral brace F 8.
- Provisionally insert the dowel F 30 in order to align the
centre rib.
- Check that parts F 9 and F 30 fit correctly, then glue
them to one wing panel using plenty of glue to obtain a
strong joint.
Joining the wing panels
Use white glue for this stage.
Fig. 23
- Before reaching for the glue bottle, assemble the wing
panels "dry" and check that they fit together snugly: there
should be no gaps at the centre joint, and the panels must
line up correctly, i.e. not twisted or out of line with each
other.
Fig. 24
- Apply plenty of glue to all the joint surfaces.
- Push the wing panels together, align them carefully, and
clamp the root ribs securely using clothes pegs, as shown
in the photo. Leave the glued joints to set hard.
