Assembling the SKY HERO III
Joining the wing panels
Remove the overlapping covering film using a sharp razor blade.
Temporarily fit the two wing panels together on the dihedral brace, and check that the
root ribs line up correctly. Mark the centreline on the dihedral brace using a pencil, so
that it is inserted to the same depth in both wing panels.
Do not glue the wing panels together until you have completed this check.
The wings should be glued together using UHU wood glue or UHU plus endfest 300.
Mix up the resin and hardener according to the instructions on the adhesive
packaging (epoxy only). Apply plenty of adhesive to the inside of the dihedral brace
slot in the left-hand wing panel. Apply glue to one half of the dihedral brace and push
it into the wing panel as far as the pencil mark. Use pins if necessary to prevent it
sliding in too far. Apply a thin coating of adhesive to the root rib of the right-hand
wing panel and the projecting end of the dihedral brace. Apply plenty of glue to the
brace socket of the right-hand wing.
Now slide the two wing panels together and ensure that the root ribs meet snugly,
without gaps. Remove the pins just before the root ribs make contact. Check that the
wings are not twisted relative to each other. Wipe off excess adhesive on a piece of
kitchen paper.
Tape the panels together, and allow the glued joint to harden fully.
It is essential that the two wing panels should be joined with positive dihedral,
i.e. when one panel is resting flat on the building board, the other tip should be
about 40 mm above the surface.
The strip of white self-adhesive plastic can be applied over the joint line once the
adhesive has set hard.
Installing the aileron servo
Press the rubber grommets (supplied with the servo) into the servo mounting lugs.
Push the brass tubular rivets into the rubber grommets from the underside, so that
the flange is at the bottom. You may find it easier to insert the tubular rivets if you fit
them on a small screwdriver first.
Lay the aileron servo plate on the wing in the correct position, and draw round it
lightly using a soft pencil.
Melt the film along the marked line using a hot soldering iron, then carefully peel the
film away from the wood.
