pad is not utilized when taking it down and transporting, there
will be wear on components with cosmetic and/or structural
damage to the wing. The POH may specify where pads go
during the setup and takedown. However, when setting up
any wing it is a good idea to take pictures, draw sketches, or
take notes regarding protective pad location so they can be
put back in the proper location during take down.
Assemble the triangular control frame without attaching the
wires to the nose. [Figure 5-13] Rotate the wing up onto its

control frame. [Figure 5-14] Place the front wires near the
control bar so no one walks on them, remove, and roll up
the cover bag. [Figure 5-15] Release the wing tie straps that
are holding the leading edges together. [Figure 5-16] Spread
the wing slightly. Remove the pads from the wing keel and
kingpost. Note the protective pads still on the wing tips
protecting them from the ground during most of the wing
set up procedure. [Figure 5-17] Continually manage the
wing pads and wing tie straps by rolling the pads into the
cover bag so they do not blow away. [Figure 5-18] If the
kingpost is loose, insert it onto the keel to stand upright. If
the kingpost is attached, swing it upright. Topless wings
have no kingpost. Spread the wings as necessary to keep
the kingpost straight up, [Figure 5-19] spreading them out
carefully and evenly. Do not force anything. Ensure the wires
are not wrapped around anything. Separate the right and left
battens. Separate the straight battens (for a double surface
wing) and set them to the side. Lay out the battens, longest
to shortest from the root to the tip next to the pocket they

go into on both sides. Note the protective pads are still on
the wing tips so they are protected. [Figure 5-20] Insert the
battens into the batten pockets, starting at the root and work
out to the tip. [Figure 5-21] Most batten attachments are
double pull. [Figure 5-22] Some manufacturers use cord or
elastic, and others use a system that slips into the sail itself.
See the POH for wing details. Insert battens from the root
towards the tip about ¾ the way out on each side. Leave
the tip battens for later. Spread the wings as far as possible.
[Figure 5-23] Check to ensure all the wires are straight, not
wrapped around, and clear to tension the wing. Tension the
wing by pulling back on the crossbar tensioning cable and
pulling the crossbar back into position. This may require
signifi cant effort for some wings. Secure the tensioning
cable to the back of the keel. [Figure 5-24] If the keel does
not extend out, then support the aft end of the keel to lift the
tips off of the ground. [Figure 5-25] Move to the front and
secure the front control frame fl ying wires to the underside
nose attachment. [Figure 5-26] Remove the tip bag protectors
and install the tip battens, continuing to move from the root to
the tips on each side. Insert the washout strut into the leading
edge. Each manufacturer has its own washout strut systems
and tip battens. Some manufacturers have no washout struts.
Refer to the POH for wing specifi cs. [Figure 5-27]

Insert bottom battens for a double surface. If inside a hangar
where there is no wind, this can be done by putting the nose
down, making it easier to install the lower battens. [Figure 5-28]
If not already accomplished, lift up on the back of the keel
and put the wing on its nose. Lower the undercarriage mast
and line up the undercarriage behind the wing exactly in the
