10. Carefully spread the wings all the way, lowering the nose of the wing on the ground. It
spreads itself (Fig. 16, 17 and 18).
Remove the wingtip protection bags.

11. From the direction of the keel install the
transverse battens in to the corresponding
batten pockets (Fig. 19).
12. Remove battens from the batten bag and
check each batten for symmetry against the
corresponding batten from the other wing.
Align the battens at their front tips, and at
about the 60% of the chord point. There
should be no deviation of more than 3 mm
(1/8’’) from one batten to the other along the
full length of the battens.
If you choose not to check your battens for
symmetry before each flight, you should, at a
minimum, check them once a month.
Aeros convention is that the red marked battens go in the left wing and green marked battens in
the right wing. Battens are numbered from the center outwards, and the longest batten in a Still
TL is designated as the "No. 1" batten. Install the cambered battens in the sail.
CAUTION: INSERT BATTENS CAREFULLY, SO AS TO MINIMISE STRESS AND WEAR ON
THE SAIL.
Never insert or remove battens with the crosstube tensioned (except for up to the last three on
each side) and never insert or remove battens with heavy wind pressure on the top of the sail or
in any condition which causes the battens to slide with great resistance in the pockets.
