4.2.2.8. Attach the hook of the top rear wire with the
washout wires to the thimble of the top front wire.
Make sure that the hook is not inverted and the reflex
wires or top wires are not twisted.
4.2.2.9.Remove the battens from the batten bag, and check each batten for symmetry against the corresponding
batten from the other wing. Align the battens at the nose, and at about the 60% chord point. There should not be
any deviation of more than 3mm (1/8’’) from one batten to the other along the full length of the battens.Correct any
that are asymmetric using the template.
Aeros convention is that red marked battens go in the left wing and green marked battens in the right. But you can
feel free to install them the other way around, i.e. red marked battens go to the right and green marked battens go
to the left. This is because Aeros do not tune glider’s turn by changing battens camber, so originally your glider
comes with left and right corresponding battens symmetrical between each others. Battens are numbered from the
center outwards, and the longest batten in a Profi is designated as the "# 1" batten.
Install the cambered top surface battens in the sail, leaving out the shortest two on each side for now. Insert the
battens carefully, so as to minimize stress and wear on the sail. Never insert or remove top surface battens with the
crossbar tensioned (except for up to the last two 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.
If you choose not to check your battens for symmetry before each flight, you should, at a minimum, check them
once a month.
