17. Connect the trike pylon to the wing hang bracket (fig. 33). Insert the heart bolt, tighten the nut
firmly and secure with a safety ring. Attach the back up loop, making u-turn around the keel tube.
Connect the rescue system bridle.
Lift the nose of the wing to allow for the front wheel to be rolled rearward over the control frame so
that the base tube is in front of the cockpit and the rear of the keel tube rests on the pylon. Make
sure the protection pad on the main upper pylon is in proper position and protects the pylon against
bottom rear wires.
18. Remove the wingtip protection bags.
Remove battens from the batten bag and check each
batten for symmetry against the corresponding batten from the other wing. Align battens at their
front tips, and at about the 60% of the chord point. There should be no deviation of more than 3mm
(1/8’’) from one batten to the other along the full length of 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 go in
the right wing. Battens are numbered from the center outwards, and the longest battens in a Sting
Ray are designated as the "No. 1" battens. Install all cambered battens in the sail.
CAUTION:
INSERT BATTENS CAREFULLY, SO AS TO MINIMIZE STRESS AND WEAR ON
THE SAIL.
Never insert or remove battens with the cross tube 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 battens to slide with great resistance in their pockets.

19. Remove the auxiliary bungee from the
shackle and the hook.
Check that the pull back (cross tube
tensioning) wires are not twisted. Take the
shackle with one hand. At the same time with
another hand pull the crossbar backwards –
this will considerably help attaching the
shackle to the hook, placed on the keel tube.
Attach the shackle on the hook (fig. 34).
20. Connect two parts of the tip batten so that
the sharp (angled) part of them, when
connected, is pointed towards the outer part
of the wing. Push the tip batten on the hinge
with a hand until the tip batten fixates in the
kinematic lock.
Fix all the battens with the
double tensioned
ropes (fig. 35) and rubber bands (fig. 36).
