Adjustable Brake Position
The height of the brake handles can be adjusted according to pilot
preference to suite the power unit's hang points height. There
are 2 settings: upper and lower. The upper setting (as set by the
factory) is for low hang point motors whilst the lower setting is for
units with higher hang points.
If you lower the brake handle, you must also lengthen the brake
lines accordingly. Moving the brake handles to the lower pulley
requires adding 17cm to the overall brake line length - use the ap-
propriate mark on the brake lines.
• First undo the brake handle's knot and remove the brake line
from the upper pulley.
• Re-route the brake line through the lower pulley
• Re-attach the brake handle with an appropriate knot at the
correct length using the second mark.
IMPORTANT: If you adjust the brake handle height, you
MUST re-lengthen the brake lines accordingly. 17cm
Trimmers
The Spark is supplied with a trim riser set. The 'neutral' or stan-
dard position is when the trimmers are pulled all the way down. It
is in this position that the wing is certified. The standard (certified)
trim setting is ideal for climbing under power, whilst thermalling
and when the air is turbulent. Brake pressure is lighter and the
handling at its best on the standard (certified) trim setting.
To increase cruise speed you can use the speed system or release
the trimmers, however you should not do both at the same time.
Always return the trimmers to the slow position before us-
ing the speed bar
In turbulent air the profile is very stable. It will resist reasonable
levels of turbulence with a high resistance to collapse without pilot
input. However in strong turbulence Ozone recommends to return
the trimmers to the standard position (pulled down) and fly the
glider actively. This way, you will be in the best position to react
correctly should an incident occur.
NOTE: The standard position is when the trimmers are
pulled down to the slowest position. In this position the
maillons on the risers are level.
IMPORTANT: Do not use the speed system with the trim-
mers released - always return the trimmer to the slow posi-
tion before engaging the speed bar.
NOTE: The Spark is certified in accelerated flight with the
speed bar only and the trimmers set in the standard or
slowest position. Releasing the trimmers invalidates any
flight certification. For un-powered flight and valid certifica-
tion the trimmers must be pulled to the slow position and
locked in place using the D ring.
Accelerator System
To set up an accelerator on the ground, ask a friend to pull your
risers into their in-flight position while you sit in your harness. Now
adjust the length of the line so that the main bar sits just beneath
your seat. You should now be able to hook your heel in to the sec-
ondary (lower) loop of the accelerator.
The accelerator must be slack enough to ensure that the front ris-
ers are not pulled down in normal flight, but not so long that it is
impossible to use the full range of the speed system.
Once set up, test the full range of the speed system in calm fly-
ing conditions: ensure that both risers are pulled evenly during
operation. Fine-tuning can be completed when you are back on the
ground.
IMPORTANT: Using the accelerator decreases the angle of
attack and can make the gliders recovery from a collapse
more aggressive, therefore using the accelerator near the
ground or in turbulence should be avoided.
