04 Setting up the Hybrid
Sport and test-flying
Before the first flight
WARNING
A specialist must test-fly and inspect
the mini wing before your first flight.
The test-flight must be recorded on the
mini wing information label.
During production, the Hybrid Sport goes
through several quality control checks
before finally undergoing an exact type
certification test. Conformity with the
reference specimen is checked and certified
before it is delivered to the customer.
Extreme care is taken in the manufacture of
all patterns, lines and riser lengths. They
show a high level of precision and should
not be altered under any circumstances.
WARNING
Any changes or improper repairs to this
mini wing shall render invalid the
certification and warranty.
Adjusting the main brake lines
The Hybrid Sport is delivered ex factory with
a brake adjustment marked which complies
with the test sample and which should not
be altered. This adjustment is ideal. The
brake lines are as short as possible so that
the Hybrid Sport is able to react as quickly
as possible. There could be dangerous
implications if they are made shorter. There
is no reason for you to alter the brake line
length.
The main brake lines must be checked by
an expert before the test flight, and must be
fastened so that the mark is visible approx.
5mm above the knot.
Factory setting
Correctly installed brake lines have about
10cm of feed. This is how far you must pull
down the brakes before the trailing edge of
the mini wing starts to move downwards and
begins to brake. Note that the brake
cascades already cause drag by their
aerodynamic resistance.
Modern gliders such as the Hybrid Sport
have less tolerance with regard to
adjustment of the brake lines. It is therefore
normally not necessary to alter the length.
If you do nevertheless adjust the brakes,
under no circumstances should you go
above or below the tolerance levels given in
the Maintenance and Service book for the
Hybrid Sport.
Incorrect adjustment
If the brake lines are too long, the mini wing
reacts slowly and is difficult to land. The
brake lines can be adjusted during flight by
wrapping them around your hands which will
improve the flight characteristics. Adjust the
brake lines to the correct length after you
have landed. Changes to the braking
distance should always be made in small
increments of no more than 2 to 3cm and
must be tested on a training slope. The left
and right brakes must be adjusted
symmetrically.
If the brakes are shortened, care must be
taken that the mini wing is not slowed down
in trim and accelerated flight (trimmers
opened and speed bar in use) because of
the brake lines being too short. Safety
issues may arise and performance and
