body when you move forward. This may be assisted by using the A-lines.
Do not pull on them; just accompany the natural rising movement of the
wing.
Trike: the pilot can choose to perform a classic inflation, by pulling the
A-risers (as you would when foot-launching) or by utilising the A-Assist
system.
The system allows the pilot to link the A-risers through A-Assist 'pulling
risers' which are connected to the trike. With this system the pilot’s
hands are free to manipulate the brakes and the throttle and control the
take off perfectly.
PLEASE NOTE!
The A-Assist system must be installed and adjusted by the pilot.
As standard, no additional carabineer is provided to attach the riser. This
additional connector performs the same function without taking the load
of the suspension lines in normal flight.
PLEASE NOTE!
Once the launch sequence has been completed, the A-Assist must
be free of any load or tension and with enough slack to allow normal
pitching of the wing and the pendulum movement of the trike.
We recommend the whole installation procedure is supervised by a
qualified professional instructor or official dealer. Only they can address
any doubts in a safe and professional way.
2.6 ADJUSTING THE BRAKES
The length of the main brake lines and the High Speed Tip are adjusted
at the factory. However, they can be changed to suit the pilot’s flying
style or lengthened to accommodate the hang-points of the trike. In any
case, we recommend flying for a while using the default factory set line
length before making any adjustment. It will enable you to become more
familiar with the R-BUS and its unique flying characteristics. If you then
decide to change the length of the brake lines, untie the knot, slide the
line through the brake link to the desired length, and re-tie the knot so
that it is tight. Only qualified personnel should carry out this adjustment.
You must ensure that the modification does not affect the trailing edge
and slow the glider down without pilot input. Both brake lines should be
symmetrical and of the same length. We recommend using a clove hitch
or bowline knot.
When changing the brake length, it is necessary to check that they do
not engage when the trimmer is used. When we open the trimmers,
the glider rotates over the C-riser and the trailing edge elevates. It is
important to check that the brake is adjusted to take into consideration
this extra distance during acceleration. With this profile deformation there
is a risk of generating turbulence and causing a frontal or asymmetric
collapse.
