FLYING THE MACJET
Note!! If trims are asymmetrically adjusted, the wing will turn. Therefore trim
setting is an important part of the checklist before every flight!
Accelerated flight (speed bar applied)
When flying with the speed system applied the angle of attack is lower and the glider
increases flight speed. In contrast to most paragliders it does not decrease wing
stability; in fact the reflex gliders seem to counter turbulence even better.
To use the speed system, simply place your feet on the stirrup and push forward in a
horizontal plane. If a loss of back pressure of the stirrup on your legs is noticed, this is a
warning that the canopy is probably about to collapse. Release the stirrup and thus the
speed system immediately. Do not use the speed system in very turbulent conditions,
close to the ground or near other airspace users. Always fly with sufficient clearance
from the terrain and always keep the brake handles in your hands!
Warning!! Do not apply brakes when fully accelerated! Braking increases lift near
the trailing edge. The main lift point moves backwards. Due to this the wing can
loose stability and can lead to frontal or side collapse on accelerated flight. When
fully accelerated (maximum speed bar and trims open) using full thrust and you
rapidly decrease the thrust (e.g. close the throttle completely) you can cause the
“pendulum effect” and then the glider can surge forward which automatically
decrease the angle of attack. This also can easily lead to collapse in turbulent air.
At maximum speed-bar and fully open trims we strongly recommend steering with wing
tip steering handles. At first learn to fly using the speed system with the trims in neutral
position. It is advisable to use the speed system with neutral or half opened trims. Turns
executed in this way will be slightly wider, but the strength needed to initiate the turn is
smaller then with brakes.
Steering - turns:
The MacJet is a very responsive paramotoring glider and reacts very directly and
instantly to any steering input. Weight shift input quickens turns and ensures minimal
height loss.
From neutral to closed trim settings the turns can be done much tighter and are more
effective using a combined technique while steering with serial brake together with
wingtip steering brake. This technique is very useful for slalom competitions. Turns can
be much improved by additional use of throttle weight shift etc. With growing experience
you will be able to master these techniques and to make fully coordinated and effective
turns.
In case it is impossible to control the MacJet with the brake lines the D-risers may be
used to steer and land the canopy. Attention! Pulling brake too fast or too hard can
result in the canopy entering a negative spin.
