Dudek Cabrio Synthesis, User Manual

After warming up the engine put the power unit on, turn to face the wing, go 
to the risers and clip them in appropriate carabiners.

Pulling on the front and rear risers open the cells. It is a good idea to pull up 
the wing briefly in order to check that the lines are not tangled. Holding 
risers, brakes and throttle as described above, pull the front risers and raise 
canopy over your head. On most occasions you will not have to brake it, 
especially if the trimmers are set for fast flight. Perhaps it does not agree 
with our experience, but this is the way the reflex profile works. When the 
trimmers are opened (set above “0”), the Synthesis Cabrio profile stabilises 
the wing and does not allow it to surge forward. It can even stay back a little 
- in such case pull the brakes a little and the glider will come forward.

Once you have it overhead, turn around, open the throttle and take off. As 
with the classic launch, in this case too you have to find such combination of 
trimmers, brakes and throttle settings that will give you the best speed and 
climb rate.

CAUTION:

You are launching with your hands crossed. You have to really master this 
technique before trying it with a running engine on your back.

When clipping in the crossed risers, you can find proper connection of the 
speed system particularly hard. Be careful not to confuse the risers!

Climbing

Once you took off safely, continue heading against the wind, using brakes to 
correct rate of climb. Do not try to climb too steeply - attempts to increase 
climb rate by pulling the brakes will have an adverse effect: due to the 
additional drag actual rate of climb will worsen, and with the throttle fully 
opened even a stall can happen.

In powered flight the Synthesis Cabrio behaves more like an aeroplane than 
a paraglider, and it is good idea to think about it in this way. If there are no 
obstacles present, it is by far safer (and more impressive for the spectators) 
to fly level for a while after take-off and gain some speed before converting it 
to height with a brief pull on the brakes.

Another reason not to try climbing too steeply is the risk connected with 
engine failure at low altitude. Although Synthesis Cabrio in a steep climb 
does not stay back so much as conventional paragliders do, low speed can 
easily lead to a stall. Besides, you should always be able to land safely in 
case of engine malfunction, so it’s better not to take unnecessary chances 
and fly with a safe margin of speed.

Depending on the power unit geometry, it is possible that after take-off you 
will notice a propeller torque (turning moment). It will try to turn you around,
