6.4 TRIMMERS AND SPEED-SYSTEM SETTINGS
You are free to experiment with all possible settings,
as long as you are at safe altitude
and watch the weather . Fully opened trimmers increase the speed of the wing and with it
overall penetration and stability, but when trimmers are opened it is highly
recommended to use secondary steering only ( stabilo steering), using the main brake
handles will increase the risk of a collapse.
As forces on the brakes grow at high speeds, the weight shifting or steering with STABILO
STEERING system becomes increasingly effective.
STABILO STEERING system can be used in all trimmer and speed system settings,
also in combination with main brake handles.
At maximum speed bar and fully opened
trimmers we highly recommend steering with STABILO STEERING system.
Strength needed to initiate the turn will be smaller and there will be no decrease in speed.
On the other hand, slow trimmer settings decreases sink and steering forces, so it is
possible to efficiently use the thermals.
Worth noting is the
NRG PRO II/NRG XC II
’s
impressive speed range -the maximum
speed is almost three times greater than stall speed.
Turns can be much improved by additional use of throttle, speed-system etc. Once you
master these techniques, you will be able to execute fully coordinated and effective turns.
REMEMBER:
Trimmer setting is another part of the pre-start check list!
If it will be asymmetric, the wing will turn all the time.
6.5 LANDING
In PPG flying there are two kinds of landing: with and without power.
6.5.1 POWER OFF LANDING
At an altitude of 50 meters switch the engine off and glide as you would on a conventional
paraglider.
It reduces the chances of damaging the propeller on landing, but on the other hand there
is only one attempt possible -so it has to be done right!
NRG PRO II/NRG XC II
preserves the energy well, so there is a long float necessary,
exchanging the abundant speed for lift with your brakes.
6.5.2 POWERED LANDING
Make a flat approach with the engine idling, then level out and lose the speed before final
flare.
