Operation Of Trimmer System; Operation Of Speed Bar; The Climb Out; Normal Flight - SKY PARAGLIDERS ZORRO Serie Manuel

IMPORTANT: Never attempt to take off with a glider that is
not fully inflated, directly overhead or if you are not fully in con-
trol of the pitch/roll of the wing.

4.3 Operation Of Trimmer System

ZORRO is supplied with a trimmer riser set. The trimmers are
a system to modify glider profile, altering the angle of attack of
the wing to set a desired trim speed.
The 'neutral' or standard position is when the trimmers are
set to the red line. The slow setting is ideal for climbing under
power, whilst thermalling and when the air is turbulent. Brake
pressure is lighter and the handling at its best on the standard
trim setting. To increase cruise speed you can use the speed
system or release the trimmers, or both. In turbulent air the wing
is most manageable on its slowest setting, i.e. with trimmers in
the standard position and no accelerator applied.
To activate them the pilot should gently push the "trimmers"
cam lock to allow the straps to slide, lowering the angle of
attack. Release the cam lock to lock the straps at the desired
setting. To tighten the trimmers, to increase the angle of attack,
the pilot should pull the straps down vertically until the desired
setting is achieved. Trimmers must be activated and deactivat-
ed symmetrically.

4.4 Operation of Speed Bar

Use of the speed bar increases the maximum speed of the
paraglider by up to 30% of the trim speed by lowering the angle
of attack.
The speed bar is a foot operated system. Pushing the bar
with your feet will activate the system. Releasing the bar will
deactivate the system.
The Skyflex active foil allows the pilot to choose the con-
figuration of the profile from slow & easy to fast & stable with
everything in between. All combinations of controls are useable
with safe behaviour; however, ZORRO is more efficient when
the tip steering is used at accelerated speeds if changes in
direction are desired.

4.5 The Climb Out
Once in the air you should continue flying into wind whilst
gaining height. By setting the trimmers to the slow position you
will achieve the best climb rate. Do not attempt to climb too
steeply or too quickly by using the brakes. The wing already has
a high angle of attitude, coupled with a higher angle of attack
(if you use the brakes) plus the engine's full thrust acting on the
pilot, this could contribute to make the glider more prone to
stall. Furthermore, in the event of an engine failure, the resulting
backward pendulum motion of the pilot and the forward dive
of the wing can result in a momentary dive until the wing and
pilot reach pendulum stability once again, possibly resulting in
ground impact if there is insufficient altitude.
Do not initiate turns until you have sufficient height and air-
speed. Avoid low turns downwind with insufficient airspeed.
The ZORRO is well damped in roll but under certain circum-
stances it is possible for the pilot to induce oscillations. This is
caused by a combination of the engine/propeller torque and
pilot weight-shift and/or brake inputs. To stop oscillations it is
best to reduce the power slightly and ensure that you remain

static with weight-shift and brake inputs. Once settled you can
once again apply full power. Under full power the torque ef-
fect will attempt to gently turn the wing, using weight-shift or
adjusting the trimmers asymmetrically is the best method to
correct this.
NOTE: Using the trimmers asymmetrically will invalidate
certification.
4.6 Normal Flight
Tip Steering
YES
Once at a safe altitude you can select your cruising speed. The
YES
faster you trim the wing, the more fuel your motor will consume
YES
to maintain level flight. For better penetration into headwinds
and improved glide performance in sinking air or crosswinds,
you should fly faster than trim speed by using the accelerator
system, and or the trimmers.
For maximum fuel efficiency whilst flying downwind, set the
trimmers to the slow setting and do not use the speed bar. With
trimmers set to the standard position and applying the brakes
approximately 15%, ZORRO will achieve its best minimum-sink
rate.

4.7 Turning

ZORRO is designed to turn efficiently and will turn without the
need for weight-shift piloting if you choose. Your wing is not
only designed to turn rapidly (with approx. 30% brake) but also
to fly slowly in order to help identify areas of lift (for efficient
climb rates) and to maintain a flatter turn to minimize sink rate
during the turn (with 15% brake).
Whilst in fully accelerated mode, (full speed bar & full out
trimmers), the brakes should not be used to turn the wing since
the wing becomes inefficient. This combination does not dest-
abilise the Skyflex foil.
The Tip Steering control, located on the D riser, is designed
to turn the wing when the trimmers and accelerator are used
