bulent air the wing is most stable 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.
Use of the speed system does reduce the angle of attack
and therefore there is an increased risk of a frontal (or asymmet-
ric) collapse. For this reason we do not advise use of the speed
bar near to the ground or in turbulent air.

4.5 The Climb Out

Once in the air you should continue flying into wind whilst gain-
ing height. By setting the trimmers to the standard 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 Flux 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.

4.6 Normal Flight

YES YES
Once at a safe altitude you can select your cruising speed. The
faster you trim the wing, the more fuel your motor will consume
to maintain level flight. For better penetration into headwinds
and improved glide performance in sinking air or crosswinds,

trimmers set to the standard position and applying the brakes
approximately 15%, Flux will achieve its best minimum-sink
rate.

4.7 Turning

Flux 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).
