Trimmers and reflex profile
Trimmers in the Warp affect geometry of the airfoil. At closed
trimmers the airfoil features generates more lift with decreased reflex
character (similarly as in Snake XX). The more trimmer is released,
the more reflex there is.
Always when you are flying at high speed, be it with released
trimmers, additionally engaged speed system, or with Power Attack
sysem engaged, your steering inputs must be smooth, with no rapid
movements. When accelerated, the reflex wing canopy is often
lacking support of the rear line rows – they are loose. Rough yanking
of steering handle changes the pressure distribution and trimming of
an airfoil. The airfoil can rapidly increase pitch and aggressive tuck
will follow.
Slow trimmer settings decrease sink and steering forces, so it is
possible to efficiently use the thermals.
Study drawings of trimmers and speed-system adjustment and
setting, as well as their influence on the wing shape.
Remember:
<
Trimmer setting is another part of the pre-start check list!
<
If it will be asymmetric, the wing will be constantly turning.
Speed system
Works in the Warp exactly in the same way and in the same range as
releasing the trimmers. Both systems can be used alternatively in
various proportions as needed (observing the rules described below
as for steering requirements in different speed modes).
Caution: In calm air, Speed system can be used at any
trimmer position! The increase of wind speed and turbulence
must be assessed by the pilot who should consider the safety
limits of the conditions before making any decision.
