trim speed”, but one should only ever use this trim position in very smooth conditions,
and with plenty of height, due to the greatly reduced angle of attack of the wing. If the
pilot requires more speed in turbulent conditions, we recommend that the pilot leaves
the glider in “normal” trim position and makes use of the speed system.
We recommend setting the trim in the take off position and use the speed system.
We don't recommend the use of the speed system and the trims in rouge air.
The trim lock is covered with neoprene to prevent any damage in the arms during take
off. To release the lock place the forefinger and the thumb in the back of the lock, press
the lock release tab and rotate the hand the tab 90º up. This way the trim webbing slides
easily.
> best glide
-- un-powered flight
Best glide in nil wind, and still air, is obtained at “trim” speed that is brakes fully released
and no accelerator (speed bar) applied. It is always best to fly with a light pressure on
the brakes, keeping a “feel” on the wing in case of unexpected turbulence.
When flying into (against the) wind a better glide can be obtained by using the speed
system. The following is rough guide line as to how much to apply.
-With around 10 km/h of head wind, best glide is obtained with 25% accelerator applied.
-With around 15-25 km/h of head wind, best glide is obtained with 50% accelerator.
-With 25 km/h of head wind, best glide is obtained with 75-100% accelerator.
When flying downwind (wind from behind ) the best glide is obtained between 0% brake
and 10% of brake.
The trim travel of the glider has been limited to a point where the security/safety of the
wing is still high and yet permits a gain of 12km/h. In any case it is recommended not
to use the trimmers close to the ground, or when conditions are turbulent. If turbulent
conditions are encountered, or if you are nearing the ground we recommend that you
return the trimmers without delay to the “normal” trim position, for take-off, landing and
flying turbulence.
Always fly a glider that is the correct size for you, and remember that if your flying
weight is below the stated minimum, the speed range will diminish and inflation prob-
lems may appear. Also the handling will degrade in turbulent conditions, and it will be
easier to sustain collapses. If your flying weight is above the stipulated weight range, this
will result in a higher minimum speed and faster landing speed and the stall speed of the
glider will also be higher.
