Speed System
For better penetration in headwinds and improved glide performance in sinking air, crosswinds or
headwinds, you should fly faster than trim speed by using the accelerator system. Using up to half bar
does not degrade the glide angle or stability significantly and will improve your flying performance. To
accelerate, first make sure that you have no brake applied (remove any wraps from the brakes) and take
hold of the B risers, we recommend to use the wooden handles. Apply the speed bar smoothly and
progressively to avoid sudden changes of pitch/angle of attack (AofA) and to allow the wing to accelerate
efficiently. Maintain pressure on the B risers and use active control with a combination of the speed system
and the B risers through turbulent air. Only release pressure from the B risers when the air is smooth.
The blue tag on the riser speed system line indicates 10cm of travel, this is the speed at which the wing
has been certified. At full speed the Enzo 3 is fast but has less inherent stability; only use maximum speed
in very calm air conditions and always fly actively with the B risers/speed bar.
Active Flying
To reduce the frequency of collapses in turbulent conditions, it is essential to use active flying. The aim of
active flying is to control the pitch and internal pressure of the wing. This can be done with the brakes or
the B risers (see below), but in very turbulent air, we recommend to always use the brakes.
In turbulent air, fly with the brakes applied (approx. 20cm), this will give you the necessary feedback which
is vital to keep the wing open. It is also important to look at your wing as this gives a direct indication of
its internal pressure and likelihood of collapse. Inputs can be symmetric or asymmetric; you may have to
apply both brakes or just one to maintain equal pressure across the span/chord of the wing. Avoid flying
with continuous amounts of deep brake in rough air as you could inadvertently stall the wing. Always
consider your airspeed.
Active B Riser Control
When gliding at trim speed or in accelerated flight, we recommend to pilot the wing with the B risers. This
gives an improved feel and control over the wing enabling you to fly actively without using the brakes
(which causes drag and pitch movements). The direct feel allows you to stop collapses before they
happen and maintain higher speeds and higher levels of efficiency.
To fly with the B risers, keep hold of your brake handles (remove any wraps) and either rest your hands
on or take hold of the wooden handles located on the B risers. Now you have direct control of the AofA;
by pulling the B risers down or rearwards you increase the AofA, releasing pressure reduces AofA and
returns the wing to trim speed. With B riser control you can fly actively through turbulence, collapses can
be stopped or at least reduced with correct inputs due to the sudden increase in AofA. If you feel the nose
of the wing lose internal pressure, or you see a crease appear between the A and B line attachment points
on the sail you can quickly input the B risers to stop the collapse occurring. The amount of pressure and
size of the input is dependent on the amount of turbulence, or loss of pressure, but always avoid long deep
inputs to avoid inducing large pitch movements or inadvertent stalls.
During accelerated flight, the added control of active B riser flying further increases the efficiency and
stability of the wing. Whilst accelerated the act of pulling the B risers is exactly the same as releasing the
speed bar. This translates to direct control of speed, AofA, and internal pressure in your hands. Coupled
with active speed bar control, adjustments can be made with the B risers to optimise your speed and
internal pressure through turbulence helping you to maintain a higher average speed whilst reducing the
likelihood of unexpected collapses. When pushing the bar, if the air becomes slightly turbulent apply some
pressure to the B risers, when the air becomes less turbulent again you can reduce (or release) pressure
on the B risers for extra speed. Flying fast and efficiently in normal air requires constant attention to the
wing, it is necessary to combine B riser inputs and speed bar adjustments to keep the wing open and
pressured.
This control method is suitable for gliding in good ‘normal’ air without huge levels of turbulence, it does not
replace proper active flying with the brakes in strong turbulent conditions. If you are unsure about the air
return the glider to trim speed, release the B risers and fly the glider actively with the brakes.
Big Ears
To pull big ears, keep hold of your brake handles and take the outermost A-line (AR3) on each side, then
pull out and down (preferably one at a time) until the wingtips fold under. The size of the big ears can
be adjusted by pulling more line, or reaching higher up the line. Once the big ears are engaged you can
further increase the sink rate by using the accelerator system. For directional control while using the Big
Ears, use weight shift.
IMPORTANT
No pilot and no
glider are immune to
collapses, however
active flying reduces
the tendency to
collapse. When
the conditions are
turbulent, be more
active and anticipate
the movements of
the wing. Always be
aware of your altitude
and do not over-react.
IMPORTANT
Always keep hold of
your brakes. Do not fly
in turbulent conditions
DO NOT perform spiral
dives with the Big Ears
engaged.
IMPORTANT
Whilst accelerated DO
NOT use your brakes
to fly actively in
turbulent air, doing so
will actually make the
wing more prone to
collapse.
IMPORTANT
Regulate your speed
depending on the local
airmass. If it becomes
turbulent, release the
speed system and
fly actively with your
brakes or B risers.
