Rear-riser control
As any other speedriding glider, the Nano 4 reacts very well on rear-riser input, especially
with open trimmers. For hook turns, we recommend to use the rear-riser.
WARNING: Rear-riser control should not be used in strong turbulence. In this case, close
the trimmers and fly the glide actively with the brakes.
Active flying
Practice active flying to eliminate collapses in all but the most turbulent conditions.
Keep tension on the brakes approximately equal to the weight of your arms. This allows you
to stay relaxed and sensitively feel the internal pressure in the wing through the brakes. If you
feel a loss of pressure in one or both sides of the wing, quickly apply the appropriate brake(s)
to regain pressure. Release the brake promptly as soon as normal pressure is resumed.
If you miss the above timing and get a collapse, be sure to first raise your hands and
release the brakes before considering any other corrective actions.
The Nano 4 has excellent pitch stability. Nonetheless, in turbulence or during manoeuvres,
the glider may pitch. If the glider pitches in front of you, apply brake to slow it down. If the
glider drops behind you, ease off the brakes to allow it to speed up. The objective is to
reduce the pendulum effect by adjusting the speed of your glider so that glider and pilot are
travelling at the same speed.
The same general principles also apply when gliding with open trimmers.
Summary: "Active flying"
Ɣ The pilot sits upright in his harness, his view goes in the direction of the flight.
Ɣ
He constantly responds to increasing and decreasing brake pressures with the aim of
maintaining a constant pressure on the brake lines.
Ɣ The further in front of you the glider pitches, the larger the brake input required, but
for a shorter duration.
Ɣ When brake pressures decrease, brake firmly; when brake pressures increase, ease
off the brakes.
WARNING: Never release the brakes when the glider is behind you but accelerating
forwards.
Rapid descent techniques
Some flying situations call for a very rapid descent to avoid a dangerous situation, e.g. the up
current from a cumulus cloud, an approaching cold front or a storm front.
Rapid descent methods should all be practised in calm conditions and at sufficient altitude
so that a pilot is then able to employ them effectively if extreme conditions arise. Rapid
descent techniques are divided into three different manoeuvres which increase the sink rate
in a safe and controllable manner. For the Nano 4 we recommend only spiral dives as Big ears
and B-stall are not appropriate for speedriding gliders.
