B-Stall
The B-stall is used for fast descents in emergency situations only. B-stall is performed
by symmetrically pulling down on the B-risers. This takes quite a lot of effort. The
best way to do this is to place your fingers between the lines above the maillons at the
top of the risers. You should not release the brake handles while B-stalling. As you
first pull the B-lines down the airflow over the wing is broken and the glider loses
forward speed but remains open. By pulling the B-risers further the sink rate can be
increased as the chord is effectively reduced. However, if you pull too far, (A’s & C’s
effected), then you may rosette the glider. If this happens, release the B-risers
immediately.
To exit the B-stall the B-risers should be returned to their normal flight position
symmetrically and swiftly in one smooth motion. The glider should then resume
normal flight without further input. Always be sure of this before using the brakes
again.
It is possible for the wing to resume its normal shape on release of the B-lines, but to
remain in steep descent without full forward motion. This is called a “deep stall”. It is
unlikely to happen with the HORNET, but your should be aware of the possibility. If
you suspect this has happened, simply push the A-risers forward until normal flight
returns. Only then should you use the brakes again.
Big Ears
Folding in the tips of the wing increases the sink rate of your glider. This is useful for
staying out of a cloud or descending in strong winds. You pull “big ears” by drawing
in the outermost A-lines until the tips of the wing fold under and drag behind. Firebird
gliders are fitted with split A-risers to make this procedure easy.
To increase the sink rate further, the accelerator bar may be employed, but pull the tips
in first. Remember that when the tips are in, you have reduced the area of the wing
supporting you, so your stall speed will have increased. Be sure to keep speed on and
not to use the brakes other than cautiously for re-inflation. For directional control
while using “big ears”, you should rely solely on weight shift.
To reopen the wing tips, release the small A-risers and apply a short brake input which
is best done one tip at a time to minimise the chance of inducing a stall. You will find
there is surprisingly little tendency for the glider to deviate during the process.
Caution: We advise not to use “big ears” close to the ground.
