Big ears and accelerator
Once the big ears are in you can further increase the sink rate by
pushing on the accelerator bar.
NEVER try to pull the Big Ears in with the speed bar on. This
can lead to a major asymmetric deflation. Always make the
Big Ears first and then apply the speed bar.
Big ears and spiral dive
Whilst it is possible to enter a spiral dive whilst holding in Big Ears,
the high forces applied to the lower lines could exceed the breaking
strain of the lines leading to equipment failure!
Ozone strongly recommend to NOT use this manoeuvre!
Wingovers
The limit is tightly banked S-turns, commonly known as wingovers.
These must not exceed 90 degrees of bank.
WARNING: Uncoordinated wingovers can lead to large
asymmetric collapses and cravats, therefore they should
never be executed near the ground.
B-Line Stall
B-stall is for fast descents in emergency situations only. B-stall is
performed by symmetrically pulling down on both B-risers.
If you pull too much B-line the glider may horseshoe and become
unstable.
To exit the B-stall the B-risers should be released symmetrically and
in one smooth, progressive motion. The glider will resume normal for-
ward flight without further input. Check you have forward flight again
before using the brakes.
IMPORTANT: We do not recommend the use of B line stalls
with the Mantra M4. Pulling too much B line and or turbu-
lence can cause the tips to fly forward and become unsta-
ble. Spiral dive is a safer way to loose height effectively.
your feet touch the ground. Once facing the wing pull smoothly and
symmetrically down on the brakes to stall the wing. If the glider pulls
you, run toward it.
• If the wind is very strong, and you feel you might be dragged, or
lifted again, stall the glider with the C risers. This stalls the wing in a
very quick and controllable way and will drag you less than if you use
the brakes.
• Always land heading into wind!
ADVANCED FLIGHT TECHNIQUES
Rapid Descent Techniques
Ozone would like to remind you that these manoeuvres should be
learnt under the supervision of a qualified instructor and always used
with caution. Never forget that properly analysing the conditions
before launch will help avoid the need to use these techniques.
Big Ears
Folding in the wingtips increases the wing’s sink rate. This is useful
for staying out of cloud or descending quickly. To pull big ears, keep
hold of your brake handles and take the outermost A-line on each
side, then pull down (preferably one at a time) until the tips of the
wing fold under. The Outer A line is attached to the Baby A riser,
making identification and use of the big ear system easier.
Do not use the brakes other than for re-inflation. For directional con-
trol while using the Big Ears, you should use weight shift.
To reopen your big ears, release both A lines at the same time. To
help reinflation, brake gently one side at a time until tips regain pres-
sure. Avoid deep symmetric applications of the brake as this could
induce parachutal or full stalls.
IMPORTANT: You can land with the ears (you should release
the ears before final flare). Ozone do not advise you to do
this when it’s turbulent or windy due to the risk of a possi-
ble stall and lack of precision in steering.
