Accelerator System; Basic Flight Techniques - Ozone Mantra M2 Betriebshandbuch

trim speed has also increased compared with the original Mantra!
The M2's intakes have been reduced slightly in order to obtain the optimum position
for performance, inflation characteristics, and re-opening behaviour.
The M2's speed system is a completely new design as a result of the 3-line concept
and is more efficient with a higher speed range with a shorter speed system travel.
The M2 is a true high performance wing, with no exceptions! We hope you enjoy flying
the M2.
Bag
The bag has been designed to be comfortable and useful (padded hip belt, ergonomic
and adjustable shoulder straps). Its large volume will allow you to store all your kit
whilst still being comfortable for hiking. We've also added some pockets on the side
and on the top, handy for all those easily lost accessories.
Brake Lines
The brake line lengths have been set carefully during testing. We feel it is better to
have slightly long brake lines and to fly with a wrap (one turn of line around the hand).
However, if you do choose to adjust them, please bear in mind the following:
• Ensure both main brake lines are of equal length.
• If a brake handle has been removed, check that its line is still routed through the
pulley when it is replaced.
• When the brake handles are released in flight, the brake lines should be slack. There
must be a substantial "bow" in them to guarantee no deformation of the trailing edge.
• There must be a minimum of 10cm of free play before the brakes begin to deform
the trailing edge. This prevents the trailing edge from being deformed when using the
speed system.
IMPORTANT:
In the unlikely event of a brake line snapping in flight, or a
handle becoming detached, the glider can be flown by gently pulling the rear
risers (C-risers) for directional control.
Risers
The Mantra M2 has been designed with 3 risers. Each riser is covered with coloured
webbing; this allows them to be easily identified.
The A's are RED. You will notice that the A's are split in two parts. The small riser on
the back, holding only one line, is the "Baby A"; it has been designed to make applying
"Big Ears" simple.
The B's are BLUE
The C's are BLACK

Accelerator System

To set up an accelerator on the ground, ask a friend to pull your risers into their in-
flight position while you sit in your harness. Now adjust the length of the line so that
the main bar sits just beneath your seat. You should now be able to hook your heel in
to the secondary (lower) loop of the accelerator.
The accelerator must be slack enough to ensure that the front risers are not pulled
down in normal flight, but not so long that it is impossible to use the full speed range
of the Mantra M2.
Extending the secondary (lower) loop of the accelerator fully will take the Mantra M2
through approximately half its accelerated speed range. Should you need even more
speed you should hook your feet on to the upper bar, which you can then extend until
the pulleys on the risers touch.
Once set up, test the full range of the accelerator in calm flying conditions: ensure that
both risers are pulled evenly during operation. Fine-tuning can be completed when you
are back on the ground.
IMPORTANT:
Using the accelerator decreases the angle of attack and can
make the glider more prone to collapse, therefore using the accelerator near
the ground or in turbulence should be avoided.
Total weight in flight
Each Mantra M2 has been certified for a defined weight range. We recommend that
you respect these weight ranges. If you are between sizes the following information
may help you make a decision as to which size to buy:
If you want better speed, precise handling, if you generally fly in mountains and/or in
strong conditions, you should chose to fly in the top part of the weight range.
If you want a better sink rate, if you generally fly in flat lands and/or in weak conditions,
you may choose to fly in the bottom part of the weight range. Remember, you can
always add ballast for when conditions are stronger.

BASIC FLIGHT TECHNIQUES

To familiarize yourself with the glider it is a good idea to perform practice inflations
and ground handling. For pilots already accustomed to performance wings you should
have no difficulties flying the Mantra M2 for the first time in suitable conditions that
you would normally fly in. For those pilots moving up a level (eg from a DHV 2) then we
recommend that first flights should be in smooth conditions on a familiar site and with
your normal harness to get accustomed to your new wing.
Preparation
Lay out the Mantra M2 on its top surface in a pronounced arc, with the centre of the
wing higher than the tips. Lay out the lines one side at a time. Hold up the risers and
starting with the brake lines, pull all lines clear. Repeat with the C, B and A lines, laying
the checked lines on top of the previous set, and making sure no lines are tangled,
knotted or snagged. Mirror the process on the other side.
