This glider is not intended to be used for aerobatic manoeuvres.
This paraglider must not:
1. Be own outside the certied weight range
2. Have its trim speed adjusted by changing the length of risers or lines
3. Be own in rain or snow*
4. Be towed with a tow-line tension in excess of 200 kg
*We strongly advise against ying in the rain. A wet canopy is much more likely to enter a parachural or full stall (see
chapter 5). If you y into a rain shower, you should immediately go and land somewhere safe, steering the canopy
gently and avoiding manoeuvres such as Big Ears which can make it more likely to stall.
It is your dealer´s responsibility to test y the paraglider before you receive it. The test ight record is in Section 8 of
this manual. Please be sure that this has been completed by your dealer.
Failure to test y a new paraglider may invalidate any warranty.
In order to enjoy full benets of the BGD warranty, you are required to complete the warranty form on the website.
Any modication, e.g. change of line lengths or changes to the speed system, can cause a loss of airworthiness and
certication. We recommend that you contact your dealer or BGD directly before performing any kind of change.

However, the length of the brake lines should be adjusted according to whether it is being own with high or low
hangpoints, or trikes.

3. Preparation
1. Select a suitable take-off area determined by wind and terrain, clear of any obstacles that may catch in the
lines or damage the canopy.
2. Open out your paraglider so that the bottom surface is facing upwards, with the openings at the downwind
end of the take-off area and the harness at the trailing edge at the upwind side.
3. Unfold the canopy to each side so that the leading edge openings form a semicircular shape, with the trailing
edge drawn together as the centre of the arc. The harness should be drawn away from the canopy until the
suspension lines are just tight.
4. Prepare and check your paramotor, according to the manufacturer’s instructions.
5. Connect the wing to the chassis, ensuring the risers are connected the right way round and that the maillons
or karabiners are correctly closed.
Take care to protect yourself and other people from the propeller, ensuring you start your motor up at a
safe distance from other people. The blades can pick up and re out debris which could injure people several
metres away. Remember there are inherent risks with petrol, oil and volatile or ammable materials.
Pre-ight inspection
Your paraglider is designed to be as simple as possible to inspect and maintain but a thorough pre-ight procedure is
mandatory on all aircraft. The following pre-ight inspection procedure should be carried out before each ight.
1. Whilst opening out the paraglider check the outside of the canopy for any tears where your paraglider may

have been caught on a sharp object or even have been damaged whilst in its bag.
2. Check that the lines are not twisted or knotted. Divide the suspension lines into groups, each group coming
from one riser. By starting from the harness and running towards the canopy remove any tangles or twists in
the lines. Partially inating the canopy in the wind will help to sort out the lines.
3. It is particularly important that the brakes are clear and free to move. Check the knot which attaches the
brake handles to the brake lines. Avoid having too many knots, as there is a risk the knots could become stuck
in the brake pulleys. Both brakes should be the same length and this can be checked by asking an assistant to
hold the upper end of the brake lines together whilst the pilot holds the brake handles. The brake lines should
be just slack with the wing inated when the brakes are not applied. After checking the brake lines lay them
on the ground.
4. Always check the riser maillons and the attachment points to the paramotor frame or buggy. It is strongly
recommended to use a safety strap. Before getting into the harness you should be wearing a good crash
helmet. Put on the harness ensuring all the buckles are secure and properly adjusted for comfort.
5. Ensure the trimmers are fully closed and maillons at the same height – the position recommended for take-off.
Your paraglider is now ready for ight.

4. Flight Characteristics
This manual is not intended as an instruction book on how to y your paraglider. You should be a qualied pilot or
under suitable supervision, but the following comments describe how to get the best from your wing.
Weight range
Each size is certied for a certain weight range. The weight refers to the ‘overall take-off weight’. This means the
weight of the pilot, the glider, the harness, the paramotor and all other equipment carried with you in ight.
We recommend your paraglider is own in the middle of the weight range.
If you y in the lower half of the weight range the turning agility will be lower and the glider will be more damped,
but it will have a slightly increased tendency to collapse in strong turbulence. If you mainly y in weak conditions you
might choose to y towards the lower end of the weight range.
If you y in the upper half of the weight range you will have greater agility and speed, and greater stability in
turbulence, but your wing will be less damped in turns and after collapses. If you prefer a dynamic ight characteristic
you should choose to y higher in the weight range.
You should never y a paramotor in strong turbulence or violent winds.
Take-off
Your paraglider is easy to inate in both light or stronger winds and will quickly rise overhead to the ying position.
The best ination technique is to hold one A-riser in each hand. The best launch characteristics are obtained with the
trimmers in the fully closed position, maillons aligned, unless the wind at launch is more than about 10km/h, in which
4. Flight Characteristics

LUNA2-manual-EN-1-4 June 2019
case we recommend that the trimmers be partially released for launch.
Never try to launch if the wing is not perfectly inated above your head and you do not have full control of pitch and roll.
Initial Climb
Once in the air you should continue to y into wind while gaining altitude. Leave the trimmers in the take-off (closed)
position to get the best climb rate. Do not attempt to increase your climb rate by braking, as using the brakes
combined with the engine’s thrust can increase the angle of attack to the point where the wing can stall. In addition,
this high angle of attack can result in a big dive if the motor suddenly dies, which could be dangerous if you are near
the ground.
Do not initiate a turn until you have enough height and speed to do so.
In certain circumstances, a pilot can induce unintended oscillations. This can be due to a combination of the engine/
propeller and pilot’s weightshift and / or action on the brakes. To stop these oscillations you should reduce the
power, ensure that you are seated centrally and not accidentally applying weightshift, and that you are not acting on
the brakes. Once the oscillations have stabilised you can gently reapply power.
Straight ight and trimmers
After take-off, once you have gained a safe altitude, if you want to increase your speed you can open up the trimmers
completely, keeping your hands up.
To reduce fuel consumption or to y in thermals, the trimmers should be closed, pulled down to their maximum.
It is important to regularly check the wear on the trimmers and that the system is functioning cleanly with no sticking
points. If they are showing signs of wear, the trimmers should be replaced. This can be done by the pilot.

Turning
The rst turns should be gradual and progressive. The rst action to change direction should be the movement of your
weight in the harness towards the side of the intended turn. Then gently relax the pressure on the outer brake, and
gently apply pressure to the inner brake until you attain the desired bank angle. To adjust your speed and turning-circle
size, coordinate your weightshift with pressure on the outer brake.
Remember that to violently apply pressure on the brakes is dangerous and should be avoided. Never initiate a turn if
you are ying slowly, as you risk the glider entering a spin.
Landing
Set the trimmers to the closed position and set up your approach downwind of the landing eld. When your height
above the eld is around 40m and you are in a good position to land in your intended landing spot, switch the engine
off* and make your nal approach, keeping your hands up to keep plenty of energy in the wing until you are about a
metre above the ground. Flare, braking slowly and gradually to slow down the wing until you are close to the stall-
point and able to land on your feet.
*If you land with the engine running there is a considerable risk of rotational propeller damage, (lines passing through
the propeller, or even injury).
Active Piloting
Active piloting means ying in empathy with your paraglider. This means not only guiding the glider through the air
but also controlling the movements of the wing, especially in thermals and turbulence. If the air is smooth the wing
does not need much input from the pilot, but in turbulent air a continual action of the pilot on the brakes and in the
harness is necessary. These reactions are instinctive in experienced pilots. It is essential to maintain contact with the
paraglider by a light pressure on the brakes. This allows the pilot to feel decreases in the wing’s internal pressure
