LYNX 2 OWNER’S MANUAL
Solo paraglider | EN / LTF C
Welcome to Bruce Goldsmith Design
BGD is a world leader in the design and production of paragliders. For many years Bruce Goldsmith and his
team have been developing products with world-beating performance for pilots who want the best. We apply
our knowledge to design top quality products that combine the highest performance with the safe handling our
customers value and respect. BGD pilots appreciate our quality and reliability. BGD´s world-class status is based on
the skills and expertise we have developed in combining aerodynamic design with cloth and materials technology. All
BGD products are developed and made with the same skill and attention to good design that are synonymous with
the ultimate performance and precision required by paragliders.
Congratulations on your purchase of the BGD LYNX 2
The LYNX 2 is a lightweight cross-country paraglider. It is a 2.5-liner design which means there are three line levels in
the centre of the wing and only two at the tips. It does not have full chord-wise plastic rods, which means it can be
packed down small and is easy to carry for hike-and-y or vol-bivouac. It is a cross-country wing for pilots who y
regularly and is not suitable for beginners.
As with all aircraft, regular maintenance and checks are mandatory. The LYNX 2 is made from high quality lightweight
materials and should be looked after accordingly – do not drag it over the ground. Proper care will ensure it keeps its
original safety and performance and lasts for many years.
This manual contains information on how to look after your paraglider, as well as techniques to get the best out of it
in the air. If you ever need replacement parts or further information, please do not hesitate to contact your nearest
BGD dealer or contact BGD directly.

Quick Summary
The LYNX 2 is a 2.5-liner design. The following things should be noted in particular:
1. Launch should be done using the main A riser ony (risers marked with red), without the separate AR3 (big
ears) line.
2. The risers and lines are attached with soft links which are protected by Lycra covers. It is important to lift the
covers and inspect the soft links regularly, to check they are correctly closed and are not becoming worn.
3. Rapid descent techniques: You should not B-Line stall the LYNX 2; Big Ears can be done using the AR3 line.
Note that Big Ears are harder to pull in than on a traditional three-liner. Big ears on the LYNX 2 should always
be done with some speed bar applied, to avoid the risk of deep stall.
4. The LYNX 2 was certied using collapse lines for the accelerated EN tests, because it is hard to pull the
accelerated collapses using only the A risers. If you do SIV on the LYNX 2 we recommend to only do trim
speed manoeuvres to avoid the need for using collapse lines.

Introduction
Limitations
The LYNX 2 is a solo paraglider. It is not intended for tandem use or for aerobatic manoeuvres.
It is suitable for winching. Both pilot and winch operator should have the necessary training and qualications for
winching, and the winch system should be certied for paraglider use.
This paraglider should 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 200kg
Test ight and Warranty
All information about the BGD warranty can be found on the Warranty page of our website. To benet from the
warranty, you must complete the warranty registration form on the website (www.ybgd.com)
It is your dealer´s responsibility to test y the paraglider before you receive it in order to verify the trim settings. The
waranty may be void if the test ight has not been completed by the dealer.

LYNX 2 manual EN v1.1 March 2023
Weight Range
Each wing 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 and all other equipment carried with you in ight. We generally recommend
your paraglider is own in the middle of the weight range.
If you mainly y in weak conditions you might wish to y towards the lower end of the weight range to benet from
a better sink rate. In the lower half of the weight range the turning agility will be lower and the glider will be more
damped. In strong turbulence the wing will have a greater tendency to deform or collapse with a lower wing loading.
If you prefer dynamic ight characteristics, want better speed or y in strong conditions you might choose to y
higher in the weight range. If you y in the upper half of the weight range agility and speed will be higher and you will
have greater stability in turbulence, but there will be reduced self-damping in turns and after collapses.
Modications
Any modications to your glider, e.g. changing the line lengths or 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
modications.
Brake line lengths
The length of the brake lines is set at the factory so that the trailing edge is not deformed at all when brakes are not
applied. There should be around 7cm slack in the brake lines, before they take effect on the canopy. It should not be
necessary to shorten the brake lines. However, it is possible that shrinkage can occur. If necessary, the brake lines can
be lengthened by adjusting the knots.

Harness
The paraglider was tested with a ‘GH’ (without diagonal bracing) type harness. The GH category includes weight-shift
harnesses as well as ABS style (semi-stable) harnesses.
The harness complies with the EN standard harness dimensions, which are:
• Seat board width: 42cm.
The horizontal distance between the attachment points of the paraglider risers (measured from the centre-line of the
karabiners) must be:
• 38cm for pilots under 50kg
• 42cm for pilots from 50-80kg
• 46cm for pilots above 80kg

Preparation
Connecting the speed bar
The LYNX 2 comes with accelerator risers and can be own with or without a speed bar attached. The speed bar should
be connected and adjusted following the instructions in your harness manual to ensure correct routing of the lines.
The weight-optimised speed system has universal attachments instead of Brummel hooks. These comprise a loop
with a knot, sewn into the end of the accelerator line. The line can be attached to the speed bar using a classic
larks head knot. If your speed bar has Brummel hooks you can attach to the accelerator line using this knot without
removing the Brummel hooks.
Larks Head Knot
When attaching the speed bar lines, make sure the lines run freely and are not caught around anything including
reserve handle, risers or lines.
To adjust the speed bar to the correct length, sit in your harness and ask an assistant to hold the risers up in their
in-ight position. The speed bar length can be adjusted by moving the knots, so that the bar sits just beneath your
harness seat. You should be able to hook your heels into the bar, and to attain full bar extension (the two pulleys
touching) when you push your legs out. Once you have set the bar up in this way on the ground, a test ight in calm

air can be useful to ne-tune the length, ensuring it is even on both sides.
On launch
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. Take your paraglider to the top of the take-off area, and allow the canopy to unroll itself down the hill if
on a slope. This should leave the paraglider with the bottom surface facing upwards, the openings at the
downwind/uphill end of the take-off area, and the harness at the trailing edge at the upwind side.
3. Unroll the canopy to each side so that the leading edge openings form a semicircular shape, with the trailing
edge drawn together to form an arc. The harness should be drawn away from the canopy until the suspension
lines are just tight.
Pre-ight inspection
Your paraglider is designed to be simple 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 the paraglider check the outside of the canopy for any tears where it could have been caught
on a sharp object or even have been damaged whilst in its bag. Visually inspect the risers for any signs of
damage.
2. Check the lines for signs of damage, twists or knots. 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.
