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.

Welcome

LYNX 2 manual EN v1.1 March 2023

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 certied 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.

Quick Summary

LYNX 2 manual EN v1.1 March 2023

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 qualications for

winching, and the winch system should be certied for paraglider use.

This paraglider should not:

1. Be own outside the certied 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 benet 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.

Introduction

LYNX 2 manual EN v1.1 March 2023

Weight Range

Each wing size is certied 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 benet 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.

Modications

Any modications to your glider, e.g. changing the line lengths or the speed system, can cause a loss of airworthiness

and certication. We recommend that you contact your dealer or BGD directly before performing any kind of

modications.

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.

Introduction

LYNX 2 manual EN v1.1 March 2023

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 inating the canopy in the wind will help to sort out the lines.
