3. Cercaon
The BiGolden3 has passed European cercaon EN/LTF in category B in both sizes 39 and
42. The EN cercate of each BiGolden3 is found on the rib in the middle of canopy.
NOTICE: The BiGolden3 is constructed for hill or tow launches. Use of a subsidiary motor has
not been tested for by the manufacturer or by the Para-test!
This glider is not meant for jumping from a plane, balloon or for jumps with a delayed
opening of the canopy!
4. Adjusng your glider
Every BiGolden3, before it is given to a customer, goes through a nal check-up and test-
ight to verify that its characteriscs and measurements correspond to the manufacturer’s
specicaons. You may only make adjustments to the brake line lengths and only then in
keeping with the recommendaons of this manual.
Other adjustments or changes to your BiGolden3 lead to a loss of guarantee, airworthiness
and validity of the European cercaon. Amateur modicaon may endanger yourself and
other pilots. If you do have any suggesons for improvements let us know and our test-pilots
will try out your ideas without risk to yourself.
4.1. Brake line adjustment
The BiGolden3 risers have oponal posions for the
guide pulleys for the main control lines to suit each
pilot’s physical build, harness hangpoints, or style of
ying. As standard pulleys are placed on the upper
posion – see the picture – which ts most cases.
When you receive your new BiGolden3 the brake line-
length is adjusted to be the same as that used during
the tests. This length should suit most pilots and is
indicated on the main control line.
It is of course possible to adjust the brake
line length to suit each pilot’s preference.
We recommend that you act wisely when adjusng
brake line length and change the length in small
successive steps.
If you need to adjust brakes back to the basic posion
and the marks on the main brake lines are vague,
for the BiGolden3 42 use lengths 302 cm and for the
BiGolden3 39 use 294 cm.
Brake lines that are too short:
1) may lead to fague from ying with your hands in an unnatural posion,
2) will impede recovery from certain unstable maneuvers and
3) will certainly reduce your glider’s speed range.
Brakes that are too long will:
a) hamper pilot control during launch
b) reduce control in extreme ying situaons
c) make it dicult to execute a good are when landing.
Each brake line should be ed securely to its control handle. Only use knots that will
guarantee this, such as a Dragon’s Knot.
