Trimmer buckle and strap replacement (Nucleon, Plasma, Plus Moto and Atak)
Sometimes after long use the trimmers cease to operate correctly, i.e. they slide away of their intended position. This occurs only with the 20mm wide risers (used in Plasma, Nucleon, Plus Moto, Atak). In some cases it is just a matter of accumulated grease on the tapes, so first you can try to clean them with kleenex for example.
Currently all these canopies are produced with some "steps" sewn on the trimmer tapes which stop the sliding buckles, thus minimising possible asymmetry.
If the trimmer tapes are worn out and tend to keep sliding away, they should be replaced. For this we prepared a dedicated replacement set, including:
two new trimmer buckles with removable cross-bar for easy exchange
two new trimmer tapes with "steps"
some glue to prevent the screwes from getting loose.
Below you can see an instructional video on replacing the buckles. To put it short: the old buckles are sawed in half (they have a fixed bar), removed and replaced with new ones.
Trimmer Tape Lock
Procedures require that certified paragliders are sold exactly conforming to certification samples, without any additional functions. That's why we are forced to block any trimming on sale.
Until September 2010 our paragliders were equipped with Trimmer Dummy, to be replaced with normal trimmers on pilot's own responsibility. Now we made life easier - our paragliders come with trimmers as standard, with addition of a plastic buckle temporarily prohibiting trimmer use. All a willing pilot has to do is to slide the buckle, thus removing the constraint so that trimmer becomes fully operational.
On leaving the factory all paragliders are equipped with a Trimmer Dummy - when it is present, given paraglider conforms to EN norm. If you would like to have additional possibility of AoA adjustment, you have to replace the dummy strap with complete trimmers.
How steering lines should be attached to steering toggles
The pictures show the way steering lines should be attached to steering toggles. Such a knot cannot go untied - on the contrary, every pull on the steering line (i.e. every steering input) strengthens it. Showed knot is used by our assemblers on each wing leaving Dudek Paragliders, and in case of any alterations (mainly steering lines length adjustment) please take care to have it fixed exactly the same way afterwards.
Speed-system line replacement
How to replace a speed-system line with a new one (thick)
Sometimes it is necessary to exchange speed-system line for a new one. You can do it yourself, as shown here: english version.pdf
How to replace speed-system line of older type (thin)
When a line of older type (thin) breaks, attaching hooks to the new one can be troublesome. Thanks to Clive Bunce there is some guidance here .
Trimmers: buckle adjustment and strap substitution
Trimmers buckles used in dedicated PPG risers sometimes require adjustment. After prolonged use a trimmer strap may need a replacement, too.
Pictures show how to disassemble and replace trimmer strap.
