The trim on a paraglider changes over time. We use a laser measuring device on a rail system with a 5KG load in order to get extremely accurate consistent measurements. The laser helps avoid measuring errors which commonly occur with a tape measure. Line trim adjustments can only be as precise as their measurement, and our laser system provides the consistency needed to ensure accurate measurements.
This accuracy allows us to tune your glider with the trim measurements of all the lines. Each total line length is measured, and sent via Bluetooth to a spreadsheet for your specific glider size and model. We then tune your glider by either making trim changes with adjustment loops on the mallions, or manufacturing a new line.
The effects of a glider being out of trim can present safety issues affecting both glider performance and handling, poor collapse recovery, and bad launching characteristics. Most of the load on a paraglider is on the A and B line sets. The lines behind the A and B line sets tend to shrink more since they take less of the wing loading. Your lines will shrink over time, often more asymmetrically from side to side and front to back than one may think. Side to side inconsistencies in your line lengths can cause the glider to fly less efficiently, and can force the pilot to compensate for the glider always trying to turn towards one direction. Front to back inconsistencies make a glider’s trim speed slower, harder to launch, and closer to spin or stall while flying. Laser Trim Tuning allows us to optimize the length of your lines, bringing your glider much closer to the manufacturer’s intended line lengths. Through our years of experience, we have discovered gliders need to be tuned after 75-100 hours of use. Laser trim tunes will also equip you with even more information to ensure you can get the most value when you decide to sell your wing.
Our Laser Trim Tuning System allows us to apply the correct adjustments to achieve the best possible trim setting. You will notice the improvement in performance, the glider will be safer, and likely more responsive and enjoyable to fly. Having a used paraglider Laser Trim Tuned increases the sale value, and allows the seller and buyer to be confident on the wings condition and value at the time of sale. Note there is an extra per hour pro-rated charge for tuning gliders with soft link mallions. Soft link mallions are more time consuming for trimming when compared to tuning gliders with standard mallions.
After we tune your glider, you will receive the initial measurements of your lines, in addition to the measurements of your newly trimmed lines so that you can see first hand how each adjustment brought your glider closer to factory settings. These measurements will also inform future buyers the state of your wing that you are selling, giving them confidence that your glider is in top notch shape.
