Great video! I would suggest to anyone thinking of trimming their own gliders to measure the actual trim result when using double loops, larks foot etc. The thickness of the riser mailons/softlinks AND the thickness of the lines has a large effect on the resultant reduction in length, using a "double loop" on a thin mailon and a thin C line may only reduce it's length by 7mm but a "double loop" with a thick A line on a soft link could reduce it's length by 25mm - a huge difference! The same with upper cascades, the amount of line reduction further up is hugely reduced, a "double loop" may only reduce a line by 5mm...
In my movie, maybe not clear enough, the second table I show at the end with the trimmed values getting close to the reference lengths is a result of measuring the lines after putting in loops. Indeed if the initial loops don't do the job, you need to further adjust, good comment that needs attention. Thanks for reminding us Darren.
Tom, thanks for the video. Are you not concerned for the overall pitch balance of the glider? For example let's say the average of all the lines on the left A1 group are within factory tolerance, but on the long side, say +6mm. And the average of all the left B1 line group is within tolerance, but on the short side, like - 6mm. So even though all the individual lines are in tolerance, your delta between the A1 / B1 groups is quite large at 12 mm and would result in a slow trim? Thanks

you made up a good point there. en-c, 2 liners are one reason we made a webapp for everybody to check the trim of their gliders easy and fast online.
Thank you for sharing your knowledge and insight. Now I can check to see if lines need to be serviced.
Very good and comprehensive explanation, Tom 👏🏼👏🏼👏🏼
Really useful information, thanks Tom
Excelent video, Tom! Thanks!
Great info
Very informative. THANKS.
thanks for sharing!!! awesome info
Great stuff!

Good remark Patrick, that imbalance looks suspicious indeed, maybe one of the pros reading this can answer.
Such a great video. you have made it easy for us. how can I get my hands on the excel sheet ?

You might get one for your glider from the manufacturer website?
I couldn't get one ozone.

Any idea where I can find a line length chart for a Buzz 6?
