I get my wing line and the line for the club at Memphis net and Twine
https://www.memphisnet.net/category/...tebraidedseine


For personal or club use I would recommend #21 if you are mostly 2M or woodies. If you are flying mostly composite ships then #24. I have #24 on my winch.

For active contest use I would use #24 or #30.

I think the Eastern Soaring League has used #30

I have #9 on my retriever.

I have more than a few rolls of this that I can sell.
It is from Samson Rope Co.
It's a continuous 2lbs worth of 300lb line.
$22 each plus shipping. I've tried and tested many types of line, these are the most consistent and one of if not the best in my opinion.

$19 for 100 feet X 12 for 1200 feet of line (600 out and 600 back)

That would be $228, assuming you only use 1200 feet. FWIW, LSF limt is over 900 feet for LSF tasks. that would take 1800 feet of line or $342.

Or you can buy regular winch line for about $15 or $20 for 1200 feet or $30 to $40 for 1800 feet. Rough round numbers.

Your call.

Not to mention, 750# Kevlar will have zero stretch. I'd also worry about it's ability to quickly sever anything that gets caught on the line.

What Wazmo said...!!! I used 225# dacron... once. If you use line with no stretch, you had better be ready to throw the glider the instant you touch the pedal. If not it will be ripped from your hand... See above and you'll know how I know...

Very good point about the stretch Nylon has some stretch which allows you to tension the line before release. For light models you only tension a little. For high end composite models you tension a lot.

For F3J they don't use braided nylon they use monofilament which REALLY stretches and that stretch is part of the launch power.

So, the advantages of nylon for cost and for character are well established.


BTW, no matter what you use you really need to throw the glider. That was always drummed into me as I was learning. This weekend it paid off. I was launching my Supra. Tensioned up the line and threw. A second later the line broke. No idea why but the glider was already turning nose up when it happened.

Fortunately I had thrown it enough that it had sufficient forward air speed for me to control it and land it safely. If I had just let the line take it out of my hand it would have likely crashed.

I wouldn't use a line that was completely Kevlar. I was thinking 50 past the turnaround and I would add Nylon line for the stretch 50 feet from the parachute on out. The Kevlar would be mainly in the high stress area of the line.

This past weekend, I had the line break on my launch, about 10' out. Since I just started TD and I am new to a winch, throwing is something I need to work on. Anyhow, I came down on the left wing tip, followed by the nose and then the left wing tip.

I got lucky, ... no damage, however, ... I did learn a valuable lesson!

THROW IT!

Bill

Leave the Kevlar off completely! No stretch at all, the fifty feet of nylon won't have enough stretch to notice.

It is often the knots used that cause line breaks. Look up Knot Wars online and select knots that have the highest percentage of line strength...

Bimini Twist Knot, ... the main knot used in catching monster Marlin and Tuna, ... 2 things that can easily out-pull any winch launching an RC sailplane.
