SYNTHETIC CONTROL LINES

Does anyone have an opinion on Sullivan synthetic contol lines? I am getting back into sport CL flying and finding a few new items that I am not familiar with.
Thanks,
Dave

They are terrible, don't waste any time trying them. You will be much better off with traditional stranded stainless lines.

AMEN. There are a lot of people with opinions on these and they are all about the same. They drag too much, they weigh too much. They are not legal in competition.

They are Great!! Absolutely perfect for staking off property lines and other landscaping uses.

Horrible for control line use though...

they are awful very heavy tons of drag and collect dirt

THANKS A LOT GUYS. I THINK I'VE GOT THE PICTURE.

They're great with CA for wrapping the ends of fiberglass and carbon pushrods to avoid splitting,but don't even try to fly with them.

THANKS RON!

Whenever this comes up, I like to tell this old story. When the kevlar lines first came out, I decided to try them on a fast combat plane. I used an old beater of a plane that went about 100 mph with the standard steel .018" lines.
With the kevlar lines, it went 90 mph, and I was looking at the prop nut the whole flight (the lines bowed so much the plane was pointed in at me!).
That was the end of that experiment.

But, But, But..... if you wrap your pushrods you are flying with them........ Sorry could not resist....
More seriously, I agree 100%......
Like many of us my first flights were with a McCoy (?) P40 on nylon lines... but after that, wire lines, MUCH safer.

Good for stooge release.

You got the point from the other posts about their intended use, but they are a good sorce of Kevlar thread for re-enforcement purposes. Look around at swap meets and such and pick them up cheap. Use the real for REAL flying lines
Good luck and have fun,

As an addendum to this.. yeah, the old Sullivan Kevlar lines might be junk, but there are potentially better non-conducting lines out there these days, in the form of Spectra-based fishing lines. From some of the experiments carried out so far, they work well on 1/2-A size models, but few have tried them with larger ones. The 100-150 lb Spectra kite lines would probably be overkill (and draggy). 50-60 lb. fishing line would be better, less diameter than steel lines of the same breaking strength (.018s).

Good for a stooge release. They last forever, and you don't have to be careful winding it up. Also easy to see on the ground.

In the same catagory as synthetic oil, they will half way do the job but you have to have the real thing (castor and stranded steel) to do the job right

I ordered a set of these when they first came out. One look at them and they went into my junk box where they have been ever since.
