spectra lines
« on: April 24, 2018, 06:29:28 PM »

   I haven't had a chance to try these lines, but do have some questions, as they are not cable they shouldn't conduct static  electricity right? That should be a safety factor right there.
  Does anyone have some suggestions/experience with these lines in stunt use?
                   Thanks a lot... H^^

Strange, I thought all that had already been cussed and discussed for years and years. Would expect that a search would turn up plenty, tho you might need to use Google or DuckDuckGo (my new default search engine) to search at www.stunthanger.com. There should be some evidence easily found in the 1/2a forum. I hope this helps, but I'm pretty tuckered and not up to do the searching...plus dinner is about ready!

FWIW, I bought some to try for a .25 powered Tomahawk II. I think it's 40 lb test, and the color is Vermillion or Crimson...(red!). You can also get a nice blue, but either should show up better on grass than yellow or dark green. White is also available.   H^^ Steve

As stated a search should turn up several hours of reading. S?P

Dirty wet spectra conducts surprisingly well...

It doesn't matter what you use for lines if you like to fly near power lines or near thunderstorms.  The lines form a leader that lets the static charge jump to the plane.  After that the lines vaporize and you likely are dead.

Under clear skies with no storms around the electric field is around 100volts/meter.  60ft. lines can see around 500-600 volts between the plane and handle.  That results in the notorious static snap which was common with Easy Just handles.  The plastic handle provided insulation until your hand got close to the line adjustment tab.  That could give your hand a nasty static tickle.  Grounding the handle by wrapping some bare copper wire from around the handle to the lines lets the charge bleed off all the time with no  sparks.

I'm curious...not argumentative. Just how far from power lines do we need to be? I'm assuming we are talking high voltage, major transmission lines.
Or does this include the 110v lines from transformer to house/building?

I've stood about 150 feet from residential power lines and flown planes with .015 cables. Which may explain things.
I may be wrong but I doubt it.

A flyer in our area got KILLED flying CL too near to high voltage lines.

How high was the voltage?  I don't know and neither did he.

That's the essence of the question.  How do you know the voltage of the power line? 

If somebody actually made a table of voltages and distances the writer of the table would be held responsible when somebody got killed.

It's 1000 or 10,000 for each disc hanging at the pole. That's for the big stuff not local power lines.
