Broadband over Power lines

Dan,

If you don't mind, could you post the area where you live?

I think you were joking, but it's not a good idea to fly near power lines at any time.

Mike

Not at all - I'm in Cincinnati...

Dan,

Interesting. Please keep the group informed on these happenings as they affect, or don't, R/C air.

My mention of not flying near power lines comes from numerous augers club members have had when flying near high voltage lines at our field.

An interesting side note is the power lines are a long way from the club's normal traffic pattern, and perhaps the incidents were caused more by visibility/orientation issues, than radio interference.

Of course in most R/C clubs, a crash is invariably caused by radio hits.

Thanks for the link. Mike

Well, power lines do sometimes emit RF noise, even without BPL. Once you can track it down, the electric company will usually act very quickly to fix it, but it's often not easy to track down. Your local hams may help if you're having problems with this (doesn't sound like you are.)

You've noticed that too, huh? :)

I once flew my sloper flying wing into a power line. It bounced off, recovered, no damage done, and I kept flying, being more careful not fly that far down anymore :)

On the other hand, this picture --

YEEEEEEOUCH! I always wondered why the warnings against flying near power lines; due to the potential for damage to the plane or wires, or the risk if interference. Now I guess I know!

I'mpressive - though the plane is clearly fried to a crisp, it must have been flown in to a decent landing, on fire, as the airframe is still in one piece!

ok why would the plane be fried or on fire ??

do birds fry or catch fire (under normal circumstances) when on the highwires ? I think not/// you must be grounded in order to complete a circuit to cause any combustion.

You've obviously never seen a raven try to do a hard turn between two lines and touch a wingtip to both. Poof!

Or seen birds landing (going poof) on the 500KV lines.

Line to line would actually be higher voltage than line to ground. He might have laid the wing across two wires, or made the gap close enough to jump the extra distance.

cant say as I have.......what a vision LOL !!

ROFLOL! Recognized the pictures as they hung on the LHS bulletin board for

It got hung up in the lines until all the monocote departed (rather abruptly!). That is how it got that way.

When you hit ONE line, the physical damage is limited to the structural hit from the wire. However when you CROSS TWO lines the results are spectacular. Turned the lights out in a subdivision.

BTW, it WAS a Telemaster. It was not my plane or my pictures, but I know who and where this happened.

Unless you bridge two separate lines.

Its very easy to get multipath reflections off lines, and totally null out the transmitter in certain spots.

Even a long wire fence is bad news.

Thats before any broadband gets on to them as well :-)

Interesting, I am surprised that made a difference. But obviously it did. Neat trick.

Depends on the set up of the power line. Or it may even be that the plane struck the line at the pylon and shorted out the insulator. Who knows...

Just curious, do you serve Red or White with Fried Telemaster?

They changed the wavelength of the fencing, thereby the intereference.

David

That one is easy. Crow! Club rules are to avoid the power lines. He broke them.

Almost all of those who have NOT hit the wires always claim they never get anywhere near them and surely do not go outside them. We only have two kinds of pilots, those that have and those that will.
