I posted the picture of the helicopter and the tree triming saw.
My question is what did I do incorrectly to have it appear differantly than other pictures? No credit, and the photo tags showing.

Unless you changed it?, I see photo credit, description, and airport - only registration number is blank.

The only thing different I see, is 23 people, including myself, voted for your picture, and the Staff at FlightAware have posted it - 'Staff Picks This Weeks'.

As long as your logged onto FlightAware, you can click on your own photo, and change the information below the photo any time you want.

wingnut -- the page looks a bit different if you're the uploader. It shows proper credit and info to others.

Log out and look at the photo and you will see all the information you are looking for.

Crazy wingnut - I actually saw that pic you posted last week and had never heard of such, did some research and found a couple of vids on youtube of their work. What a wild piece of equip!

Great picture though.

One of the lead companies in this field is out of Gettysburg, PA.

Yeah J - we had another discussion about Haverfield's powerline inspections in here a while back:

What a wild company!

How do they keep the saw lined up with the work? I'd think it would be spinning wildly.

I've wondered that too - it must be weighted pretty heavily. And what happens when that chain/cable carrying those saws gets tangled up in a power line?

I'm guessing the blades are counter rotating to minimize kickback.

Their most senior pilot is 22. :P Actually, it appears the chain/cable is insulated.

my idea of flying is of fun, not doing the friggin yard work jeez. This makes it a chore!


Looks like the pilot has to keep that thing pretty accurate, he's awefully close to those power lines, and good gust of wind or something might get ugly!

22 yrs old?? I'm sure that's a dangerous biz, but didn't realize it was that dangerous! And as far as the insulation, I wasn't really talking about an electrical current so much as it getting wrapped around something and pulling that helicopter down. I wonder if it has some kind of disconnect in the event it gets hung up?

I don't think so. Look at the way the teeth on all the blades are pointing...

Good observation young Will. In this case counter rotation would be counter productive.

Gyroscopic effect of the spinning blades makes it stable as to orientation when in operation. Multi-point suspension system makes it stable in flight.

Same quick disconnect as any other sling-load AFAIR.

No insulation, unnecessary as the aircraft isn't grounded and if they hit a cable electrocution is the least of their worries.

Doesn't anyone remember James Bond's BMW being cut in half by one of these?

Gyroscopic effect might not be an issue if the blades aren't spinning very fast.

In this instance Jason, gyroscopic effects would be a good thing, like a spinning bicycle wheel, so faster is better.

I remember seeing this rig many years ago at KRSN. We were bumming at the airport when we see this vertical line moving through the sky. After checking to make sure it was just Coke we were drinking, we realized it was attached to a helicopter. We talked with the crew after they landed. The pilot told us how dangerous the mission is, and how many accidents have been had. He said he keeps his finger over the jettison switch at all times in case it snags. He said the only chance to survive is to jettison immediately, before the helicopter gets pulled down. They strip the interior to nothing but the pilot seat to lose weight. He said they many are used for rough and wet areas, places ground equipment simply can't get to.
