DSE 5 #1 August 26, 2007 Anyone got a Hawkeye with a cutaway on it? A guy at our DZ is not wanting to jump his Hawkeye without a cutaway, and I couldn't find anything for him. Suggestions? Quote Share this post Link to post Share on other sites
jee 0 #2 August 27, 2007 Check this out: http://www.aerostore.com/Shopping/ShowItem.asp?ItemID=A02475CT It should work on any helmet even with just a chin strap. I put one on a Nvertigo X with a chin cup. I tested it in the packing room and it seems to work pretty good. Quote Share this post Link to post Share on other sites

A jumper at my DZ custom made her own chincup cutaway system that has a 2-ring on it.~D Where troubles melt like lemon drops Away above the chimney tops That's where you'll find me.

everymansaved 0 #5 August 27, 2007 Yeah, I built a 2 ring cutaway for the chincup on my wife's FF2. It only took about 1hr of time and about $5-10 worth of parts. I can send you pictures/part list if you'd like.God made firefighters so paramedics would have heroes...and someone can put out the trailer fires.

champu 1 #6 August 28, 2007 I'm hesitant to put much faith in cotter pin style cutaway systems. Orientation of the forces associated with the entanglement, orientation of the handle relative the pin direction, and even minor oxidation of the components over time can result in a pretty useless setup when the shit actually hits the fan. I have a feeling there simply aren't enough helmet entanglement incidents for any kind of meaningful statistics to be gathered. A two-ring release system is simply better in just about every way.

The111 1 #7 August 28, 2007 I've always felt the same... although a cotter pin system is probably still better than nothing.www.WingsuitPhotos.com Quote Share this post Link to post Share on other sites
mrwrong 0 #8 August 28, 2007 Would TonFly cut system be an alternative? They have 2 different set up's. http://www.tonfly.com/Acc-ries_500973.html“The sum of intelligence on the planet is a constant; the population is growing.” - George Bernard Shaw He who dies with the most toys, wins..... dudeist skydiver # 19515 Buy quality and cry once!

champu 1 #9 August 30, 2007 Better... I can't tell from the photos on the site if I like it or not though... My concern with that setup is that you have a Lolon coated cable passing through a hole in a metal pin. When a sheer force is applied to the head of the pin as you tighten the helmet, the pin will tilt and the edge of the hole the cable passes through will want to bite into the Lolon coating, locking the whole thing up. You can design the components so that this won't be an issue, but as I said I can't tell from the photos on the site if the manufacturers did so or not.

mrwrong 0 #10 August 30, 2007 Well you se, that is the beauty with Tonfly's cut system. The metal pin that the (the new cut system has a cutwire)* cutwire goes through is 360 degrees rotating so it doesn't matter what way you are pulling the handle Take a closer look at there web site, you'll be able to find both a video and a tech doc in PDF format where everything is explained. *the old cut system has a metal pin instead of a wire. “The sum of intelligence on the planet is a constant; the population is growing.” - George Bernard Shaw He who dies with the most toys, wins..... dudeist skydiver # 19515 Buy quality and cry once!

champu 1 #11 August 31, 2007 The pull test results were good news, but the pull direction wasn't what I was referring to. Since a picture is worth a 1000 words, see attachment for what I'm talking about. Note particularly: intended pin axis, force, displaced pin axis due to force, and pinch point I'm concerned about the lolon coating riding up the edge of the hole through which it passes on the back side of the pin and binding there. /edited to add: can you tell I'm a real blast to have around at parties? hahaha Quote Share this post Link to post Share on other sites
mrwrong 0 #12 August 31, 2007 Yep. I se what you mean. And it's the newer Tonfly system that has this lolon coated wire. It's called something like TF Plus. The slightly older cut system doesn't have any coated wire at all, just a metal pin joint with a coated wire that's the actual cut handle. So NO chance h**l for the scenario you are describing with the older Tonfly system “The sum of intelligence on the planet is a constant; the population is growing.” - George Bernard Shaw He who dies with the most toys, wins..... dudeist skydiver # 19515 Buy quality and cry once!
